Would it be feasible to extend shake to being a configuration tool too?
In the vein of Puppet/Chef; I would really like to use Shake for more than just local builds. I think the principles of Shake are abstract enough (I haven't dug deep though to know) that it could be used as the foundation for a larger configuration…

Adding system' actions should change the rule history
I have this kind of rule:
"foo" *> \out do
need something
create "foo" somehow
It's built correctly, and running the build twice won't build the target.
Then I add a system' to this rule:
"foo" *> \out do
...
system' something

How to debug shake rules execution?
I love Shake as a build system, but one thing I find hard with Shake is to troubleshoot rules triggering issues. I often run into a situation where I think something should not be rebuilt yet it is rebuilt.
What are some guidelines to troubleshoot…

How do I skip a shake Action?
I'd like to download a bunch of web pages with shake, then do some processing on them. However, I'd also like the option to download the pages outside of shake, tell shake I've done so, and let shake continue with the remainder of the processing…

Haskell shake: special rule for building directories
Sometimes it is the case that to create a directory mkdir is not the right tool. It may be git clone or rsync or mount. So when we have a rule like this:
needDir dirs = filterM ((fmap not) . doesDirectoryExist) dirs >>= need

Why Shake dependencies are explicitly `needed`?
I find first example of Shake usage demonstrating a pattern that seems error prone:
contents <- readFileLines $ out -<.> "txt"
need contents

I use shake to build a bunch of static webpages, which I then have to upload to a remote host, using sftp. Currently, the cronjob runs
git pull # get possibly updated sources

I’d like to avoid running the final…

Shake for cross-compilations?
I've got a project that builds two sets of targets. One is firmware for various version of a handheld device that ultimately creates a .dfu file for each device. This uses the arm compilation chain. The other set are emulators for those same devices…

How to define a timer rule in Shake
I'm trying to understand how to use Shake and how to build new rules. As an exercise, I've decided to implement what I call a backup rule.
The idea is to generate a file if it doesn't exists OR if it's too old (let's more than 24 hour). I like to…

How can Shake FilePatterns be used to minify JS and CSS files?
Common practice with .js and .css file minification is to create .min.js and .min.css files. The problem is Shake FilePatterns will match both minified and non-minified files with this scheme with a pattern like //*.js. The docs seem to recommend…
