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.

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.
