Not able to parse some real awk scripts

[xonixx]

I'm not sure how compatible this project aims to be. Out of curiosity I tried it on a couple of my projects: makesure and gron.awk:

$ java -jar soft/jawk-3.0.01-standalone.jar -f makesure.awk
ParserException: Expecting 277 _COLON_. Found: 264 _STRING_ ("@") (makesure.awk:233)

$ java -jar soft/jawk-3.0.01-standalone.jar -f gron.awk
ParserException: Expecting an ID. Got (258): 
     (gron.awk:82)

Both of the scripts are compatible with gawk, bwk, mawk, busybox awk & goawk.

Hi, sorry we didn't notice the issue you registered. Let us look into this!

Hi @xonixx

We've just released version 3.1.00 of Jawk which fixes the operator precedence of the parser. It now strictly follows gawk.

gron.awk now kind of works... except we're still encountering issues when parsing JSON objects (arrays seem to be fine). Could you please pinpoint what is going on and what is actually failing?

echo [1, 2, 3] | java -jar target/jawk-3.1.00-standalone.jar -f src/test/resources/xonixx/gron.awk
json=[]
json[0]=1
json[1]=2
json[2]=3

But...

echo {"a": 1} | java -jar target/jawk-3.1.00-standalone.jar -f src/test/res
ources/xonixx/gron.awk
Can't parse JSON at pos 2: a: 1}

makesure.awk still doesn't work because we're missing a few gawk-specific funtions (non-POSIX), like gettimeofday():

java -jar target/jawk-3.1.00-standalone.jar -f src/test/resources/xonixx/makesure.awk
SemanticException: function org.sentrysoftware.jawk.frontend.AwkParser$FunctionProxy@593634ad (gettimeofday) not defined (src/test/resources/xonixx/makesure.awk:717)

Thank you @bertysentry, excellent work! Sure, I’ll check when I have time.

[xonixx]

Regarding the missing function gettimeofday(). Yeah, this is expected. But you can still check this one by adding one more -f flag and referencing https://github.com/xonixx/makesure/blob/main/mawk_ext.awk with this function stub.

So here is one bug I've triaged so far:

$ java -jar soft/jawk-3.1.00-standalone.jar 'BEGIN { print !xxx }'
0
$ awk 'BEGIN { print !xxx }'
1

@xonixx Please see #91 ;-)

One other bug please:

$ java -jar soft/jawk-3.1.02-standalone.jar 'BEGIN { exit 17 }'; echo $?
0
$ awk 'BEGIN { exit 17 }'; echo $?
17

Thank you @xonixx! See #94
