rake assets:precompile not processing .hamlc

[ar7hur]

When I run "bundle exec rake RAILS_ENV=production assets:precompile", hamlc templates are not compiled. They are just put as is in the /assets directory.

On-the-fly compilation (like in development mode) works perfectly though.

Did I miss something ?

Can you try setting

config.assets.initialize_on_precompile = true

in your config/environments/production.rb?

[ar7hur]

You are the best !

I thought I did it, but I did not. It works perfectly. Congrats for the great job, this gem is changing my life :)

Glad to hear you like it! The hint came from @thibaudgg and I thought it only applies to Heroku. I'll update the README.

It always happens when you compile your assets in production mode.

This is an awesome gem, thanks. I did have one question specifically about this before I dig into it too much. I was wondering why it needed the full environment to precompile the assets (specifically the initialize_on_precompile flag in production). To make a long story short with my project on Heroku this is making me have to precompile assets before deploy, which I'd rather not do. If it's not too bad I'd be willing to dig in and try to relax this dependency, but I thought I'd ask about it first, because there might be a very legitimate reason that the dependency on the environment exists (or maybe it's just too difficult to pull it out). Thanks!

I haven't played with the initialize_on_precompile flag yet and the docs aren't very clear on this. What does partially in "you can partially load your application" mean? I don't know which parts are loaded or not.

[axs89]

Yeah, it's definitely a little confusing, and the docs don't help much. The main side effect of that flag (for me) is that it loads the entire rails environment, and initializers and other code that looks for a database connection will be allowed to run. That presents a bit of an issue when you're deploying to Heroku and want to compile resources at slug compilation (they have a writeup on the issue).

In any case other types of assets don't require the full environment and I suspect that we could probably get these hamlc templates compiled without it, so I'll dig around a bit and see if I can come up with something.

[netzpirat]

The only dependencies are the execjs gem for compiling and rails for registering the engine. I remember I saw another asset pipeline gem that had a dependency to the railtie gem and not rails. Perhaps worth giving it a try.

[axs89]

I think I got it (just sent a pull request). Turns out it was a relatively straightforward option to the Railtie initialization.
