Info

Der Ion Fenster.- oder Windowsmanager ist der Nachvolger vom PWM Fenstermanager. Er läuft unter dem X11 System, ist extrem klein, schlank und schnell (Ressourcenschonend). Das besondere an Ion ist das sich alle geöffneten Fenster niemals überlappen. Dies heisst das alle geöffneten Fenster zu jeder Zeit sichtbar sind. Funktionieren tut die ganze Sache mit Hilfe eines Areals in welchem ein Fenster oder auch mehrere geöffnet werden können. Der gesamte Bildschirm wird unter den Areals oder auch Frames genannt aufgeteilt. Sind in einem Areal mehrere Fenster geöffnet, so bekommt hier jedes seine eigene Registerreiter ueber welche es angewählt werden kann. Im Screenshot neben an sind derzeit 4 Areals (Frames) zu sehen, in jedem ist die Konsole-RoxTerm und in ihr ein Programm gestartet. Diese gestartete Anwendung (RoxTerm/Programm) sind in einem Fenster untergebracht welches einen Registerreiter hat.


Lizenz

Der Macher von Ion - Tuomo Valkonen hat eine Lizenzaenderung vorgenommen:

„Versions not based on the copyright holder's latest release (on the corresponding "branch", such as Ion3(tm)), must within 28 days of this release, be prominently marked as (potentially) obsolete and unsupported. Significantly altered versions may be provided only if the user explicitly requests for those modifications to be applied, and is prominently notified that the software is no longer considered the standard version, and is not supported by the copyright holder. The version string displayed by the program must describe these modifications and the "support void" status.“

Dies heisst soviel wie das alle (Distributoren) die Ion3 Pakete anbieten, ihre Pakete die nach einem naechsten Ion3 Release von Tuomo Valkonen aktualisieren muessen. Falls dies nicht spaetestens nach 28 Tagen geschieht, muessen sie als veraltet oder unsupported markiert werden.


Nach dieser Bekanntgabe haben die Distributionen Arch Linux, FreeBSD und NetBSD ihre Ion3 Pakete herrausgenommen.


Alternativen

Als Alternative zu Ion gibt es folgende andere Fenstermanager:

  • LarsWM
  • Ratpoison
  • StumpWM
  • WMI
  • WMII
  • TrsWM
  • DWM


Funktionstasten

In der Regel sind die Funktionstasten bei Ion folgendermaßen bestückt:

  • F1 - Die Manpages anzeigen
  • F2 - Ein eues Terminal
  • F3 - Ein Programme starten
  • F4 - Eine SSH-Verbindung herstellen
  • F5 - Datei editieren
  • F6 - Datei anzeigen
  • F9 - Erstellen einer neuen Arbeitsfläche (Areal/Frame)
  • F12 - Das Hauptmenü


  • ALT + S - Eine Area oder Frame vertikal splitten
  • ALT + KS - Eine Area oder Frame horizontal splitten


Installation

Debian

Wie immer gestaltet sich die Installation unter Debian recht einfach mit Hilfe von APT.

  • Die Ion3 Version liegt derzeit bei GNU/Debian im SID Non-Free Bereich.
  • Ausgenommen Debian Sarge:
    • ion3 (20050502-2)
apt-get update
apt-get install ion3


Konfigurationsdateien

ämtliche Konfigurationsdateien welche Systemweit für alle Benutzer gelten sind in der Regel unter /etc/X11/ion3 zu finden. Wer seinen Ion nicht Systemweit für alle gleich sondern für jeden Benutzer anderst konfigurieren möchte kann hierzu die entsprechenden Konfigurationsdateien im /home/ ~ /.ion3 Verzeichniss anlegen.

Die wohl wichtigsten Konfigurationsdateien sind:

  • cfg_ioncore.lua
  • cfg_statusbar.lua
  • cfg_menu.lua

In der ersten Konfigurationsdateien koennen Tastenkombinationen entsprechend konfigurirt werden wie auch die F-Tasten Belegung. In der Zweiten werden Einstellungen zur Statusbar vorgenommen. Diverse Lua-Scripts fuer die Statusbar koennen hier eingebunden werden. In der letzten kann das Menue konfiguriert werden.

F-Tasten

Die Funktion der F-Tasten ist eigentlich gar nicht mal so schlecht, doch leider bei manchen Anwendungen welche selbst die F-Tasten benötigen extrem störend. zum Beispiel wird beim Arbeiten im MC das Betätigen der F-Tasten die Funktion vom Ion und nicht vom MC selbst ausführen. Drücke ich z.B. F-5 so wird die Option von Ion für das Editieren geöffnet anstelle die Option im MC für das Kopieren einer Datei. Wie können wir das Problem am einfachsten lösen. Ganz einfach, wir entfernen die Funktionen aus der entsprechenden Konfigurationsdatet so, das die F--Tasten von F1--10 keine Funktion mehr in Ion beim drücken haben.

Tastenkombinationen

Das aufrufen des Menüs lassen wir weiterhin auf der F12 Taste liegen. In dem von mir hier gezeigten Beispiel ist es als Terminal RoxTerm und Rxvt auf die Tastenkombination ALT+T und ALT+R gelegt. Mit der Kombination ALT+E wird Esetroot gestartet um ein Wallpaper bei transparentem Terminal anzeigen zu lassen (Der Pfad zum Wallpaper muss entsprechend angepasst werden). Bai ALT+W wird eine neue Arbeitsflaeche erstellt durch welche mit ALT+1 bis ALT+9 durchgewechselt werden kann.

Die Zeile

template="[ %date || load: %05load_1min ",

ist die interessante. Hier kann entsprechend konfiguriert werden. In meinem Beispiel wird der Tag, Datum, Uhrzeit und Loadwert angezeigt. Ich habe die Defaulteinstellung ebenfalls in der Datei stehen lassen und zudem eine von mir verwendete Version mit eingetragen bei welcher ein paar Lua Skripte mit eingebunden werden um CPU Auslastung, RAM Speicherverbrauch und Netzwerkdurchlass anzuzeigen.

Damit zusaetzliche Lua Skripte unter Ion funktionieren muessen sie ins ion3 Verzeichniss kopiert werden. In den Skripten selbst ist meistens genau beschrieben wie weiter vorgegangen werden muss. Meistens muessen Pfade angepasst werden oder ein paar kleine Einstellungen wie z.B. Netzwerkinterface usw. Bekommen tut man diese Skripte auf der Ion Webseite oder beim Distributor. Ich fuege ein paar Skripte hier ins Wiki mit ein, es sind diese welche auch in dem Konfigurationsbeispiel der cfg_statusbar.lua eingetragen sind.

statusd_mem.lua

Fuer die Anzeige des freien RAM Speichers in der Statusbar.

Wird durch MEM Used: %mem_hused MB - Free: %mem_hfree MB eingebunden.

-------------------------------------------------------------------------------------------
--
--	PURPOSE: 
--	Shows system available memory catching [free] command outputs.
--	It is intended to make it simpler than statusd_meminfo, plus user configurable 
--	measurement units and alarms for "all" available memory metters. 
--
--	USAGE:
--	Just set any of the following labels on cfg_statusbar.lua: %mem_hused, %mem_shared
--	%mem_free, %mem_hfree, %mem_swap, %mem_used, %mem_cached. Example: [MF: %mem_free]
--	
--	MEANINGS:
-->	** "mem_hfree" poses as "htop free memory" or "mem_free +cached +buffers",
--	in oposition, "mem_hused" is "mem_used -cached -buffers"; other labels have
--	transparent meanings.
--
------- CONFIG EXAMPLE:	------------------------------------------------------------------
--
--	To modify settings is quite simple and flexible, write (on cfg_statusbar.lua)
--	something like this, without comments:
--					mem = {
--					   update_interval = 15*1000, --> Milliseconds
--					   free_alarm = 25,   --> Limits percentaje ...
--					   used_alarm = 65,
--					   units = "m" 	      --> "g" or "k" too
--					   }
--	Write only the settings that do you want to change or leave this section as is...
-->	** "update_interval" means "time in milliseconds to update info (default = 15)"
--	"xx_alarm" means "do a color advise when memory *percentage* reaches this value".
--	(both defaults are 50). "units" means Gb "g", Mb "m" or Kb "k" (default = "m")
------------------------------------------------------------------------------------------
--
--	NOTES: 
--    *	Alarms for used memory are inverse to alarms for free memory (think about it...)
--	"mem_total" label is useless. If total memory varies, its time to open your
--	hardware and check this script from barebone. Seriously, may be your video or wifi
--	devices were claiming some free R.A.M. on your machine start-up. 
--	However, I included "mem_total" just in case.
--   ** This script has non blocking I/O.

-- $Id: statusd_cpustat.lua 80 2007-03-10 00:16:09Z tibi $

-- statusd_cpustat.lua -- CPU monitor for Ion3's statusbar

-- version : 0.3
-- date    : 2007-03-10
-- author  : Tibor Csögör <tibi@tiborius.net>

-- Shows the CPU utilization of the system similiar to top(1).
-- This script depends on the /proc filesystem and thus only works on Linux.
-- Tested with kernel 2.6.16.

-- Configuration:
-- The following placeholders (with a "cpustat_" prefix) can be used in the
-- statusbar template: `user', `nice', `idle', `system', `iowait', `irq',
-- `softirq' and `steal'.  In addition, `system_adj' sums up the last 5 fields.
-- For a compact output simply use the `cpustat' placeholder.

-- This software is in the public domain.
