I am a Code Editor guy, and I am a Terminal Guy. I try all of the Editors from SublimeText VSCode to PyCharm and I keep coming back to Vim/Neovim.
Because I work on AI/ML there's no way to not develop in Python and not be confronted with people demo'ing code with Jupyter Notebooks. I confess that is really cool.
So, I went on the journey to figure out to solve this missing feature on Neovim.
So, for a start, I will show how to do it with LazyVim as it's package manager could not be easier to get stuff started for someone willing to try Neovim for a spin.
TL;DR: see video https://www.youtube.com/watch?v=8xP1eZ7E0h0
Neovim Installation
brew install neovim@0.9.0
Other Requirements
- Git
- Python
If you don't have it yet install them (or just stop here 😁):
brew install git
brew install python@3.11
Install Lazyim
Backup Old Config
If you already have another installation, do some backups:
# required
mv ~/.config/nvim ~/.config/nvim.bak
# optional but recommended
mv ~/.local/share/nvim ~/.local/share/nvim.bak
mv ~/.local/state/nvim ~/.local/state/nvim.bak
mv ~/.cache/nvim ~/.cache/nvim.bak
Download the lazyvim starter, and don't be surprised how *fast & furious" the installation is:
git clone https://github.com/LazyVim/starter ~/.config/nvim
Now, take the neovim to a spin, hold your seat and run:
nvim
Install Plugin to Run Code
After a successful install of Lazyvim, exit and let's add a plugin:
cd ~/.config/nvim
nvim .
Create a file ('a' command on the File Browser) on folder lua/plugins/code-runner.lua
return {
"hkupty/iron.nvim",
config = function(plugins, opts)
local iron = require("iron.core")
iron.setup({
config = {
-- Whether a repl should be discarded or not
scratch_repl = true,
-- Your repl definitions come here
repl_definition = {
python = {
-- Can be a table or a function that
-- returns a table (see below)
command = { "python" },
},
},
-- How the repl window will be displayed
-- See below for more information
repl_open_cmd = require("iron.view").right(60),
},
-- Iron doesn't set keymaps by default anymore.
-- You can set them here or manually add keymaps to the functions in iron.core
keymaps = {
send_motion = "<space>rc",
visual_send = "<space>rc",
send_file = "<space>rf",
send_line = "<space>rl",
send_mark = "<space>rm",
mark_motion = "<space>rmc",
mark_visual = "<space>rmc",
remove_mark = "<space>rmd",
cr = "<space>r<cr>",
interrupt = "<space>r<space>",
exit = "<space>rq",
clear = "<space>rx",
},
-- If the highlight is on, you can change how it looks
-- For the available options, check nvim_set_hl
highlight = {
italic = true,
},
ignore_blank_lines = true, -- ignore blank lines when sending visual select lines
})
-- iron also has a list of commands, see :h iron-commands for all available commands
vim.keymap.set("n", "<space>rs", "<cmd>IronRepl<cr>")
vim.keymap.set("n", "<space>rr", "<cmd>IronRestart<cr>")
vim.keymap.set("n", "<space>rF", "<cmd>IronFocus<cr>")
vim.keymap.set("n", "<space>rh", "<cmd>IronHide<cr>")
end,
}
Save a exit the file <space>qq
Test Code Runner
Open a python file test.py:
name = "AIOPS Again"
print(f"Hello, {name}")
name = "Another AIOPS"
print(f"Hello, {name}")
Type <space>r and ENTER and you should have the code execution window on the right side:
If you to execute the code you have several options:
-
Execute Line by Line
<space>rl -
Execute Selected Lines
<space>rc -
Execute the all file
<space>rf
Try to execute a selection of line, by selecting some lines:
And them send the code to the runner:
In reality this plugin can run whatever you want:
