| 02:40 | <&ToxicFrog> | Hrm. |
| 02:40 | <&ToxicFrog> | so at the moment, some degree of lexing happens in readline(), and some in run_string() |
| 02:41 | <&ToxicFrog> | In particular readline() strips out comments to save room in the input buffer, which on the AVR was quite small |
| 02:42 | <&ToxicFrog> | This is kind of ugly and means that readline() ends up having more intelligence than I'd like, e.g. it has to know if it's inside a string or not |
| 02:43 | <&ToxicFrog> | Earlier builds just read individual characters into the lexer directly, but this meant words would execute as you typed them, which was disconcerting at best and could lead to garbled output if the words being executed outputted their own stuff to the tty. |

| 03:01 | <&ToxicFrog> | So now I'm wondering if I want something like a "command buffer". Making it 80b lets it store 40 instructions, which is at least as good as the 80b input buffer |
| 03:02 | <&ToxicFrog> | There's no separate input buffer, the lexer drops comments and handles everything else directly, appending operations to the command buffer |
| 03:03 | <&ToxicFrog> | In effect it compiles the user input into an anonymous funHOLY SHIT |
| 03:03 | < Jessikat> | ? |
| 03:03 | <&ToxicFrog> | I could implement this just by running the normal compilation code, executing the resulting function, and then freeing it |
| 03:03 | < Jessikat> | Ah |
| 03:04 | <&ToxicFrog> | That does have a bunch of overhead, though |
| 03:04 | <&ToxicFrog> | Has to malloc() up a few things, etc |
| 03:05 | <&ToxicFrog> | just writing to a static opcode buffer and then passing it to execute_wordlist() when either it runs out of room or we reach EOL may be better. |
| 03:06 | <&ToxicFrog> | It would let me ditch the distinction between compile mode and run mode, though...hrm |
| 03:39 | <&ToxicFrog> | (or, well, not completely, but the difference then becomes "upon returning to run mode, pop the function on top of the stack, execute it, free it, then go back into compile mode") |
| 03:39 | <&ToxicFrog> | I think this needs more sleep and more rubber ducking. |
| 03:39 | <&ToxicFrog> | And perhaps implementing multiline strings in the meantime. |

| 12:57 | <~Vornicus> | So I was, the other day, talking to someone about the dangers of mutating a list while iterating over it - how, absent certain protections, you may find yourself accidentally skipping things you have to deal with. |
| 12:58 | <~Vornicus> | This was in the context of the sieve of eratosthenes, which in one particular formulation works by deleting numbers that are divisible by known primes. |
| 13:01 | <~Vornicus> | Turns out most of the time in this particular application, the mutation is fine: you don't typically eliminate two consecutive candidate primes anyway, there's almost always something in between. |
| 13:01 | <~Vornicus> | ...almost. |
| 13:02 | <~Vornicus> | I asked in freenode ##math whether it exists, and a day & change later somebody found one. |
| 13:02 | <~Vornicus> | The one he found was 421 digits long. |
| 13:13 | <@TheWatcher> | Eeesh |
| 13:14 | <~Vornicus> | there's probably smaller, but the very existence of this thing is delicious. |

| 15:45 | < Jessikat> | ...i want to work, but my mind is stuck composing a blog entry |
| 15:45 | <&ToxicFrog> | Ooo I hate it when that happens |
| 15:48 | <&[R]> | Jessikat: write down the idwas you have for it, then you'll have at least appeased that idea |
| 15:48 | < Jessikat> | Already did that |
| 15:48 | < Jessikat> | Just clarified things so more thought could happen |
| 15:49 | < Jessikat> | It's a really interesting post as well |
| 15:49 | < Jessikat> | At least I've got a few code reviews done |
