Helper functions for working with Git and fetching the tags/commits we care about.

Summary

Types

commit_info()

Functions

add!(repo, args)
blob_oid(repo, contents)

The blob OID contents would hash to.

commit!(repo, args)
commit_subject!(repo, sha)

The subject line of a commit.

commit_tree!(repo, base_ref, files, message)

Commits files (a map of repo-relative path to contents) on top of base_ref using a temporary index, leaving the working tree untouched. Returns the new commit's SHA.

commits_touching!(repo, path, limit)

First-parent commit SHAs of HEAD that touch path, newest first.

current_branch!(repo)

The name of the currently checked out branch.

get_commit_info(repo, since_tag \\ :all, opts \\ [])

Commit info since a tag (or all commits), newest first.

hooks_path(repo)
init!(repo_path)
initial_commit_message()
oid_at(repo, ref, path)

The blob OID at ref:path, or nil when absent. Resolved from tree objects alone, so it never fetches blobs on a partial clone.

parse_git_log(git_log_output)
push!(repo, source, target)

Force-pushes a commit or tag ref to origin.

remote_branch_tree(repo, branch)

The tree hash of the origin remote's branch, or nil when the branch does not exist there.

remote_tags(repo)

The tag names present on the origin remote, or the local tags when there is no reachable remote.

show(repo, ref, path)

The contents of path at ref, or :error if it does not exist there.

tag!(repo, current_version)
tag_exists?(repo, tag)
tags(repo)
tags(repo, prefix)

All tags starting with prefix, newest version first.

Types

commit_info()

@type commit_info() :: %{
  hash: String.t(),
  message: String.t(),
  author_name: String.t(),
  author_email: String.t()
}

Functions

add!(repo, args)

@spec add!(Git.Repository.t(), [String.t()]) :: String.t()

blob_oid(repo, contents)

@spec blob_oid(Git.Repository.t(), String.t()) :: String.t()

The blob OID contents would hash to.

commit!(repo, args)

@spec commit!(Git.Repository.t(), [String.t()]) :: String.t()

commit_subject!(repo, sha)

@spec commit_subject!(Git.Repository.t(), String.t()) :: String.t()

The subject line of a commit.

commit_tree!(repo, base_ref, files, message)

@spec commit_tree!(
  Git.Repository.t(),
  String.t(),
  %{required(String.t()) => String.t()},
  String.t()
) ::
  String.t()

Commits files (a map of repo-relative path to contents) on top of base_ref using a temporary index, leaving the working tree untouched. Returns the new commit's SHA.

commits_touching!(repo, path, limit)

@spec commits_touching!(Git.Repository.t(), String.t(), pos_integer()) :: [String.t()]

First-parent commit SHAs of HEAD that touch path, newest first.

current_branch!(repo)

@spec current_branch!(Git.Repository.t()) :: String.t()

The name of the currently checked out branch.

get_commit_info(repo, since_tag \\ :all, opts \\ [])

@spec get_commit_info(Git.Repository.t(), String.t() | :all, Keyword.t()) :: [
  commit_info()
]

Commit info since a tag (or all commits), newest first.

Options:

  • :paths - pathspecs restricting which commits count (git pathspec syntax, so :^dir entries exclude).
  • :first_parent - follow only the first parent of merge commits.

hooks_path(repo)

@spec hooks_path(Git.Repository.t()) :: String.t() | no_return()

init!(repo_path)

@spec init!(String.t()) :: Git.Repository.t()

initial_commit_message()

oid_at(repo, ref, path)

@spec oid_at(Git.Repository.t(), String.t(), String.t()) :: String.t() | nil

The blob OID at ref:path, or nil when absent. Resolved from tree objects alone, so it never fetches blobs on a partial clone.

parse_git_log(git_log_output)

@spec parse_git_log(String.t()) :: [commit_info()]

push!(repo, source, target)

@spec push!(Git.Repository.t(), String.t(), String.t()) :: :ok

Force-pushes a commit or tag ref to origin.

remote_branch_tree(repo, branch)

@spec remote_branch_tree(Git.Repository.t(), String.t()) :: String.t() | nil

The tree hash of the origin remote's branch, or nil when the branch does not exist there.

remote_tags(repo)

@spec remote_tags(Git.Repository.t()) :: MapSet.t(String.t())

The tag names present on the origin remote, or the local tags when there is no reachable remote.

show(repo, ref, path)

@spec show(Git.Repository.t(), String.t(), String.t()) :: {:ok, String.t()} | :error

The contents of path at ref, or :error if it does not exist there.

tag!(repo, current_version)

@spec tag!(Git.Repository.t(), String.t() | [String.t()]) :: String.t()

tag_exists?(repo, tag)

@spec tag_exists?(Git.Repository.t(), String.t()) :: boolean()

tags(repo)

@spec tags(Git.Repository.t()) :: [String.t()]

tags(repo, prefix)

@spec tags(Git.Repository.t(), String.t()) :: [String.t()]

All tags starting with prefix, newest version first.

Unlike tags/1, returns an empty list when nothing matches, so callers can treat "never released" as a normal state.
