New Csv extension

[schulle4u]

A new extension is available for testing: CSV file parser. It loads a CSV file (comma-separated value), and outputs the result as simple HTML table. Following features are available:

• Simple shortcut to load a CSV file.
• Looks for CSV files in downloads directory (configurable).
• Specify the column delimiter (semicolon, comma, tab), globally or per shortcut.
• Use first row as table header by default.
• Styling support for individual HTML table.
• Uses standard PHP functions, no external libraries.

A few things are still on my to-do list, e.g. a search filter for large CSVs, and propper handling of BOM characters in some files. Basic usage however should work stable for the moment. I needed this extension for a personal Wiki project. Building it probably took way more time than preparing the CSVs as Markdown tables, but I personally don't like the Markdown table syntax, especially when handling larger datasets. Oh and last but not least it of course was fun to code this. :)

The Csv extension has been added to the experimental features in the official extensions repository. Latest version contains a table filter, column sorting and bug fixes.
