git_config: Get or set Git configuration

In gert: Simple Git Client for R

Get or set Git configuration

Description

Get or set Git options, as ⁠git config⁠ does on the command line. Global settings affect all of a user's Git operations (⁠git config --global⁠), whereas local settings are scoped to a specific repository (⁠git config --local⁠). When both exist, local options always win. Four functions address the four possible combinations of getting vs setting and global vs. local.

	local	global
get	git_config()	git_config_global()
set	git_config_set()	git_config_global_set()

Usage

git_config(repo = ".")

git_config_global()

git_config_set(name, value, repo = ".")

git_config_global_set(name, value)

Arguments

repo	The path to the git repository. If the directory is not a repository, parent directories are considered (see git_find). To disable this search, provide the filepath protected with I(). When using this parameter, always explicitly call by name (i.e. ⁠repo = ⁠) because future versions of gert may have additional parameters.
name	Name of the option to set
value	Value to set. Must be a string, logical, number or NULL (to unset).

Value

• git_config(): a data.frame of the Git options "in force" in the context of repo, one row per option. The level column reveals whether the option is determined from global or local config.

• git_config_global(): a data.frame, as for git_config(), except only for global Git options.

• git_config_set(), git_config_global_set(): The previous value of name in local or global config, respectively. If this option was previously unset, returns NULL. Returns invisibly.

Note

All entries in the name column are automatically normalised to lowercase (see https://libgit2.org/libgit2/#HEAD/type/git_config_entry for details).

Examples

# Set and inspect a local, custom Git option
r <- file.path(tempdir(), "gert-demo")
git_init(r)

previous <- git_config_set("aaa.bbb", "ccc", repo = r)
previous
cfg <- git_config(repo = r)
subset(cfg, level == "local")
cfg$value[cfg$name == "aaa.bbb"]

previous <- git_config_set("aaa.bbb", NULL, repo = r)
previous
cfg <- git_config(repo = r)
subset(cfg, level == "local")
cfg$value[cfg$name == "aaa.bbb"]

unlink(r, recursive = TRUE)

## Not run: 
# Set global Git options
