  • support for SQL and other languages features in string literals

• Navigation:

  • builtin documentation display
  • jump to definition or usage / implementation

@rakyll can you please assign this to me? Thank you.

[dlsniper]

@rakyll I've updated the issue, what are the next steps?

[rakyll]

@dlsniper, thanks!

Can we also have some screencast gifs that demonstrates some features? Screencasts need to be 1280x640 gifs. Pick top 3-5 feature and record a screencast gif for each please.

Once we have it all, I will move them to a golang.org page and will CC you on the CL.

I can record some GIFs. Just to confirm, if we want to have them in Retina, does it mean we'll need their actual size to be twice bigger, i.g. 2560 x 1280?

[rakyll]

@cheptsov I don't think we will maintain retina sizes for all screencast gifts, so downsizing them to 1280x640 would be perfect if you are recording from a Retina display.

[cheptsov]

@rakyll will this one work?

[rakyll]

@cheptsov, yes, it looks great!

[cheptsov]

There are five GIFs prepared:

Smart completion Create function quick-fix Extract function & rename refactorings Go to class & Go to implementations Implement interface quick-fix

CL https://golang.org/cl/45772 mentions this issue.
