typo3 read configuration options in typoscript

Question

I've tried several approaches to read the configuration options of my plugin in typoscript, but none of them seem to work

    ajax.30 = TEXT
    ajax.30.value =   {plugin.tx_parser.settings.numVar}
    ajax.40 < {tx_parser.settings.numVar}
    ajax.50 < {tx_parser.settings.numVar}
    ajax.80 = TEXT
    ajax.80.value = {options.numVar}
    ajax.90 = TEXT
    ajax.90.value = {settings.numVar}

Can anyone please explain me the syntax or post a link where it is explained; I can use ext_conf_template.txt explained here https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ExtensionArchitecture/ConfigurationOptions/Index.html but I didn't get these options in typoscript.

All I want is to access (in typoscript) the configuration options of the following picture

If I browse Constants I don't see any of these options

If I add my plugin to the site I see some plugin options but none of them I wanted

Configuration added to the Extension configuration are not the same thing as TypoScript constants. And if you add an Extension Configuration option it will not be added to TypoScript as a constant. --- All constants have to be defined in your template record either in the constants field, or by using static files and include them in your template record. — Nitori

You can use constants with this syntax in TypoScript setup or constants

var = {$plugin.tx_parser.settings.numVar}

So in your case:

ajax.30 = TEXT
ajax.30.value = {$plugin.tx_parser.settings.numVar}

See https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/UsingSetting/Constants.html

To assign an earlier declared setup value you would use the < (object copy) operator

ajax.30 = TEXT
ajax.30.value < plugin.tx_parser.settings.numVar

Here is an on overview of its syntax: https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/TypoScriptSyntax/Syntax/TypoScriptSyntax.html

The difference between constants and setup is essential. You can check in the backend in the module Template -> Template browser - see https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/UsingSetting/Debugging.html
