[texworks] several replacements

[Paul A Norman]

P.S.

If you are going to processing a number of documents with similar but
different settings (as in changing your custom LaTeX to meet a publisher's
requirements), you could change the script to actually choose the version
of  "*myReplacements.txt*"  to use...

http://twscript.paulanorman.com/docs/html/getOpenFileNameQString.html
and
http://twscript.paulanorman.com/docs/html/readFile.html

And if you want   "*myReplacements.txt*"    to allow for line(s) in it to
be temporarily suspended, or for comments, start the line with a %

\text{A} -> A

%\text{B} -> B

\text{i} -> \ii

% put a note/comment here

\text{e} -> \e

\Ouv -> \ouv

\text{B} -> B  would not get processed.

and change..

*function altertext*(txt)

  {

    for (count in myReplacementList)

       {

        if (myReplacementList[count].substr(0,1) == "%")

        {

        continue;

        }



var actionThis = myReplacementList[count].split(" -> ");

 ... the  rest of function
}

Also bulk alterations in "*myReplacements.txt*"  could be for anything not
just LaTeX
