Description (last modified by vdelecroix)
Sometimes import_statements fails in given a working answer (pi, CIF, ...). See the complete list in failed_import_statements.
We fix the bug and the solution proposed contains a new function *which_import_statements_fail* that build the list of name in sage.all for which the answer of import_statements fail to import it. It also fixes many input: only one import statement fails "maxima_calculus" and with 62 occurences we obtain a "from sage.all import XXX" (see the precise list in answer_sage_all).

comment:10 Changed 2 years ago by vdelecroix
I fixed (checking one by one) all the exceptions in the linked file (except the is_* stuff)... and this is now ready for review !!
It is much more robust but it would be marvellous to detect deprecated stuff (there is a note about that in the documentation of the function).

Helloooooooooooooooooooooooo !!!
Some remarks:
1) Affected ? That's only correct in french I thing. Do you want to translate "variable assignment" ? But I believe that in this context messages like "x is defined by <...>" or "x is equal to <...>" would be clearer.
2) And one can actually check that FareySymbol and sum are aliases. Would be better with :func:`FareySymbol` for the html doc.
3) If there is an option to display the import line for lazy functions then the output of this function is meant to be copy/pasted. Thus, shouldn't the Warning line begin with a # ? Otherwise it is impossible to copy/paste it into Python code.
4) use it has a name : as a name.
5) This function is awful. It may be nice to split it into identify_module, identify_object_from_module, identify_by_search_through_modules, identify_object_from_source_code, etc ?... Would make the code a bit clearer :-P
6) names_pattern = dict((i,j) for i,j in whatever) can be rewritten as {i:j for i,v in whatever}. Would make your names_pattern line clearer.
7) at the beginig
8) Why this print_or_update function ?
I have not understood everything of the code yet, but fixing the things above might help ^^;

Hi,
Thanks so much for telling me to rewrite it ! Now it is simpler and cleaner and I hope you will understand everything.
I do have two things to solve before getting this in a needs-review status
- try to not load extra modules in the function find_objects_from_name (see the thread on sage-devel)
- possibly move the functions find_objects_from_name and find_object_modules in sage.misc.sageinspect
See you soooooooooooon

Hello...
Really I tried, and I don't get a word of what the main function does. I don't get it, I don't get how it does anything, I don't even get at every moment which variables can be assumed to be defined, what is left to be found, I don't get the flow of it. Sorry, I tried and I just don't get it.
If you cannot split it into subfunctions further, please add comments to say from time to time "This has been defined, now we look for this". I just don't get it, all I can do right now is check that three consecutive lines make sense, and that's not doing a very good review job.
I add a small commit with a couple of unimportant modifications.
Some remarks:
- Why is exclude_pattern overwritten when module is None ?
- "Here we test some instances::" is followed by nothing
- Why should calling import_statement on a module raise an exception ? What if I do not know where graph_decompositions is located ?
sage: import_statements("graph_decompositions") ... ValueError: the object '<module 'sage.graphs.graph_decompositions' from '/home/ncohen/.Sage/local/lib/python2.7/site-packages/sage/graphs/graph_decompositions/__init__.pyc'>' is a module
More importantly, what should the following code do : raise an exception of continue ?
raise ValueError("the object '%s' is a module"%obj) continue

Hello,

[...]
Ok. I had many comments into the code, especially about what the variables are.
- Why is exclude_pattern overwritten when module is None ?
Because you can crash Sage (really):
sage: from sage.misc.dev_tools import load_submodules sage: load_submodules(sage.libs) load sage.libs.coxeter3.coxeter_group...failed load sage.libs.cremona.homspace... suceeded ... load sage.libs.singular.groebner_strategy... suceeded sage: quit # BOOOOOM
- "Here we test some instances::" is followed by nothing
I removed it.
- Why should calling import_statement on a module raise an exception ? What if I do not know where graph_decompositions is located ?
sage: import_statements("graph_decompositions") ... ValueError: the object '<module 'sage.graphs.graph_decompositions' from '/home/ncohen/.Sage/local/lib/python2.7/site-packages/sage/graphs/graph_decompositions/__init__.pyc'>' is a module
Fixed.
