querySetting(nimcacheDir) points to non-existing folder for nimsuggest

[arkanoid87]

https://github.com/PMunch/futhark/blob/875a7f5cf727483bc4c4d394f7d3c23699002aa8/src/futhark.nim#L456

querySetting(nimcacheDir) seems to hold different values:

• if it is queried by nimble at compile time: /home/jack/.cache/nim/nimmap_d
• if it is queried by nimsuggest: /home/jack/.cache/nim/nimmap_check

As a result futhark works at build time and at runtime, but nimsuggest fails and as a result code completion and error checking is not available for all imported C code.

opir -I/usr/lib/clang/10/include -I/usr/include/gdal /home/jack/.cache/nim/nimmap_check/futhark-includes.h
Fatal: '/home/jack/.cache/nim/nimmap_check/futhark-includes.h' file not found
Tried to parse: /home/jack/.cache/nim/nimmap_check/futhark-includes.h
With arguments: -I/usr/lib/clang/10/include -I/usr/include/gdal
Unable to parse translation unit succesfully. Quitting

Running: opir -I/usr/lib/clang/10/include -I/usr/include/gdal /home/jack/.cache/nim/nimmap_check/futhark-includes.h [User]

As a workaround, I've been copying the futhark generated nim file into project folder, switching from futhark to import when needed like in:

when not defined(useFuthark):
  import gdal
else:
  import futhark
  importc:
    absPath "/usr/lib/clang/10/include"
    path "/usr/include/gdal"
    "gdal.h"
    "ogr_core.h"
    "ogr_api.h"

this ugly fix solves the problem, as long as you don't build release

cacheDir = querySetting(nimcacheDir).replace("_check","_d")

[arkanoid87]

I wonder why I realized this with vscode but you said to have futhark autocompletion out of the box with vim. Shouldn't both solution be based on nimsuggest?

[PMunch]

Hmm, this appears to be something that VSCode does or the plugin passes to nimsuggest. On my machine I don't have any _check folders in my ~/.cache/nim folder and as long as I've built the library once I get completion in Vim.

[arkanoid87]

I'm not finding "check" suffix in saem vscode extension, but I see it calling "nim check", so it might be that.

I also don't have the myproj_check folder, just myproj_d and myproj_r, not sure if that folder lives for just a moment and then gets deleted, or if it is a different kind of deal

[arkanoid87]

I can confirm that this happens in nim check

import std/[compilesettings]

static:
  echo querySetting(nimcacheDir)

nim c -r main.nim

/home/jack/.cache/nim/vscodecache_d

nim check main.nim

/home/jack/.cache/nim/vscodecache_check

I think your experience with nimlsp may help track the issue in https://github.com/saem/vscode-nim

[arkanoid87]

I've created a minimal test to replicate the problem

vscodecache.nim

import std/[os, compilesettings, macros]

const cacheFile = querySetting(nimcacheDir) / "test.nim"

static:
  writeFile(cacheFile, "let foo* = 42")

macro loadFromCache: untyped =
  return quote do:
    include `cacheFile`

loadFromCache()
echo foo

nim c -r vscodecache.nim

42

vscode error == nim check vscodecache.nim
