Forking simplejson
Héllo, I would like to fork simplejson [1] and implement serialization rules based on protocols instead of types [2], plus special cases for protocol free objects, that breaks compatibility. The benefit will be a better API for json serialization of custom classes and in the case of iterable it will avoid a calls like: >>> simplejson.dumps(list(my_iterable)) The serialization of custom objects is documented in the class instead of the ``default`` function of current simplejson implementation [3]. The encoding algorithm works with a priority list that is summarized in the next table: +---+---+ | Python protocol | JSON | | or special case | | +===+===+ | (ø) __json__ | see (ø) | +---+---| | map | object| +---+---+ | iterable | array | +---+---+ | (*) float,int,long| number| +---+---+ | (*) True | true | +---+---+ | (*) False | false | +---+---+ | (*) None | null | +---+---+ | (§) unicode | see (§) | +---+---+ (ø) if the object implements a __json__ method, the returned value is used as the serialization of the object (*) special objects which are protocol free are serialized the same way it's done currently in simplejson (§) if the algorithm arrives here, call unicode (with proper encoding rule) on the object and use the result as json serialization As soon as an object match a rule, it's serialized. What do you think ? Do you find this API an improvement over simplejson ? Is it worth to code ? Where are documented the different protocols implemented by Python objects ?

Sure, but most of *everything* is Python 2.x, and porting to Python 3.x is already enough of a pain that key-stone projects like Trac still aren't there :) . This isn't going to be easily amenable to auto-translation via 2to3 (because you generally are calling log.warn() rather than logging.warning, but sometimes you are doing getattr( log, log_level ) and then passing that method around a few times), and it will often fall into the small percentage of untested code in most projects (coverage is often poor for logging messages in corner cases), so often won't get caught by test suites.

I'm not sure there's a good answer to that. If you're talking GUIs, windows, and extensible widgets, it really sounds like the kinds of things you're trying to do are going to require javascript.

Running pypiserver as a service? I'm writing some scripts which in theory should be able to: - start up a local pypi server as a daemon (or well a service on Windows) - run "python setup.py develop" on a potentially very big set of eggs, possibly discovering automatically for changes. In theory using develop changes should be automatically seen, but if I move/rename something of course things might not work anymore. - run/debug/develop applications using this big set of eggs. On the distutils list it was suggested to use the "-m" option to easy_install, which avoids writing on the global easy_install.pth, which is one of the current problems.

Bound methods also pull along to *which* log you are going to send the message, but then I suppose you could just use the logging key as well as a piece of data.

In the repr, yes. If you try printing the string, you'll see that it
only contains one \.
By the way, regular expressions are overkill here. You can use the
str.replace method for this:
>>> print(r'Silly \ " quote'.replace('\\', '').replace('"', r'\"'))
Silly \\ \" quote

If a string has a literal \, does it get shown as \\? I'd appreciate it if you cc me on the reply. Thanks. Ross Boylan I can't really help on the regex aspect of your code, but I can tell you a little about backslashes, quote literals, the interpreter, and python. First, I'd scrap the interpreter and write your stuff to a file. Then test it by running that file. The reason for that is that the interpreter is helpfully trying to reconstruct the string you'd have to type in order to get that result. So while you may have successfully turned a double bacdkslash into a single one, the interpreter helpfully does the inverse, and you don't see whether you're right or not. Next, always assign to variables, and test those variables on a separate line with the regex. This is probably what your document meant when it mentioned the result of a function. Now some details about python. When python compiles/interprets a quote literal, the syntax parsing has to decide where the literal stops, so quotes are treated specially. Sometimes you can sidestep the problem of embedding quotes inside literals by using single quotes on the outside and double inside, or vice versa. As you did on the 'Silly " quote' example. But the more general way to put funny characters into a quote literal is to escape each with a backslash. So there a bunch of two-character escapes. backslash-quote is how you can put either kind of quote into a literal, regardless of what's being used to delimit it. backslash-n gets a newline, which would similarly be bad syntax. backslash-t and some others are usually less troublesome, but can be surprising. And backslash-backslash represents a single backslash. There are also backslash codes to represent arbitrary characters you might not have on your keyboard. And these may use multiple characters after the backslash. So write a bunch of lines like a = 'this is\'nt a surprise' print a and experiment. Notice that if you use \n in such a string, the print will put it on two lines. Likewise the tab is executed. Now for a digression. The interpreter uses repr() to display strings. You can experiment with that by doing print a print repr(a) Notice the latter puts quotes around the string. They are NOT part of the string object in a. And it re-escapes any embedded funny characters, sometimes differently than the way you entered them. Now, once you're confident that you can write a literal to express any possible string, try calling your regex. print re.sub(a, b, c) or whatever. Now, one way to cheat on the string if you know you'll want to put actual backslashes is to use the raw string. That works quite well unless you want the string to end with a backslash. There isn't a way to enter that as a single raw literal. You'd have to do something string like a = r"strange\literal\with\some\stuff" + "\\" My understanding is that no valid regex ends with a backslash, so this may not affect you. Now there are other ways to acquire a string object. If you got it from a raw_input() call, it doesn't need to be escaped, but it can't have an embedded newline, since the enter key is how the input is completed. If you read it from a file, it doesn't need to be escaped. Now you're ready to see what other funny requirements regex needs. You will be escaping stuff for their purposes, and sometimes that means your literal might have 4 or even more backslashes in a row. But hopefully now you'll see how to separate the different problems. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list

I don't know about that. Best practices are often best for everyone; it's more critical for a bank than for a game server, but that doesn't mean the game server can afford to use swiss cheese as armor plate.

OK, lets start a framework in using python in the server side and the client side. (1). requirements of the server side first: 1. sending HTML, XML documents to be displayed in the browsers of the clients and receiving for user inputs are easy in modpython, django, and etc. 2. Data received in the server side has to be stored and verified for later accesses performed from client's requests 3. data and traffic amounts to be estimated for the server in order to process requests in terms of numbers of clients and costs per defined operation period, well, a slow database engine that consumes a lot CPU time in the server really sucks! (2). Lets check the client side, too! In scenario 1 the client side has the browser operating only via port 80. In scenario 2 the client side has an AP. that could be invoked in the browser, e.g. Adobe PDF reader or Apple's quick time engine In scenario 3 AP. can invoke the browser to a cyber page in the client side with multiple sockets via TCPIP/UDP of various ports in the AP., e.g. skype, msn, and etc.. Assuming that programmers can use a customized python package installed in the AP. of the client side with other tools is allowed. -- http://mail.python.org/mailman/listinfo/python-list
