Changing the font of greek letters of mathastext

Question

I'm using the mathastext package to make math contents consist with the text. The package offers a \MTgreekfont command to change the font of greek letters. Current I use the lmtt font but its size does not match that of Courier, thus I would like to switch to the one native to Courier. However I cannot find the internal name of Courier (like lmtt for Latin Modern), \MTgreekfont{courier} does not work. How can I find this internal name? Or, is there a way to change the scale of current greek letters?

Moreover, what if I use Menlo font with xelatex? The font itself apparently offers greek letters, How could I use them with mathastext?

Below is a MWE.

%! TEX program = xelatex
\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage{courierten}% Courier
% \usepackage[no-math]{fontspec}% These two lines require xelatex
% \setmonofont[Mapping=tex-text]{Menlo}% Menlo
\renewcommand{\familydefault}{\ttdefault}
\usepackage[italic,LGRgreek]{mathastext}
\MTgreekfont{lmtt} % What should I put here respectively, for Courier and Menlo?
\Mathastext
\begin{document}
\noindent Text\\
$\alpha\beta\gamma\epsilon$
\end{document}

Answer 1

Solution, using pdflatex and mathastext. On my Linux system with texlive, I found the LGR font files with the command find texlive -name "*LGR*fd" (texlive is in my home directory), and then one can find the font names.

\documentclass{article}
\usepackage{courierten} % CourierOneZeroPitch-TLF
\usepackage[italic,LGRgreek]{mathastext}
\newcommand{\mtset}[1]{\MTfamily{#1}\MTgreekfont{#1}\Mathastext[#1]}
\mtset{Cochineal-TLF}
\mtset{CourierOneZeroPitch-TLF}
\mtset{DejaVuSans-TLF}
\mtset{EBGaramond-TLF}
\mtset{TheanoDidot-TLF}
\mtset{TheanoOldStyle-TLF}
\mtset{lmtt}
% Switches font
\newcommand{\mtv}{\MTversion}
% Creates row in tabular
\newcommand{\mtrow}[1]{\mtv{#1} #1:
  &\quad\mtv{#1}$\alpha$&\mtv{#1}$\beta$&\mtv{#1}$\gamma$&\mtv{#1}$\delta$
  &\mtv{#1}$\epsilon$&\mtv{#1}$\zeta$&\mtv{#1}$\eta$&\mtv{#1}$\theta$
  &\mtv{#1}$\iota$&\mtv{#1}$\kappa$&\mtv{#1}$\lambda$&\mtv{#1}$\mu$
  &\mtv{#1}$\nu$&\mtv{#1}$\xi$&\mtv{#1}$\pi$&\mtv{#1}$\rho$
  &\mtv{#1}$\sigma$&\mtv{#1}$\tau$&\mtv{#1}$\upsilon$&\mtv{#1}$\phi$
  &\mtv{#1}$\chi$&\mtv{#1}$\psi$&\mtv{#1}$\omega$\[2mm]
}
\begin{document}
\mtv{CourierOneZeroPitch-TLF} CourierOneZeroPitch-TLF is default
tt-font in the question's setup but it has no greek alphabet\medskip
\setlength{\tabcolsep}{0mm}
\begin{tabular}[t]{rccccccccccccccccccccccc}
  \hline\
  \mtrow{Cochineal-TLF}
  \mtrow{CourierOneZeroPitch-TLF}
  \mtrow{DejaVuSans-TLF}
  \mtrow{EBGaramond-TLF}
  \mtrow{TheanoDidot-TLF}
  \mtrow{TheanoOldStyle-TLF}
  \mtrow{lmtt}
  \hline
\end{tabular}
\medskip
\mtv{CourierOneZeroPitch-TLF} A little courier with its math
$\displaystyle\frac{\alpha\beta}{2}\int_0^1 f(x)dx$
\mtv{CourierOneZeroPitch-TLF} A little courier \MTversion*{lmtt} with
lmtt's math $\displaystyle\frac{\alpha\beta}{2}\int_0^1 f(x)dx$
\mtv{lmtt} A little lmtt with its math
$\displaystyle\frac{\alpha\beta}{2}\int_0^1 f(x)dx $
\end{document}

Many interesting and beautiful greek fonts that I could find in texlive on my system.

If you're using XeLaTeX, you can declare the Greek letters to use the main font (assuming it contains them).

documentclass[11pt,a4paper]{article}
\usepackage[no-math]{fontspec}% These two lines require xelatex
\usepackage[italic]{mathastext}
\setmonofont{Menlo}
\renewcommand{\familydefault}{\ttdefault}
\Mathastext
\Umathchardef\alpha="0 \symmtletterfont α \Umathchardef\beta="0 \symmtletterfontβ
\Umathchardef\gamma="0 \symmtletterfont γ \Umathchardef\epsilon="0 \symmtletterfontε
\begin{document}
Text $x\alpha\beta\gamma\epsilon$
\end{document}

Fill in the rest.

Answer 3

Your options are:

• Load an OpenType math font with unicode-math, in LuaLaTeX or XeLaTeX. All of them come with Greek alphabets. You can change its Greek alphabet with \setmathfont[Scale=MatchLowercase, range=it/{Greek,greek}]{Some Greek Italic Font}, etc.
• Load \setmathsfont(Greek} in mathspec in XeTeX.
• Load a legacy 8-bit font in the LGR encoding, using mathastext. You generally want to look for a file named lgr*.fd. if you don’t care about keeping the fixed width, you might pair the Greek Font Society’s GFS Neohellenic.
• Load \usepackage{gfsneohellenicot} in PDFTeX to get GFS Neohellenic Math, then use \usepackage{mathastext} to change the Latin letters to Courier/Cursor.
• Load a legacy OML math font, containing both Greek and Latin letters, with isomath or \DeclareMathAlphabet.

Answer 4

To address the original problem, perhaps rescaling courier will do the job: use courier for math but, since it doesn't have its own greek, use lmtt's greek. In my opinion, lmtt's math looks better than couriers because of its use of italics instead of just slanted, so use courier with lmtt math.

\documentclass{article}
\usepackage[scale=0.95]{courierten} % CourierOneZeroPitch-TLF
\usepackage[italic,LGRgreek]{mathastext}
\MTfamily{CourierOneZeroPitch-TLF}
\Mathastext[courier]
\MTfamily{CourierOneZeroPitch-TLF}
\MTgreekfont{lmtt}
\Mathastext[courierlmtt]
\MTfamily{lmtt}
\MTgreekfont{lmtt}
\Mathastext[lmtt]
% Switches font
\newcommand{\mtv}{\MTversion}
\begin{document}
\mtv{courier} Here is a \emph{\textbf{little courier}} with its math
but doesn't have its own greek so I think it gets cmr's
$\displaystyle\frac{\alpha\beta\gamma\delta}{2}\int_0^1

\mtv{courierlmtt} Here is a \textbf{\emph{little courier}} with lmtt's
