Re: [isabelle] Elbe with Symbols

Hello,

the next version of the Elbe software will contain a more comfortable
editor for Isabelle source files. It is planned to have a fully
functional editor for special characters. The sources will stay ASCII
files and in the editor the special chars will be represented by their
glyphs. On save these glyphs will become substituted by ASCII symbols.
You can have a look at the current layout under

Two questions arose:

a) are the chars shown all chars used in Isabelle?
b) What does <^const> mean?  I did not find it in the table ..

There are some explanations and specifications on this in
the isar-ref manual (appendix B) and the implementation manual (section
1.2.1), see also http://isabelle.in.tum.de/documentation.html

It is also advisable to check how the Isabelle/jEdit Prover IDE handles this issue -- there is a brief overview in the README on startup. This is based on a general module in Isabelle/Scala, see also http://isabelle.in.tum.de/repos/isabelle/file/Isabelle2011-1/src/Pure/General/symbol.scala
