What is the best way to debug Typoscript in TYPO3 CMS?

Question

What is the best way to debug typoscript in the TYPO3 CMS?

Assuming I have a list, which is not displayed - what is the strategy to look for the issue?

Answer 1

The most important thing is, not to rely on code you found via google. Have a look into TSref and check what is possible.

Just some little additions which are easy to overlook (IMHO):

• The template analyser has an option: "View the complete TS Listing", so can search in the whole created typoscript! Including conditions.
• TS Object Browser: you can check conditions to simulate different situations

If you need to debug TypoScript configuration in the backend, go to the "Info"-Modul, select a page in the page tree and then select "Page TSconfig" in the main window. There you will get a info about Page TS Config.

These system extensions are usually installed, but they can be deactivated:

• tstemplate
• tstemplate_ceditor
• tstemplate_info
• tstemplate_objbrowser
• tstemplate_analyzer
• info_pagetsconfig (info modul)
• tsconfig_help (addition to the info modul)

It may happen, that someone else just deactivated them.
