# Retrives status of a git repo from a directory under its working tree.
#
## Usage: gitstatus_query [OPTION]... NAME
#
# -d STR Directory to query. Defaults to the current directory. Has no effect if GIT_DIR
# is set.
# -c STR Callback function to call once the results are available. Called only after
# gitstatus_query returns 0 with VCS_STATUS_RESULT=tout.
# -t FLOAT Timeout in seconds. Will block for at most this long. If no results are
# available by then: if -c isn't specified, will return 1; otherwise will set
# VCS_STATUS_RESULT=tout and return 0.
# -p Don't compute anything that requires reading Git index. If this option is used,
# the following parameters will be 0: VCS_STATUS_INDEX_SIZE,
# VCS_STATUS_{NUM,HAS}_{STAGED,UNSTAGED,UNTRACKED,CONFLICTED}.
#
# On success sets VCS_STATUS_RESULT to one of the following values:
#
# tout Timed out waiting for data; will call the user-specified callback later.
# norepo-sync The directory isn't a git repo.
# ok-sync The directory is a git repo.
#
# When the callback is called VCS_STATUS_RESULT is set to one of the following values:
#
# norepo-async The directory isn't a git repo.
# ok-async The directory is a git repo.
#
# If VCS_STATUS_RESULT is ok-sync or ok-async, additional variables are set:
#
# VCS_STATUS_WORKDIR Git repo working directory. Not empty.
# VCS_STATUS_COMMIT Commit hash that HEAD is pointing to. Either 40 hex digits or
# empty if there is no HEAD (empty repo).
# VCS_STATUS_LOCAL_BRANCH Local branch name or empty if not on a branch.
# VCS_STATUS_REMOTE_NAME The remote name, e.g. "upstream" or "origin".
# VCS_STATUS_REMOTE_BRANCH Upstream branch name. Can be empty.
# VCS_STATUS_REMOTE_URL Remote URL. Can be empty.
# VCS_STATUS_ACTION Repository state, A.K.A. action. Can be empty.
# VCS_STATUS_INDEX_SIZE The number of files in the index.
# VCS_STATUS_NUM_STAGED The number of staged changes.
# VCS_STATUS_NUM_CONFLICTED The number of conflicted changes.
# VCS_STATUS_NUM_UNSTAGED The number of unstaged changes.
# VCS_STATUS_NUM_UNTRACKED The number of untracked files.
# VCS_STATUS_HAS_STAGED 1 if there are staged changes, 0 otherwise.
# VCS_STATUS_HAS_CONFLICTED 1 if there are conflicted changes, 0 otherwise.
# VCS_STATUS_HAS_UNSTAGED 1 if there are unstaged changes, 0 if there aren't, -1 if
# unknown.
# VCS_STATUS_NUM_STAGED_NEW The number of staged new files. Note that renamed files
# are reported as deleted plus new.
# VCS_STATUS_NUM_STAGED_DELETED The number of staged deleted files. Note that renamed files
# are reported as deleted plus new.
# VCS_STATUS_NUM_UNSTAGED_DELETED The number of unstaged deleted files. Note that renamed files
# are reported as deleted plus new.
# VCS_STATUS_HAS_UNTRACKED 1 if there are untracked files, 0 if there aren't, -1 if
# unknown.
# VCS_STATUS_COMMITS_AHEAD Number of commits the current branch is ahead of upstream.
# Non-negative integer.
# VCS_STATUS_COMMITS_BEHIND Number of commits the current branch is behind upstream.
# Non-negative integer.
# VCS_STATUS_STASHES Number of stashes. Non-negative integer.
# VCS_STATUS_TAG The last tag (in lexicographical order) that points to the same
# commit as HEAD.
# VCS_STATUS_PUSH_REMOTE_NAME The push remote name, e.g. "upstream" or "origin".
# VCS_STATUS_PUSH_REMOTE_URL Push remote URL. Can be empty.
# VCS_STATUS_PUSH_COMMITS_AHEAD Number of commits the current branch is ahead of push remote.
# Non-negative integer.
# VCS_STATUS_PUSH_COMMITS_BEHIND Number of commits the current branch is behind push remote.
# Non-negative integer.
# VCS_STATUS_NUM_SKIP_WORKTREE The number of files in the index with skip-worktree bit set.
# Non-negative integer.
# VCS_STATUS_NUM_ASSUME_UNCHANGED The number of files in the index with assume-unchanged bit set.
# Non-negative integer.
#
# The point of reporting -1 via VCS_STATUS_HAS_* is to allow the command to skip scanning files in
# large repos. See -m flag of gitstatus_start.
#
# gitstatus_query returns an error if gitstatus_start hasn't been called in the same shell or
# the call had failed.
#
# !!!!! WARNING: CONCURRENT CALLS WITH THE SAME NAME ARE NOT ALLOWED !!!!!
#
# It's illegal to call gitstatus_query if the last asynchronous call with the same NAME hasn't
# completed yet. If you need to issue concurrent requests, use different NAME arguments.
