Lexems with same BeginBlock and different EndBlock

[Steffen Schurg, SD-ES]

Hello,

I've got difficulties to get complex lexems highlighted correctly, when different lexems have the same BeginBlock:

------------------------
lexem BeginBlock="IF" EndBlock="GOTO" Type="KeyWord" IsComplex="true" IsCollapsable="false"
SubLexems/
References/
/lexem

lexem BeginBlock="IF" EndBlock="END_IF" Type="KeyWord" IsComplex="true" IsCollapsable="true" CollapseName="IF STATEMENT" Indent="true" IndentationGuideline="true"
SubLexems
lexem BeginBlock="THEN" Type="KeyWord"
lexem BeginBlock="ELSE" Type="KeyWord"
lexem BeginBlock="ELSIF" Type="KeyWord"
lexem BeginBlock="\n" IsBeginRegex="true"
/SubLexems
References/
/lexem

lexem BeginBlock="GOTO" Type="KeyWord">
SubLexems/
References/
/lexem
------------------------

Is there a possibility to get the following highlighted correctly?

------------------------
IF a < b THEN
GOTO label1
ELSIF a > b THEN
GOTO label2
END_IF

IF a < b GOTO label3

IF a < b THEN
a := 4
ELSE
b := 5
END_IF
------------------------

Thanks in advance!

Hi Steffen,

Thank you for your interest in Syncfusion products.

We have created sample as you expected. Please download the sample from the below link:

You can get more regarding this from the Browser sample from the below link:

Please let me know if you have any other queries.

Hello Bhuvana,

thank you for your quick reply!

Unfortunately your example doesn't fully solve my issue as you presumend the GOTO statement is only a separate lexem. But there is a IF ... GOTO statement in that language as well.

To be clear three different statements exist:

- IF THEN [ELSIF THEN ] [ELSE ] END_IF
- IF GOTO
- GOTO

The main problem is to get the IF-lexem ended either with END_IF or with GOTO

It would be kind if you could give an example for that as well.

Best Regards,
Steffen

Hi Steffen,

Thanks for the update.

Here is the code snippet for the below conditions
1. IF THEN [ELSIF THEN ] [ELSE ] END_IF

CollapseName="IF..END_IF" >








2. GOTO

3. IF GOTO







Please refer the attached sample and config file:
http://websamples.syncfusion.com/samples/Edit/F70031/main.htm

Kindly take a look into the sample and modify the config file as per your language and let me know if this helps you.

Hi Bhuvana,

sorry, that didn't solve it either.

The lexems 1 and 2 (in that order) on their own work quite well - as long as there is no IF..GOTO statement.

Adding lexem 3 to config.xml doesn't make any difference to highlighting, but you can see at the collapse lines, that with added lexem 3 the IF..GOTO statement is wrongly ended with END_IF and in the other case (lexem 3 left away) the collapse line doesn't end at all.

Please add CollapseName attributes to the lexem tags and try to collapse the different blocks so you can see where the different lexems terminate. In addition please remove the stand-alone THEN lexem as THEN should be only highlighted within IF context.

I'm still quite at a loss.

Best Regards,
Steffen
