I'm writing a document using the copernicus_discussions.cls document class. This document class doesn't work when using babel. So I need to keep LyX from automatically using babel. However, even though in Tools->Preferences->Language I selected "Language package: None" and disabled all checkboxes on that page, and even though in my document preferences, I selected "Language package: None", the generated LaTeX source still contains the line


How can I prevent LyX from inserting that line?

  • What's wrong with using babel with natbib? – Joseph Wright Sep 27 '12 at 16:52
  • as I wrote in the question, the copernicus_discussions.cls class doesn't work in conjunction with both natbib and babel. More specifically, LaTeX gets sent into an infinite loop at the first \citet or \citep command. – andreas-h Sep 27 '12 at 17:18
  • I just realized it also happens when using \cite, so it's not natbib dependant – andreas-h Sep 28 '12 at 8:15

    There used to be a Lyx mailinglist, some years ago I got a usefull answer there, my question then also aimed at Lyx internals. – Keks Dose Sep 28 '12 at 9:34
  • Links to LyX mailing lists are found at lyx.org/MailingLists – Torbjørn T. Sep 28 '12 at 11:13

This is a known bug that will be fixed with LyX 2.0.5

Workaround: In Document Settings (Language), set language package to Custom and insert % dummy (or anything else preceded by a % char) into the custom package input widget.

  • Confirmed, the same still exists in LyX 2.2.3 (2017-05-17) – sitilge Oct 16 '17 at 12:55
  • @sitilge I have LyX 2.2.3 as well, and that bug does not appear here. Setting the "Language Package" to "None" removes babel from the preamble. – Torbjørn T. Oct 16 '17 at 15:14
