alias: only allow global options before a shell alias, pass later ones through This patch refactors the dispatch code to change how arguments to shell aliases are handled. A separate "pass" to determine whether a command is a shell alias has been added. The rough steps dispatch now performs when a command is given are these: * Parse all arguments up to the command name. * If any arguments such as --repository or --cwd are given (which could change the config file used, and therefore the definition of aliases), they are taken into account. * We determine whether the command is a shell alias. * If so, execute the alias. The --repo and --cwd arguments are still in effect. Any arguments *after* the command name are passed unchanged through to the shell command (and interpolated as normal. * If the command is *not* a shell alias, the dispatching is effectively "reset" and reparsed as normal in its entirety. The net effect of this patch is to make shell alias commands behave as you would expect. Any arguments you give to a shell alias *after* the alias name are passed through unchanged. This lets you do something like the following: [alias] filereleased = !$HG log -r 'descendants(adds("$1")) and tagged()' -l1 $2 $3 $4 $5 $ hg filereleased hgext/bookmarks.py --style compact Previously the `--style compact` part would fail because Mercurial would interpret those arguments as arguments to the alias command itself (which doesn't take any arguments). Also: running something like `hg -R ~/src/hg-crew filereleased hgext/bookmarks.py` when `filereleased` is only defined in that repo's config will now work. These global arguments can *only* be given to a shell alias *before* the alias name. For example, this will *not* work in the above situation: $ hg filereleased -R ~/src/hg-crew hgext/bookmarks.py The reason for this is that you may want to pass arguments like --repository to the alias (or, more likely, their short versions like -R): [alias] own = !chown $@ `$HG root` $ hg own steve $ hg own -R steve

"""syntax highlighting for hgweb (requires Pygments)
It depends on the Pygments syntax highlighting library:

There is a single configuration option::
[web]
pygments_style = <style>
The default is 'colorful'.
