[sage-devel] Re: Issue with quick start

[Matthew Schroeder]

Dear John,

Thank you for your interest in resolving this problem.  

To answer your question I am referring to  
http://www.sagemath.org/tour-quickstart.html.  I was reading this to get an 
idea of what SAGE can do, when I hit this road block :)

"Sort of supports" my point?  I tracked down a video of an interview with a 
professor of Linguistics, within which she addresses this very issue.  
During these dark times in America (and the world) 
in which the expert is increasingly marginalized, I am surprised to see Dr. 
Murphy's comments so readily dismissed here in an academic forum.Please 
visit her home page  at the 
University
of Sussex.  On her homepage you will see that Dr Murphy's areas of 
expertise include "American English" and "British English".  In watching 
the video, I was struck by the rich and long history of this problem. 
I was hoping that by presenting this information, others would have the 
intellectual honesty to move past their individual preferences and just 
consider the facts.  Doing this seems the only way that mistakes  like 
"Maths"
will ever be corrected.

I assume you're joking. With this assumption: whoa! You found something on 
the internet, in fact a YouTube video, which sort of supports your point. 
You must be right!
 
Anyway, what "quick start" are you talking about? The phrase "symbolic 
maths" does not appear anywhere in the Sage source code, nor does 
"numerical maths".

Chris, who wrote  https://github.com/abelfunctions/abelfunctions, which is
a big package for Sage, is one of the people who works at Amazon on
SageMaker, so maybe there is hope.

Short answer: no. To run a package test suite you need to have the source 
unpacked
and built. So if you want to do that, you have to keep all the build 
directories.

Note that in most case you don’t need a rebuild to run the test suite. Just 
going in
the build directory and running “make check” is enough in most case and it won’t
rebuild the whole thing. But you have to keep the build directory (and the 
source
if it is an "out of source” build).

Thank you, François. That's what I was afraid of...

Do you think it could be worthwhile to create the possibility of running a 
package's test suite without re-building it ? Possibly immediately after 
creating the possibility of *removing* an installed package ?

Re: [sage-devel] Is there a way to run a package's test suite WITHOUT reinstalling it ?

[François Bissey]

You have to install the package with the “-s” option:
  -i [opts] [packages]-- install the given Sage packages.  Options:
   -c -- run the packages' test suites
   -d -- only download, do not install packages
   -f -- force build: install the packages even
 if they are already installed
   -s -- do not delete the temporary build directories
 after a successful build
   -y -- reply yes to prompts about experimental
 and old-style packages; warning: there
 is no guarantee that these packages will
 build correctly; use at your own risk
   -n -- reply no to prompts about experimental
 and old-style packages

The only way to be able to run the test suite again and again is to keep the
build directory and run the test suite manually from there.

./sage is meant to be started in the same directory in which ./configure 
and make were run.
While this is not a standard behaviour, you might have noticed that Sage 
does not (yet) support "make install".
