nim-lang/Nim

Nim is a compiled, garbage-collected systems programming language which has an excellent productivity/performance ratio. Nim's design focuses on efficiency, expressiveness, elegance (in the order of priority).

getCurrentDir is just current dir (more or less $PWD); getProjectPath is just parentDir(abspath(foo)) where foo is the module in cmd line nim c foo

@kaushalmodi

hmm, thanks, so as I was doing nim c draw.nim while in the draw/ dir, they ended up being the same

need to note this down

Timothee Cour

@timotheecour

(Or, PR :) )

Kaushal Modi

@kaushalmodi

PR where?

Timothee Cour

@timotheecour

under getProjectPath in macros.nim

Kaushal Modi

@kaushalmodi

I need to find a concise way to articulate this

I was unable to explain myself without that dummy /a/b example

Timothee Cour

@timotheecour

best is 1 example where currentdir, getProjectPath and currentSourcePath are all different. then it’s crystal clear.

(WITH the dummy example is best)

Kaushal Modi

@kaushalmodi

ok, will work on it

(or u can help w nimterop :) )

@FromIRC

<shashlick> sorry missed the conversation

<shashlick> so you are having trouble pointing to the source?

Kaushal Modi

@kaushalmodi

shashlick: @timotheecour helped me sort it out

solution: https://ptpb.pw/WRzv/nim

the problem was that I needed that include/search path to stay static to the dir containing that nim file regardless of from where I imported it

From IRC (bridge bot)

@FromIRC

<shashlick> i don't know why you need that cause my tsoloud.nim works fine with relative paths

<shashlick> okay i see - if you import the nim wrapper, it stops working cause you are now elsewhere

Kaushal Modi

@kaushalmodi

that eggx.h has include with <foo.h>

so I need to add the same path to cInclude too

Timothee Cour

@timotheecour

that PR im working on is relevant for this: https://github.com/genotrance/nimterop/pull/70/files#diff-f10b365dce6d4c3a1d4093c8d9e77c65

i’m now using abs paths and makes code simpler

From IRC (bridge bot)

@FromIRC

<shashlick> @kaushalmodi - i used sourcepath in the tree-sitter wrapper too - https://github.com/genotrance/nimterop/blob/master/nimterop/treesitter/runtime.nim

Kaushal Modi

@kaushalmodi

shashlick: It's just that I discovered currentSourcePath() today :)

From IRC (bridge bot)

@FromIRC

<shashlick> ya that was a big one even in nimgen days

<shashlick> feel free to join https://gitter.im/nimgen/Lobby to chat about nimterop

Kaushal Modi

@kaushalmodi

will do, thanks

btw can someone point out why that second import line doesn't work? https://ptpb.pw/ObL6/nim

b/bar.nim(2, 31) Error: undeclared identifier: 'currentSourcePath'

Timothee Cour

@timotheecour

because of this:
[0 ] lib/system.nim:3978:10 |template currentSourcePath*: string = instantiationInfo(-1, true).filename

it’s defined in system.nim :)

Kaushal Modi

@kaushalmodi

sorry, I need to sleep it seems

I visited the manual like 5 times, but didn't spot that I was opening system.html

and thank you

<shashlick> how's the actual nim render

<shashlick> with nimterop? is the wrapper working?

Kaushal Modi

@kaushalmodi

@timotheecour a minimal example showing the path differences:

km²~/sandbox/:nim/paths> ls --tree                                                   01/27 11:18pm
./
└── a/
   ├── b/
   │  └── bar.nim
   └── foo.nim
km²~/sandbox/:nim/paths> cat a/foo.nim                                               01/27 11:18pm
import b/bar
km²~/sandbox/:nim/paths> cat a/b/bar.nim                                             01/27 11:18pm
from macros import getProjectPath
from os import getCurrentDir, parentDir # doesn't work

const
  sDir = currentSourcePath.parentDir()
  pDir = getProjectPath()
let
  cDir = getCurrentDir()

echo "Source path = ", sDir
echo "Project path = ", pDir
echo "Current path = ", cDir

shashlick: if that question was for me, I just got that wrapper to compile

now working on translating some C code to Nim in that wrapper

Timothee Cour

@timotheecour

@kaushalmodi please report all issues u encounter in the bug tracker (after checking they’re not dups :)

Kaushal Modi

@kaushalmodi

will send a PR for this to an appropriate place in the manual

(that "doesn't work" in the comment is old, doesn't apply any more)

Timothee Cour

@timotheecour

ya that example (prettified a bit and with doAssert instead of echo) would be fine in doc (not runnableExamples but as code block)

<yunfan> hi i was on alpinelinux v3.8.1, and i met a problem while installing nim using choosenim script

<yunfan> the downloaded file exsts at /tmp directory and i had gave it executing permission, but still gave me file not exist while i execute it by manual

<leorize> yunfan: maybe you should try building it manually?

<leorize> oh, and choosenim might have been compiled with glibc, so it wouldn't work on your device

<yunfan> leorize: got it, alpine were upon on musl
