Yes, this should work in principle. I don’t have these tools - the point is:
you have to wrap the command line utility you can use in terminal.
But care for Kornels advice below.

e.g.:
#!/bin/
sh

/Applications/Mathematica.app/Contents/MacOS/MathKernel "$@„

The first line „#!/bin/sh“ is another ritual were you shouldn’t be
creative :) Don’t break it into multiple lines.

The exec in front of the command line utility is again for efficiency.
The shell process created by LyX to start the CAS utility will be
replaced by the CAS utility instead of creating another child process.


for mathematica and
#!/bin/
sh

/Applications/Maple 18/Maple 18.app/Contents/MacOS/Maple 18 "$@"

Again, a million thanks!

You’re welcome.

Yes, Kornel, you’re right. The spaces in path name need quotes.
In case of maxima it was not required to quote the path name because
it doesn’t contain spaces.

Stephan


Stepha, Kornel, Murat, thank you all, it does work, at least for Mathematica, 
still playing around with Maple, for which I haven’t figured out where the 
kernel is yet (and Murat, I do not have that directory on my system.

For future reference, what I did was repeat exactly the same steps to create a 
file called “math” in $HOME/bin (for some reason it did not work with 
“mathematica” as file name), using the commands below in a terminal window:

cat - > $HOME/bin/mathematica < in the terminal window, the other 
two by $ - this is for the technically challenged like me out there.

Again, thank you all!

Maple works in my case, by adding

/Library/Frameworks/Maple.framework/Versions/17/bin

in the Path field of Lyx
The support is very elementary, but I can do 1+1=2 :-) using the evalf
function in the menu for Maple in Lyx

hi Stephan, thanks for the scissor tip, will never look at 8< the same way 
again :-)
I’ve followed all your steps, but sadly still nothing has changed - tough maybe 
I have erred somewhere? Here is what I did:
First of all I created the wrapper file, and put it in HOME\bin, which I had 
already created following your instructions.
Then I’ve run
$ cat $HOME/bin/maxima
in the terminal window, and got the two lines of the new “wrapper” file.
Then put both ~/bin and HOME/bin in the LyX path for good measure, reconfigured 
LyX, closed Lyx and relaunched it, and again, it does not work.
So I thought maybe I should also have run the last two of the three other lines 
of code to be run in the terminal. Did that, but as you can see from the 
attachment after running that command I do not get a “$” sign, but a “>” as 
terminal prompt. Maybe this is the problem?
Thanks for your patience!

No problem. Simply type the 2 lines, cat is awaiting input.
To end the input you have to enter EOF, probably it is control+D.

Kornel

thanks Kornel (and Stephan), but now the result is that the maxima wrapper has 
been overwritten by empty lines!
So just to recap what I’ve done:
1. created the wrapper file, called it maxima, put it in HOME/bin, and checked 
it is there with the correct content by running the command “$ cat 
$HOME/bin/maxima” (no quotes) in the terminal window; I can also see the file 
in finder
2. run the three commands in the terminal window, where after the second line I 
had to use ctrl D to signal end of file
as a result, the “maxima” file has become an empty file (indeed, running “$ cat 
$HOME/bin/maxima” in the terminal window returns empty lines.
No change in behaviour in Lyx. If it helps, I have also Maple and Mathematica 
installed on my machine, but no luck invoking them from LyX either.
screenshot of terminal window is attached in case it is of any help.
Above all, thanks for taking the time with this.

Hi Paola,

I tried to be as verbose as I can - but it was too terse, sorry.

Two points:
1. The dollar sign in front of my command line text shouldn’t be typed.
It’s usual to mark text input as terminal input.
2. The EOF marker is an arbitrary text and should have been typed as given.

I’ll attach a screen shot of a my terminal session to prepared the wrapper 
script.

Finally the correct PATH extension in LyX settings is important.
Either it should be „$HOME/bin“ or „~/bin“ - having both does not harm
but it slightly reduces the startup speed of every external script.

Regards,
Stephan




Dear Stephan,
thanks so much for the time you are taking on this, and apologies for being 
slow! I have tried following exactly what you did, but there seems to be a 
problem when I get to “which maxima” - I get an empty line. On the other hand, 
the
cat $HOME/bin/maxima
does return the contents of the file, and I do see a newly created maxima file 
in the “bin” folder (in finder) - maybe my system is missing some other 
component?
Again, many thanks,
Paola
p.s.
screenshot attached


Dear Paola,

no problem, we’re almost there.

Sorry, I forgot to adjust the PATH setting in terminal.
I have $HOME/bin already in PATH in terminal.
This is not standard, obviously - so let’s add it for the test :)
This is the equivalent of adding $HOME/bin to LyX PATH settings.

See the screenshot.

Regards,
Stephan

Oops, the screenshot… the blue text is my keyboard input.




YAY!!! it works Stephan, thank you ever so much, you have been so very patient, 
never been so happy to discover that 3+2=5 :-)

Presumably I would have to repeat the same procedure to create wrappers for 
mathematica and maple? e.g.:

#!/bin/sh

2. run the three commands in the terminal window, where after the second line I 
had to use ctrl D to signal end of file

as a result, the “maxima” file has become an empty file (indeed, running “$ cat 
$HOME/bin/maxima” in the terminal window returns empty lines.

No change in behaviour in Lyx. If it helps, I have also Maple and Mathematica 
installed on my machine, but no luck invoking them from LyX either.

screenshot of terminal window is attached in case it is of any help.

Above all, thanks for taking the time with this.

No problem. Simply type the 2 lines, cat is awaiting input.
To end the input you have to enter EOF, probably it is control+D.

Hi all,

I’ve searched the list and though this is not the first time the problem
is
noted, I haven’t been able to find any solution. The short of it is: it
just won’t work. So for instance if I type “5+2” then invoke
Edit/Math/CAS,
I only get a lonely = side to the right of the expression, and no result
(see screenshot)>

...

What happens if you call maxima from the console window and input the
string '(5+2);' followed by ? Here I get:
(%i1) (5+2);
(%o1)  7
(%i2)


...

from the console I get the same as you:

 (%i2) 5+2;
 (%o2)  7
 (%i3)

It should work. Do you have the same PATH settings on console?
Note, that I am not on MAC, so only guessing.

Kornel

I know it should work, which is why it is sooo frustrating! I cannot see any 
path settings in the Terminal, but I have put in lyX the same address as the 
one invoked for Maxima run from a terminal window, and still no joy!

The problem is that LyX contains the call of the external utility as hard-coded 
string and it is „maxima“.

The only solution I can see is to wrap the wrapper script „maxima.sh“ located 
inside the Maxima.app bundle
with a utility script like the following code (I cannot attach it - every virus 
checker will block the transport):
=== 8< snip here >8 ===
#!/bin/sh
exec /Applications/Maxima.app/Contents/Resources/maxima.sh "$@"
=== 8< snip here >8 ===

In terminal you may do this:
$ mkdir -p $HOME/bin
$ cat - > $HOME/bin/maxima < means joining the two “8”?
thanks!

1. You need to create the wrapper first and may try it (after creating it) in 
terminal by typing "$HOME/bin/maxima“
2. The wrapper should be placed in folder $HOME/bin (which is created first in 
case it doesn’t exist already by „mkdir“)
3. The snip surrounded two lines is the contents of the wrapper script - „8<" 
and „>8" are the two scissors :)

To explain the terminal commands:
The first terminal command is ensuring the existence of the folder „$HOME/bin“.
The second one (starting with „cat“ and ending with EOF) is one the way to 
create the wrapper script without any editor.
The third command is making your new wrapper script executable.

The 2nd command needs to be entered exactly as you see it.

You can verify what you did by using the terminal command:


It should give you the 2-line-script between the lines surrounded by the 
scissors.

The problem why you has to do it yourself is: I cannot send you any shell 
script.
No virus scanner will let it through. It doesn’t matter if it is useful or not.

Regards,
Stephan


hi Stephan, thanks for the scissor tip, will never look at 8< the same way 
again :-)

I’ve followed all your steps, but sadly still nothing has changed - tough maybe 
I have erred somewhere? Here is what I did:

First of all I created the wrapper file, and put it in HOME\bin, which I had 
already created following your instructions.

Then I’ve run

$ cat $HOME/bin/maxima
in the terminal window, and got the two lines of the new “wrapper” file.

Then put both ~/bin and HOME/bin in the LyX path for good measure, reconfigured 
LyX, closed Lyx and relaunched it, and again, it does not work.

So I thought maybe I should also have run the last two of the three other lines 
of code to be run in the terminal. Did that, but as you can see from the 
attachment after running that command I do not get a “$” sign, but a “>” as 
terminal prompt. Maybe this is the problem?

Thanks for your patience!

I have specified the paths correctly (I think) to where the apps are 
(Mathematica, Maxima, Maple - nothing seems to work), and I can see the 
software calling the app (math-extern maxima), or (math-extern mathematica), 
but no result is churned out.

Here is what I have in the "PATH prefix" field under Lyx->Preferences->Paths:

It seems one has to start maxima.sh to get the command line interface. I’m not 
sure LyX knows it.
In any case one has to add "/Applications/Maxima.app/Contents/Resources“ to the 
PATH.

thanks Stephan, I used “exec

although I also just launch the Maxima.app from the launcher. At any rate I 
have added your line to the path, reconfigured LyX, closed and reopened, but

How did you call maxima in terminal?

I have it installed too and it looks like that:

It seems one has to start maxima.sh to get the command line interface. I’m not 
sure LyX knows it.
In any case one has to add "/Applications/Maxima.app/Contents/Resources“ to the 
PATH.

Hi Kornelm
I think that yolu should point İnci'de the .app package, where the unix binary 
lives.
I do not have my laptop with me, but it could be the Macos folder in the app 
package (your .app file is in fact a bundle containing sub folders, and one of 
them contains the maxima binary

Hi all,

I’ve searched the list and though this is not the first time the problem is 
noted, I haven’t been able to find any solution. The short of it is: it just 
won’t work. So for instance if I type “5+2” then invoke Edit/Math/CAS, I only 
get a lonely = side to the right of the expression, and no result (see 
screenshot)

I am currently running Lyx 2.2.0 on Mac Os Sierra, but I had exactly the same 
problem under Maverick and El Capitan with previous Lyx versions, namely, 
nothing happens.

I have specified the paths correctly (I think) to where the apps are 
(Mathematica, Maxima, Maple - nothing seems to work), and I can see the 
software calling the app (math-extern maxima), or (math-extern mathematica), 
but no result is churned out.

Here is what I have in the "PATH prefix" field under Lyx->Preferences->Paths:

/Library/TeX/texbin:/usr/texbin:/sw/bin:/sw/sbin:/opt/local/teTeX/bin:/opt/local/bin:/Library/TeX/local/bin:/Library/TeX/bin:/Library/TeX/X11R6/bin:/Library/TeX/sbin:/sbin:/usr/local/sbin:/Library/TeX/usr/local/bin:/Applications/Mathematica.app/Contents/MacOS/MathKernel:/Applications/Maxima.app:/Applications/Maple

Can anyone please help?

I'd try calling lyx with '-dbg mathed' parameter from a console window.
Alternatively use View->Messages Pane->Settings
Check 'Selected'
Double click on 'mathed - Math editor'

many thanks Kornel for your prompt reply, I’ve tried what you suggested, and 
what I got is no output, namely:

does this suggest where the problem is?

No, missing: output: '7'

What happens if you call maxima from the console window and input the string 
'(5+2);' followed by ?
Here I get:
(%i1) (5+2);

from the console I get the same as you:

making LyX work with CAS on Mac OS

[Paola Manzini]

Hi all,

I’ve searched the list and though this is not the first time the problem is 
noted, I haven’t been able to find any solution. The short of it is: it just 
won’t work. So for instance if I type “5+2” then invoke Edit/Math/CAS, I only 
get a lonely = side to the right of the expression, and no result (see 
screenshot)

I am currently running Lyx 2.2.0 on Mac Os Sierra, but I had exactly the same 
problem under Maverick and El Capitan with previous Lyx versions, namely, 
nothing happens.

I have specified the paths correctly (I think) to where the apps are 
(Mathematica, Maxima, Maple - nothing seems to work), and I can see the 
software calling the app (math-extern maxima), or (math-extern mathematica), 
but no result is churned out.

Here is what I have in the "PATH prefix" field under Lyx->Preferences->Paths:

/Library/TeX/texbin:/usr/texbin:/sw/bin:/sw/sbin:/opt/local/teTeX/bin:/opt/local/bin:/Library/TeX/local/bin:/Library/TeX/bin:/Library/TeX/X11R6/bin:/Library/TeX/sbin:/sbin:/usr/local/sbin:/Library/TeX/usr/local/bin:/Applications/Mathematica.app/Contents/MacOS/MathKernel:/Applications/Maxima.app:/Applications/Maple

Can anyone please help?
