Used for hiding/unhiding programs to acheive quake-dropdown-like-functionality. Can create a dropdown window if one does not already exist and provides options to control the intial size and position, e.g. to leave panels visible. When used with a terminal, provides the option to specify the name of a tmuxinator or tmux session to automatically start or attach to.
|
|
|
|
Also supports the ability to auto-hide and auto-show. For example, this can be used to automatically hide a window when opening something, e.g. image viewer, video player, etc. from it, and then re-show the window whenever the image view, video player, etc. is closed.
|
|
|
|
Takes a window as an argument or one of auto_show, auto_hide, or toggle_auto_hide. 'toggle_auto_hide' toggles whether calling 'auto_hide' or 'auto_show' will have any effect. 'current' will turn the current window into a dropdown.
|
|
|
|
usage: tdrop [options] <program or 'current'> or one of <auto_show/auto_hide/toggle_auto_hide>
|
|
options:
|
|
-h height specify a height for a newly created term (default: 100%)
|
|
-w width specify a width for a newly created term (default: 45%)
|
|
-x pos specify x offset for a newly created term (default: 0)
|
|
-y pos specify y offset for a newly created term (default: 1)
|
|
-s name name for tmux or tmuxinator session (if not given, will not use tmux)
|
|
-n num num or extra text; only needed if want multiple dropdowns of same program (default: "")
|
|
-p cmd provide a pre command to float the window if necessary
|
|
-P cmd provide a post command to float the window if necessary
|
|
-O cmd provide a one time command only for when a dropdown is created/initiated (useful for 'tdrop -c')
|
|
-W the given program is not a terminal (or lacks an -e flag) (default: assume it IS a terminal)
|
|
--clear clear saved window id; useful accidentally make a window a dropdown (e.g. '$ tdrop --clear current')
|
|
--no-cancel don't cancel auto-showing
|
|
(default is to prevent this when manually toggling a term after it is auto-hidden)
|
|
--help print help
