Research direction

Start with the krun input path and compare it with the krun -cPGM='bar()' path, using the provided test.k definition and in file. Run kompile test.k, then both krun commands to reproduce the parser error. Done means file input produces the same result as the -cPGM form, including the shown output.

What component is the issue in?

Front-End

Which command
  • kompile

What K Version?

v5.5.97-0-gb45441ceea

Operating System

endmodule

module TEST
  imports TEST-SYNTAX

Expected Results

The expected result is the same as if we execute krun -cPGM='bar()':

<k>
  bar ( ) ~> .
</k>

However, we have a parser error:

[Error] Inner Parser: Scanner error: unexpected character sequence 'b'.
	Source(/Users/robertorosmaninho/rv/k-training/issue-example/./in)
	Location(1,1,1,2)
	1 |	bar()
	  .	^
[Error] kparse:

kore --definition ./ex1-kompiled in
[Error] krun: kparse --definition ./ex1-kompiled in
