[Tex/LaTex] How to activate on LaTeX greek and latin characters

Question

I try to use LaTeX writing paper Greek and English text, without using separate commands for Greek or English (like: \begin{otherlanguage}{greek}), but using both Greek and Latin characters under the same command.

I found the auto-greek package but I did't manage to install it on my macbook.

\usepackage{auto-greek}

Note that I have every font that supports Greek and Latin characters!

Answer 1

Use can write Greek directly with the alphabeta package.

\documentclass {article}
\usepackage [utf8]           {inputenc}
\usepackage [greek, english] {babel}
\usepackage                  {alphabeta}

\begin {document}

Text in Greek: τίνι ἢ  γὰρ, ἄμφω

\end {document}
