Page Layout ⇒ Fancyhdr with a KOMA-scipt class

[Cham]

I'm using the fancyhdr package to modify the header and footer of several KOMA-script classes (scrbook, scrartcl, scrreprt). Everything compiles fine and the output is really nice. I'm only getting a single warning in the console (shown below).

However, I know it's not recommended to use fancyhdr with a KOMA class document since the KOMA classes already have built-in features to modify the header and footer. So I have two questions :

1. What are the wrong things that could happen or what should I expect if I still use the fancyhdr package with a KOMA class document ?

2. What should be the proper code to replace the fancyhdr code shown below, if I really have to scrap that package ?

Code: Select all

Here's the warning I get :

Class scrartcl Warning: Usage of package `fancyhdr' together
(scrartcl) with a KOMA-Script class is not recommended.
(scrartcl) I'd suggest to use
(scrartcl) package `scrlayer-scrpage'.
(scrartcl) Nevertheless, using requested
(scrartcl) package `fancyhdr' on input line 9.

So how should I replace the fancyhdr code ?

[Johannes_B]

Just keep on. Your system is outdated anyway.

Code: Select all

Looking at the KOMA-script manual would have helped you.

[Cham]

What do you mean by "Your system is outdated anyway." ? Could you be more specific?

[Johannes_B]

You have TeX Live 2015 installed. There have been many updates to LaTeX and contributed packages. The nag warning about fancyhdr is only there, because fancyhdr wasn't updated yet. scrlayer-scrpage should be in a solid state by TL 2015, but i am not sure.
LaTeX itself, the basic LEGO set, was updated in the meantime.

By the way, did this help you at all?

[Cham]

This is why I'm changing the fancyhdr code to the KOMA version, in my KOMA-script templates. (it's all working great, by the way).

I'm now getting a last strange message in the console :

Class scrreprt Warning: \float@addtolists detected!
(scrreprt) Implementation of \float@addtolist became
(scrreprt) deprecated in KOMA-Script v3.01 2008/11/14 and
(scrreprt) has been replaced by several more flexible
(scrreprt) features of package `tocbasic`.
(scrreprt) Since Version 3.12 support for deprecated
(scrreprt) \float@addtolist interface has been
(scrreprt) restricted to only some of the KOMA-Script
(scrreprt) features and been removed from others.
(scrreprt) Loading of package `scrhack' may help to
(scrreprt) avoid this warning, if you are using a
(scrreprt) a package that still implements the
(scrreprt) deprecated \float@addtolist interface .

How should I interpret that? What is causing that, and is there something to fix? How?

EDIT :

By the way, did this help you at all?

Thanks for the link. Do you consider fancyhdr as an obsolete package?

[Johannes_B]

Try loading package scrhack.

Fancyhdr is not obsolete, it is just not recommended with KOMA-script.

[Cham]

scrhack is one such mysterious package to me ! The documentation I've found is pretty obscure/weird to me! (it's even almost insulting to some packages authors!)

It removes the curious message I've shown above from my console, and the whole compiled document stays the same. What is the purpose of that esoteric package? I'm afraid it's a kind of superfluous "hack" (scrhack = script hack) !

[Johannes_B]

While LaTeX evolved over the years, some packages didn't speed up. scrhack makes some extra LEGO brick sets compatible to LaTeX itself or KOMA-script.
The package exists, because some package maintainers never made an update becuase of various reasons.

[Stefan Kottwitz]

The KOMA-Script author is often a bit harsh.

Via the scrhack package, he ensures compatibility and avoids issues with other packages. Consider it as a service for KOMA-Script users.
