How to compile (watch) all files in a directory and recursively?

[philip andrew]

Hi there,

How can I compile and watch all files in a directory recursively?

Thanks, Philip

No built in way of doing it unfortunately, you can of course do 'pogo -cw *.pogo' for all files in a directory and some shells (zsh, and newish bash) allow a recursive glob allowing 'pogo -cw **/*.pogo'. Neither will find new files as you create them though.

For node.js projects I don't find this a problem since you can just run the pogo directly, and when you really want the JS I write a Makefile (old school!)

For web, you can use something like connect-compiler to compile the JS and cache when things change, I have a patched one at github.com/featurist/connect-compiler. Or use something like stitchy (on npm), which will put it all into one app.js file, usually better for web projects anyway.

I do have intentions of including some of features in pogo itself, especially recursive watch, but lets do source maps first! :)

Yes I use Yeoman for web builds, http://yeoman.io/.

I'll take a look at these two, not sure how to use them yet in my Grunt build file.

Thanks

Hi Tim,

I guess what I need is the equivilent of Grunt Contrib Coffee.

https://github.com/gruntjs/grunt-contrib-coffee

In my Gruntfile.js it has:

  grunt.initConfig({

    yeoman: yeomanConfig,

    watch: {

      coffee: {

        files: ['<%= yeoman.app %>/scripts/{,*/}*.coffee'],

        tasks: ['coffee:dist']

      },

Which uses the coffee task to compile the scripts...

Looks like a good idea, not familiar with those tools but sounds like I should be!

There is an API for pogo, including methods for compilation and evaluation. They're not documented, but are stable and could help you with anything you might want to do with grunt.

    pogo = require 'pogo'

    pogo.compile (...)

    pogo.evaluate (...)

See https://github.com/featurist/pogoscript/blob/master/lib/parser/compiler.pogo.

Hi,

Yes thanks for the API - I wrote my own code based upon yours slightly, written in Coffeescript, assuming your a developer and you start with Coffeescript.

Thats immediately obvious to you of course, but for any other developer who comes along, they may want to compile all *.pogo files in a directory and have the *.js outputted to another directory and do it from node js javaascript.

It could be improved to support scanning for changes in the files by comparing the timestamp of changed file, also to run in a loop polling could be an improvement.

I'm doing a project using some of Pogoscript for the Intel Perception Computing Challenge, https://perceptualchallenge.intel.com/ - cross my fingers and hope to win.

Use Kjscompiler - makes compilation of multiple JavaScript files with Google Closure Compiler application in right order.
