Also consider https://spacevim.org/ (inspired by Spacemacs)
or, avoid spacemacs & spacevim, and just install evil-leader,
evil-surround, and evil-matchit. Emacs starts up faster in this case too.
Recommendation to a former Vimmer who wants to try Emacs to avoid Spacemacs IMO is irrational. Spacemacs and Doom-emacs are the best things to try. Spacemacs is well documented, community supported and extremely popular among former Vimmers. Trying to learn and configure Emacs from scratch usually does the opposite effect - an overwhelmed person gives up and runs back to the comfort of the familiar tool.
I guess I made a good choice since emacs is able to integrate an x manager (lol).
The issue for me is my tmux leader is Ctrl-f and my vim Ctrl-p uses ctrl-p.. ctrl-d and ctrl-u are used in vim for page up and down. And some other nice Ctrlkeys are taken by vim as well. I will need to carry these key bindings into emacs evil mode...
So Really running out of good leader keys I can use !
I started on evil-mode only. Heard about space macs but I wasn’t sure how well it could work with emacs ide-packages such as SLIME for lisp (and I will want to find emacs ides for Java, Js, Python, C, Cpp, ruby, Ocaml - any suggestions here much appreciated as well)
