metagn 037f87d904 top-down type inference, implements rfc 149 (#20091)
* micro implementation of rfc 149

refs https://github.com/nim-lang/RFCs/issues/149

* number/array/seq literals, more statements

* try fix number literal alias issue

* renew expectedType with if/case/try branch types

* fix (nerf) index type handling and float typed int

* use typeAllowed

* tweaks + const test (tested locally) [skip ci]

* fill out more of the checklist

* more literals, change @ order, type conversions

Not copying the full call tree before the typedesc call check
in `semIndirectOp` is also a small performance improvement.

* disable self-conversion warning

* revert type conversions (maybe separate op later)

* deal with CI for now (seems unrelated), try enums

* workaround CI different way

* proper fix

* again

* see sizes

* lol

* overload selection, simplify int literal -> float

* range, new @ solution, try use fitNode for nil

* use new magic

* try fix ranges, new magic, deal with #20193

* add documentation, support templates

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.

cmd

Specifies the Nim command to use for compiling the test.

There are a number of variables that are replaced in this spec option:

  • $target - the compilation target, e.g. c.
  • $options - the options for the compiler.
  • $file - the filename of the test.
  • $filedir - the directory of the test file.

Example:

discard """
  cmd: "nim $target --nimblePath:./nimbleDir/simplePkgs $options $file"
"""

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.
