* Code Zauker: your code, indexed
Code Zauker is a search engine for programming languages.
Code Zauker is based from ideas taken by old Google Code Search and uses Redis as storage engine.

For news and discussion: http://gioorgi.com/tag/code-zauker/


* INSTALL
To install Code Zauker,simply issue
#+BEGIN_SRC sh
  gem install code_zauker
#+END_SRC
You need also [[http://redis.io/][redis-2.4.6]] or better. 
For a sample redis configuration see the etc/ directory of the project

* Try it out
** To index all your files
The following command will index all the code file below /full_path_of_sources/ providing 
a feedback on standard output
#+BEGIN_SRC sh
 czindexer -v /full_path_of_sources/
#+END_SRC
If your redis server is on another machine, you can use the following command
#+BEGIN_SRC sh
 czindexer --redis-server myredisserver  -v /full_path_of_sources/
#+END_SRC
Also authentication over redis is supported:
#+BEGIN_SRC sh
 czindexer --redis-server password@rediserverpwp  -v /full_path_of_sources/
#+END_SRC


To search for the 'my_beautiful_method' try out:
#+BEGIN_SRC sh
 czsearch  my_beautiful_method
#+END_SRC

Looking case insensitive can be userful too....
#+BEGIN_SRC sh
 czsearch -i  'Select USER_id'
#+END_SRC

Tip:Take a look to czindex and czsearch commands help for full options list
** Web interface
There is a new shiny web interface based on sinatra. To try it out, fire
#+BEGIN_SRC sh
 ./bin/webgui
#+END_SRC
It is still beta, but it is *very* fast, thank to redis!


** Parallel execution
If you want to speed up indexing, you can use the mczindexer command.
For instance:
mczindexer eclipse-sources/
will fire at most 10 parallel czindexer.

** Simple stats
You can ask code zauker to print a nice stats on standard output.
Run
#+BEGIN_SRC sh
 ./bin/report.rb
#+END_SRC
and enjoy!

* Aws tests
** Micro instance
Without multiplexing you get
 real    4m39.599s
for indexing code_zauker

With
 time find . -type f -print0 | xargs -0 -P 10  -n 20  ./bin/czindexer -v --redis-server awsserver
You get about
  real    0m31.284s


* DEVELOPING
For developing with Code Zauker you need bundler 1.0.21 or above
