TIL: How to Use Open Buffers When Debugging With Neovim’s DAP Plugin
I had an issue that whilst debugging my Golang tests in Neovim, the buffer I was focusing on would always change to the breakpoint. Even when the buffer was open and visible already, say I had the code with the breakpoint on the left buffer and the tests I was starting the debugger from on the right buffer.
You can see the example belows:
When I start the DAP debugger on the right hand side, by using it to debug the nearest tests, the buffer will change to the breakpointed line. However I want it to use the open buffer on the left because it is already open.
To do this we need to update our Neovim options:
vim.o.switchbuf = "useopen,uselast". This will now behave as we
uselast, here is the default value for this option. You can read more about by typing
That’s it! We can now debugger our code and keep the layout we have.
