MaplePrimes - answers and comments on Question, How to access the code of a loaded customised package.

kernelopts(opaquemodules= false)

After using the command kernelopts(opaquemodules= false), you can use the command showstat to list the code of any procedure in a module (or package), both exported and local procedures.

:: (double-colon)

As of Maple 14, non-exported module locals can be accessed by the showstat command using the :: (double colon) as opposed to :- (colon minus).

Using the double colon, module locals can be viewed regardless of whether kernelopts(opaquemodules) has been set to false.

See Joe Riel's comment, though, on nonassociativity and the potential need for bracketing.

Thanks

@pagan Thanks, pagan, for helping me get up to speed on the newer Maple syntax. I'm a few years behind!

Further help needed: further information.

Let me thank you both for your time and for your answer!
I have added the line of code that seemed the most straightforward to me. The name of the package I am loading is MarriagePack and the procedure I'm investigating is stableMatching. It is part of a file I have loaded called mccgp. Here is a screenshot.
For your information I am studying the Gale-Shapley Algorithm. This is where I am at so far, it seems that information about this package is a little bit more complicated to access that I had imagined. Or maybe my only-basic knowledge of Maple does not allow me understand the output I am getting on this.

The first couple of lines are not very clear to me but I was instructed to just copy them in order to implement the package. I think you can disregard them as I have tested the stableMatching function and it seem to be doing the job it should (or the way I loaded this package is the reason for why I only got such limited code of the procedures in play)

Thank you again.

P.K

PS: Please excuse my amateurish screenshot.

showstat(MarriagePack::sM);

@pkassar Ok, so it looks as if `sM` is a local member of the module `MarriagePack`. Hence you might examine its contents with either,

  showstat(MarriagePack::sM);

or,

  interface(verboseproc=3):
  kernelopts(opaquemodules=false):

  eval(MarriagePack:-sM);

Success

@acer I managed to piece it together and get all the code for the procedure! Thank you very much for your help and everyone who answered this post in a record time!! This last piece of information was the breakthrough!

  interface(verboseproc=3):
  kernelopts(opaquemodules=false):

  eval(MarriagePack:-sM);

There's quite a bit to decypher now I better get to it. Thanks again everyone.
