Greek characters with perispomeni (tilde) accent were not properly shown
in the output document, because the "textgreek" feature re-defined \~ in
a way incompatible with lgrenc.def since version 0.8 (2013-05-13)
(package greek-fontenc).
The compatibility-definition is required for older versions of the font setup
(before the move of "lgrenc.def" from "babel" to "greek-fontenc").
It is now done with "ProvideTextCommand" to not overwrite the more complete
implementation in lgrenc.def.
With the compatibility definition, combined diacritics with tilde
must be input with the tilde first (e.g. \~>, not \>~).
"unicodesymbols" is changed accordingly.
Also, some LICRs for combining Greek diacritical characters were added to
Unicodesymbols.
This fixes bug #9615.
The "notermination" flag tells LyX, that terminating an LICR macro with {} is
not necessary. This is normally the case for all macros with non-alphabetical
name (e.g. \{).
However, combining diacritical characters are converted to *accent macros*,
which expect an argument (the base character).
In Unicode, the base character precedes the combining character,
in LaTeX the combining character precedes the base character.
LyX changes the order of the two characters to get this right,
e.g. "x" + "combining tilde" becomes "\~{x}".
In the special case there is no preceding character (e.g. at the start of the
document or a paragraph), Unicode shows the combining diacritical character
without base character.
The replacement is currently not "terminated" (e.g. "\~"), because of the
"notermination=text" flags in "unicodesymbols".
The accent macros take the *following* character as base character, which is
clearly not intended.
In case of a paragraph consisting of just one combining diacritical character,
LaTeX compilation fails with an error.
With the patch, LyX writes the accent macros with an empty argument,
e.g. "\~{}", the output is similar to the view in the GUI with the diacritical
character on its own, not on the follwoing character.
This is bug #9612. The patch is from Günter Milde. He wrote:
The patch uses the "long" macro names (\llless and \gggtr) to minimize
name-clash probability. (There is, e.g., a name clash of \lll with Babel's
polish.ldf (cf. bug #6197))
and fix wrong ones. This fixes the safe part of bug #8888. The symbols
provided by mdsymbol.sty have to wait, since mdsymbol.sty provides a huge
number of symbols, I don't have the time right now to process them all, and
a partial file format update does not make sense.
The macro is identical to \ldots in texted, but this way, tex2lyx can import both \ldots (as InsetSpecialChar) and \dots (as unicode glyph), while retaining the original distinction (which might get relevant with some special packages or via user redefinition of one of these macros).
The main part of the fix (unicodesymbols) is from Jürgen. This commit fixes
tree problems:
- \; etc. were also used in text mode, but are math only
- all of those glyphs need to be forced with utf8
- actually, \; etc. are not the correct macros, since the encoded spaces are
breakable, but the math spaces are all protected. The sapce symbols are not
defined in the utf8 encodings.
\textsubtilde is a combining character (0x0330), but 0x02f7 is not.
Apart from the wrong LaTeX output, having the same command for two symbols
confuses texc2lyx.
There were found with -dbg mathed ans entering a math inset.
I kept the AMS versions, except leadsto, which is only an approximation in AMS.
hbar was simply defined twice with identical definitions.
The stmaryrd package adds support for lots of math symbols, using a font
designed to accompany the computer modern fonts. The changes in detail:
- Fix generate_symbols_list.py to work with stmaryrd.sty. It loooks like it
was automatically translated from a perl version and never used.
- Generate the new symbols in lib/symbols using generate_symbols_list.py and
add some manual adjustments
- Generate stmary10.ttf by a simple ttf export from stmary10.sfd with fontforge
- Add license info for stmary10.ttf
- Create a test file with all symbols from stmaryrd.sty. Actually it would be
nice to have this for the other fonts as well.
- The mechanics: lyx2lyx, tex2lyx, font machinery etc.
Math commands need it as well as text commands. At the same time, this
further unifies the checking for termination and fixes cases of wrong
output (e.g. for 0x2005).
- 0x200c is equivalent to \textcompwordmark
- 0x2011 is equivalent to \nobreakdash-
- 0x2009 is a breakable thin space (the old definition was non-breakable)
- 0x202f is a non-breakable thin space
- add spaces 0x2007, 0x2008, 0x200a and 0x200b

The clash can however still happen if those packages are both loaded for other symbols.

Now you can also require a|b|c, and if any of the features is already used,
no other one will be loaded. The first feature wins if none is already used.
This is required for a part of bug #7811.

Essentially, it is not true that Cyrillic characters in math are to be typeset
in italic by default, and LyX already permits to style them as desired.

Cyrillic formatted text in mathmode
If some other letters from some script need to be typeset in italic,
it will suffice adding the flag "mathalpha" to the unicodesymbols file.

- build an exception list of characters that must be output as LaTeX command in any case
(except in utf8-plain). I.e., the utf8 encodings now also honour the "force" flag.
* lib/unicodesymbols:
- add "force" flag to combine characters. Fixes rest of bug 4946.

unicodesymbols file. When the command for a mode is not specified, the
other one is used (taking care that it also works in the "wrong" mode).
This allows to avoid the \lyxmathsym macro when a native math command
is available. Patch from Georg, modifications to the unicodesymbols
file by me.
