venkat.vim is an nvim plugin to execute on-save source files and prints back the result in a floating window. Release the window with ESC.
This plugin is inspired by Venkat Subramanian usage of TextMate in his presentations and by TJ with his excellent autocmd tutorial.
By default, whenever saving a main.go, main.py, main.rs, main.java, neovim will compile and run, and preview
the result in a floating window.
Open for example /tmp/main.go, save it, :w or hit leader + ru ("ru" for run), and enjoy a quick output in a new floating window!
Using packer:
use({
'rgolangh/venkat.nvim',
config = function()
require("venkat").setup({})
end,
})
Using Lazy:
return {
{ "rgolangh/venkat.nvim", lazy = false },
}Here's the default configuration:
-- onSave will execute the buffer, according to the pattern on save (:w)
-- set to false to completely disable this.
onSave = true,
-- default key mapping to execute the buffer
mapping.execute = "<leader>ru",
languages = {
go = { cmdline = "go run %s", pattern = "main.go" },
java = { cmdline = "java %s", pattern = "main.java" },
python = { cmdline = "python %s", pattern = "main.py" },
-- requires Cargo.toml in the target directory or its parent.
rust = { cmdline = "cargo -Zscript %s", pattern = "main.rs" },
zig = { cmdline = "zig run -lc -lraylib %s", pattern = "main.zig" },
c = { cmdline = "zig run -lc %s", pattern = "main.c" },
js = { cmdline = "node %s", pattern = "main.js" },
lua = { cmdline = "luajit %s", pattern = "main.lua" },
}
The use of pattern here adheres to nvim's file pattern usage. Because executing all the file on save is not usually what you want while developing, a pattern can make this more handy. Consider these examples:
-- all python files under demos a relative demos directory:
pattern = "*/demos/*.py"
-- all python files under demos a relative demos directory and any main.py:
pattern = "demos/*.py,main.py"For more info see :help file-pattern
If you want to customize the configuration, expand the config in init.lua or set this $HOME/.config/nvim/after/plugin/venkat.lua :
require('venkat').setup({
languages = {
go = { cmdline = "go run %s", pattern = "demos/*.go,main.go" },
java = { cmdline = "java %s", pattern = "demos/*.java,Main.java" },
python = { cmdline = "python %s", pattern = "demos/*.py,main.py" },
rust = { cmdline = "cargo -Zscript %s", pattern = "main.rs" },
zig = { cmdline = "zig run %s", pattern = "main.zig" },
c = { cmdline = "zig run -lc %s", pattern = "main.c" },
}})
