My own version of Dev Environment Files

This is my own version of Josean's very excellent LazyVim configuration.

He has many excellent videos that explain what these are and how they work.

Build NeoVIM

Use decent gcc and cmake:

    gcc 8.x
    cmake-3.28.1

Compile NeoVIM from sources, using the guidelines from here.

    git clone https://github.com/neovim/neovim
    cd neovim

    make CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX=$HOME/neovim -DCMAKE_BUILD_TYPE=RelWithDebInfo"
    make install
    export PATH="$HOME/neovim/bin:$PATH"

Before starting NeoVIM

Before starting your new nvim the first time, make sure all associated/support tools are installed and in your PATH:

   gcc   --version    # Red Hat 8.3.1-3
   cmake --version    # cmake version 3.22.2

   nvim  --version    # NVIM v0.10.0-dev-2255+g4c9119461
   git   --version    # 2.29
   node  --version    # Node version must be >= 14
   npm   --version    # npm version must be >= 7

   cargo --version    # cargo 1.74.1
   rg    --version    # ripgrep 13.0.0
   fd    --version    # fd 8.6.0

   pylint  --version  # pylint 2.12.2
   pyright --version  # pyright 1.1.347

These may require:

    export PATH=/opt/rh/devtoolset-8/root/usr/bin:$PATH
    export PATH=$HOME/pkgs/git-2.29.3:$PATH

The rest of this section describes the misc procedures used to ensure that recent versions of those tools are installed.

Install workable versions of node, npm, etc.

node, npm:

    wget https://nodejs.org/dist/v16.20.2/node-v16.20.2-linux-x64.tar.gz
    tar zxvf node-v16.20.2-linux-x64.tar.gz

These may require:

    export PATH=$HOME/pkgs/node-v16.20.2-linux-x64/bin:$PATH

cargo:

    curl https://sh.rustup.rs -sSf | sh

    info: downloading installer
    Cannot execute /tmp/tmp.RzCLQH8sSn/rustup-init (likely because of mounting /tmp as noexec).
    $ mkdir cargo
    $ cd cargo
    $ cp /tmp/tmp.RzCLQH8sSn/rustup-init .
    $ ./rustup-init
    Welcome to Rust!
    ...
    info: default toolchain set to 'stable-x86_64-unknown-linux-gnu'
    stable-x86_64-unknown-linux-gnu installed - rustc 1.75.0 (82e1608df 2023-12-21)

    Rust is installed now. Great!
    To get started you may need to restart your current shell.
    This would reload your PATH environment variable to include
    Cargo's bin directory ($HOME/.cargo/bin).

    To configure your current shell, run:
    source "$HOME/.cargo/env"

ripgrep:

from: BurntSushi/ripgrep

    git clone https://github.com/BurntSushi/ripgrep
    cd ripgrep
    cargo build --release
    cp target/release/rg ~/local/bin

and then:

    rg --version
    ripgrep 14.1.0 (rev 9b42af96f0)

fd (find files):

from: sharkdb/fd (do not install the yum verion)

    cargo install fd-find

or possibly:

    cd ~/pkgs/fd
    mkdir tmp
    CARGO_TARGET_DIR=~/pkgs/fd/tmp cargo install fd-find

and then:

    fd --version
    fd 9.0.0

these are apparently needed also:

    npm install -g neovim
    pip3 install neovim pylint pyright

Starting NeoVIM

if you already had nvim running (or attempted), move all of those configurations aside:

    cd ~/.config       ; mv nvim nvim_feb2
    cd ~/.local/share  ; mv nvim nvim_feb2
    cd ~/.local/state  ; mv nvim nvim_feb2
    cd ~/.cache        ; mv nvim nvim_feb2

Install config

After viewing Josean's videos listed in his My Dev Environment Files page, I finally worked out a set of config files that actually work! Note that this config is based on LazyVim, i.e., it uses the LazyVim plugin manager.

I started with that config, and then made some of my own changes to it:

• I use other languages, so these LSPs were added:
  • VueJS, bash, awk, json
• I don't want source code automatically reformatted, so:
  • black, flake8, isort were explicitly commented out (in several places)

Now, do something like this:

    cd lazyvim/
    git clone git@github.com:wendellwt/dev-environment-files.git
    cd dev-environment-files/.config
    cp -R nvim ~/.config/

If it all seems in place, start nvim and watch it install everything:

    nvim

    :checkhealth

Yipee!!!, right?

NerdFont on windows

refs: Beautify your Windows Terminal using Nerd Fonts and Oh-My-Posh

which says to:

  mkdir fira
  cd fira/
  wget https://github.com/ryanoasis/nerd-fonts/releases/download/v3.0.1/FiraCode.zip  unzip FiraCode.zip

and then, in File Explorer:

    highlight all .ttf files
      -> Install

then, in PuTTY:

  -> Load
  -> Appearance
    FiraCode Nerd Font Mono

However, take a look at these, they may be better:

• Martian
• Meslo
• SauceCodePro
• MonaSpace
