Sure, here are some examples of how parser combinators are used in practice to parse different types of inputs:

* **Parsing JSON:** JSON is a popular data format that is used to represent data in a text-based format. Parser combinators can be used to parse JSON data by combining parsers for individual JSON tokens, such as strings, numbers, and arrays.
* **Parsing regular expressions:** Regular expressions are a powerful tool for matching patterns in text. Parser combinators can be used to parse regular expressions by combining parsers for individual regular expression characters.
* **Parsing natural language:** Natural language is a complex and challenging domain to parse, but parser combinators can be used to build parsers for natural language by combining parsers for individual words, phrases, and grammatical structures.

Here are some specific examples of parser combinators that are used to parse these different types of inputs:

* **The `text` parser:** The `text` parser takes a string as input and returns a parser that matches the input string exactly. This parser can be used to parse individual JSON tokens, regular expression characters, or words in natural language.
* **The `char` parser:** The `char` parser takes a character as input and returns a parser that matches the input character exactly. This parser can be used to parse individual characters in strings, regular expressions, or natural language.
* **The `seq` parser:** The `seq` parser takes two parsers as input and returns a parser that matches the input if the first parser matches and the second parser matches the remaining input. This parser can be used to combine parsers for individual tokens into parsers for larger structures, such as JSON objects or natural language sentences.

These are just a few examples of how parser combinators can be used to parse different types of inputs. There are many other parser combinators that can be used for specific tasks, and the specific combinators that are used will depend on the specific input that is being parsed.
