Constantine Molchanov 4cf3a95554 Feature: nim book command to produce documentation from Nim-flavored Markdown (#26139)
This PR adds a new Nim compiler command and introduces some improvements
to the docgen suite in general.

1. Adds `nim book`, the new command that takes a directory with
Markdown/ReST files and generates a navigatable, searchable, Nim-first
documentation site.
2. Refactors the default nimdoc.cfg, specifically the part marked with
"needs to be refactored." Code duplication was removed, new overridable
variables were added, quirky logic with the "Group by" switch display
was fixed.

Here's a live demo of a `nim book` produced book:

The original mdBook-powered version:

Related to this PR but valuable on their own:
1. `.. include::` directive has received several improvements:
- You can now include code from line to line, merged:
https://github.com/nim-lang/Nim/pull/26130
- You can now include code with syntax highlighting, merged:
https://github.com/nim-lang/Nim/pull/26146
2. `.. admonition::` directive (and its derivatives like `warning`,
`error`, etc.) got new useful functions:
- You can now set a title to your admonitions, open:
https://github.com/nim-lang/Nim/pull/26159
- You can make admonitions collapsible (useful when you need to include
a large chunk if code), open: https://github.com/nim-lang/Nim/pull/26159

This directory contains the test cases.

Each test must have a filename of the form: t*.nim

Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore top-level tests like tests/tbar.nim.

Specs

Each test can contain a spec in a discard """ ... """ block.

Check out the parseSpec procedure in the specs module for a full and reliable reference

action

Specifies what action this test should take.

Default: run

Options:

  • compile - compiles the module and fails the test if compilations fails.
  • run - compiles and runs the module, fails the test if compilation or execution of test code fails.
  • reject - compiles the module and fails the test if compilation succeeds.

There are certain spec keys that imply run, including output and outputsub.

Categories

Each folder under this directory represents a test category, which can be tested by running koch tests pcat <category> (or cat to avoid parallel testing, which is slower).

The folder dll contains simple DLL tests.

The folder realtimeGC contains a test for validating that the realtime GC can run properly without linking against the nimrtl.dll/so.
