Summary of installs

CAUTION: install on home laptop (wwtlaptop) has issues; nvim seems to run, but installation of plugins was challenging.

nvim (nvim-qt.exe) runs, but has issues. Don't depend on it for serious work (e.g. syntax checking) nvim happens to run on work laptop, I don't know why it does.

code: at the bottom of NVIM v0.6.0 (both are from tar/zip, not from packages)

    cygwin:  nvim-win64.zip
    linux:   nvim-linux64.tar.gz

exe locs:

    piedmont:    /home/wendell/nvim/local/nvim-linux64/bin/nvim
    home lap:    alias nvim="SHELL=/cygwin64/bin/bash ~/pkgs/Neovim/bin/nvim-qt.exe"
    opalstack:   alias nvim='/home/wendell/pkgs/nvim-linux64/bin/nvim'

    work lap:    alias nvim="~/pkgs/Neovim/bin/nvim.exe"
    work svr:    ???

init locs:

    piedmont:  ~/.config/nvim/init.vim
    home lap:    /cygdrive/c/Users/wendell/AppData/Local/nvim

    work lap:  C:\\Users\\Public\\cygwin\\home\\WENDEL~1\\nvim_config\\

configuration check:

    nvim +checkhealth
    nvim
        :python3 print('yipee!')

autoload:

    adjacent to init.vim?

swap files:

    ???

environ vars:

    cygwin home (note: uses linux-style config location):
        export XDG_CONFIG_HOME="C:\\cygwin64\\home\\wendell\\.config\\"
        export   XDG_DATA_HOME="C:\\cygwin64\\home\\wendell\\.config\\"
        alias nvim=<see above>

    cygwin work (note: uses windows-style config location):
        export XDG_CONFIG_HOME="C:\\Users\\Public\\cygwin\\home\\WENDEL~1\\nvim_config\\"
        export   XDG_DATA_HOME="C:\\Users\\Public\\cygwin\\home\\WENDEL~1\\nvim_config\\"
        alias nvim="~/pkgs/Neovim/bin/nvim.exe"
    linux:
        nothing in particular

plugins & config:

    syntax checking: ale [flake8]
    color scheme:    gruvbox

python pkgs:

    pip3 install neovim
    pip3 install pynvim          # already installed???
    pip3 install pylint
    pip3 install flake8          # syntax checker
    pip3 install python3-neovim  # not sure

status:

installations completed:

    piedmont:   done
    home lap:   had issues, but -qt version runs somewhat
    opalstack:  done

    work lap:   same as home lap
    work svr:   done

TODO:

And finally, after 3 or 4 days of flailing:

Cygwin install

1) executable

d/l nvim-win64.zip from <???> and unzip

this seems to help:

    chmod a+rx *.dll
    find . -name "*.dll" -exec chmod a+x {} \; -print

and setup .bashrc:

    export XDG_CONFIG_HOME="C:\\Users\\Public\\cygwin\\home\\WENDEL~1\\nvim_config\\"
    export   XDG_DATA_HOME="C:\\Users\\Public\\cygwin\\home\\WENDEL~1\\nvim_config\\"
    alias nvim="~/pkgs/Neovim/bin/nvim.exe"

2) using Cygwin's setup.exe, install this:

    python3.8-devel

3) install python's package:

    05:12:34 ~ $ pip3.8 install neovim

    Collecting neovim
      Using cached neovim-0.3.1.tar.gz (804 bytes)
      Preparing metadata (setup.py) ... done

4) nvim +checkhealth

finally found a useful parameter!!!:

    nvim +checkhealth

Examine that output, and adjust accordingly...

put this in the init.vim:

    let g:python3_host_prog="C:/Users/Public/cygwin/bin/python3.8"

and finally, +checkhealth looks mostly good:

    05:30:35 ~ $ nvim +checkhealth

    nvim: health#nvim#check
    ========================================================================
    ## Configuration
      - OK: no issues found

    ## Performance
      - OK: Build type: RelWithDebInfo

    ## Remote Plugins
      - OK: Up to date

    ## terminal
      - ERROR: command failed: infocmp -L

      - INFO: $TERM_PROGRAM='mintty'

have no idea about the terminal error, or what to do about it

5) test python

    nvim
    :python3 print('yipee!')

and the output shows up in the command/status line!

6) install (the first) plugin

    nvim
    :PlugInstall

and the split-screen shows up, and it appears that the plugin installs(!!!).

Cygwin on home laptop:

nvim-qt.exe +checkhealth opens a window, but then freezes

nvim.exe +checkhealth freezes

    ERROR: Failed to run healthcheck for "provider" plugin.  Exception:
    ...
    Vim(let):E903: Process failed to start: no such file or directory: "/bin/bash"

TRY THIS:

    export XDG_CONFIG_HOME="C:\\Users\\wendell\\AppData\\Local\\"
    export XDG_DATA_HOME="C:\\Users\\wendell\\AppData\\Local\\"
    alias nvim="~/pkgs/Neovim/bin/nvim.exe"

PROBLEM is discussed here: Neovim :checkhealth problems

SOLUTION:

    export SHELL=/cygwin64/bin/bash

(but just for the -qt version, terminal one still freezes)

HOWEVER, still issues abound...

    cd /
    mkdir cygwin64
    cd cygwin64
    ln -s /bin bin

Linux

    > sudo yum install neovim python3-neovim

using:

    ~/.config/nvim/init.vim

    stdpath('data') == ~/.local/share/nvim/

and:

    cd ~/.local/share/nvim
    mkdir vimplug

and:

> pip3.9 install neovim

Manually:

    cd .config/nvim
    mkdir autoload
    cd autoload
    vim plug.vim
    <contents of https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim>

CRAP:

    > nvim --version
    NVIM v0.3.8
    Build type: RelWithDebInfo
    LuaJIT 2.1.0-beta3

Nope, couldn't find and rpm that worked, so just d/l this and extract as necessary:

nvim-linux64.tar.gz

putty notes

To use with ssh via putty:

1) use putty 0.76 release

2) check all boxes on putty color tab:

3) export TERM=xterm-256color

dec 30

Am starting over again with a new .config/nvim/init.vim based on the youtube video from Red Eye Coder Club.

    config file:  ~/.config/nvim/init.vim
    plugin dir:   plug#begin(stdpath('data') . 'vimplug')

I think the plugin dir is::

    ~/.local/share/nvim/vimplug
