Re: [epsilon-dev] Re-building Epsilon grammar

[Dimitris Kolovos <dimitris.kolovos@xxxxxxxxxx>]

Hi Sina,

Have you followed the instructions in [1]?

- If you wish to modify the parsers (syntax) of Epsilon languages you
also need to clone the following repository next to Epsilon's Git
repository on your machine:
https://github.com/epsilonlabs/epsilon-antlr-dev.git
- To modify e.g. the EVL parser, you need to change Evl.g and/or
EvlParserRules.g. To re-generate the parser you need to run
build-evl-parser.xml as an Ant build.
- Since all Epsilon languages extend EOL, if you modify the EOL
parser, you'll then need to run build-all-eol-dependent-parsers.xml

Cheers,
Dimitris

However the ANT builds in the org.eclipse.epsilon.eol.parse package seem to not have been updated so they don’t work. Does anybody know how to update these ANT tasks or if there is an alternative way to generate the grammar?
