ox-latex: default packages cleaning

ox-latex: default packages cleaning

[Rasmus]

[-- Attachment #1: Type: text/plain, Size: 5262 bytes --]

Hi,

We could do some cleaning of org-default-package-alist before Org 8.3.

* tolerance

Why is "\\tolerance=1000" part of org-default-package-alist?  Is this
value good for all languages?  If we keep it, it should be configurable.
But people who explicitly wants this behavior can probably add it
themselves.

If it's a means to archive "high-quality" paragraphs, maybe microtype is
probably the 'proper' fix...

* Fixltx2e

This packages is depreciated with TL2015 cf. LaTeX News 22.  We can use
\RequirePackage[current]{latexrelease} but there's no point in that....
AFAIK latexrelease only useful for backwards compatibility.

* marvosym¹ 

This is used for

     ("EUR" "\\EUR{}" nil "€" "EUR" "EUR" "€")
     ("EURdig" "\\EURdig{}" nil "€" "EUR" "EUR" "€")
     ("EURhv" "\\EURhv{}" nil "€" "EUR" "EUR" "€")
     ("EURcr" "\\EURcr{}" nil "€" "EUR" "EUR" "€")
     ("EURtm" "\\EURtm{}" nil "€" "EUR" "EUR" "€")

We could either call \\texteuro{} or use eurosym.  IMO, if people wants
something more sophisticated than \texteuro (which depends on the current
font) can load marvosym or eurosym.

* Wasysym² 

Wasysym is used for a couple of smileys.

     ("smiley" "\\smiley{}" nil "☺" ":-)" ":-)" "☺")
     ("blacksmile" "\\blacksmiley{}" nil "☻" ":-)" ":-)" "☻")
     ("sad" "\\frownie{}" nil "☹" ":-(" ":-(" "☹")

I don't know why these smileys are blessed when '😱' and '😺' are not.
Ideally, you'd just use unicode smileys, but this requires {xe,lua}tex.
So for now we can could use \(\ddot\smile\) and \(\ddot\frown\) and shave
off the extra dependency.  Put perhaps it's better to just let people
choose themselves which smiley command they will want to use in which case
we could also just remove wasysym.

I would like to second microtype.  In fact as far as I know, now a days
it is recommended to load that for almost all documents with significant
text on TeX.SX.

I would also suggest removing inputenc.  At the moment, it is loaded
with the AUTO option.  AFAIK, this is redundant since most recent
(meaning for quite a few years) TeX engines already use the encoding of
the file if nothing is specified.

The next one would be fontenc, now it is loaded with T1.  I'm not sure
if this is needed.  Maybe LaTeX experts like Marcin or Fabrice could
comment.

Didn't know about this.  Thank you.  I would vote for dropping it.

> * marvosym¹

Agreed.  On top of this, wasysym also interferes with integral symbols
from amsmath[1].

We could also take this opportunity to provide users an easy way to
switch between TeX engines.  I have been using XeLaTeX with Org and
outside for quite a few years now.  Originally what used to be very
hacky, is now simply replacing a couple of packages in the header and
calling xelatex instead of pdflatex.  And the list of packages is pretty
much identical for LuaLaTeX.  This is what I would use:

  \usepackage{fontspec}
  \usepackage{microtype}
  \usepackage{polyglossia}  % instead of babel
  % of course this should be something appropriate for the buffer
  \setdefaultlanguage[variant=british]{english}

So an option like tex-engine:xelatex or tex-engine:lualatex adds the
above to the default packages and the right binaries.  Just an idea.

Cheers,

It's easy enough to add and we should keep the default minimal.  Though
microtype is certainly a package I would not mind imposing on people.

I think you might be right, but I haven't looked into it.

I thought it was needed for some symbols, but it seems it might not be.

No, the manual notes it has comparability with amsmath build it.  It
installs them under \varint and friends.

It's already pretty easy.  I bind org-latex-pdf-process to the desired
engine via latexmk in my file.  I also wrap fontenc and inputenc in
\ifpdftex\else\fi or whatever.  In any case, betterᵀᴹ support for xelatex
would be nice.

You can use babel with xelatex.

Yes, but polyglossia is recommended.  In the interest of minimal work on
the part of Org, this could just be ignored.  I don't think we add babel
anyway, or do we?

I thought we did, but we don't.  Anyway, babel works across different tex
backends which is nice feature.  That was the point.

These two patches goes some of the way towards what you want.
org-latex-pdf-process would also have to patched as well, though.

Test document:

     #+title: test xetex
     #+language: en
     #+options: tex-variant:xetex
     * header
     #+BEGIN_SRC emacs-lisp

                    '("AUTO, french" "polyglossia" nil (luatex xetex)))
     #+END_SRC


Result (node the missing inputenc and fontenc):

Let me know when you find bugs.

I'm trying to think of an elegant way to map from a tex-variant to a
command.  Perhaps change the variant names to the latex variants and input
that.  E.g. if using plain commands, "pdflatex" is changed to replaced
with "xelatex".  texi2dvi uses "LATEX=xelatex texi2dvi".  With latexmk you
can use -pdflatex=xelatex.  Rubber: no clue and it's not part of TL...

I'm in two-minds about this.  On the one had it is a nice thing, but on
the other hand, it prevents the more fine grained control offered by
polyglossia.  For example, I used this in my setup before:

  \setdefaultlanguage[variant=british]{english}

I don't see an easy way of passing the optional argument.  But on the
other hand

  \setmainlanguage{english}

is plain, simple, and works in most (almost all) cases.  I'm thinking
whether to leave the babel/polyglossia features entirely up to the user.
That said, I like the feature very much.  For people who write in
multiple languages, if they load polyglossia, it should "just work" for
all their documents.  Which is great!

WDYT?  What do others think?

It's a shame that Polyglossia is so much different from babel....  For
babel we translate en-gb to "british" which is a valid babel language.
But your example shows that org-latex-babel-language-alist does not work
for polyglossia.  Which means that somebody has to come up with a mapping
from language codes (en-gb) to (language . variant) pairs (your example).

Also, some mechanism needs to be in place to convey random options like
spelling={new, old} for German...  Unless polyglossia options can be set
afterwards via latex_headers.

The only limitation here is whether somebody wants to contribute
org-latex-polyglossia-language-alist (≡ go through the manual and map all
pairs).  Conveying language-specific options in Org is what I worry about.

The attached supports Polyglossia better.  Note, the last loaded language
is the main one (as babel).  Perhaps org-latex-variant-file-string should
be less annoying (not a file-variable).

Test file:

     #+title: test xetex
     #+language: en-gb
     #+latex_variant: xelatex

     * header
       add polyglossia

     #+BEGIN_SRC emacs-lisp
     (add-to-list 'org-latex-packages-alist
                   '("AUTO, french" "polyglossia" nil ("lualatex" "xelatex")))
     #+END_SRC

The polyglossia bits work well.  The file local variable prompt for
every export is quite annoying though.  Same goes for the exported file,
opening it brings up the same prompt again.  I guess it is a one time
thing to mark that variable as safe, then it should be good.  

I have a few other questions:
- how does one change the variant when doing a subtree export?  By
  setting EXPORT_LATEX_VARIANT?
- Is it possible to set a default variant?
- How does one insert a line in the package list which is not
  usepackage.  I guess the normal case is still valid:
  "\\somedirective", but inserting a similar variant specific directive
  isn't possible.

I'm starting to wonder, all these complications, is it really worth it?
What do you think?

It's probably too annoying to default org-latex-variant-file-string to a
file variable.  I find it neat to automatically have AUCTeX pick the right
engine, though.

I worry more about how to allow flags to be transmitted without making it
insecure.  E.g. -shell-escape is one that we'd want to allow for minted.
Perhaps whitelisted flags....  Or just allow arbitrary flags after a latex
command.

It seems to work at least to the point that the right engine is written to
the file:

#+LATEX_VARIANT: xelatex
* pdflatex
:PROPERTIES:
:export_latex_variant: pdflatex
:END:

* lualatex
:PROPERTIES:
:export_latex_variant: lualatex
:END:

org-latex-variant => "pdflatex"

Not possible ATM.  You could use iftex on the latex level or we could
allow something like '("\\mymacro" ("pdflatex")) and enforce the second
argument to be a list to differentiate it from ("PKG OPTIONS" "PKG")....

> I'm starting to wonder, all these complications, is it really worth it?

Most of my longer documents declare the compiler via bind of file
variables.  So I'd use it.  It would also allow me to get rid of some
filters.

FWIW, it seems that people who played with different LaTeX engines used
the "LATEX_CMD" property, as adviced on Worg [1].  Doesn't matter if we
change that, but just a reminder of some already common usage.

I didn't know that worg page.  Just to understand, you are advising to use
"LATEX_CMD" as the keyword name?  FWIW, that's fine with me, though
presently it's not really accurate as only {pdf,xe,lua}latex is allowed
(I'm hesitant to allow arbitrary scripts).

Yes.

AFAIK, it's not intended to do more than just indicating which flavor of
the LaTeX engine to use (and, then, correctly update the real commands
which will be run), that is {pdf,xe,lua}latex.

> (I'm hesitant to allow arbitrary scripts).

I agree. Just stick to the basic need, which is to be able to easily
change of LaTeX engine.

I'd however also like to allow some flags, e.g. -shell-escape/write18 for
minted.  I cannot think of other useful flags.

A colleague of mine were missing her umlaut today cause she hadn't loaded

As I wrote a minute ago, I would rather not add microtype, though it's
a minor thing, really.

Can you elaborate on that?  AFAIK, XeTeX and LuaTeX use UTF-8 by
default, but pdfetex (which is the default LaTeX engine) does not.  And
quite a lot of people ose pdfetex (me included;-)).  I haven't heard
about any heuristic determination of encoding by TeX (and I hope nothing
like that happens, since it could be disastrous).

Thanks for calling me an expert, though I'm not one regarding fonts and
their encodings;-).

With fontenc, the thing is tricky.  I do not know much about other
languages, but you actually can't use LaTeX to typeset texts in Polish
without changing the default LaTeX's font encoding (which is OT1, and it
doesn't support some Polish letters).  (Usually, I do not use fontenc
for that, since there is a specialized package for Polish typesetting.)

I guess that removing fontenc for non-English texts might lead to
erroneous results – at least in case of presence of certain Polish words
(e.g., some names in bibliographies).  I guess we don’t want that.

OTOH, one thing we /might/ want to add is \usepackage{lmodern}.  The
Latin Modern family of fonts is a drop-in replacement for the default
Computer Modern, but with all sorts of accented characters.  Using this
font family has the advantage that accented characters are not build
from letters and accents, but are single glyphs in the font.  AFAIR,
this makes words containing accented letters hyphenatable.  Not a huge
gain, but sometimes may be important (especially in some languages, and
with narrow columns).

At least on Windows/Miktex this isn't working.  And while I don't like
miktex enough people do.

If people have the need for additional fonts they can add it.  In a patch
further down the thread I add support to set backends for packages (so
fontenc is only loaded if using pdflatex).

If you'd replaced lmodern with libertine I would have been more inclined
to agree (though it might not have as wide support as LM).  BTW: I guess
any of the GUST fonts would have pretty great glyph support.

An easy mechanism for changing font package is nice.  E.g. I use libertine
by default, but in some cases I'd might want to use another package in
which case I'd want to have libertine replaced.

Feel free to test the patch in another post.  If's difficult because: (i)
we want to be able to change engines with some liberty, but not to much
(e.g. you can run xelatex but you can't run myrandomscript.sh); (ii) the
info plist is not available at compile time so we have to write the info
to file, in the patch I use the AUCTeX latex-command var; (iii) it would
be nice to support flags (-shell-escape), but see (i).

Leaving this out probably doesn't break texing with older
texlive versions.

Please try to keep export compatible to older versions.  I have a
couple of computers where I can use new versions of org-mode (and an
appropriate version of emacs), where it is not feasible to install a
newer version of texlive.

Best regards

The target of Org 8.3 is 24.3.  I don't know if there's a policy wrt
targeting older versions of auxiliary software.

In the case of fixltx2 it's reasonable to only remove it from the default
packages after the release of Org 8.3.  Extrapolating, users of org-stable
will only see that change 1-2 years from now.

Forget what I said.  You are right.

LaTeX will also work without fixltx2e and org latex export probably
doesn't need it anyway.

Sorry about that.

My suggestion: forget about \tolerance.  It’s low-level TeX stuff,
hardly anybody knows what it does, really (it is one of the dozen or two
parameters governing the line-breaking algorithm), and most people would
not see any difference anyway.  I wouldn’t add microtype, OTOH.  One
reason: it issues a lot of warnings when you use a font it does not
know.  It doesn’t hurt, but some people don’t like warnings.  Also, some
people might not really /want/ microtype – it messes around with font
widths, and even with the default settings (which are rather
conservative), it can look a bit strange.

Didn’t even know that.

My opinion: remove both.
