Class orion.editor.TextMateStyler

Extends orion.editor.AbstractStyler.
A styler that knows how to apply a subset of the TextMate grammar format to style a line.

Styling from a grammar:

Each scope name given in the grammar is converted to an array of CSS class names. For example a region of text with scope keyword.control.php will be assigned the CSS classes
keyword, keyword-control, keyword-control-php

A CSS file can give rules matching any of these class names to provide generic or more specific styling. For example,

.keyword { font-color: blue; }

colors all keywords blue, while

.keyword-control-php { font-weight: bold; }

bolds only PHP control keywords.

This is useful when using grammars that adhere to TextMate's scope name conventions, as a single CSS rule can provide consistent styling to similar constructs across different languages.

Top-level grammar constructs:

patterns, repository (with limitations, see "Other Features") are supported.
scopeName, firstLineMatch, foldingStartMarker, foldingStopMarker are not supported.
fileTypes is not supported. When using the Orion service registry, the "orion.edit.highlighter" service serves a similar purpose.

Regular expression constructs:

match patterns are supported.
begin .. end patterns are supported.
The "extended" regex forms (?x) and (?x:...) are supported, but only when they apply to the entire regex pattern.
Matching is done using native JavaScript RegExps. As a result, many features of the Oniguruma regex engine used by TextMate are not supported. Unsupported features include:
- Named captures
- Setting flags inside subgroups (eg. (?i:a)b)
- Lookbehind and negative lookbehind
- Subexpression call
- etc.

Scope-assignment constructs:

captures, beginCaptures, endCaptures are supported.
name and contentName are supported.

Other features:

applyEndPatternLast is supported.
include is supported, but only when it references a rule in the current grammar's repository. Including $self, $base, or rule.from.another.grammar is not supported.
