Document Classes ⇒ How to save the preamble to load it in any new script

[tuerkas]

Hello.

Working in: TexMaker

I have an elaborated preamble wih a few many newcommands and document's set.
I would like to save my preamble to just load it by command when I open a new file to don't have to copy (Ctrl.+C) and paste (Ctrl+V) every single time I need to work with.

I have tried customed Orders but goes like this:

Code: Select all

\begin{[All the preamble]}
 \end{[all the preamble again]}

.

Does anyone have a solution?
Thanks for your attention

Hi Tuerkas,

save it as a .tex file, such as preamble.tex, and in your document just write

Code: Select all

\input{preamble}

Here is an example, where I use \input for the preamble, and \include for chapters. (\include is a different thing, designed for chapters and the like, with page break): https://latexguide.org/chapter-11
