repl(1) -- sometimes you need a repl

====================================



`repl` is an interactive program which tenderly wraps another,

non-interactive program.



For example:



    $ repl redis-cli -p 6665

    >> set name chris

    OK

    >> get name

    chris

    >> info

    redis_version:1.000

    uptime_in_seconds:182991

    uptime_in_days:2

    .. etc ..



Or:



    $ repl gem

    >> --version

    1.3.5

    >> search yajl



    *** LOCAL GEMS ***



    yajl-ruby (0.6.7)

    >> search yajl -r



    *** REMOTE GEMS ***



    brianmario-yajl-ruby (0.6.3)

    filipegiusti-yajl-ruby (0.6.4)

    jdg-yajl-ruby (0.5.12)

    oortle-yajl-ruby (0.5.8)

    yajl-ruby (0.6.7)



Or even:



    $ repl git

    >> branch

      gh-pages

    * master

    >> tag

    rm

    v0.1.0

    v0.1.1

    v0.1.2

    v0.1.3

    >> tag -d rm

    Deleted tag 'rm'

    >> pwd

    git: 'pwd' is not a git-command. See 'git --help'.



    Did you mean this?

      add



You can also use `%s` to tell repl where to stick the input:



    $ repl heroku %s --app domainy

    >> info

    === domainy

    Web URL:        http://domainy.heroku.com/

    Git Repo:       [email protected]:domainy.git

    Dynos:          1

    Workers:        0

    Repo size:      288k

    Slug size:      4k

    Data size:      0K in 0 table

    Addons:         Piggyback SSL

    Owner:          b****@*******.com



If you have [rlwrap(1)][0] installed you'll automatically get the full

benefits of readline: history, reverse searches, etc.



`repl` is meant to wrap programs which accept command line arguments

and print to the standard output. It keeps no state between executed

lines and, as such, cannot be used to replace `irb` or the Python

REPL (for example).



Install

-------



### Standalone



`repl` is easily installed as a standalone script:



    export REPL_BIN=~/bin/repl

    curl -s https://raw.github.com/defunkt/repl/latest/bin/repl > $REPL_BIN

    chmod 755 $REPL_BIN



Change `$REPL_BIN` to your desired location and have at! (Just make

sure it's in your `$PATH`.)



### RubyGems



`repl` can also be installed as a RubyGem:



    $ gem install repl



Completion

----------



Because `rlwrap` supports completion, `repl` does too. Any file in

`~/.repl` matching the name of the command you start `repl` with will

be used for completion.



For instance, a file named `~/.repl/redis-cli` containing "get set

info" will cause "get", "set", and "info" to be tab completeable at

the `repl redis-cli` prompt.



The directory searched for completion files can be configured using

the `REPL_COMPLETION_DIR` environment variable.



See the [repl-completion](http://github.com/defunkt/repl-completion)

project for a few common, pre-rolled completion files.



Configuration

-------------



The following environment variables affect `repl`'s behavior:



`REPL_PROMPT`:

    the prompt to display before each line of input. defaults to >>



`REPL_COMPLETION_DIR`:

    directory in which completion files are kept



Contributing

------------



Once you've made your great commits:



1. [Fork][1] repl

2. Create a topic branch - `git checkout -b my_branch`

3. Push to your branch - `git push origin my_branch`

4. Create an [Issue][2] with a link to your branch

5. That's it!
