From ea19289bc82351b7ac20ea2fd877e2bdde97ae34 Mon Sep 17 00:00:00 2001 From: Paul Tan Date: Tue, 21 Apr 2015 12:06:27 +0800 Subject: path.c: implement xdg_config_home() The XDG base dir spec[1] specifies that configuration files be stored in a subdirectory in $XDG_CONFIG_HOME. To construct such a configuration file path, home_config_paths() can be used. However, home_config_paths() combines distinct functionality: 1. Retrieve the home git config file path ~/.gitconfig 2. Construct the XDG config path of the file specified by `file`. This function was introduced in commit 21cf3227 ("read (but not write) from $XDG_CONFIG_HOME/git/config file"). While the intention of the function was to allow the home directory configuration file path and the xdg directory configuration file path to be retrieved with one function call, the hard-coding of the path ~/.gitconfig prevents it from being used for other configuration files. Furthermore, retrieving a file path relative to the user's home directory can be done with expand_user_path(). Hence, it can be seen that home_config_paths() introduces unnecessary complexity, especially if a user just wants to retrieve the xdg config file path. As such, implement a simpler function xdg_config_home() for constructing the XDG base dir spec configuration file path. This function, together with expand_user_path(), can replace all uses of home_config_paths().

Since its use will just add unnecessary complexity to the code, remove it.
