.Sh SYNOPSIS
|
|
.Nm noice
|
|
.Op Ar dir
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is a simple and efficient file browser that gets out of your way
|
|
as much as possible. It was initially implemented to be controlled
|
|
with a TV remote control.
|
|
.Pp
|
|
.Nm
|
|
defaults to the current directory if
|
|
.Ar dir
|
|
is not specified. As an extra feature, if
|
|
.Ar dir
|
|
is a relative path,
|
|
.Nm
|
|
will not go back beyond the first component of the path using standard
|
|
navigation key presses.
|
|
.Pp
|
|
.Nm
|
|
supports both vi-like and emacs-like key bindings in the default
|
|
configuration. The default key bindings are described below;
|
|
their functionality is described in more detail later.
|

.El

.Pp
|
|
Backing up one directory level will set the cursor position at the
|
|
directory you came out of.
|
|
.Sh CONFIGURATION
|
|
.Nm
|
|
is configured by modifying
|
|
.Pa config.h
|
|
and recompiling the code.
|
|
.Pp
|
|
The file associations are specified by regexes
|
|
matching on the currently selected filename. If a match is found the associated
|
|
program is executed with the filename passed in as the argument. If no match
|
|
is found the program
|
|
.Xr less 1
|
|
is invoked. This is useful for editing text files
|
|
as one can use the 'v' command in
|
|
.Xr less 1 to edit the file using the EDITOR environment variable.
|
|
.Pp
|
|
See the examples section below for more information.
|
|
.Sh FILTERS
|
|
Filters allow you to use regexes to display only the matched
|
|
entries in the current directory view. This effectively allows
|
|
searching through the directory tree for a particular entry.
|
|
.Pp
|
|
Filters do not stack on top of each other. They are applied anew
|
|
every time.
|
|
.Pp
|
|
To reset the filter you can input an empty filter expression.
|
|
.Pp
|
|
If
|
|
.Nm
|
|
is invoked as root the default filter will also match hidden
|
|
files.
|
|
.Sh ENVIRONMENT
|
|
The SHELL, EDITOR and PAGER environment variables take precedence
|
|
when dealing with the !, e and p commands respectively.
|
|
.Sh EXAMPLES
|
|
The following example shows one possible configuration for
|
|
file associations which is also the default:
|
|
.Bd -literal
|
|
struct assoc assocs[] = {
|
|
{ "\\.(avi|mp4|mkv|mp3|ogg|flac|mov)$", "mplayer" },
|
|
{ "\\.(png|jpg|gif)$", "feh" },
|
|
{ "\\.(html|svg)$", "firefox" },
|
|
{ "\\.pdf$", "mupdf" },
|
|
{ "\\.sh$", "sh" },
|
|
{ ".", "less" },
|
|
};
