## noice
A fork of the [noice](http://git.2f30.org/noice/) file browser to make it more friendly towards major distros (which `suck more` by some standards).

### Introduction
noice is a blazing-fast terminal file browser with easy keyboard shortcuts for navigation, opening files and running tasks. noice is developed with terminal based systems in mind. However, the incredible user-friendliness and speed make it a perfect utility on modern distros. Navigate to `/usr/bin` from your regular file browser and noice to feel the difference.
The only issue with noice is hard-coded file association. There is no config file (better performance and simpler to maintain) and you have to modify the source to change associations (see [how to change file associations](#change-file-associations)). This fork solves the problem by adding the flexibility of using the default desktop opener at runtime. There are several other improvements too (see [fork-toppings](#fork-toppings)).
Have fun with it! PRs are welcome. Check out [#1](https://github.com/jarun/noice/issues/1).
### Why fork?
I chose to fork noice because:
- one can argue my approach deviates from the goal of the original project - keep the utility `suckless`. In my opinion evolution is the taste of time.
- I would like to have a bit of control on what features are added in the name of desktop integration. A feature-bloat is the last thing in my mind.
### Default features
- Super-easy navigation
- Open files with default-associated programs
- Jump to home directory
- Filter contents in current directory
- Show/hide hidden files
- Sort entries by time modified
- Spawn a shell in current directory
- Run `top`
- Open a file with `vim` or `less`
### Fork toppings
- Behaviour and navigation
- Case-insensitive alphabetic content listing instead of upper case first.
- Roll over at the first and last entries of a directory (with Up/Down keys).
- File associations
- Environment variable `NOICE_OPENER` to override all associations and open all files with your desktop environments default file opener. Examples:
export NOICE_OPENER=xdg-open
export NOICE_OPENER=gnome-open
export NOICE_OPENER=gvfs-open
- Selective file associations (ignored if `NOICE_OPENER` is set):
- Associate plain text files with vim (using `file` command)
- Remove video file associations (to each his own favourite video player)
- Associate common audio mimes with lightweight [fmedia](http://fmedia.firmdev.com/)
- Associate PDF files with [zathura](https://pwmt.org/projects/zathura/)
- Removed `less` as default file opener
- Use environment variable `NOICE_FALLBACK_OPENER` to open other non-associated files
- Compilation
- Use `-O3` for compilation, fixed warnings
- Added compilation flag `-march=native`
- Remove generated config.h on `make clean`
### Installation
noice needs a curses implementation and standard libc.
Download the [latest master](https://github.com/jarun/noice/archive/master.zip) or clone this repository. Compile and install:
$ make
$ sudo make install
No plans of packaging at the time.
### Usage
Start noice (default: current directory):
$ noice [path_to_dir]
`>` indicates the currently selected item.

### Help
$ man noice
### Change file associations
If you want to set custom applications for certain mime types, or change the ones set already (e.g. vim, fmedia, zathura), modify the `assocs` structure in [config.def.h](https://github.com/jarun/noice/blob/master/config.def.h) (it's easy). Then re-compile and install.
