wot Techno said...

Missing xpms lead to a very long startup. For icons, what about the JQ8flat icon theme? What I do like, is that if there is available desktop space, it will tile newly opened windows. If not, they just get stacked, but over the open space. Agree with the point about not being able to minimise, although you can hide/unhide.

@goingnuts
Tried your menu script, which worked fine on 214R, but most items end up in 'Other', and the long list reaches the bottom of the screen but no scrolling - got cut off at the P's, which sounds painful, I know.

could just modify the sleep_a_little code (first time I recall noticing select() being used)

I know...try P412 and pain comes at "d..." or something like that. But it was just a quick trial - might have modify categories.
Could be that early jwm would be a better starting point but as far as I know jwm wont support multiple main menus - which is part of the fun with hazewm.

Following Techno's suggestion, I reduced the error wait. Took a 0 out of line 136 & 137 (wait_s) in misc.c. Just a quick flash now...
Code:
void DrawErrMsgOnMenu( char *str1, char *str2 )
{
   char *str;
   static int call=0;
   int wait_s;

   call++;
   str = calloc( strlen(str1)+strlen(str2)+1, 1 );
   sprintf( str, "%s%s", str1, str2 );
   if( call<5 )   XBell( dpy, 30 );
   DrawStringMenuBar( str );
   wait_s = 300000-call/5*50000;
   wait_s = wait_s>0? wait_s : 300000;
   sleep_a_little( wait_s );
   free( str );
}

I tried to change to a simple printf function in the hope that errors would end up in xerrors.log - but they do not - why?
Code:
void DrawErrMsgOnMenu( char *str1, char *str2 )
{
   //char *str;
   static int call=0;
   //int wait_s;

   call++;
   /*str = calloc( strlen(str1)+strlen(str2)+1, 1 );
   sprintf( str, "%s%s", str1, str2 );*/
   printf("hazewm error: %s%s\n", str1, str2);
   if( call<5 )   XBell( dpy, 30 );
   /*DrawStringMenuBar( str );
   wait_s = 3000000-call/5*500000;
   wait_s = wait_s>0? wait_s : 300000;
   sleep_a_little( wait_s );
   free( str );*/
}

Found a decent clock - ofclock - integrates nicely with hazewm. Although xclock have more settings I really just want to know the time...
ofclock wont swallow with jwm. Added that and some mouseclick action/control with below patch:

This is a bad case of 'coding-by-Google' but this succeeds in writing to a file:
Code:
void DrawErrMsgOnMenu( char *str1, char *str2 )
{
   FILE *file;
   file = fopen("haze_err.txt","a");
   char *str;
   static int call=0;
   int wait_s;

   call++;
   str = calloc( strlen(str1)+strlen(str2)+1, 1 );
 //  sprintf( str, "%s%s", str1, str2 );
   fprintf(file, "hazewm error: %s%s\n", str1, str2 );
   fclose(file);
 //  if( call<5 )   XBell( dpy, 30 );
/*   DrawStringMenuBar( str );
   wait_s = 1000000-call/5*500000;
   wait_s = wait_s>0? wait_s : 100000;
   sleep_a_little( wait_s );*/
   free( str );
 
}

Had no luck at all with printf (always a blank file), but eventually found a reference to fprintf and that works.
The file ends up in root/

EDIT:
Code:
file = fopen("/tmp/xerrs.log","a+");
will work, I just hadn't tried it yet...

A little known tidbit about printf - it prints to stdout which is buffered (stderr is not IIRC), so if you didn't add a '\n', it would just keep buffering until it got one. This is useful for instance if you need to use '\b' to overwrite something, but mostly to reduce unnecessary i/o.

Keef: Thanks - good hints. Now it can be reduced to
Code:
void DrawErrMsgOnMenu( char *str1, char *str2 )
{fprintf(stderr, "hazewm error: %s%s\n", str1, str2);}
and errors ends up in xerrs.log. Removed the Xbell as well - I do not hear the bells - do you?
20131010: Attached 4 patches - one fix missing fonts, one sends errors to stdout (and not to menubar) - one remove some warnings and the last adds icewm systemsounds.
For the system sounds to work compile with " -DCONFIG_GUIEVENTS" and you also needs a configured "icesound" or my replacement "newsound"...

A "collage" of hazewm-0.2 with above patches and configured with systemsounds can be downloaded here. Also a small collection of applications included (animate, montage, xdesktopwaves, calctool, identify, newsound, tcmixer, xli, combine, import, ofclock, wavplay, xmountains, convert, mcb_imagemagick, pmfree, wavrec, xsetroot, defaultaudioplayer, minimp3, pupslock,xautolock, xtp, display, mogrify, setterm, xcal, xvidcap).
Used some of technosaurus tango32xpm icons, revised the pm_haze_xdg.sh script to use desktopfiles found in /usr/share/haze/applications.

Its for fun - and a nice sandbox for test of applications that NEED root window visible (if you as user need to view what it does...)

@goingnuts, I'm guessing you built static against tinyx11, since I don't see it in top (it uses less resource than the shared build of bash)

Good work as ever, goingnuts. I bet samira was wondering if a pet would ever appear.

On my starthaze, I added
Code:
echo "xsetroot -cursor_name top_left_arrow" > $HOME/.xinitrc
to get rid of the cross-hair cursor. Just nicked it from the standard xinitrc.

That is right - top reports 376 for the static linked hazewm. Source holds a lot of code dedicated to style system8 which is never used - wonder if resource usage would be minimized if cleaned out. It would be nice to have keyboard-control of the menus as well + full screen support but I haven't been able to get that working.
Keef: Good point - I changed that to
Code:
echo "xsetroot -cursor_name left_ptr" > $HOME/.xinitrc
to give me same cursor on root window as over menus.

I don't even know what "style system8" is, I would just comment it out rather than remove it outright. Keyboard control in wm can be difficult to do right, IIRC tinywm is the most concise example I've seen (it does alt+click to drag).

I know the number of menu items is limited by size, but since haze can handle submenus, it may be useful to adapt my jwm_menu_create with the submenus part required, possibly using some tango icon defaults for submenus.

system8 is a style left over from mvlwm but not functional in hazewm anymore (behavior, decoration etc.) - might try to comment them out as you suggest - just to see influence on bin-size and resource usage.

Found a graphic view of a lot of wm and the relations here: http://www.gilesorr.com/wm/bloodlines.svg

Are there any general/common/standard rules for the categories/subcategories in the menus?

If anyone running the "hazewm-collage" leaves the desktop without activity for more than 10 minutes the xautolock triggers pupslock and screen is locked. To release it just type user/admin password.
