| nash | llnz: BTW... it would probably be a good idea to keep merging in the various rulesets to tpserver-cpp mainline whenever you can. | 01:59 |
| nash | Nip any conflicts in the bud early, and make it easier to test | 01:59 |
| llnz | nash: true, but it's harder to track who did what, though git should make that easy | 02:02 |
| llnz | i actually have a branch locally called "all" where i'm merging everything together | 02:02 |

| pluskid | mithro: almost fine | 08:17 |
| mithro | almost? | 08:17 |
| pluskid | I've ported pyscheme to schemepy interface | 08:17 |
| mithro | yeah, I saw the status report | 08:17 |
| pluskid | not every test case passed | 08:17 |
| pluskid | I have two task currently: | 08:17 |
| mithro | I also read your trampoline tail recusion blog post - yay google translate! | 08:17 |

| pluskid | We are having massive earthquake in China these days. :( | 08:18 |
| mithro | pluskid: yeah, it's been all over the news here | 08:19 |
| pluskid | I'm going to either: write benchmark/fix the dynamic wind problem. | 08:19 |
| mithro | pluskid: China's a pretty big place, was it anywhere near you? | 08:19 |
| pluskid | no | 08:19 |
| mithro | there is a bunch of benchmarking tools | 08:19 |
| pluskid | e.g ? | 08:19 |
| mithro | http://code.google.com/p/benchrun/ | 08:20 |
| tpb | Title: benchrun - Google Code (at code.google.com) | 08:20 |

| pluskid | mithro: OK, I'll look at that | 08:21 |
| mithro | the timeit module might be useful too | 08:21 |
| pluskid | yes, someone mentioned that to me the other day when I asked in our local BBS | 08:21 |
| mithro | just good old time.time() can also work :) | 08:21 |

| * llnz is writing email to people with compromised keys | 08:28 | |
| mithro | pluskid: Should test_string.py not include a string with unicode characters in it | 08:52 |
| pluskid | mithro: Do you mean unicode chars should be included in the test? | 08:53 |
| mithro | pluskid: I mean have a string which has unicode characters in the list of strings you test | 08:54 |
| pluskid | OK | 08:54 |
| mithro | IE "\u02345....." | 08:54 |
| pluskid | hehe, test failed | 08:54 |
| mithro | Test long also does not appear to check for scheme->python conversion of longs | 08:55 |
| mithro | (well not that the fromscheme is returning a real python long and not something which just happens to be equal to one) | 08:56 |
| pluskid | fromscheme is scheme->python test | 08:57 |
| pluskid | eval -> fromscheme | 08:57 |
| mithro | hrm? | 08:58 |
| pluskid | I mean, scheme->python conversion is tested when I eval a piece of scheme code and use fromscheme to convert it to get a Python long | 08:58 |
| mithro | should you not be asserting | 08:59 |
| mithro | type(vm.fromscheme(v)) == long | 08:59 |
| mithro | otherwise the value you get back could be an int or something else which could equal a long | 09:00 |
| pluskid | Oh | 09:00 |
| pluskid | I guess I checked | 09:00 |
| pluskid | assert m1.type(a) == long | 09:00 |
| mithro | type(vm.fromscheme(v)) == long is not equiv to vm.type(a) == long | 09:01 |
| pluskid | Oh, I see | 09:01 |
| pluskid | But why constrain the real type here? | 09:01 |
| mithro | you really should check both | 09:01 |
| pluskid | I think an int or long is both OK | 09:01 |
| pluskid | like test_int.py | 09:02 |
| mithro | if the vm.type(a) is a long, it should return a long - no? :) | 09:02 |
| pluskid | not really | 09:02 |
| pluskid | especially, | 09:02 |
| pluskid | if vm.type(a) is list | 09:02 |
| pluskid | it might return an instance of a sub-class of list | 09:03 |
| pluskid | sometimes there's even no suitable type | 09:03 |
| mithro | well check it's a subclass of int? | 09:03 |
| pluskid | like for a callable, or object | 09:03 |
| mithro | yeah - for the basic types it's more important | 09:04 |
| pluskid | Well, at lease type(vm.fromscheme(a)) in (int, long) should be true | 09:04 |
| pluskid | I'll add that | 09:04 |
| mithro | oh - something I have yet to suggest is I think we should support the python array interface for inplace array manipulation sharing | 09:05 |
| pluskid | array interface? | 09:05 |
| mithro | hrm - I think the above should be issubclass(vm.fromscheme(a), int) | 09:05 |
| mithro | Python has an array interface for interfacing to things like numpy | 09:06 |
| pluskid | so array interface to manipulate Scheme cons list directly? | 09:06 |
| pluskid | sometimes a Python int converted to Scheme and back, it will become a long | 09:07 |
| mithro | pluskid: why? -- sometimes a Python int converted to Scheme and back, it will become a long | 09:07 |
| pluskid | 2**23-1 can be int in Python, but not necessarily a fixnum in all Scheme implementation | 09:08 |
| mithro | well - most scheme implementations have a vector/array type | 09:08 |
| pluskid | array/vector: yes, I'm planning to support them | 09:08 |
| pluskid | that's why there might be a sub-class of Python list/dict | 09:08 |
| mithro | I think array/vector should map to any python type which supports the python-array interface | 09:09 |
| pluskid | I should remember whether it is converted from Scheme cons list or vector array | 09:09 |
| *** zzorn_laptop has quit IRC | 09:09 | |
| pluskid | I'd like it to map to a Python list | 09:09 |
| mithro | a cons list should go to a Python list | 09:10 |
| mithro | a vector array should probably go to a numpy type most of the time | 09:10 |
| mithro | does that make sense? | 09:10 |
| pluskid | numpy? is it available in Python standard library? | 09:10 |
| mithro | no - numpy is an addon | 09:11 |
| mithro | it provides support for large vectors of a single type | 09:11 |
| pluskid | then, in order to run schemepy, people will have to install numpy? | 09:11 |
| mithro | just as uint32 | 09:11 |
| mithro | pluskid: only if they want to make use of vectors | 09:11 |
| mithro | actually | 09:11 |
| mithro | if you use the array interface, they can use numpy for speed when avaliable and fall back to a start list when not | 09:12 |
| mithro | anyway - it's not high on our todo list at the moment | 09:12 |
| mithro | so I'll let you get back to your homework :) | 09:12 |
| pluskid | en | 09:12 |
| pluskid | already finished ;) | 09:13 |
| mithro | arn't you efficent | 09:13 |
| pluskid | not too many today. | 09:13 |
| mithro | oh - btw the python-array interface is a C interface | 09:13 |
| mithro | http://docs.python.org/lib/module-array.html | 09:14 |
| tpb | Title: 5.6 array -- Efficient arrays of numeric values (at docs.python.org) | 09:14 |
| pluskid | I'm wondering: is it constrained to put only objects of one type in a numpy array? But I guess scheme vector can hold any type of objects at a time | 09:14 |
| mithro | This module defines an object type which can efficiently represent an array of basic values: characters, integers, floating point numbers. Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. | 09:14 |
| mithro | a scheme vector can only hold on type of object | 09:15 |
| pluskid | OK, that's fine | 09:15 |
| mithro | oh wait | 09:16 |
| mithro | sorry | 09:16 |
| mithro | I have it wrong | 09:16 |
| mithro | vectors are fixed length lists | 09:16 |
| pluskid | hm | 09:16 |
| mithro | Vectors are sequences of Scheme objects. Unlike lists, the length of a vector, once the vector is created, cannot be changed. The advantage of vectors over lists is that the time required to access one element of a vector given its position (synonymous with index), a zero-origin number, is constant, whereas lists have an access time linear to the position of the accessed element in the list. | 09:16 |
| mithro | Vectors can contain any kind of Scheme object; it is even possible to have different types of objects in the same vector. | 09:16 |
| mithro | http://www.gnu.org/software/guile/manual/html_node/Vectors.html#Vectors | 09:16 |
| tpb | <http://ln-s.net/1rzA> (at www.gnu.org) | 09:16 |
| mithro | I was thinking of "Arrays" | 09:17 |
| mithro | http://www.gnu.org/software/guile/manual/html_node/Arrays.html#Arrays | 09:17 |
| tpb | <http://ln-s.net/1rzB> (at www.gnu.org) | 09:17 |
| mithro | Arrays are a collection of cells organized into an arbitrary number of dimensions. Each cell can be accessed in constant time by supplying an index for each dimension. | 09:17 |
| mithro | In the current implementation, an array uses a generalized vector for the actual storage of its elements. Any kind of generalized vector will do, so you can have arrays of uniform numeric values, arrays of characters, arrays of bits, and of course, arrays of arbitrary Scheme values. For example, arrays with an underlying c64vector might be nice for digital signal processing, while arrays made from a u8vector might be used to hold gray-scale images. | 09:17 |
| pluskid | hmm, array and vector is different in guile | 09:19 |
