    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.

    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;
    • support for fancy module loaders.

    Those may come in the future though.

    License

    Like the PCRE library, this mode is released under the 3-clause BSD license.
