(["dates"], _("Date Formats"),
_(r'''
Some commands allow the user to specify a date:
backout, commit, import, tag: Specify the commit date.
log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
"Wed Dec 6 13:18:29 2006" (local timezone assumed)
"Dec 6 13:18 -0600" (year assumed, time offset provided)
"Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000)
"Dec 6" (midnight)
"13:18" (today assumed)
"3:39" (3:39AM assumed)
"3:39pm" (15:39)
"2006-12-06 13:18:29" (ISO 8601 format)
"2006-12-6 13:18"
"2006-12-6"
"12-6"
"12/6"
"12/6/6" (Dec 6 2006)
Lastly, there is Mercurial's internal format:
"1165432709 0" (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. unixtime is
the number of seconds since the epoch (1970-01-01 00:00 UTC). offset
is the offset of the local timezone, in seconds west of UTC (negative
if the timezone is east of UTC).
The log command also accepts date ranges:
"<{date}" - on or before a given date
">{date}" - on or after a given date
"{date} to {date}" - a date range, inclusive
"-{days}" - within a given number of days of today

(["patterns"], _("File Name Patterns"),

Mercurial accepts several notations for identifying one or more
files at a time.
By default, Mercurial treats filenames as shell-style extended
glob patterns.
Alternate pattern notations must be specified explicitly.
To use a plain path name without any pattern matching, start a
name with "path:". These path names must match completely, from
the root of the current repository.
To use an extended glob, start a name with "glob:". Globs are
rooted at the current directory; a glob such as "*.c" will match
files ending in ".c" in the current directory only.
The supported glob syntax extensions are "**" to match any string
across path separators, and "{a,b}" to mean "a or b".
To use a Perl/Python regular expression, start a name with "re:".
Regexp pattern matching is anchored at the root of the repository.
Plain examples:
path:foo/bar a name bar in a directory named foo in the root of
the repository
path:path:name a file or directory named "path:name"
Glob examples:
glob:*.c any name ending in ".c" in the current directory
*.c any name ending in ".c" in the current directory
**.c any name ending in ".c" in the current directory, or
any subdirectory
foo/*.c any name ending in ".c" in the directory foo
foo/**.c any name ending in ".c" in the directory foo, or any
subdirectory
Regexp examples:
re:.*\.c$ any name ending in ".c", anywhere in the repository

_(r'''
HG::
Path to the 'hg' executable, automatically passed when running hooks,
extensions or external tools. If unset or empty, an executable named
'hg' (with com/exe/bat/cmd extension on Windows) is searched.
HGEDITOR::
This is the name of the editor to use when committing. See EDITOR.
(deprecated, use .hgrc)
HGENCODING::
This overrides the default locale setting detected by Mercurial.
This setting is used to convert data including usernames,
changeset descriptions, tag names, and branches. This setting can
be overridden with the --encoding command-line option.
HGENCODINGMODE::
This sets Mercurial's behavior for handling unknown characters
while transcoding user inputs. The default is "strict", which
causes Mercurial to abort if it can't translate a character. Other
settings include "replace", which replaces unknown characters, and
"ignore", which drops them. This setting can be overridden with
the --encodingmode command-line option.
HGMERGE::
An executable to use for resolving merge conflicts. The program
will be executed with three arguments: local file, remote file,
ancestor file.
(deprecated, use .hgrc)
HGRCPATH::
A list of files or directories to search for hgrc files. Item
separator is ":" on Unix, ";" on Windows. If HGRCPATH is not set,
platform default search path is used. If empty, only .hg/hgrc of
current repository is read.
For each element in path, if a directory, all entries in directory
ending with ".rc" are added to path. Else, element itself is
added to path.
HGUSER::
This is the string used for the author of a commit.
(deprecated, use .hgrc)
EMAIL::
If HGUSER is not set, this will be used as the author for a commit.
LOGNAME::
If neither HGUSER nor EMAIL is set, LOGNAME will be used (with
'@hostname' appended) as the author value for a commit.
VISUAL::
This is the name of the editor to use when committing. See EDITOR.
EDITOR::
Sometimes Mercurial needs to open a text file in an editor
for a user to modify, for example when writing commit messages.
The editor it uses is determined by looking at the environment
variables HGEDITOR, VISUAL and EDITOR, in that order. The first
non-empty one is chosen. If all of them are empty, the editor
defaults to 'vi'.
PYTHONPATH::
This is used by Python to find imported modules and may need to be set
appropriately if Mercurial is not installed system-wide.

(['revs', 'revisions'], _('Specifying Single Revisions'),
_(r'''
Mercurial accepts several notations for identifying individual
revisions.
A plain integer is treated as a revision number. Negative
integers are treated as offsets from the tip, with -1 denoting the
tip.
A 40-digit hexadecimal string is treated as a unique revision
identifier.
A hexadecimal string less than 40 characters long is treated as a
unique revision identifier, and referred to as a short-form
identifier. A short-form identifier is only valid if it is the
prefix of one full-length identifier.
Any other string is treated as a tag name, which is a symbolic
name associated with a revision identifier. Tag names may not
contain the ":" character.
The reserved name "tip" is a special tag that always identifies
the most recent revision.
The reserved name "null" indicates the null revision. This is the
revision of an empty repository, and the parent of revision 0.
The reserved name "." indicates the working directory parent. If
no working directory is checked out, it is equivalent to null.
If an uncommitted merge is in progress, "." is the revision of
the first parent.
''')),
(['mrevs', 'multirevs'], _('Specifying Multiple Revisions'),
_(r'''
When Mercurial accepts more than one revision, they may be
specified individually, or provided as a continuous range,
separated by the ":" character.
The syntax of range notation is [BEGIN]:[END], where BEGIN and END
are revision identifiers. Both BEGIN and END are optional. If
BEGIN is not specified, it defaults to revision number 0. If END
is not specified, it defaults to the tip. The range ":" thus
means "all revisions".
If BEGIN is greater than END, revisions are treated in reverse
order.
A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 4:2 gives 4, 3, and 2.
''')),
(['diffs'], _('Diff Formats'),
_(r'''
Mercurial's default format for showing changes between two versions
of a file is compatible with the unified format of GNU diff, which
can be used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the
following information:
- executable status
- copy or rename information
- changes in binary files
- creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS
which addresses these limitations. The git diff format is not
produced by default because there are very few tools which
understand this format.
This means that when generating diffs from a Mercurial repository
(e.g. with "hg export"), you should be careful about things like
file copies and renames or other things mentioned above, because
when applying a standard diff to a different repository, this extra
information is lost. Mercurial's internal operations (like push and
pull) are not affected by this, because they use an internal binary
format for communicating changes.
To make Mercurial produce the git extended diff format, use the
--git option available for many commands, or set 'git = True' in the
[diff] section of your hgrc. You do not need to set this option when
importing diffs in this format or using them in the mq extension.

(['templating'], _('Template Usage'),
_(r'''
Mercurial allows you to customize output of commands through
templates. You can either pass in a template from the command line,
via the --template option, or select an existing template-style (--style).
You can customize output for any "log-like" command: log, outgoing,
incoming, tip, parents, heads and glog are all template-enabled.
Three styles are packaged with Mercurial: default (the style used
when no explicit preference is passed), compact and changelog. Usage:
$ hg log -r1 --style changelog
A template is a piece of text, with markup to invoke variable expansion:
$ hg log -r1 --template "{node}\n"
b56ce7b07c52de7d5fd79fb89701ea538af65746
Strings in curly braces are called keywords. The availability of
keywords depends on the exact context of the templater. These keywords
are usually available for templating a log-like command:
- author: String. The unmodified author of the changeset.
- branches: String. The name of the branch on which the changeset
was committed. Will be empty if the branch name was default.
- date: Date information. The date when the changeset was committed.
- desc: String. The text of the changeset description.
- files: List of strings. All files modified, added, or removed by
this changeset.
- file_adds: List of strings. Files added by this changeset.
- file_mods: List of strings. Files modified by this changeset.
- file_dels: List of strings. Files removed by this changeset.
- node: String. The changeset identification hash, as a 40-character
hexadecimal string.
- parents: List of strings. The parents of the changeset.
- rev: Integer. The repository-local changeset revision number.
- tags: List of strings. Any tags associated with the changeset.
The "date" keyword does not produce human-readable output. If you
want to use a date in your output, you can use a filter to process it.
Filters are functions which return a string based on the input variable.
You can also use a chain of filters to get the wanted output:
$ hg tip --template "{date|isodate}\n"
2008-08-21 18:22 +0000
List of filters:
- addbreaks: Any text. Add an XHTML "<br />" tag before the end of
every line except the last.
- age: Date. Returns a human-readable age for the given date.
- basename: Any text. Treats the text as a path, and returns the
basename. For example, "foo/bar/baz" becomes "baz".
- date: Date. Returns a date in a Unix date command format, including
the timezone: "Mon Sep 04 15:13:13 2006 0700".
- domain: Any text. Finds the first string that looks like an email
address, and extracts just the domain component.
- email: Any text. Extracts the first string that looks like an email
address.
- escape: Any text. Replaces the special XML/XHTML characters "&",
"<" and ">" with XML entities.
- fill68: Any text. Wraps the text to fit in 68 columns.
- fill76: Any text. Wraps the text to fit in 76 columns.
- firstline: Any text. Returns the first line of text.
- hgdate: Date. Returns the date as a pair of numbers:
"1157407993 25200" (Unix timestamp, timezone offset).
- isodate: Date. Returns the date in ISO 8601 format.
- obfuscate: Any text. Returns the input text rendered as a sequence
of XML entities.
- person: Any text. Returns the text before an email address.
- rfc822date: Date. Returns a date using the same format used
in email headers.
- short: Changeset hash. Returns the short form of a changeset hash,
i.e. a 12-byte hexadecimal string.
- shortdate: Date. Returns a date like "2006-09-04".
- strip: Any text. Strips all leading and trailing whitespace.
- tabindent: Any text. Returns the text, with every line except the
first starting with a tab character.
- urlescape: Any text. Escapes all "special" characters. For example,
"foo bar" becomes "foo%20bar".
- user: Any text. Returns the user portion of an email address.
