For instance, the [`speaker`] peripheral allows a\ncomputer to play music and the [`monitor`] peripheral allows you to display text\nin the world.\n\n## Referencing peripherals\n\nComputers can interact with adjacent peripherals. Each peripheral is given a\nname based on which direction it is in. For instance, a disk drive below your\ncomputer will be called `"bottom"` in your Lua code, one to the left called\n`"left"` , and so on for all 6 directions (`"bottom"`, `"top"`, `"left"`,\n`"right"`, `"front"`, `"back"`).\n\nYou can list the names of all peripherals with the `peripherals` program, or the\n[`peripheral.getNames`] function.\n\nIt\'s also possible to use peripherals which are further away from your computer\nthrough the use of [Wired Modems][`modem`]. Place one modem against your computer\n(you may need to sneak and right click), run Networking Cable to your\nperipheral, and then place another modem against that block. You can then right\nclick the modem to use (or *attach*) the peripheral. This will print a\nperipheral name to chat, which can then be used just like a direction name to\naccess the peripheral. You can click on the message to copy the name to your\nclipboard.\n\n## Using peripherals\n\nOnce you have the name of a peripheral, you can call functions on it using the\n[`peripheral.call`] function. This takes the name of our peripheral, the name of\nthe function we want to call, and then its arguments.\n\n> [!INFO]\n> Some bits of the peripheral API call peripheral functions *methods* instead\n> (for example, the [`peripheral.getMethods`] function). Don\'t worry, they\'re the\n> same thing!\n\nLet\'s say we have a monitor above our computer (and so "top") and want to\n[write some text to it][`monitor.write`]. We\'d write the following:\n\n```lua\nperipheral.call("top", "write", "This is displayed on a monitor!")\n```\n\nOnce you start calling making a couple of peripheral calls this can get very\nrepetitive, and so we can [wrap][`peripheral.wrap`] a peripheral. This builds a\ntable of all the peripheral\'s functions so you can use it like an API or module.\n\nFor instance, we could have written the above example as follows:\n\n```lua\nlocal my_monitor = peripheral.wrap("top")\nmy_monitor.write("This is displayed on a monitor!")\n```\n\n## Finding peripherals\n\nSometimes when you\'re writing a program you don\'t care what a peripheral is\ncalled, you just need to know it\'s there. For instance, if you\'re writing a\nmusic player, you just need a speaker - it doesn\'t matter if it\'s above or below\nthe computer.\n\nThankfully there\'s a quick way to do this: [`peripheral.find`]. This takes a\n*peripheral type* and returns all the attached peripherals which are of this\ntype.\n\nWhat is a peripheral type though? This is a string which describes what a\nperipheral is, and so what functions are available on it. For instance, speakers\nare just called `"speaker"`, and monitors `"monitor"`. Some peripherals might\nhave more than one type - a Minecraft chest is both a `"minecraft:chest"` and\n`"inventory"`.\n\nYou can get all the types a peripheral has with [`peripheral.getType`], and check\na peripheral is a specific type with [`peripheral.hasType`].\n\nTo return to our original example, let\'s use [`peripheral.find`] to find an\nattached speaker:\n\n```lua\nlocal speaker = peripheral.find("speaker")\nspeaker.playNote("harp")\n```\n\n@module peripheral\n@see event!peripheral This event is fired whenever a new peripheral is attached.\n@see event!peripheral_detach This event is fired whenever a peripheral is detached.\n@since 1.3\n@changed 1.51 Add support for wired modems.\n@changed 1.99 Peripherals can have multiple types.\n]]\n\nlocal expect = dofile("rom/modules/main/cc/expect.lua").expect\n\nlocal native = peripheral\nlocal sides = rs.getSides()\n\n--- Provides a list of all peripherals available.\n--\n-- If a device is located directly next to the system, then its name will be\n-- listed as the side it is attached to.

For example, the Multishell system functions by assigning each tab\na window covering the screen, each using the starting terminal display as its\nparent, and only one of which is visible at a time.\n\n@module window\n@since 1.6\n]]\n\nlocal expect = dofile("rom/modules/main/cc/expect.lua").expect\n\nlocal tHex = {\n [colors.white] = "0",\n [colors.orange] = "1",\n [colors.magenta] = "2",\n [colors.lightBlue] = "3",\n [colors.yellow] = "4",\n [colors.lime] = "5",\n [colors.pink] = "6",\n [colors.gray] = "7",\n [colors.lightGray] = "8",\n [colors.cyan] = "9",\n [colors.purple] = "a",\n [colors.blue] = "b",\n [colors.brown] = "c",\n [colors.green] = "d",\n [colors.red] = "e",\n [colors.black] = "f",\n}\n\nlocal type = type\nlocal string_rep = string.rep\nlocal string_sub = string.sub\n\n--[[- Returns a terminal object that is a space within the specified parent\nterminal object.

Additional Definitions.\n\nAs used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License.\n\n"The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below.\n\nAn "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library.\n\nA "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version".\n\nThe "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version.\n\nThe "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work.\n\n1. Exception to Section 3 of the GNU GPL.\nYou may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL.\n\n2. Conveying Modified Versions.\nIf you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version:\n\n a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or\n\n b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy.\n\n3. Object Code Incorporating Material from Library Header Files.\nThe object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following:\n\n a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License.\n\n b) Accompany the object code with a copy of the GNU GPL and this license document.\n\n4. Combined Works.\nYou may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following:\n\n a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License.\n\n b) Accompany the Combined Work with a copy of the GNU GPL and this license document.\n\n c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document.\n\n d) Do one of the following:\n\n 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.\n\n 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user\'s computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version.\n\n e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.)\n\n5. Combined Libraries.\nYou may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following:\n\n a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License.\n\n b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.\n\n6. Revised Versions of the GNU Lesser General Public License.\nThe Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.\n\nEach version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation.\n\nIf the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall\napply, that proxy\'s public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.\n\nGNU GENERAL PUBLIC LICENSE\nVersion 3, 29 June 2007\n\nCopyright \xa9 2007 Free Software Foundation, Inc. <http://fsf.org/>\n\nEveryone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.\n\nPreamble\n\nThe GNU General Public License is a free, copyleft license for software and other kinds of works.\n\nThe licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.\n\nWhen we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.\n\nTo protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.\n\nFor example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.\n\nDevelopers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.\n\nFor the developers\' and authors\' protection, the GPL clearly explains that there is no warranty for this free software. For both users\' and authors\' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.\n\nSome devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users\' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.\n\nFinally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.\n\nThe precise terms and conditions for copying, distribution and modification follow.\n\nTERMS AND CONDITIONS\n\n0. Definitions.\n\n"This License" refers to version 3 of the GNU General Public License.\n\n"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.\n\n"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.\n\nTo "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.\n\nA "covered work" means either the unmodified Program or a work based on the Program.\n\nTo "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.\n\nTo "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.\n\nAn interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.\n\n1. Source Code.\nThe "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.\n\nA "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.\n\nThe "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.\n\nThe "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work\'s System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.\n\nThe Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.\n\nThe Corresponding Source for a work in source code form is that same work.\n\n2. Basic Permissions.\nAll rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.\n\nYou may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.\n\nConveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.\n\n3. Protecting Users\' Legal Rights From Anti-Circumvention Law.\nNo covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.\n\nWhen you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work\'s users, your or third parties\' legal rights to forbid circumvention of technological measures.\n\n4. Conveying Verbatim Copies.\nYou may convey verbatim copies of the Program\'s source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.\n\nYou may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.\n\n5. Conveying Modified Source Versions.\nYou may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:\n\n a) The work must carry prominent notices stating that you modified it, and giving a relevant date.\n\n b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".\n\n c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.\n\n d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.\n\nA compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation\'s users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.\n\n6. Conveying Non-Source Forms.\nYou may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:\n\n a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.\n\n b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.\n\n c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.\n\n d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.\n\n e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.\n\nA separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.\n\nA "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.\n\n"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.\n\nIf you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).\n\nThe requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.\n\nCorresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.\n\n7. Additional Terms.\n"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.\n\nWhen you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.\n\nNotwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:\n\n a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or\n\n b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or\n\n c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or\n\n d) Limiting the use for publicity purposes of names of licensors or authors of the material; or\n\n e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or\n\n f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.\n\nAll other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.\n\nIf you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.\n\nAdditional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.\n\n8. Termination.\nYou may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).\n\nHowever, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.\n\nMoreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.\n\nTermination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.\n\n9. Acceptance Not Required for Having Copies.\nYou are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.\n\n10. Automatic Licensing of Downstream Recipients.\nEach time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.\n\nAn "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party\'s predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.\n\nYou may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.\n\n11. Patents.\nA "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor\'s "contributor version".\n\nA contributor\'s "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.\n\nEach contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor\'s essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.\n\nIn the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.\n\nIf you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient\'s use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.\n\nIf, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.\n\nA patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.\n\nNothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.\n\n12. No Surrender of Others\' Freedom.\nIf conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.\n\n13. Use with the GNU Affero General Public License.\nNotwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.\n\n14. Revised Versions of this License.\nThe Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.\n\nEach version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.\n\nIf the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy\'s public statement of acceptance of a version permanently authorizes you to choose that version for the Program.\n\nLater license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.\n\n15. Disclaimer of Warranty.\nTHERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n\n16. Limitation of Liability.\nIN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.\n\n17. Interpretation of Sections 15 and 16.\nIf the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.\n\nEND OF TERMS AND CONDITIONS\n\n## Cobalt (https://github.com/SquidDev/Cobalt)\nThe MIT License (MIT)\n\nOriginal Source: Copyright (c) 2009-2011 Luaj.org.

Instead, it is a standard program, which injects\nits API into the programs that it launches. This allows for multiple shells to\nrun at the same time, but means that the API is not available in the global\nenvironment, and so is unavailable to other [APIs][`os.loadAPI`].\n\n## Programs and the program path\nWhen you run a command with the shell, either from the prompt or\n[from Lua code][`shell.run`], the shell API performs several steps to work out\nwhich program to run:\n\n 1. Firstly, the shell attempts to resolve [aliases][`shell.aliases`]. This allows\n us to use multiple names for a single command. For example, the `list`\n program has two aliases: `ls` and `dir`. When you write `ls /rom`, that\'s\n expanded to `list /rom`.\n\n 2. Next, the shell attempts to find where the program actually is. For this, it\n uses the [program path][`shell.path`]. This is a colon separated list of\n directories, each of which is checked to see if it contains the program.\n\n `list` or `list.lua` doesn\'t exist in `.` (the current directory), so the\n shell now looks in `/rom/programs`, where `list.lua` can be found!\n\n 3. Finally, the shell reads the file and checks if the file starts with a\n `#!`. This is a [hashbang][], which says that this file shouldn\'t be treated\n as Lua, but instead passed to _another_ program, the name of which should\n follow the `#!`.\n\n[hashbang]: https://en.wikipedia.org/wiki/Shebang_(Unix)\n\n@module[module] shell\n@changed 1.103.0 Added support for hashbangs.\n]]\n\nlocal make_package = dofile("rom/modules/main/cc/require.lua").make\n\nlocal multishell = multishell\nlocal parentShell = shell\nlocal parentTerm = term.current()\n\nif multishell then\n multishell.setTitle(multishell.getCurrent(), "shell")\nend\n\nlocal bExit = false\nlocal sDir = parentShell and parentShell.dir() or ""\nlocal sPath = parentShell and parentShell.path() or ".:/rom/programs"\nlocal tAliases = parentShell and parentShell.aliases() or {}\nlocal tCompletionInfo = parentShell and parentShell.getCompletionInfo() or {}\nlocal tProgramStack = {}\n\nlocal shell = {} --- @export\nlocal function createShellEnv(dir)\n local env = { shell = shell, multishell = multishell }\n env.require, env.package = make_package(env, dir)\n return env\nend\n\n-- Set up a dummy require based on the current shell, for loading some of our internal dependencies.\nlocal require\ndo\n local env = setmetatable(createShellEnv("/rom/programs"), { __index = _ENV })\n require = env.require\nend\nlocal expect = require("cc.expect").expect\nlocal exception = require "cc.internal.exception"\n\n-- Colours\nlocal promptColour, textColour, bgColour\nif term.isColour() then\n promptColour = colours.yellow\n textColour = colours.white\n bgColour = colours.black\nelse\n promptColour = colours.white\n textColour = colours.white\n bgColour = colours.black\nend\n\nlocal function tokenise(...)\n local sLine = table.concat({ ... }, " ")\n local tWords = {}\n local bQuoted = false\n for match in string.gmatch(sLine ..
