Summary: Preload the menu.

Initial Comment:
It would be nice to add the posibility of preload the
menu at start. In that way, the first click on the menu
is gonna be very fast, without having to load all the
icons.

More generally, it could be good to lasily preload the files
which are assumed to be loaded after the startup.


I made it for me. But maybe it could be added to the default
user startup file.


~/.icewm/startup:
---
#!/bin/sh
(nice -n 40 ~/.icewm/preload > /dev/null) &
---


~/.icewm/preload:
---
#!/bin/sh
# preload lazily in cache some files
# which are assumed to be read
# after startup

is_enough_memory() {
        ((`grep -m 1 -i MemFree /proc/meminfo|awk '{print
$2}'` > 8192))
}

load_in_cache() {
        echo load $1
        head --bytes 1m $1 > /dev/null
}

typeset -i preloading_stopped=0

# target files of the toolbar
for i in `grep '^prog' ~/.icewm/toolbar|awk '{print $4}'`; do {
        sleep .5
        if is_enough_memory; then {
                load_in_cache `which $i`
        } else {
                preloading_stopped=1
                break
        } fi
} done

# images of the menu
if !((preloading_stopped)); then {
        sleep .5
        if is_enough_memory; then {
                for i in `grep '^menu' ~/.icewm/menu|sed
's,^menu \.*\,,'|sed 's, {$,,'|sort|uniq`; do {
                        load_in_cache $i
                } done
        } else {
                preloading_stopped=1
        } fi
} fi

if ((preloading_stopped)); then {
        echo 'not enough free memory : preloading stopped'
} fi
