Autocompletion and syntax highlighting in Intellij IDEA

[06needhamt]

In order for me to implement auto-completion and syntax highlighting i require a JFlex grammar file for Morganey as detailed here. I see you already have a BNF definition for Morganey in README, so i tried to use this tool with these command line options --java --jflex to generate a JFlex grammar from it, However it fails with a lexer error when I Input the BNF. Having a JFlex grammar will allow me to continue implementing autocomplete and syntax highlighting .

Many Thanks

However it fails with a lexer error when I Input the BNF

Could you please attach the log of the tool including the error message?

This is the only output i get

C:\Users\thoma\Desktop>bnfc --java --jflex test.bnf > bnfc.log
bnfc: user error (syntax error at line 1 due to lexer error)

@06needhamt please attach the bnfc.log and test.bnf files.

@06needhamt better use Gist next time!

[06needhamt]

@06needhamt and your bnfc.log looks suspicious — as if you taken your command line input and not the log file itself.

(I'm still downloading bnfc to verify)

[06needhamt]

@ForNeVeR that's all the log is the routed command line output

[ForNeVeR]

In my case bnfc.log is empty. bnfc: user error (syntax error at line 1 due to lexer error) is really the only output.

First of all, the BNF in the README is not a correct BNF. It was created just for the user's information. The first step is gonna be making the BNF in the README a correct BNF specification of the language syntax.

The issue has been split.

Pieces

• [x] #248 Make BNF in the README correct so it can be successfully converted by bnfc utility
• [x] #251 Flex grammar for Morganey syntax

[rexim]

Changed the title of the ticket, because it looked like it's a duplicate of #251
