* Clarifies experimental / parallel on manual.rst
Details:
Calling `useParallel()` in example fails with compiler error
Error: 'parallel' section without 'spawn'
Adding `spawn` causes error:
Error: internal error: (filename: "ccgexprs.nim", line: 1032, column: 17)
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c <file>
Therefore a separate proc, `threadedEcho`, is added for the echo'ing
of the string, which allows the example to build, however, `sync()`
must be added so that the "echo in parallel" strings will actually
be shown on the terminal. Otherwise, the program will spawn of the
threads and exit before they can return to the main thread.
* Fixes and clarifies example for threading in manual.rst
Issue:
Calling useParallel() in example failed with compiler error
`Error: 'parallel' section without 'spawn'`
Adding spawn yielded compiler error:
```bash
Error: internal error: (filename: "ccgexprs.nim", line: 1032, column: 17)
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c
```
Proposed Solution:
- Separate proc, threadedEcho, is added for the echo'ing
of the string, which allows the example to build
- Added the thread number so that it can demonstrate that sometimes
threads which were started sooner, come back after threads which
were started later.
* Fix many broken links
Note that contrary to what docgen.rst currently says, the ids have
to match exactly or else most web browsers will not jump to the
intended symbol.
* Prefer relative links for Nim documentation
This is more friendly to those browsing the documentation without
a network connection. The nim-doc package in Debian allows this,
for example.
Also, the domain name being used was not consistent. It could have
been either nim-lang.org or nim-lang.github.io, and those reading
the stable docs could have found themselves suddenly reading the
devel docs instead.
* koch.rst: remove link to nonexistent section
* manual.rst: remove unintended link
cast[T](0) is interpreted as a link to id 0 with text T, so escape
the opening parentheses to display the intended output.
* asyncstreams: replace unintended link with emphasis
* Fix word wrapping
* new .gensym implementation
* make astspec test green again
* introduce a --useVersion switch to group compatibility switches
* fixes#10180
* fixes#11494
* fixes#11483
* object constructor fields and named parameters are also not gensym'ed
* disabled broken package
* IC: C codegen is aware of IC
* manual: minor change to make VSCode's RST plugin render it properly
* IC: minor refactoring
* testament: code refactorings
* rodutils: removed dead code
* IC: always build the compiler with the IC feature
* IC: C codegen improvements
* IC: implement the undocumented -d:nimMustCache option for testing purposes
* IC: added first basic tests
* IC: extensive testing of the deserialization feature
* testament: refactoring; better IC tests
* IC: removes 'nimMustCache' flag; readonly does the same
* testament: minor refactoring
* update Nimble version
* testament: removed dead code and imports; IC: added simple test
* IC: progress
