This allows you to pass a thread directly into khan, instead of passing
a filename. This has several implications:
- The friction for using threads from an app is significantly lower.
Consider:
=/ shed
=/ m (strand ,vase)
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>('hi'))
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>('there'))
(pure:m !>('product'))
[%pass /wire %arvo %k %lard %base shed]
- These threads close over their subject, so you don't need to parse
arguments out from a vase -- you can just refer to them. The produced
value must still be a vase.
++ hi-ship
|= [=ship msg1=@t msg2=@t]
=/ shed
=/ m (strand ,vase)
;< ~ bind:m (poke:strandio [ship %hood] %helm-hi !>(msg1))
;< ~ bind:m (poke:strandio [ship %hood] %helm-hi !>(msg2))
(pure:m !>('product'))
[%pass /wire %arvo %k %lard %base shed]
- Inline threads can be added to the dojo, though this PR does not add
any sugar for this.
=strandio -build-file %/lib/strandio/hoon
=sh |= message=@t
=/ m (strand:rand ,vase)
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>('hi'))
;< ~ bind:m (poke:strandio [our %hood] %helm-hi !>(message))
(pure:m !>('product'))
|pass [%k %lard %base (sh 'the message')]
Implementation notes:
- Review the commits separately: the first is small and implements the
real feature. The second moves the strand types into lull so khan can
refer to them.
- In lull, I wanted to put +rand inside +khan, but this fails to that
issue that puts the compiler in a loop. +rand depends on +gall, which
depends on +sign-arvo, which depends on +khan. If +rand is in +khan,
this spins the compiler. The usual solution is to either move
everything into the same battery (very ugly here) or break the
recursion (which we do here).
We had trie operations independently implemented in +de in arvo,
+an:cloy in zuse, +zu in clay, lib/trie, and app/spider. This unifies
them all into +de in arvo, aggregating the used operations.
addresses #5442 by adding %thread-done and %thread-fail marks. also
fixes await-thread:strandio and removes some blank lines from
app/spider.hoon
%thread-done loses the type of the result, so you'll need to use ;; to
get it back. the real way to fix this is to have threads produce cages
instead of vases
