Control Bar

The control bar can be used to control a session with clickable "buttons".

It is disabled by default. It can be enabled by setting winbar.controls.enable.

Custom Buttons

nvim-dap-view provides some default buttons for the control bar, but you can also add your own. To do that, you can use the winbar.controls.custom_buttons table to declare your new button, and then add it at the position you want in the winbar.controls.buttons list.

A custom button has 2 methods:

  1. render, returning a string used to display the button (typically an emoji or a NerdFont glyph wrapped in a highlight group). Receives the focused session as a parameter.
  2. action, a function that will be executed when the button is clicked. The function receives 3 arguments:
    • clicks, the number of clicks
    • button, the button clicked (l, r, m)
    • modifiers, a list with the modifiers pressed (c for control, s for shift, a for alt and m for meta)

See the @ N section in :help statusline for the complete specifications of a click handler.

Example

An example adding 2 buttons:

  • fun: the most basic button possible, just prints "🎊" when clicked
  • term_restart: a hybrid button that acts as a stop or restart button. If the button is triggered by anything else than a single left click (middle click, right click, double click or click with a modifier), it will disconnect the session instead of stopping.
