Parsefunc

Parse the exports functions in a file or a module, useful for used with editor plugin (like the vim plugin unite-js-func).

The backend of file parsing is done by acorn

Beside top level functions, it can understands the exported functions like:

// assigned to this
this.xyz = function(){}
// assigned to prototype
Emitter.prototype.on = function(){}
// assigned to module.exports
module.exports = function(){}
// assigned to exports
exports.dosomething = function(){}

The browser field in package.json(used for name alias) used by webpack and browserify is also considered.

Install

npm install -g parsefunc

Example

# parse files
parsefunc fileA fileB

# parse files required by fileA
parsefunc -r fileA

# parse files of a module
parsefunc -m module

# parse modules used by a file
parsefunc -m ./fileA

# parse files of current module
parsefunc -m this

# parse files of all modules in dependencies of package.json
parsefunc -a

# parse from stdin
cat index.js | parsefunc

The output would looks like:

lib/index.js:9:exports.parse
lib/index.js:14:exports.parseFiles
lib/index.js:36:exports.parseModule
lib/index.js:73:exports.parseRelative
lib/util.js:5:checkState
lib/util.js:24:exports.parse
lib/util.js:86:exports.suffixFile
