This PR is an attempt to add a
#replace! @capture "regexp(.*)" "rep$1" predicate that can be used to filter content. This is useful for things like extracting injection languages from shebangs or heredocs, and will provide an official equivalent of the
#gsub!` function supported by NeoVim.However, I am not sure what the best way to do this is. It seems like this more or less requires instrumenting a
Node
in some way thatutf8_text
/utf_16
text know to return data from a buffer rather than the input. I am going to try adding something toNode
to allow this, but would like to know if there are other suggestions.
