We experienced problems with Sunspot and Solr on Tomcat: Umlauts (ä, ö, ü) were not correctly handled on Tomcat while everything was okay on the local development machines (your local Sunspot service you start with the sunspot:solr:run task is based on Jetty).

We use a stemmer that reduces "Sänger" to "sang" and "Sanger" to "sang" as well.
Though, results for "Sänger" where empty on Tomcat.

This is due to a UTF-8 bug in RSolr (see Github for some discussion on that).
The bug is fixed in a ...

You can now add code blocks without indentation, by using triple-backticks:

```
Code block goes here.

When deploying code with Capistrano (depending on your configuration) at some point Capistrano tries to check out code from your repository. In order to do so, Capistrano connects to your repository server from the application server you're deploying to with SSH. For this connection you can use two SSH keys:

• the user's ~/.ssh/id_rsa [default]
• the very same key you used for connecting to the application server - forwarded automatically to the git repository.

If you prefer the second way, add this to deploy.rb:

ssh_options[:forwar...

To access files from another branch or past commit without doing a complete checkout, you can either use

git show branch:file
git show commit:file

to display, or check out the file into your working directory with

git checkout branch -- file
git checkout commit -- file

Sometimes it might be helpful to have a version history for a gem, e.g. when you want to see if there is a newer Rails 2 version of your currently used gem.

At first you should search your gem at RubyGems. Example: will_paginate version history.

The "Tags" tab at GitHub might be helpful as well.

If your git index for some reason becomes invalid, no need to worry.

Your index is corrupt when you see this error running usual git commands like git pull, git status, etc.:

error: bad index file sha1 signature
fatal: index file corrupt

Though it sounds bad, your changes are still there. Fix it by first removing the index file, then resetting the branch:

rm .git/index
git reset

You should be all good now.

To be safe, make a backup of .git/index before you delete it.

Some helpers for poking around at your Capybara driven browser's cookies in integration tests.

Supports Capybara's bundled drivers (rack-test, Selenium Webdriver), and adapters for other drivers may be added.

ProgressBar is a simple Ruby library for displaying progress of long-running tasks on the console. It is intended to be as simple to use as possible.

If you want to move a complete commit from one repository to another (and you don't want to add it as a remote), you can use these steps:

Create a patch

In the source repository, create a patch based on the commit by running

git format-patch SHA1_OF_COMMIT~..SHA1_OF_COMMIT # Note the ~
git format-patch HEAD~ # Shortcut for the latest commit

This will create a .patch file that describes this commit.

Apply the patch

In the target repository, restore the commit from the patch file with

gi...

Saying git diff only shows unstaged changes relative to the index (or HEAD if the index is empty, alternatively any hash or branch you supplied) but leaves out files you already staged for the next commit.

To diff your added changes with HEAD, say:

git diff --cached

Effectively, this gives you the changes you will commit when you run git commit without the -a switch.

This describes all the steps you'll need to get Solr up and running for your project using the Sunspot gem.

Prepare Sunspot on your development machine

What you want in your Gemfile:

gem 'sunspot_rails'
gem 'sunspot_solr'
gem 'progress_bar' # for sunspot:solr:reindex

Now define what should be indexed within Solr from your ActiveRecord models, e.g.,

class Article << ActiveRecord::Base

  searchable do
    text :title
 ...

Gem to get Rails 3's new ActiveRecord query interface (where, order) and the new scope syntax (chaining scope definitions) in Rails 2.

You also get #to_sql for scopes.

Gem to get Ruby 1.9 features in Ruby 1.8.

Code coverage for Ruby 1.9 with a powerful configuration library and automatic merging of coverage across test suites.

Note that rcov won't ever have support for Ruby 1.9, you're supposed to use rcov for 1.8 and simplecov for 1.9.

Let's say you have commits that change a file (and looking at the commit details show you the changes, etc). Now, when you do a git log you see them, but when you say git log that.file these commits don't show up? This is for you.

The reason is that the file got deleted deleted/re-added/renamed (any or all of those).

Instead of ...

git log master -- some.file

... you need to say:

git log --follow master -- some.file

Then your commits will show up.

Note that tig also understands --follow.

Kudos to Julien...

Removing features and merging those changes back can be painful. Here is how it worked for me.\
tl;dr: Before merging back: reinstate reverted features in a temporary branch, then merge that branch.

Scenario

Consider your team has been working on several features in a branch, made many changes over time and thus several commits for each feature.\
Now your client wants you to deploy while there are still stories that were rejected previously and can't be deployed.

I have no idea how it's supposed to work (or why the don't have a print CSS), but this works for pages written with Markdown:

1. "Edit" the wiki page
2. Copy all text
3. Run a Markdown interpreter and pipe its result, e.g.: kramdown > /tmp/github.html
4. Paste your markdown
5. Press Ctrl-D to finalize your input
6. Open the generated HTML file and print it.

Our gitpt script to generate git commits from Pivotal Tracker stories has been tweaked and polished and is now part of the geordi gem.

Install the freshly released version 0.7 now:

gem install geordi

This update will bring you commit with an initial "setup wizard" (that asks for your PT API key and initials) and prettier output: stories are colored by their state and thos...

ExpandAnimations is a LibreOffice/OpenOffice.org Impress extension to expand presentation animations before exporting to PDF. This way the exported PDF will have one page per animation stage.

Ruby bindings for Sundown, a fast and full-featured Markdown parser that lets you define renders for arbitrary output formats.

Framework to write command-line apps in Ruby. Comes with a nice way of processing parameter options, some utility classes and Cucumber steps for testing your CLI app.

Git has a built-in repository viewer for your web browser. a bit similar (but less awesome) than github.

If you have apache installed, simply go to your repository, and enter
git instaweb --httpd apache2
otherwise, simply install lighttpd and just run
git instaweb

This should open a brower automatically pointing to your repository. If not, try to connect to localhost:1234.

You can stop the server with
git instaweb --stop

How to ignore new files

Globally

Add the path(s) to your file(s) which you would like to ignore to your .gitignore file (and commit them). These file entries will also apply to others checking out the repo.

Locally

Add the path(s) to your file(s) which you would like to ignore to your .git/info/exclude file. These file entries will only apply to your local working copy.

How to ignore changed files (temporarily)
