| 00:23 | < MyCatVerbs> | AAAAA, POSTSCRIPT! |
| 00:23 | <@ToxicFrog> | dup copies the top stack element, exch swaps the top two stack elements, and roll rotates the top n stack elements. |

| 00:24 | <@ToxicFrog> | Using those you can also implement insert and suchlike. |
| 00:24 | <@ToxicFrog> | Wibblies, Chalcy. |
| 00:24 | <@Vornicus-Latens> | ooh, index |
| 00:24 | <@Chalcedon> | hello |
| 00:25 | <@Vornicus-Latens> | ...I'm not quite sure I understand roll. |
| 00:26 | | Vornicus-Latens is now known as Vornicus |
| 00:26 | <@ToxicFrog> | The examples are unclear? |
| 00:27 | <@ToxicFrog> | Basically, it shifts the top n stack elements left or right, and ones that drop off one side are placed on the other side. |
| 00:27 | <@Vornicus> | oh, oh, oh, I seeeeee |
| 00:27 | <@Vornicus> | okay, let's see what order I need these operands in. |
| 00:31 | <@Vornicus> | hey, that worked |
| 00:31 | < gnolam> | Forth? |

| 00:32 | < gnolam> | Ah. The commands seem identical. :) |
| 00:32 | < gnolam> | (I've never really looked into PostScript) |
| 00:32 | <@Vornicus> | For good reason, they're both RPN languages. |
| 00:36 | | * Vornicus tries to figure out if he can pass parameters into a script. |
| 00:37 | <@ToxicFrog> | As in, from bash? |
| 00:37 | <@Vornicus> | yeah |
| 00:37 | <@ToxicFrog> | stoatburgers.bash does this |
| 00:37 | <@Vornicus> | I want to pass (for instance) the size I'm renderi-- ooh, let me seee. |

| 00:37 | <@ToxicFrog> | http://www.funkyhorror.net/toxicfrog/projects/stoatburgers.bash |
| 00:38 | <@ToxicFrog> | The interesting bit is all the -dfoo=$bar lines at the end |

| 00:55 | <@ToxicFrog> | Which stack manipulation? |
| 00:55 | <@Vornicus> | I'm trying to take two items off the stack, multiply them by a scaling factor, put them into an array, then put the array into a dictionary. I think I have it. |
| 00:57 | <@ToxicFrog> | Hrm. |

| 01:14 | <@Vornicus> | I wish I could get it to print everything it's doing out. |

| 01:24 | <@ToxicFrog> | Also == |
| 01:24 | <@ToxicFrog> | I forget the difference, though. |
| 01:25 | <@Vornicus> | == is like __repr__ to ='s __str__, or some such, apparently |
| 01:29 | <@ToxicFrog> | Neither of which I am familiar with. |
| 01:32 | <@Vornicus> | from Python - str will present something human readable, usually, and __repr__ usually follows the contract of eval(repr(foo)) == foo |
| 01:34 | <@Vornicus> | ...oh, oops, that would do it. |
| 01:34 | <@ToxicFrog> | Aah. |
| 01:34 | <@ToxicFrog> | __str__ is like Lua's __tostring |
| 01:34 | <@ToxicFrog> | I don't think it has an equivalent to __repr__, although it's easy enough to make one. |
| 01:34 | | * Vornicus figures it out - he thought put returned the thing you're putting into, for some reason. |
| 01:36 | <@Vornicus> | there. |

| 01:45 | <@Vornicus> | I didn't know that showpage was the thing that commited stuff to the page, so I've been apparently working without output. |
| 01:45 | <@Vornicus> | Apparently the greyscale bug is still in 8.54 |
| 01:45 | <@ToxicFrog> | ...oops |
| 01:45 | <@ToxicFrog> | What greyscale bug? |
| 01:45 | <@Vornicus> | If I declare the size inside the postscript file, the way I've been doing, it switches to greyscale. |
| 01:47 | <@Vornicus> | And I don't know how to switch it back |
| 01:48 | <@ToxicFrog> | ...weirdness. |
| 01:48 | <@ToxicFrog> | setcolorspace doesn't do it? |

| 03:30 | <@Vornicus> | Setting the ProcessColorModel doesn't help, either. what the hell is this thing on, anyway? |
| 03:34 | <@ToxicFrog> | Umm. |

| 04:17 | <@ToxicFrog> | Oh? |
| 04:19 | <@Vornicus> | It looks like setpagedevice resets the color space. |
| 04:19 | <@Vornicus> | to the default, which is DeviceGray |
| 04:26 | <@ToxicFrog> | Aah. |
| 04:26 | <@ToxicFrog> | So why doesn't setcolorspace switch it back? |
| 04:26 | <@ToxicFrog> | And what does? |
| 04:27 | <@Vornicus> | Setcolorspace does switch it back, apparently, I think I had an ordering problem earlier. |

| 04:58 | <@ToxicFrog> | 140 New Zealand dollars = 115.098276 Canadian dollars |
| 05:00 | <@McMartin> | conv tracks exchange rates? |
| 05:01 | <@ToxicFrog> | Yep. |

| 05:02 | < Reiver> | Yeah. |
| 05:02 | <@ToxicFrog> | McMartin: or, rather, Google does. |
| 05:02 | < Reiver> | They do that. |
| 05:02 | < Reiver> | It tends to fluctuate. |
| 05:02 | <@ToxicFrog> | Since conv is just grep wrapped around curl wrapped around google. |

| 06:13 | <@Vornicus> | ...okay, how do I draw an ellipse with a constant line width? |
| 06:13 | < Mahal> | =blink pardon=? |
| 06:15 | <@Vornicus> | I'm working in PostScript. I have a command that I can call to get a circle, and in order to get an ellipse from it I need to change the user transformation, which means that the lines will be thinner or thicker depending on the direction of the line. |
| 06:16 | <@ToxicFrog> | Umm. |
| 06:16 | <@ToxicFrog> | I think you have to use curveto. |
| 06:17 | <@ToxicFrog> | Although it may be possible to use arc and then some kind of abuse of the path before you call stroke... |
| 06:17 | <@Vornicus> | gner |
| 06:17 | <@ToxicFrog> | Postscript does have some odd gaps. |
| 06:17 | <@ToxicFrog> | Such as the lack of most of the trig functions. |
| 06:17 | <@Vornicus> | I see this. |
| 06:17 | <@ToxicFrog> | Only the ones needed to implement the others in terms of those are provided. |
| 06:18 | <@Vornicus> | cripes. |
| 06:19 | <@ToxicFrog> | http://www.redgrittybrick.org/postscript/ellipse.html |
| 06:20 | <@ToxicFrog> | Two implementations: the one the left uses matrix swaps, the one on the right, curveto. |
| 06:22 | | * Vornicus wonders why it is missing these thngs. |
| 06:24 | <@ToxicFrog> | Well. You are meant to be able to fit an entire postscript terp on a printer. |
| 06:24 | <@Vornicus> | Point. |
| 06:25 | <@ToxicFrog> | Less of an issue now, but earlier? Better to have fewer operators and generate more verbose code and take a bit longer to print than to have more operators but a terp that won't fit on half the common printers. |
| 06:32 | <@Vornicus> | there. |
| 06:32 | <@Vornicus> | okay. |
| 06:33 | <@ToxicFrog> | One thing I can't seem to figure out how to do is get gs to automatically load some postscript files when it starts. |
| 06:34 | <@ToxicFrog> | I have to manually include all my pet functions. |
| 06:34 | <@Vornicus> | I think there's a gs_somethingorother file that it automatically loads |
| 06:35 | <@Vornicus> | Look in the manual for "initialization files" |

| 19:45 | <@jerith> | So, bug tracking systems. Any preferences? |
| 19:46 | <@jerith> | I haven't yet found one that I like enough to use by choice. |

| 20:51 | <@ToxicFrog> | jerith: I like bugzilla, but I'm going mainly by CacheZilla, which is heavily modified. |
| 20:51 | <@jerith> | Bugzilla's overkill and thus painful. |
| 20:52 | <@jerith> | (Too much to wade through to get to the bits I want.) |
| 20:52 | <@jerith> | Trac's a bit too buggy for me. |
| 20:52 | <@jerith> | But I've heard good things otherwise. |
| 20:53 | <@jerith> | (I've also heard the the quality of its code is second only to portage in the getitoffme! rankings.) |
| 20:54 | <@jerith> | (Well, for Python code anyway.) |

| 21:22 | | * ToxicFrog ponders this problem |
| 21:22 | <@ToxicFrog> | Sigma = { a, b } |
| 21:23 | <@ToxicFrog> | Write an unambiguous CFG for { w | the count of a's and b's in w are equal } |
| 21:23 | < gnolam> | "C is a good, firm, well defined language. C++ is like, after C died, they dug it up, and attached some bolts to its neck, and it accidentally killed a little girl, and lived in a barn, with a friendly blind man... And the villagers chase it around sometimes with pitch forks." |
| 21:23 | <@ToxicFrog> | The obvious solution is W -> a W b W | b W a W | epsilon |
| 21:24 | <@ToxicFrog> | But I don't think that's unambiguous. |
| 21:25 | <@ToxicFrog> | No, it's not |
| 21:25 | <@ToxicFrog> | Because abab can be either (ab)(ab) or (a(ab)b) |

| 23:21 | <@ToxicFrog> | Argh. |
| 23:22 | <@ToxicFrog> | I need to write a turing machine that accepts the language { w1#w2 | w1 < w2 && w1,w2 e {0,1}* } |
| 23:22 | <@ToxicFrog> | Basically, you feed it "lhs#rhs" where lhs and rhs are binary numbers and it accepts if lhs < rhs. |
| 23:22 | <@ToxicFrog> | Which is trivial if lhs and rhs are of different lengths, but this is not guaranteed here. |
| 23:23 | <@ToxicFrog> | Hmm. I might have it, but it's ugly. |

| 23:48 | <@Vornicus> | Eventually, I hosed the installation with careless use of conflicting software installs and other silly uses of sudo that shouldn't have been available to a noob like myself, and I found myself using a HD install of Knoppix, which lead to a pure Debian install (from the tiny network install CD, which is really cool) before landing in my current distribution of choice, Ubuntu (which is an ancient African word that means "can't install Debian.") |
