### Open File problem

Dear LyXers, My wife has LyX 2.1.1 under OS X 10.9.5 (Mavericks). When she tries to open a file, LyX pops a new LyX document up, which is immediately closed. No Open File dialog is shown. The same happens with New From Template. Is there a way to diagnose (and fix) this problem? Is it related to the Yosemite problems arising left and right? I wouldn't like to upgrade to Yosemite and thus to 2.1.1.2, unless it would be totally unavoidably, as remote user support is not my strong feature, and she would be left in dire straits. Thanks in advance. Regards, - Julio Rojas jcredbe...@gmail.com

### On screen math fonts

Hi. I recently upgraded my LyX install to 2.1.2.1 on Mac OS X Mavericks, and I noticed that the on-screen character for \otimes is now rendered incorrectly as an A with umlaut, although the PDF output is correct. I haven't noticed this with any other symbols so far. Is this a bug, or some configuration issue? Thanks. -- Ernesto Posse Zeligsoft.com

### Re: On screen math fonts

I can confirm this, also in 2.1.2.2. I also have had the problem with a one other symbol, but now I don't remember which.

### Calculyx

I've written a LaTeX package called calculyx which numerically evaluates mathematical expressions in LyX before one's eyes using instant preview. It is written in the expl3 language of LaTeX3 but is used just like any other LaTeX package. There is a link at http://wiki.lyx.org/Examples/Calculyx to a zipped archive currently in a Dropbox folder, and a screenshot (.png format) of a one-page LaTeX document and the resulting pdf with a few example calculations at https://www.dropbox.com/s/7djkyjs44bpraol/Screenshot%202014-11-24%2013.52.07.png?dl=0. The LaTeX may look complicated, but using LyX, all that is as ever hidden. One simply enters expressions in the LyX math editor as usual. Calculyx requires the three LaTeX3 bundles l3kernel, l3packages and l3experimental. Because a main routine uses a command that was introduced to l3kernel on 18 July 2014, the version of l3kernel must be later than this. The calculational engine for calculyx is the floating point module l3fp in l3kernel. I have tried to ensure as much as possible that calculyx reads expressions as mathematicians write them. For instance it will digest \sin 3x - 3\sin x + 4\sin^{3} x (for a specified value of x, say \pi/6) without parentheses around the arguments and with the superscript in the wrong but familiar place. It will digest the common arithmetic operators, plus variants like \times and \div, the familiar trigonometric and hyperbolic functions and their inverses, the exponential and natural logarithm, fractions (\frac, \tfrac), square root and \surd, factorials ( using !), binomial coefficients (\binom, \tbinom), \gcd, sums and products (\sum, \prod) including infinite sums and products, limits (\lim), derivatives (1st and 2nd order), including Cartesian 2-d and 3-d Laplacians, and definite integrals in one variable. Results are generally presented in the form: expression = result. There is also a (multi-column) table creating command and another which will iterate a function (for the chaos theorists). The package contains a novelty that I think could be exploited more widely. Some calculations are computationally intensive. So as not to burden the compilation of the pdf with them, these calculations can be parked either in a LyX note or in an inactive branch. Instant preview works in both places (with a caveat for LyX notes). The result of the calculation can be saved to a LaTeX control sequence. Calculyx automatically saves such control sequences to a file. They are then available for inserting elsewhere in the document -- even at the start, long before the place where the calculation is performed. If you are prepared to set up a converter and copier, then the file containing the control sequences can be saved in the document directory -- or copied to other directories whereby the results of those parked calculations are made available to these other documents. By this means selected items in LyX notes or inactive branches can play a part in compilation to pdf. Andrew

I don't have time right now to play with new toys but I look forward to testing it someday. Scott

The 2.1.2.1 build is not better than 2.1.2 on Mavericks. You may use the Carbon package of 2.1.2 to get the correct on screen rendering. Stephan
