Nim: [TODO] `import ./[foo1,foo2]` gives error; `import ./bar/[foo1,foo2]` works

[timotheecour]

[Araq]

Where is that documented to work?

[timotheecour]

it should be (IMO) based on orthogonality of features:

import bar/foo #ok
import ./foo #ok: foo is relative to ./
import ./foo/[bar1, bar2] #ok

import bar/[foo] #ok
import ./[foo] # error
import ./[bar1, bar2] # error

here's an example where it's useful to have:
in compiler/nim.nim:

import
  commands, lexer, condsyms, options, msgs, nversion, nimconf, ropes,
  extccomp, strutils, os, osproc, platform, main, parseopt,
  nodejs, scriptconfig, idents, modulegraphs, lineinfos

it's not clear which of these are in ./ (ie, compiler) vs std/ (eg strutils)

eg, once https://github.com/nim-lang/Nim/pull/8614 (Nim now allows modules with same name in a package) is implemented, keeping that ambiguitiy is not good, and following code is better (IMO):

import
  ./[commands, lexer, condsyms, options, ... ]
  std/[strutils, os, osproc, ...]

1. Dots are ugly.
2. Orthogonality of features means you need to write "." / [foo, bar] which works.

[Clyybber]

@Araq

./somepath

is standard and

"." / somepath

is much more ugly IMO.

[Araq]

There is no "standard", Nim is its own programming language.

So you want two ways to do the same thing? This is really unnecessary.

[timotheecour]

/cc @dom96

also this:

import ./foo/[bar1, bar2] # works
import ../foo/[bar1, bar2] # works
import ./[bar1, bar2] # error
import ../[bar1, bar2] # error

So you want two ways to do the same thing? This is really unnecessary.

we already have 2 ways to use import with and without quotes. Quotes is typically used for cases where non-quotes would result in error, eg from the docs:

import "gfx/3d/somemodule" # in quotes because '3d' is not a valid Nim identifier

and the overwhelming majority (98% using following coarse measurement) of import uses non-quotes:

rg -A1 '\bimport '| wc -l
    4180
rg -A1 '\bimport '| grep '"'| wc -l
      93

Furthermore the docs says it should be allowed:
The syntax ``import dir / [moduleA, moduleB]`` can be used to import multiple modules from the same directory.
. is a valid directory

it's just a bug, and it's probably easy to fix.
