Showcase: Resume & Portfolio application using Sinatra

Posted by niwo – April 17, 2010

Over the last few weeks a played around with the lightweight Ruby web framework Sinatra to build a resume and project-portfolio application.

The resulting application is still in a early stage but already serves it’s purpose. If you are interested you can check out the code on GitHub or take a look at my resume page.

At the moment the application has the following features:

  • support for resume, contact details and project-portfolio
  • multi language support (using r18n)
  • easy configuration over YAML files for data storage
  • edit your resumes using markdown (using rdiscount)
  • page caching (using rack-cache)

By the way, to get started with Sinatra I can recommend the excellent screencast from Peepcode.

RVM on OSX Snow Leopard & readline errors

Posted by niwo – March 19, 2010

There seems to be an issue with the system readline utility which prevents Rubies installed by rvm from being compiled. A possible fix to this is to install your own version of readline.

Errors in the make log:

readline.c: In function ‘username_completion_proc_call’:
readline.c:730: error: ‘username_completion_function’ undeclared (first use in this function)
readline.c:730: error: (Each undeclared identifier is reported only once
readline.c:730: error: for each function it appears in.)
make[1]: *** [readline.o] Error 1

Your own readline

Compile and install your own readline:

curl -O ftp://ftp.gnu.org/gnu/readline/readline-6.1.tar.gz
tar xzvf readline-6.1.tar.gz
cd readline-6.1
./configure --prefix=/usr/local
make
sudo make install
cd ..

Give rvm another try …

First you have to remove Ruby versions you tried to compile before:

rvm remove 1.9.1

The following command with a reference to the newly installed newline should do the job:

rvm install 1.9.1 -C --with-readline-dir=/usr/local/
