Small Ruby CLI Improvements (Part 2): Wirb!

January 2011, ruby · gem · irb · working-environment · regex · ripl

Many people use irb with wirble. I also did.

I’ve been quite happy with it, but sometimes I noted that some symbols were displayed as : without the symbol name (e.g. in method name arrays) and that the representation of regexes looked quite strange.

This is why I’ve looked at the wirble tokenizer, fixed some bugs, liked it, extended it and created Wirb. These are the improvements:

Organise your code comments with rake notes:todo!

November 2009, rails · hints · working-environment · regex · rake

Lots of IDEs (e.g. Netbeans) and some editors (e.g. gedit with plugins) have a nice feature: They show comments, which start with something like TODO or FIXME. Those annotations are quickly written and they make it harder to forget some things you wanted to (or have to) do.

I have just discovered that Rails has this feature already built-in!
