Language definition question - SyntaxEditor for Windows Forms Forum

Posted 20 years ago by meathook - Genesys Telecommunications

I use the SyntaxEditor control in a development tool that uses an extended form of TCL. In a version 1.x language file, how do you support escaped newlines?

For example:

#set x 1 \
set y 2

would, according to my language file, treat the first line as a comment. This is due to the fact that TCL is a line delimited language. However, the parser treats the \ as an escape. Since the newline is next, it is escaped and the next line also is part of the comment.

I can provide my language file if necessary.

If you do a regular expression it would probably be something like:
\\\n

As it is right now, I use the LineTerminatorMacro for my end of comment token. How could I modify this to ignore the escaped newline?

You have to add a token that consumes that end of line character. That's why adding one for \\\n would probably work.

Thanks for your help.

The latest build of this product (v25.1.0) was released 20 days ago, which was after the last post in this thread.
