Git trees

The Git trees API lets you read and write tree objects to your Git database on GitHub Enterprise Server.

About the Git trees API

A Git tree object creates the hierarchy between files in a Git repository. You can use the Git tree object to create the relationship between directories and the files they contain. These endpoints allow you to read and write tree objects to your Git database on GitHub Enterprise Server.

Create a tree

Works with GitHub Apps

The tree creation API accepts nested entries. If you specify both a tree and a nested path modifying that tree, this endpoint will overwrite the contents of the tree with the new path contents, and create a new tree structure.

If you use this endpoint to add, delete, or modify the file contents in a tree, you will need to commit the tree and then update a branch to point to the commit. For more information see "Create a commit" and "Update a reference."

Returns an error if you try to delete a file that does not exist.

Parameters

Headers

Name, Type, Description

acceptstring

Setting to application/vnd.github+json is recommended.

Path parameters

Name, Type, Description

ownerstringRequired

The account owner of the repository. The name is not case sensitive.

repostringRequired

The name of the repository. The name is not case sensitive.

Body parameters

Name, Type, Description

treearray of objectsRequired

Objects (of path, mode, type, and sha) specifying a tree structure.

Properties of tree

Name, Type, Description
`path`string The file referenced in the tree.
`mode`string The file mode; one of `100644` for file (blob), `100755` for executable (blob), `040000` for subdirectory (tree), `160000` for submodule (commit), or `120000` for a blob that specifies the path of a symlink. Can be one of: `100644`, `100755`, `040000`, `160000`, `120000`
`type`string Either `blob`, `tree`, or `commit`. Can be one of: `blob`, `tree`, `commit`
`sha`string or null The SHA1 checksum ID of the object in the tree. Also called `tree.sha`. If the value is `null` then the file will be deleted. Note: Use either `tree.sha` or `content` to specify the contents of the entry. Using both `tree.sha` and `content` will return an error.
`content`string The content you want this file to have. GitHub will write this blob out and use that SHA for this entry. Use either this, or `tree.sha`. Note: Use either `tree.sha` or `content` to specify the contents of the entry. Using both `tree.sha` and `content` will return an error.

base_treestring

The SHA1 of an existing Git tree object which will be used as the base for the new tree. If provided, a new Git tree object will be created from entries in the Git tree object pointed to by base_tree and entries defined in the tree parameter. Entries defined in the tree parameter will overwrite items from base_tree with the same path. If you're creating new changes on a branch, then normally you'd set base_tree to the SHA1 of the Git tree object of the current latest commit on the branch you're working on. If not provided, GitHub will create a new Git tree object from only the entries defined in the tree parameter. If you create a new commit pointing to such a tree, then all files which were a part of the parent commit's tree and were not defined in the tree parameter will be listed as deleted by the new commit.

Get a tree

Works with GitHub Apps

Returns a single tree using the SHA1 value for that tree.

If truncated is true in the response then the number of items in the tree array exceeded our maximum limit. If you need to fetch more items, use the non-recursive method of fetching trees, and fetch one sub-tree at a time.

Note: The limit for the tree array is 100,000 entries with a maximum size of 7 MB when using the recursive parameter.

Parameters

Headers
Name, Type, Description
`accept`string Setting to `application/vnd.github+json` is recommended.
Path parameters
Name, Type, Description
`owner`stringRequired The account owner of the repository. The name is not case sensitive.
`repo`stringRequired The name of the repository. The name is not case sensitive.
`tree_sha`stringRequired
Query parameters
Name, Type, Description
`recursive`string Setting this parameter to any value returns the objects or subtrees referenced by the tree specified in `:tree_sha`. For example, setting `recursive` to any of the following will enable returning objects or subtrees: `0`, `1`, `"true"`, and `"false"`. Omit this parameter to prevent recursively returning objects or subtrees.
