NAME

tla - arch command line client tool

SYNOPSIS

tla command [ command_options ]
tla command [-h|--help|-H]
tla [-h|--help|-H|-V|--version]

DESCRIPTION

tla is an implementation of arch .

arch is a version control system, which allows you to keep old versions of files and
directories (usually source code), keep a log of who, when, and why changes occurred,
etc., like SVN, CVS, or RCS.

arch has a number of advantages compared to competing systems. Among these are:

Works on Whole Trees
arch keeps track of whole trees -- not just individual files. For example, if you change
many files in a tree, arch can record all of those changes as a group rather than
file-by-file; if you rename files or reorganize a tree, arch can record those tree
arrangements along with your changes to file contents.

Changeset Oriented
arch doesn´t simply "snapshot" your project trees. Instead, arch associates each revision
with a particular changeset: a description of exactly what has changed. arch provides
changeset oriented commands to help you review changesets, merge trees by applying
changesets, examine the history of a tree by asking what changesets have been applied to
it, and so forth.

Fully Distributed
arch doesn´t rely on a central repository. For example, there is no need to give write
access to a project´s archive to all significant contributors. Instead, each contributor
can have their own archive for their work. arch seamlessly operates across archive
boundaries.

HELP

tla help
provide help with arch

Usage: tla help [options]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-b, --basic Display basic commands only
-V, --version Display a release identifier string
and exit.

This command prints a list of the available commands.

To see just a list of the options to a particular command, use:

tla $cmd -h

(where $cmd is the name of the command). For additional explanation about a given
command, use:

tla $cmd -H

USER COMMANDS

tla my-id
print or change your id

Usage: tla my-id [options] [id]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-e, --errname specify program name for errors
-u, --uid print only the UID portion of the ID

With no argument print your arch id.

With an argument, record ID-STRING as your id in ~/.arch-params/=id

Your id is recorded in various archives and log messages as you use arch. It must consist
entirely of printable characters and fit on one line. By convention, it should have the
form of an email address, as in this example:

Jane Hacker <[email protected]>

The portion of an id string between < and > is called your uid. arch sometimes uses your
uid as a fragment when generating unique file names.

The option -u (--uid) causes only the uid part of your id string to be printed.

tla my-default-archive
print or change your default archive

Usage: tla my-default-archive [options] [archive]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-A, --archive Override `my-default-archive´
-e, --errname specify program name for errors
-d, --delete unspecify your default archive
-s, --silent suppress reassuring messages

With no argument, and without -d, print the name of your default archive.

With an argument, record ARCHIVE as your default archive in
~/.arch-params/=default-archive

With the option -d (--delete) and no argument, ensure that you do not have a default
archive set in ~/.arch-params.

Your default archive is determined this way:

If the option -A (--archive) is given and not empty, that archive is the default (which
makes this script useful for processing a -A argument that was passed to another script).

If -A is not given, but ~/.arch-params/=default-archive exists and is not empty, that is
your default archive.

Otherwise, your default archive is the name of the local archive rooted at the argument to
-R (--root) or specified in the environment variable ARCHROOT.

If no default archive can be found by any of these means, the program exits with status 1,
printing an error message unless the -s (--silent) option is given.

tla register-archive
change an archive location registration

Usage: tla register-archive [options] [archive] location

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-f, --force overwrite existing location
--present-ok return 0 even if archive exists
-d, --delete delete archive registration

Record the location of ARCHIVE.

With -d, remove the registration of a previously registered archive. When accompanied by
-f, override permissions on the registration file and don´t complain if the archive is not
registered.

A LOCATION should be either a directory name or a distant URL.

When registering a new archive, if no ARCHIVE´s name is passed on the command line, then
the archive´s name will be read automatically from the archive´s meta data.

Archive locations are stored in ~/.arch-params/=locations.

You must register the location of a remote archive before you access it. It is not
strictly necessary to register the locations of local archives (you can always specify
their location using command line arguments and/or environment variables), but registering
local archive locations is recommend (for simplicity).

tla whereis-archive
print an archive location registration

Usage: tla whereis-archive [options] archive

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.

Print the registered location of an archive.

Usually the archive must have been previously registered with "tla register-archive".

As a special exception, the the archive is not registered, but is the name of the archive
rooted at the location given with the option -R (--root) or in the environment variable
ARCHROOT then print that root directory.

tla archives
report registered archives and their locations

Usage: tla archives [options] [search regular expression]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-n, --names print archive names only
-R, --exclude-remote Exclude MIRROR and SOURCE archives.

Print a list of registered archives and their locations

If [search regex] is given then only archives with names that match [search regex] will be
shown

PROJECT TREE COMMANDS

initialize a new project tree

Usage: tla init-tree [options] [[archive]/version]

-h, --help Display a help message and exit.

and exit.
-A, --archive Override `my-default-archive´
-d, --dir DIR cd to DIR first
--nested initialize a nested project tree.

Initialize DIR as a new project tree.

An empty patch-log for VERSION will be created, and VERSION will be made the default
location for check-ins.

tla tree-root
find and print the root of a project tree

Usage: tla tree-root [options] [dir]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
--accurate error for mid-txn trees
-s, --silent exit status only

Find and print the root of the project tree that contains DIR (or the current directory).
The option --accurate checks for three possibilities:

1) The project tree was the subject of a commit that
was killed before the log entry was added to the
tree´s patch log. It is unknown whether or not
the commit took place in the archive. The {arch}
directory contains the log file as "++mid-commit".

2) The project tree was the subject of a killed commit, but
it is certain the commit took place. The log file
is stored as "++commit-definite".

3) The project tree patch log is fully up-to-date (as far as
arch knows).

In case 1, exit with an error and error message.

In case 2, install the log file before printing the tree root and exiting normally.

In case 3, print the tree root and exit normally.

tla tree-version
print the default version for a project tree

Usage: tla tree-version [options] [dir]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.

Usage: tla tree-id [options] [dir]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.

Print the patchset identifier that represents the current tree-> I.e.
[email protected]/demo--1.0--patch-4. Defaults to the tree the current directory is in.

tla tree-revision
Print the tree identifier for a project tree

Usage: tla tree-revision [options] [dir]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.

Print the patchset identifier that represents the current tree-> I.e.
[email protected]/demo--1.0--patch-4. Defaults to the tree the current directory is in.

tla set-tree-version
set the default version for a project tree

Usage: tla set-tree-version [options] [archive]/version

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-A, --archive Override `my-default-archive´
-d, --dir DIR cd to DIR first

This operation sets the default version on which to check-in the source tree DIR (default:
the current directory) during a commit.

You can specify the archive for this version as an ordinary command line argument
(ARCHIVE/VERSION) or via -R, -A and the environment as usual (try "tla my-default-archive
--help").

tla undo
undo and save changes in a project tree

-n, --no-output do not save the changeset
-N, --forward pass the --forward option to `patch´
-q, --quiet no progress reports while computing changeset
--unescaped show filenames in unescaped form

Compute a patch set describing the changes from REVISION to the project tree containing
DIR. Save the patch in PATCH-DIR (which must not already exist) and apply the patch in
reverse to the project tree containing DIR.

The effect is to remove local changes in the DIR project tree but save them in a
convenient form.

If REVISION is not specified, the latest ancestor of the default version of project tree
is used.

If REVISION is specified as a VERSION, the latest ancestor of the project tree in that
VERSION is used.

If DIR is not specified, "." is assumed.

If PATCH-DIR is not specified, a temporary file-name of the matching ,,undo-* is used.

If --no-output is specified, the patch set is not saved.

See also "tla redo -H" and "tla changes -H".

-k, --keep do not delete the patch
-q, --quiet no progress reports while computing changeset
-d, --dir DIR Operate on project tree in DIR (default `.´)
--unescaped show filenames in unescaped form

Apply CHANGESET to the project tree and then delete CHANGESET.

If CHANGESET is not specified, the highest numbered ,,undo-N directory in the project tree
root is used.

If --keep is given, the changeset directory is not deleted.

PROJECT TREE INVENTORY COMMANDS

tla inventory
inventory a source tree

Usage: tla inventory [options] [--] [dir]*

--tagline permit tagline file ids
--names use name-based file ids
--unescaped show filenames in unescaped form

With no arguments, print a human-readable inventory report.

With category options (--source etc) limit the report to just those files. With no other
options, the report includes all sections and files.

The options -d, -f, and -b cancel each other.

If a directory is precious, junk, or unrecognized, only the directory name itself is
printed -- its contents are not searched.

Each command option implies the corresponding category option (e.g. "--source-command"
implies "--source"). The exit status of the command is ignored.

tla tree-lint
(alias for lint)

Usage: tla tree-lint [options] [dir]

-h, --help Display a help message and exit.

By default, this command sets, prints or deletes a "strong default" -- a default explicit
id which overrides implicit ids.

With --weak, set (or print) a weak default id which is overridden by explicit ids.

The --dont-care option sets (or with -d, clears) a flag for that directory that causes
unidged files not to be reported as such in "tla tree-lint" reports.

ARCHIVE TRANSACTION COMMANDS

tla make-archive
create a new archive directory

Usage: tla make-archive [options] [name] location

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-m, --mirror MASTER create mirror of specified archive
-M, --mirror-from MASTER-SOURCE create pull-based mirror of specified archive
-l, --listing Keep .listing files up-to-date in this archive.
-t, --tla Create a tla format archive.
-b, --baz Create a baz format archive (the default).
-s, --signed GPG sign the contents of this archive.

NAME is the global name for the archive. It must be an email address with a fully
qualified domain name, optionally followed by "--" and a string of letters, digits,
periods and dashes.

With --mirror, label the new archive as a mirror of MASTER. Ordinary commits can not be
made to a mirror archive, however the command "tla archive-mirror" can write to a mirror.

Two special forms of this command are available:

tla make-archive --mirror MASTER LOCATION

is equivalent to:

tla make-archive --mirror MASTER MASTER-MIRROR LOCATION

and thus "tla archive-mirror MASTER" will push changes from MASTER to the newly created
mirror.

tla make-archive --mirror-from MASTER-SOURCE LOCATION

is equivalent to:

tla make-archive --mirror MASTER-SOURCE MASTER LOCATION

and thus "tla archive-mirror MASTER" will pull changes from MASTER-SOURCE to the newly
created mirror.

The first of these two special forms is especially handy when creating a remote mirror in
which to publish a local repository.

The second special form is handy when creating a local mirror of a remote archive, locally
bound to the remote archive´s name.

The --tla option creates a tla format archive, the default is to create a Bazaar archive.

tla archive-setup
create new categories, branches and versions

Usage: tla archive-setup [options] [version ...]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-A, --archive Override `my-default-archive´
-f, --file FILE read the list of desired versions from FILE
-b, --branches make base-0 tags
-c, --cache archive cache when creating base-0 tags

Given a list of categories, branches, and versions, ensure that these exist in the
appropriate archive.

For example, starting with an empty archive,:

% tla archive-setup proja--devo--1.0 projb

creates a category, branch, and version for project A, and a category for project B

When the --file option is used, the list of items to create is read from a file (use "-"
to indicate standard input).

With the --file option, the option --branches may be provided. In this case, the input
should have two items per line: a target version (to create), and a source version to
build a tag from. For example, given an input file containg:

proja--devo--1.0 [email protected]/proja--devo--1.0

with --branches, archive-setup creates a proja version in your default archive, and adds a
base-0 revision to that project which is a tag of the latest revision in [email protected]´s
archive. (This can make it quite easy to set-up a new archive which contains branches
from existing archives, for example.)

If --branches is used, the --cache option may also be used. It causes each new base-0
revision to be archive-cached (see "tla cacherev -H")

tla make-category
create a new archive category

Usage: tla make-category [options] category

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.

-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.

Create BRANCH as a branch in the indicated archive.

The category containing the branch must already exist.

tla make-version
create a new archive version

Usage: tla make-version [options] version

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string

--no-setup Do not use `archive-setup´ even if necessary.
--unescaped show filenames in unescaped form

Archive a from-scratch base revision of the project tree containing DIR (or the current
directory). Use this command to create the first revision of a new project.

If --log-message is specified without --summary, then TEXT is used both as the summary and
the first line of the log body.

--fix create a versionfix revision
--out-of-date-ok commit even if out of date
--file-list FILE commit only changes to files listed in FILE
--write-revision REVISION_FILE_SPEC write the new tree id to REVISION_FILE_SPEC
before committing
--unescaped show filenames in unescaped form

Archive a revision of the project tree containing DIR (or the current directory)

If there are any automated ChangeLog files, update them before computing the patch set.

If --log-message is specified without --summary, then TEXT is used both as the summary and
the first line of the log body.

Extract REVISION from an archive, creating the new project tree DIR. If DIR is not
specified, store the working copy in a subdirectory of the current directory, giving it
the name of the revision. CAUTION: when using the links option be sure to use
copy-on-write on your editor or the revision library will be corrupted. Either way, the
project tree must not already exist.

-f, --force overwrite an exiting config (with --output)
-s, --snap Show current patch levels of subtree packages.
--unescaped show filenames in unescaped form

Parse and print the indicate config file from a project tree

A config file contains blank lines, comment lines starting with "#", and config
specification lines. The config file called $NAME is stored in a project tree as
./configs/$NAME or as ./$NAME.

A config specification line contains a relative path within a project tree, and a
specification of the project or revision to store in that location.

For example, the line:

./src/arch [email protected]/arch--devo--1.0

means that, when building the configuration, the latest revision of arch--devo--1.0 should
be created within the tree as ./src/arch.

The project specification can be a branch name, version name or the name of a specific
revision.

The option --snap says to examine the project tree to find out which revisions of
configured project are printed, and generate a new config specification that references
those specific revisions. For example, the output for the line shown above might be:

./src/arch [email protected]/arch--devo--1.0--patch-21

The option --output causes the output from this command to be recorded as a new
configuration file (or to replace an existing file if --force is provided).

-N, --forward pass the --forward option to `patch´
--dest DEST Instead of modifying the project tree in-place,
make a copy of it to DEST and apply the result to that
--unescaped show filenames in unescaped form

Update a project tree by getting the latest revision of VERSION (or the default version of
the project tree) and then applying a patch set of the differences between the project
tree and the highest revision with which it is up-to-date.

If the merge involves conflicts, a warning message is printed, and the new project tree
will contain ".rej" files.

tla replay
apply revision changesets to a project tree

Usage: tla replay [options] [version/revision...]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.

--skip-present skip patches that contain 1 or more patch logs already in this tree
--unescaped show filenames in unescaped form

The result is formed by applying patches in the latest revision of VERSION (or the default
version of the project tree), stopping after the first patch that causes conflicts. If
multiple VERSIONs are specified, they are applied in turn.

If one or more specific REVISIONs (including patch-levels) is specified instead, only
those patch sets, and no others, will be applied.

With the --list option, read a list of patches to apply from FILE (- for standard input).
Complete revision names should be listed, one per line. replay will stop at the first
patch in the list that causes a merge conflict, leaving behind files with names of the
form:

,,replay.conflicts-in -- the name of the patch that caused conflicts

,,replay.remaining -- the list of patches not yet applied

tla star-merge
merge mutually merged branches

Usage: tla star-merge [options] [FROM]

-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-A, --archive Override tree archive
-c, --changes OUTPUT Generate but don´t apply the changeset.
-r, --reference VERSION Set reference version (default: project tree version)
-N, --forward pass the --forward option to `patch´
-t, --three-way Perform a 3-way (diff3-style) merge.
-d, --dir DIR Operate on project tree in DIR (default `.´)
--unescaped show filenames in unescaped form

Merge changes from FROM into the project tree, considering common ancestry from the
project tree reference version, REFERENCE (which defaults to the tree version of the
project tree). If FROM is not given, it defaults to the tree revision.

The purpose of this command is to merge changes between development lines which may have
merged in both directions. It uses merge history to attempt to minimize the spurious
conflicts that can arise from `mutual merging´.

FROM indicates a revision (it may be specified as a version name, indicating the latest
revision in that version).

TREE is the project tree into which the merge will occur.

Star-merge works by computing the most recent ANCESTOR revision of REFERENCE and FROM and
then applying the changeset:

delta (ANCESTOR, FROM)

to TREE.

The "most recent ancestor" is defined as follows:

MAYBE_ANCESTOR_1 is defined as the highest patch level of FROM in REFERENCE for which both
TREE and FROM have a patch log. In other words, it is the latest REFERENCE revision of
FROM´s version already merged into TREE.

MAYBE_ANCESTOR_2 is defined as the highest patch level in REFERENCE for which both FROM
and REFERENCE have a patch log. In other words, it is the latest revision of REFERENCE
already merged into FROM.

MAYBE_ANCESTOR_2, if it is not "nil", was merged into FROM at some revision of FROM´s
version, which we can call LAST_MERGE_INTO_FROM.

If both MAYBE_ANCESTOR_1 or MAYBE_ANCESTOR_2 are nil, star-merge can do nothing.

If just one of MAYBE_ANCESTOR_1 is MAYBE_ANCESTOR_2 is not nil, then that non-nil value is
ANCESTOR.

If both MAYBE_ANCESTOR_1 and MAYBE_ANCESTOR_2 are not nil, then LAST_MERGE_INTO_FROM and
MAYBE_ANCESTOR_1 are compared (both are revisions in FROM´s version). If MAYBE_ANCESTOR_1
is the later revision, then MAYBE_ANCESTOR_1 is ANCESTOR, otherwise, MAYBE_ANCESTOR_2 is
ANCESTOR.

tla apply-delta
compute a changeset between any two trees or revisions and apply it to a project tree

Usage: tla apply-delta [options] FROM(REVISION|DIR) TO(REVISION|DIR)

-d, --dir DIR Operate on project tree in DIR (default `.´)
--dest DEST Instead of modifying the project tree in-place,
make a copy of it to DEST and apply the result to that
--unescaped show filenames in unescaped form

A delta between A and B (both of which may be either a full revision or a project tree) is
computed, and then applied to the project tree.

Exit Status Codes:

0 No conflict during patch
1 Conflicts occurred during patch
3 Internal Error

tla missing
print patches missing from a project tree

-c, --creator display the creator of each missing patch
-D, --date display the date of each missing patch
-f, --full print full revision names
--merges print a merge list for each missing patch
--skip-present skip patches that contain 1 or more patch logs already in this tree

Print a list of patches missing in the project tree containing DIR (or the current
directory) for VERSION (or the default version. of the project tree).

The flag --merges means, for each patch, to print the list of patches included in the
patch in two columns. For example:

PATCH-A PATCH-A
PATCH-A PATCH-B
PATCH-A PATCH-C

means that PATCH-A includes the changes from PATCH-B and PATCH-C. (Every patch includes at
least itself.)

With -x, if there are missing patches, the command exits with status 1, otherwise with
status 0.

With -q, produce no output.

WARNING: At this time, some error conditions *also* exit with error status 1, however, in
situations where the caller is not concerned with errors, the exit status is still useful.

--dest DEST Instead of modifying the project tree in-place,
make a copy of it to DEST and apply the result to that
--unescaped show filenames in unescaped form

VERSION--base-0 must be a continuation (e.g. tag). The command replays the changeset for
VERSION--base-0 in the project tree, which has the effect of adding the log for the branch
(making the tag an ancestor of the resulting tree).

tla sync-tree
unify a project tree´s patch-log with a given revision

Usage: tla sync-tree [options] revision

-h, --help Display a help message and exit.

--dest DEST Instead of modifying the project tree in-place,
make a copy of it to DEST and apply the result to that
--unescaped show filenames in unescaped form

The new project tree is formed by getting the REVISION and adding all patch-log entries
from REVISION. No actual merging is performed -- only the patch-log is changed.

--unescaped show filenames in unescaped form

Given (REVISION|TREE)-A and (REVISION|TREE)-B, tla will build a changeset that comprises
the changes between REVISION-A and REVISION-B

Example:
tla delta tla--devo--1.1--patch-6 tla--devo--1.1--patch-8 ,,changes

Will pull patch-6 and patch-8 from tla--devo--1.1 and compute
a changeset, which will be saved in a newly created ,,changes

ENVIRONMENT

EDITOR If $EDITOR is set, use its value as the path of the text editor arch is to run when
asking the user for text input. If unset, log messages must be given on the command
line using the `-L´ parameter or in the file created by `tla make-log´.

HOME User´s home directory, where arch looks for .arch-cache/ and .arch-params/ .

http_proxy HTTP_PROXY
If $http_proxy or $HTTP_PROXY is set, arch used its value as the URL of the proxy
to use for WebDAV accesses. $http_proxy has higher priority than $HTTP_PROXY. If
unset, no proxy is used.

TMPDIR If $TMPDIR is set, arch creates temporary files in the given directory. Otherwise,
it uses `/tmp´.
