How to magically define variables and use functional notation instead of methods

Question

I am always too lazy to look up again where it is that one can do these things. Not that I would ever use such dangerous things myself.

Magically define variables (so that you don't have to var('y'))
Magically define functions (so that one doesn't need boof.annoying_method(), but instead can do annoying_method(boof))

Once it's on here, people can find it more easily and put themselves in more danger.

It looks like it is only implemented in the notebook: execute automatic_names(True). (See #7482 for the relevant ticket.)

I knew I could count on you! See http://www.sagemath.org/doc/reference/sagenb/misc/support.html as well for doc. Thanks - in retrospect, should have been obvious, but I was hung up on the word 'magic'... kcrisman (May 23 '11)

I have a related question. Would it be possible to have variables with bars on them Something like this

rhobar=var('\bar{rho}')

Each time I use bar I cannot copy paste the latex output in my paper/document.

Your question should not be listed as an "answer" to the question on this page. Anyway: "var('rhobar', latex_name='\\bar{\\rho}')" does what you want, as does "var('rhobar', latex_name=r'\bar{\rho}')" John Palmieri (May 23 '11)
