+The difference algorithm operates in character mode by default. This produces the most detailed diff possible. In `words` mode, each word in the input text is transformed into a meta-character, upon which the algorithm then operates. In the default character mode, the filter would find two patches between "ActionWidget" and "Action-Widgets" (the hyphen and the plural s), while in `words` mode, the whole word is found to be changed. In `lines` mode, the meta-character is formed from the whole line, delimited by newline characters, and is found to be changed independent of the number of changes within the line.

+The different modes influence the result when the patches are applied to texts other than the original, as well as the runtime.

+
+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.

+!!! 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
+

+
+!!! 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:

+!! 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>`.)

+type: text/vnd.tiddlywiki
+
+!! 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. `&` for the ''&'' character.
+
+!! Markup
+
+```
+The value of Tiddlers™ cannot even be expressed in £, € or $.

+
+''Displays as:''
+
+The value of Tiddlers™ cannot even be expressed in £, € or $.
+
+!! Entity References
+
+Comprehensive lists of html entities can be found at...

+* [[Mozilla Developer Network -- Entities|https://developer.mozilla.org/en-US/docs/Glossary/Entity]]
+
+* [[HTML Spec official list -- Entities|https://html.spec.whatwg.org/multipage/named-characters.html#named-character-references]]

-You can use this construction to cause the wrapped content to be assigned specified CSS classes or styles:

-<<wikitext-example src:"@@.myStyle

+Inline content wrapped in `@@`double at signs`@@` without specifying style or class will be assigned the `.tc-inline-style` and displayed as highlighted text.
