Sure works.

Regex

'((XXX Logical Channel) ([0-9])) on (((Upstream)|(Downstream)) ([0-9])) on ((chassis) ([0-9])), ((slot) ([0-9])), ((mac) ([0-9]))' asRegex

But in PP, things were more comple and there were a lot of them, so:

line

^ temperatureStatusDescrEntry token asParser

/ temperatureStatusValueEntry token asParser

/ temperatureThresholdEntry token asParser

/ temperatureLastShutdownEntry token asParser

/ temperatureStateEntry token asParser

and things like

temperatureStatusDescrEntry ^ temperatureStatusDescrOidPrefix, oidIndex, space, equals, space, stringType, space, displayStringValue.

made my day much easier.

Especially when I had all the tokens I needed:

gauge32Type ^'Gauge32:' asParser flatten ==> [:str | #gauge32].

��Not sure it would have been as flexible with a SmaCC (I am not familiar with SmaCC but used Lex/Yacc|Bison in another life).
