central-script

Sometimes people use a Makefile (Make) just to have a list of shortcuts for frequently used commands. For example:

Makefile
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
.PHONY: prepare lint build-docker

prepare:
    sudo apt-get update
    sudo apt-get install -y docker.io

lint:
    npx prettier -c .

build-docker: lint
    docker build -t $(imgname) .

I know that Make can do a lot more than that, but sometimes, for simple scenarios, this is enough. If this is the case, in my opinion there's no reason to use Make at all: we can do pretty much the same with a simple Bash script like the following:

Bash
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
#!/bin/bash

set -e

cd "$(dirname "$0")"

target_prepare() { sudo apt-get update; sudo apt-get install -y docker.io; }
target_lint() { npx prettier -c .; }
target_build_docker() { target_lint; docker build -t "$1" .; }

while IFS= read -r i || [ -n "$i" ]; do "target_$i" "${@:2}"
    done < <(printf '%s\n' "$1" | tr , '\n')

Then we can save it in the root of our project and invoke it like this:

Bash
1
bash central.sh prepare,build-docker myimage
