The example presented above by Ber7 shows clearly one of the main problems of the current version of the SMath Viewer: a user is forced to use two-column interface and forced to use several tabs to make viewer's version of the SMath document compact enough. Currently a user has to input data in the first tab and to switch application to another tab to see results of calculations and/or plots. Most of engineers and nearly all students prefer "what if" style of applications, when input data and results are put together on the same screen (fortunately, today's computers have sufficiently big and wide screens). In such a case it is easier to check and compare results for several possible input data sets.

I must confess, that tabs are very useful in such stand-alone applications. Additional tabs can be used for a Help page, notes, etc. I think, however, it would be nice to be able to have a "wide-screen" viewer with 4- or 6-column interface in the future. Just put today's two-columns pages in one tab, side-by-side.

In any case, IMHO Viewer is extremely useful and important update of the SMath Studio.

It's not true ... the calculation it's made in real-time over each tab, you just need to update the input field value with the tab key (update and move to the next input field) or the enter key (simply update the field) (see the screenshot)

Thank you. I'm agree with IVR, pressing of ENTER after input changed maybe not obvious for some users. I will add a possibility to see current input state (to understand is field updated or not) and to initiate recalculation by mouse. I have some ideas...

Columns. Yes, IVR also right here. I understand the issue and in future versions user will be able to set worksheet columns or even change controls properties (size, location, etc) using some simple designer built-in into SMath Studio. But anyway, I'll do my best to provide the easiest way to generate output applications. Current implementation introduced mostly to show to community another vector of my development. And I hope you enjoy it.

Andrey, for testing of viewer application it would be very helpful, to have some shortcut for export. This could be a button in the tool bar or a hot key. It could export the sheet to the recently selected format and name (the latter reset upon each change of the sheet name. Ctr-S still would save the sheet as .sm file.

If I understood you well, then yes, I will add an option to make it possible to export worksheet with all current changes as an *.sm file. It will be only an option in the File > Properties dialog (2-nd tab) with "false" by default. This is because one of the main ideas of SMath Viewer - ability to protect your source worksheet.

currently, the file property settings for author and company are not reflected in the generated exe file. The file manager displays the metadata of the plugin, not of the exported sheet. I guess that changes are limited to the commercial version (which is perfectly ok)

Hmm. Author should be specified in file properties. Try to hover output exe with a mouse:

I also guess, that the other metadata will some day go to an "About" button of the exported app, won't they?

Exactly!

Wrote

It would be nice if the exported app would include only the required plugins. Currently, everything is exported, even those which are disabled in the plugins manager. Advanced users typically have their installation full of stuff, which then blows up even the simplest example apps. An alternative is, of course, to have different installations with different selections of installed plugins. That, however, is hard to maintain consistently. I see, of course, the problem of how to determine the dependencies in multifile plugins just like the maplewrapper or dataexchange. If there is an easy solution, that would be welcome.

You're right. I didn't know any common way to determine the dependencies between DLLs in plugin's directory (especially for unmanaged DLLs). But I think I've found a solution already, so in the next versions this will not be a problem anymore.

EDIT: The print preview looks like it would show the title or filename but fails to do so.

Correct. Will fix it.

Wrote

EDIT: For commercial users might be important to check the print preview, because it contains more information than the app GUI (e.g. covering of variable names and implemented formulas by description strings is lost)

Yeah, will think about it. Thank you.

Wrote

EDIT: Does the statement "SMath viewer is free for learning" include teaching in acedemic context?

Yes, absolutely.

Wrote

EDIT: How can I change the language setting of the viewer application (e.g. in order to test translated versions)?

For now you need to change OS localization setting to test translations. Plan to add additional toolbar button with all available languages listed.

Thank you, mkraska!

Best regards, Andrey Ivashov.

While reading IVR's post I've recalled this one on Bret Victor's ideas about interactive interface design.

You may find some inspiration by watching some of his videos in youtube like this one

Maybe you have imagined something like panels of preview small graphs all changing at the same time as the user moves a slider control..to name some of the user interfaces used in Bret's Tangle.

Andrey, thanks for the detailed response. As for the above issue, I failed to make myself understood. My intention was not to facilitate extracting the source sheet off an application but rather to facilitate the export process from within SMath Studio. Now I have to call the Save as dialog and then choose the excutable format from a long list (if there are many plugins installed). This requires two precision mouse actions, which I hated when I reproduced your formatting steps in the Viewer introduction.

One might even go further and have a button "run", i.e. export and immediate launch of the app from within SMath Studio.

It might be sensible to make the "run" button configurable (export format and action to take afterwards)

As for the metadata: I entered german and english metadata. The german title is "Beispiel" and goes to the window title of the Viewer window (with "- SMath Viewer" appended. The english title goes to the exe file metadata as displaed in the dynamic info pop up (mouse hovering over exe file). Author name and company are set in both languages but have no effect.

Hello,

Here is another simple sample representing checkbox using. It crossed my mind that it would be quite interesting to have the ability to see and change a data matrix from within SMath Viewer.

Yes, that's the idea of immediate connection to what you are designing/changing.
Sorry for my insistence, I just think it would be great to have in SMath Viewer some of the gui controls from this reactive document.

Hi all;

I noticed a "nonlinear behavior" of the Viewer: when an area is collapsed and protected works as a combination of a collapsed area and a separator; moreover the calculations are broken.

Fixed. Author and Company is now shown in application meta-data. Copyright item will contain "Copyright © SMath" for free version and "Copyright © " - for commercial.
Thank you!

Best regards.

I enjoy working with the SMath Viewer for recurring work in mechanical engineering.
As soon as I'm done, I'll translate the worksheet in English.

The central element of this exe is the Tab 3 "Geometry" because it brings the user close the effect of dimensional change graphically.
Are there any input or suggestions for improvement?
I found so far no options for 2D graphs similar to the plug-in of Dr. Martin Kraska to increase the intelligence of the charts (eg. automatic adjustment to scale)

Thannk you all ad best regards

In one of the "Utilities" posted few months ago, there is an algo that takes :
function name, the range [then auto range the plot], and parameters.
That means you can view as many plots as you want with parameters of your choice
and each plot auto-ranged. The viewer is another story.
BTW, thanks a lot Davide for rescueing "Budapest39" ... most appreciated.
I have not tested the length of the data set because of the Sigma summator.

Jean

I have added DCT2-II & Idct2-II ... limited to 32 [because of Sigma.
Will post in few minutes

... [suite], that's what I meant:
1. algo style construct, includes individual range,
2. includes user parameters [no limit]
3. each "plot set" is an export
4. you can "nest" the "All" for different style export.

IMHO, I think the "viewer" can be constructed similarly.

Hi Andrey,

The include plugin works fine with free version of SMath Viewer, however if I generate the .exe file using a valid key for paid version, I get error.

Basically, for free version:

Цитата

include("_steel.sm" )=15

for paid version:

Цитата

include("_steel.sm" )=0

(Thank you for your work on SMath!)

*************************************

[1.] You can't be more right: two many dormant plugins that are red for most of them.
It may be one of those buggers that freak Smath compute complex .... limits Sigma summator in dct2 [from last night].
My Smath survives for what it does by itself and luckyly Maple survives too !!!
In the context "Viewer", I don't even understand what it should do.
EXAMPLE: That Matrix plugin Excel style => piece of crap, my Matrix treasury does many times more.
Why ? because it takes Smath results and treats Smath results ++++

[2.] My "Smath preview" shows: Year/Month/Day Hour/Minutes/Second ... page 1/2, page 1/3 ...

Cheers to all collabs.
