Hi,
I'm trying to do asset versioning with make, but the solution I came up with
isn't perfect.
I want to minify `src/foo.js` and then copy the minified content to
`dist/foo.[hash].js`, where `[hash]` is the sha1 hash of minified content.
Right now I do it like this:
```make
.DEFAULT_GOAL = all
src=src/foo.js
stage/%: src/% | stage
jsmin $< >$@
%.dist.d: % | stage
makehashdep $(patsubst stage/%,dist/%,$<) $< dist
-include $(src:src/%=stage/%.dist.d)
.PHONY: all
all: $(dist)
$(dist): | dist
cp $< $@
.PHONY: clean
clean:
rm -r stage dist
stage dist:
mkdir $@
```
where `makehashdep` is
```bash
target=$1
src=$2
var=$3
hashed=${target%.*}.$(sha1sum $src).${target##*.}
echo $hashed: $src
echo $var += $hashed
```
With this config, executing `make` does what I want. But there are two issues:
1. `make clean` will try to build the files in `stage` first and then remove
the directories.
2. I need to maintain a make variable in `makehashdep`, which feels out of
place.
Any idea how I can do asset versioning without these issues?
Thank you.
