[Solved] Prev on specific desk & FvwmIconMan sorting?

I need to realize:

  1. Prev (Desk n, …) WindowListFunc
  2. Sort items in FvwmIconMan according to geometric information of windows,
    it’s ridiculous that a window dockes at the left side of screen while it’s iconman item
    lies to the opposite side, since my windows are not decorated.

Currently I use following codes to achieve my purpose, but I’m not content with the them for :
A. Hard-disk access is too slow.
B. Is it possible that lines 4 & 7 are executed before lines 3 & 6 has been totally flushed to hard-disk?

  AddtoFunc   FuncPrevIdOnDesk
1 + I UnSetEnv fvwm_PrevIdOnDesk
2 + I PipeRead '>/tmp/fvwm.wid'
3 + I All (CurrentPageAnyDesk,!CurrentDesk,AcceptsFocus,State 1) PipeRead '[ $$$$[w.desk] -eq $$0 )) ] && echo $$$$[w.id] >> /tmp/fvwm.wid'
4 + I PipeRead 'echo WindowId `head -1 /tmp/fvwm.wid` SetEnv fvwm_PrevIdOnDesk `head -1 /tmp/fvwm.wid`'
 
 AddtoFunc   FuncTitleSerialization
5 + I PipeRead '>/tmp/fvwm.geoname'
6 + I All (CurrentPage,Visible,AcceptsFocus) PipeRead `echo -e "$$$[w.y]\\t$$$[w.x]\\t$$$[w.width]\\t$$$[w.height]\\t$$$[w.name]" >> /tmp/fvwm.geoname`
7 + I PipeRead `sort -n /tmp/fvwm.geoname|awk -F'\\t' '{print "Style "$$$NF" TitleFormat "NR") %n"}'`

DestroyModuleConfig FvwmIconMan: *
*FvwmIconMan: Resolution Page
*FvwmIconMan: Sort name
...

Can someone tell me a better way ( without hard-disk access ) to achieve my purpose?
Thank in advance!

It’s not “ridiculous”. It’s just unfortunate that FvwmIconMan can’t read your mind.

This has nothing to do with disk flushing. So no. PipeRead blocks.

I’ll try that.

Got it.

And I have no doubt about them.

Thank you for your reply, Thomas:P
