## Notice
|
||||
|
||||
This is under development, do not try to use it right now. The best you could do is wait or give me tips to work better with lua.
|
||||
|
||||
I am working on this plugin to learn lua, learn neovim api and create a **simple** file explorer with features i need.
|
||||
|
||||
I really don't like any of the vim trees, they are all too complicated for their purpose. I do have my shell to do most commands.
|
||||
- This plugin is under development, it does not yet have all basic functionnalities required by an explorer.
|
||||
- I am working on this plugin to learn lua, learn neovim api and create a **simple** file explorer with features i need.
|
||||
- I really don't like any of the vim trees, they are all too complicated for their purposes and are kind of buggy. I have my shell to do most commands.
|
||||
- This plugin wont work on windows.
|
||||
|
||||
## Goals / Features
|
||||
|
||||
### 0.1
|
||||
- [ ] moving around the file structure like any basic tree
|
||||
- [x] moving around the file structure like any basic tree
|
||||
- [x] open file in current buffer or in split with FzF like bindings (CR, C-v, C-x)
|
||||
|
||||
### 0.2
|
||||
- [ ] add / delete file in directory
|
||||
- [ ] quickly find file in the directory structure
|
||||
|
||||
### 0.3
|
||||
- [ ] icons for files
|
||||
- [ ] simple git integration (color of file changing when staged/changed)
