AvalonEdit XSHD-Ruleset (for tex)
I'm using the AvalonEdit control in and I have a small problem with the xshd-ruleset (for tex):
There is a section in the original file 'syntaxdefinition for TeX document 2001 by Mike Krueger (gleaned from Jedit)' about special keywords and I'm wondering how to use them right.
<!-- some commands must be handled specially -->
<KeyWords name = "Keyword1" bold = "false" italic = "false" color = "Blue">
<Key word = "\$" />
<Key word = "\\" />
<Key word = "\%" />
</KeyWords>
I though that keywords will be colored blue and are handled only by this, but other rules are handling parts these keywords, too. e.g.
<Span name = "LineComment" color = "SlateGray" stopateol = "true">
<Begin>%</Begin>
</Span>
So if you have "\%" in your text everything beyond the '\' will be colored gray...
It would be very nice, if that keywords forbid the rules e.g. for '$' and '%' if there is a '\' before.
What I have to do? Or didn't I understand the rulesets...
EDIT:
"\\" is handled by the keyword1 entry. The < MarkFollowing ... is not used for "\\" but the < Span 开发者_JS百科... are still doing its highlighting for "\$" and "\%".
I found
escapecharacter="\"
but it's not working.
EDIT2:
With the new syntax highlighting definition the problem is the same I think. I compared my tex highlighting with the c# highlighting. In c# we have:
<Span color="String">
<Begin>"</Begin>
<End>"</End>
<RuleSet>
<!-- span for escape sequences -->
<Span begin="\\" end="."/>
</RuleSet>
</Span>
I don't use sharpdevelop, but I think it's working, that the highlighting doesn't fail, if I'm escaping characters like ". So in my file it's similar to that, like
<Span foreground="#FF708090" fontWeight="normal" fontStyle="italic">
<Begin>%</Begin>
<RuleSet>
<Span begin="\\" end="." />
</RuleSet>
</Span>
but it's not working... Maybe there is a problem, because the escape-character is a < Rule > ?
Try porting the file to the new format, see http://community.sharpdevelop.net/forums/p/10468/28886.aspx#28886 for details.
In the new format, you can use regular expression in rules, which should work a lot better than trying to fake TeX constructs using Keywords/MarkFollowing.
On your EDIT2: If you want the \ to be an escape sequence inside TeX code (in front of the comment, as opposed to being an escape symbol inside the string/comment), then use the escaping span inside the main ruleset:
<Span begin="\\" end="."/>
<Span foreground="#FF708090" fontWeight="normal" fontStyle="italic">
<Begin>%</Begin>
</Span>
