almost never be used by "regular" git code that is looking up
configuration variables. It is intended for advanced callers like
`git-config`, which are intentionally tweaking the normal config-lookup
-process. It takes one extra parameter:
+process. It takes two extra parameters:
`filename`::
If this parameter is non-NULL, it specifies the name of a file to
parse for configuration, rather than looking in the usual files. Regular
`git_config` defaults to `NULL`.
+`respect_includes`::
+Specify whether include directives should be followed in parsed files.
+Regular `git_config` defaults to `1`.
+
There is a special version of `git_config` called `git_config_early`.
This version takes an additional parameter to specify the repository
config, instead of having it looked up via `git_path`. This is useful
Similar to `git_config_string`, but expands `~` or `~user` into the
user's home directory when found at the beginning of the path.
+Include Directives
+------------------
+
+By default, the config parser does not respect include directives.
+However, a caller can use the special `git_config_include` wrapper
+callback to support them. To do so, you simply wrap your "real" callback
+function and data pointer in a `struct config_include_data`, and pass
+the wrapper to the regular config-reading functions. For example:
+
+-------------------------------------------
+int read_file_with_include(const char *file, config_fn_t fn, void *data)
+{
+ struct config_include_data inc = CONFIG_INCLUDE_INIT;
+ inc.fn = fn;
+ inc.data = data;
+ return git_config_from_file(git_config_include, file, &inc);
+}
+-------------------------------------------
+
+`git_config` respects includes automatically. The lower-level
+`git_config_from_file` does not.
