hgweb: use util.sortdict for archivespecs
Thus we allow dict-like indexing and "in" checks, and also preserve the order
of archive types and can generate links in a certain order (so
requestcontext.archives is no longer needed).

'''colorize output from some commands
The color extension colorizes output from several Mercurial commands.
For example, the diff command shows additions in green and deletions
in red, while the status command shows modified files in magenta. Many
other commands have analogous colors. It is possible to customize
these colors.
Effects
-------
Other effects in addition to color, like bold and underlined text, are
also available. By default, the terminfo database is used to find the
terminal codes used to change color and effect. If terminfo is not
available, then effects are rendered with the ECMA-48 SGR control
function (aka ANSI escape codes).
The available effects in terminfo mode are 'blink', 'bold', 'dim',
'inverse', 'invisible', 'italic', 'standout', and 'underline'; in
ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and
'underline'. How each is rendered depends on the terminal emulator.
Some may not be available for a given terminal type, and will be
silently ignored.
If the terminfo entry for your terminal is missing codes for an effect
or has the wrong codes, you can add or override those codes in your
configuration::
[color]
terminfo.dim = \E[2m
where '\E' is substituted with an escape character.
Labels
------
Text receives color effects depending on the labels that it has. Many
default Mercurial commands emit labelled text. You can also define
your own labels in templates using the label function, see :hg:`help
templates`. A single portion of text may have more than one label. In
that case, effects given to the last label will override any other
effects. This includes the special "none" effect, which nullifies
other effects.
Labels are normally invisible. In order to see these labels and their
position in the text, use the global --color=debug option. The same
anchor text may be associated to multiple labels, e.g.
[log.changeset changeset.secret|changeset: 22611:6f0a53c8f587]
The following are the default effects for some default labels. Default
effects may be overridden from your configuration file::
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.tab =
diff.trailingwhitespace = bold red_background
# Blank so it inherits the style of the surrounding label
changeset.public =
changeset.draft =
changeset.secret =
resolve.unresolved = red bold
resolve.resolved = green bold
bookmarks.active = green
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
tags.normal = green
tags.local = black bold
rebase.rebased = blue
rebase.remaining = red bold
shelve.age = cyan
shelve.newest = green bold
shelve.name = blue bold
histedit.remaining = red bold
Custom colors
-------------
Because there are only eight standard colors, this module allows you
to define color names for other color slots which might be available
for your terminal type, assuming terminfo mode. For instance::
color.brightblue = 12
color.pink = 207
color.orange = 202
to set 'brightblue' to color slot 12 (useful for 16 color terminals
that have brighter colors defined in the upper eight) and, 'pink' and
'orange' to colors in 256-color xterm's default color cube. These
defined colors may then be used as any of the pre-defined eight,
including appending '_background' to set the background to that color.
Modes
-----
By default, the color extension will use ANSI mode (or win32 mode on
Windows) if it detects a terminal. To override auto mode (to enable
terminfo mode, for example), set the following configuration option::
[color]
mode = terminfo
Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will
disable color.
Note that on some systems, terminfo mode may cause problems when using
color with the pager extension and less -R. less with the -R option
will only display ECMA-48 color codes, and terminfo mode may sometimes
emit codes that less doesn't understand. You can work around this by
either using ansi mode (or auto mode), or by using less -r (which will
pass through all terminal control codes, not just color control
codes).
On some systems (such as MSYS in Windows), the terminal may support
a different color mode than the pager (activated via the "pager"
extension). It is possible to define separate modes depending on whether
the pager is active::
[color]
mode = auto
pagermode = ansi
If ``pagermode`` is not defined, the ``mode`` will be used.
