Re: [matplotlib-devel] How to decouple non-GUI stuff from the GUI?

If you use the MacOSX backend, you won't need pygtk, pycairo, pyqt, pygobject, wx, tcl/tk, or anything they depend on, which was my main motivation for writing this backend. Other than the fact that the MacOSX backend currently does not support the non-interactive mode, it should work for you, doesn't it? --Michiel. --- On Thu, 11/18/10, Kynn Jones <ky...@gm...> wrote: From: Kynn Jones <ky...@gm...> Subject: Re: [matplotlib-devel] How to decouple non-GUI stuff from the GUI?

Just to keep from ranting like a lunatic, basically. The experience was traumatic enough to shake my faith in Python altogether, and made me miss good ol' CPAN.

(I reiterate that the above is a barebone's summary. There's a lot that I'm omitting.) As an aside, I have never in my life seen a worse installation system than pycairo's. If you have not examined it in detail, please do so before reacting to my comments. In particular look at the waf file, and the files it invokes. Also, when you find the latter, do a global search for the number 1337 to get a whiff pycairo's excremental aroma. There is no point in choosing Python as one's programming language if this means that one depends on garbage like pycairo. I think it is unfair to put unsuspecting users of matplotlib through the ordeal of dealing with pycairo's installation. (And pygtk's and pygobjects's are not much better.) We can't force people to write good Python, but at the very least we should not propagate bad code. Packages like pycairo, pygtk, and pygobjects are substandard, and they should be ostracized by the rest of the Python community until they shape up. Even putting pycairo aside, the Python package installation system is a disaster. The problems I've summarized on this page are par for the course with Python packages. Just getting matplotlib to install (even without most interactive backends) was also a multi-day nightmare... You see? I'm ranting like a lunatic. Sorry. I'll stop. ~kj -----Inline Attachment Follows----- ------------------------------------------------------------------------------ Beautiful is writing same markup.
