What we want

http://en.wikipedia.org/wiki/Comparison_of_JavaScript-based_source_code_editors
With realtime Syntax highlighting
Compatible with our License
Support for PHP, JavaScript, HTML, CSS, MySQL, Smarty, YAML so we can Dogfood within Tiki.
Support for other popular languages (Python, Java, etc.)
Possible to add syntaxes, such as Tiki markup so we can do something like WikiWizard
Ideally will open the door to Web commits
To find an open source project happy to be integrated in Tiki and that could help us.

Wishes

Bugs

2013-01-31: 10.x Can't paste text (that is in my clipboard) with Android browser in comment box of a tracker item on dev.tiki.org. Workaround: Toggle highlighter
2012-09-29: Doing CTRL-F to find test on a page will not find all results. Workaround: Toggle highlighter
- Try here: http://profiles.tiki.org/tiki-editpage.php?page=CartoGraf and find "attach". With CodeMirror, there are 2 results. If I click "Toggle Highlighter" to turn it off, I now have 7 results.
  - Marijn Haverbeke on the mailing list wrote:
    
    This is expected behavior. For performance reasons, CodeMirror only
    renders the part of the document that is visible. Thus, the browser won't search through the rest.
    
    If this is a big issue for you, you can use the viewportMargin option that's in the v3 branch
    (http://codemirror.net/3/doc/manual.html#option_viewportMargin), but don't do that if you want big documents to be fast.
    - 2013-11-17: still an issue in 12.x with CodeMirror 3.x
Fullscreen needs to auto-detect buttons that are found below on the page if any (like wiki: save, preview, etc) and add them if not, make sure if buttons are hidden, they are not added.
http://irc.tiki.org/irclogger_log/tikiwiki?date=2012-09-30,Sun&sel=204#l200
When I edit a Wiki page and press Home or End keys, the cursor jumps not to the start/end of line, but the start/end of paragraph.

Feedback from 8.x

False positives
- Strike trough syntax here: http://dev.tiki.org/Semi-automatic+merging+period
- PluginCode is missing a way to have colors "none" (ex.: when it doesn't have a syntax like sql)

Feedback from 7.x experimental

Robert & Marc

7.x

~~PluginCode: CodeMirror is doubling up~~ (seems good to me - jb 110714)
~~Upgrade 7.x to CodeMirror 1.0 to get bug fixes~~ (done jb 110714)

Trunk

~~Upgrade trunk to CodeMirror2 to get new goodies~~
- Use YAML parser for profiles.tiki.org
  - This works but you need to use the yaml param for each plugin
    - A perfect example for Override default params for plugins
- the 8 .js files should be minified
- Make strings translatable

GeSHi

Not realtime and since it's GPL, we can't bundle in Tiki.
http://qbnz.com/highlighter/

Plan is to replace the partial integration with one of the others below for Tiki 7

SyntaxHighlighter

Realtime? License is OK.
http://alexgorbatchev.com/SyntaxHighlighter/

No Smarty or YAML (3rd party add-on "brush" available for YAML)
Seems to be the "market" leader, so will probably be maintained for longer
Seems a bit slow on some syntaxes

EditArea

Realtime: yes License is OK.
http://www.cdolivet.com/index.php?page=editArea

More of an editor than a highlighter (so might be good for our wiki editor, if it handled Tiki markup)
No Smarty or YAML
Seems a bit klunky and not happy in Safari

JQuery Syntax Highlighter

Realtime: Yes License OK (MIT & GPL)
http://webcodingstudio.com/blog/jquery-syntax-highlight-plugin

Seems much faster and lighter than SyntaxHighlighter (uses jQuery)
No SQL, Smarty or YAML (the could be added maybe?)

CodePress
