[RFC] fftools/resorces: Add resource_manager with build-time compression
Hello everybody,
this is a resource manager implementation which I've done for the
upcoming execution graph rendering patchset, which needs some css and
http strings for generating the output and I wanted check back whether
it's okay to do it that way?
To minimize the amount of storage required, it is using compression at
build time, inspired from the PTX compresion that is already in employed
for compresing CUDA kernels. The purpose is to allow having the actual
content in the tree, viewable and editable as reeguar html or css files
rather than a cryptic string that is handcrafted by the developer.
For CSS files, it also applies some minification: Comment lines are
removed, linebreaks removed and whitespace is folded, then it gets
compressed and finally added as data via BIN2C. Same for html but
without minification.
In case of PTX compression there's a configure option to disable, hence
I'm wondering whether I might need to do the same if there are any cases
where it doesn't work?
Thanks
(note that the two css and html files are identical - it's just for
illustration).
