### nlay
|
||||
|
||||
nnn comes with an easily customizable bash shell script to handle files - nlay. To know more about it, visit [nlay on wiki](https://github.com/jarun/nnn/wiki/all-about-nlay).
|
||||
|
||||
### Installation
|
||||
|
||||
nnn needs libreadline, libncursesw (on Linux or ncurses on OS X) and standard libc.

|
||||
#### File handling
|
||||
|
||||
nnn is designed to play files using multiple strategies (in order of decreasing priority):
|
||||
- Set `NNN_OPENER` to let a desktop opener handle it all. E.g.:
|
||||
|
||||
export NNN_OPENER=xdg-open
|
||||
export NNN_OPENER="gio open"
|
||||
export NNN_OPENER=gvfs-open
|
||||
- Selective file associations (ignored if `NNN_OPENER` is set):
|
||||
- vi - plain text files (determined using file)
|
||||
- mpv - common audio and video mimes
|
||||
- [zathura](https://pwmt.org/projects/zathura/) - pdf files
|
||||
- to customize further see [how to change file associations](#change-file-associations)
|
||||
- Set `NNN_FALLBACK_OPENER` as the fallback opener:
|
||||
- if the executable in static file association is missing
|
||||
- if a file type was not handled in static file association
|
||||
- If nnn recognizes the file extension, it invokes nlay (which invokes the players). Default players:
|
||||
- mpv - audio and video
|
||||
- viewnior - image
|
||||
- [zathura](https://pwmt.org/projects/zathura/) - pdf
|
||||
- vim - plain text
|
||||
- to add, remove recognized extensions in nnn, see [how to change file associations](#change-file-associations)
|
||||
- If a file without any extension is a plain text file, it is opened in vi
|
||||
- Set `NNN_FALLBACK_OPENER` as the fallback opener. E.g.:
|
||||
|
||||
export NNN_FALLBACK_OPENER=xdg-open
|
||||
export NNN_FALLBACK_OPENER="gio open"
|
||||
export NNN_FALLBACK_OPENER=gvfs-open
|
||||
- To enable the desktop file manager key, set `NNN_DE_FILE_MANAGER`. E.g.:
|
||||
|
||||
export NNN_DE_FILE_MANAGER=thunar
|
||||
export NNN_DE_FILE_MANAGER=nautilus

||||
#### Change file associations
|
||||
|
||||
If you want to set custom applications for certain mime types, or change the ones set already (e.g. vi, mpv, zathura), modify the `assocs` structure in [config.def.h](https://github.com/jarun/nnn/blob/master/config.def.h) (it's easy). Then re-compile and install.
|
||||
If `NNN_OPENER` is not set, nnn tries to recognize a file by the file extension and invokes nlay. To change the extensions recognized by nnn, modify the `assocs` structure in [config.def.h](https://github.com/jarun/nnn/blob/master/config.def.h) (it's easy). Then re-compile and install.
|
||||
|
||||
If you want to add a file extension mainline, please raise a bug. Without it nnn will not invoke nlay.
|
||||
|
||||
nlay has provisions (disabled by default) to handle a specific file extension too. However, the extension should be recognized by nnn first.

||||

# nlay: a customizable script to play files in different apps by file type
|

#
|
||||
# usage: nlay file type
|
||||
#
|
||||
# MUST READ:
|
||||
#
|
||||
# 1. Feel free to change the default apps to your favourite ones.
|
||||
# If you change the app for a group you may also need to modify the bg
|
||||
# setting. If bg is set the app is detached and started in the background in
|
||||
# silent mode.
|
||||
#
|
||||
# The bg setting depends on personal preference and type of app, e.g.,
|
||||
# I would start vim (CLI) in the foreground but Sublime Text (GUI) in the
|
||||
# background.
|
||||
#
|
||||
# Check (and TOGGLE as you wish) the default bg settings.
|
||||
#
|
||||
# 2. Detached apps are not killed when nnn exits. Use kill(1) or killall(1) to
|
||||
# to stop console based background apps.
|
||||
#
|
||||
# 3. Assuming you don't to play multiple audio/video files simultaneously,
|
||||
# nlay kills any running instances of the audio/video player in bg mode.
|
||||
#
|
||||
# 4. Keep a personal backup (on GitHub Gist maybe?) of this file if you modify
|
||||
# it. nlay is OVERWRITTEN during nnn upgrade.
