I am writing a thesis, I have a List of Greek Symbols chapter. The list can be successfully generated, but I found the sequence of greek symbols were not correct. Here is my code:

\documentclass{article}
\usepackage[utf8]{inputenc}


\usepackage[hidelinks]{hyperref} % hyperlinks
\usepackage[toc, nopostdot, nonumberlist, nogroupskip, acronym, order=letter]{glossaries} 

\newglossary[ch1]{greekstyle}{ch2}{ch3}{List of Greek Symbols}

\setglossarystyle{long} % left align
\makeglossaries


\include{glossary_entries} % define all your symbols in a separated file. 


\title{My title}
\author{Name}
\date{November 2020}

\begin{document}

\maketitle

% print all the symbols without referencing them
\glsaddall
% remove the left vacant space of long style

What it generates: prom_fig

But this is not in alphabetical order. For example \Xi should be placed before \Omega . The uppercase order and the lowercase order are both wrong. How can I fix this? Thank you very much.

Here is an easy fix: arrange the Greek letters manually.

One can add a sort argument to the \newglossaryentry{}. I numbered my greek letters in glossary_entries.tex like this:

\newglossaryentry{gls:phi}{name={$\phi_i, \phi_n$},description={basis function, orthogonal basis functions}, sort = {b21}, type=greekstyle}

\newglossaryentry{gls:tau}{name={$\tau$},description={truncation error}, sort = {b19}, type=greekstyle}

...

And changed the command to print glossaries:

\printnoidxglossary[sort=standard, type=greekstyle] 

Then I obtained the desired order.
