use #pragma once instead of foo*foo #define guards #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers 2012-07-18 19:07:51 +02:00			`#pragma once`

journalctl: fix ellipsization with PAGER=cat There are other reasons for not opening the pager then the --no-pager or --follow options (described below). If the pager is not used, messages must be ellipsized.

Add __attribute__((const, pure, format)) in various places I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls. 2013-05-03 04:51:50 +02:00			`#include "macro.h"`

tree-wide: merge pager_open_if_enabled() to the pager_open() Many subsystems define own pager_open_if_enabled() function which checks '--no-pager' command line argument and open pager depends on its value. All implementations of pager_open_if_enabled() are the same. Let's merger this function with pager_open() from the shared/pager.c and remove pager_open_if_enabled() from all subsytems to prevent code duplication. 2016-02-19 19:25:13 +01:00			`int pager_open(bool no_pager, bool jump_to_end);`
