== Dashing ==  
http://shopify.github.io/dashing/


URL: http://shopify.github.io/dashing/
It's a pretty slick dashboard... wish it was perl... but who creates fluff in perl
== Requirements ==
* Tested on Debian GNU/Linux 6.0 - Squeeze (dreamplug)
* NodeJS
* Ruby 1.9
* Git




Line 30: Line 21:




==== Ruby additional steps ====
=== Other steps ===
* Install bundler gem ( I didn't have it, safe to run if you aleady have it)
<source>
<source<
ln -s /var/lib/gems/1.9.1/bin/dashing /usr/bin/
gem install bundler
</source>
</source>
* Link all the binaries. We shouldn't have to do this since we used apt-get to install.. but whatever.
: This will allow you to run ruby, bundle, dashing, etc.. '''anytime you install a NEW gem, you might want to run this'''
<source>
<source>
for f in /var/lib/gems/1.9.1/bin/*
gem install bundler
do
ln -s /var/lib/gems/1.9.1/bin/dashing /usr/bin/
filename=$(basename $f);
if [ -e $filename ]
then echo "$filename already exits";
else sudo ln -s $f $filename;
fi
done
</source>
</source>




=== Install NodeJS ===

; INSTALL from apt-get
<source>
apt-get install nodejs

* none of the source/compiling worked for me...

; This is a step normally not documented, but required for the arm7 (dreamplug)
 
* modify file: '''node-vx.x/deps/v8/SConstruct'''
* You need to add '''-march=armv7-a'''
 
<source>
# You need to edit this file and modify
# line # 84 it should look like this:
'gcc': {
    'all': {
      'CCFLAGS':      ['$DIALECTFLAGS', '$WARNINGFLAGS', '-march=armv7-a'],
      'CXXFLAGS':    ['-fno-rtti', '-fno-exceptions'],
    },
</source>
 
 
* Finish the compiling and install
 
<source>
# Configure seems not to find libssl by default so we give it an explicit pointer.
# Configure seems not to find libssl by default so we give it an explicit pointer.
./configure --openssl-libpath=/usr/lib/ssl

<source>
<source>
gem install dashing
gem install dashing
</source>
</source>
* '''remeber the script before''' -- we need to link the new installed gem '''dashing''' into /usr/bin/
<source>
for f in /var/lib/gems/1.9.1/bin/*
do
filename=$(basename $f);
if [ -e $filename ]
then echo "$filename already exits";
else sudo ln -s $f $filename;

=== Dashing Options ===
 
 
==== Server Port ====
* Dashing runs on Thin behind the scenes. That means that any config for running thin works. Example:
<source>
dashing start -p 5000 -e production
</source>
 
 
* Run in the background
<source>
dashing start -d
</source>
