deb-gview - Online in the Cloud

PROGRAM:

NAME

deb-gview - GNOME viewer for .deb package files and contents

DESCRIPTION

deb-gview displays Debian control information, devscript details and details of the files
that would be installed (names, sizes and locations). Files within the package can be
viewed within the package or externally.

deb-gview accepts package files on the command line to support the 'open' command in
various file managers, one window for each package. Individual views can be closed
independently or simultaneously using 'Quit'.

Packages do not need to be installed to be viewed. Packages do not need to be suitable for
installation, e.g. a foreign architecture.

Package files and .changes files can be viewed from local and remote filesystems.

When loading .changes files, deb-gview will load each referenced package in a new window.
When opening a .changes file from the deb-gview toolbar, the original window is not
changed.

When opening Debian packages files from the deb-gview toolbar, the package data will
replace the current window data.

Usage:
deb-gview [OPTIONS] [file...]

COMMAND:
file
One or more Debian package files (.deb) to preload or a .changes file referencing
various package files.

Individual package files or a set of packages referenced in a .changes file can be
viewed from local and remote filesystems.

GUI Options:
See also gtk-options (7).

FILE PREVIEWS

deb-gview has migrated to the XDG specification for config files and uses a dot-file in
your XDG config directory (default: ~/.config/deb-gview/preview) to specify which
applications should be used to preview files from the package. You are free to edit this
file, deb-gview will not modify it, although the defaults will be replaced if the file is
deleted.

Any previous config in ~/.deb-gview/preview will be moved into the new file but the
~/.deb-gview directory will be preserved - feel free to delete it once any other files are
moved to the new location.

The first matching pattern will be used, so put the most general wildcards (like *) at the
end of this file.

GROUPS
The first group contains two deb-gview default settings. 'terminal' determines which
application to use for viewers that need a terminal. You may want to change this to
gnome-terminal or konsole from the rather limited xterm default. 'execute_command'
specifies the command to pass to the terminal application to load an external command
within the terminal. Most terminal emulators support '-e' for this command.

Subsequent group names need to be unique but have no other meaning to deb-gview.

KEYS
pattern: glob-style pattern to match the location of the file in the package (not the
filesystem).

viewer: the program to call to view the file content (which must exist in your system
PATH).

use_terminal: whether to start the viewer in a terminal, TRUE or FALSE.

binary_file: whether the viewer requires the content as a binary file, TRUE or FALSE.
Typically, image previews require a binary file.

file_suffix: if the viewer needs a specific suffix, specify it here. Note that deb-gview
does not insist that the suffix of the temporary file matches the suffix of the file
within the package, it is up to you to ensure that the suffix is suitable for the viewer
you want to use. Leave blank for no suffix.
