usage
replem [options] [<pkg>[:<alias>]]...
--repl require a custom repl
-v, --verbose enable verbose output
-h, --help displays help

arguments
Uses npm install
internally, so
similar types of arguments are accepted.
For example:
- Install a specific version:
replem lodash@3.0.0
- Install a module from GitHub:
replem githubname/reponame#commit
By postfixing module's name with :<alias>
you can set an alias for a
module. Module's exports will be available under this name.
$ replem ramda:RInstalled into REPL context: - ramda@0.17.1 as R> R.inc // 2
With a bang (!
) after everything, all module's properties will be directly
available in context:
$ replem ramda!Installed into REPL context: - ramda@0.17.1 as ramda> reduce === ramda.reducetrue
custom repl
To use a custom repl, install it to ~/.replem/node_modules
first:
$ npm install --prefix ~/.replem coffee-script$ replem --repl coffee-script/repl lodash>
requiring from inside installed modules
The REPL context is provided with the function replem.require()
that can be
used to require from under ~/.replem/node_modules
.
caveats
- Multiple versions of the same module cannot be used concurrently.
