[jira] [Commented] (GROOVY-7765) Dollar Slashy String in assert not working left hand side

["Paul King (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-7765?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15169914#comment-15169914 ] 

Paul King commented on GROOVY-7765:
-----------------------------------

This is a limitation within the current grammmar for both the slashy and dollar slashy strings. It isn't really to do with 'assert' per se. These also won't work:
{code}
assert /aaa/ == 'aaa'
println /aaa/
println $/aaa/$
{code}
brackets are your friends here:
{code}
assert ($/aaa/$ == 'aaa')
println ($/aaa/$)
{code}
We aren't likely to fix this in the current grammar. It is a good thing to look at when doing our antlr4 grammar (currently being spiked).
