tests: guess lexer by filename for recent pygments
Recent pygments guess AntlrJavaLexer for the isolatin text, converted to ascii
by util.tolocal, which yields class="err". Guess lexer by extension instead.

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: "<{datetime}" - at or before a given date/time ">{datetime}" - on or after a given date/time "{datetime} to {datetime}" - a date range, inclusive "-{days}" - within a given number of days of today ''')), (["patterns"], _("File Name Patterns"), _(r''' 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 it with "path:". These path names must completely match starting at the current repository root. To use an extended glob, start a name with "glob:". Globs are rooted at the current directory; a glob such as "*.c" will only match files in the current directory ending with ".c". 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 any subdirectory of the current directory including itself. foo/*.c any name ending in ".c" in the directory foo foo/**.c any name ending in ".c" in any subdirectory of foo including itself. Regexp examples: re:.*\.c$ any name ending in ".c", anywhere in the repository ''')), (['environment', 'env'], _('Environment Variables'), _(r''' HG:: Path to the 'hg' executable, automatically passed when running hooks, extensions or external tools. If unset or empty, this is the hg executable's name if it's frozen, or an executable named 'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is searched. HGEDITOR:: This is the name of the editor to run 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 input. The default is "strict", which causes Mercurial to abort if it can't map 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 the .hg/hgrc from the current repository is read. For each element in HGRCPATH: * if it's a directory, all files ending with .rc are added * otherwise, the file itself will be added HGUSER:: This is the string used as the author of a commit. If not set, available values will be considered in this order: * HGUSER (deprecated) * hgrc files from the HGRCPATH * EMAIL * interactive prompt * LOGNAME (with '@hostname' appended) (deprecated, use .hgrc) EMAIL:: May be used as the author of a commit; see HGUSER. LOGNAME:: May be used as the author of a commit; see HGUSER. 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 this Mercurial is not installed system-wide. ''')), (['revs', 'revisions'], _('Specifying Single Revisions'), _(r''' Mercurial supports several ways to specify individual revisions. A plain integer is treated as a revision number. Negative integers are treated as topological offsets from the tip, with -1 denoting the tip. As such, negative numbers are only useful if you've memorized your local tree numbers and want to save typing a single digit. This editor suggests copy and paste. 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 exactly 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 topologically 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 9:6 gives 9, 8, 7, and 6. ''')), (['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 and other permission bits - 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 a few widespread tools still do not 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. 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. - diffstat: String. Statistics of changes with the following format: "modified files: +added/-removed lines" - 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 desired 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 date/time difference between the given date/time and the current date/time. - basename: Any text. Treats the text as a path, and returns the last component of the path after splitting by the path separator (ignoring trailing seprators). For example, "foo/bar/baz" becomes "baz" and "foo/bar//" becomes "bar". - date: Date. Returns a date in a Unix date 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. Example: 'User <user@example.com>' becomes 'example.com'. - email: Any text. Extracts the first string that looks like an email address. Example: 'User <user@example.com>' becomes 'user@example.com'. - 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 "2006-09-18". - 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. ''')), (['urls'], _('Url Paths'), _(r''' Valid URLs are of the form: local/filesystem/path (or file://local/filesystem/path) http://[user[:pass]@]host[:port]/[path] https://[user[:pass]@]host[:port]/[path] ssh://[user[:pass]@]host[:port]/[path] Paths in the local filesystem can either point to Mercurial repositories or to bundle files (as created by 'hg bundle' or 'hg incoming --bundle'). An optional identifier after # indicates a particular branch, tag, or changeset to use from the remote repository. Some features, such as pushing to http:// and https:// URLs are only possible if the feature is explicitly enabled on the remote Mercurial server. Some notes about using SSH with Mercurial: - SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path or specified with as remotecmd. - path is relative to the remote user's home directory by default. Use an extra slash at the start of a path to specify an absolute path: ssh://example.com//tmp/repository - Mercurial doesn't use its own compression via SSH; the right thing to do is to configure it in your ~/.ssh/config, e.g.: Host *.mylocalnetwork.example.com Compression no Host * Compression yes Alternatively specify "ssh -C" as your ssh command in your hgrc or with the --ssh command line option. These urls can all be stored in your hgrc with path aliases under the [paths] section like so: [paths] alias1 = URL1 alias2 = URL2 ... You can then use the alias for any command that uses a url (for example 'hg pull alias1' would pull from the 'alias1' path). Two path aliases are special because they are used as defaults when you do not provide the url to a command: default: When you create a repository with hg clone, the clone command saves the location of the source repository as the new repository's 'default' path. This is then used when you omit path from push- and pull-like commands (including in and out). default-push: The push command will look for a path named 'default-push', and prefer it over 'default' if both are defined.
