My needs are pretty basic: read some values from a file, which is in a format familiar to many people (especially Windows administrators kind of people). So I can have a small tool that hooks up with an existing database and I can just tell the admin to "edit the .INI" and there's a good chance they'll feel right at home. Easy syntax, basically just a=b, not a lot of opportunities to screw up. The other options are to use the Lisp reader (problems with security, hard to get syntax right for non-lispers) and to invent some other format (what's the point when this one works well), so py-configparser seems perfect for me. I actually _do_ have one suggestion, although it's not directly related to the code and also may seem a little drastic :) , and that is to rename the library (maybe to something like just "configparser"). TBH, I don't see the point of "py-" part of the name. Of course, it's interface is (somewhat, I guess) modeled after python's module, but that warrants only a honorable mention in the docs, not the name. As it is, "py" in the name suggests for me some kind of "runtime" connection to python, which is misleading and actually unfair for a nice pure-lisp general-purpose library. There's also a chance that with the interface can be changed slightly (no, nothing specific, just that some patterns may emerge with usage that will be expressed easily in a more lispy way) and it's good not to be limited by the name. Of course that's not a serious issue, but if we are talking suggestions, I couldn't but mention it. And yes, that can happen in practice - I was actually mislead by the name and read it as "a library to parse (some sort of) configuration of python itself" at first, before having a look at it. Certainly, it could've been just me being dense :) Thanks, Ury

[py-configparser-devel] missing files treatment

Hi, It seems at the moment (version 1.0.2) if I specify some files that are not present I get an error in (read-files). Python's docs at http://docs.python.org/lib/RawConfigParser-objects.html state that "If a file named in filenames cannot be opened, that file will be ignored", which actually is very useful behavior. So, maybe I'll be possible to make a change in this, something like: diff -u -r py-configparser-1.0.2-orig/parser.lisp py-configparser-1.0.2/parser.lisp --- py-configparser-1.0.2-orig/parser.lisp 2008-03-16 01:05:40.000000000 +0200 +++ py-configparser-1.0.2/parser.lisp 2008-06-03 15:53:01.406250000 +0300 @@ -190,7 +190,7 @@ Returns as values the configuration and the list of files actually read."
