Hi Andrey,

I noticed there is a remarkable difference between tm_reduce and tm_maxima.

tm_maxima invokes maxima.bat in a specific case:

#!/bin/sh

if [ -e $TEXMACS_HOME_PATH/plugins/maxima ]; then
  TEXMACS_MAXIMA_PATH="$TEXMACS_HOME_PATH/plugins/maxima/lisp"
else
  TEXMACS_MAXIMA_PATH="$TEXMACS_PATH/plugins/maxima/lisp"
fi
export TEXMACS_MAXIMA_PATH

case $1 in
  cygwin) exec maxima.bat -p "`echo $TEXMACS_MAXIMA_PATH/texmacs-maxima.lisp|cygpath --windows -f -`";;
  *) exec maxima -u $1 -l $2 -p "$TEXMACS_MAXIMA_PATH/texmacs-maxima.lisp";;
esac

On the other hand tm_reduce does NOT invoke redpsl.bat:

#!/bin/sh -f
TEXMACS_REDUCE_PATH="$TEXMACS_PATH/plugins/reduce"
export TEXMACS_REDUCE_PATH
exec redpsl

Is this important?

Thanks,

Daniel Volinski

Hi Peter,

Thank you for you suggestion, I tried it but it did not work.

Hi Andrey,

Thank you for you suggestions, I copied the plugins/reduce/install/reducerc into ~/.reducerc as written in plugins/reduce/doc/reduce.en.tm

but it did not solve the problem: I still get a Busy.. message before the command and nothing happens.

In stand alone Reduce I use CSL Reduce, but If I try it from within TeXmacs and I invoke Reduce I don't know which Reduce I am using. Is there any way to choose which Reduce is invoked from within TeXmacs?

I have redpsl in my PATH but I think it should invoke redpsl.bat not redpsl

redpsl.bat is:

@echo off
set h=%~dp0
set reduce=%h%..
"%reduce%\lib\psl\psl\bpsl.exe" -td 1000 -f "%reduce%\lib\psl\red\reduce.img" %*

In Windows the user home directory ~ is pointed at by environment variable %HOMEPATH%

Thanks again.

Daniel Volinski

Have you copied the file plugins/reduce/install/reducerc to your
~/.reducerc as written in plugins/reduce/doc/reduce.en.tm ?
If you already have .reducerc, you should add the line from
plugins/reduce/install/reducerc, namely

lisp << if getenv("TEXMACS_REDUCE_PATH") then load tmprint >>$

to your own .reducerc.

Do you use psl reduce or csl reduce? The plugin works only with psl
reduce. Is redpsl in your $PATH?

This may be a problem. I know next to nothing about Microsoft Windows.
Where does reduce search for its init file .reducerc in Windows? Can
Windows run shell scripts, in this case tm_reduce? Its content is

#!/bin/sh -f
TEXMACS_REDUCE_PATH="$TEXMACS_PATH/plugins/reduce"
export TEXMACS_REDUCE_PATH
exec redpsl

Does Windows know what is exec?
