Generate image URLs with a different base

[rhunter]

Currently Sprite assumes that all its work happens under a "public" directory, and that "public" directory is published at "/".

That's not the case for me -- I'm working in a Java environment with a layout like the following:

static-ui/
src/
main/webapp/
images/
style/
target/
webapp/ # published as /static-ui/
images/ # published as /static-ui/images/
style/

I'd like to generate URLs like "/static-ui/images/mysprite.png", or even "http://images.example.com/mysprite.png"

(I'm fixing this in my own fork, but leaving this ticket as a record and for discussion)

I have a fix for this in amikula/sprite...you can install it with "gem install amikula-sprite". The config is css_image_path. Which fork is yours? I've looked at all the github forks and I didn't notice a patch for this anywhere.

The issue dropped in our project (the UI devs decided they were happy to do spriting by hand) and I never got around to committing my changes.

I've just dug up the code and pushed what I had -- it adds a config property "external_base" to describe the "target" folder.
