List the contents of a tree object

Traverse the entries in a tree and its subtrees. Akin to the 'git ls-tree' command.

Usage

ls_tree(tree = NULL, repo = ".", recursive = TRUE)

Arguments

tree

default (NULL) is the tree of the last commit in repo. Can also be a git_tree object or a character that identifies a tree in the repository (see ‘Examples’).

repo

never used if tree is a git_tree object. A git_repository object, or a path (default = '.') to a repository.

recursive

default is to recurse into sub-trees.

Value

A data.frame with the following columns:

mode

UNIX file attribute of the tree entry

type

type of object

sha

sha of the object

path

path relative to the root tree

name

filename of the tree entry

len

object size of blob (file) entries. NA for other objects.

Examples

if (FALSE) { # \dontrun{
## Initialize a temporary repository
path <- tempfile(pattern="git2r-")
dir.create(path)
dir.create(file.path(path, "subfolder"))
repo <- init(path)

## Create a user
config(repo, user.name = "Alice", user.email = "alice@example.org")

## Create three files and commit
writeLines("First file",  file.path(path, "example-1.txt"))
writeLines("Second file", file.path(path, "subfolder/example-2.txt"))
writeLines("Third file",  file.path(path, "example-3.txt"))
add(repo, c("example-1.txt", "subfolder/example-2.txt", "example-3.txt"))
commit(repo, "Commit message")

## Traverse tree entries and its subtrees.
## Various approaches that give identical result.
ls_tree(tree = tree(last_commit(path)))
ls_tree(tree = tree(last_commit(repo)))
ls_tree(repo = path)
ls_tree(repo = repo)

## Skip content in subfolder
ls_tree(repo = repo, recursive = FALSE)

## Start in subfolder
ls_tree(tree = "HEAD:subfolder", repo = repo)
} # }
