InkBox project code contributing guidelines

This page contains code contributing guidelines one must follow for their code to be merged in one of the source repositories of the InkBox project. When writing code, you shall remember one word: consistency.

Before starting and/or pushing to a repository

• If the repository you are working on is a fork, please ensure that it is up-to-date with upstream before making changes.
• Make sure that no build artifacts are staged for a commit it before it's too late. .gitignore is your friend.

Language-independent

Indentation

One indent must be equivalent to 4 spaces or one tabulation.

Newline at end of file

Files must contain an empty newline at the end. If you are using Visual Studio Code, enable this: https://stackoverflow.com/questions/44704968/visual-studio-code-insert-newline-at-the-end-of-files/44704969#44704969

English

Check your spelling before committing.

• Pro tip: Never commit your code without testing and reviewing it (whichever comes first).
• Pro tip: In English, sentences start with a capital letter and finish with a period.

Comments

Comments must start with a capital letter.

clang-format

Do NOT use clang-format.

C/C++

• No unnecessary includes
• One-line comments:

// Hi, this is a comment

• Multi-line comments:

/*
    Hi, this is a
    multi-line comment
*/

C

Variables and function names

Use snake_case when programming in C. This doesn't apply if you are inserting C code into a C++ project. In this case, follow only the C++ guidelines.

if conditions

if(thing) {
    do_thing();
}
else {
    do_other_thing();
}

C++

Variables and function names

Use camelCase in C++. This applies also if you are inserting C into C++ code.

if conditions

if(thing) {
    doThing();
}
else {
    doOtherThing();
}

Bourne-Again SHell (bash) and similar

Variables and function names

Use snake_case or CAPITAL_SNAKE_CASE.

• Variables must be declared like this: var="test". For integer variables, they must be declared like this: var=0.
• Variables must be accessed like this: echo "${var}". For integer variables, they may be accessed like this: echo ${var}.
• Files names in variables must be put in double quotes, like this: if [ -f "${file}" ]; then

if conditions

if [ "${var}" == "test" ]; then
    do_thing
else
    do_other_thing
fi

JSON

Properties names

Use PascalCase.
