I tried Conque GDB which is written in Python. But it was so slow. This video shows how it works with Vim. https://www.youtube.com/watch?v=ZcSjaYSoqnc But on my Linux PC, the Conque gdb plugin view would refresh every time I typed a letter.
And I tried vim-vebugger. https://github.com/idanarye/vim-vebugger But it didn't work in Vim, maybe it would work in Gvim (haven't tested though)
Do you have some good suggestions?
