#INSTALL QUERY pageRank

Has anyone got syntax hiliting to work in Visual Studio Code?

@danmccreary Sample of GSQL syntax highlighting of the query above :point_up_2:

Here is a screenshot of the “EXTENSION”:

Looks awesome! I just installed it and it worked great!

:slight_smile: Now, code formatter (beautifier) would be great.
