13:39 dented42: I'm playing around with macros. The datum->syntax function takes a 'context' as it's first argument, which must be a syntax object. I don't really understand what that means, could someone enlighten me?
13:41 eli: greghendershott: (BTW, if you say my name here, my bot notifies me...)
13:41 jonrafkind: dented42, you have to imbue the syntax object with lexical context so thats what the first argument is
13:41 eli: dented42: Think about syntax objects as s-expression with "some lexical context"
13:42 eli: dented42: And that's in scare-quotes since you don't have any real access to that extra information, so the way you use it is by copying it from other syntax objects.
13:45 greghendershott: eli: Do you mean you'd prefer I not "eli:" you because the notifications are unwelcome, or are you just saying FYI that it won't go overlooked?
13:54 dented42: right
13:54 dented42: but what's it 'mean' ?
13:55 dented42: the guide has an example where the context is #'lex
13:55 dented42: but why not #'(1 2 3) ?
13:57 dented42: eli: so you mean that the context argument isn't the context itself, it's a syntax object from which to copy the context?
13:58 eli: greghendershott: No, that's fine -- I'm just saying that calling me doesn't fall on deaf ears.  (Only it comes as one message that plops into the pile of other 3k emails...)
13:59 eli: dented42: You should see where lex appears in the pattern -- so using #'lex means that you take *that* piece of syntax's lexical context.  If you'd write #'(1 2 3) then you'd be creating a new syntax object so the lexical context would be the one from the macro call, which is rarely what you'd want.
14:01 dented42: oh, ok
14:03 dented42: is there a way to extract a context from a syntax object? (something like syntax->context)
14:05 asumu: dented42: you can't really do anything with a context, so no. Anything that needs a context takes a syntax object.

14:14 greghendershott: eli: Thanks again for the report re tasks.v1.js. I found and fixed the problem. Will log and push. However fixing that uncovered another issue. The Google Tasks API has something relatively unusual — use of the HTTP "PATCH" method. That's not one of the fab four (GET, PUT, POST, DELETE) supported in net/url AFIK.
14:16 greghendershott: I guess I'll code up my `patch-pure-port' to use in the GAPI lib, and then try to loop back and prep a merge request to add `patch-(im)pure-port' functions to net/url.

If it did, I could write a two-line wrapper as an interim thing until it were added to net/url officially. But instead I'll have to duplicate a lot of that functionality in my lib.
14:50 greghendershott: I suppose it would be wrong to force net/url to provide it by way of rackunit's `require/expose', huh? :)
14:51 eli: Well, if you patch the code, and if I'm guessing right that it's going to be simple enough that there will be no questions, then something like that `require/expose' should be a fine hack with a big comment above it saying that this will go away with the next release...

Although real-world servers can be OK getting some 1.1 features in a request with a 1.0 version, it's not exactly correct, and I'm not sure about PATCH. In fact the real-world server motivating this — Google's Task API service — _doesn't_ seem happy getting "PATCH /foo HTTP/

22:19 blahgarbl: I'm not entirely sure of the scope of things, but can I ask questions about 2htdp libraries?
22:19 asumu: Sure.
22:20 blahgarbl: I may only have one question really
22:20 blahgarbl: and that is, how to get rid of that pesky sub-pixel rendering on diagonal lines
22:20 blahgarbl: and other stuff too I guess
22:21 blahgarbl: or is that just an implementation thing that cannot be changed
22:21 blahgarbl: actually I guess subpixel rendering isn't the right word, but hopefully you know what I mean
22:21 asumu: My guess is that it's an implementation thing. Do you have an example?
22:21 asumu: ISTR there was a discussion on the mailing list about this.
22:22 blahgarbl: well they're just basic lines
22:22 blahgarbl: like (line 50 50 'red)
22:22 asumu: Oh is this where it draws different thicknesses?
22:22 asumu: Depending on pixel alignment?
22:22 blahgarbl: yeah
22:22 blahgarbl: I figured it out for horizontal and vertical lines
22:23 blahgarbl: basically I have to place them at XXX.5 pixel locations
22:23 blahgarbl: but that doesn't help for diagonals

22:25 asumu: I think that explains the design.
22:28 blahgarbl: yeah that explains why it happens
22:28 blahgarbl: which more or less agrees with my preconception of why it happens
22:28 blahgarbl: but is there any way to "fix" it?
22:28 asumu: Oh okay. Well, apparently it is a design decision, so I don't think so.
22:28 asumu: You might ask on the mailing list though.
