A NodeJS REPL with ShellJS loaded by default
MIT License
A node REPL with ShellJS loaded by default.
This was inspired by (and forked from) n_.
Give it a star on Github
$ npm install -g n_shell
Invoking n_shell
starts a node REPL with ShellJS required globally, with
shell-like output:
bash $ n_shell
shelljs $ ls()
LICENSE
README.md
bin
node_modules
package.json
src
tmp
shelljs $ pwd()
/path/to/dir
shelljs/global
No problem:
bash $ n_shell --no_global
shelljs $ typeof ls // not in the global namespace
'undefined'
shelljs $ shell.ls() // uses 'shell' prefix
LICENSE
README.md
bin
node_modules
package.json
src
tmp
shelljs $ shell.pwd()
/path/to/dir
You're covered:
bash $ n_shell --no_global=$
shelljs $ $.ls() // now uses '$' as the prefix
LICENSE

node_modules
package.json

tmp
shelljs $ $.pwd()

Just install that version locally (npm install shelljs
) and start up
n_shell
with the --path
option:
bash $ n_shell --path=node_modules/shelljs
shelljs $
bash $ n_shell --noinspect
shelljs $ ls()

This supports any command that ShellJS supports. It also adds some extra commands, for convenience. So far, this adds:
shell.clear()
(fromshell.open()
(fromshell.sleep()
(from--global
: Start a node REPL with the equivalent ofrequire('shelljs/global')
. This is the default behavior.--no_global [PREFIX]
, --local [PREFIX]
, -n [PREFIX]
: Start a node REPLvar PREFIX = require('shelljs')
. PREFIX
defaultsshell
, if not specified.--use_strict
: enforce strict mode (default is false)--prompt <FORMAT>
: use this format to generate the REPL prompt. Default isshelljs %v%l $
"
%%
: a literal %
sign%v
: show the current version (from package.json
)%l
: show [local]
if this is using a local version of ShellJS--noinspect
: disable the default --inspect
behavior. This provides--path=path/to/shelljs/
: the argument should be a path to a folder--inspect
(default): an experimental switch to add a .inspect()
method toshell.pwd
and shell.ls
. RecommendedSimilarly to n_
, n_shell
stores REPL history under ~/.n_shell_history
.
