argv-formatter
Bizarro minimist: transform an options object into into a process.argv
-like array. Helpful for using child_process
and passing complex arguments more easily.
Setup
$ npm install --save argv-formatter
API
formatter.format(object)
-> Array
Accepts an object
of containing options and arguments and returns an array of arguments.
- options with a value of
true
will be included with a flag only ({R: true}
->['-R']
) - options that are falsey will be removed
- all values will be stringified, (
{D: new Date(0)}
->['-D', 'Thurs Jan 1 1970...']
) - arguments can be passed under the
_
key as a value or array of values
Examples
To generate arguments to a git log
command for printing the short hashes of commits that have changed our test files:
var args = formatter;console; // --format=%h ./test/*
git-log-parser uses this to spawn a git
process:
var spawn = spawn;var formatter = ;var args = formatter;var child = ;
