How do you say "By then I'll have eaten"
Hola,
How do you say "By then I'll have eaten"?
Is it
Para entonces habré comido
I'm trying to learn to use haber in the future tense and wanted to check if this is correct.
Muchas gracias,
Rangi

Entonces is used as a preposition, not as a pronoun. To play it safe, I would say "Para ese tiempo, habré comido."
But yes, your use of haber is correct. 
What is the tense "I will have eaten by" or "it will have arrived by" ... and how does it look in español with any regular verb?
You use the future tense of "haber" to say "I will have".
He comido -> I have eaten
Habré comido -> I will have eaten
I think you use the conditional, Cuándo llegas habría comido ya = When you arrive I will have eaten. Ammending above to: Cuando llegarás habré comido ya. In two minds though not sure that the first example is incorrect.
