Vimview is my new pet project. The goal was to follow source code in vim, when using gdb. I wanted it to be done without heavy vim scripting. So I wrote a single file gdb plugin in Python. It makes vim to follow gdb frame (by opening files and moving cursor to the corresponding lines) while vim and gdb are running in separate terminals.
Vim has the ability to be controlled by RPC, gdb can be scripted in Python. That’s all what we need. Plugin and instruction are on my github.
