It seems ppgen can’t handle case-insensitive literals like ‘foo’. An example:

module languages/boo/Boo

imports Common

exports sorts Start A

context-free syntax

‘foo’ -> Start {cons(“Start”)}

Xy.generated.pp:

[

Start – _1,

Start.1:ci-lit – _1,

Start.1:ci-lit.1:“foo” – // error: *)

]

*) Multiple messages:

• Syntax error, ‘"’ not expected here

• Syntax error, ‘"’ not expected here

(Needs to be confirmed.)

(Based on the report by Otto Hausbacher in Spoofax/229.)
