QML Line Numbers

[bwiggs]

The QML frontend needs to support line numbers.

Sublime Text has a setting called line_numbers that is a boolean. See the Sublime Text Unofficial Documentation

See #164 for more context and discussions on the termbox frontend implementation.

Since the QML frontend treats each line as a separate item, it should be trivial to add in line numbers. The line number will just be the "index" (or index+1) of the delegate component created by the QML data model.

Is there any backend infrastructure that supports a Gutter? I'm thinking of ST plugins like GitGutter or SublimeLinter that add artifcats next to the line numbers.

Gutter icons are specified via view.AddRegions. This is how the syntax highlighting, spelling error-squiggly lines and other text metadata is specified too. It's the job of View.Transform and render.Transform to take all that data into account, usually with the help of Recipie.Transcribe too.

Though it looks like render.Flavour needs to be expanded with an icon field, and render.ViewRegionFlags should probably have a DRAW_ICON const added.

To make it easier for frontends, render.Transform should probably split all DRAW_ICON Flavours so that they are just DRAW_ICON Flavours in a zero sized region containing the start point of the region it's associated with.
