Introduction:
I am going to attempt to document programs I have written most are unaware of that are under the hood of virtually all Ultimate Edition operating systems. Software I have released to the internet are licensed under GPL feel free to edit / re-write anything I have released to date as you see fit. This particular page I am going to write about the ultimate-edition-code-cleanup package.
These programs can be accessed from the command-line interface (CLI). The programs from the ultimate-edition-code-cleanup package are written in BASH & Ruby, however I am fluent in many languages. I am unsure if that is the way to word that statment when talking about programming languages
The above links will extend as I write pages based on each package I have written for Ultimate Edition. I am sure I have at the very least 10 pages to write similar to this one covering various tools and languages. I do want to start by pointing out one that is visible, however goes totally unnoticed by most people.Bash-Script-Maker:
- Script maker Gedit plugin also a part of ultimate-edition-code-cleanup deb
The above Gedit plugin will generate a bash script skelaton if you will to get you started writing scripts, this suits 2 purposes:
1. To get you started writing your script instantly saving hours of time.
2. Education (a great place for newbs to learn bash scripting)
I have considered extending this to include a wizard like interface injecting commonly used functions. Wow am I lazy when it comes to coding right? No, I try to live by the rule why re-create the wheel. It would also accelerate application development.
CODE CLEANUP:
Back to the CLI. I'm going to start with my personal favorite code-cleanup it is written in Ruby. Why my favorite? No-one is perfect & I am a sloppy programmer. I do not bother indenting etc. This tool not only makes your code look pretty it will point out errors. These errors are displayed as indentions. If you write software in bash this tool is absolutly a must have. I am first going to provide an example of code with errors before and after the tool has ran across it. The below is bogus code, chroot detection should be done from udev and / or checking against inode 2. Beyond the scope of this post.
Before:
#!/bin/bash
#Ultimate Edition Customizations preinst for Ultimate Edition 3.7
set -e
IUSER=${SUDO_USER:-$USER}
IHOME="/home/$IUSER"
case "$1" in
configure)
echo "Checking for chroot environment."
if [ $IUSER != 'root' ]; then
echo "No chroot environment detected, removing."
abort-remove
echo "Done."
else
echo 'Root user / chroot environment detected.'
if test -f /etc/skel/examples.desktop; then
rm -R /etc/skel/examples.desktop
fi
if test -f /root/.bash_history; then
rm -f /root/.bash_history
fi
echo "VERSION Detected: $version"
if [ -n "$version" ] \

Error: indent/outdent mismatch: 1.
theemahn@JackHammer:~/Music/ultimate-edition-customizations-3.7_all/DEBIAN$
This means a done or fi etc. is missing somewhere in the code where the indention is missing is typically where the error lies let's examine the code. This board does not handle tabs very well lets look at a screenshot.

Bash-Depends:
It does not end there, there is also bash-depends in this same package. Bash depends will scan a bash script looking for dependancies in the bash script so you can add the list to your control file for deployment. I guess the main reason I wrote this app beyond wanting to make my debs perfect; I was told it could not be done in bash
Let's run bash-depends against conky-builder(another program I wrote):

Please wait this may take a while depending on the size of the script.
