Makefile snippets (aka "makelets" :smile:) that I use for building golang projects. Everyone likes their own, I like these :bowtie: Just wanted a public place to put them so I don't end up with scattered copies everywhere .. so this repo is kind of intended just for my benefit, but maybe you'll find a use too. If you'd like something else included, then fork away and send a PR if you like.
There are a few different example projects which demonstrate usage. I didn't include them in here for two reasons: (1) so that you can easily see what's needed in your own projects, (2) to keep this repo slightly simpler. The examples:
Along with the makelets, this repo also contains a simple CLI tool to generate various scaffolding. Further info on the CLI tool is available there.
It's definitely recommended that you use autocomplete for make.
These targets are supported by batteries.mk:
| Target(s) | Description |
|---|---|
install | Does a go install |
vendor | Uses glide to install versioned packages to your vendor directory |
lint-fast, lint, lint-full | Uses gometalinter to scan for possible nasties. The different targets just enable different options, either --fast,default, or --enable-all |
test-short, test | invokes go test on all local packages (it skips the vendored ones).test-short will pass the --short option in case you have some teststhat take a long time to run (e.g. testing timeouts etc) |
coverage-short, coverage | uses gocov to invoke go test on all your local packages, generating code coverage info. Also builds an HTML file that shows which source lines are not covered by your tests |
clean:: | it's a double-colon make rule so that it can be extended by your own makefile |
clobber:: | gets things really really clean, it will invoke the clean target first |
and these are defined elsewhere, included above:
| Target(s) | Description |
|---|---|
gopath | Allows you to run eval $(make gopath) from your bash shell, sets up $GOPATH in your environment and adds $GOPATH/bin to your $PATH |
| Variable | Description |
|---|---|
$(call PROMPT, ...) | Use in a make rule, just prints a little banner heading with some text |
STRIP_DEBUG | Define options to pass to go build via -ldflags to strip debug for smaller binaries |
Most of the tool support is quite simple, in many cases not much more than something to install the tool and a make variable to refer to the binary. Others are more fully featured. Brief info follows below.
There are a plethora of package managers / vendoring tools for go at the moment. I currently use glide.
Defined variables:
| Variable | Description |
|---|---|
$(GLIDE) | Refers to the glide executable. You can depend on this to get glide installed |
$(GLIDE_OPT_INSTALL) | options to be passed to glide install (used to install package dependencies) |
Superb wrapper to simplify running a whole bunch of linters on your code. See gometalinter
This makelet defines a few settings which you can override before you include gomake.
Defined variables:
| Variable | Description |
|---|---|
$(GOMETALINTER) | Refers to the gometalinter executable. You can depend on this to get gometalinter installed |
$(GOMETALINTER_OPT) | Sets up some default options for gometalinter (including the settings just below) |
$(GOMETALINTER_LINELENGTH) | Sets the text line length used during linting |
$(GOMETALINTER_DEADLINE) | Sets the a linting time deadline (some linters can take quite a while...) |
$(GOMETALINTER_CYCLO) | Sets the cyclomatic complexity used during linting |
The goconvey makelet needs no other integration in your main makefile. Just run as follows (from your repo):
$ make goconvey
And it should install itself and fire up a webpage on http://127.0.0.1:8080.
All your go test tests will be run on any code change, and you can
get browser notifications when a test fails.
gocov provides a nice wrapper around go test
by simplifying the process of getting code coverage on a per-package basis.
The gocov-html generates a nice HTML file
where you can easily see which source lines are not tested.
Useful to embed directories of static files into binaries. See go.rice
| Variable | Description |
|---|---|
$(RICE) | Refers to the rice executable. You can depend on this to get it installed |
Sometimes, or for gopherjs, you may want to include assets as part of the compilation
process instead of using rice (above). In those cases, go-bindata
can be very useful.
| Variable | Description |
|---|---|
$(GO_BINDATA) | Refers to the go-bindata executable. You can depend on this to get it installed |
| Variable | Description |
|---|---|
$(GOAGEN) | Refers to the goagen executable. You can depend on this to get it installed |
There are make targets defined for each goa generate command, see table below. This can be useful as part of a make process to ensure things are always up-to-date.
| Target(s) | Description |
|---|---|
| goagen-app | Runs the goagen "app" command |
| goagen-bootstrap | Runs the goagen "bootstrap" command |
| goagen-client | Runs the goagen "client" command |
| goagen-controller | Runs the goagen "controller" command |
| goagen-gen | Runs the goagen "gen" command |
| goagen-js | Runs the goagen "js" command |
| goagen-main | Runs the goagen "main" command |
| goagen-schema | Runs the goagen "schema" command |
| goagen-swagger | Runs the goagen "swagger" command |
golang in the browser #FTW. See gopherjs
| Variable | Description |
|---|---|
$(GOPHERJS) | Refers to the gopherjs executable. You can depend on this to get gopherjs installed |
$(TEMPLE) | Refers to the temple executable (used to enable go-templates for client-side markup generation). You can depend on this to get temple installed |
Allows you to print the git tag/hash of the repo when your app runs. See github.com/gravitational/version or the godocs for more info.
Use this define something like:
$(BIN): | $(CMD_LINKFLAGS)
$(GO) build -ldflags='$(call VERSION_LDFLAGS_VENDOR,github.com/example/myrepo)'
NB, this assumes you've vendored this package. If not, then omit the _VENDOR in the line above.
Part of a separate repo, so that you can use the docker makelets in non-go projects. See github.com/go-make/docker
