missing quotation marks

[bigwasp]

Just tried nim-2.0.0 on Linux Mint 21.2 (Ubuntu 22.04 based)

import shell

shell:
  one:
    mkdir foo
    pushd foo
    echo "Hallo\nWorld" > test.txt
    pipe:
      cat test.txt
      grep H
    popd
    rm foo/test.txt
    rmdir foo

It seems that the quotation marks got lost.
Have i done something wrong?

Just compiled with nim c {file,nim}

Throws following:

ShellCmd: mkdir foo && pushd foo && echo Hallo
World > test.txt && cat test.txt | grep H && popd && rm foo/test.txt && rmdir foo
shell> /bin/sh: 1: pushd: not found
shell> /bin/sh: 2: World: not found
Error when executing: mkdir foo && pushd foo && echo Hallo
World > test.txt && cat test.txt | grep H && popd && rm foo/test.txt && rmdir foo
err>

Thanks for the report!

Hmm, I think it's a mix of two things:

1. I must have written this example before we switched to startProcess. Using startProcess we're not running in a normal terminal (so using bash for example), but rather with /bin/sh. pushd and popd are specific bash (and other posix extending terminal emulator) features. So that's why it says pushd: not found. That's a regression in some sense, of course. Need to think about this.
2. it really seems like I broke the handling of strings. I guess in the past this correctly redirected to text.txt with two lines. In order for it to work, I now need to manually hand an explicit string:

So this works:

import shell

shell:
  one:
    mkdir foo
    cd foo
    "echo \"Hallo\nWorld\" > test.txt"
    pipe:
      cat test.txt
      grep H
    cd ".."
    rm foo/test.txt
    rmdir foo

I suppose I changed the string handling to make precisely this work. The idea being that a Nim string should just be handed "as is" in terms of the content to the shell. The example implies however, that the entire thing is handed as written to the shell. The latter is convenient in some cases (like here), but restricting in others (in the more common ones). Because we really need to be able to overwrite the limitations of the Nim grammar for many practical uses cases.
