Re: Drag & Drop not working in 2.1.0 (Uwe?)

I'm happy to report that the file drag & drop (from an explorer to lyx) is working with 2.1.1 in Windows 8.1 64bit.

Unfortunately this info is shown for development builds only :(

Perhaps you can get this information from the Qt dll files?

Making the preview log more accessible

At present if you want to consult the preview log -- for instance, if 
you open a document and equations etc. are not snapping into their 
preview appearance -- you need to navigate to the temporary directory 
where LyX does its work and locate the log there. The log will generally 
pinpoint where the previewing is coming unstuck. It would be good to 
have this log more readily available. The obvious place is as another 
tab in the View > Messages pane.

For every new equation or preview inset, or modification of a previous 
one, a new log is created. To keep tabs for all of them would be 
excessive, so I imagine only the latest would be shown.

NextNoIndent After Theorems, Etc

We set NextNoIndent 1 after Theorems, etc, but a Standard paragraph 
after a Theorem is indented. I thought I'd fixed this for 2.1.x, but 
apparently not. Any objection if I do fix it?

layout combo box height

If you start a new document and do alt + p and type "address", the
combo box is not tall enough to display all of the results (so a
scrollbox is displayed). Similarly if you type "paragraph". I can
provide screenshots if others are unable to reproduce.

The attached patch fixes the above problem but creates other problems
(extra space if you delete characters in the filter) and is clearly
not the right thing to do, I was just experimenting and thought maybe
this can help get an idea of what's going on.

Can others reproduce?
Does anyone have an idea for a correct fix?

showing a "not built with spellchecker enabled" message?

If LyX is not built explicitly enabling a spellchecker, some fields
are greyed out. This comes up from time to time on the list. Would it
be more or less confusing to have a message explaining that LyX needs
to have the option set at compile time?

[PATCH] Include locale.h for setlocale(3).

Commit 82faa6619239c2e57fba9128899bafe29d728e51 added some calls to
setlocale(3) but did not include locale.h. The implicit include is added
on some platforms, but not others, such as FreeBSD with libc++.

LyX Qt 5 issues

It seems that switching to Qt 5 is still a bit away, but planning
early is always a good idea. I would like to start (if it exists
already, please let me know) either a wiki page or a trac issue
keeping track of issues that we think have to do with Qt 4 vs. Qt 5.
Hopefully for each issue related to LyX with Qt 5 we can list the
versions of Qt 5 and OS's for which we have confirmation the issue

It would be nice to not just list the bugs that switching to Qt 5
would bring, but also the fixes or elimination of workarounds that the
switch would bring.

Any thoughts on this?

[ANNOUNCE] LyX 2.1.1

Public release of LyX version 2.1.1

We are proud to announce the release of LyX 2.1.1.  This is the first
maintenance release in the 2.1.x series.

LyX is a document processor that encourages an approach to writing based
on the structure of your documents and not simply their appearance. It is
released under a Free and Open Source Software license.

You can download LyX 2.1.1 from

LyX 2.1.1 is the result of on-going efforts to make our stable version
even more reliable and stable. We have fixed a number of bugs and made
a number of improvements. These are detailed below. We strongly encourage
all LyX users to upgrade to this version.

Several users have reported seemingly random crashes with 2.1.0, sometimes
resulting in dataloss. These crashes appear to happen when the user 
to save a file, and the dataloss occurs because the original LyX file is 
written by a corrupt file that then cannot be opened. The seemingly random
crashes, we believe, are due to auto-save, which is enabled or disabled in
Tools> Preferences> Document Handling > "Backup documents every...minutes".

Unfortunately, we have been unable to find the cause of this bug, though all
known reports seem to involve documents that contain tables, and the 
file always ends with: \begin_inset Tabular.

To prevent dataloss, we have changed the way LyX saves files if the user
has not enabled backups. LyX now renames the existing file before
attempting to save the new one (in effect, making a temporary backup).
Then, if the save fails, the original file can be restored.

If you think you have found a bug in LyX 2.1.1, either e-mail the LyX
developers' mailing list (lyx-devel <at> or open a bug
report at

If you have trouble using LyX or have a question, consult the
documentation that comes with LyX and the LyX wiki, which lives at If you can't find the answer there, e-mail the LyX
users' list (lyx-users at

We hope you enjoy using LyX 2.1.1.

The LyX team.

What's new

** Updates:


- We now flush the output stream more frequently, as a temporary measure
   to help us gather information about the crash mentioned above.

- To prevent dataloss, we have changed the way LyX saves files if the user
   has not enabled backups. LyX now renames the existing file before
   attempting to save the new one (in effect, making a temporary backup).
   Then, if the save fails, the original file can be restored.


- Updated Chinese (simplified), French, Interlingua, Japanese, Spanish,
   Swedish and Ukrainian user interface localizations.

- updated French translation of the User Guide and the Math manual.

** Bug fixes:


- Fix assertion when selecting in document with bi-directional text (bug 

- Fix assertion when accepting change (bug 9145).

- Honor the NextNoIndent layout parameter also in the exported output.

We have fixed several significant issues involving conversion of 2.0 
format into
2.1 format, and conversely. This mostly affects the new argument insets 
and, in
particular, beamer documents. These are detailed below.

- Fix conversion of beamer block titles ending with non-ERT insets to 
2.1 format.

- Fix conversion of beamer blocks with preceding or trailing blanks.

- Add \justification parameter when converting to 2.1 format (avoids
   warning when converting back to 2.0 format).

- Fix conversion of argument insets from 2.1 to 2.0 format.

- Fix "use math package" settings conversion from 2.1 to 2.0 format.

- Fix "use math package" settings conversion from 2.0 to 2.1 format (bug 

- Fix table cell rotation conversion from 2.1 to 2.0 format.

- Fix import of some argument insets.

   dialog is open (bug 7685).

[URGENT] Unable to Commit to lyx-www via SVN

While trying to do the 2.1.1 release, I have found that I am suddenly 
unable to commit to the lyx-www subversion repo. It keeps asking me for 
a password.

I have tried this from two machines, and neither works.

If I understand correctly, it seems like another feature would be that
cygwin users could have Sumatra's inverse search automatically
configured (related to your Wiki edit [1]).

I haven't heard from Vincent or Uwe. I wonder what Peter (CC'ing now)
thinks of bundling Sumatra on Windows.

[PATCH] LyX HiDPI support in OS X with Qt 5


LyX has been lacking HiDPI ("retina") support for a while now and I
decided to tackle this project. It has been listed as a GSoC 2013
potential project [1], so I assume there's enough interest in it.

I worked on a patch which adds basic 2x DPI drawing support for text
and graphics. Math formulas and inline images also work (except the
splash screen) but the UI icons would require creating higher res

Comparison (LyX 2.1.0 with Qt4 vs LyX git with Qt5):

Qt added HiDPI support in version 5 [2], but I think it's not yet
fully functional. I say this because I ran into a problem where
partial viewport updates (namely the cursor and preedit strings) are
rendered incorrectly. It seems that it wrongly uses non-scaled pixels
dimensions which displays viewport contents from half the requested
coordinates, but I'm not sure it is a Qt bug. To workaround this
(second patch)  I used full viewport updates only, but this can
degrade performance. I would appreciate some help on this issue as I'm
not experienced with Qt.

I haven't tested this on Linux or Windows but to compile for Qt 5 on
OS X I used some additional steps from [3].

I am also new to LyX development and I am willing to improve this
patch, so any feedback will be welcome.
