Okay David, that worked well, not being able to compose contracts has
been a thorn in my side for a long time, this makes me very happy
indeed.
Thank you kindly.
This is the solution:
contracts/list/command/default.nix
{stdenv, buildFractalideContract, upkeepers
, command
, ...}:
buildFractalideContract rec {
src = ./.;
contract = ''
@0xf61e7fcd2b18d862;
using Command = import "${command}/src/contract.capnp";
struct ListCommand {
commands @0 :List(Command.Command);
}
'';
}
imports contracts/command/default.nix:
{stdenv, buildFractalideContract, upkeepers
, tuple
, ...}:
buildFractalideContract rec {
src = ./.;
contract = ''
@0xdfa17455eb3bee21;
using Tuple = import "${tuple}/src/contract.capnp";
struct Command {
name @0 : Text;
singles @1 : List(Text);
kvs @2 : List(Tuple.Tuple);
}
'';
}
which imports tuple:
{stdenv, buildFractalideContract, upkeepers
, ...}:
buildFractalideContract rec {
src = ./.;
searchPaths = [];
contract = ''
@0xf6e41344bb789d96;
struct Tuple {
first @0 : Text;
second @1 : Text;
}
'';
}
The trick as David said is to make the "project directory" to be "/"
by setting "-I /" in buildFractalideContract.nix:
{ stdenv, writeTextFile, capnproto, capnpc-rust, genName }:
{ src, contract, ... } @ args:
let
name = genName src;
contractText = writeTextFile {
name = name;
text = contract;
executable = false;
};
in stdenv.mkCachedDerivation (args // {
name = name;
unpackPhase = "true";
installPhase = ''
runHook preInstall
mkdir -p $out/src
cp ${contractText} $out/src/contract.capnp
${capnproto}/bin/capnp compile
-o${capnpc-rust}/bin/capnpc-rust:$out/src/ $out/src/contract.capnp -I
"/"
'';
})
[stewart@rivergod:~/dev/fractalide/fractalide]$ nix-build --argstr
debug true --argstr cache $(./support/buildCache.sh) -I
nixpkgs=/home/stewart/dev/fractalide/nixpkgs/ --argstr test true -A
contracts.list_command

\m/ perfect!
It would be neat if the language on the website reflected what David mentioned.
