Usage: gitstatusd [OPTION]...
Print machine-readable status of the git repos for directores in stdin.

OPTIONS
  -l, --lock-fd=NUM [default=-1]
   If non-negative, check whether the specified file descriptor is locked when
   not receiving any requests for one second; exit if it isn't locked.

  -p, --parent-pid=NUM [default=-1]
   If non-negative, send signal 0 to the specified PID when not receiving any
   requests for one second; exit if signal sending fails.

  -t, --num-threads=NUM [default=1]
   Use this many threads to scan git workdir for unstaged and untracked files.
   Empirically, setting this parameter to twice the number of virtual CPU yields
   maximum performance.

  -v, --log-level=STR [default=INFO]
   Don't write entires to log whose log level is below this. Log levels in
   increasing order: DEBUG, INFO, WARN, ERROR, FATAL.

  -r, --repo-ttl-seconds=NUM [default=3600]
   Close git repositories that haven't been used for this long. This is meant to
   release resources such as memory and file descriptors. The next request for a
   repo that's been closed is much slower than for a repo that hasn't been.
   Negative value means infinity.

  -s, --max-num-staged=NUM [default=1]
   Report at most this many staged changes; negative value means infinity.

  -u, --max-num-unstaged=NUM [default=1]
   Report at most this many unstaged changes; negative value means infinity.

  -d, --max-num-untracked=NUM [default=1]
   Report at most this many untracked files; negative value means infinity.

  -m, --dirty-max-index-size=NUM [default=-1]
   If a repo has more files in its index than this, override --max-num-unstaged
   and --max-num-untracked (but not --max-num-staged) with zeros; negative value
   means infinity.

  -e, --recurse-untracked-dirs
   Count files within untracked directories like `git status --untracked-files`.

  -U, --ignore-status-show-untracked-files
   Unless this option is specified, report zero untracked files for repositories
   with status.showUntrackedFiles = false.

  -W, --ignore-bash-show-untracked-files
   Unless this option is specified, report zero untracked files for repositories
   with bash.showUntrackedFiles = false.

  -D, --ignore-bash-show-dirty-state
   Unless this option is specified, report zero staged, unstaged and conflicted
   changes for repositories with bash.showDirtyState = false.

  -V, --version
   Print gitstatusd version and exit.

  -G, --version-glob=STR [default=*]
   Immediately exit with code 11 if gitstatusd version (see --version) doesn't
   does not match the specified pattern. Matching is done with fnmatch(3)
   without flags.

  -h, --help
  Display this help and exit.

INPUT

  Requests are read from stdin, separated by ascii 30 (record separator). Each
  request is made of the following fields, in the specified order, separated by
  ascii 31 (unit separator):

    1. Request ID. Any string. Can be empty.
    2. Path to the directory for which git stats are being requested.
       If the first character is ':', it is removed and the remaning path
       is treated as GIT_DIR.
    3. (Optional) '1' to disable computation of anything that requires reading
       git index; '0' for the default behavior of computing everything.

OUTPUT

  For every request read from stdin there is response written to stdout.
  Responses are separated by ascii 30 (record separator). Each response is made
  of the following fields, in the specified order, separated by ascii 31
  (unit separator):

     1. Request id. The same as the first field in the request.
     2. 0 if the directory isn't a git repo, 1 otherwise. If 0, all the
        following fields are missing.
     3. Absolute path to the git repository workdir.
     4. Commit hash that HEAD is pointing to. 40 hex digits.
     5. Local branch name or empty if not on a branch.
     6. Upstream branch name. Can be empty.
     7. The remote name, e.g. "upstream" or "origin".
     8. Remote URL. Can be empty.
     9. Repository state, A.K.A. action. Can be empty.
    10. The number of files in the index.
    11. The number of staged changes.
    12. The number of unstaged changes.
    13. The number of conflicted changes.
    14. The number of untracked files.
    15. Number of commits the current branch is ahead of upstream.
    16. Number of commits the current branch is behind upstream.
    17. The number of stashes.
    18. The last tag (in lexicographical order) that points to the same
        commit as HEAD.
    19. The number of unstaged deleted files.
    20. The number of staged new files.
    21. The number of staged deleted files.
    22. The push remote name, e.g. "upstream" or "origin".
    23. Push remote URL. Can be empty.
    24. Number of commits the current branch is ahead of push remote.
    25. Number of commits the current branch is behind push remote.
    26. Number of files in the index with skip-worktree bit set.
    27. Number of files in the index with assume-unchanged bit set.

Note: Renamed files are reported as deleted plus new.

EXAMPLE

  Send a single request and print response (zsh syntax):

    local req_id=id
    local dir=$PWD
    echo -nE $req_id$'\x1f'$dir$'\x1e' | ./gitstatusd | {
      local resp
      IFS=$'\x1f' read -rd $'\x1e' -A resp && print -lr -- "${(@qq)resp}"
    }

  Output:
    'id'
    '1'
    '/home/romka/gitstatus'
    'bf46bf03dbab7108801b53f8a720caee8464c9c3'
    'master'
    'master'
    'origin'
    'git@github.com:romkatv/gitstatus.git'
    ''
    '70'
    '1'
    '0'
    '0'
    '2'
    '0'
    '0'
    ''
    '0'
    '0'
    '0'
    ''
    ''
    '0'
    '0'
    '0'
    '0'

EXIT STATUS

  The command returns zero on success (when printing help or on EOF),
  non-zero on failure. In the latter case the output is unspecified.
