CodeMirror PCRE mode
This is a CodeMirror mode that brings syntax highlighting for Perl Compatible Regular Expressions (PCRE).
How to use
Basic use
Load pcre.js
and pcre.css
at adequate locations in your HTML structure.
Mention mode: 'pcre'
when creating your CodeMirror instance.
Configuration
codemirror-mode-pcre supports extended mode (x
flag) and actually enables it by default. This can be turned off by passing extended: false
when creating the CodeMirror instance.
Theming
This mode does not leverage CodeMirror's default tokens (they are not exactly fitted for regular expressions). Consequently, if you use a theme other than the default one, you will likely want to write your own pcre.css
file.
Breaking change: starting with version 2.0.0, the cm-end-group
style is no longer supported and should no longer be used. It is replaced with cm-start-group
.
Nesting
codemirror-mode-pcre can be nested within another mode, i.e. it can highlight regular expressions for another mode. This requires adjusting the other mode though. See the demo page for an example of such nesting.
Non-features
codemirror-mode-pcre does not offer:
- completion (e.g. suggesting POSIX class names or script names for \p
and \P
);
- tooltips reflecting what the various parts of an expression actually mean.
Those may come in the future though.
License
Like the PCRE library, this mode is released under the 3-clause BSD license.
