In previous three episodes I explored regular expression APIs of Ruby, Crystal, and Python, so let's finish this by doing the same exercise in Raku. The problem is the same - there's multiple date formats, and we want to extract information from whic...
In previous two episodes I explored regular expression APIs of Ruby, and Crystal, so let's do the same exercise in Python. The problem is the same - there's multiple date formats, and we want to extract information from whichever one matches. I'm doi...
In the previous episode we've taken a look at Ruby Regular Expression API. I want to try a few more languages, and the most obvious one to start with is Crystal. A lot of solutions work exactly like in Ruby, but some of the differences are interestin...
It's easy to check if a string matches a regular expression, it's easy s =~ /rx/. To check if it matches any of multiple regular expressions, it's also really easy - s =~ /rx1|rx2|rx3/. Alternatives are a basic feature of every regular expression eng...
The goal of parsing is turning unstructured text input into some useful data. The most popular parsing system is regular expressions. Unfortunately APIs to integrate regular expression libraries with their host programming languages are stuck in the ...
What gets to be included in languages and what gets pushed into some third party library is a result of history more than reason. For example pretty much every language comes with every possible trigonometric function included and preloaded, so you c...
