A basic class like Length should not depend on something from
frontend.
This change allows to remove several dummy implementations of
theFontMetrics().
At some time it seemed like a good idea in breakRow() to return early
when the row was bound to be empty. It turns out that this creates two
symptoms:
* empty paragraphs will not have an end of paragraph marker
* since row width is not correctly computed in this case, caret ghosts
can appear in master.
This commit removes the oprimization and replace the do {} while()
construct to a straightforward while() {}.
Related to bug #10952.
It is not good for a support function to depend of anything outside of
it, especially Application.
Here the boolean that indicates that export should be canceled is put
in Systemcall. This allows to remove all the dummy theApp() function
that have been added here and there for linking needs.
Remove warnings for issues fixed in lyx2lyx.
Update the GUI name of the ligature-dash Option.
Fix example for preventing unwanted line break in French.
lyx2lyx erroneousely merged -- to en dash in text with logical
markup "code".
Revealed by recent (but now silenced) ctest fails.
Also add space around en dash in examples.
Ligating of -- to en dashes occure also in teletype fonts.
With some 8-bit fonts, em and en dashes are not copied
exported from the PDF (but this is not limited to dashes in teletype).
With LatinModern, PDF export works fine
MWE:
\documentclass[]{article}
%\usepackage{lmodern}
\usepackage[T1]{fontenc}
\begin{document}
Hallo \texttt{Welt --Welt ---Welt}
Hallo Welt --Welt ---Welt
This gives a more consistent indication of what belongs to an environment
(and semantically, such paragraphs are synonymous to nested standard
paragraphs)
Addresses part of #9261.
