By default, this method simply writes to the buffer or stdout.

|
Color mode can be set on the UI class to have the output decorated
|
|
|
with color modifier before being written to stdout.
|
|
|
|
|
|
The color used is controlled by an optional keyword argument, "label".
|
|
|
This should be a string containing label names separated by space.
|
|
|
Label names take the form of "topic.type". For example, ui.debug()
|
|
|
issues a label of "ui.debug".
|
|
|
|
|
|
Progress reports via stderr are normally cleared before writing as
|
|
|
stdout and stderr go to the same terminal. This can be skipped with
|
|
|
the optional keyword argument "keepprogressbar". The progress bar
|
|
|
will continue to occupy a partial line on stderr in that case.
|
|
|
This functionality is intended when Mercurial acts as data source
|
|
|
in a pipe.
|
|
|
|
|
|
When labeling output for a specific command, a label of
|
|
|
"cmdname.type" is recommended. For example, status issues
|
|
|
a label of "status.modified" for modified files.
