Description

This is a plugin for Neovim to integrate with GDB. It's not stable yet, might have some bugs.

This plugin use the power of Neovim remote plugin and GDB's new-ui command. The new-ui command requires GDB version be 7.12+. This plugin will create a pseudo tty in Python client to connect to GDB's second interface.

Currently, it doesn't support Native Python executable in Windows system, which don't have os.openpty. You can use MingW Python or use Cygwin environment.

Features

  • keymap
  • line hint

Change keymap

let g:gdbmi_config = {
      \ 'key_until':             '<leader>du',
      \ 'key_advance':           '<leader>da',
      \ 'key_continue':          '<leader>dc',
      \ 'key_next':              '<leader>dn',
      \ 'key_step':              '<leader>ds',
      \ 'key_finish':            '<leader>df',
      \ 'key_reverse_continue':  '<leader>dC',
      \ 'key_reverse_next':      '<leader>dN',
      \ 'key_reverse_step':      '<leader>dS',
      \ 'key_reverse_finish':    '<leader>dF',
      \ 'key_breakpoint':        '<leader>db',
      \ 'key_frameup':           '<leader>dU',

      \ 'key_ui_scrollpagedown': '<pagedown>',
      \ 'key_ui_scrollpageup':   '<pageup>',
      \ }

or

let g:gdbmi_config_override = {
      \ 'key_continue':          '<F5>',
      \ }

To-do

  • fix bringing up gdb in different tabpage
  • add support for multi inferior
