Google Gemini

• To use the extension, you need a Google Gemini API key. You can register for one at https://aistudio.google.com/app/api-keys.

Installation

With composer

composer req in2code/texter

Main configuration

After that, you have to set some initial configuration in Extension Manager configuration:

Title	Default value	Description
promptPrefix	-	Prefix text that should be always added to the prompt at the beginning
apiKey	-	Google Gemini API key. You can let this value empty and simply use ENV_VAR "GOOGLE_API_KEY" instead if you want to use CI pipelines for this setting

Note: It's recommended to use ENV vars for in2code/imager instead of saving the API-Key in Extension Manager configuration

GOOGLE_API_KEY=your_api_key_from_google

RTE configuration

Per default, in2code/texter sets a default RTE configuration via Page TSConfig:

RTE.default.preset = texter

If you want to overrule this default setting, you can require in2code/texter in your sitepackage (to ensure that your extension is loaded after texter) and define a different default preset. Check file Texter.yaml for an example how to add texter to your RTE configuration.

Hint You can also use texter for selected RTE fields in backend. Example Page TSConfig:

RTE.config.tt_content.bodytext.preset = texter
RTE.config.tx_news_domain_model_news.bodytext.preset = texter
