Modules Manager: JPM


#1

I've written, for my own benefit, a JUCE modules manager.  But I think I'd like to share it if people are interested in contributing.

It's a bit like npm, but for JUCE modules. 

What does it do I hear you say... :)

Well, for example, you type: 

jpm install juce_core@3.1.1

And it downloads and installs juce_core, and configures your .jucer file for you. 

Or even:

jpm install juce_*@4.0.1

To download and setup everything starting with juce_

It also saves a local file containing a specification for the modules and versions you used with the project so if you share it without the modules someone else can run jpm install and it'll go and download all the same stuff, at the same version.   It caches the modules locally so it's quick too.

It stores all the modules in a folder called jpm_modules in your JUCE project.

Why do you want this?

  • It's quick, easy and extendable.
  • It saves faffing around with the 'set modules paths' stuff which is painful when you have non-JUCE modules to include as well.
  • It makes it easier to reuse code
  • It means you get the right version of the module without having to faff around with git submodules, or bundling the modules with the rest of your code.
  • It makes it easy to find more modules...certainly if other people contribute.  You can type jpm list and it shows you what's available.  

It'll support, shortly, mutiple directories so you can have a local module archive too of your private stuff.   

I'm also planning on having it create and update modules more easily from a bunch of source files.  But that's next ... 

So if you have modules and you'd be interested in adding them to my list, or you fancy having a play with the alpha version, fixing bugs etc let me know :)  I'll post some code in a tic...

PS. it doesn't tackle dependencies at the moment, but that's not a big problem for me right now.

So you get the vibe, heres an example of it running on my Windows box - the directory isn't fully populated:

Thanks for this, this is something I've been wanting for ages and had thought about trying myself, time allowing. I'd definitely be up for contributing. Have you thought about where to store all the module info? REST access to a database somewhere? I'd be up for helping with that side of things.. 


#3

Wow, very cool.

Just as a heads-up, something I want to do very soon is to simplify the design of modules, probably eliminating the manifest file and changing the way include paths work. Will post more detail when I can!

There's the link.  There's a mac binary there as well.  

Anyone know of other modules we should put on the list?  I'm going to pop the font awesome stuff into a module shortly ... :)


#5

There's something pretty fundamentally wrong about the include pathes for dependencies on other modules at the moment.  If you have a module in some random folder X then how does it know where the JUCE modules will be so it can do something like: 

#include "../juce_core/juce_core.h"

#include "../juce_graphics/juce_graphics.h"

Ah - ignore me... I can do angle brackets and the include paths are all sorted ;-)  


#6

Yeah, one of the things I want to change is to remove all those annoying introjucer-generated indirection headers within your own project folder, and just use angle-bracket includes everywhere.


#7

RIght now with danlin's FontAwesome module, and I've put the lock-free utility classes I have together into a module too: 

I've also fixed it up so you can generate JUCE Modules with the genmodule command and it sorts out the various headers, and juce_module_info file along with a simple Doxygen config.  So to create a module the minimum you need to do is to put your source files in a folder, run jpm and you're done :)   Very pleased with that.  

What I should do now is some proper work ... but what I actually want to do is sort out a new module just so I can use it :)
