Include statement created by macro doesn't work

[demotomohiro]

testcode.nim:

echo "echo from testcode.nim"

inclmacro.nim:

import macros

#This include statement works
include "testcode.nim"

dumpTree:
    include "testcode.nim"
#    include "/tmp/tmp/testcode.nim"

macro inclMacro(): untyped =
    result = newStmtList()

    let incl = newNimNode nnkIncludeStmt 
    incl.add newStrLitNode("testcode.nim")
#Using absolute path is fine.
#    incl.add newStrLitNode("/tmp/tmp/testcode.nim")
    result.add incl

    #Output of following echo is equivalent to above dumpTree
    echo treeRepr(result)

inclMacro()

Compiling inclmacro.nim output following error:

$ nim c -r inclmacro.nim

inclmacro.nim(21, 10) template/generic instantiation from here
lib/core/macros.nim(274, 22) Error: cannot open 'testcode.nim'

Plain include statement in inclmacro.nim works without errors, but calling macro that makes equivalent include statement cause "cannot open" error.
When I use inclMacro macro with absolute path of testcode.nim, above error doesn't happen.
It seems current working directory was changed to somewhere when I use include statement in macro.

I tested this issue with Nim 1.0.99.

Nim Compiler Version 1.0.99 [Windows: amd64]
Compiled at 2019-10-17
Copyright (c) 2006-2019 by Andreas Rumpf

git hash: a5ab502f08d11be807c663a9d586b4a4768772dc
active boot switches: -d:release

But still the issue is not fixed.
According to comments in related issue, when import or include statements are created by macro, a relative path in these statement is relative to macros.nim, not relative to the file calling the macro.
If I want to create import or include statements by macro, I have to use absolute path.

workaround: use quote do:, this will set the lineinfo for the include statement correctly.

import macros

include "testcode.nim"

dumpTree:
    include "testcode.nim"

macro inclMacro(): untyped =

    let strLit = newStrLitNode("testcode.nim")

    result = quote do:
      include `strLit`

    echo treeRepr(result)

inclMacro()

output:

echo from testcode.nim
echo from testcode.nim

For slurp/gorge/... I noticed the same behavior. In this case I could make it work by setting the lineinfo of generated AST explicitly to the lineinfo of the call site, see here. Maybe this works for include as well.

[krux02]

callsite doesn't properly work in macros, but year sure that would be a good idea, since workaround sets the lineinfo to the directory of the macro, not the directory of the macro expansion.

BTW, before you base any logic on this behavior, please also commit some tests that ensure that Nim won't break this behaviour without notice. I have a feeling that there might be a breaking change in the future and nobody would notice it.
