Contributing to pacman
======================
Please read 'submitting-patches' and 'translation-help' in the same directory
as this file.
Coding style
------------
1. All code should be indented with tabs. (Ignore the use of only spaces in
this file) By default, source files contain the following VIM modeline:
/* vim: set ts=2 sw=2 noet: */
2. When opening new blocks such as 'while', 'if', or 'for', leave the opening
brace on the same line as the beginning of the codeblock. The closing brace
gets its own line (the only exception being 'else'). Do not use extra
spaces around the parentheses of the block. ALWAYS use opening/closing
braces, even if it's just a one-line block.
for(lp = list; lp; lp = lp->next) {
newlist = _alpm_list_add(newlist, strdup(lp->data));
}
while(it) {
ptr = it->next;
if(fn) {
fn(it->data);
} else {
return(1);
}
free(it);
it = ptr;
}
3. When declaring a new function, put the opening and closing braces on their
own line. Also, when declaring a pointer, do not put a space between the
asterisk and the variable name.
pmlist_t *_alpm_list_add(pmlist_t *list, void *data)
{
pmlist_t *ptr, *lp;
ptr = list;
if(ptr == NULL) {
...
}
4. Comments should be ANSI-C89 compliant. That means no "// Comment" style;
use only "/* Comment */" style.
5. Return statements should be written like a function call.
return(0);
NOT
return 0;
6. The sizeof() operator should accept a type, not a value. (TODO: in certain
cases, it may be better- should this be a set guideline? Read "The Practice
of Programming")
sizeof(alpm_list_t);
NOT
sizeof(*mylist);
Other Concerns
--------------
Currently our #include usage is in messy shape, but this is no reason to
continue down this messy path. When adding an include to a file, follow this
general pattern, including blank lines:
#include "config.h"
#include <standardheader.h>
#include <another.h>
#include <...>
Follow this with some more headers, depending on whether the file is in libalpm
or pacman proper. For libalpm:
/* libalpm */
#include "yourfile.h"
#include "alpm_list.h"
#include "anythingelse.h"
For pacman:
#include <alpm.h>
#include <alpm_list.h>
/* pacman */
#include "yourfile.h"
#include "anythingelse.h"
