Parser

A parser turns its input (often text in form of a file) into a more advantageous representation (usually a certain data structure in memory) to perform a specific task.

Common examples include:

CS-MIC is a .NET library written in C# designed to give developers easy access to expression parsing. For many developers, there is no need to involve complicated settings and formats. With few exposed methods and objects, CS-MIC makes basic expression solving as simple as possible with as little logic required from developers as possible. In fact, one can pull a value with only one line of code.
