How to change the English fonts in Elegantbook ?

[ZhangWay1024]

First of all, the Elegantbook template is so awesome in all ways, but somehow I just want to use some other English fonts in my book, such as 'EBGaramond'. I also used \usepackage{ebgaramond} in my code, but it did not work. Thus I want ask is there any way to achive my goal?

We use newtxtext package for (pdf)latex compiler, and in newtxtext.sty, there is an \AtEndPreamble patch:

\AtEndPreamble{%
...
  \renewcommand*{\rmdefault}{ntx\ntx@figurealign%
  \ntx@figurestyle}
...
}

So the font settings of ebgaramond package are overwritten, and then the text font won't be set to ebgaramond.

How To Fix

1. You can use xelatex to compile your document, in this case ebgaramond's \setmainfont overwrites newtxtext's;
2. Accroding to https://tex.stackexchange.com/a/39418/180617, you can use

\makeatletter
\@namedef{ver@newtxtext.sty}{9999/12/31}
\makeatother

before \documentclass[...]{elegantbook}, which is saying

\makeatletter
\@namedef{ver@newtxtext.sty}{9999/12/31}
\makeatother
\documentclass[11pt]{elegantbook}
\usepackage{ebgaramond}
...

Maybe we should add a cls option that allows authors to define English fonts themselves, behaving like chinesefont=none? @EthanDeng
