Package Exports

vscode-textmate

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (vscode-textmate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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 vsctm = require('vscode-textmate');
var grammarPaths = {
    'source.js': './javascript.tmbundle/Syntaxes/JavaScript.plist'
};

var registry = new vsctm.Registry({
    loadGrammar: function (scopeName) {
        var path = grammarPaths[scopeName];
        if (path) {
            return new Promise((c,e) => {
                fs.readFile(path, (error, content) => {
                    if (error) {
                        e(error);
                    } else {
                        var rawGrammar = vsctm.parseRawGrammar(content.toString(), path);
                        c(rawGrammar);
                    }
                });
            });
        }
        return null;
    }
});

// Load the JavaScript grammar and any other grammars included by it async.
registry.loadGrammar('source.js').then(grammar => {
    // at this point `grammar` is available...
    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);
    }
});

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;
}
