8 This project is programmed using the Linux kernel coding style:
10 https://www.kernel.org/doc/html/latest/process/coding-style.html
12 Please use the same style for any code contributions, thanks!
14 In some exceptional cases deviations from the above coding guidelines are
15 OK (in order to meet Qt/C++ related guidelines, for example).
21 - In order to contribute you should ideally clone the git repository and
22 let us know (preferably via IRC, or via the mailing list) from where to
23 pull/review your changes. You can use github.com, or any other public git
26 - Alternatively, patches can be sent to the development mailinglist at
27 sigrok-devel@lists.sourceforge.net (please subscribe to the list first).

35 - Consistently use g_try_malloc() / g_try_malloc0(). Do not use standard
36 malloc()/calloc() if it can be avoided (sometimes other libs such
37 as libftdi can return malloc()'d memory, for example).
39 - Always properly match allocations with the proper *free() functions. If
40 glib's g_try_malloc()/g_try_malloc0() was used, use g_free() to free the
41 memory. Otherwise use standard free(). Never use the wrong function!
43 - Never use g_malloc() or g_malloc0(). These functions do not return nullptr
44 if not enough memory is available but rather lead to an exit() or segfault
45 instead. This behaviour is not acceptable.
46 Use g_try_malloc()/g_try_malloc0() instead and check the return value.
48 - Use glib's gboolean / TRUE / FALSE for boolean types consistently.
49 Do not use <stdbool.h> and its true / false, and do not invent private
50 definitions for this either.
52 - Consistently use the same naming convention for #include guards in headers:
53 <PROJECTNAME>_<PATH_TO_FILE>_<FILE>
54 This ensures that all #include guards are always unique and consistent.
55 Example: PULSEVIEW_PV_VIEW_RULER_H
57 - Consistently use the same naming convention for functions, if appropriate:
59 Getter/setter function names should usually end with "_get" or "_set".
60 Functions creating new "objects" should end with "_new".
61 Functions destroying "objects" should end with "_destroy".
62 Functions adding or removing items (e.g. from lists) should end with
63 either "_add" or "_remove".
64 Functions operating on all items from a list (not on only one of them),
65 should end with "_all", e.g. "_remove_all", "_get_all", and so on.
66 Use "_remove_all" in favor of "_clear" for consistency.
68 - In Doxygen comments, put an empty line between the block of @param lines
69 and the final @return line. The @param lines themselves (if there is more
70 than one) are not separated by empty lines.
72 - Use QIcon::fromTheme() for icons that are included in the freedesktop.org
73 icon naming specification. Do NOT use it for all other icons.
