nim-lang / Nim

Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

incremental compilation breaks strformat with enums #22226

Closed Rellikeht closed 1 year ago

Rellikeht commented 1 year ago

Description

This is minimal example of code that generates compile error when using --incremental:on

import strformat

type E = enum a

echo fmt"{a}"

Nim Version

Nim Compiler Version 1.9.5 [Linux: amd64] Compiled at 2023-07-05 Copyright (c) 2006-2023 by Andreas Rumpf

git hash: 86ff37fab8656f7acd08fc9c3fa237f9e022dbf4 active boot switches: -d:release

Current Output

Error: 'newNimNode' can only be used in compile-time context

Expected Output

This should compile

Possible Solution

No response

Additional Information

It does that too on stable versions (1.6.x)

!nim c --incremental:on

import strformat
type E = enum a
echo fmt"{a}"

Development of IC is on hold until 2.0 has been released. And we know it doesn't work, thanks.
