At the moment, building WeeChat triggers several thousand -Wstrict-prototypes
diagnostics. This is due to its source code using an empty argument list for
functions and function pointers that take no arguments, instead of explicitly
declaring that they take no arguments by using a void list.
This commit replaces all empty argument lists with a void list.
Note that Ruby's headers also suffer the same problem, which WeeChat can't
do anything to fix. Thus, building WeeChat with the Ruby plugin enabled
will still issue approximately 30 such diagnostics.
The API functions `command` and `command_options` (when `split_newline` = 0,
which is the default value) don't split on newline and then the first line is
executed and the subsequent lines (after "\n") are ignored.
There are no changes when the input has multiple lines filled by the user: the
split is done and multiple commands are executed (for example if the user is
pasting multiple commands to execute).
Options moved from irc.conf to weechat.conf:
* "irc.look.nick_color_force" moved to "weechat.look.nick_color_force"
* "irc.look.nick_color_hash" moved to "weechat.look.nick_color_hash"
* "irc.look.nick_color_stop_chars" moved to
"weechat.look.nick_color_stop_chars"
New info (for API function "info_get"):
* "nick_color" (replaces "irc_nick_color")
* "nick_color_name" (replaced "irc_nick_color_name")
Info "irc_nick_color" and "irc_nick_color_name" are now deprecated.
And a bug has been fixed in nick coloring: stop chars are removed before
looking at a forced color.
This pointer is the first argument received by callbacks, and the
existing argument "data" is now automatically freed by WeeChat when the
object containing the callback is removed.
With this new pointer, the linked list of callbacks in scripts has been
removed. This will improve speed of scripts (using a lot of hooks),
reduce memory used by scripts and reduce time to unload scripts.
