Multiline comment question - SyntaxEditor for Windows Forms Forum

Hi,

Creating a dynamic language and have a quick question. Have the following defined for multiline comments and it works fine. I just would like the casing of the Rem and End Rem tags to be auto corrected. Can anyone offer some assistance??


    <!-- MultiLine Comments -->
    <State Key="MultiLineCommentState" TokenKey="MultiLineCommentDefaultToken" Style="CommentDefaultStyle">
      <!-- Scopes -->
      <Scopes>
        <Scope>
          <RegexPatternGroup Type="StartScope" TokenKey="MultiLineCommentStartToken" Style="CommentDelimiterStyle" PatternValue="Rem {WhitespaceMacro}* {LineTerminatorMacro}" />
          <RegexPatternGroup Type="EndScope" TokenKey="MultiLineCommentEndToken" Style="CommentDelimiterStyle" PatternValue="End {WhitespaceMacro}* Rem" />
        </Scope>
      </Scopes>
      <!-- Patterns Groups -->
      <PatternGroups>
        <RegexPatternGroup TokenKey="MultiLineCommentDefaultToken" PatternValue="{LineTerminatorMacro}" />
      </PatternGroups>
    </State>

I think I need to define it using the ExplicitPatternGroup scope but are not quite sure.

Correct, regular expression patterns don't support auto-case correction.

Hi,

I have a follow-up question in regards to the multi-line pattern above. The speed is currently terrible (5-7 seconds to process) for this when I have around 1500 rows and type Rem on the first row.

Could anyone offer any suggestions to speed it up. I have noted the /* */ on the C# template is very fast, but cannot get something working based on this??

Note: the function need to turn all text inclusive of Rem .. End Rem green and also requires End Rem to be picked up as EndRem (no space).

Any help would be greatly appreciated.

Regards, Matt

Hi Matt,

One thing I can see is that you need work in your token patterns for the contents of the comment state. What you have now is essentially going to make one token for each character, which is probably causing your lag and is eating up a lot more memory than needed. Try changing your pattern from "{LineTerminatorMacro}" to something more like "[^Ee]+". That will make a really long run of characters while still allowing a break for the end scope to be recognized (since it starts with E).
