VSCode TextMate
An interpreter for grammar files as defined by TextMate. Supports loading grammar files from JSON or PLIST format. Cross - grammar injections are currently not supported.
Installing
npm install vscode-textmate
Using
var Registry = require('vscode-textmate').Registry;
var registry = new Registry();
var grammar = registry.loadGrammarFromPathSync('./javascript.tmbundle/Syntaxes/JavaScript.plist');
var lineTokens = grammar.tokenizeLine('function add(a,b) { return a+b; }');
for (var i = 0; i < lineTokens.tokens.length; i++) {
var token = lineTokens.tokens[i];
console.log('Token from ' + token.startIndex + ' to ' + token.endIndex + ' with scopes ' + token.scopes);
}
Using asynchronously
Sometimes, it is necessary to manage the list of known grammars outside of vscode-textmate
. The sample below shows how this works:
var Registry = require('vscode-textmate').Registry;
var registry = new Registry({
getFilePath: function (scopeName) {
// Return here the path to the grammar file for `scopeName`
if (scopeName === 'source.js') {
return './javascript.tmbundle/Syntaxes/JavaScript.plist';
}
return null;
}
});
// Load the JavaScript grammar and any other grammars included by it async.
registry.loadGrammar('source.js', function(err, grammar) {
if (err) {
console.error(err);
return;
}
// at this point `grammar` is available...
});
Tokenizing multiple lines
To tokenize multiple lines, you must pass in the previous returned ruleStack
.
var ruleStack = null;
for (var i = 0; i < lines.length; i++) {
var r = grammar.tokenizeLine(lines[i], ruleStack);
console.log('Line: #' + i + ', tokens: ' + r.tokens);
ruleStack = r.ruleStack;
}
