| mncharity | so the elf sources have been using the wrong twigil for contextual variables, extensively, forever, and no-one noticed? sigh. sooo need code reviews. | 00:52 | |

| Auzon | mncharity: What do you mean? | 01:05 | |
| mncharity | context variables are $+foo, not $^foo. having someone look at the code and ask "what is wrong here?" might have caught it earlier. | 01:07 | |
| no biggie, just a startling thing to have wrong. | 01:08 | ||
| Auzon | oh. I thought you meant compiler vars ($?WHATEVER) | ||
| mncharity | ah, no | 01:09 | |

| mncharity | TimToady: I note the word "context" is used both for the void/scalar/list concept, and the completely unrelated $+ dynamic scoping concept. This is bad. | 01:12 | |
| Really bad. Not even "isn't best practices" bad. Shudder. | 01:24 | ||

| mncharity | in the real world, they are called "dynamically scoped". Not a great name, a historical artifact, but if we want to come up with a better one... we need a better one. | 01:51 | |
| or am I completely confused about what $+ means... | 01:55 | ||
| :/ | |||
| pmichaud | I think the term "contextual variable" may come from how they're often used. For example, in STD.pm the $+ variables are used to indicate a "context" to various subrules that are called. | ||
| thus list context, item context, etc. are just examples of possible contexts | 01:56 | ||
| mncharity | eep. so "context" from 'calling context'... interesting... | 02:00 | |
| pmichaud | it took me a while to understand that also. | ||
| and I'm not sure my interpretation is the same as TimToady's -- that's just what made sense to me. | 02:01 | ||
| mncharity | neat. that does make sense. my thanks. | 02:03 | |

| pmichaud | I had never used the return value of 'push' in p5 :-) | 12:38 | |
| pmurias | neither did i | 12:39 | |
| ;) | |||
| moritz_ | but in p5 it's nonsense to return an array because you can't access push as a method call | ||
| so no chained method calls at all | 12:40 | ||
| pmichaud | right. | ||
| moritz_ | so returning self might be sensible, so you can do things like @list.push(3, 4).sort() | ||
| bacek__ | pmichaud, moritz_ +1 | 12:41 | |
| pmichaud | afk for a bit | 12:44 | |
| pmurias | @list.push(3,4).sort() is a bit confusing | 12:48 | |

| moritz_ | pmurias: depends on your background ;) | ||
| pmurias | moritz_: you use a lot of jQuery? | 12:50 | |
| moritz_ | pmurias: no ;) | ||
| but I do chain methods with side effects | 12:51 | ||

| pmurias: ah, ok. | 21:30 | ||
| pmurias | there are lack of them is the most common occuring hack, and it will be more work if it's done later | 21:31 | |
| should i move $*emitter and $*parser as $*compiler attribiutes? | 21:33 | ||
| mncharity | sigh. the gotcha is, how to handle sub calls with multiple argument apis. an out of band scalar ('$X::x=0;f(...)' where 'sub f{if(not($X::x)){}elsif($X::x == 1){...named...}else{...full capture objects...}...}') is the fastest technique I found, but massively uglifies the code. no '$x->foo(...)->bar(...)', have to potentially assign X::x on each call. | ||
| pmichaud | pugs: my %hash = 1..6; say %hash; | 21:34 | |
| exp_evalbot | OUTPUT[1 23 45 6] | ||
| pmurias | we can use $foo->foo_named and $foo->full_capture_object and $foo->positional | 21:35 | |
| mncharity | next up is adding an argument to @_. putting at the beginning is slightly faster than at end, but breaks "sub and method call @_ look the same". so... ah well. f(args ,0) for now, with f(args, {named hash},1) for named. | ||
| pmurias | $foo->foo_NAMED, $foo->foo_CAPTURE, $foo->foo_POSITIONAL is what i meant | ||
| mncharity | hmm... | 21:36 | |
| pmurias | any issues? | 21:38 | |
| mncharity | so f(x) stays f(x) for positionals, but becomes &f->foo_blah() for blah. hmm. | ||
| &f->blah performance will be poor, but with named args, it already is. | 21:39 | ||
| you realize elf itself won't be able to use "we didn | |||

|

| mncharity | 't manage to compile them away" named args very much, or performance will collapse... | 21:39 | |
| pmurias | mncharity: f(x=>1) will be f_NAMED(...) | 21:40 | |
| mncharity | that would require having multiple copies of functions attached to different names... I was hoping to avoid that. | 21:41 | |
|
21:42
jferrero joined
|
|||
| pmurias | not a big problem, namespace items are cheap | 21:42 | |
| f_NAMED will call to f with the right arguments to prevent code duplication if that is what worries you | 21:43 | ||
| mncharity | I am still unclear on the consequences of the choice, and since it's not KISS, I fear it. | ||
| TimToady | what does a referece to a function look like then? | ||
| pmurias | \&foo_CAPTURE would be the most generic one | 21:44 | |
| mncharity | re 'call to f', yeah. autobox can define {package CODE; sub NAMED { $X::x=1; my $self=shift; goto $self; }} or some such. | ||
| pmurias | \&foo_NAMED and \&foo_POSITIONAL being the slightly "unboxed" ones | ||
| mncharity: don't use $X::x | 21:45 | ||
| mncharity | re 'what does a referece to a function look like then?', yeah... multiple functions-- | 21:46 | |
| pmurias | function should be stored in $scalars anyway | ||
| mncharity | re 'don't use $X::x', then how does f know how it is being invoked? ie, what @_ actually contains? | ||
| pmurias | f is allways invoked with positionals | 21:47 | |
| * always | |||
| f_NAMED gets named arguments and positionals | |||
| f_CAPTURE gets captures | |||
| mncharity | re 'function should be stored in $scalars anyway', the design choice of what a function looks like at runtime is independent of of where you put it. | ||
| pmurias | yes | ||
| true | 21:48 | ||
| mncharity | re separate f, f_N, f_C, see ^^^ 'what does a referece to a function look like then?' | ||
| pmurias | probably f_C | ||
| as it's the most generic one | |||
| mncharity | and 10+x slower. | 21:49 | |
| pmurias | you can always unbox it | ||
| $foo->i_want_the_positional_variant | |||
|
21:49
braceta left
|
|||
| mncharity | that brings us back to sub CODE::i_want_the_positional_variant. | 21:50 | |
| pmurias | using f and ->i_want_the_capture_variant is also an option | ||
| mncharity | that's the {package CODE; sub NAMED { $X::x=1; my $self=shift; goto $self; }} | 21:51 | |
| pmurias | but you don't pay extra cost on the positional varaint | ||
| * variant | |||
| mncharity | right. that's definitely a design objective. | ||
| the if(not($X::x)){} is fairly cheap. | 21:52 | ||
| pmurias | but it's ugly | ||
| mncharity | it's in the emitted code. Ugly is having them in front of every call, making it hard to read. It adds nothing to the 'unpack named args' ugliness it will preceed at the top of sub defs. | 21:53 | |
| I definitely prefer your f->NAMED(...) to both f->(...,0) and $X::x-0;f->(...) . | 21:55 | ||
| *$X::x=0;f->(...) | |||
| pmurias | i'll be away for the weekend at a lake with my classmates, but i can implement it afterwards (j2me can wait) | ||
| mncharity | ok, or i. I actually sketched and was debugging the (...,0) variant, but it was just so "didn't feel like the Right Thing". this is much better. | 21:56 | |
| sub's stay fast, and even simple in line named hash handling takes more time than the extra subcall. | 21:57 | ||
| pmurias | can you wait a few days, or do you need it badly? | ||
| mncharity | can wait. not like there isn't a lot else to do. :) | 21:58 | |
