We now use webpack instead of SystemJS, effectively bundling modules into one file (plus commons chunks) for every entry point. This results in a much smaller extension size (almost half). Furthermore we use yarn/npm even for extension run-time dependencies. This relieves us from manually vendoring and building dependencies. It's also easier to understand for new developers familiar with node.
which
Like the unix which
utility.
Finds the first instance of a specified executable in the PATH
environment variable. Does not cache the results, so hash -r
is not
needed when the PATH changes.
USAGE
var which = require('which')
// async usage
which('node', function (er, resolvedPath) {
// er is returned if no "node" is found on the PATH
// if it is found, then the absolute path to the exec is returned
})
// sync usage
// throws if not found
var resolved = which.sync('node')
// Pass options to override the PATH and PATHEXT environment vars.
which('node', { path: someOtherPath }, function (er, resolved) {
if (er)
throw er
console.log('found at %j', resolved)
})
CLI USAGE
Same as the BSD which(1)
binary.
usage: which [-as] program ...
OPTIONS
You may pass an options object as the second argument.
path
: Use instead of thePATH
environment variable.pathExt
: Use instead of thePATHEXT
environment variable.all
: Return all matches, instead of just the first one. Note that this means the function returns an array of strings instead of a single string.
