R Documentation

Push and pull

Description

Functions to connect with a git server (remote) to fetch or push changes. The 'credentials' package is used to handle authentication, the credentials vignette explains the various authentication methods for SSH and HTTPS remotes.

Usage

git_fetch(
  remote = NULL,
  refspec = NULL,
  password = askpass,
  ssh_key = NULL,
  prune = FALSE,
  verbose = interactive(),
  repo = "."
)

git_remote_ls(
  remote = NULL,
  password = askpass,
  ssh_key = NULL,
  verbose = interactive(),
  repo = "."
)

git_push(
  remote = NULL,
  refspec = NULL,
  set_upstream = NULL,
  password = askpass,
  ssh_key = NULL,
  mirror = FALSE,
  force = FALSE,
  verbose = interactive(),
  repo = "."
)

git_clone(
  url,
  path = NULL,
  branch = NULL,
  password = askpass,
  ssh_key = NULL,
  bare = FALSE,
  mirror = FALSE,
  verbose = interactive()
)

git_pull(remote = NULL, rebase = FALSE, ..., repo = ".")

Arguments

`remote`	Optional. Name of a remote listed in `git_remote_list()`. If unspecified and the current branch is already tracking branch a remote branch, that remote is honored. Otherwise, defaults to `origin`.
`refspec`	string with mapping between remote and local refs. Default uses the default refspec from the remote, which usually fetches all branches.
`password`	a string or a callback function to get passwords for authentication or password protected ssh keys. Defaults to askpass which checks `getOption('askpass')`.
`ssh_key`	path or object containing your ssh private key. By default we look for keys in `ssh-agent` and credentials::ssh_key_info.
`prune`	delete tracking branches that no longer exist on the remote, or are not in the refspec (such as pull requests).
`verbose`	display some progress info while downloading
`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.
`set_upstream`	change the branch default upstream to `remote`. If `NULL`, this will set the branch upstream only if the push was successful and if the branch does not have an upstream set yet.
`mirror`	use the `--mirror` flag
`force`	use the `--force` flag
`url`	remote url. Typically starts with `⁠https://github.com/⁠` for public repositories, and `⁠https://yourname@github.com/⁠` or `⁠git@github.com/⁠` for private repos. You will be prompted for a password or pat when needed.
`path`	Directory of the Git repository to create.
`branch`	name of branch to check out locally
`bare`	use the `--bare` flag
`rebase`	if TRUE we try to rebase instead of merge local changes. This is not possible in case of conflicts (you will get an error).
`...`	arguments passed to git_fetch

Details

Use git_fetch() and git_push() to sync a local branch with a remote branch. Here git_pull() is a wrapper for git_fetch() which then tries to fast-forward the local branch after fetching.

Examples

{# Clone a small repository
git_dir <- file.path(tempdir(), 'antiword')
git_clone('https://github.com/ropensci/antiword', git_dir)

# Change into the repo directory
olddir <- getwd()
setwd(git_dir)

# Show some stuff
git_log()
git_branch_list()
git_remote_list()

# Add a file
write.csv(iris, 'iris.csv')
git_add('iris.csv')

# Commit the change
jerry <- git_signature("Jerry", "jerry@hotmail.com")
git_commit('added the iris file', author = jerry)

# Now in the log:
git_log()

# Cleanup
setwd(olddir)
unlink(git_dir, recursive = TRUE)
}
