 Detect the correct version of python at runtime and store the result
 for later calls. The check is only performed on the major version
 number, such as to avoid using python 3.

 I don't know why, but when i try to click on tools-perfences alert window

Raw guess: somewhere (not sure where) you preferences were changed to point to a
nonexisting bind file (the bind file maps key combinations to commands), or
alternatively the preferences are correct and the bind file was somehow deleted.

What I would suggest is to (1) make sure that the cua.bind file (I think is the
installation default) is present (in /usr/share/lyx/bind on Linux, typically
C:\Program Files\something like LyX\bind on Windows), and then with LyX not
running (2) delete your home directory (usually ~/.lyx on Linux, maybe
C:\Documents and Settings\you\lyx20 on Win XP, maybe
C:\Users\you\AppData\Roaming\LyX2.0 on Windows 7) and start LyX.  LyX will
reconstruct the home directory.  Note that step (2) deletes all customizations
you did, so if you have custom layouts, menu files etc. stored in your home
directory you'll want to back them up first.

Bounding box for pstricks graphics with LyX

[Andrew Parsloe]

LyX 2.0.2 with its View other formatsPDF(ps2pdf) allows a LyX document 
with pstricks graphics to be compiled to pdf. That's a plus over LyX 
1.6.10. But it has also come at a cost. In LyX 1.6.10 (and earlier 
versions) I could create a document containing only an ERT inset and 
pstricks code like so:


\begin{TeXtoEPS}
\pspicture*(4,3)
\pspolygon(.5,.5)(3.5,.5)(.5,2.5)
\endpspicture
\end{TeXtoEPS}

Provided the preamble included

\usepackage{pstricks}
\usepackage{pst-eps}

this would compile with the View PS button to a postscript graphic 
contained in a bounding box of just a few centimetres per side. In LyX 
2.0.2 the pst-eps package and its TeXtoEPS environment seem to be 
ignored. The graphic compiles okay but the bounding box is now the whole 
page.


It would be very nice, developers, if the 1.6.10 behaviour could be 
restored (without losing the ps2pdf ability of course). I've found it 
extremely valuable to be able to create postscript graphics in LyX like 
this which are no bigger than they need to be. I realise I can crop a 
whole page graphic (in IrfanView for instance) to its natural size, 
but this should really be done at source, as is possbile with 1.6.10.

Not exactly an answer to your question, but this may help you [1]: a
humble attempt to add 'standalone equation editor' capabilities in
LyX. The method allows to generate cropped EPS and PDF documents
containing just about anything that LyX can output.

RE: Patch for lyx.org PayPal donate call

[Scott Kostyshak]

Comments? Can others reproduce?

From: Scott Kostyshak
Sent: Monday, December 12, 2011 3:40 AM
To: lyx-devel@lists.lyx.org
Subject: Patch for lyx.org PayPal donate call

The donate PayPal button, accessed on http://www.lyx.org/Donate gave me a 
PayPal page in Norwegian. I don't know if others will be able to reproduce this 
because I think that PayPal tries to find out your language. If it fails to, I 
guess it defaults to the language of the destination of the payment. I would 
suggest this patch for all of the languages that lyx.org supports. The list of 
countries and their codes that should be passed to PayPal are located here: 
https://cms.paypal.com/us/cgi-bin/?cmd=_render-contentcontent_ID=developer/e_howto_api_nvp_country_codes

For English, the current html code for the PayPal call is
form method=post action=https://www.paypal.com/cgi-bin/webscr;
p
input type=hidden value=_xclick name=cmd
input type=hidden value=donati...@lyx.org name=business
input type=hidden value=Optional Note name=cn
input type=hidden value=EUR name=currency_code
input type=image alt=Make payments with PayPal - it's fast, free and 
secure! name=submit src=https://www.paypal.com/images/x-click-but04.gif;
/p
/form

I propose adding the following line:
input type=hidden value=US name=lc

so that the complete PayPal call would be
form method=post action=https://www.paypal.com/cgi-bin/webscr;
p
input type=hidden value=_xclick name=cmd
input type=hidden value=donati...@lyx.org name=business
input type=hidden value=Optional Note name=cn
input type=hidden value=EUR name=currency_code
input type=hidden value=US name=lc
input type=image alt=Make payments with PayPal - it's fast, free and 
secure! name=submit src=https://www.paypal.com/images/x-click-but04.gif;
/p
/form

Re: problem in LYX

Raw guess: somewhere (not sure where) you preferences were changed to point to a
nonexisting bind file (the bind file maps key combinations to commands), or
alternatively the preferences are correct and the bind file was somehow deleted.

What I would suggest is to (1) make sure that the cua.bind file (I think is the
installation default) is present (in /usr/share/lyx/bind on Linux, typically
C:\Program Files\\bind on Windows), and then with LyX not
running (2) delete your home directory (usually ~/.lyx on Linux, maybe
C:\Documents and Settings\\lyx20 on Win XP, maybe
C:\Users\\AppData\Roaming\LyX2.0 on Windows 7) and start LyX.  LyX will
reconstruct the home directory.  Note that step (2) deletes all customizations
you did, so if you have custom layouts, menu files etc. stored in your home
directory you'll want to back them up first.

Bounding box for pstricks graphics with LyX

[Andrew Parsloe]

LyX 2.0.2 with its View other formats>PDF(ps2pdf) allows a LyX document 
with pstricks graphics to be compiled to pdf. That's a plus over LyX 
1.6.10. But it has also come at a cost. In LyX 1.6.10 (and earlier 
versions) I could create a document containing only an ERT inset and 
pstricks code like so:


\begin{TeXtoEPS}
\pspicture*(4,3)
\pspolygon(.5,.5)(3.5,.5)(.5,2.5)
\endpspicture
\end{TeXtoEPS}

Provided the preamble included

\usepackage{pstricks}
\usepackage{pst-eps}

this would compile with the View PS button to a postscript graphic 
contained in a bounding box of just a few centimetres per side. In LyX 
2.0.2 the pst-eps package and its TeXtoEPS environment seem to be 
ignored. The graphic compiles okay but the bounding box is now the whole 
page.


It would be very nice, developers, if the 1.6.10 behaviour could be 
restored (without losing the ps2pdf ability of course). I've found it 
extremely valuable to be able to create postscript graphics in LyX like 
this which are no bigger than they need to be. I realise I can crop a 
whole page graphic (in IrfanView for instance) to its "natural" size, 
but this should really be done at source, as is possbile with 1.6.10.

Not exactly an answer to your question, but this may help you [1]: a
humble attempt to add 'standalone equation editor' capabilities in
LyX. The method allows to generate cropped EPS and PDF documents
containing just about anything that LyX can output.

RE: Patch for lyx.org PayPal donate call

[Scott Kostyshak]

Comments? Can others reproduce?

Subject: Patch for lyx.org PayPal donate call

The donate PayPal button, accessed on http://www.lyx.org/Donate gave me a 
PayPal page in Norwegian. I don't know if others will be able to reproduce this 
because I think that PayPal tries to find out your language. If it fails to, I 
guess it defaults to the language of the destination of the payment. I would 
suggest this patch for all of the languages that lyx.org supports. The list of 
countries and their codes that should be passed to PayPal are located here: 
https://cms.paypal.com/us/cgi-bin/?cmd=_render-content_ID=developer/e_howto_api_nvp_country_codes

For English, the current html code for the PayPal call is
https://www.paypal.com/cgi-bin/webscr;>

I propose adding the following line:


so that the complete PayPal call would be
https://www.paypal.com/cgi-bin/webscr;>
