Also restructures the mode determination as discussed on IRC.
I tried to simplify the code too, while keeping the original
semantics except for the case of --color=always.
This fixes the color extension not working with pager (broken in
cab5f9b68e3a). The pager extension already sets ui.formatted=True to
allow this use case.
Without this change, curses complains when invoked in certain contexts
because stdout isn't a tty (such as emacs integration) but we ask it
to check for various bits of information from terminfo.
Using terminfo instead of hard-coding ECMA-48 control sequences provides a
greater assurance that the terminal codes are correct for the current
terminal type; not everything supports the ANSI escape codes.
It also allows us to use a wider range of colors when a terminal emulator
supports it (such as 16- or 256-color xterm), and a few more non-color
attributes, such as the ever-popular blink.
This complicates the code a bit, since attributes need to be masked together
correctly before they are applied. Perhaps the code should be redesigned at
some point, but this works well for now.
Currently, a number of commands and help topics mention the user hgrc
file in different ways. Among these are following:
1. .hgrc - "please specify your commit editor/username in your .hgrc
file", bookmarks, color, hgk, pager, hg help environment
2. $HOME/.hgrc - hg help paths, hgrc(5), hg(1)
3. ~/.hgrc - hgrc(5)
In addition to being inconsistent, none of these make sense on
Windows. This patch replaces the above with a more general term of
"[your] configuration file".
If your application is being built as a non-console application,
stdout is not a valid handle and raises an exception:
pywintypes.error: (6, 'DuplicateHandle', 'The handle is invalid.')
Alternatively, non-console applications launched outside of a
console will return None from GetStdHandle instead of raising an
exception.
This commit updates the branches command to use ui.label for the branch names
and the changeset. This implementation allows assigning colors to the four
states of a branch: active, closed, current and inactive. While you can
configure color for the four states, only current and closed have default colors
of green and black bold respectively.
Without this fix, any calls to write_err would go to stdout instead of
stderr, and calls during pushbuffer would cause unpack ValueErrors on
popbuffer.
This resolves the issue of hg cmd --mq not being colorized. This was due
to color wrapping only the instance of ui passed to dispatch._runcommand(),
which isn't the same ui object that mq.mqcommand() receives. After dispatch
calls extensions.loadall(), it makes sure any changes to ui.__class__ in
uisetup are propagated.
progress is updated to wrap ui in the same manner because wrapfunction
doesn't play well when ui.__class__ has been replaced by another extension
(orig will point to the old class method instead of color's).
this helps users to know what kind of option is:
- no value is required(flag option)
- value is required
- value is required, and multiple occurrences are allowed
each kinds are shown as below:
-f --force force push
-e --ssh CMD specify ssh command to use
-b --branch BRANCH [+] a specific branch you would like to push
if one or more 3rd type options are shown, explanation for '[+]' mark
is also shown as footnote.
Some implementations of ui.label() (HTML versions in particular) must escape
the provided text and then markup the text with their tags. When this marked
up text is then passed to ui.write(), we must label the text as 'ui.labeled'
so the implementation knows not to escape it a second time (exposing the initial
markup).
This required the addition of a 'ui.plain' label for text that is purposefully
not marked up.
I was a little pedantic here, passing even ' ' strings to ui.label() when it
would be included with other labeled text in a ui.write() call. But it seemed
appropriate to lean to the side of caution.
Introduces color.mode configurable with values 'auto', 'ansi', or 'win32'. Any
other value disables coloring. When 'auto' is selected, the win32 console
method will be used if the win32console Python module is detected (requires
pywin32 to be installed).
Currently, less -R doesn't support colors spanning multiple lines; only
the first line will be colorized.
Instead of allowing colors to span multiple lines, the color extension
now applies colors to each line it receives, even when ui.write() is
given multiple lines in one call.
By overriding ui.write(), ui.write_err(), ui.popbuffer(), and ui.label(),
the color extension can avoid parsing command output and simply colorize
output based on labels.
As before, the color extension provides a list of default colors for
core commands/labels. Other extensions can provide their own defaults by
specifying a colortable dict (similar to cmdtable).
In this process, --color is promoted to a global option and the deprecated
--no-color option is removed.
Passing the --color and --no-color parameter to the wrapped function
can cause a invalid argument exception if the wrapped function doesn't
accepts a **opts dict.
