Usage

Sticky Scroll

This is the main feature of the plugin. This adds a Phantom at the top your code with the truncated context stack of the current function you are in.

Basically, if you're inside a big class or nested functions, it keeps track of them and display those class and function definition that are out of your viewport at the top.

This is language independent and works as long as the language is supported by Sublime Text.

Note: context depth is tracked through indentation level. This won't work if your code isn't indented properly.

About performances and jitteriness

There is no way in the Sublime API to react to viewport change. This means that this plugin requires a periodic task to work.

Impact on performances should be minimal but this is important to keep in mind.

The lack of proper UI feature and the use of phantoms also creates some jittering effect on the text buffer. I tried to reduce it at a maximum with some stabilization features but it can only go so far.

For all of this reasons, if you're only interested by the Popup feature or want to completely disable the background periodic task when not needing the plugin, you can set sticky_lines_auto_follow to false or type StickyLines: Toggle Auto Follow in the command palette (sticky_lines_toggle_auto_follow command).

Usage

The default behavior is to always be activated on every view depending on sticky_lines_enabled_globally setting. It's default is true.

You can change this by going through the settings or using the command palette with StickyLines: Toggle Globally (sticky_lines_toggle_globally command).

You can override this behavior by toggling this on specific views with StickyLines: Toggle on View (sticky_lines_toggle_on_view command).

Popup

This plugin also provides a nice popup that shows those same info but on a popup under your cursor. It has to be called manually with StickyLines: Show Popup (sticky_lines_show_popup command).

Note: this also relies on code being indented properly.
