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).
