Hello Michael,

I want to define a range (start-end), which detects such a header section:

*"----------------------------------------------------------------------
*"*"Lokale Schnittstelle:
*" IMPORTING
*" VALUE(QUERY_TABLE) TYPE DD02L-TABNAME
*" VALUE(ROWCOUNT) TYPE SOID-ACCNT DEFAULT 0
*" EXPORTING
*" VALUE(ROWSREAD) TYPE SOID-ACCNT
*" VALUE(DATAPATH) TYPE RFCPUT-PATH
*" VALUE(RECSIZE) TYPE SOID-ACCNT
*" TABLES
*" FIELDS STRUCTURE RFC_DB_FLD
*" OPTIONS STRUCTURE RFC_DB_OPT
*" ORDERBY STRUCTURE RFC_DB_FLD
*" EXCEPTIONS
*" TABLE_NOT_AVAILABLE
*" TABLE_WITHOUT_DATA
*" FIELD_NOT_VALID
*" NOT_AUTHORIZED
*" FILE_ERROR
*"
*"----------------------------------------------------------------------

Is this possible? (I fail, because the start-rule is the same as the end-rule *"-------------)

I found a solution:

Defining:

1.Token "HeaderLine" with regex \*"-+

2.Range End "Header End" with condition "HeaderLine" and Parent Block "Header" and cancel rules.

3.Range Start "Header" with Range End "Header End" and condition "HeaderLine"

Is this correct?

Wow, impressive. Being able to create complex or just complete syntax settings for different languages is pretty much the final frontier for me with this control - I just have no really good idea where to start and am too scared to look through the code to "work it out".

I'd love to have 4-5 tutorials based on creating the lexer / syntax analyser for a relatively complex language, from start to finish.

Yes, this solution is correct.

P.S. Lexer design tutorial will be in new documentation.

Michael.
