2011-09-06 Thread robin hankin

Hello Justin

thanks for this...I'm more familiar with the R help list, where
there's a very heavy emphasis on not wasting bandwidth,
and replies not much less terse than 'rtfm' are very common.

So, I'm finding the more tolerant atmosphere in sage to take some
getting used to!

best wishes

Robin

If you use linux, you aren't that far from (command-line) Mac OS X.  It's 
basically a BSD unix at that level.

As I said, you had to replace "$SAGE_ROOT" with a real path.  But you've gotten 
past this.

'quit' is a command, not a procedure call; in both Python and iPython, you call 
"quit()", but apparently, in Sage, not so much :-}.  Note that Sage is 
essentially Python, with a modified iPython front end, and a bit of syntactic 
sugaring with a preparser.  We throw a few things like this in just to keep the 
hapless user on his toes.  Or hers.

No need.  The precompiled version should work just fine.  You only have to 
survive the learning curve :-}

Keep asking questions and reading documentation.  

Apropos of documentation, there is a lot available

but what's there can always use improvement.  Feel free to browse and either 
ask questions or submit bug reports (cf. 
).  Also, there is some built-in 
documentation in Sage.  To get an idea, type (at the prompt) the beginning of a 
procedure name (e.g., there is one that creates a number field):

  sage: Number[TAB]

should produce a list of four known Sage identifiers.  Typing

  sage: NumberField?

will get you the sourcecode documentation for this procedure.  Using "??" 
instead of "?" will get you the documentation plus source code, so you can see 
the implementation details.

That may help get you started.

We're here to help.  Sometimes, we succeed.

Hello Justin

thanks for this.

(I'm a linux user but currently getting to know macosx).

$SAGE_ROOT was null, but I can run it from the commandline by changing
to Applications/Sage-4.7.1-OSX-64bit-10.6.app/Contents/Resources/sage/
and running ./sage.

And the integral() command seems to work but I have other problems:

You open a Terminal window, first, and make sure that window has focus.

Next, switch to the directory containing the precompiled version (referred to 
by the cognoscenti as $SAGE_ROOT):

 $ cd $SAGE_ROOT

(replacing "$SAGE_ROOT" with "/path/to/directory/containing/sage") (without the 
"'s :-})

Then, type
 $ ./sage

Hi.

thanks for this.

@justin:  how do I run sage from the command line?  I  use the
precompiled version and am unsure how commandline sage works.

@kcrisman:  'maxima_console()' appears to hang, giving message:

x.simplify() seems to hang too.

What happens if you do

sage: maxima_console()

and what happens with

sage: x.simplify()

(which just sends it to Maxima and back)?

[sage-support] Re: integral() error

2011-09-01 Thread Maarten Derickx

I have OS X 10.6.8 also but I don't have the same version of sage installed 
currently as you (I have sage 4.7.2.alpha2 and 4.6.1) and I don't seem to be 
able to replicate your error in both the older and the newer install. I 
don't have firefox so could you please try it from the command line (i.e. a 
sage terminal session) to rule out the unlikely case the the macsyma error 
is caused by firefox?

I guess since everything works ok for me, installing a newer version of sage 
should make your problem go away.
