title: Saving via a Minimal Web Server
type: text/vnd.tiddlywiki
A local server for TiddlyWiki5 that saves and backups wikis, inspired by
[[tw5-server.rb | https://gist.github.com/jimfoltz/ee791c1bdd30ce137bc23cce826096da]].
tw5-server provides features of:
* Server for TiddlyWiki5, as well as other files (e.g. images used in TW5 `[img[images/*.png]]`);
* Easy to save wiki via browsers;
* Backup wiki in compress format (.gz), to save disk space;
* Auto clean backups: keep one newest per previous month, keep all backups in current month.
* Upload files/images to server, for use in tiddlywiki as external links.
* Offer binary executable for Linux, macos and windows.
Download executable script and binary at the github.com [[tw5-server|https://github.com/hffqyd/tw5-server]].
! Usage
```bash
# python script:
python tw5-server.py -p 8000 -d ./ -b backup_dir
# binary file:
tw5server -a:192.168.0.10 -p:8000 -d:./ -b:backup
-h usage help
-a address, defautl localhost
-p port, default 8000
-d directory to servering, default `current dir`
-b backup directory name, default `backup`
-l log saving messages to stdout
Backups auto-clean strategy:
Keep all backups in current month, keep only the newest one for previous months.
```
In Unix/Linux, just excute `./tw5-server.py` (with `chmod +x tw5-server.py`).
Then go to http://localhost:8000 (or other address:port specified in command) in your web browser, and click on your wiki html file.

! $action-listops widget vs. $action-setfield widget
!! Comparison to [[ActionSetFieldWidget]]
The ActionSetFieldWidget replaces a field's value using `$field`/`$value` attributes. A single ActionSetFieldWidget can be used to set any number of fields by using attributes not starting with $.
In general, ActionSetFieldWidget is better for setting multiple fields at once and for replacing the value of a field, which can also be a list. The ActionListopsWidget is better for modifying a list field based on the existing list and for using a [[Filter Expression]] to derive the value of the field.
The ActionListopsWidget replaces or modifies a single field's value. The new value is generated using filters.
The ~ActionSetFieldWidget sets the value of a field using `$field` and `$value` attribute pairs or attributes that do not start with a `$`. A single ~ActionSetFieldWidget can be used to set any number of fields of a single tiddler.
The following two examples are functionally equivalent:
The ~ActionListopsWidget replaces or modifies a single field's value using filter expressions.
The following widgets are functionally equivalent:
```
<$action-setfield $field="myfield" $value="abc 123"/>
```
```
<$action-setfield myfield="abc 123"/>
<$action-listops $field="myfield" $filter="abc 123"/>
```
Note that <<.value "abc 123">> in the first two cases is a literal string that is assigned to the field <<.field myfield>>, but in the third case a filter expression which evaluates to the same string.
In general, ActionSetFieldWidget is better for setting multiple fields at once and for replacing a field's value. The ActionListopsWidget is better for modifying a field based on the field's existing value and for using a [[Filter Expression]] to derive the value.

In some cases, there may occur unexpected de-duplication of lists.
! Examples
!!! Assignments to the <<.field list>> field
In this example we shall populate and then clear a list in an ordinary field (myfield) of this tiddler (the default.)
When assigning filter results to the <<.field list>> field (default), the generated list is automatically de-duplicated, so
```
<$action-listops $filter="[[1]] :and[[1]]"/>
```
will result in the <<.field list>> field of the current tiddler containing the string <<.value 1>>, but not <<.value "1 1">>.
!!! Input to the subfilter expression
The input to the subfilter expression in the `$subfilter` attribute is also de-duplicated. If you rely on lists containing duplicates, consider using this alternative using the `$filter` attribute:
<$macrocall $name='wikitext-example-without-html'
src="""<$button>
<$action-listops $field="myfield" $subfilter="efg hlm pqr"/>
Populate 'myfield'
</$button>
<$button>
<$action-listops $field="myfield" $subfilter="abc xyz"/>
Append More Items
</$button>
<$button>
<$action-listops $field="myfield" $subfilter="-abc -hlm"/>
Remove Items
</$button>
<$button>
<$action-listops $field="myfield" $filter="[[]]"/>
Clear 'myfield'
<$action-listops $field="myfield" $filter="[enlist:raw{!!myfield}] :all[[abc]]" />
Add 'abc' to 'myfield'
</$button>
<$list filter="[list[!!myfield]]">
<$list filter="[enlist:raw{!!myfield}]" template="$:/core/ui/ListItemTemplate" />
"""/>
The [[enlist Operator]] with `raw` suffix will enlist the list saved in <<.field myfield>> of the current tiddler without de-duplication, while e.g. the [[list Operator]] will always de-duplicate. The widget then adds the item <<.value abc>> -- whether or not it is already included in the list -- and replaces the original list in <<.field myfield>>.

! Introduction
A number of filters are used to manipulate lists.
Some filters are designed to move items from the tail of the list and insert them at specified locations in the list, e.g. [[putafter|putafter Operator]] or [[putbefore|putbefore Operator]]. Items are often appended to the list before using these filters. In general, these filters accept a suffix specifying the number of items to move (default to 1.)
Some filters are designed to either add or remove from the list, a selected range of items from an array, e.g. [[append|append Operator]] or [[remove|remove Operator]]. These filters are best used with a reference to an array, stored in a field or data index elsewhere in the wiki (they may be used with a simple list of items, provided the items do not include white space.) In general, these filters accept a suffix specifying the number of items to move (default to All.)

title: The Extended Listops Filters
! Introduction
A number of extended filters are necessary to manipulate lists.
The first set of filters are designed to move items from the tail of the list and insert them at specified locations in the list. Items are often appended to the list before using these filters. In general, these filters accept a suffix specifying the number of items to move (default to 1.)
A second set of filters are designed to either add or remove from the list, a selected range of items from an array. These filters are best used with a reference to an array, stored in a field or data index elsewhere in the wiki (they may be used with a simple list of items, provided the items do not include white space.) In general, these filters accept a suffix specifying the number of items to move (default to All.)
! Examples
In this example we shall populate the '~DataIndex' index of the tiddler '~MyData' with the names of the days of the week, then clear this list.
<$macrocall $name='wikitext-example-without-html'
src="""<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $filter="[list[Days of the Week]]"/>
Get days-of-the-week
</$button>
<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $filter="[[]]"/>
Clear
</$button>
{{ListopsData}}"""/>
---
In this example we shall slice the populated list from the 'DaysOfTheWeek' index of the tiddler '~MyData' in order to insert items before and after a marker item (Wednesday) that are first appended to the list.
<$macrocall $name='wikitext-example-without-html'
src="""<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $subfilter="one two +[putbefore:2[Wednesday]]"/>
Put 2 Items Before Wednesday
</$button>
<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $subfilter="four five +[putafter:2[Wednesday]] three +[putbefore[Wednesday]]"/>
Put One Item Before & Two Items After Wednesday
</$button>
{{ListopsData}}"""/>
---
In this example we shall slice the populated list from the 'DaysOfTheWeek' index of the tiddler '~MyData' in order to replace the marker item (Wednesday) with items which are first appended to the list. We shall then move 3 items to the head of the list which have first been appended to the list from referenced fields.
<$macrocall $name='wikitext-example-without-html'
src="""<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $subfilter="[[---o]] [[o---]] +[replace:2{!!marker}]"/>

---
In this example we shall slice the populated list from the 'DaysOfTheWeek' index of the tiddler '~MyData' in order to append to the truncated list, items from a referenced field. We shall then remove the first two of the items added.

<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $subfilter="+[allbefore:include[Wednesday]] +[prepend{!!list}]"/>

</$button>
<$button>
<$action-listops $tiddler="ListopsData" $index="DataIndex" $subfilter="+[remove:2{!!list}]"/>

!! Bold vs Strong
In TW we use the term "bold" instead of "strong" because most users are used to it. ... The rendering process converts our "bold text" into the STRONG HTML element.
>The `<strong>` element is for content that is of greater importance, while the `<b>` element is used to draw attention to text without indicating that it's more important.
>https://developer.mozilla.org/en-US/docs/Web/HTML/Element/strong#b_vs._strong
!! Underline vs. Underscore
>Use underline to describe text formatting that puts a line under the characters. Use underscore to refer to the underscore character ( _ ).
>https://learn.microsoft.com/en-us/style-guide/a-z-word-list-term-collections/u/underline-vs-underscore
!! Emphasis vs Italics
>The `<em>` element represents stress emphasis of its contents, while the `<i>` element represents text that is set off from the normal prose, such as a foreign word, fictional character thoughts, or when the text refers to the definition of a word instead of representing its semantic meaning. (The title of a work, such as the name of a book or movie, should use `<cite>`.)

!! Summary
Use HTML entities to enter characters that cannot easily be typed on an ordinary keyboard. They take the form of an ampersand (`&`), an identifying string, and a terminating semi-colon (`;`), e.g. `&amp;` for the ''&'' character.
!! Markup
```
The value of Tiddlers&trade; cannot even be expressed in &pound;, &euro; or &dollar;.
```
''Displays as:''
The value of Tiddlers&trade; cannot even be expressed in &pound;, &euro; or &dollar;.

caption: Styles and Classes
You can use this construction to cause the wrapped content to be assigned specified CSS classes or styles:
Content can be wrapped in `@@`double at signs`@@` to apply specified CSS styles or classes to it. There are multiple ways to use this syntax, as presented below.
<<wikitext-example src:"@@.myStyle
* List One
* List Two
Inline content wrapped in `@@`double at signs`@@` without specifying style or class will be assigned the `.tc-inline-style` and displayed as highlighted text. The foreground and background colours of the highlighted text are defined as `highlight-background` and `highlight-foreground` in the current palette.
<<wikitext-example src:"@@some highlighted text@@">>
Style attributes, e.g. `color`, each followed by `;` semicolon can be introduced immediately after the opening `@@`.
<<wikitext-example src:"@@color:steelblue;background-color:lightcyan;some styled text@@">>
Similarly a style can be applied to a multiline content:
<<wikitext-example src:"@@background-color:lightcyan;
* Item one
* Item two
@@
">>
Similar syntax is used to assign styles. For example:
A class may be applied to a multiline content only:
<<wikitext-example src:"@@background-color:red;
* List One
* List Two
@@
">>
Multiple styles and classes can be mixed. For example:
<<wikitext-example src:"@@.tc-tiddler-frame
@@width:400px;
Some text
<<wikitext-example src:"@@.tc-double-spaced-list
* Item one
* Item two
@@">>
Multiple classes and styles can be used together:
<<wikitext-example src:"@@.tc-double-spaced-list
@@width:400px;background-color:lightcyan;
* Item one
* Item two
@@
">>
