This is from branch "features/chat3"
I was/am trying to adapt cmake, but I have difficulties to compile 
src/support/FileMonitor.cpp with the gcc6.2 compiler.
There are many warnings because of std::auto_ptr declared in our boost source
boost/boost/smart_ptr/shared_ptr.hpp:459:22: warning: ‘template 
class std::auto_ptr’ is deprecated
shared_ptr( std::auto_ptr && r ): px(r.get()), pn()
and also in gcc6.2 include
.../gcc6.2/include/c++/6.2.0/bits/unique_ptr.h:49
template class auto_ptr;

The real trouble starts with
src/support/strfwd.h:55:9: error: reference to ‘basic_string’ is 
ambiguous
typedef basic_string 
string;
src/support/strfwd.h:54:64: note: candidates are: template class std::basic_string
template class 
basic_string;

Indeed, it happened :-)! Just a quick note that all attendees raised their hands 
when asked about familiarity with LaTeX, but only one of them knew LyX already 
(positive experience of a thesis written with LyX). Despite this, I wasn't 
assaulted & destroyed by LaTeX geeks as I was expecting :-)...

I ended up with making an overview of LyX features, +/- following those few 
slides I circulated already

  http://retis.sssup.it/~tommaso/LinuxDay-2016.pdf

I made a live demonstration of:
- LyX maths & tables editing
- graphics insertion including easy creation of .odg graphics from samples 
(local patch) and .gnuplot scripts/plots automatically graph-ed (local patch)
- advanced find & replace, including finding styles with regexps and finding 
maths
- LyX chat (local patch) through the use of a local XMPP server on my laptop
- and a few other things.

[more or less, all things included in my tommaso repo, linux-day-2016 branch, 
perhaps I'll polish and push something else tomorrow]

Got a couple of students asking off-line some more details about external 
scripting similar to what I had shown with .gnuplot :-)!

So, let's hope to get some more users and/or contributors :-)!

Cheers,

If anyone else is curious why fonts-lyx seems to be so much more popular
than LyX, it seems to be because the firefox package 'suggests' it, at
least on Ubuntu.

A useful tool is:

  apt-cache rdepends fonts-lyx

Re: LinuxDay @ Pisa - Oct 22nd

[Helge Hafting]

LyX features important for me:

* LyX don't "mess up" formatting. (indents, blank lines, lists,...) When 
writing some pages for my students, I don't really need to check output 
because it all just works. Everytime.  I can also write down what 
happens at a meeting in real time, and mail out a PDF as the meeting 
ends. LyX never put a heading on the bottom of a page either. Cross 
references and TOC is always correct. (Apparently, a more expensive word 
processor struggles with just that. Users need to 'update the TOC' or 
whatever?)


* LyX can typeset straight margins with good hyphenation, without 
getting excessively long spaces between words. This alone is a good 
reason for using LyX. Ragged-right looks unprofessional, and so does 
lines with excessive interword space.


* LyX is very good for multi-file documents! Example: I have a file with 
a chapter describing "network firewalls using linux". This is included 
into a larger document about network security. It is also used in 
another document about securing linux servers. These two documents have 
different length and different number of chapters. So the firewall 
chapter may be chapter 3 on page 14 in one case, and it may be chapter 2 
on page 7 in the other case. There are no problems with this. The TOC, 
the page & figure numbers, everything works in both cases! So if I add 
another section to my "firewall" document, there is only one place to 
edit. There is no effort keeping the other two documents 'in sync'; 
because there are no copies to synchronize.


* Another multi-file case: I teach programming. So I need source code 
examples. I can embed references to source code files in LyX. Again, 
there is only one place to edit - the source code file. When LyX 
produces a PDF, it reads the source code files and typesets it - 
complete with syntax highlighting! And no effort keeping the compilable 
source code 'in sync' with the document. No code is copied into LyX, 
only a reference to the filename.


* LyX can use just about any LaTeX feature. But I don't need to use 
LaTeX commands for everyday writing, it is as easy as any other word 
processor.


* LyX supports my language well, and lots of others too. Both the user 
interface, hyphenation and spellchecking. Commercial word processors 
have less support for 'small' languages.


* LyX does presentations as well as text document; so I don't need 
powerpoint. I wouldn't know how to get something like a tikz animation 
in powerpoint anyway.


Other cool features:
* Excellent math support. Any formula of interest can be written in LyX. 
It won't be hard, and it will look good. Thanks to the LaTeX backend, of 
course. Lyx will also interface with math software; press a button and 
it will do difficult integrals for you, by asking maxima or mathematica.


* LyX cooperates with Lilypond, so you can have both music and text set 
nicely.

Hi Tommaso,


1) Distinctive and decisive features of LyX (at least for me):

* Change tracking for collaborative authorship, or even just for
  suggesting corrections to someone writing in LyX.
  * Anyone who had to suggest corrections to a co-author or student, or
received such suggestions, knows the pain of going from e-mail/print
back to the editor window and checking that everything was taken
into account (on either people's side). Change tracking keeps track
of everything in a single location.
  * It is a complement of, not a rival to, version control systems.
There is a good synergy with git in my experience.

  This is a “how did we do before this?”-feature. All the rest below are
  more a matter of personal habit. But having and making use of change
  tracking in any collaboration, or of some alternative I have yet to
  hear of (Word and Google Docs being excluded in an academic context),
  is a matter a professionalism.


* Semantic edition of math equations:
  * Selections/copy-paste that respects the boundaries (i.e. no chasing
of closing braces, etc.)
  * Semantic edition of grids (array, align environment).
Easily add/delete/swap rows/columns. Example of copy row (Alt+M W
C) to quickly perform lines of calculation.
  * Typing LaTeX commands with the keyboard together with
auto-completion and immediate notice of typos (best of both
worlds).
  * Math macros (with different display in PDF and in LyX).

  All these make LyX not just a tool for the final step of writing
  a paper/dissertation: it can entirely serve as a notebook. I think
  this can clear up some misconceptions about LyX in more LaTeX-oriented
  communities.


2) Some things that did not work so well before and work much better in
LyX 2.2, and which are easy to show:

* Instant preview of math (in fact the SVG/LaTeX integration that was
  posted recently in combination with the preview inset would make a
  good demo: the picture uses the surrounding font and font style, and
  instant preview reflects the changes in real time).

* Code preview which follows the cursor.

* Hi-DPI thanks to Qt5, and kerning/ligatures on screen (important for
  Hebrew or Arabic, Jean-Marc surely knows more about this).


3) Other than that, basics, of course:
* No fingerpainting of text styles
* Nice PDF output, LyX takes care of all compilation steps
* Bibliography browser
* Cross-references (copy/paste label as reference)
* Outliner


It's also useful to say that LyX has many bugs and quirks, but that we
use it (and like it) anyway, for lack of anything that comes close to
it. (My own experience, again.)


Best,
Guillaume
