vim-delve
This is a Neovim and Vim plugin for debugging Go applications using Delve. The project works a lot nicer on Neovim with the built-in terminal, so that's what we recommend. But it is decent to work with on Vim if you have Shougo/vimshell.vim installed.
If you like this project, please star it. If you feel even more generous, please follow @sebdah on Twitter!
Feature highlights
- Go syntax highlighting of debug output (only Neovim)
- Supports both breakpoints and tracepoints
- Run the Delve debugger in a split view along side your code
- Launches a Delve CLI, so all commands are supported in there
- Leverages the Neovim terminal (only on Neovim)
- Supports
mainas well as and non-mainpackages - Supports vimux optionally
Requirements
For Neovim and Vim 8, you really only need Delve to get started.
If you wish to use the vimux support, you'd need to have this plugin as well:
Requirements for Vim 7 and earlier
If you are on Vim versions older than 8, you'll also need the following two packages:
Installation
Using vim-plug, add the following to your init.vim if you're on Neovim or
.vimrc, if you're on vim:
Plug 'sebdah/vim-delve'
Then reload neovim and run PlugInstall.
