== Guidelines

smolbote is written under the C++17 standard, without any compiler-specific
extensions. Source code should be kept as platform-agnostic as possible.

=== General
* All behaviour, where possible, should be configurable.
* Configuration is stored in plaintext files, and option names should be as
  self-descriptive as possible.
* Use sane defaults. Normally, the program should "just work".

=== Qt
* Check pointers with Q_CHECK_PTR.
* Use the Qt5 signal/slot syntax (&Class::method) over the old string-based
  syntax (SIGNAL/SLOT). This enables compile-time connect checks.
* Prefer QVector over QList: http://lists.qt-project.org/pipermail/development/2017-March/029040.html

=== Setting linker
Meson has no environment variable to set the linker (link:https://github.com/mesonbuild/meson/issues/3597[issue]).

Instead, this can be done using the cpp_link_args:
[source, sh]
----
build% meson configure -Dcpp_link_args='-fuse-ld=gold'
----

=== clazy
You can use https://github.com/KDE/clazy[clazy] to check Qt semantics.

clazy is a drop-in replacement for clang. To set check levels, set the
CLAZY_CHECKS environment variable to 'level0,level1', etc.

== Licensing
Smolbote is licensed under GPLv3 _only_, and explicitly does not use any
self-updating "-or-later" licensing. Your code needs to be compatible with it,
and have a license header in the style used by the project.

Interfaces (located in include/) should be licensed under MIT. This is to allow
more license compatibility for plugins.

== Style
There is a clang-format style in .clang-format.

== Format patch for email

[source, sh]
----
git format-patch $from..$to
----

This will give you one patch per commit. If you want to merge all of them into
a single patch, you can merge the commits using rebase:

[source, sh]
----
git rebase --interactive
----

Alternatively, replay all your commits from the commit before $from on a new
branch:

[source, sh]
----
git branch delivery X
git checkout delivery
git merge --squash master
git format-patch HEAD
----

Email patches to _aqua at iserlohn dash fortress dot net_.
