Okay slight annoyance:
I'm compiling a component (shells_lain_commands_dirname) which uses
the contracts/command/default.nix contract:
{stdenv, buildFractalideContract, upkeepers
, tuple
, ...}:
buildFractalideContract rec {
src = ./.;
contract = ''
@0xdfa17455eb3bee21;
using Tuple = import "${tuple}/src/contract.capnp";
struct Command {
name @0 : Text;
singles @1 : List(Text);
kvs @2 : List(Tuple.Tuple);
}
'';
}
when I compile the shells_lain_commands_dirname I get this error:
[stewart@rivergod:~/dev/fractalide/fractalide]$ nix-build --argstr
debug true --argstr cache $(./support/buildCache.sh) -I
nixpkgs=/home/stewart/dev/fractalide/nixpkgs/ --argstr test true
--argstr subnet shells_lain_commands_dirname
...

*****************
but as soon as I remove the import from contracts/command/default.nix
{stdenv, buildFractalideContract, upkeepers
, ...}:
buildFractalideContract rec {
src = ./.;
contract = ''
@0xdfa17455eb3bee21;
struct Tuple {
first @0 : Text;
second @1 : Text;
}
struct Command {
name @0 : Text;
singles @1 : List(Text);
kvs @2 : List(Tuple);
}
'';
}
The program compiles perfectly well:
[stewart@rivergod:~/dev/fractalide/fractalide]$ nix-build --argstr
debug true --argstr cache $(./support/buildCache.sh) -I
nixpkgs=/home/stewart/dev/fractalide/nixpkgs/ --argstr test true
--argstr subnet shells_lain_commands_dirname
/nix/store/g62lg838n9sdhcl7qpi0yq311srmdaqc-shells_lain_commands_dirname
This is what shells_lain_commands_dirname looks like atm:
#![feature(question_mark)]
#[macro_use]
extern crate rustfbp;
extern crate capnp;
component! {
shells_lain_commands_dirname, contracts(generic_text, command)
inputs(stdin: generic_text),
inputs_array(),
outputs(stdout: generic_text),
outputs_array(),
option(command),
acc(),
fn run(&mut self) -> Result<()> {
let mut opt = self.recv_option();
{
let reader: command::Reader = opt.get_root()?;
let name = reader.get_name();
println!("the name: {}", name?);
for kv in reader.get_kvs()?.iter() {
let first = kv.get_first();
let second = kv.get_second();
println!("first: {}, second: {}", first?, second?);
}
for single in reader.get_singles()?.iter() {
println!("arg: {}", single?);
}
}
let mut ip_a = try!(self.ports.recv("stdin"));
{
let a_reader: generic_text::Reader = try!(ip_a.get_root());
let a = a_reader.get_text();
println!("{}", a?);
}
self.ports.send("stdout", ip_a);
Ok(())
}
}
Please advise.
