# Tabbed perl extension for rxvt-unicode terminal emulator.
|
|
# Modified by Roman Dobosz <gryf73 at gmail dot com>
|
|
#
|
|
# 2008-08-22 18:01:55
|
|
# - Modified shortcuts for tab navigation - now it uses shift + left/right
|
|
# arrow to navigate, also creating new shell is changed to CTRL+Shift+n.
|
|
# - Added shortcuts to move tab between others witch CTRL left/right arrow
|
|
# - Added some predefined actions - CTRL+Shift+r for "su -" command and
|
|
# CTRL+Shift+m for "mc" and other like named ssh sessions.
|
|
# - Added labels for custom shells (like "root", "mc" and so on)
|
|
#
|
|
# Please note, I don't know Perl!
|
|
#
|
|
# 2009-11-23 11:11:19
|
|
# - Added shortcuts for apps with Mod4 key (mutt as an example)
|
|
#
|
|
# 2009-11-23 13:25:13
|
|
# - Merged activity indicator from
|
|
# http://mina86.com/2009/05/16/tabbed-urxvt-extension/#more but without
|
|
# changes on tabs (like adding term title just behind all tabs). New
|
|
# resources can be use to change defaults (as in original solution):
|
|
# - tabbed-timeouts with format:
|
|
# (<timeout> ":" <character> ":")* <timeout> ":" <character> ":"
|
|
# default '16:.:8:::4:+'. Asterisk is always present as a first indicator
|
|
# character, just like in original tabbed extension.
|
|
# - new-button, default to 'true'. Used to disable [NEW] button.
|
|
#
|
|
# 2009-11-24 23:34:51
|
|
# - Added possibility to quick switch between first ten tabs with predefined
|
|
# combination of CTRL+1..0 keys, which will activate proper tab.
|
|
# - Added possibility to remove numbers from tab names by setting resource
|
|
# tab-numbers to false.
|
|
#
|
|
# 2009-11-25 21:40:30
|
|
# - Added colors for tabs, which have activity on them. First is to be set
|
|
# when first activity (active-fg, defaults to red) appear on inactive tab.
|
|
# Last one (actived-fg, blue by default) is set when there is no more
|
|
# possible timeouts. Third one (actives-fg, purple) is set on all in between
|
|
# of these two.
|
|
#
|
|
# 2010-07-25 13:49:01
|
|
# - Integrated renaming ability for tabs from stepb
|
|
# (http://github.com/stepb/urxvt-tabbedex)
|
|
#
|
|
# 2010-08-12 20:54:46
|
|
# - Added functionality to create definitions of custom shells as a X
|
|
# resource, under common tabcmds name. This functionality also deprecates
|
|
# feature called here as a predefined actions. Without any configuration
|
|
# only simple shell is available under CTRL+SHIFT+N shortcut. After creating
|
|
# first custom shell this default is not available.
|
|
#
|
|
# Let's assume, that one want to mimic previous configuration, that means
|
|
# three kind of custom shells: simple one (default shell in the system),
|
|
# midnight commander and root (namely - su command). Three resources should
|
|
# be created:
|
|
#
|
|
# URxvt.tabbedalt.tabcmds.1: N|shell
|
|
# URxvt.tabbedalt.tabcmds.2: R|root|su -
|
|
# URxvt.tabbedalt.tabcmds.3: M|mc|mc
|
|
#
|
|
# URxvt.tabbedalt.tabcmds.[number] is a ordinal number, started from 1. There
|
|
# shouldn't be gaps between numbers, otherwise custom shells defined after a
|
|
# gap will not work.
|
|
#
|
|
# Resource values are two or three pipe separated values, which are in order:
|
|
# - shortcut key, which will be used for invoking custom shell together with
|
|
# CTRL+SHIFT keys. Mod4 (aka Super or Windows key) are not supported, and
|
|
# most probably will be removed from script soon, as lots of window
|
|
# managers out there make a big use of those keys.
|
|
# Note: There is limitation for characters used as a shortcut. Because some
|
|
# of them are used for control terminal itself (i.e. CTRL+SHIFT+D may not
|
|
# work), and also other characters (digits, some special characters etc.).
|
|
# Letters are case insensitive.
|
|
# - name of the tab, it could be anything but the pipe.
|
|
# - optional command. If omitted, simple shell will be launched.
|
|
#
|
|
# 2010-08-28 10:17:02
|
|
# - Removed tab_property_notify hook, because in certain circumstances it
|
|
# provides memory consumption. It is especially well seen by running
|
|
# mocp[1] and play internet radio station (i.e digitalgunfire.com, but
|
|
# there can be others). Observe memory taken by urxvt with top or ps. Also,
|
|
# original tabbed extension is affected.
|
|
#
|
|
# This change will affect i.e. dynamic font change - it will not expand
|
|
# window to reflect size of a font. Switching to next tab and back will
|
|
# rearrange content of a tab to current window size.
|
|
#
|
|
# If anyone have a better idea how to fix memory consumption which is taking
|
|
# place in copy_properties(), please step forward :)

|
#
|
|
# 2011-07-12 21:05:26
|
|
# - Fixed defaults for not defined tabcommands - now it is possible to use
|
|
# tabbed just as described.
|
|
# - Added some sort of primitive session ability, defined via resource
|
|
# session, which should contain pipe separated shortcuts defined in tabcmds
|
|
# resource. If there is no shortcuts (or wrong was defined), plain shell tab
|
|
# will appear.
|
|
#
|
|
# 2013-11-12 09:23:49
|
|
# - Restored tab_property_notify hook. Whatever was the cause of the memory
|
|
# consumption is gone or doesn't have anything to do with that function.
|
|
#
|
|
# 2013-11-26 19:31:55
|
|
# - Added parentheses for hook, should work on Debian now.
|
|
#
|
|
# 2019-06-05 10:55:37
|
|
# - fixed couple of bugs regarding session
|
|
# - changed default colors to more sane values
|
|
#
|
|
# 2019-09-13 15:15:18
|
|
# - Added shortcut for creating new shell like in original tabbed
|
|
# (SHIFT+Down). It can be disabled by an option "disable-shift-down". More
|
|
# information in README.
|
|
# - Cleaned up a bit the code and comments.
