Conversion of shell script to batch file discards comments

The title says it all.

This occurs on Linux Mint 21.3. If you want sample code in which this occurs, I attached such a file for issue #72.

[rburkey2005]

But in case it doesn't work the same way when you try it, my shell script starts with

#!/bin/bash
# This script can be used for Linux or Mac OS to perform a digital simulation
# of a single logical module, or portion thereof.  It should be executed from
# the folder containing the schematic file (module.kicad_sch) and a 
# user-created partial-testbench file called tb.v.
#
# Usage:
#       simulateModule MODULENAME [NETLISTFILE]
# where MODULENAME is one of the names of Block II AGC logic modules:
# A1, A2, A3, ..., A24.  The optional parameter can give the name of a netlist
# file.  If it is not present, then KiCad v7 or later is required so that
# we can generate the netlist file ourself from the command line.

# First, parse the command line and perform sanity checks.

if [ "$1" = "" ]
then
        echo "No module number (A1, A2, ..., A24) given"
        exit 1
else
        modulenum=$1
fi

and in the batch file this turns into

@echo off

IF "%~1" "=" "" (
  echo "No module number (A1, A2, ..., A24) given"
  exit "1"
) ELSE (
  SET "modulenum=%~1"
)

This is no really possible based on the current stack - mainly because the parsing does not preserve comments - see: vorpaljs/bash-parser#62

It certainly seems possible, at least for full-line comments. Roughly speaking, a preprocessing step could convert full-line comments like

# This is my comment

into environment-variable assignments like

_comment_="This is my comment"

Conversion from shell-script to batch-file could then proceed normally, and afterward a postprocessing step could do the reverse conversion from

SET _comment_="This is my comment"

to

REM This is my comment
