- `master` is automatically tested on Travis
- Docker builds a new `latest` image
## Coding Style
### Bash and Shell
When refactoring, writing or altering Script, that is Shell and Bash scripts, in any way, adhere to these rules:
1. **Adjust your style of coding to the style that is already present**! Even if you do not like it, this is due to consistency. Look up the GNU coding style guide. There was a lot of work involved in making these scripts consistent.
2. **Use `shellcheck` to check your scripts**! Your contributions are checked by TravisCI with shellcheck.
3. There is a **`.editorconfig`** file. Make your IDE use it or adhere to it manually!
4. It's okay to use `/bin/bash` instead of `/bin/sh`. You can alternatively use `/usr/bin/env bash`.
5. `setup.sh` provides a good starting point to look for.
6. When appropriate, use the `set` builtin. We recommend `set -euEo pipefail` (very strong) or `set -uE` (weaker).
#### Styling rules
##### initial description
When writing a script, provide the version and the script's task like so:
``` BASH
#!/usr/bin/env bash
# version 0.1.0
#
# <TASK DESCRIPTION> -> cut this off
# to make it not longer than approx.
# 60 cols.
```
We use [semantic versioning](https://semver.org/) - so do you.
##### if-else-statements
``` BASH
if <CONDITION1>
then
<CODE TO RUN>
elif <CONDITION2>
<CODE TO TUN>
else
<CODE TO RUN>
fi
# when using braces, use double braces!
if [[ <CONDITION1> ]] && [[ <CONDITION2> ]]
then
<CODE TO RUN>
fi
# remember you do not need "" when using [[ ]]
if [[ -f $FILE ]] # is fine
then
<CODE TO RUN>
fi
# equality checks with numbers - use -eq/-ne/-lt/-ge, not != or ==
if [[ $VAR -ne <NUMBER> ]] && [[ $SOME_VAR -eq 6 ]] || [[ $SOME_VAR -lt 42 ]]
then
<CODE TO RUN>
elif [[ $SOME_VAR -ge 242 ]]
then
<CODE TO RUN>
fi
```
##### variables
Variables are always uppercase.
``` BASH
# good
local VAR="good"
# bad
var="bad"
```
##### braces
We use braces in the following way:
``` BASH
# when it's clear and unambiguous,
# you do not have to use braces,
# but you might, see shellcheck SC2248
$VAR
# or
${VAR}
# when the variable is used
# in a bigger context
echo "/some/dir/${VAR}/to/destination/"
```
##### loops
Like `if-else`, loops look like this
``` BASH
for / while <LOOP CONDITION>
do
<CODE TO RUN>
done
```
##### functions
It's always nice to see the use of functions. Not only as it's more C-style, but it also provides a clear structure. If scripts are small, this is unnecessary, but if they become larger, please consider using functions. When doing so, provide `function _main()`. When using functions, they are **always** at the top of the script!
``` BASH
function _<name_underscored_and_lowercase>()
{
<CODE TO RUN>
# variables that can be local should be local
local _<LOCAL_VARIABLE_NAME>
}
```
##### error tracing
A construct to trace error in your scripts looks like this:
``` BASH
set -euxEo pipefail
trap '_report_err $_ $LINENO $?' ERR
function _report_err()
{
echo "ERROR occurred :: source (hint) $1 ; line $2 ; exit code $3 ;;" >&2
<CODE TO RUN AFTERWARDS>
}
```
Please use it like this (copy-paste) to make errors streamlined. Remember: Remove `set -x` in the end. This of debugging purposes only.
##### comments and descriptiveness
Comments should be kept minimal and only describe non-obvious matters, i.e. not what the code does. Comments should start lowercase as most of them are not sentences. Make the code **self-descriptive** by using meaningful names! Make comments not longer than approximately 60 columns, then wrap the line.
A negative example:
``` BASH
# adds one to the first argument
# and print it to stdout
function _add_one()
{
# save the first variable
local FIRST=$1
# add one here
local RESULT=$(( _FIRST + 1 ))
# print it to stdout
echo "$_RESULT"
}
```
A positive example:
``` BASH
# writes result to stdout
function _add_one()
{
echo $(( $1 + 1 ))
}
