ctrl I is useless - worlds worst editor,interface about wxmaxima HOT 14 OPEN

Nr. 5 isn't caused by wxMaxima but by Maxima which lies at https://maxima.sourceforge.net. The underlying problem is that a truly intelligent assume database would be affected by the halting problem (which means: If you allow it to make too complex decisions it might use indefinite amounts of time. ...but the current assumption database isn't the strongest point of maxima, admittedly.

The Rest I cannot reporduce. Are you using wxMaxima on Windows? If that is true: Would you be willing to try the installer you can find at https://wolfgang.dautermann.at/maxima/nightlybuild/? I guess they have been resolved already. ...or I don't understand the problem.

Thanks in advance,

Gunter.

yes using wxMaxima on windows 7. What do u mean about the installer ? What will that do to what I have already? I may but what does it do ? What problems or issues may it cause? Does it install a new version of maxima? Is there a way i can for " undo " it if desired ?

Yesterday I have accidentally broken the Nightly Build. Which means I hope tomorrow's version will work again.

If it works again the installer comes with a maxima that also contains all bugfixes that have been written since the last release. I hope if the current problem is solved the new installer will only bring improvements, not problems. If that isn't true feel free to open a ticket at https://github.com/wxMaxima-developers/wxmaxima/issues (If possible please file a separate ticket for every bug which makes resolving one bug at a time easier).

...and you can always uninstall every version of maxima and wxMaxima or install two versions on the same system or (if you want) even tell wxMaxima's configuration dialogue you want to use the maxima from a completely different install. In open-source projects all of these possibilities tend to work just fine and maxima normally is proud that it is up- and downwards-compatible.

Forgot to tell: The current nightly build works again - and contains over a hundred bug fixes.

Nearly everyone gets this message, but the bug tracker still works fine. No idea what causes it but if you want you can ask the maxima-discuss mailing list if they have an idea.

Even a fresh start with wxMaxima 18.02.0 on ubuntu 18.04 will not give a correct result for

trigsimp(1 + tan(x)^2)

It just parrots back trigsimp(1+tan(x)^2) instead of 1/cos(x)^2, which is the correct answer.

Yet xmaxima gives a correct result every time for trigsimp(1 + tan(x)^2): Result is always 1/cos(x)^2

This version of wxMaxima on ubuntu seems to be very sensitive to spaces and starts to break when entry mistakes are made. I have to clear memory and restart maxima, especially if wxMaxima has been running for a long time.

Lately I've been starting both xmaxima and wxMaxima for older tutorials like Woollett's Maxima By Example. When wxMaxima goes off the rails I try it in xmaxima. Sometimes it's an entry mistake on my part, but often wxMaxima requires a complete restart to get the same results as xmaxima.

Will try to build or get a newer version and report back with the results
Maybe it's just out of date, b

Update on trigsimp(1+tan(x)^2 problem:
If I type in 1+tan(x)^2; first, hit enter (changed to enter alone for execution)
then type trigsimp(%)
then I get the correct result 1/cos(x)^2
Shouldn't trigsmp(1+tan(x)^2) on one line work just as well?
I like the wxmaxima interface better, but the console has some strange glitches.

from wxmaxima.

What???
After forcing the result with the 2 line solution, now the one line solution is working.
Something seems slightly broken here - again. will try a new version next.

Shift+Space inserts a non-breaking space. Two years ago for a short time there was a big that caused maxima to interpret non-breaking spaces as character, not as space. In current wxMaxima versions this problem should be resolved.

Thanks Gunter!

That time frame is about right for this version to have that bug. I have to build ncurses6 and some other libs from source to use the 5.42.1 deb packages. If that fails, will build from latest git or tarball.

from wxmaxima.

The latest git version should have many additional help menu and right-click menu items that I hope are helpful => I would recommend that version, currently. Will make a new release once we worked around all the breaking bugs in MacOs.

That somehow feels like you were running out of RAM. The question now is: Did you run out of RAM, because the problem you were trying to solve was bigger than your RAM - or did you encounter a bug in wxMaxima or a bug in maxima - or in the lisp maxima was compiled by. All of these are possible.
