     1.4 +\chapter{Customising the output of Mercurial}
     1.5 +\label{chap:template}
     1.6 +
     1.7 +Mercurial provides a powerful mechanism to let you control how it
     1.8 +displays information.  The mechanism is based on templates.  You can
     1.9 +use templates to generate specific output for a single command, or to
    1.10 +customise the entire appearance of the built-in web interface.
    1.11 +
    1.12 +\section{Using precanned output styles}
    1.13 +\label{sec:style}
    1.14 +
    1.15 +Packaged with Mercurial are some output styles that you can use
    1.16 +immediately.  A style is simply a precanned template that someone
    1.17 +wrote and installed somewhere that Mercurial can find.
    1.18 +
    1.19 +Before we take a look at Mercurial's bundled styles, let's review its
    1.20 +normal output.
    1.21 +
    1.22 +\interaction{template.simple.normal}
    1.23 +
    1.24 +This is somewhat informative, but it takes up a lot of space---five
    1.25 +lines of output per changeset.  The \texttt{compact} style reduces
    1.26 +this to three lines, presented in a sparse manner.
    1.27 +
    1.28 +\interaction{template.simple.compact}
    1.29 +
    1.30 +The \texttt{changelog} style hints at the expressive power of
    1.31 +Mercurial's templating engine.  This style attempts to follow the GNU
    1.32 +Project's changelog guidelines\cite{web:changelog}.
    1.33 +
    1.34 +\interaction{template.simple.changelog}
    1.35 +
    1.36 +You will not be shocked to learn that Mercurial's default output style
    1.37 +is named \texttt{default}.
    1.38 +
    1.39 +\subsection{Setting a default style}
    1.40 +
    1.41 +You can modify the output style that Mercurial will use for every
    1.42 +command by editing your \hgrc\ file, naming the style you would
    1.43 +prefer to use.
    1.44 +
    1.45 +\begin{codesample2}
    1.46 +  [ui]
    1.47 +  style = compact
    1.48 +\end{codesample2}
    1.49 +
    1.50 +If you write a style of your own, you can use it by either providing
    1.51 +the path to your style file, or copying your style file into a
    1.52 +location where Mercurial can find it (typically the \texttt{templates}
    1.53 +subdirectory of your Mercurial install directory).
    1.54 +
    1.55 +\section{Commands that support styles and templates}
    1.56 +
    1.57 +All of Mercurial's ``\texttt{log}-like'' commands let you use styles
    1.58 +and templates: \hgcmd{incoming}, \hgcmd{log}, \hgcmd{outgoing}, and
    1.59 +\hgcmd{tip}.
    1.60 +
    1.61 +As I write this manual, these are so far the only commands that
    1.62 +support styles and templates.  Since these are the most important
    1.63 +commands that need customisable output, there has been little pressure
    1.64 +from the Mercurial user community to add style and template support to
    1.65 +other commands.
    1.66 +
    1.67 +\section{The basics of templating}
    1.68 +
    1.69 +At its simplest, a Mercurial template is a piece of text.  Some of the
    1.70 +text never changes, while other parts are \emph{expanded}, or replaced
    1.71 +with new text, when necessary.
    1.72 +
    1.73 +Before we continue, let's look again at a simple example of
    1.74 +Mercurial's normal output.
    1.75 +
    1.76 +\interaction{template.simple.normal}
    1.77 +
    1.78 +Now, let's run the same command, but using a template to change its
    1.79 +output.
    1.80 +
    1.81 +\interaction{template.simple.simplest}
    1.82 +
    1.83 +The example above illustrates the simplest possible template; it's
    1.84 +just a piece of static text, printed once for each changeset.  The
    1.85 +\hgopt{log}{--template} option to the \hgcmd{log} command tells
    1.86 +Mercurial to use the given text as the template when printing each
    1.87 +changeset.
    1.88 +
    1.89 +Notice that the template string above ends with the text
    1.90 +``\Verb+\n+''.  This is an \emph{escape sequence}, telling Mercurial
    1.91 +to print a newline at the end of each template item.  If you omit this
    1.92 +newline, Mercurial will run each piece of output together.  See
    1.93 +section~\ref{sec:template:escape} for more details of escape sequences.
    1.94 +
    1.95 +A template that prints a fixed string of text all the time isn't very
    1.96 +useful; let's try something a bit more complex.
    1.97 +
    1.98 +\interaction{template.simple.simplesub}
    1.99 +
   1.100 +As you can see, the string ``\Verb+{desc}+'' in the template has been
   1.101 +replaced in the output with the description of each changeset.  Every
   1.102 +time Mercurial finds text enclosed in curly braces (``\texttt{\{}''
   1.103 +and ``\texttt{\}}''), it will try to replace the braces and text with
   1.104 +the expansion of whatever is inside.  To print a literal curly brace,
   1.105 +you must escape it, as described in section~\ref{sec:template:escape}.
   1.106 +
   1.107 +\section{Common template keywords}
   1.108 +\label{sec:template:keyword}
   1.109 +
   1.110 +You can start writing simple templates immediately using the keywords
   1.111 +below.
   1.112 +
   1.113 +\begin{itemize}
   1.114 +\item[\tplkword{author}] String.  The unmodified author of the changeset.
   1.115 +\item[\tplkword{branches}] String.  The name of the branch on which
   1.116 +  the changeset was committed.  Will be empty if the branch name was
   1.117 +  \texttt{default}.
   1.118 +\item[\tplkword{date}] Date information.  The date when the changeset
   1.119 +  was committed.  This is \emph{not} human-readable; you must pass it
   1.120 +  through a filter that will render it appropriately.  See
   1.121 +  section~\ref{sec:template:filter} for more information on filters.
   1.122 +  The date is expressed as a pair of numbers.  The first number is a
   1.123 +  Unix UTC timestamp (seconds since January 1, 1970); the second is
   1.124 +  the offset of the committer's timezone from UTC, in seconds.
   1.125 +\item[\tplkword{desc}] String.  The text of the changeset description.
   1.126 +\item[\tplkword{files}] List of strings.  All files modified, added, or
   1.127 +  removed by this changeset.
   1.128 +\item[\tplkword{file\_adds}] List of strings.  Files added by this
   1.129 +  changeset.
   1.130 +\item[\tplkword{file\_dels}] List of strings.  Files removed by this
   1.131 +  changeset.
   1.132 +\item[\tplkword{node}] String.  The changeset identification hash, as a
   1.133 +  40-character hexadecimal string.
   1.134 +\item[\tplkword{parents}] List of strings.  The parents of the
   1.135 +  changeset.
   1.136 +\item[\tplkword{rev}] Integer.  The repository-local changeset revision
   1.137 +  number.
   1.138 +\item[\tplkword{tags}] List of strings.  Any tags associated with the
   1.139 +  changeset.
   1.140 +\end{itemize}
   1.141 +
   1.142 +A few simple experiments will show us what to expect when we use these
   1.143 +keywords; you can see the results in
   1.144 +figure~\ref{fig:template:keywords}.
   1.145 +
   1.146 +\begin{figure}
   1.147 +  \interaction{template.simple.keywords}
   1.148 +  \caption{Template keywords in use}
   1.149 +  \label{fig:template:keywords}
   1.150 +\end{figure}
   1.151 +
   1.152 +As we noted above, the date keyword does not produce human-readable
   1.153 +output, so we must treat it specially.  This involves using a
   1.154 +\emph{filter}, about which more in section~\ref{sec:template:filter}.
   1.155 +
   1.156 +\interaction{template.simple.datekeyword}
   1.157 +
   1.158 +\section{Escape sequences}
   1.159 +\label{sec:template:escape}
   1.160 +
   1.161 +Mercurial's templating engine recognises the most commonly used escape
   1.162 +sequences in strings.  When it sees a backslash (``\Verb+\+'')
   1.163 +character, it looks at the following character and substitutes the two
   1.164 +characters with a single replacement, as described below.
   1.165 +
   1.166 +\begin{itemize}
   1.167 +\item[\Verb+\textbackslash\textbackslash+] Backslash, ``\Verb+\+'',
   1.168 +  ASCII~134.
   1.169 +\item[\Verb+\textbackslash n+] Newline, ASCII~12.
   1.170 +\item[\Verb+\textbackslash r+] Carriage return, ASCII~15.
   1.171 +\item[\Verb+\textbackslash t+] Tab, ASCII~11.
   1.172 +\item[\Verb+\textbackslash v+] Vertical tab, ASCII~13.
   1.173 +\item[\Verb+\textbackslash \{+] Open curly brace, ``\Verb+{+'', ASCII~173.
   1.174 +\item[\Verb+\textbackslash \}+] Close curly brace, ``\Verb+}+'', ASCII~175.
   1.175 +\end{itemize}
   1.176 +
   1.177 +As indicated above, if you want the expansion of a template to contain
   1.178 +a literal ``\Verb+\+'', ``\Verb+{+'', or ``\Verb+{+'' character, you
   1.179 +must escape it.
   1.180 +
   1.181 +\section{Filtering keywords to change their results}
   1.182 +\label{sec:template:filter}
   1.183 +
   1.184 +Some of the results of template expansion are not immediately easy to
   1.185 +use.  Mercurial lets you specify an optional chain of \emph{filters}
   1.186 +to modify the result of expanding a keyword.  You have already seen a
   1.187 +common filter, \tplkwfilt{date}{isodate}, in action above, to make a
   1.188 +date readable.
   1.189 +
   1.190 +Below is a list of the most commonly used filters that Mercurial
   1.191 +supports.  While some filters can be applied to any text, others can
   1.192 +only be used in specific circumstances.  The name of each filter is
   1.193 +followed first by an indication of where it can be used, then a
   1.194 +description of its effect.
   1.195 +
   1.196 +\begin{itemize}
   1.197 +\item[\tplfilter{addbreaks}] Any text. Add an XHTML ``\Verb+<br/>+''
   1.198 +  tag before the end of every line except the last.  For example,
   1.199 +  ``\Verb+foo\nbar+'' becomes ``\Verb+foo<br/>\nbar+''.
   1.200 +\item[\tplkwfilt{date}{age}] \tplkword{date} keyword.  Render the
   1.201 +  age of the date, relative to the current time.  Yields a string like
   1.202 +  ``\Verb+10 minutes+''.
   1.203 +\item[\tplfilter{basename}] Any text, but most useful for the
   1.204 +  \tplkword{files} keyword and its relatives.  Treat the text as a
   1.205 +  path, and return the basename. For example, ``\Verb+foo/bar/baz+''
   1.206 +  becomes ``\Verb+baz+''.
   1.207 +\item[\tplkwfilt{date}{date}] \tplkword{date} keyword.  Render a date
   1.208 +  in a similar format to the Unix \tplkword{date} command, but with
   1.209 +  timezone included.  Yields a string like
   1.210 +  ``\Verb+Mon Sep 04 15:13:13 2006 -0700+''.
   1.211 +\item[\tplkwfilt{author}{domain}] Any text, but most useful for the
   1.212 +  \tplkword{author} keyword.  Finds the first string that looks like
   1.213 +  an email address, and extract just the domain component.  For
   1.214 +  example, ``\Verb+Bryan O'Sullivan <bos@serpentine.com>+'' becomes
   1.215 +  ``\Verb+serpentine.com+''.
   1.216 +\item[\tplkwfilt{author}{email}] Any text, but most useful for the
   1.217 +  \tplkword{author} keyword.  Extract the first string that looks like
   1.218 +  an email address.  For example,
   1.219 +  ``\Verb+Bryan O'Sullivan <bos@serpentine.com>+'' becomes
   1.220 +  ``\Verb+bos@serpentine.com+''.
   1.221 +\item[\tplfilter{escape}] Any text.  Replace the special XML/XHTML
   1.222 +  characters ``\Verb+&+'', ``\Verb+<+'' and ``\Verb+>+'' with
   1.223 +  XML entities.
   1.224 +\item[\tplfilter{fill68}] Any text.  Wrap the text to fit in 68
   1.225 +  columns.  This is useful before you pass text through the
   1.226 +  \tplfilter{tabindent} filter, and still want it to fit in an
   1.227 +  80-column fixed-font window.
   1.228 +\item[\tplfilter{fill76}] Any text.  Wrap the text to fit in 76
   1.229 +  columns.
   1.230 +\item[\tplfilter{firstline}] Any text.  Yield the first line of text,
   1.231 +  without any trailing newlines.
   1.232 +\item[\tplkwfilt{date}{hgdate}] \tplkword{date} keyword.  Render the
   1.233 +  date as a pair of readable numbers.  Yields a string like
   1.234 +  ``\Verb+1157407993 25200+''.
   1.235 +\item[\tplkwfilt{date}{isodate}] \tplkword{date} keyword.  Render the
   1.236 +  date as a text string in ISO~8601 format.  Yields a string like
   1.237 +  ``\Verb+2006-09-04 15:13:13 -0700+''.
   1.238 +\item[\tplfilter{obfuscate}] Any text, but most useful for the
   1.239 +  \tplkword{author} keyword.  Yield the input text rendered as a
   1.240 +  sequence of XML entities.  This helps to defeat some particularly
   1.241 +  stupid screen-scraping email harvesting spambots.
   1.242 +\item[\tplkwfilt{author}{person}] Any text, but most useful for the
   1.243 +  \tplkword{author} keyword.  Yield the text before an email address.
   1.244 +  For example, ``\Verb+Bryan O'Sullivan <bos@serpentine.com>+''
   1.245 +  becomes ``\Verb+Bryan O'Sullivan+''.
   1.246 +\item[\tplkwfilt{date}{rfc822date}] \tplkword{date} keyword.  Render a
   1.247 +  date using the same format used in email headers.  Yields a string
   1.248 +  like ``\Verb+Mon, 04 Sep 2006 15:13:13 -0700+''.
   1.249 +\item[\tplkwfilt{node}{short}] Changeset hash.  Yield the short form
   1.250 +  of a changeset hash, i.e.~a 12-byte hexadecimal string.
   1.251 +\item[\tplkwfilt{date}{shortdate}] \tplkword{date} keyword.  Render
   1.252 +  the year, month, and day of the date.  Yields a string like
   1.253 +  ``\Verb+2006-09-04+''.
   1.254 +\item[\tplfilter{strip}] Any text.  Strip all leading and trailing
   1.255 +  whitespace from the string.
   1.256 +\item[\tplfilter{tabindent}] Any text.  Yield the text, with every line
   1.257 +  except the first starting with a tab character.
   1.258 +\item[\tplfilter{urlescape}] Any text.  Escape all characters that are
   1.259 +  considered ``special'' by URL parsers.  For example, \Verb+foo bar+
   1.260 +  becomes \Verb+foo%20bar+.
   1.261 +\item[\tplkwfilt{author}{user}] Any text, but most useful for the
   1.262 +  \tplkword{author} keyword.  Return the ``user'' portion of an email
   1.263 +  address.  For example,
   1.264 +  ``\Verb+Bryan O'Sullivan <bos@serpentine.com>+'' becomes
   1.265 +  ``\Verb+bos+''.
   1.266 +\end{itemize}
   1.267 +
   1.268 +\begin{figure}
   1.269 +  \interaction{template.simple.manyfilters}
   1.270 +  \caption{Template filters in action}
   1.271 +  \label{fig:template:filters}
   1.272 +\end{figure}
   1.273 +
   1.274 +\begin{note}
   1.275 +  If you try to apply a filter to a piece of data that it cannot
   1.276 +  process, Mercurial will fail and print a Python exception.  For
   1.277 +  example, trying to run the output of the \tplkword{desc} keyword
   1.278 +  into the \tplkwfilt{date}{isodate} filter is not a good idea.
   1.279 +\end{note}
   1.280 +
   1.281 +\subsection{Combining filters}
   1.282 +
   1.283 +It is easy to combine filters to yield output in the form you would
   1.284 +like.  The following chain of filters tidies up a description, then
   1.285 +makes sure that it fits cleanly into 68 columns, then indents it by a
   1.286 +further 8~characters (at least on Unix-like systems, where a tab is
   1.287 +conventionally 8~characters wide).
   1.288 +
   1.289 +\interaction{template.simple.combine}
   1.290 +
   1.291 +Note the use of ``\Verb+\t+'' (a tab character) in the template to
   1.292 +force the first line to be indented; this is necessary since
   1.293 +\tplkword{tabindent} indents all lines \emph{except} the first.
   1.294 +
   1.295 +Keep in mind that the order of filters in a chain is significant.  The
   1.296 +first filter is applied to the result of the keyword; the second to
   1.297 +the result of the first filter; and so on.  For example, using
   1.298 +\Verb+fill68|tabindent+ gives very different results from
   1.299 +\Verb+tabindent|fill68+.
   1.300 +
   1.301 +
   1.302 +\section{From templates to styles}
   1.303 +
   1.304 +A command line template provides a quick and simple way to format some
   1.305 +output.  Templates can become verbose, though, and it's useful to be
   1.306 +able to give a template a name.  A style file is a template with a
   1.307 +name, stored in a file.
   1.308 +
   1.309 +More than that, using a style file unlocks the power of Mercurial's
   1.310 +templating engine in ways that are not possible using the command line
   1.311 +\hgopt{log}{--template} option.
   1.312 +
   1.313 +\subsection{The simplest of style files}
   1.314 +
   1.315 +Our simple style file contains just one line:
   1.316 +
   1.317 +\interaction{template.simple.rev}
   1.318 +
   1.319 +This tells Mercurial, ``if you're printing a changeset, use the text
   1.320 +on the right as the template''.
   1.321 +
   1.322 +\subsection{Style file syntax}
   1.323 +
   1.324 +The syntax rules for a style file are simple.
   1.325 +
   1.326 +\begin{itemize}
   1.327 +\item The file is processed one line at a time.
   1.328 +
   1.329 +\item Leading and trailing white space are ignored.
   1.330 +
   1.331 +\item Empty lines are skipped.
   1.332 +
   1.333 +\item If a line starts with either of the characters ``\texttt{\#}'' or
   1.334 +  ``\texttt{;}'', the entire line is treated as a comment, and skipped
   1.335 +  as if empty.
   1.336 +
   1.337 +\item A line starts with a keyword.  This must start with an
   1.338 +  alphabetic character or underscore, and can subsequently contain any
   1.339 +  alphanumeric character or underscore.  (In regexp notation, a
   1.340 +  keyword must match \Verb+[A-Za-z_][A-Za-z0-9_]*+.)
   1.341 +
   1.342 +\item The next element must be an ``\texttt{=}'' character, which can
   1.343 +  be preceded or followed by an arbitrary amount of white space.
   1.344 +
   1.345 +\item If the rest of the line starts and ends with matching quote
   1.346 +  characters (either single or double quote), it is treated as a
   1.347 +  template body.
   1.348 +
   1.349 +\item If the rest of the line \emph{does not} start with a quote
   1.350 +  character, it is treated as the name of a file; the contents of this
   1.351 +  file will be read and used as a template body.
   1.352 +\end{itemize}
   1.353 +
   1.354 +\section{Style files by example}
   1.355 +
   1.356 +To illustrate how to write a style file, we will construct a few by
   1.357 +example.  Rather than provide a complete style file and walk through
   1.358 +it, we'll mirror the usual process of developing a style file by
   1.359 +starting with something very simple, and walking through a series of
   1.360 +successively more complete examples.
   1.361 +
   1.362 +\subsection{Identifying mistakes in style files}
   1.363 +
   1.364 +If Mercurial encounters a problem in a style file you are working on,
   1.365 +it prints a terse error message that, once you figure out what it
   1.366 +means, is actually quite useful.
   1.367 +
   1.368 +\interaction{template.svnstyle.syntax.input}
   1.369 +
   1.370 +Notice that \filename{broken.style} attempts to define a
   1.371 +\texttt{changeset} keyword, but forgets to give any content for it.
   1.372 +When instructed to use this style file, Mercurial promptly complains.
   1.373 +
   1.374 +\interaction{template.svnstyle.syntax.error}
   1.375 +
   1.376 +This error message looks intimidating, but it is not too hard to
   1.377 +follow.
   1.378 +
   1.379 +\begin{itemize}
   1.380 +\item The first component is simply Mercurial's way of saying ``I am
   1.381 +  giving up''.
   1.382 +  \begin{codesample4}
   1.383 +    \textbf{abort:} broken.style:1: parse error
   1.384 +  \end{codesample4}
   1.385 +
   1.386 +\item Next comes the name of the style file that contains the error.
   1.387 +  \begin{codesample4}
   1.388 +    abort: \textbf{broken.style}:1: parse error
   1.389 +  \end{codesample4}
   1.390 +
   1.391 +\item Following the file name is the line number where the error was
   1.392 +  encountered.
   1.393 +  \begin{codesample4}
   1.394 +    abort: broken.style:\textbf{1}: parse error
   1.395 +  \end{codesample4}
   1.396 +
   1.397 +\item Finally, a description of what went wrong.
   1.398 +  \begin{codesample4}
   1.399 +    abort: broken.style:1: \textbf{parse error}
   1.400 +  \end{codesample4}
   1.401 +  The description of the problem is not always clear (as in this
   1.402 +  case), but even when it is cryptic, it is almost always trivial to
   1.403 +  visually inspect the offending line in the style file and see what
   1.404 +  is wrong.
   1.405 +\end{itemize}
   1.406 +
   1.407 +\subsection{Uniquely identifying a repository}
   1.408 +
   1.409 +If you would like to be able to identify a Mercurial repository
   1.410 +``fairly uniquely'' using a short string as an identifier, you can
   1.411 +use the first revision in the repository.
   1.412 +\interaction{template.svnstyle.id} 
   1.413 +This is not guaranteed to be unique, but it is nevertheless useful in
   1.414 +many cases.
   1.415 +\begin{itemize}
   1.416 +\item It will not work in a completely empty repository, because such
   1.417 +  a repository does not have a revision~zero.
   1.418 +\item Neither will it work in the (extremely rare) case where a
   1.419 +  repository is a merge of two or more formerly independent
   1.420 +  repositories, and you still have those repositories around.
   1.421 +\end{itemize}
   1.422 +Here are some uses to which you could put this identifier:
   1.423 +\begin{itemize}
   1.424 +\item As a key into a table for a database that manages repositories
   1.425 +  on a server.
   1.426 +\item As half of a \{\emph{repository~ID}, \emph{revision~ID}\} tuple.
   1.427 +  Save this information away when you run an automated build or other
   1.428 +  activity, so that you can ``replay'' the build later if necessary.
   1.429 +\end{itemize}
   1.430 +
   1.431 +\subsection{Mimicking Subversion's output}
   1.432 +
   1.433 +Let's try to emulate the default output format used by another
   1.434 +revision control tool, Subversion.
   1.435 +\interaction{template.svnstyle.short}
   1.436 +
   1.437 +Since Subversion's output style is fairly simple, it is easy to
   1.438 +copy-and-paste a hunk of its output into a file, and replace the text
   1.439 +produced above by Subversion with the template values we'd like to see
   1.440 +expanded.
   1.441 +\interaction{template.svnstyle.template}
   1.442 +
   1.443 +There are a few small ways in which this template deviates from the
   1.444 +output produced by Subversion.
   1.445 +\begin{itemize}
   1.446 +\item Subversion prints a ``readable'' date (the ``\texttt{Wed, 27 Sep
   1.447 +    2006}'' in the example output above) in parentheses.  Mercurial's
   1.448 +  templating engine does not provide a way to display a date in this
   1.449 +  format without also printing the time and time zone.
   1.450 +\item We emulate Subversion's printing of ``separator'' lines full of
   1.451 +  ``\texttt{-}'' characters by ending the template with such a line.
   1.452 +  We use the templating engine's \tplkword{header} keyword to print a
   1.453 +  separator line as the first line of output (see below), thus
   1.454 +  achieving similar output to Subversion.
   1.455 +\item Subversion's output includes a count in the header of the number
   1.456 +  of lines in the commit message.  We cannot replicate this in
   1.457 +  Mercurial; the templating engine does not currently provide a filter
   1.458 +  that counts the number of items it is passed.
   1.459 +\end{itemize}
   1.460 +It took me no more than a minute or two of work to replace literal
   1.461 +text from an example of Subversion's output with some keywords and
   1.462 +filters to give the template above.  The style file simply refers to
   1.463 +the template.
   1.464 +\interaction{template.svnstyle.style}
   1.465 +
   1.466 +We could have included the text of the template file directly in the
   1.467 +style file by enclosing it in quotes and replacing the newlines with
   1.468 +``\verb!\n!'' sequences, but it would have made the style file too
   1.469 +difficult to read.  Readability is a good guide when you're trying to
   1.470 +decide whether some text belongs in a style file, or in a template
   1.471 +file that the style file points to.  If the style file will look too
   1.472 +big or cluttered if you insert a literal piece of text, drop it into a
   1.473 +template instead.
