ExampleExtension

Every time Textractor has a sentence of text ready, it will call OnNewSentence on all extensions it finds sequentially, plugging the output of OnNewSentence from the previous extension into the next extension.
After the sentence has been processed by all extensions, it will be displayed.

SentenceInfo

The following properties are in SentenceInfo

"current select": always 0 unless the sentence is in the text thread selected by the user.
"process id": process id that the sentence is coming from. 0 for console and clipboard.
"text number": number of the current text thread. Counts up one by one as text threads are created. 0 for console, 1 for clipboard.
"text name": pointer to start of a wchar array of the name of the current text thread.
"void (*AddSentence)(void* this, int64_t number, const wchar_t* sentence)": pointer to function that adds a sentence to the text thread with the specified number.
"this": context pointer used for aforementioned function.
