Hello everyone,

My name is Belal. This is my first post in GF group. I am an Arabic second language educator and native speaker,  and I am looking into GF as a option for creating interactive Arabic teaching and learning resources for the web. 

I have been experimenting with GF - and so far so good. It looks very promising for the specific application domain that I have in mind. 

When I tried creating identifiers with only Arabic characters, I keep getting a "lexical error" when compiling the grammar. When changing the identifier to something in English, the error goes away and it compiles fine. 

My .gf files are in UTF-8 encoding (I manually checked this) and I added the "-coding" pragma to the top of the file containing the Arabic identifier:

--# -coding=utf8

 as per this link:


Is there anything I missed? Please advise. Thanks!

- Belal

Hi Belal,

without seeing your code, my guess is that you need to put the fun and lin names inside single quotes ''. You can see examples e.g. in the Estonian dictionary module https://github.com/GrammaticalFramework/gf-rgl/blob/master/src/estonian/DictEst.gf 
lin
aabitsatarkus_N = mkN "aabitsa" (mkN "tarkus" "tarkuse" "tarkust" "tarkusesse" "tarkuste" "tarkusi") ;
'aabitsatõde_N' = mkN "aabitsa" (mkN "tõde" "tõe" "tõde" "tõesse" "tõdede" "tõdesid") ;
The first identifier has only ASCII characters so it's written without quotes, but the second one has õ, so it's wrapped in single quotes. So it should work to just define identifiers like  'خدم_V'.

Cheers,
Inari
