#272 Alignment of tables and equations at ampersand

[Anonymous]

It would be very helpful when TeXstudio could align content of math and table environments to the ampersand character (&) so that you can overview your content much better.

[Tim Hoffmann]

This feature has already been implemented recently. You may compile the SVN yourself, if you want to use it now, or wait for the next release.

Thank you for your tip.
I compiled the SVN (sadly without poppler, couldn't find out where to add which paths) and it worked quite nice.

Though it has problems with \multicolumn (doesn't detect it as left-out ampersands) and \intertext{} (acts as the first cell and ends the algorithm) and it could be improved when it wraps lines.

When will the next (SVN) release be?

[Tim Hoffmann]

The alignment code is still under development. The lack of correct handling of multicolumns is known and will be addressed. Thanks for the remark on \intertext.
Could you give details what you mean by the improvement of line wrapping.

Building with poppler: which OS?

We currently do not have fixed release schedules, neither for the relase version nor for SVN snapshots. The relase depends on features added and has to be suffieciently tested and stable. So it can strongly vary with the time we've available. The SVN snapshots are just an additional service and will appear now and then.

Poppler: Win7 64bit
The wiki article helps a little bit. But do I have to compile some poppler things first? Or which paths do I have to add to what?
A precise step by step guide would help a lot because I never used Qt but would like to use/test SVN releases.

Line Wrapping: It probably was just the mixture of multicolumns/intertext commands and some very long commands in the cell that produced the bad line wrapping. It does look good after I remove those culprits.

By the way (I'm still using the code fetched a week ago.):
Commented lines get processed, too. This could be a good feature if an author does comment his columns but produces the same results like \intertext.

There are probably more commands like [short]intertext that are allowed in an &-environment but break the algorithm. Maybe a customizable list of ignored commands could be a solution.

Actually, you don't have to compile poppler itself on windows. This should work from scratch:

1. Download and install QtSDK
2. Checkout the SVN
3. Open .pro file in QtCreator (you will be asked to specify build targets: defaults are ok)
4. Compile once. The build is not completed and you will get messages "[somthing].dll: no such file or directory". But the advantage is that the Build directory is created (e.g. "texstudio-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Debug"). Alteratively you may create it by hand (location can be found in the build settings of the project).
5. Copy all dlls from a texstudio installation to the build folder.
6. Compile again.

Thank you for your response.

So far texstudio is working after copying all dlls to the build folder an re-compiling. What is not working is the pdf preview. It crashs when I am trying to use the (internal) pdf viewer.

Following http://sourceforge.net/apps/mediawiki/texstudio/index.php?title=CompileTXS I need to use poppler as well to use the internal pdf viewer.
That's the reason I asked about poppler and some paths.

After starting TeXstudio from Qt it performs something like a self test and produces following errors:
FAIL! : SmallUsefulFunctionsTest::nextWord_simple(citation2) '(lr.word)==(outWord)' returned FALSE. (equal failed: got "abcdef" !=expected " Hallo:Welt! " )
FAIL! : LatexCompleterTest::simple(simple) '(ist)==(text)' returned FALSE. (equal failed: got ">>\abstractname<<" !=expected ">>\abstractname{}<<" )
..\texstudio\tests\latexcompleter_t.cpp(284) : failure location

I now have configured it to work with SumatraPDF.
But I still have to start Qt Creator to run the texstudio.exe. When I start it without Qt it asks for a QtCored4.dll which apparently has something to do with Qt.

[Tim Hoffmann]

PDF viewer crash: There is a known problem with the internal PDF viewer and Qt 4.8.x under windows. I suggest that you use 4.7.4 until this is fixed. For more details see
http://sourceforge.net/tracker/?func=detail&aid=3487550&group_id=250595&atid=1126426

Failed test: Do you use the most recent svn version? I think, something like this has been fixed recently.

QtCored4.dll: That's because you created a debug build. This needs the debug versions of the Qt libraries. To run it stand alone, you should create a realase build. Don't forget forget the 'release' parameter to make (see wiki).
