find-token-in-code v1.0.0

find-token-in-code

find a token in a code.

(including exclude of string, comment template etc) based on find-macthing-bracket npm package

And works for simple structure recognition in both JS Ts and Cs

    const code = `
    // test
    const foo = "test";
    let test1 = 42
    let test = true
    `;
    const position = matchToken(code, 'test');
    // position = 64 (the 'test' in 'let test = true')
    const reg_position = matchToken(code, /test\d*/);
    // reg_position = 45 (the 'test' in 'let test1 = 42')

complex example:

    const code = "var foo = `some ${test()}`; function test(){return 0}"
    const position = matchToken(code, 'test');
    // position = 37 (the 'test' in `some ${test()}` are not alloew by default on curly;)
    // default allowed parens are  [undefined,brackets.curly]

    const position = matchToken(code, 'test',[undefined,brackets.curly,brackets.escapeJsTemaple]);
    // position = 18 (the 'test' in `some ${test()}`;)

Allowed parent (Matching bracket): | name | start | end | node | |:-----|:-----:|:---:|:-----| | undefeined | | | This is global scope | | lineComment | // | \n | | | multilineComment | / | / | | | multilineComment | / | / | | | angle | < | > | | | peparentheses | ( | ) | | | square | | | | | curly | { | } | | | double | " | " | | | single | ' | ' | | | jsTemplate | ` | ` | | | cSharpTemplate | $" | " | | | escapeJsTemaple | ${ | } | only in jsTemplate | | inCSharpTemaple | { | } | only in cSharpTemplate |
