build.sh

build.sh provides a bash framework for building and meta-building complex software.

Supported platforms

The build.sh is tested on Mac OS X 10.15.7 and various Linux distributions(Alpine, Ubuntu)

Requirements

• bash>4.1
• Terminal with color support is recommended

Quickstart

Installation

In order to install build.sh the following steps should be done:

$ git clone https://github.com/Andrewerr/build.sh
$ chmod 755 build.sh
$ sudo ./build.sh install

Embedded usage

You can use build.sh without installation:

$ git clone https://github.com/Andrewerr/build.sh
$ chmod 755 build.sh
$ mv build.sh build
$ export "PATH=$PATH:$(pwd)"
$ # Now you can use `build` command in this session

Buildfile

The build.sh searches for file called Buildfile in your current directory. The Buildfile is basically a shell-script, but it will be loaded with build.sh and the functions in it beggining with target_ would be available for calling from shell.

Defining targets

The key concept is target. The targets is a bash function which is processed by build.sh. In order to call target you can use build <target-name>. To add target to your build file write:

target_target-name(){
  # Build steps are here
}

Hello, world!

Here is a simple example of Buildfile which prints "Hello, world".

target_hello(){
  info "Hello,world!"
}

To execute this file simply enter build hello

Using variables

USERNAME="$(whoami)"
target_hello(){
  info "Hello, $USERNAME"
}

This file will print hello to name of current user.

exec

It is important to ensure that some commands are executed correctly. The built-in command exec will abort build if the command has failed.

target_error(){
  exec "non_existent_command"
}
target_print(){   
  exec "printf '\n\nHello, world!\n\n'"
}

When you type build error you will see an error that execution of non_existent_command had failed. If you will type build print you will see Hello,world with information about what command was executed.

requires

In order to prevent build failing directly on exec you can apply require_* commands:

• require_root -- check that current user is root
• require_command <command> -- check that <command> is available in the system

Files operations

A files operationns can be done by pattern.

• copy $pattern $target -- copies files matching wilecard $pattern to $target directory.
• move $pattern $target -- moves files matching wilecard $pattern to $target directory.

Todos

• Add Dockerfile
• Implement if def, if ndef
• Incremental builds `
