Make this a command line tool

[ye]

Hi Joel,

Nice work! In order to make this piece of code more widely usable, can you make this compiled into a command line tool?

Much appreciate it!

@ye Yes. I think that would be a natural direction to go in. My guess is it would be beneficial to both compile frak to a jar and a JavaScript file; the latter being preferable.

:+1: Nice work @noprompt, the benchmarks you've posted are really impressive. A JS library would be extremely appreciated.

[noprompt]

@philipkobernik Thanks. A command line version and a standalone JS lib will be available soon (for those who don't use ClojureScript).

If you have leiningen and nodejs installed and want to try out the command line version, clone this repo and checkout the cli branch. Then compile the code to JavaScript:

$ lein cljsbuild once prod

Then try:

$ mv bin/frak.prod.js bin/frak
$ chmod +x bin/frak
$ bin/frak --help
Usage: frak <flags*> <strings+>

    -e, --exact     Generated pattern requires an exact match
    -c, --capture   Generated pattern captures
    -h, --help      Display this help message

$ bin/frak --exact bat ban barn bar box born bird

@noprompt I've followed the steps above and tried to run it but had this error:

@ye Apparently ClojureScript doesn't like the char? function. I've changed the code to use a different strategy and retried everything. It should work properly now.

[noprompt]

I've merged the cli branch with master and plan to release instructions when I push the new version of frak this week. The new instructions until then are:

$ lein do cljx once, cljsbuild once node
$ chmod +x bin/frak

Edit: Correction to lein command

[yPhil-gh]

@noprompt Dit you push it yet ?

$ git clone https://github.com/noprompt/frak.git

Copying 25 files to /home/px/tmp/frak/.lein-plugins That's not a task. Use "lein help" to list all tasks.

I tried checking out the cli branch, but Leininger keeps complaining about the command syntax..?

[noprompt]

@xaccrocheur Oh, whoops! I made a mistake. It should be lein do cljx once, cljsbuild once node.

[noprompt]

Instructions are now available in the README.
