</p>
<p>This command looks at your workspace, decides which files have
changed, and saves the changes to your database. It works by loading
the revision named in <a href="Storage-and-workflow.html#g_t_005fMTN_002frevision">_MTN/revision</a>, locating the base manifest
for your workspace, applying any pathname changes described, and then
comparing the updated base manifest to the files it finds in your
workspace, to determine which files have been edited.
</p>
<p>For each edited file, a delta is copied into the database. Then the
newly constructed manifest is recorded (as a delta) and finally the
new revision. Once all these objects are recorded in your database,
<code>commit</code> updates <samp>_MTN/revision</samp> to indicate that the base
revision is now the newly created revision, and that there are no
pathname changes to apply.
</p>
<p>Specifying pathnames to <code>commit</code> restricts the set of changes
that are visible and results in only a partial commit of the workspace.
Changes to files not included in the specified set of pathnames will be
ignored and will remain in the workspace until they are included in a
future commit. With a partial commit, only the relevant entries in
<samp>_MTN/revision</samp> will be removed and other entries will remain for
future commits.
</p>
<p>From within a subdirectory of the workspace the <code>commit</code> command
will, by default, include <em>all changes</em> in the workspace.
Specifying only the pathname "." will restrict <code>commit</code> to files
changed within the current subdirectory of the workspace.
</p>
<p>The <samp>--message</samp> and <samp>--message-file</samp> options are
mutually exclusive. Both provide a <var>logmsg</var> describing the
commit. <samp>--message-file</samp> specifies the name of the file
containing the log message, while <samp>--message</samp> provides it
directly.
</p>
<p>Multiple <samp>--message</samp> options may be provided on the command line.
The log message will be formed by concatenating the <samp>--message</samp>
options provided, with each one starting at the beginning of a new line.
</p>
<p>If neither <samp>--message-file</samp> nor <samp>--message</samp> are given,
the commit message defaults to the contents of <samp>_MTN/log</samp>, after
processing by the Lua hook <a href="User-Defaults.html#edit_005fcomment">edit_comment</a>. <samp>_MTN/log</samp> can be
edited by the user during their daily work to record the changes made
to the workspace.
</p>
<p>The default definition of <code>edit_comment</code> invokes the user’s
editor (specified by the environment variables <code>VISUAL</code> and
<code>EDITOR</code>, or <code>editor, vi</code>, or <code>notepad</code> on Windows).
</p>
<p><code>commit</code> formats the input to <code>edit_comment</code> as follows:
</p>
<div class="smallexample">
<pre class="smallexample"><contents of _MTN/log>
*** REMOVE THIS LINE TO CANCEL THE COMMIT ***
-- Enter a description of this change above --
-- Edit fields below to modify certificate values --
Branch: <from _MTN/options or option>
Author: <from key or option>
Date: <from system clock>
-- Modifications below this line are ignored --
Changes against parent <from _MTN/revision>
<list of changes>
</pre></div>
<p>When the user quits the editor, the text is processed as follows:
</p>
<ul>
<li> The final <var>logmsg</var> is all text up to the line “*** REMOVE THIS LINE
...” (the <em>cancel</em> line).
</li><li> If the <var>logmsg</var> is empty, the commit is aborted.
</li><li> If the cancel line is deleted or modified, the edited <var>logmsg</var> is
saved in <samp>_MTN/log</samp>, and the commit is aborted.
</li><li> The next two lines (instructions) are confirmed to be present. If not,
the commit is aborted, and the entire file is saved in <samp>_MTN/commit</samp>,
so the user may recover.
</li><li> The <em>Branch</em>, <em>Author</em>, and <em>Date</em> fields are parsed, and
the new values used for the commit. If the parsing fails, the commit
is aborted, and the entire file is saved in <samp>_MTN/commit</samp>,
so the user may recover.
<p>The date is formatted with the spec provided by <samp>--date-format</samp>
or Lua hook <code><a href="User-Defaults.html#get_005fdate_005fformat_005fspec">get_date_format_spec</a></code>. When the date field is
parsed, the same spec is used. Therefore this spec must be supported
by the operating system function for parsing dates; if not, the
monotone internal format of “yyyy-mm-ddThh:mm:ss” is used for both
formatting and parsing.
</p>
</li><li> The rest of the text is ignored.
</li></ul>
<p>If the commit is successful, the <samp>_MTN/log</samp> file is cleared of
all content making it ready for another edit/commit cycle.
</p>
<p>As a special case, if <samp>--message-file=_MTN/log</samp> is specified,
the contents of <samp>_MTN/log</samp> will be used without first invoking
<code>edit_comment</code>.
</p>
<p>If a <samp>--branch</samp> option is specified, the <code>commit</code> command
commits to this branch (creating it if necessary). The branch becomes
the new default branch of the workspace.
</p>
<p>The <code>commit</code> command also synthesizes a number of
certificates, which it attaches to the new manifest version and copies
into your database:
</p><ul>
<li> An <code>author</code> cert, indicating the person responsible for the
changes leading to the new revision. Normally this defaults to your
signing key or the return value of the <a href="User-Defaults.html#get_005fauthor">get_author</a> hook; you may
override this by passing the <samp>--author</samp> option to commit, or by
editing the <em>Author</em> field in your editor. This is useful when
committing a patch on behalf of someone else, or when importing “by
hand” from another version control system.
</li><li> A <code>branch</code> cert, indicating the branch the committed revision
belongs to.
</li><li> A <code>date</code> cert, indicating when the new revision was created.
Normally this defaults to the current date and time; you may override
this by passing the <samp>--date</samp> option to commit, or by editing
the <em>Date</em> field in your editor. This is useful when importing
“by hand” from another version control system.
</li><li> A <code>changelog</code> cert, containing the <var>logmsg</var>.
</li></ul>

<a name="index-mtn-rm"></a>
</dt>
<dd><p><code>rm</code> is an alias for <code>drop</code>.
</p>
<p>This command places “drop” entries for the paths specified in
<var>pathname...</var> in <a href="Storage-and-workflow.html#g_t_005fMTN_002frevision">_MTN/revision</a> and deletes the file from the
workspace. This will be part of the next <code>commit</code>. If any of
<var>pathname...</var> is a directory, and <samp>--recursive</samp> is not
given, and the directory contains any versioned files, the command
will fail. If <samp>--recursive</samp> is given, the versioned files will be
dropped. If the directory contains unversioned files, it will be
dropped from the revision, but not deleted from the disk.
</p>
<p>If <samp>--missing</samp> is given, <code>drop</code> will add drop entries
for any versioned paths in <var>pathname...</var> for which you have
already removed the files from the filesystem.
</p>
<p>This command also removes any attributes on <var>pathname</var>; see
<a href="File-Attributes.html#File-Attributes">File Attributes</a> for more details.
</p>
<p>If <samp>--bookkeep-only</samp> is given, or if a file is different from
the version in the base revision, <code>drop</code> will drop remove
<var>pathname...</var> from the revision at commit time, but <em>not</em>
remove the file from the workspace.
</p>
<p>See the <code>undrop</code> command for undoing a <code>drop</code> before commit.

</dt>
<dd><p>Most users will never need this command. It is primarily useful in
certain tricky cases where one wishes to combine several projects
into one, or split one project into several. See also <code>merge_into_dir</code>.
</p>
<p>Its effect is to rename the directory whose name is currently
<var>new_root</var> to become the root directory of the versioned tree, and
to at the same time rename the directory that is currently the root of
the versioned tree to have the name <var>put_old</var>. Conceptually, it
is equivalent to executing the following commands in the root of the
workspace:
</p>
<div class="smallexample">
<pre class="smallexample">$ mtn rename . <var>new_root</var>/<var>put_old</var>
$ mtn rename <var>new_root</var> .
</pre></div>
<p>Except, of course, that these <code>rename</code> commands are illegal,
because after the first command the tree has no root at all, and there
is a directory loop. This illegality is the only reason for
<code>pivot_root</code>’s existence; internally, the result is treated
exactly like two renames, including with respect to merges and
updates.
</p>
<p>The use of <samp>--bookkeep-only</samp> with this command is not
recommended. It causes the changes to be made in monotone’s
records, but not in the filesystem itself.
</p>
<p>When running <code>pivot_root</code>, it is sometimes possible for
<a href="Workspace-Collisions.html#Workspace-Collisions">Workspace Collisions</a> to occur.

<p>This command takes changes made at any point in history, and attempts to
edit your current workspace to include those changes. The end result is
identical to running <code>mtn diff <samp>-r</samp> <var>from</var>
<samp>-r</samp> <var>to</var> | patch <samp>-p0</samp></code>, except that this command
uses monotone’s merger, and thus intelligently handles renames,
conflicts, and so on.
</p>
<p>If only one revision is given, applies the changes made in <var>to</var> as
compared with <var>to</var>’s parent. If two revisions are given, applies
the changes made to get from <var>from</var> to <var>to</var>.
</p>
<p>Note that this is not a true cherrypick operation. A true cherrypick,
as that word is used in version control theory, involves applying some
changes out of context, and then recording the identity between the
original changes and the newly applied changes for the use of later
merges. This command does the first part, not the second. As far as
monotone is concerned, the changes made by <code>mtn pluck</code> are
exactly like those made in an editor; the command is simply a
convenient way to make certain edits quickly. In practice, this is
rarely a problem. <code>mtn pluck</code> should almost always be used
between branches that will never be merged — for instance,
backporting fixes from a development branch to a stable branch.
</p>
<p>When you use <code>pluck</code> you are going behind monotone’s back, and
reducing its ability to help you keep track of what has happened in
your history. Never use <code>pluck</code> where a true merging command
like <code>merge</code>, <code>propagate</code>, or <code>explicit_merge</code>
will do. If you find yourself using <code>pluck</code> often, you should
consider carefully whether there is any way to change your workflow to
reduce your need for <code>pluck</code>ing.

<p>This command changes your workspace, so that changes you have made
since the last checkout or update are discarded. The command is
restricted the set of files or directories given as arguments. To
revert the entire workspace, use <code>revert</code> "." in the
top-level directory. Specifying "." in a subdirectory will restrict
<code>revert</code> to files changed within the current subdirectory.
</p>
<p>If <samp>--missing</samp> is given it reverts any versioned files in

<dd><p>This command changes your workspace to have the a different revision as
the base revision.
</p>
<p><code>update</code> performs 3 separate stages. If any of these stages
fails, the update aborts, doing nothing. The first two stages select
the target revision; they are skipped if <samp>--revision</samp> is given
- that revision is the target.
</p>
<p>In the first stage, if <samp>--branch</samp> is not given, the workspace
branch is used. If <samp>--branch</samp> is given, the branch becomes the
new default branch of the workspace (even if you also specify an
explicit <samp>--revision</samp> argument).
</p>
<ul>
<li> Examine the ancestry graph of revisions on the branch in your
database, and (subject to trust evaluation; see <a href="Trust-Evaluation-Hooks.html#Trust-Evaluation-Hooks">Trust Evaluation Hooks</a>) select the set of all descendants of your workspace’s base
revision. Call this set the “candidates” of the update.
</li><li> Remove any candidates which lack acceptable testresult certificates;
see <a href="Trust-Evaluation-Hooks.html#accept_005ftestresult_005fchange">accept_testresult_change</a> (defaults to all candidates). From
the remaining candidates, select the deepest child by ancestry and
call it the “target” of the update.
</li><li> Merge the target of the update with the workspace, in memory, and
if the merge is successful, write the result over top of the workspace.
</li></ul>
<p>The effect is always to take whatever changes you have made in the
workspace, and to “transpose” them onto a new revision, using
monotone’s 3-way merge algorithm to achieve good results. Note that
with the explicit <samp>--revision</samp> argument, it is possible to update
“backwards” or “sideways” in history — for example, reverting to
an earlier revision, or if your branch has two heads, updating to the
other. In all cases, the end result will be whatever revision you
specified, with your local changes (and only your local changes)
applied.
