Matching seems broken

[tivac]

Just installed this into vscode@0.10.10 and I'm unable to get live OR manual matching to work.

Settings:

"trailing-spaces.logLevel": "error",
"trailing-spaces.includeEmptyLines": false,
"trailing-spaces.includeCurrentLine": false,
"trailing-spaces.regexp": "[ \t]+",
"trailing-spaces.liveMatching": true,
"trailing-spaces.modifiedLinesOnly": false,
"trailing-spaces.syntaxIgnore": [],
"trailing-spaces.trimOnSave": true

but even after a restart of VSCode opening a file like this shows nothing:

asdfa   

d    

ddddd

If I attempt to manually trigger matching I get this:

Running the contributed command:'trailing-spaces.highlightTrailingSpaces' failed.

I'm getting a relevant-seeming error in the debugging console:

Invalid regular expression: /(?<=S)[    ]+$$/: Invalid group: SyntaxError: Invalid regular expression: /(?<=S)[     ]+$$/: Invalid group

Seems like an issue with the handling of trailing-spaces.includeEmptyLines property. You can set it to true for the time being. Will fix in the next version tomorrow.

I have published a new version of the extension (v0.2.0) to the marketplace. Could you please update and confirm if this is fixed?
