|
||||
|
||||
## How is this different from `vim.eunuch`?
|
||||
- Written 100% in lua.
|
||||
- Uses up-to-date nvim features like `vim.ui.input` or `vim.notify`. This means you can get nicer input fields via plugins like [dressing.nvim](https://github.com/stevearc/dressing.nvim), and nice confirmation notices with plugins like [nvim-notify](https://github.com/rcarriga/nvim-notify), if they are installed and setup.
|
||||
- Some minor improvements like automatically keeping the extensions when no extension is given.
|
||||
- Except for `trashFile` and `chmodx` only vim commands or lua os-modules are used to keep shell requirements to a minimum.
|
||||
|
||||
## Installation and Setup
|
||||
|
||||
```lua
|
||||
-- Packer
|
||||
use "chrisgrieser/nvim-ghengis"
|
||||
```
|
||||
|
||||
> __Note__
|
||||
> `ghengis` requires no `.setup()` function. Simply create keybindings for the commands you want to use.
|
||||
|
||||
```lua
|
||||
local ghengis = require("ghengis")
|
||||
local keymap = vim.keymap.set
|
||||
keymap("n", "<leader>yp", ghengis.copyFilepath)
|
||||
keymap("n", "<leader>yn", ghengis.copyFilename)
|
||||
keymap("n", "<leader>cx", ghengis.chmodx)
|
||||
keymap("n", "<leader>rf", ghengis.renameFile)
|
||||
keymap("n", "<leader>nf", ghengis.createNewFile)
|
||||
keymap("n", "<leader>yf", ghengis.duplicateFile)
|
||||
keymap("n", "<leader>df", ghengis.trashFile) -- requires macOS or Linux `mv` command
|
||||
keymap("x", "<leader>x", ghengis.moveSelectionToNewFile)
|
||||
```
|
||||
|
||||
## Available Commands
|
||||
- `ghengis.copyFilepath`: Copy the absolute file path. When `clipboard='unnamed[plus]`, copies to the `+` register, otherwise to `"`.
|
||||
- `ghengis.copyFilename`: Copy file name. When `clipboard='unnamed[plus]`, copies to the `+` register, otherwise to `"`.
|
||||
- `ghengis.chmodx`: Run `chmod +x` on the current file.
|
||||
- `ghengis.renameFile`: Rename the current file. If no extension is provided, will keep the current file extension.
|
||||
- `ghengis.createNewFile`: Create a new file. If no extension is provided, will keep use the extension of the current file.
|
||||
- `ghengis.duplicateFile`: Duplicate the current file. If no extension is provided, will keep the current file extension.
|
||||
- `ghengis.trashFile`: Move the current file to `$HOME/.Trash`. (Requires macOS or Linux, since is using `mv`.)
|
||||
- `ghengis.moveSelectionToNewFile`: Visual Mode Command. Prompts for a new file name and moves the current selection to that new file.
|
||||
|
||||
## Why that name?
|
||||
A tribute to [vim.eunuch](https://github.com/tpope/vim-eunuch) – as opposed to childless eunuchs, it is said that [Ghengis Khan has fathered thousands of children](https://allthatsinteresting.com/genghis-khan-children).
