Hello,

I'm looking for version 5.2 and the above link is broken in master 
www.sagemath.org pages.

Some emails, in this forum, are also pointing to that link.

Where can I find SageMtath 5.2 to try to compile it on Ubuntu 16.04?

Thank you.

Re: [sage-devel] Re: how we develop sage

[Pedro Cruz]

(1) Sage developers could be better informed of what are they are going to 
affect if sage, as an "author tool",  send usage statistics about each 
"sage-lib" related function:

- Author should put sage in "send usage statistics mode"
- The same author would be warned if any of those functions starts to be 
deprecated.
- And maybe, if authors freely send files to be kept and seen as "testing 
examples" like in "sage -t .sage"


But after a new deprecation warning, I'm thinking of implement one of this 
solutions to my code:

(2) A tool to automatically change the deprecated "simplify_exp" for 
"canonicalize_radical" inside sage files;

(3) Create my own local "simplify_exp" that mimics original "simplify_exp" 
because here authors enjoy applying "simplify_exp" to exponential 
expressions.

[sage-devel] catch a "sagemath" DeprecationWarning

[João Pedro Cruz]

Hello,

I was expecting the following to catch the DeprecationWarning

import warnings

warnings.filterwarnings('error',category=DeprecationWarning)
try:
print (exp(x)*exp(3*x)).simplify_exp()   #example with exp function
except DeprecationWarning:
print 'MegBook.py say: exercise needs review!'

but it does not. I still got

DeprecationWarning: simplify_exp is deprecated. Please use 
canonicalize_radical instead.
See http://trac.sagemath.org/11912 for details.
  print (exp(x)*exp(_sage_const_3 *x)).simplify_exp()   #example with exp 
function


*How can we catch this "type" of* DeprecationWarning  ?

I've checked 
   https://github.com/sagemath/sage/blob/master/src/sage/misc/superseded.py
but reached no conclusion.

I appreciate help,
Thank you.

Pedro


The following works easy:
try:
raise DeprecationWarning
except DeprecationWarning :
print 'Got it'

[sage-devel] output results depending on platform

Hello,

I would like to output results with the following code:

and this code is inside a module and "MEGUA_PLATFORM" got value in a

How to import "salvus"  identifier to use salvus.file() into some module ?

Re: [sage-devel] Sage code for educational purposes only?

[Pedro Cruz]

+1 for the  package educational-algorithms but called 
educational-packages or educational-library.

MathSciNet catalog has the category Mathematics education

http://www.ams.org/mathscinet/msc/msc2010.html?t=97-XX

being the last topic after all the mathematical edge cutting works.

This could inspire an educational-library (this name is maybe more 
general than just algorithms).

 I think this was the first-ever public release of Sage.   I made it 
 inspired by a conversation at the 2005 JMM with David Joyner, who saw 
 me working on my private code there. 

 Based on that date, we could say that Sage will be 10 years old this 
 Friday.Alternatively, it seems the first tarball I posted has the

[sage-devel] How to make a gallery of pairs code and sample ?

Good morning,

in the context of Sage and Sphinx documentation system (or other doc 
system)  is there any direct way to do something like the TikZ community is 
doing ( http://www.texample.net/tikz/examples/ ) ?

We are looking for a ready to use framework. 
The problem with Sphinx is that it puts thinks vertically like in 
http://www.sagemath.org/doc/a_tour_of_sage/ .

Thank you.

is defined to see if notebook is being used.

Thank you,
Pedro

[sage-devel] Re: Touch Interacts on iOS

[Pedro Cruz]

Can people test this functionality before we try to add it to the sage 
notebook? 
 If you have an iOS or
Android device, create an interact at aleph.sagemath.org and try 
manipulating the controls.  

On iPod Touch, the n^2 example,

@interact
def f(n=(1..10)):
print n^2

works well.

[sage-devel] sage, sphinx, and external package

[Pedro Cruz]

We  would like to use Sphinx :automodule: in our sage external package that 
depends on sage library (from sage.all import *)
Because of this dependency, my local sphinx-build tries to import sage.all 
 and this error occurs:

/home/jpedro/all/meg/meg-0.2/doc/source/meg/ur.rst:6: (WARNING/2) autodoc 
can't import/find module 'meg.ur', it reported error: No module named 
sage.all, please check your spelling and sys.path

I've added all paths I know to Sphinx conf.py:
  sys.path.append('/home/jpedro/sage/devel/sage/')
  os.environ['SAGE_ROOT'] = '/home/jpedro/sage/devel/sage/'
  os.environ['LD_LIBRARY_PATH'] = '/home/jpedro/sage/devel/sage/local/lib'
but it will always produces a different error.

For Sage modules there are instructions here:
   
http://www.sagemath.org/doc/developer/sage_manuals.html#building-the-manuals

Is there a way to use Sage own sphinx-build to avoid all those path 
problems ?

[sage-devel] Re: sage, sphinx, and external package

Well, it seems this solution works but maybe there is something simple:

Inside sphinx Makefile use:

SPHINXBUILD   = /home/jpedro/sage/sage -python 
/home/jpedro/all/meg/meg-0.2/doc/sphinx-build

where file sphinx-build file is a copy

[sage-devel] Re: sage: documentation strings

[Pedro Cruz]

Dear Minh and Keshav ,

thank you for fast answer.

There are now two facts I think new sage programmers like me would like to 
read in the development user guide:

1. An example that   ... is currently in use instead of natural ...: 
(until the fix is done).

2. An example for modules in section Beyond the Sage library:

 If you are building an external optional package please use 
 SAGE_PATH=/my/module in .bashrc.

otherwise sage -t file1.py wont find a file2.py in same folder.

Thank you,

Pedro

Re: [sage-devel] sage: documentation strings

[Pedro Cruz]

I appreciate help on using multiline strings containing % (this is usefull 
for latex strings). In the following I want that % is not converted 
to _ip.magic.

This also affects sage docstrings (using ... for continuation). In pure 
python docstrings this is not a problem.

CASE 1

sage: txt = One
: Two
: %Three
: Four
: 
sage: txt
'One\nTwo\n_ip.magic(Three )\nFour\n'

CASE 2

sage: txt = rOne
: Two
: %Three
: Four
: 
sage: txt
'One\nTwo\n_ip.magic(Three )\nFour\n'

[sage-devel] sage: documentation strings

[Pedro Cruz]

I've search here 

http://www.sagemath.org/doc/developer/conventions.html#documentation-strings

looking for this type of docstring:


   sage: txt=r''' hello
   : this goes on '''



This does not work using sage -t module.py. 

However python works like:

r
1+1
   2
txt = r''' um
   ... ola  dois '''
print txt
 um
ola  dois 
 


How can I test multiline instructions using sage: ?

Thanks. Pedro

Dear Leif,

thank you for the amazing and trivial suggestion

 Adding your directory where m1.py and m2.py live to SAGE_PATH and
 running (e.g.)

This link is related:

http://ask.sagemath.org/question/415/how-do-i-get-sage-to-honor-my-pythonpath

So this info could be in Sage Developers manual.

Re: [sage-devel] documenting a new package out of Sage Math tree.

[Pedro Cruz]

Dear William and Sage developers,

I request help once more about testing sage -t  a package that was not 
installed on Sage using sage -i.

The package name we are developing is named meg and is almost ready. 
Testing (sage -t) is this last step.
All of the package code is on /home/jpedro/all/meg/meg-0.2/  (a set of 16 
*.py small modules)

To use it while writing/changing code I've created a symbolic link to
   /home/jpedro/all/meg/meg-0.2/
from 
  /home/sage/local/lib/python2.6/site-packages/meg
and using
sage: from meg.all import *
all package functionality is working well.

EXCEPT that
 sage -t some_module.py 
is producing details at message bottom.

Must I do the following cycle ?
1. pack (tar)
2. install
3. issue sage -t some_module.py
4. change some_module.py
5. go to 1.

What am I missing here 
http://www.sagemath.org/doc/developer/producing_spkgs.html ?

Thank you.

Pedro

Re: [sage-devel] documenting a new package out of Sage Math tree.

[Pedro Cruz]

The -force_build did not work and I believe it's a problem of how to use 
import on new Sage packages.

Recalling first message, I want to build a new optional package based on 
*.py modules.
It seems that 
   sage -t my_module.py
moves my_module.py to a .sage/tmp folder and there executes the sage: 
examples.

But if   my_module.py  contains import my_other_module a problem came up 
because my_other_module.py is not going to be moved to the .sage/tmp 
directory.

What design principle am I missing?

Thank you,
Pedro

[sage-devel] documenting a new package out of Sage Math tree.

[Pedro Cruz]

I am creating a new package in python separated from Sage tree (following 
[1]) but depends entirely on Sage Math library (and also on Sage Notebook), 
However
   sage -t somemodule.py
is not working because of imports. == But using this package normally 
causes no problems with imports!  

I'm following [2] for documenting python sources.

[1] http://www.sagemath.org/doc/developer/producing_spkgs.html
[2] http://www.sagemath.org/doc/developer/coding_in_python.html

Maybe sage -t somemodule.py is only when coding directly on sage tree. Is 
this the problem? 
Should I put the new package directly on Sage tree using [3] ?
[3] http://www.sagemath.org/doc/developer/walk_through.html

Any advice?
Thank you, 
Pedro 
 
During production I have created a link inside
   ~/sage/local/lib/python2.6/site-packages
to 
   ~/my_package
to avoid reinstalling the package everytime.

To test the package we wrote commands in Rest strings like:

EXAMPLE:

   sage: from new_package import MyClass
   sage: a = MyClass(10) + MyClass(12)
   MyClass(22)

[sage-devel] Re: MATLAB: viable alternative...?

[Pedro Cruz]

Dear Sage project leader,

My experience is about Sage 4.6.2:
For numerical computations I have quieted of Sage/Sagenotebook and use only 
scipy/numpy directly using vim and shell. 

Sagenotebook has the advantage of shareable over the net worksheets but the 
editing 83 functions on it became hardwork because of those jumps on screen 
and no colors. I had problems making/seeing graphics. (maybe that is not a 
problem now)
Sage has the advantage of symbolic calculus which could help confirming some 
numerical calculations but the integration with scipy/numpy needs some 
attention to know if a given parameter is in Sage world or scipy/numpy 
world. Also Sage has the problem of taking to much time to load and using 
attach reveals some problems.

This is what I remember that lead me to the decision of quiting 
sage/sagenotebook for the specific purpose of pure numerical computation. 
(matlab was never needed).

I will improve this notes as soon as a new numerical projects began. Is 
there any thematic group or wiki for numerical sage ?

[sage-devel] Re: search_methods() to search the methods of an object

[Pedro Cruz]

Maybe there's an advantage in change from

   X.kertab  (look through ker* methods...)

to

   X.kertab  (look through methods that contain ker in name ...)

In fact, it's what

   X.tab  (look through * methods...)

do.

 Here's something that happens to me: I have an object X that has a *lot* of

 that are annoying.

 How about a function, somewhat like search_doc, search_def, and friends,
 that accepts an object and a string, and returns methods that match that
 string? Would you find that useful?

 Here's what I just wrote. Try dropping this into sage/misc/sagedoc.py,
 and adding search_methods to all.py in that directory:

 def search_methods(x, s):
     r
     Given an object x and a string s, this returns a list of methods of
     x that contain s. A better version of this would have an option to
     include or exclude methods that begin with an underscore, do proper
     regexps, etc.
     
     return [m for m in dir(x) if s in m]

 Then you get:

 sage: m = matrix(2, [1,2,3,4])
 sage: search_methods(m, 'kernel')
 ['_decomposition_using_kernels', '_kernel_matrix_using_padic_algorithm', 
 '_kernel_matrix_using_pari', '_rational_kernel_iml', '_right_kernel_matrix', 
 '_right_kernel_trivial', 'integer_kernel', 'kernel', 'kernel_matrix', 
 'kernel_on', 'left_kernel', 'right_kernel']
 sage: g = graphs.PetersenGraph()
 sage: search_methods(g, 'loop')
 ['allow_loops', 'allows_loops', 'has_loops', 'loop_edges', 'loop_vertices', 
 'loops', 'number_of_loops', 'remove_loops']

 Thoughts? Should I open a ticket for this?
