\title{Get or set Git configuration}
\usage{
git_config(repo = ".")

git_config_global()

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

git_config_global_set(name, value)
}
\arguments{
\item{repo}{The path to the git repository. If the directory is not a
repository, parent directories are considered (see \link{git_find}). To disable
this search, provide the filepath protected with \code{\link[=I]{I()}}. When using this
parameter, always explicitly call by name (i.e. \verb{repo = }) because future
versions of gert may have additional parameters.}

\item{name}{Name of the option to set}

\item{value}{Value to set. Must be a string, logical, number or \code{NULL} (to
unset).}
}
\value{
\itemize{
\item \code{git_config()}: a \code{data.frame} of the Git options "in force" in the context
of \code{repo}, one row per option. The \code{level} column reveals whether the
option is determined from global or local config.
\item \code{git_config_global()}: a \code{data.frame}, as for \code{git_config()}, except only
for global Git options.
\item \code{git_config_set()}, \code{git_config_global_set()}: The previous value of
\code{name} in local or global config, respectively. If this option was
previously unset, returns \code{NULL}. Returns invisibly.
}
}
\description{
Get or set Git options, as \verb{git config} does on the command line. \strong{Global}
settings affect all of a user's Git operations (\verb{git config --global}),
whereas \strong{local} settings are scoped to a specific repository (\verb{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.\tabular{lll}{
    \tab \strong{local} \tab \strong{global} \cr
   get \tab \code{git_config()} \tab \code{git_config_global()} \cr
   set \tab \code{git_config_set()} \tab \code{git_config_global_set()} \cr
}
}
\note{
All entries in the \code{name} column are automatically normalised to
lowercase (see
\url{https://libgit2.org/libgit2/#HEAD/type/git_config_entry} for details).
