Workbench
=========

.. module:: workbench.dialog
	:synopsis: Primary TortoiseHg application

The Workbench is the primary TortoiseHg application.  It allows you
to browse your local repositories, make commits, perform searches,
synchronize with other repositories, and perform various maintenance
tasks.  Nearly every Mercurial feature is accessible from the Workbench.

	:alt: Workbench

	Workbench dialog.

Workbench Main Widgets are:

	:guilabel:`Revision History View`
		A tabbed widget to view multiple repositories at once. The different
		columns show general information about each changeset in the graphlog.
		You can configure the columns to show from the menu via
		:menuselection:`View --> Choose Log Columns...`, and there you can reorder
		the columns too. This is the main or central widget of the 	Workbench
		application.

	:guilabel:`Repository Registry`
		This widget, by default shown on the left, allows to manage multiple
		repositories from the Workbench. You can show/hide it via
		:menuselection:`View --> Show Repo Registry` or with the corresponding button
		in the Dock Toolbar. It's also a dockable widget.
		The :menuselection:`View --> Show Paths` menu option allows to not only view
		the names of the repositories but also their path in a second column.
	
	:guilabel:`Output Log`
		This dockable widget, which can be shown/hidden with
		:menuselection:`View --> Show Output Log`, gives the user information about
		the Mercurial commands that were executed during the current session.
		You can also use it as a commandline by typing Mercurial commands at its
		prompt 	directly. It shows any error messages when appropriate. Content
		is wiped when the Workbench is closed.

	:guilabel:`Task Tabs`
		The lower right part of the Workbench is occupied by a stack of widget
		where you can perform various frequent tasks. It is a tabbed widget.
		See further for more detail about each one.

Workbench Menus
---------------

The Workbench has a menu bar for accessing tool functions and for
launching other tools.

	:alt: Sync Toolbar
	
	Sync toolbar

Synchronize your repository with other repositories.

	:guilabel:`Incoming`
		Download incoming changesets from the remote repository, store then in
		a temporary bundle file, then enter bundle preview mode with the
		incoming changes applied.  Incoming changesets will be shown as normal,
		while others will be shown grayed in the revision graph.
		The buttons :guilabel:`Accept` and :guilabel:`Reject` are then
		shown at the top of the revision graph.
	:guilabel:`Pull`
		Pull incoming changesets from the remote repository, then apply
		after-pull effect (update, fetch, or rebase).
	:guilabel:`Outgoing`
		Determine outgoing changesets that would be pushed to the
		remote repository.  Outgoing changesets will be shown as normal, while
		others will be shown grayed in the revision graph.
	:guilabel:`Push`
		Push outgoing changesets to the remote repository.

Task Toolbar
------------

.. figure:: figures/task-toolbar.png
	:alt: Task Toolbar
	
	Task toolbar

Work with the various task tabs.

	:guilabel:`Revision Details`
		Shows information about the current revision : files added, removed,
		renamed, or modified, file contents, changeset info.
		See _`Revision Details` for more detail.

..

There is some relation between the revision or patch selected in the graph pane,
and the task tabs.

* Clicking on the Working Directory automatically switches to the Commit task tab.

* Clicking on any revision other than the Working Directory switches to the
  Revision Details task tab.

You can overrule this standard behaviour by doing an :kbd:`ALT-Click` for making
your selection. This preserves the current task tab, no matter what revision or
patch you select.  Cursor selection movements also do not switch task tabs.


Filter Toolbar
--------------

.. figure:: figures/filter-toolbar.png
	:alt: Filter Toolbar

	Filter features for the Workbench.

The filter bar allows one to quickly filter the changesets panel. It is based
on the Revision Sets feature of Mercurial.
See `hg.1.html#revsets <http://www.selenic.com/mercurial/hg.1.html#revsets>`_ 
for details on how to specify revision sets.
The toolbar can be toggled with :kbd:`Ctrl-S`. Parts from left to right:

	:guilabel:`Clear`
		Clears the search lineedit.  Essentially disables all filters.
	:guilabel:`Filter entry`
		Here you can type a filtering condition. The widget is a combobox,
		holding a history of previous filtering conditions.
	:guilabel:`Trigger`
		Applies the condition set by the filter.
	:guilabel:`Open`
		Opens the RevSet dialog. There you can select and/or enter your
		condition in a combined way via point-and-click and by typing.
	:guilabel:`Delete`
		Deletes the selected query.
	:guilabel:`Toggle filter`
		Applies the filter condition by sowing changesets that don't conform
		to it in a color suggesting insensitiveness, so the selected ones
		stand out more.
	:guilabel:`Branch options`
		A few options for showing branches.
		See :menuselection:`Repo Settings --> Workbench --> Dead Branches` for
		a method to prune names from this combo box.
	:guilabel:`Branches combo`
		A combo box with the list of named branches in your repository.
	:guilabel:`Custom Filter Combo`
		Finally there is a combo box that selects among the various
		filter types that can be manually specified.

If the repository tab is previewing incoming changesets, a pair of
buttons are prepended to the start of the filter bar:

	:guilabel:`Accept`
		Accept (pull) the changesets from the previewed bundle.  This
		button is only visible when previewing a changeset bundle.
		The after-pull effect is respected after pulling from a bundle.

	:guilabel:`Reject`
		Reject the changesets from the previewed bundle and exit preview
		mode.  This button is only visible when previewing a changeset
		bundle.

The Workbench will attempt to lookup the entered search phrase in the
repository to see if it matches a tag, bookmark, branch name, changeset
hash, or revision number.  If no changeset match is found, the Workbench
checks if the search phrase has any parentheses.  If no parentheses are
found, the Workbench assumes the search is a keyword and performs a
:command:`keyword()` revision set search. If parentheses are found, the
Workbench assumes the search phrase is a revision set specification and
attempts to resolve the set.

If you need to perform a keyword search that includes parentheses, use
:command:`keyword("PHRASE(FOO)")`.

Revision Graph Details
----------------------

The graph column shows the child-parent relationships between revisions
in your repository history.  This column auto-sizes for as many lines of
ancestry that are required to visualize the revisions you have loaded.
The column has an initial hard-limit width to prevent some degenerative
cases from breaking the viewer, but can be resized after refreshes.

Performance Implications
------------------------

There are some Workbench features that could have performance implications in
large repositories.

	:menuselection:`View --> Choose Log columns...` 
		Enabling the :guilabel:`Changes` column can be expensive to calculate
		on repositories with large working copies, causing both refreshes and
		scrolling to be slow.

	:menuselection:`View --> Load all`
		Normally, when the user scrolls through the history, chunks of changesets
		are read as you scroll. This menu choice allows you to have the Workbench
		read all the changesets from the repository, probably allowing smoother
		moving through the history.

Revision Context Menus
----------------------

Right-clicking on revisions in the graph pane brings up a different context menu
when one, two, or more revisions are selected. Context menus can also differ
according to the type of revision(s) (working dir, regular revision,
(un)applied mq patch). Here we give a list of all existing context menu entries.

Right-clicking on a selection of revisions in the (top) graph pane will bring up
the revision context menu.

	:guilabel:`Delete unversioned`
		Deletes unversioned files from disk.

Message Parsing
---------------

The changeset display pane will detect and underline changeset hashes,
HTTP(s) URLs, and bug report identifiers inside changeset messages.
These underlined phrases are clickable links.

Every word-boundary delimited string of 12 or 40 characters from the
range [0-9a-f] is considered a changeset link. Clicking on it in the
repository explorer will jump to the given changeset if possible.

HTTP and HTTPS URLs are similarly turned into clickable links which are
opened in your default web browser.

Issue tracker links are enabled when configured in the tortoisehg
section of your configuration files.  Since only a single issue tracker
can be configured at a time, it is typically configured in the
repository's :file:`.hg/hgrc` file.  There are two keys: issue.regex and
issue.link. The first defines the regex to match when picking up issue
numbers, while the second defines the command to run when an issue
number is recognized.

You may include groups in issue.regex, and corresponding {n} tokens in
issue.link (where n is a non-negative integer). {0} refers to the entire
string matched by issue.regex, while {1} refers to the first group and
so on. If no {n} tokens are found in issue.link, the entire matched
string is appended instead.

Examples::

	BitBucket:
	issue.regex = #(\d+)\b
	issue.link = https://bitbucket.org/<your project and repo>/issue/{1}/

	Mercurial:
	issue.regex = \bissue(\d+)\b
	issue.link = http://bz.selenic.com/show_bug.cgi?id={1}

Output Log Console
------------------

The console built into the Workbench Output Log dock widget can run
Mercurial (hg) commands, TortoiseHg (thg) commands, a couple special
commands, and limited shell commands.  Commands are always executed in
the root of the current repository.  The prompt is updated to keep you
aware of the context.

If the command line begins with 'hg', the Mercurial command is run in
TortoiseHg's execution environment; meaning output is sent to the log
widget and input requests are handled by dialog windows.

If the command line begins with 'thg', the requested command is run in a
new window but in the same process.  For instance 'thg ci' will open a
new commit tool window for the current repository.

It the command is 'clear' (or 'cls'), the output log contents are
erased.

If the command is 'exit', the output log window is closed.

Otherwise, the command line is forwarded to your platform's default
command shell with a limited execution context.  There is no stdin while
stdout and stderr are piped to the output log.

Keyboard navigation
-------------------

:kbd:`Ctrl-P`
	Zoom to the working directory parent revision
:kbd:`Ctrl-D`
	Display visual diffs for selected changeset or file
:kbd:`Ctrl-S`
	Toggle revision set / filter toolbar

See also `KeySequences <https://bitbucket.org/tortoisehg/thg/wiki/KeySequences>`_
on the wiki pages.

Configurables
-------------

The Workbench has a few configurable options that can be set in
the TortoiseHg Settings dialog on the Workbench tab.

	:guilabel:`Author coloring`
		If true, each author's changeset will be given a unique color
	:guilabel:`Long Summary`
		Concatenate commit message lines until 80 chars are reached
	:guilabel:`Graph batch limit`
		Number of revisions to read in each batch load
	:guilabel:`Dead Branches`
		Comma separated list of branch names that should be ignored
		when building a list of branch names for a repository.
	:guilabel:`Branch Colors`
		Space separated list of branch names and colors on the
		form branch:#XXXXXX. Spaces and colons in the branch name must be
		escaped using a backslash (\\). Likewise some other characters
		can be escaped in this way, e.g. \\u0040 will be decoded to the
		@ character, and \\n to a linefeed.
	:guilabel:`Hide Tags`
		Space separated list of tags that will not be shown.  Useful
		example: Specify "qbase qparent qtip" to hide the standard tags
		inserted by the Mercurial Queues Extension.

The exact colors given to particular users can be configured by adding
lines like these to your :file:`Mercurial.ini` file: ::

	[tortoisehg]
	authorcolor.USERNAME = color

The Workbench also respects the following settings on the
TortoiseHg tab:

	:guilabel:`Tab Width`
		Number of spaces to expand tabs in diffs
	:guilabel:`Max Diff Size`
		Maximum size of file to be diffed


From command line
-----------------

The Workbench can be started from command line ::

	thg log [OPTIONS] [FILE]

	aliases: history, explorer, workbench

	workbench application

	use "thg -v help log" to show global options

.. vim: noet ts=4
