HACKING
-------------------------------------------------------------------------------
Coding style
------------
This project is programmed using the Linux kernel coding style:
https://www.kernel.org/doc/html/latest/process/coding-style.html
Please use the same style for any code contributions, thanks!
Contributions
-------------
- In order to contribute you should ideally clone the git repository and
let us know (preferably via IRC, or via the mailing list) from where to
pull/review your changes. You can use github.com, or any other public git
hosting site.
- Alternatively, patches can be sent to the development mailinglist at
sigrok-devel@lists.sourceforge.net (please subscribe to the list first).
https://lists.sourceforge.net/lists/listinfo/sigrok-devel
Random notes
------------
- Consistently use g_try_malloc() / g_try_malloc0(). Do not use standard
malloc()/calloc() if it can be avoided (sometimes other libs such
as libftdi can return malloc()'d memory, for example).
- Always properly match allocations with the proper *free() functions. If
glib's g_try_malloc()/g_try_malloc0() was used, use g_free() to free the
memory. Otherwise use standard free(). Never use the wrong function!
- Never use g_malloc() or g_malloc0(). These functions do not return NULL
if not enough memory is available but rather lead to an exit() or segfault
instead. This behaviour is not acceptable.
Use g_try_malloc()/g_try_malloc0() instead and check the return value.
- You should never print any messages (neither to stdout nor stderr nor
elsewhere) "manually" via e.g. printf() or g_log() or similar functions.
Only sr_err()/sr_warn()/sr_info()/sr_dbg()/sr_spew() should be used.
- Use glib's gboolean / TRUE / FALSE for boolean types consistently.
Do not use <stdbool.h> and its true / false, and do not invent private
definitions for this either.
- Consistently use the same naming convention for #include guards in headers:
<PROJECTNAME>_<PATH_TO_FILE>_<FILE>
This ensures that all #include guards are always unique and consistent.
Example: SIGROK_CLI_SIGROK_CLI_H
- Consistently use the same naming convention for functions, if appropriate:
Getter/setter function names should usually end with "_get" or "_set".
Functions creating new "objects" should end with "_new".
Functions destroying "objects" should end with "_destroy".
Functions adding or removing items (e.g. from lists) should end with
either "_add" or "_remove".
Functions operating on all items from a list (not on only one of them),
should end with "_all", e.g. "_remove_all", "_get_all", and so on.
Use "_remove_all" in favor of "_clear" for consistency.
- In Doxygen comments, put an empty line between the block of @param lines
and the final @return line. The @param lines themselves (if there is more
than one) are not separated by empty lines.
Release engineering
-------------------
See

for a list of items that need to be done when releasing a new tarball.
