Coding rules

General rules

  • In source code, your comments, variable names, .. must be written in English only (no other language is allowed).

  • Use a copyright header in each new source file with:

    • short description of file (one line),

    • date,

    • name,

    • e-mail,

    • license.

Example in C:

/*
 * weechat.c - core functions for WeeChat
 *
 * Copyright (C) 2015 Your Name <your@email.com>

 * GNU General Public License for more details.
 *
 * You should have received a copy of the GNU General Public License
 * along with WeeChat.  If not, see <http://www.gnu.org/licenses/>.
 */

C style

Some basic rules you must follow when you write C code:

  • Use 4 spaces for indentation. Don’t use tabs, they are evil.

  • Try to not exceed 80 chars by line, except if this is needed to increase readability.

  • Use comments /* comment */ (not C99-style comments like // comment).

  • Add a comment before any function, to explain what it does (always use a multi-line comment, even if description is very short).

Example:

/*
 * Checks if a string with boolean value is valid.
 *
 * Returns:
 *   1: boolean value is valid
 *   0: boolean value is NOT valid
 */

int
foo ()
{
    int i;

    /* one line comment */
    i = 1;

    /*
     * multi-line comment: this is a very long description about next block
     * of code
     */
    i = 2;
    printf ("%d\n", i);
}

  • Use explicit variable names, for example "nicks_count" instead of "n" or "nc". Exception: in for loops, where variables like "i" or "n" are OK.

  • Initialize local variables after declaration, in body of function, example: 

void
foo ()
{
    int nick_count, buffer_count;

    nick_count = 0;
    buffer_count = 1;
    /* ... */
}

  • Use parentheses to explicitly show how expression is evaluated, even if they are not required, for example: write x + (y * z) instead of x + y * z.

  • Place curly brackets { } alone on lines, and indent them with number of spaces used for line above opening curly bracket (the if in example): 

if (nicks_count == 1)
{
    /* something */
}

  • Use empty lines to separate many different blocks inside functions, and if possible add a comment for each one, like this: 

/*
 * Sends a message from out queue.
 */

void
irc_server_outqueue_send (struct t_irc_server *server)
{
    /* ... */

    /* send signal with command that will be sent to server */
    irc_server_send_signal (server, "irc_out",
                            server->outqueue[priority]->command,
                            server->outqueue[priority]->message_after_mod,
                            NULL);
    tags_to_send = irc_server_get_tags_to_send (server->outqueue[priority]->tags);
    irc_server_send_signal (server, "irc_outtags",
                            server->outqueue[priority]->command,
                            server->outqueue[priority]->message_after_mod,
                            (tags_to_send) ? tags_to_send : "");
    if (tags_to_send)
        free (tags_to_send);

    /* send command */
    irc_server_send (server, server->outqueue[priority]->message_after_mod,
                     strlen (server->outqueue[priority]->message_after_mod));
    server->last_user_message = time_now;

    /* start redirection if redirect is set */
    if (server->outqueue[priority]->redirect)
    {
        irc_redirect_init_command (server->outqueue[priority]->redirect,
                                   server->outqueue[priority]->message_after_mod);
    }

    /* ... */
}

  • Indent the if conditions, and use parentheses around conditions with an operator (not needed for single boolean), like this: 

if (something)
{
    /* something */
}
else
{
    /* something else */
}

if (my_boolean1 && my_boolean2 && (i == 10)
    && ((buffer1 != buffer2) || (window1 != window2)))
{
    /* something */
}
else
{
    /* something else */
}

  • Indent the switch statements like this: 

switch (string[0])
{
    case 'A':  /* first case */
        foo ("abc", "def");
        break;
    case 'B':  /* second case */
        bar (1, 2, 3);
        break;
    default:  /* other cases */
        baz ();
        break;
}

  • Use typedef for function prototypes but not for structures: 

typedef int (t_hook_callback_fd)(void *data, int fd);

struct t_hook_fd
{
    t_hook_callback_fd *callback;      /* fd callback                       */
    int fd;                            /* socket or file descriptor         */
    int flags;                         /* fd flags (read,write,..)          */
    int error;                         /* contains errno if error occurred  */
                                       /* with fd                           */
};

/* ... */

struct t_hook_fd *new_hook_fd;

new_hook_fd = malloc (sizeof (*new_hook_fd));

  • This Lisp code can be used in your ~/.emacs.el to indent properly if you are using Emacs as text editor: 

(add-hook 'c-mode-common-hook
          '(lambda ()
             (c-toggle-hungry-state t)
             (c-set-style "k&r")
             (setq c-basic-offset 4)
             (c-tab-always-indent t)
             (c-set-offset 'case-label '+)))

Core internals

Naming convention

Files

File names are composed by letters and hyphens, with format: xxx-yyyyy.[ch], where xxx is directory/component (can be abbreviation) and yyyyy a name for the file.

The main file of a directory may have same name as directory, for example irc.c in irc plugin.

Examples:

Directory Files 
 src/core/

weechat.c, wee-backtrace.c, wee-command.c, …

 
 src/gui/

gui-bar.c, gui-bar-item.c, gui-bar-window.c, …

 
 src/gui/curses/

gui-curses-bar.c, gui-curses-bar-window.c, gui-curses-chat.c, …

 
 src/plugins/

plugin.c, plugin-api.c, plugin-config.c, plugin-script.c, …

 
 src/plugins/irc/

irc.c, irc-bar-item.c, irc-buffer.c, …

 
 src/plugins/python/

weechat-python.c, weechat-python-api.c, …

The headers of C files have same name as file, for example wee-command.h for file wee-command.c.

Structures

Structures have name t_X_Y or t_X_Y_Z:

  • X: directory/component (can be abbreviation)

  • Y: end of file name

  • Z: name for structure (optional)

Example: an IRC nick (from src/plugins/irc/irc-nick.h):

struct t_irc_nick
{
    char *name;                     /* nickname                              */
    char *host;                     /* full hostname                         */
    char *prefixes;                 /* string with prefixes enabled for nick */
    char prefix[2];                 /* current prefix (higher prefix set in  */
                                    /* prefixes)                             */
    int away;                       /* 1 if nick is away                     */
    char *color;                    /* color for nickname in chat window     */
    struct t_irc_nick *prev_nick;   /* link to previous nick on channel      */
    struct t_irc_nick *next_nick;   /* link to next nick on channel          */
};

Variables

Global variables (outside functions) have name X_Y_Z:

  • X: directory/component (can be abbreviation)

  • Y: end of file name

  • Z: name for variable

Exception are variables for "last" node of a list, name is last_X (where X is name of variable, using singular form).

Example: windows (from src/gui/gui-window.c):

struct t_gui_window *gui_windows = NULL;        /* first window             */
struct t_gui_window *last_gui_window = NULL;    /* last window              */
struct t_gui_window *gui_current_window = NULL; /* current window           */

There is no naming convention for local variables (in functions). The only recommendation is that name is explicit (not too short).
Nevertheless, pointers to structures are often named ptr_xxxx, for example a pointer on a struct t_gui_buffer * will be: *ptr_buffer.

Functions

Naming convention for functions is the same as variables.

Example: creation of a new window (from src/gui/gui-window.c):

/*
 * Creates a new window.
 *
 * Returns pointer to new window, NULL if error.
 */

struct t_gui_window *
gui_window_new (struct t_gui_window *parent_window, struct t_gui_buffer *buffer,
                int x, int y, int width, int height,
                int width_pct, int height_pct)
{
    /* ... */

    return new_window;
}

Single thread

WeeChat is single threaded. That means every part of code should execute very fast, and that calls to functions like sleep are strictly forbidden (it is true for WeeChat core, but also C plugins and scripts).

If for some reasons you have to sleep a while, use hook_timer with a callback.

Doubly linked lists

Most of WeeChat linked lists are doubly linked lists: each node has pointer to previous and next node.

Example: list of buffers (from src/gui/gui-buffer.h):

struct t_gui_buffer
{
    /* data */

    /* ... */

    struct t_gui_buffer *prev_buffer;  /* link to previous buffer           */
    struct t_gui_buffer *next_buffer;  /* link to next buffer               */
};

Then the two list pointers, to the head and tail of list:

struct t_gui_buffer *gui_buffers = NULL;           /* first buffer          */
struct t_gui_buffer *last_gui_buffer = NULL;       /* last buffer           */

Color codes in strings

WeeChat uses own color codes in strings to display attributes (bold, underline, …) and colors on screen.

All attributes/colors are prefixed with a char in string, which can be:

  • 0x19: color code (followed by color code(s))

  • 0x1A: set attribute (followed by attribute on one char)

  • 0x1B: remove attribute (followed by attribute on one char)

  • 0x1C: reset (nothing after)

Allowed attributes are (one or more chars):

Plugin internals

The file src/plugins/weechat-plugin.h defines and exports all functions available in the API.

A structure called t_weechat_plugin is used to store info about plugin (filename, name, author, description, …) and all API functions, as pointers to WeeChat functions.

Then some macros are defined to call these functions.

For example, function hook_timer is defined in structure t_weechat_plugin like this:

struct t_hook *(*hook_timer) (struct t_weechat_plugin *plugin,
                              long interval,
                              int align_second,
                              int max_calls,
                              int (*callback)(void *data,
                                              int remaining_calls),
                              void *callback_data);

And the macro used to call this function is:

#define weechat_hook_timer(__interval, __align_second, __max_calls,     \
                           __callback, __data)                          \
    weechat_plugin->hook_timer(weechat_plugin, __interval,              \
                               __align_second, __max_calls,             \
                               __callback, __data)

So in a plugin, the call to function will be for example:

server->hook_timer_sasl = weechat_hook_timer (timeout * 1000,
                                              0, 1,
                                              &irc_server_timer_sasl_cb,
                                              server);

Git repository

Git repository is at this URL: https://github.com/weechat/weechat

Any patch for bug or new feature must be done on master branch, preferred way is a GitHub pull request. A patch can also be sent by e-mail (made with git diff or git format-patch).

Format of commit message is the following (to close a GitHub issue):

component: fix a problem (closes #123)

For a Savannah bug:

component: fix a problem (bug #12345)

Where component is one of following:

  • WeeChat core: core (files in root directory, po/ and src/, except src/plugins/)

  • documentation files: doc (files in directory doc/)

  • name of a plugin: irc, python, relay, … (files in directory src/plugins/)

Some rules to follow:

  • use only English

  • use infinitive form of verb

  • if commit is related to something in tracker, write it in parenthesis after the message, with this format:

    • GitHub: closes #123

    • Savannah: bug #12345, task #12345, patch #12345

Examples of commit messages:

irc: add command /unquiet (closes #36)
core: add callback "nickcmp" for nick comparison in buffers
irc: fix freeze when reading on socket with SSL enabled (bug #35097)
ruby: add detection of ruby version 1.9.3 in cmake
python: fix crash when unloading a script without pointer to interpreter
core: update Japanese translations (patch #7783)

Translations

Gettext

Gettext files are in directory po/.

If you want to initialize a new language, use command msginit. For example to create a file which is ready to translate to Dutch:

$ cd po
$ msginit -i weechat.pot -l nl_NL -o nl.po

Base language for WeeChat is English, so you must of course perfectly understand English in order to translate to your language.

When done, you have to check your file with script msgcheck.py (https://github.com/flashcode/msgcheck):

$ msgcheck.py xx.po
Build auto-generated files

Files in directory doc/XX/autogen/ are auto-generated by script doc/docgen.py.

Copy this python script to your python directory (for example ~/.weechat/python). Then you can load this script in your WeeChat, and setup path to your /doc directory:

/python load docgen.py
/set plugins.var.python.docgen.path "~/src/weechat/doc"

Then create this alias to build files:

/alias add doc /perl unload; /python unload; /ruby unload; /lua unload; /tcl unload; /guile unload; /javascript unload; /python load docgen.py; /wait 1ms /docgen

And use command /doc to build all files, for all languages.

Important
 When using command /doc, be sure all C plugins (irc, charset, …) are loaded, because files are built using data currently in memory.

Asciidoc

Asciidoc files are in directory doc/XX/ where XX is language (en, fr, de, it, …).

First make a copy of an English asciidoc file (in directory doc/en/), then work on it.

The translations missing in files are indicated by this string:

// TRANSLATION MISSING

You must translate whole file except links and special keywords for notes, warnings, … These words must be kept unchanged:

[[link_name]]
<<link_name>>

[NOTE]
[TIP]
[IMPORTANT]
[WARNING]
[CAUTION]

When there is a name after <<link_name>>, then you must translate it:

<<link_name,this text must be translated>>
