I did not notice that all icons in math/ are shared and in a0895046 I have
overwritten some of them. I am restoring them in the proper subdir.
Two of them, namely font.svgz and frac.svgz, give warnings that should
be addressed. Anyway, I see that these icons use fonts. They are better
substitued with paths (a menu entry in inkscape) because if the fonts
are missing on a system, the icons look different and, in general, they
may look ugly.
You have to manually delete the lib/images/svg directory as git
tracks only files.
There may be warnings on the terminal due to some faulty icons that have
to be found and corrected. Moreover, some of the icons are not rendered
too well at the default size. These ones should be properly tweaked.
Kudos to Jürgen for putting together such a large number of icons.
Most of the changes are related with dictionaries returning views instead of
lists.
xrange -> range (since xrange is gone in python 3)
The code that is special to support both python 2 and 3 is enclosed in a comment
\# Provide support for both python 2 and 3
and
\# End of code to support for both python 2 and 3
And so later it can be removed safely when python 2 is no longer supported.
We have some math macros that exist only because LyX can display them easily,
but which require user preamble code. These commands should not appear in
autocompletion, they are only there to make the formulas of users who actually
need thgese symbols and know what to put into the preamble more beautiful.
The svg files produced by vector editors may end up containing a lot
of unused elements that increase their size without any impact on
quality. For example, this occurs when copy/pasting between images
such that unused effects or shadings simply clutter the files.
Removing these elements in some cases may reduce the size to one half
or one third of the original one, leaving unmodified the image quality.
I also tweaked some existing icons to make them look better at default size.
Moreover, some text was replaced with paths, because the required font may
not exist on a system and font substitution would take place, making the
icons look different on different systems.
Both the hyphen and special phrase conversion did not exclude insets which
reference external files. This was wrong since LyX does not replace
\SpecialCharNoPassThru etc for these insets.
Previously, LyX did replace some words with typeset logos, and there was no
way to prvent this except putting them, in ERT (bug #4752). Now we have
special insets for these words, and standard text is left alone.
Thanks to Scott for testing. Command insets do not use InsetText for the
arguments, so users have to write them in LaTeX syntax (this is bug #4595).
Therefore we must leave hyphens alone in these insets.
Previously, consecutive dashes in .lyx files were combined to endash and emdash
in some cases, and in other cases they were output as is. This made the code
complicated, and resulted in inconsitencies ((bug #3647).
Now, a dash in a .lyx file is always a dash in the output, for all flavours.
The special handling is moved to the input side, so that you still get an
endash if you type two hyphens. If needed, this can be changed or made
customizable without the need to update the file format again. Many thanks
for the fruitful mailing list dicsussion, which contributed significantly to
the final version.
I am also replacing some existing icons with reworked ones that
look better at small sizes. I think that these icons are now
comparable to the png ones as regards quality at the default size.
