nvim init with cursor synchronisation across windows

readme.md

nvim source

for global use of nvim

append path\to\nvim\bin to PATH env variable
change XDG_CONFIG_HOME system env variable to value path\to\ config then is at \path\to\nvim\init.vim
set MASTERTXT system env variable to value path\to\master.txt required for vim.init cursor sync
set ALTTXT system env variable to value path\to\alt.txt required for vim.init cursor sync

for git.py integration

privates.py with gitpypath var is required
set privates env variable to value path\to\private\

others tricks

nvim -u /path/to/init.vim start nvim with pointing to init file

init.vim
