0.7.0

What's Changed

Core

• Added support for domain sockets/named pipes. See :help dap-adapter for
  more information. An example of how it can be used:

local dap = require("dap")
dap.adapters.cmake = {
  type = "pipe",
  pipe = "${pipe}",
  executable = {
    command = "cmake",
    args = {"--debugger", "--debugger-pipe", "${pipe}"}
  }
}
dap.configurations.cmake = {
  {
    name = "Build",
    type = "cmake",
    request = "launch",
  }
}

• Adapters used with type=server and an executable will now receive a sigterm
  signal after the connection closes. This should ensure that there are no
  process leaks.
• Debug adapters are no longer terminated if there is a debug session active
  when exiting vim and the debug session has a configuration with
  request=attach. This avoids terminating processes that were started outside
  of neovim.
• If the debug adapter stops at a breakpoint, and the buffer containing the
  breakpoint is already open in a window, the window is now focused, unless the
  active window contains the REPL.
• If the debug adapter stops at a breakpoint, switchbuf is set to useopen
  or usetab, and the same buffer is open in multiple windows, the focused
  window is now prioritized and will change to the breakpoint location.
• Added some error handling improvements: Debug adapters exiting with a code
  not equal to 0 will return in a warning, and errors in configurations should
  now always propagate.
• Increased the priority of the signs, to make sure breakpoints are shown even
  if neovim diagnostics are present.
• Added a dap.ABORT value that can be used in configurations to abort the start
  of a session. This can be useful in combination with input prompts.

REPL

• If using the arrow up/down keys, the cursor is now moved to the end of the line
• Exposed a repl.execute function, to execute text as if entered in the REPL.
  This can be used in a mapping to evaluate a variable under the cursor, for
  example:

vim.keymap.set("n", "<leader>di", function()
  dap.repl.open()
  dap.repl.execute(vim.fn.expand("<cexpr>"))
end)

• The REPL history is now no longer cleared when starting a new session, but
  there is now a maximum size of 100 entries.
• The REPL should no longer loose focus on breakpoint stopped events.
• Fixed an issue in the completion omnifunc implementation that could lead to
  inserting duplicate words. For example -exec b some| completed to -exec b -exec b some_function() instead of -exec b some_function()
• Fixed some rendering issues that could lead to empty prompts interleaved in
  the output.
• Variables marked as "lazy" by the debug adapter are now automatically
  resolved when expanding children to avoid having to expand them twice to see
  the full value.

Widgets

• Added a listener option to the preview widget
• Fixed some issues that could cause floating windows to not close when
  selecting an item - e.g in the frames or threads views.
• Some more widgets will now show some information instead of being empty if
  there is no data available.
• The hover widget will now always evaluate an expression, instead of looking
  it up in the loaded variables.
• Variables marked as "lazy" by the debug adapter are now automatically
  resolved when expanding children to avoid having to expand them twice to see
  the full value.
• The winopts of widgets now accept a title option.
• Calling .toggle() on a widget multiple times should no longer append new
  text each time, but replace the contents.
