The current behaviour for generate-r-packages.R is to delete
packages that have been remove upstream. This patch changes the
behaviour to mark packages as broken rather than removing them.
This has the advantage of never breaking expressions, which
previously occured when a package with overrides in default.nix
was deleted. As a result, the update procedure is simplified,
allowing automated updates to the package tree to run, and
additionally if a package is re-established upstream the previous
overrides still exist.
We are still using Pandoc’s Markdown parser, which differs from CommonMark spec slightly.
Notably:
- Line breaks in lists behave differently.
- Admonitions do not support the simpler syntax https://github.com/jgm/commonmark-hs/issues/75
- The auto_identifiers uses a different algorithm – I made the previous ones explicit.
- Languages (classes) of code blocks cannot contain whitespace so we have to use “pycon” alias instead of Python “console” as GitHub’s linguist
While at it, I also fixed the following issues:
- ShellSesssion was used
- Removed some pointless docbook tags.
* doc: add function argument order convention
Ordering by usage is the de facto ordering given to arguments. It's
logical, and makes finding argument usage easier. Putting lib first is
common in NixOS modules, so it's reasonable to mirror this in nixpkgs
proper. Additionally, it's not a package as such, has zero dependencies,
and can be found used anywhere in a derivation.
* doc: clean up usage of lib
The last snapshot was 4 months ago (2020-08-19). I also found that I needed newer definitions when I was trying to fix the R arrow package.
This update required a couple of manual changes:
1. Removing a few deleted packages from default.nix
2. Renaming the "assert" package to "r_assert" in generate-r-packages.R because "assert" is a keyword in Nix
I used the existing anchors generated by Docbook, so the anchor part
should be a no-op. This could be useful depending on the
infrastructure we choose to use, and it is better to be explicit than
rely on Docbook's id generating algorithms.
I got rid of the metadata segments of the Markdown files, because they
are outdated, inaccurate, and could make people less willing to change
them without speaking with the author.
Reorganize the chapters into parts and reduce the TOC depth to make the
TOC useful again. The top-level TOC is very brief, but that is fine
because every part will have its own TOC.
Section titles of languages/frameworks are also simplified to just
the name of the language/framework.
