# Frequently Asked Questions
## What is a CLI?
A "CLI" is a [command-line interface](https://en.wikipedia.org/wiki/Command-line_interface).
## How do I incorporate BASH3 Boilerplate into my own project?
You can incorporate BASH3 Boilerplate into your project in one of two ways:
1. Copy the desired portions of [`main.sh`](http://bash3boilerplate.sh/main.sh) into your own script.
1. Download [`main.sh`](http://bash3boilerplate.sh/main.sh) and start pressing the delete-key to remove unwanted things
Once the `main.sh` has been tailor-made for your project, you can either append your own script in the same file, or source it in the following ways:
1. Copy [`main.sh`](http://bash3boilerplate.sh/main.sh) into the same directory as your script and then edit and embed it into your script using Bash's `source` include feature, e.g.:
```bash
#!/usr/bin/env bash
source main.sh
```
1. Source [`main.sh`](http://bash3boilerplate.sh/main.sh) in your script or at the command line:
```bash
#!/usr/bin/env bash
source main.sh
```
## How do I add a command-line flag?
1. Copy the line from the `main.sh` [read block](https://github.com/kvz/bash3boilerplate/blob/v2.1.0/main.sh#L109-L115) that most resembles the desired behavior and paste the line into the same block.
1. Edit the single-character (e.g., `-d`) and, if present, the multi-character (e.g., `--debug`) versions of the flag in the copied line.
1. Omit the `[arg]` text in the copied line, if the desired flag takes no arguments.
1. Omit or edit the text after `Default=` to set or not set default values, respectively.
1. Omit the `Required.` text, if the flag is optional.
## How do I access the value of a command-line argument?
To find out the value of an argument, append the corresponding single-character flag to the text `$arg_`. For example, if the [read block]
contains the line
```bash
-t --temp [arg] Location of tempfile. Default="/tmp/bar"
```
then you can evaluate the corresponding argument and assign it to a variable as follows:
```bash
__temp_file_name="${arg_t}"
```
## What is a magic variable?
The [magic variables](https://github.com/kvz/bash3boilerplate/blob/v2.1.0/main.sh#L26-L28) in `main.sh` are special in that they have a different value, depending on your environment. You can use `${__file}` to get a reference to your current script, and `${__dir}` to get a reference to the directory it lives in. This is not to be confused with the location of the calling script that might be sourcing the `${__file}`, which is accessible via `${0}`, or the current directory of the administrator running the script, accessible via `$(pwd)`.
## How do I submit an issue report?
Please visit our [Issues](https://github.com/kvz/bash3boilerplate/issues) page.
## How can I contribute to this project?
Please fork this repository. After that, create a branch containing your suggested changes and submit a pull request based on the main branch
of <https://github.com/kvz/bash3boilerplate/>. We are always more than happy to accept your contributions!
## Why are you typing BASH in all caps?
As an acronym, Bash stands for Bourne-again shell, and is usually written with one uppercase.
This project's name, however, is "BASH3 Boilerplate". It is a reference to
"[HTML5 Boilerplate](https://html5boilerplate.com/)", which was founded to serve a similar purpose,
only for crafting webpages.
Somewhat inconsistent – but true to Unix ancestry – the abbreviation for our project is "b3bp".
## You are saying you are portable, but why won't b3bp code run in dash / busybox / posh / ksh / mksh / zsh?
When we say _portable_, we mean across Bash versions. Bash is widespread and most systems
offer at least version 3 of it. Make sure you have that available and b3bp will work for you.
We run automated tests to make sure that it will. Here is some proof for the following platforms:
- [Linux](https://travis-ci.org/kvz/bash3boilerplate/jobs/109804166#L91-L94) `GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu)`
- [OSX](https://travis-ci.org/kvz/bash3boilerplate/jobs/109804167#L2453-L2455) `GNU bash, version 3.2.51(1)-release (x86_64-apple-darwin13)`
This portability, however, does not mean that we try to be compatible with
KornShell, Zsh, posh, yash, dash, or other shells. We allow syntax that would explode if
you pasted it in anything but Bash 3 and up.
## How do I do Operating System detection?
We used to offer a magic `__os` variable, but we quickly [discovered](https://github.com/kvz/bash3boilerplate/issues/38) that it would be hard
to create a satisfactory abstraction that is not only correct, but also covers enough use-cases,
while still having a relatively small footprint in `main.sh`.
For simple OS detection, we recommend using the `${OSTYPE}` variable available in Bash as
is demoed in [this stackoverflow post](http://stackoverflow.com/a/8597411/151666):
```bash
if [[ "${OSTYPE}" = "linux-gnu" ]]; then
echo "GNU Linux"
elif [[ "${OSTYPE}" = "darwin"* ]]; then
echo "Mac OSX"
elif [[ "${OSTYPE}" = "cygwin" ]]; then
echo "POSIX compatibility layer and Linux environment emulation for Windows"
elif [[ "${OSTYPE}" = "msys" ]]; then
echo "Lightweight shell and GNU utilities compiled for Windows (part of MinGW)"
elif [[ "${OSTYPE}" = "win32" ]]; then
echo "I'm not sure this can happen."
elif [[ "${OSTYPE}" = "freebsd"* ]]; then
echo "..."
else
echo "Unknown."
fi
```
## How do I access a potentially unset (environment) variable?
The set -o nounset line in `main.sh` causes error termination when an unset environment variables is detected as unbound. There are multiple ways to avoid this.
Some code to illustrate:
```bash
# method 1
echo ${NAME1:-Damian} # echos Damian, $NAME1 is still unset
# method 2
echo ${NAME2:=Damian} # echos Damian, $NAME2 is set to Damian
# method 3
NAME3=${NAME3:-Damian}; echo ${NAME3} # echos Damian, $NAME3 is set to Damian
```
This subject is briefly touched on as well in the [Safety and Portability section under point 5](README.md#safety-and-portability). b3bp currently uses [method 1](https://github.com/kvz/bash3boilerplate/blob/v2.1.0/main.sh#L252) when we want to access a variable that could be undeclared, and [method 3](https://github.com/kvz/bash3boilerplate/blob/v2.1.0/main.sh#L31) when we also want to set a default to an undeclared variable, because we feel it is more readable than method 2. We feel `:=` is easily overlooked, and not very beginner friendly. Method 3 seems more explicit in that regard in our humble opinion.
## How can I detect or trap Ctrl-C and other signals?
You can trap [Unix signals](https://en.wikipedia.org/wiki/Unix_signal) like [Ctrl-C](https://en.wikipedia.org/wiki/Control-C) with code similar to:
```bash
# trap ctrl-c and call ctrl_c()
trap ctrl_c INT
function ctrl_c() {
echo "** Trapped CTRL-C"
}
```
See http://mywiki.wooledge.org/SignalTrap for a list of signals, examples, and an in depth discussion.
## How can I get the PID of my running script?
The PID of a running script is contained in the `${$}` variable. This is _not_ the pid of any subshells. With Bash 4 you can get the PID of your subshell with `${BASHPID}`. For a comprehensive list of Bash built in variables see, e.g., http://www.tldp.org/LDP/abs/html/internalvariables.html

# Please do not edit this file directly, but propose changed upstream instead:

#
# This Makefile offers convience shortcuts into any Node.js project that utilizes npm scripts.
# It functions as a wrapper around the actual listed in `package.json`
# So instead of typing:
#
# $ npm script build:assets
#
# you could also type:
#
# $ make build-assets
#
# Notice that colons (:) are replaced by dashes for Makefile compatibility.
#
# The benefits of this wrapper are:
#
# - You get to keep the the scripts package.json, which is more portable
# (Makefiles & Windows are harder to mix)
# - Offer a polite way into the project for developers coming from different
# languages (npm scripts is obviously very Node centric)
# - Profit from better autocomplete (make <TAB><TAB>) than npm currently offers.
# OSX users will have to install bash-completion

## Overview
<!--more-->
When hacking up Bash scripts, there are often things such as logging or command-line argument parsing that:
- You need every time
- Come with a number of pitfalls you want to avoid
- Keep you from your actual work
Here's an attempt to bundle those things in a generalized way so that
they are reusable as-is in most scripts.
We call it "BASH3 Boilerplate" or b3bp for short.
## Goals
Delete-Key-**Friendly**. Instead of introducing packages, includes, compilers, etc., we propose using [`main.sh`](https://bash3boilerplate.sh/main.sh) as a base and removing the parts you don't need.
While this may feel a bit archaic at first, it is exactly the strength of Bash scripts that we should want to embrace.
**Portable**. We are targeting Bash 3 (OSX still ships
with 3, for instance). If you are going to ask people to install
Bash 4 first, you might as well pick a more advanced language as a
dependency.
## Features
- Conventions that will make sure that all your scripts follow the same, battle-tested structure
- Safe by default (break on error, pipefail, etc.)
- Configuration by environment variables
- Simple command-line argument parsing that requires no external dependencies. Definitions are parsed from help info, ensuring there will be no duplication
- Helpful magic variables like `__file` and `__dir`
- Logging that supports colors and is compatible with [Syslog Severity levels](https://en.wikipedia.org/wiki/Syslog#Severity_levels), as well as the [twelve-factor](https://12factor.net/) guidelines
## Installation
There are three different ways to install b3bp:
### Option 1: Download the main template
Use curl or wget to download the source and save it as your script. Then you can start deleting the unwanted bits, and adding your own logic.
```bash
wget https://bash3boilerplate.sh/main.sh
vim main.sh
```
### Option 2: Clone the entire project
Besides `main.sh`, this will also get you the entire b3bp repository. This includes a few extra functions that we keep in the `./src` directory.
```bash
git clone git@github.com:kvz/bash3boilerplate.git
```
### Option 3: Require via npm
As of `v1.0.3`, b3bp can also be installed as a Node module, meaning you can define it as a dependency in `package.json` via:
```bash
npm init
npm install --save --save-exact bash3boilerplate
```
Even though this option introduces a Node.js dependency, it does allow for easy version pinning and distribution in environments that already have this prerequisite. This is, however, entirely optional and nothing prevents you from ignoring this possibility.
## Changelog
Please see the [CHANGELOG.md](./CHANGELOG.md) file.
## Frequently Asked Questions
Please see the [FAQ.md](./FAQ.md) file.
## Best practices
As of `v1.0.3`, b3bp offers some nice re-usable libraries in `./src`. In order to make the snippets in `./src` more useful, we recommend the following guidelines.
### Function packaging
It is nice to have a Bash package that can not only be used in the terminal, but also invoked as a command line function. In order to achieve this, the exporting of your functionality _should_ follow this pattern:
```bash
if [[ "${BASH_SOURCE[0]}" = "${0}" ]]; then
my_script "${@}"
exit $?
fi
export -f my_script
```
This allows a user to `source` your script or invoke it as a script.
```bash
# Running as a script
$ ./my_script.sh some args --blah
# Sourcing the script
$ source my_script.sh
$ my_script some more args --blah
```
(taken from the [bpkg](https://raw.githubusercontent.com/bpkg/bpkg/HEAD/README.md) project)
### Scoping
1. In functions, use `local` before every variable declaration.
1. Use `UPPERCASE_VARS` to indicate environment variables that can be controlled outside your script.
1. Use `__double_underscore_prefixed_vars` to indicate global variables that are solely controlled inside your script, with the exception of arguments that are already prefixed with `arg_`, as well as functions, over which b3bp poses no restrictions.
### Coding style
1. Use two spaces for tabs, do not use tab characters.
1. Do not introduce whitespace at the end of lines or on blank lines as they obfuscate version control diffs.
1. Use long options (`logger --priority` vs `logger -p`). If you are on the CLI, abbreviations make sense for efficiency. Nevertheless, when you are writing reusable scripts, a few extra keystrokes will pay off in readability and avoid ventures into man pages in the future, either by you or your collaborators. Similarly, we prefer `set -o nounset` over `set -u`.
1. Use a single equal sign when checking `if [[ "${NAME}" = "Kevin" ]]`; double or triple signs are not needed.
1. Use the new bash builtin test operator (`[[ ... ]]`) rather than the old single square bracket test operator or explicit call to `test`.
### Safety and Portability
1. Use `{}` to enclose your variables. Otherwise, Bash will try to access the `$ENVIRONMENT_app` variable in `/srv/$ENVIRONMENT_app`, whereas you probably intended `/srv/${ENVIRONMENT}_app`. Since it is easy to miss cases like this, we recommend that you make enclosing a habit.
1. Use `set`, rather than relying on a shebang like `#!/usr/bin/env bash -e`, since that is neutralized when someone runs your script as `bash yourscript.sh`.
1. Use `#!/usr/bin/env bash`, as it is more portable than `#!/bin/bash`.
1. Use `${BASH_SOURCE[0]}` if you refer to current file, even if it is sourced by a parent script. In other cases, use `${0}`.
1. Use `:-` if you want to test variables that could be undeclared. For instance, with `if [[ "${NAME:-}" = "Kevin" ]]`, `$NAME` will evaluate to `Kevin` if the variable is empty. The variable itself will remain unchanged. The syntax to assign a default value is `${NAME:=Kevin}`.
