Today the classic, and old, Common Desktop Environment (a.k.a. CDE) was released into the Open Source world.
You can get the very alpha version at SourceForge.
I haven’t been able to get a running version by now, but I keep trying.
Good job, guys.
Working with git a lot I decided I needed some git status in my
prompt.
I searched the web and some solutions where almost what I wanted and this one by Sebastian Celis came very close.
But it didn’t work with my version of zsh, because that didn’t seem to
understand the =~ operator.
I also think Sebastian makes things over complicated and so I changed some things aroud.
This is what I came up with:
Today I released version 0.8 of We-Blog.
I created a Google project and a Google discussion group.
Version 0.8 is now the stable branch and 0.9 the development branch.
Well, to be really honest, not that much. I fixed some minor bugs and
did a lot of code cleanup. Although the original code of Jaromir was
very nice, there was some room for improvement. I removed a lot of
double functions and variables and put them all together in a We.pm
Perl module. Saves a lot of work with an update.
It often happens that I get into a situation where I need to know key
codes of pressed keys. On my Mac that’s simple. Just use the Key Codes
by Many Tricks.
But on Linux I constantly was trying to find out which key produced what.
So I ended up writing a program for that. I started of in the shell, but that ended up being rather tricky and unnecessary complicated. So I redid the whole thing in C.
Today I’ve posted a new version of the header program.
Nothing really fancy happened, just added support for zonefiles, in
this case the Bind ones.
It’s available at the usual places.
I’m creating a Puppet Starter Kit with some standard manifests
included and a complete set of documentation. All documentation should
be written in Markdown
and will be served by Markdoc. But I want to
generate all Markdown files from the Puppet manifests, so I only need to
document the manifest file. Generating the Markdown is not that
difficult, except that I kept ending up with empty lines at the top of
the manifest code and I wanted to get rid of those. Of course this
should be done with sed, because the whole generation process is
written in bash. When playing around with sed I found ~ sed
`/./,$!d' filename ~ which, I think, is genius in it’s simplicity.
After you find something, do not remove. Life in UNIX and Linux is nice!
When working with Puppet and a VCS (like git and SVN) it’s nice to
have a simple way of updating the Puppet tree.
My tree is always in /etc/puppet and owned by user and group
puppet. User puppet is allowed to checkout the complete tree from
git or subversion.
I have created two one-liners to update the complete tree and make sure all rights are still correct.
update_svn ~ \{.bash} #!/bin/bash # update_svn su - puppet -c `cd
/etc/puppet; svn up; cd doc; ../bin/gendoc' ~
The new kernel for the EeePC (2.6.25) has deprecated the
/proc/acpi/battery interface, so I had to write a new script for use
in my own zsh prompt.
The script will work in both 2.6.24 and 2.6.25, so without further ado, here it is. It is written as a function for easy inclusion in any prompts.
#!/bin/zsh
bat() {
PROC=/proc/acpi/battery/BAT0
SYS=/sys/class/power_supply/BAT0/uevent
STATE=
# dc: design capacity, rc: remaining capacity
if [ -f $PROC/info ]
then
STATE=$PROC/state # 2.6.24
dc=$(grep 'last full' < $PROC/info | awk '{ print $4 }')
rc=$(grep 'remaining' < $PROC/state | awk '{ print $3 }')
elif [ -f $SYS ]
then
STATE=$SYS # 2.6.25
dc=$(grep '\<power_SUPPLY_CHARGE_FULL\>' < $SYS | awk -F= '{ print $2 }')
rc=$(grep '\<power_SUPPLY_CHARGE_NOW\>' < $SYS | awk -F= '{ print $2 } ')
else
exit
fi
p=$(echo 3k $rc $dc / 100 \* p | dc )
if grep -iq discharging $STATE
then
printf " %02d" "$p"
else
if [ ${p%.*} -lt 100 ]; then
printf " %02d+" "$p"
fi
fi
}
