Syntax Highlighting Issue - 4.0 - SyntaxEditor for Windows Forms Forum

Posted 19 years ago by Matthew Smith - Developer, One Plus One Solutions Pty Limited

Hi,

The very last word in a document is not coloring correctly unless you add a space or carriage return to the next line (by adding a new row).

Steps to reproduce:

* Start the SDI Editor Application
* Set the Language to VB.Net
* Line 22 - keyword Function is not colored

Appears to affect all languages ie. VBScript, JScript, SQL (the ones I checked anyway)

Found the problem... in v4.0 look-aheads and look-behinds now support zero-width assertions. In v3.1 they didn't. So in v3.1, we had look-aheads and look-behinds always return true if you were at the start or end of the document respectively. This is no longer true since we have correct behavior in v4.0.

So you need to change things like this:
LookAhead="{NonWordMacro}"

to this:
LookAhead="{NonWordMacro}|\z"

in the v4.0 dynamic language defs. That is saying match either a non-word character or the end of the document.
