Uninstalling all ruby gems

If ever things go south and you get entangled in a mess of conflicting gem dependencies, or if it's just time for a spring cleaning and removing a swarm of outdated gems, you can uninstall all gems from your system by running:

gem list --no-version | xargs gem uninstall -aIx

Rails Installer major update

With the recent release of Ruby 2.0 I took on the long-overdue task of updating my Rails Installer shell script.

This update includes:

  • easier install flow
  • shorter install links
  • leftover garbage removal
  • updated Ubuntu package dependencies
  • tested for compatibility with Ubuntu 12.10 and Mint 14
  • choice of Ruby version to install (1.9.3 or 2.0.0)

Triggering the installer is now easier than ever:

With curl

curl -LO https://github.com/tarakanbg/railsinstaller/raw/master/ruby.sh && bash ruby.sh

With wget

wget --no-check-certificate https://github.com/tarakanbg/railsinstaller/raw/master/ruby.sh && bash ruby.sh

Gems updated for Ruby 2.0 - Part 1

In the wake of the recent Ruby 2.0 release over the last few days I've updated some of my gems for 2.0 compatibility.

This batch includes all of my aviation & vatsim related libraries, except for airdata, which as a rails engine will be updated/tested for compatibility with the Rails 4 / Ruby 2 combo when its time comes.

This being a maintenance release, some minor refactoring changes and dependency updates were also implemented where applicable.

The list of updated gems:

All listed gems still support the Ruby 1.9.3 + versions, however the support for the 1.8.x branch has been dropped with this latest update.

vACC Malta Website

I'm happy to announce the launch of yet another Rails project: the website of vACC Malta.

MaltavACC

Under the hood it features a customized Refinery CMS integration, multiple aviation and vatsim related Ruby libraries, developed by me previously.

On the frontend it's Twitter bootstrap, HTML5/CSS3 compliant, with a nice red/white color scheme (the colors of the Maltese flag).

I wish my friends in Malta good luck with their new vACC and blue skies!

AIRAC 1302 LQSB changes

AIRAC 1302 brought some changes to LQSB FIR and LQSA procedures in particular, introducing STARs, 2 new waypoints, other waypoint changes, 4 new IAFs and a new ILS procedure, transitioning from the new IAFs.

vACCBiH sector files have been updated to reflect those changes and here's the changelog:

v. 1302

Global changes

  • Changed coordinates for waypoints TIMID and NORPI in accordance with AIRAC 1302 and NOTAMs A2668/12 and A0085/13
  • Slightly adjusted coordinates for KEB, KIS VORs to match published navdata
  • Added waypoints: ADNAN, EMKES. Remember to display them via your clients "Display Settings"

LQSA changes

  • All newly published LQSA star diagrams can now be displayed on radar for reference. Tracks are combined where applicable to mimize screen clutter. Check your Display Settings > Stars to enable disable the STAR tracks. Please note that the approach tracks are also depicted as STARS, as the sct file format does not separately support approaches.
  • Added the new ILS S approach and its transitions as a radar diagram (under the STARS section). Please study the chart carefully, as this is perhaps the most important addition of this update, contaning the transitions from the new IAF fixes ADNAN, EMKES, NORPI and TIMID where the new STARs terminate to the localizer 12.
  • All LQSA STAR tracks can now be assigned to pilots via dropdown menu. Interim waypoints in STARs can now be displayed along the route of tagged a/c and used for time prediction, coordination and directs.
  • List of the new LQSA STARs as implemented in the new sector file: BOSN1N, NORP1L, SARA1L, KEB1P, VRAN1M, GILU1P, GILU1L, MOST1L, MOST1P. Easy mnemonics for the new STARs: all "L" STARS terminate at TIMID, all "P" STARs terminate at ADNAN, all "N" STARs terminate at NORPI, all "M" STARs terminate at EMKES

Attributer - Ruby gem for adding width and height attributes to image tags

A new Ruby gem release for adding width and height attributes to image tags within HTML blocks.

This library will parse a piece of HTML, find all the image tags inside it, obtain the width and height of these images and insert them as attributes to the img tag. It will then return the entire HTML with the image attributes properly in place.

Useful for example as a callback with WYSIWYG editors that don't automatically add width and height attributes to images or for instantly optimizing all your old blog or CMS posts with img tag attributes for speed and standards compliance.

Usage

This library augments the default Ruby String class with 1 public method: .image_attributes. You can attach this method to a string variable containing a piece of HTML of any length or complexity. This method takes one of 2 mandatory arguments: (:domain => "http://my-domain.com") or (:path => /my/local/filesystem/path).
It will raise an ArgumentError exception if neither argument is passed.

These arguments are only used to locate the images referenced in your HTML and poll their width and height; they are not written in the resulting HTML: the src attribute of the img tag remains unchanged. Either a full local path or a URL prefix is needed.

For discovery purposes these arguments are concatenated to the src attribute of the image tag, i.e. if your images are accessible via http://my-domain.com/assets/test.jpg and you already have src="/assets/test.jpg" in your image tag, then you only need to use
(:domain => "http://my-domain.com") as an argument.

Likewise if your images are locally accessible via /home/www/site/assets/test.jpg and you already have src="/assets/test.jpg" in your image tag, then you only need to use
(:path => "/home/www/site") as an argument.

The .image_attributes method will return a string of the entire HTML block with the image attributes properly in place.

Examples

html = '<img alt="test" class="gallery" src="/assets/test.jpg">'
html.image_attributes(:domain => "http://my-domain.com") 
  # => '<img alt="test" class="gallery" src="/assets/test.jpg" width="200" height="266">'

html = '<img alt="test2" class="fuzzy" src="/images/test2.jpg">'
html.image_attributes(:path => "/home/www/site") 
  # => '<img alt="test2" class="fuzzy" src="/images/test2.jpg" width="340" height="155">'

html = Post.find(20).body # =>
