Makefile

##
# This Makefile is a slimmed down version from an actual project, to make deployment
# easier all the html files in `views/` are copied into Go files as constants and
# placed under `src/views/`, assuming `GOPATH="$PWD/.deps:$PWD" (1) this means that in
# your code you can get the contents of `views/index.html` as `views.INDEX`.
# 
# There is also how I handle dependencies with gpm, which is unrelated, but I though
# I'd leave it for the hell of it.
# 
# (1) You don't need to have that exact GOPATH, but "$PWD" does need to be included in
# it so you can import "views" from `src/views` and use it.

VIEWS = $(patsubst views/%.html,src/views/%.go,$(wildcard views/*.html))

.deps/.installed: Godeps
	gpm install && touch $@

build: *.go .deps/.installed $(VIEWS)
	go build -o <your_binary_name>

# Views -> Go files

src/views:
	mkdir -p $@

src/views/%.go: views/%.html
	#echo 'package views\n\nconst $(shell echo $* | tr a-z A-Z) = `$(shell cat views/$*.html)`' > $@
	./asset_to_go "$*"

Tené en echo a secas no interpreta los \n:

inkel@miralejos ~/tmp
$ echo "package views\n\nconst $(git ls-files lib)"
package views\n\nconst lib/disyuntor.rb
lib/disyuntor/version.rb
lib/rack/disyuntor.rb

Para eso necesitás usar -e, así:

inkel@miralejos ~/tmp
$ echo -e "package views\n\nconst $(git ls-files lib)"
package views

const lib/disyuntor.rb
lib/disyuntor/version.rb
lib/rack/disyuntor.rb
