wireproto: syntax for encoding CBOR into frames...
wireproto: syntax for encoding CBOR into frames We just vendored a library for encoding and decoding the CBOR data format. While the intent of that vendor was to support state files, CBOR is really a nice data format. It is extensible and compact. I've been feeling dirty inventing my own data formats for frame payloads. While custom formats can always beat out a generic format, there is a cost to be paid in terms of implementation, comprehension, etc. CBOR is compact enough that I'm not too worried about efficiency loss. I think the benefits of using a standardized format outweigh rolling our own formats. So I plan to make heavy use of CBOR in the wire protocol going forward. This commit introduces support for encoding CBOR data in frame payloads to our function to make a frame from a human string. We do need to employ some low-level Python code in order to evaluate a string as a Python expression. But other than that, this should hopefully be pretty straightforward. Unit tests for this function have been added. Differential Revision: https://phab.mercurial-scm.org/D2948

Some Mercurial commands can produce a lot of output, and Mercurial will
attempt to use a pager to make those commands more pleasant.
To set the pager that should be used, set the application variable::
[pager]
pager = less -FRX
If no pager is set in the user or repository configuration, Mercurial uses the
environment variable $PAGER. If $PAGER is not set, pager.pager from the default
or system configuration is used. If none of these are set, a default pager will
be used, typically `less` on Unix and `more` on Windows.
.. container:: windows
On Windows, `more` is not color aware, so using it effectively disables color.
MSYS and Cygwin shells provide `less` as a pager, which can be configured to
support ANSI color codes. See :hg:`help config.color.pagermode` to configure
the color mode when invoking a pager.
You can disable the pager for certain commands by adding them to the
pager.ignore list::
[pager]
ignore = version, help, update
To ignore global commands like :hg:`version` or :hg:`help`, you have
to specify them in your user configuration file.
To control whether the pager is used at all for an individual command,
you can use --pager=<value>:
- use as needed: `auto`.
- require the pager: `yes` or `on`.
- suppress the pager: `no` or `off` (any unrecognized value
will also work).
To globally turn off all attempts to use a pager, set::
[ui]
paginate = never
which will prevent the pager from running.
