|

GNU make is an excellent build tool and the task runner we love to hate, but can't escape.
|
||||
So let's improve the UX to make it the best task runner it can be.
|
||||
|
||||
So I give you `task.mk`, a standalone makefile you can deploy alongside your own
|
||||
`Makefile`'s to add some QOL improvements for your users and fellow maintainers.
|
||||
`Task.mk`, is a standalone `Makefile` you can deploy alongside your own
|
||||
to add some QOL improvements for your users and fellow maintainers.
|
||||
|
||||
Current Features:
|
||||
- ANSI Color Support
|
||||
- Formatted Help Screen
|
||||
- Custom print function
|
||||
- ANSI escape code support (including NO_COLOR)
|
||||
- formatted help output
|
||||
- custom print function
|
||||
|
||||
Depends on `GNU Make`, obviously and `Python >=3.7`.
|
||||
|
||||
Wait python?!, I'm not `pip` installing some package just to parse my makefile.

||||
Wait python?!?!, I'm not `pip` installing some package just to parse my makefile.
|
||||
I agree, so I've hacked together a file containing the bits of python we need with some tricks to run it.
|
||||
|
||||
## Usage
|
||||
## Setup
|
||||
|
||||
You can include this as an optional dependency on your project by adding the below lines the end of your make file.
|
||||
When your users first your `make help` it will download `task.mk`.
|
||||
If you intend to use any of the other features like `tprint` (see below),
|
||||
I'd recommend committing `.task.mk` into version control so behavior is consistent.
|
||||
You can include this as an optional dependency on your project by adding the below lines to the end of your `Makefile`.
|
||||
If someone tries to invoke `make help` it will download `.task.mk` for them.
|
||||
|
||||
```make
|
||||
-include .task.mk
|
||||
$(if $(filter help,$(MAKECMDGOALS)),.task.mk: ; curl -fsSL https://raw.githubusercontent.com/daylinmorgan/task.mk/22.9.5/task.mk -o .task.mk)
|
||||
```
|
||||
|
||||
If you intend to use any of the other features like `tprint` (see below),
|
||||
I'd recommend committing `.task.mk` into version control so behavior is consistent.
|
||||
|
||||
```bash
|
||||
curl -fsSL https://raw.githubusercontent.com/daylinmorgan/task.mk/22.9.5/task.mk -o .task.mk
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
`Task.mk` will add access to a recipe `help` (also aliased to `h`).
|
||||
In order to use `make help` to you will need to add some custom comments to your `Makefile`.
|
||||
|
||||
Deliberately, I don't get names from recipes themselves.
|
||||
This not only greatly simplifies the parsing but add's some opportunity to customize the output.
|
||||
Such as to document wildcard or redundant recipes.
|
||||
|
||||
You can place these anywhere, but I recommend adding these notes directly above their relevant recipes.
|
||||
The format is `## <recipe> | <msg>`
|
||||
|
||||
```make
|
||||
## build | build the project
|
||||
.PHONY: build
|
||||
build:
|
||||
...
|
||||
```
|
||||
|
||||
Now when you invoke `task.mk` it will parse these and generate your help output.
|
||||
|
||||
In addition to a generic help output you can expose some configuration settings with `make vars`.
|
||||
To do so define the variables you'd like to print with `PRINT_VARS := VAR1 VAR2 VAR3`.
|
||||
|
||||
In addition to the `help` and `vars` recipes you can use a custom make function to format your text for fancier output.
|
||||
For this there are two options depending on your needs `tprint` or `tprint-sh`. (`tprint-sh` is for use within a multiline sub-shell that has already been silenced, see the version-check rule of this project's `Makefile` for an example.)
|
||||
|
||||
|
||||
To use `tprint` you call it with the builtin `make` call function.
|
||||
It accepts only one argument: an unquoted f-string literal.
|
||||
All strings passed to `tprint` have access to an object `ansi` or `a` for simplicity.
|
||||
This stores ANSI escape codes which can be used to style your text.
|
||||
|
||||
```make
|
||||
## build | compile the source
|
||||
.PHONY: build
|
||||
build:
|
||||
$(call tprint,{a.cyan}Build Starting{a.end})
|
||||
...
|
||||
$(call tprint,{a.green}Build Finished{a.end})
|
||||
```
|
||||
See this projects `make info` for more examples of `tprint`.
|
||||
|
||||
To see the available colors and formatting(bold,italic,etc.) use the hidden recipe `make _print-ansi`.
|
||||
|
||||
**Note**: Any help commands starting with an underscore will be ignored.
|
||||
To view hidden `tasks` (or recipes in GNU Make land) you can use `make _help`.
|
||||
|
||||
## Configuration
|
||||
|
||||
You can quickly customize some of the default behavior of `task.mk` by overriding the below variables prior to the `-include .task.mk`.
|
||||
|
||||
```make
|
||||
# ---- CONFIG ---- #
|
||||
HEADER_COLOR ?= b_cyan
|
||||
PARAMS_COLOR ?= b_magenta
|
||||
ACCENT_COLOR ?= b_yellow
|
||||
GOAL_COLOR ?= $(ACCENT_COLOR)
|
||||
MSG_COLOR ?= faint
|
||||
HELP_SEP ?= |
|
||||
HELP_SORT ?= # sort goals alphabetically
|
||||
|
||||
# python f-string literals
|
||||
EPILOG ?=
|
||||
define USAGE ?=
|
||||
{ansi.$(HEADER_COLOR)}usage{ansi.end}:
|
||||
make <recipe>
|
||||
|
||||
endef
|
||||
```
|
||||
|
||||
**NOTE**: `HELP_SEP` does not change the argument definitions syntax only the format of `make help`.
|
||||
|
||||
## Advanced Usage: Embedded Python Scripts
|
||||
|
||||
You can take advantage of the builtin python script runner and write multi-line python scripts of your own.
|
||||
This is a simple example but a few lines of python in your `Makefile`
|
||||
may be easier than balancing sub-shells and strung together awk commands.
|
||||
|
||||
When `make` expands the function it will take the parameters passed to `py` and expand them `$(1)` is the variable name.
|
||||
`$(2)` in this case is the implicit pattern from the rule. Pay attention to quotes.
|
||||
If you need to debug your python script, use `DEBUG=1` when you run `make` and it will first print the script that will be piped to `python`.
|
||||
|
||||
```make
|
||||
define list_files_py
|
||||
from pathlib import Path
|
||||
print("files in $(2)")
|
||||
print([f.name for f in (Path("$(2)").iterdir())])
|
||||
endef
|
||||
|
||||
## list-% | use pathlib.Path to list files
|
||||
list-%:
|
||||
$(call py,list_files_py,$*)
|
||||
```
|
||||
|
||||
For what it's worth there is also a predefined function for `bash` (named `tbash`) as well should you need to accomplish something similar of more easily embedding your bash script rather than having to escape every line with '\'.
|
||||
|
||||
```make
|
||||
define bash_script
|
||||
echo "This is from bash"
|
||||
cat /etc/hostname
|
||||
printf "%s\n" "$(2)"
|
||||
endef
|
||||
.PHONY: test-bash
|
||||
test-bash:
|
||||
$(call tbash,bash_script,test bash multiline)
|
||||
```
|
||||
|
||||
|
||||
|
||||
## Zsh Completions for GNU Make
|
||||
|
||||
If you use `GNU Make` with zsh you may want to add the following
|
||||
line to your rc file to allow `make` to handle the autocomplete.
|
||||
|
||||
```zsh
|
||||
zstyle ':completion::complete:make:*:targets' call-command true
|
||||
```
|
||||
|
||||
## Why Make?
|
||||
|
||||
There are lot of `GNU Make` alternatives but none have near the same level of ubiquity.
|
||||
This project attaches to `make` some of native features of [`just`](https://github.com/casey/just), a command runner.
|
||||
|
||||
Just is a great task runner, but it suffers two problems, users probably don't have it installed already, and there is no way to define file specific recipes.
|
||||
Most of my `Makefile`'s are comprised primarily of handy `.PHONY` recipes, but I always end up with a few file specific recipes.
|
||||
|
||||
Another interesting project I've evaluated for these purposes is [`go-task/task`](https://github.com/go-task/task).
|
||||
`Task` has many of the features of `GNU Make` and some novel features of it's own.
|
||||
But like `just` it's a tool people don't usually already have and it's configured using a `yaml` file.
|
||||
`Yaml` files can be finicky to work with and and it uses a golang based shell runtime not your native shell, which might lead to unexpected behavior.
|
||||
|
||||
|
||||
## Simpler Alternative
|
||||
|
||||
But I just want a basic help output, surely I don't need python for this... you would be right.
|
||||
`Task.mk` replaces my old `make help` recipe boilerplate which may better serve you.
|
||||
|
||||
|
||||
```make
|
||||
## h, help | show this help
|
||||
.PHONY: help h
|
||||
help h: Makefile params
|
||||
@awk -v fill=$(shell sed -n 's/^## \(.*\) | .*/\1/p' $< | wc -L)\
|
||||
'match($$0,/^## (.*) \|/,name) && match($$0,/\| (.*)$$/,help)\
|
||||
{printf "\033[1;93m%*s\033[0m | \033[30m%s\033[0m\n",\
|
||||
fill,name[1],help[1];} match($$0,/^### (.*)/,str) \
|
||||
{printf "%*s \033[30m%s\033[0m\n",fill," ",str[1];}' $<
|
||||
```
