Calvin Rose 55cf9f5e1c Don't break reverse backwards compat. 
Breaking backwards compatibiliy here is not worth it.
Also update changelog.
 2020-07-03 10:17:50 -05:00
Calvin Rose 97c64f27ff Remove duplicate code in loop macro. 
Also evaluate for loop and range step exactly once.
Multiple evaluations can be inefficent and make infinite loop
detection impossible.

Calvin Rose 7fb8c4a68d Merge branch 'master' of github.com:janet-lang/janet 2020-06-29 22:57:46 -05:00
Calvin Rose 647fc56d47 Replace for with forv in most places in boot.janet 
Generates slightly better bytecode with current compiler
(gets rid of a single extra move instruction per loop iteration).

Calvin Rose 977b0c3c0c
Merge pull request #429 from pepe/fix-reverse-doc 
Tune reverse[d] docstrings
 2020-06-29 20:55:04 -05:00
Calvin Rose 17a131ac21 Add peg/find and peg/find-all. 
These peg functions should make pegs a bit easier to use
and more efficient in some common cases.
 2020-06-29 19:13:06 -05:00
Josef Pospíšil 289de840fd Specify input types actions 2020-06-28 20:49:44 +02:00
Calvin Rose 95c633914f Add auto-resizing of gc interval. 
This should prevent over use of GC and O(n^2)
behavior.
 2020-06-27 16:51:20 -05:00
Josef Pospíšil 7b033a48a3 Wrap both reverse and reversed docstring to 80 chr 2020-06-25 09:43:10 +02:00

Calvin Rose 6c917f686a Add :h default peg class, as well as ad \v to whitespace. 2020-06-24 08:40:23 -05:00
Calvin Rose 328ee94412 Merge branch 'master' into ev 2020-06-22 22:25:44 -05:00
Calvin Rose 803f17aa90 Add eachy and repeat to make looping easier. 
Like eachk and eachp, use eachy and repeat to bring loop
verbs outside of the loop macro. These new macros are very simple
and easy to understand, in contrast to the loop macro which is of
medium complexity.
 2020-06-21 18:48:06 -05:00
Calvin Rose 08a3687eb5 Fix #428 
Add binding check for generate verb in loops. The check is present
in other loop verbs.

 2020-05-23 11:33:19 -04:00
Calvin Rose 41f8be2c53 Fix flycheck when using the `use` macro. 
Flycheck originally expected `use` to have
the same arguments as `import`, but this is not the case.

Get expected behaviour; cleanup after confirming behaviour is desired 2020-05-20 22:40:05 +01:00
Calvin Rose e623690295 Use keywords in the assembly interface. 
This is simply more idiomatic, removes some unused and undocumented
features of the assembly interface, and simplifies it somewhat.
 2020-05-19 13:51:39 -05:00
Calvin Rose b7cfc08fc5 Improve line and col tracking in parser. 
Unconditionally add line and column information if
a parsed value is a tuple - before, some parsed tuples
had line and col information omitted.
 2020-05-18 19:05:27 -05:00
Calvin Rose 92f0e1719b Be less eager to set macro-form in macex1. 2020-05-18 18:37:41 -05:00
Calvin Rose 9e5f203302 Expose line, col in macros via (dyn :macro-form) 
This exposes line and column indirectly via
tuple/sourcemap and allows interesting debug macros.
 2020-05-18 18:27:35 -05:00
Calvin Rose df32cd0aca Update tracev macro to be simpler and single arity. 
Reference #401

Incorporate suggestions from PR 2020-05-16 20:18:00 +01:00
Calvin Rose 1bb9a9368b Make sure winsock2.h is included before windows.h 
This should be true in the normal build, and especially in the
amalgamated build.
 2020-05-16 12:41:26 -05:00

Calvin Rose 5d1fd390a6 Fix debugger regression. 2020-05-02 23:40:00 -05:00
Calvin Rose 1dc32d5e3d Revert inclusion of dedent. 
Dedent has been moved to spork as misc function.
There are two many different, incompatible ways to 'dedent'
as string, and it seems rather specific to add to the core like it is.
 2020-04-30 21:35:22 -05:00
Calvin Rose bee415217d Fix extra bindings. 2020-04-29 21:57:19 -05:00

Calvin Rose 84974d6c56 Make repl printing work from current environment. 
Although this "unprotects" output in the repl, people
in a repl usually want control, not protection.

Also re-add circular dependency detection.
 2020-04-19 09:38:18 -05:00
Calvin Rose 3e60e82529 Add circular dependency detection. 
This detection will not stop compilation, as errors
in general do not stop compilation unless exit on error
is passed inside an import, but should notify the user something
is going on.
 2020-04-19 09:35:14 -05:00
Calvin Rose 60f8dd0bfc Renable :source argument to dofile. 
Allows for some more interesting usage of
loaders.

Same for accumulate 2.
 2020-03-27 12:45:40 -05:00
Calvin Rose 3eb0927a2b Add accumulate(2) and reduce2

Calvin Rose d3b9b8d452 For #293, correct wildcards in dictinoaries. 2020-03-07 10:13:10 -06:00
Calvin Rose c864828735 Address #293 - wildcard to match macro. 
The _ symbol will match any value without creating a binding.
 2020-03-07 09:40:02 -06:00
Calvin Rose e0c9910d85 Add :range-to and :down-to to loop. 
Fully inclusive ranges are generally useful and
do not complicate implementation much.
 2020-03-07 09:34:11 -06:00
Calvin Rose e351dde651 Update CHANGELOG.md and docs for loop and pp. 2020-03-06 17:12:06 -06:00

Calvin Rose 734c85d7ef Properly handle recursion with labels. 
Use an empty buffer, which has pointer equality semantics, for
tag from a label.
 2020-02-23 17:35:01 -06:00
Calvin Rose 05bd5767de Add label macro. 
A lexically scoped version of prompt is often useful.
 2020-02-23 17:15:04 -06:00
Calvin Rose 59d288c429 Add `prompt` and `return`. 
User friendly delimited continuations. While this was doable with
signals before, this does not require C and will play nicely with
existing error handling, defers, and with statements.
 2020-02-23 16:46:54 -06:00
Calvin Rose 6a13703e32 Add `signal` and `fiber/can-resume?`. 
These additions, along with the change that user signals 0-4 cannot
be resumed, allow delimited continuation semantics, while repsecting
existing forms like `defer`, `with`, `with-vars`, etc.
 2020-02-23 13:31:27 -06:00
Calvin Rose aaabca6fc7 Make flychecker handle more kinds of defs. 
This should help when redefining certain forms. Will also
not do functional arity checking against nil forms, as that
is the default value when a def doesn't evaluate.
 2020-02-21 21:20:40 -06:00
Calvin Rose b9a2bb8104 Fix documentation for defer. 2020-02-12 09:34:23 -06:00
Calvin Rose 8ae6ae65a1 Merge branch 'master' into net 2020-02-09 20:00:58 -06:00
Calvin Rose f4d7fd97f6 Working TCP echo server and client. 
Required a few changes to APIs, namely janet_root_fiber()
to get topmost fiber that is active in the current scheduler.
This is distinct from janet_current_fiber(), which gets the bottom
most fiber in the fiber stack - it might have a parent, and so cannot
be reliably resumed.
This is the kind of situation that makes symmetric coroutines more
attractive.
 2020-02-09 20:00:50 -06:00
Calvin Rose fcc09d7ea9 Clarify docs for `some` and `all`. 2020-02-05 21:06:39 -06:00
Calvin Rose 7f1f684b21 Merge branch 'master' into net 2020-02-03 20:46:32 -06:00
Calvin Rose 3fdc053d6c Add flush and eflush (#278) 
These functions interact with Janet's dynamically scoped
IO functions in a manner that is more useful the file/flush.
We can still redirect to a buffer without changing our code.

Humble beginnings.
 2020-02-01 20:39:54 -06:00
Calvin Rose 333ae7c4f8 Make amalgamtion the default when building. 
This way we can support fewer build configurations. Also, remove
all undefined behavior due to use of memcpy with NULL pointers. GCC
was exploiting this to remove NULL checks in some builds.
 2020-01-28 23:38:52 -06:00
Calvin Rose f7b7c83264 Address #276 2020-01-25 12:08:43 -06:00

Calvin Rose 689f2dcbb4 Change default import prefix.

debug/stacktrace was being called incorrectly.
 2020-01-20 16:05:08 -06:00
Calvin Rose f4ad627b54 Fix regression in while loops inside each macros. 
There was a specialization for `(while (not= nil _) ...)` that
was incorrect when the while loop regresses to a thunk.
 2020-01-19 16:25:10 -06:00
Calvin Rose da70807292 Make autocompletion more zsh like 
Also add a few ctrl sequences from readline, and
ignore unknown ctrl sequences.

Address #264

Adds Ctrl-n, Ctrl-p, and Ctrl-w
Ignores unknown ctrl sequences
No alt-* sequences yet.
 2020-01-19 10:38:35 -06:00
Calvin Rose 064475cb8d Add eachk and eachp. 
These should make iterating over datastructures easier
without needing the loop macro.
 2020-01-18 18:46:49 -06:00
Calvin Rose 51678c1aba Extend power of the each form 
This changes the implementation of the `next` function which
is now used to implement each. This let's us iterate over
more types, not just tables and structs.
 2020-01-18 17:55:07 -06:00

It was the same as when-with.
 2020-01-16 18:12:05 -06:00
Calvin Rose 174ff87946 Change printing of abstracts with tostring in pp 
This change makes pretty printing not hide "abstractness".
 2020-01-16 18:10:17 -06:00

This is useful for reading from files.

Calvin Rose f709d7eb40 Add `module/add-paths` 
This should make it much easier to make custom DSLs work
well with the import system. No need to mess about with import paths,
 things will just work.
 2020-01-12 20:59:45 -06:00
Calvin Rose a68ee7aac6 Update Copyright 2020. 2020-01-12 10:50:37 -06:00
Calvin Rose 099a957e6c Update macex1 to properly handle break 
Things mostly worked fine, but technically
break should be handled as a special form not a function call.
 2019-12-29 16:44:53 -05:00
Calvin Rose 5142722da3 Remove aliases for deprectaed functions. 2019-12-28 17:51:05 -05:00
Calvin Rose 022be217a2 Remove ==, not==, and order[<,<=,>,>=]. 
This unifies equality and comparison checking. Before, we had
separate functions and vm opcodes for comparing general values vs.
for comparing numbers, where the numberic functions were polymorphic and
had special cases for handling NaNs. By unfiying them, abstract types
can now better integrate with other number types and behave as keys.

For now, the old functions are aliased but will eventually be removed.
 2019-12-28 16:04:15 -05:00
Calvin Rose f1afc5b0b4 Address #214 
This adds several common patterns, which are defined in
boot.janet. This essentially gives more primitive patterns
to work with out of the box.

Fix build when JANET_REDUCED_OS is defined.
 2019-12-14 20:39:14 -06:00
Calvin Rose 5b9eda5e87 Add root-env 
This makes images smaller without needing to make sure
that no references to the root environment occur in the final
image.
 2019-12-12 17:25:04 -06:00
Calvin Rose 36b2f27873 Merge branch 'master' into threads-3 2019-12-12 17:07:03 -06:00
Calvin Rose 1a6eb52f11 Add protect macro. 
A more functional version of try catch.

 2019-12-06 19:54:11 -06:00
Calvin Rose 4de6c2ad61 Address #211 
Scripts run from the command line will automatically

Calvin Rose dbcceefc20 Fix bad merge. 2019-12-04 22:41:30 -06:00
Calvin Rose 1a4035b02c Merge branch 'master' into threads-3 2019-12-04 22:39:30 -06:00
Calvin Rose 49954c7a30 Remove top-level unquote for comptime macro 
True top level unquote currently requires basically double compilation
as it currently stands. Also, implementing such double compilation
looses all source mapping information. This is a compromise
implementation that makes it clear that this works differently than
a true top-level unquote.
 2019-12-04 19:53:13 -06:00
Calvin Rose 2487162ccf Add top level unquote and macro envs. 
This improves macros that eval their arguments and
makes them easier to write.
 2019-12-04 18:39:13 -06:00
Calvin Rose f39cf702db Address #212 - don't include janet args in script args. 2019-12-04 08:30:36 -06:00

Calvin Rose 3a14aad615 Address issue #205. 2019-12-02 18:34:08 -06:00
Calvin Rose 70c8b6838d Use make-image-dict and load-image-dict in thread/new 
Rather than messing with janet_core_dictionary, we
instead cache the core enevironment, and pull out the
needed tables from there. This is more flexible, more correct, and
also exposes janet_resolve_core, which can be easily used from the C
API.
 2019-12-02 04:15:22 -06:00
Calvin Rose 212479188a Have separate encode and decode dicts for threads 
This is more correct and mirrors the way marshal -> unmarshal works.
 2019-12-01 21:53:39 -06:00
Calvin Rose 6a763aac95 Work on threads. 
Add send and receive.
 2019-12-01 20:28:12 -06:00
Calvin Rose 5cd6580c2d Merge branch 'threads-3' of github.com:janet-lang/janet into threads-3 2019-12-01 20:25:57 -06:00
Andrew Chambers ded08b6e1e Add truthy? to core. 2019-12-01 14:34:41 +13:00
Calvin Rose bca0392738 First work on threading. 
Posix only, needs to be disabled on windows. Also
the Makefile needs to be configurable, and meson.build
needs to take pthreads into account.
 2019-11-26 23:13:53 -06:00
Calvin Rose 7df0ec6aed Fix up debug/step and janet_step. 
Also allow debugging on all signals, including errors.
This is gated behind (setdyn :debug true) in the repl.
 2019-11-25 20:00:13 -06:00
Calvin Rose d37c43716a Lots of work on improving debugging. 
doc macro can take no arguments and print out
all bindings. Fix an issues with the vm skipping
over a breakpoint in some situations.

Add examples/debugger.janet for proof of concept
debugger.
 2019-11-24 17:45:53 -06:00
Calvin Rose 5171dfd2a8 Fix docstring. 2019-11-16 20:43:21 -06:00
Calvin Rose bcd2089f71 Version 1.5.1 2019-11-16 17:17:13 -06:00
Calvin Rose 7553b277db Fix return value of update. 2019-11-16 15:50:21 -06:00
Calvin Rose aee1687215 Add RNG functionality to the math/ module. 
The new RNG wraps up state for random number generation, so
one can have many rngs and even marshal and unmarshal them.
Adds math/rng, math/rng-uniform, and math/rng-int.

Also introduce `in` and change semantics for
indexing out of range. This commit enforces stricter
invariants on keys when indexing via a function call
on the data structure, or the new `in` function.

The `get` function is now more lax about keys, and will
not throw an error when a bad key is used for a data structure, instead
returning the default value.
 2019-11-08 17:40:04 -06:00
Calvin Rose cf2d3861d6 Make slice a c function. 
This will allow future integration into the compiler
for more general destructuring.
 2019-11-05 09:29:32 -06:00
Calvin Rose 6ceaf9d28d Add with-vars 
This helps for temporarily setting vars in a safe
manner that is guaranteed not to leave vars in a bad state
(assuming that a fiber does not emit debug or use signal and
 is never resumed).
 2019-10-31 21:58:43 -05:00
Calvin Rose 2541806dc1 Fix suite7 failing when run with no docstrings. 2019-10-29 18:28:41 -05:00
Calvin Rose 0d16b9e1a1 Move init.janet into cli-main in boot.janet 
This makes it easier to get the CLI functionality when
embedding Janet, although the main reason is the init script
is now pre-compiled to bytecode when generating the boot image.
 2019-10-29 18:16:32 -05:00
Calvin Rose 45c2819068 Improve flychecking. 
Flychecking will now work correctly with arity checking, and
will better handle imports. Well structured modules should interact
cleanly with the flychecker in a mostly safe manner, but maliciously
crafted modules can execute arbitrary code. As such, the flychecker is
not a good way to validate completely untrusted modules.

We also extend run-context with an :evaluator option to replace
:compile-only. This is more flexible and allows users to create their
own flychecker like functionality.
 2019-10-27 16:15:41 -05:00
Calvin Rose 8dd8af742a Add eprintf and make printf a C function. 
This allows some more optimizations when printing to
buffers or when output is disabled. It also makes printf
more consistent with print and prin (Same with eprintf).
 2019-10-19 10:30:29 -05:00
Calvin Rose d47804d222 Add prin, eprint, and eprin functions. 
The print family of functions now writes output
to an optional buffer instead of a file bound to :out.
This means output can be more easily captured an redirected.
 2019-10-19 09:44:27 -05:00
Calvin Rose a18a251d16 Address some issues found in lgtm 
Caught a few potentially issues with overflows, as well as use of
unsafe function localtime.
 2019-10-10 22:59:43 -05:00
Calvin Rose f780df0aa6 Fix single threaded build option with meson. 
By default, was building with the opposite of what was provided.
 2019-10-05 20:35:11 -05:00
Calvin Rose e9f3dc7d5c Add varfn. 2019-10-03 20:20:42 -05:00
Calvin Rose 70ffe3b6bd Add slice function to core. 
Returns immutable slices.
 2019-09-24 19:44:36 -05:00
Calvin Rose a8afc5b81f Sourcemapping uses line, column instead of offsets. 
This should be friendlier to most users. It does, however, mean
we lose range information. However, range information could be
recovered by re-parsing, as janet's grammar is simple enough to do this.
 2019-09-22 17:18:28 -05:00
Calvin Rose 8e427317cd Add mean function to boot.janet 
Update changelog.
 2019-09-19 21:21:14 -05:00

Calvin Rose 060d11e4c2 Add Q and q formatters to buffer/format. 
These are similar to P and p, but print values
on a single line for a much more compact version.

Calvin Rose 44e752d737 Add shorthand function literals to janet. 
These are similar to the function literals from Clojure
(also Fennel), and should make short functions for maps, filters, etc.
easier to write.
 2019-08-04 12:25:52 -05:00
Calvin Rose 02ce3031e9 Fix comp case with arity of exactly 5. 2019-08-03 14:53:14 -05:00

Calvin Rose dfe00fee94 Building standalone binaries on linux working. 
Mostly changes to cook and jpm. Also some
code for file associations in the windows installer, and
adding the :linux value from os/which (instead of just :posix).
 2019-07-26 22:43:54 -05:00
Calvin Rose a0e98b9aa8 Deprecate process/args and add use macro. 
Use is a shorthand for (import module :prefix "").
process/args has been replaced by (dyn :args) at
the top level.
 2019-07-20 16:57:07 -05:00
Calvin Rose 0d3986abbb Update cook and add an install test. 2019-07-19 19:40:51 -05:00
Calvin Rose e528b86a2a Ensure no carriage returns end up in doc strings. 2019-07-12 09:14:37 -04:00
Calvin Rose a7f3d3436f Update CHANGELOG.md 
Also change `with-resource` to `with`.
 2019-06-24 22:02:37 -04:00
Calvin Rose b8032ec61d Add propagate function and opcode 
This allows better stacktraces when manually intercepting
signals to clean up resources. Also allows functionality
from Common Lisp's unwind-protect, such as calling cleanup code
while unwindinding the stack, restarting on certain signals, and
just in general having more control over signal and signal propagation.

Also fix a bug encountered while implementing with-resource in the
compiler. Desturcturing arguments that were not the last argument
would often result in bad code generation, as slots used to destructure
the earlier arguments would invalidate the later parameters. This is
fixed by allocating all named parameters before doing any destructuring.
 2019-06-24 12:44:13 -04:00
Calvin Rose cf05ff610f Add some fixes for serializing complex grammars. 2019-06-19 23:23:27 -04:00
Calvin Rose 7eb78c8028 Load jimage files before janet source files. 
This should allow precompiled files to be placed
right next to the source files in the file system with
the expected behavior.
 2019-06-19 20:18:44 -04:00
Calvin Rose fc46030e7d Add options to not include docstrings in binary. 
This lets us build a smaller binary. The minimal tested
binary on x86-64 (with -Os, -s, and all options that shrink binary size
        turned on) is about 240 kB.
 2019-06-19 19:43:38 -04:00
Calvin Rose 0102a72538 Update module/paths for saner defaults. 
Relative imports will only check the paths
directly concerning relative imports.
 2019-06-19 09:01:21 -04:00
Calvin Rose 264c5bc02b Change default module/path. 
Disallow loading directly with extension to be more
consistent and keep things simpler.
 2019-06-19 00:34:15 -04:00
Calvin Rose 9ba8728176 Update module system. 
Add relative imports and path normalization. This should
help towards a more composable build/dependency system.

Also change external unification identifier in match macro
to @. This means we can more easily match symbol literals.
 2019-06-10 14:00:51 -04:00
Calvin Rose 6225f8d334 Fix defn docstring typo. 2019-06-09 09:18:16 -04:00
Calvin Rose d9a4ef05ac Update docstring format. 
Also add :p flag to fiber/new, change implemntation of with-dyns, and
make meson build install static library by default.

Move all installed libraries into auxlib.
Move all installed executable scripts into auxbin.
 2019-06-01 10:38:28 -04:00
Calvin Rose db55277b58 Work on windows installer. 
We will probably shift to NSIS as the default
installation method for windows. Shipping around a
single binary just doesn't cut it if we want to be able
to reliably use tools like `jpm` to build things.
 2019-05-28 20:45:39 -04:00
Calvin Rose 1696de233c Add jpm tool, based on cook. 
Modify cook as well.

Try to simplify module/paths back to how it used to be.
 2019-05-25 17:27:56 -04:00
Calvin Rose 840610facf Add urlloader example. 
Demonstrate loading files from URL.
 2019-05-25 17:10:25 -04:00
Calvin Rose 0280deccae Allow filters on templates in module/paths 
This lets us make loaders depend on file suffixes, which
lets us more efficiently use full paths.
 2019-05-25 16:13:02 -04:00
Calvin Rose b5e6c0b8fc Address #109 
Make repl work when default chunks not supplied.
 2019-05-22 23:56:59 -04:00
Adam Schwalm f444bd25ef Add a 'compile-only' flag to the command line 
This allows syntax checkers like the emacs 'flycheck-mode' to check
the source without side effects.
 2019-05-19 12:55:28 -05:00
Calvin Rose 7054e878fb Add module/loaders for custom file types. 
This will allow other languages/DSLs to very easily
integrate with Janet.
 2019-05-16 12:05:40 -04:00
Calvin Rose dde5351d11 Small changes to some doc strings. 2019-05-16 11:43:21 -04:00
Calvin Rose 7d49e3e6f1 Add unification to match macro. 
Using a quote on a symbol prevents the match
macro from trying to create a binding to it, and
instead tells it that we are binding to a symbol
that is already in scope.
 2019-05-16 10:05:54 -04:00
Calvin Rose f35b5765d6 Set module/*headerpath* during bootstrap 
Cook also uses module/*headerpath* for finding headers
rather than using module/*syspath*.
 2019-05-15 10:49:16 -04:00
Calvin Rose f647ac5631 Address #95 
A very minimal code change made partition take strings.
 2019-05-15 00:04:25 -04:00

Partially adress issue #93
 2019-05-14 11:05:19 -04:00
Calvin Rose 232ea22dc5 Add string/triml, string/trimr, and string/trim. 2019-05-10 16:09:49 -04:00
Calvin Rose 3388acd2db Add dofile function. 
Abstracts the actually running of a file from
the require function, so a file can be easily
evaluated without being cached.
 2019-05-10 10:19:51 -04:00
Calvin Rose 88b8418253 Add simple tracing functionality to VM. 
Also disable debugger for normal errors.
 2019-05-04 15:05:00 -04:00
Calvin Rose 1cfc7b3b0d Add preliminary debugger to default repl. 
Also upddate colors, and fix formatting.
 2019-05-02 17:11:30 -04:00
Calvin Rose 25a93ac4a6 Fix loop :iterate. 2019-04-28 00:34:32 -04:00
Calvin Rose 20e94adb61 Update documentation for update function. 2019-04-21 15:44:03 -04:00
Calvin Rose d1eca1cf52 Add all-dynamics to list current dynamic bindings. 2019-04-17 09:47:33 -04:00
Calvin Rose 7918add47d Allow dynamically setting output for printers 
Some functions like print and debug/stacktrace print
to a file, usually stdout. This file can now be optionally set
via a dynamic variable.
 2019-04-16 21:44:19 -04:00
Calvin Rose 513d551df6 Move print in source code to io module. 
print now reads the dynamic binding for :out
when choosing where to write to.
 2019-04-16 19:10:01 -04:00
Calvin Rose 2d7df6b78e Many changes for adding dynamic (fiber-level) scope. 
- Allow passing a table to fibers, which make fiber level scope easier.
- Add fiber/getenv, fiber/setenv, dyn, and setdyn
- Remove meta, *env*, and *doc-width*
- Some functions changed dignatures, and no longer take an env
 2019-04-16 15:41:45 -04:00
Calvin Rose 5287007cd6 Fix typo in comment. 2019-04-09 09:05:47 -04:00
Calvin Rose e5a56174e2 Switch fexists to use os/stat when available. 
When os/stat is not available, we first
try to read one byte from the file before
saying it is good. If that fails, it is not
a file that we can read from so it counts as not found.
 2019-04-09 09:01:52 -04:00
Calvin Rose 6c68c7a35f Address issue #78 
(file/open path :r+) should help. On windows, result
is unknown as of now.
 2019-04-09 08:38:56 -04:00
Calvin Rose fa1c5c85b5 Remove no-capture mode in pegs. 
Some peg grammars could not capture values based on their position in a
larger grammar. This is a design limitation inheritted from LPeg, but no
longer needed as the replace mode is superseded by the accumulator mode,
which is more general if slightly harder to use.
 2019-04-06 11:38:00 -04:00
Calvin Rose 7d48e7fd1f Remove some extra search paths. 2019-04-01 14:07:13 -04:00
Calvin Rose 0063e3a69d Fix module path typo. 2019-04-01 13:48:30 -04:00
Calvin Rose 082639319e Add colors to repl and string/format. 
This makes the repl look nicer using ANSI
color codes, which are widely supported. The codes
can also be turned off via the -m flag.
 2019-03-24 15:00:22 -04:00
Calvin Rose 7f1b5d4d70 Merge core.janet into boot.janet 
This simplifies the build machinery a bit.
core.janet is never actually included in the final
binary, it is just used to generate an image file.
 2019-03-22 18:34:50 -04:00
Calvin Rose 25aa7a26c5 Add experimental meson build. 
Should help with IDE integration.
 2019-03-22 18:07:10 -04:00
Calvin Rose cb002e7b84 Update generating tools to produce stylish code. 
Really small whitespace changes in generated code.
 2019-02-19 21:28:22 -05:00
Calvin Rose ed72dcf82d Rename the header <janet/janet.h> to <janet.h> 
Makes it easier to use and remember, and makes the
variable `module/*headerpath*` make more sense.
 2019-02-18 20:13:35 -05:00
Calvin Rose 6d5ff43de7 Make amalg build cleaner. 
Don't pull in a global header <janet/janet.h> unless we need to.
 2019-02-16 23:33:24 -05:00
Calvin Rose fe27df528c Boot core library from image rather than source 
This should speed up start time and reduce malloc/free
usage to about 15% of what is what previously for startup.
The current cost is slightly larger binary as the representaion
of the image is currently less compact than source code.
 2019-02-08 00:44:30 -05:00
