Question

How can I learn how to create LaTeX styles?

The normal way when creating a LaTeX document is to start with something like.

\documentclass[a4paper]{report}
\documentclass[a4paper]{article}
\documentclass[a4paper]{letter}

And that seems to call a .cls (and a .sty) file like letter.cls,
that is controlling the actual layout of the document.

Is there a good way to learn how to create this type of “latex style files”?
Has someone created a howto, step-by-step or simply a good manual on the topic?

Thanks
Johan

I guess that tex.stackexchange.com is the answer on how to continue learning LaTeX.

Answer 1

There are two good papers in the PracTeX journal:

• Minutes in Less Than Hours: Using LaTeX Resources by Jim Hefferon,
• Rolling your own Document Class by Peter Flynn.

A very useful resource is LATEX2e for class and package writers.
