Worker file manager: directory list view and commands.

Directory list view.

Introduction.
Worker uses a two-pane approach for displaying directory content (also known as an orthodox file manager). Each of both sides supports several modes for showing different kind of information (directory mode, information mode, text view mode, ...).

One side is always active or source of an operation, while the other side is inactive or destination of an operation. The active panel is indicated by a red list view bar on top of the list view area (the colors can be configured). Switching sides is done by clicking on the corresponding area or by pressing TAB in the default configuration.

Directory mode.
The directory list view (directory mode) is the main view for browsing directory content. The current directory name is shown in the editable path field at the bottom of the list view. The window title also contains the path for the active side.

The visible columns can be configured and usually contains the file name, file size, permissions, and file type information. The width of a column is dynamic by default but can be changed by moving the mouse in between two headers and clicking on the header separator. Double-clicking it will change back to dynamic width.

By clicking in the header, the sort mode can be toggled.

List view bar.
The list view bar on top of each side (above the list view) displays status information about the current mode. For the directory mode this includes the following information:
  • the filter string (if active)
  • a short status of sort and filter mode
  • the mode name
  • the free space in the shown directory
The status string consist of the following elements: The first character stands for the sort mode currently used to sort the files and directories (N = sort by name, S = sort by size, T = sort by modification time, ...). The next character (if visible) indicates that the entries are reverse sorted. The third character "H" indicates (if visible) that hidden files are not shown. At fourth position an asterisk indicates an active filter. The following text shows the name of currently active mode of the corresponding area below the list view bar. The most important mode is the "directory mode" which list files of any directory. Other modes are the "information mode" for displaying detailed information about an entry, the "show image mode" for displaying images in the area below, and the "text view mode" for displaying the content of the active entry.

File name prefixes.
In front of file names a special character is used to differentiate between different kind of files:
CharacterMeaning
/Directory entry
~Symbolic link to a directory
*Executable file
@Symbolic link to a file
!Broken symbolic link (target does not exists or is inaccessible
-character device
+block device
=socket
|pipe (named fifo)

regular file

Builtin commands.
Worker supports several internal commands that work on the selected entries, as well as using external commands to execute arbitrary applications.

Change list view settings Settings opens the dialog for configuration of the panel modes
toggle list view mode Settings directly switches to a different panel mode
Change layout Settings changes the layout of the main window
script Scripting allows to program a virtual machine for more complex internal commands
do nothing Scripting a command without any effect (can be used to stop implicit recursive command execution due to file type hierarchy)
path to other side Other Shows the current directory in the other side
Quit worker Other quits worker
Reload Other Reload the directory content
own command Other executes external programs
directory size Other calculates the size of the directory content
start prog Other starts an external program
edit path (in the text field) Other edits the path field
activate shortkey from list Other activates a shortkey from the list of all available shortkeys

External commands.
By using the internal command "own op" it is possible to execute any application in a flexible way. Selected files can be given as arguments, and more sophisticated arguments can be built by using special flags for replacements.
