aqua: show types in an Aqua-compatible way

Shows all data types defined in a Marine module in the Aqua-compatible way:

sh
marine help aqua
USAGE:
    marine aqua [OPTIONS] <in-wasm-path>
OPTIONS:
    -i, --id <service-id>           optional service id
    -s, --service <service-name>    optional service name
ARGS:
    <in-wasm-path>    a path to a Wasm file

sh
marine help aqua
USAGE:
    marine aqua [OPTIONS] <in-wasm-path>
OPTIONS:
    -i, --id <service-id>           optional service id
    -s, --service <service-name>    optional service name
ARGS:
    <in-wasm-path>    a path to a Wasm file

sh
marine aqua -i TestServiceId -s TestServiceName artifacts/records_effector.wasm
module TestServiceName declares *
data TestRecord:
  field_0: bool
  field_1: i8
  field_2: i16
  field_3: i32
  field_4: i64
  field_5: u8
  field_6: u16

  field_8: u64
  field_9: f32
  field_10: f64
  field_11: string
  field_12: []u8
service TestServiceName("TestServiceId"):
  mutate_struct(test_record: TestRecord) -> TestRecord

sh
marine aqua -i TestServiceId -s TestServiceName artifacts/records_effector.wasm
module TestServiceName declares *
data TestRecord:
  field_0: bool
  field_1: i8
  field_2: i16
  field_3: i32
  field_4: i64
  field_5: u8
  field_6: u16
  field_7: u32
  field_8: u64
  field_9: f32
  field_10: f64
  field_11: string
  field_12: []u8
service TestServiceName("TestServiceId"):
  mutate_struct(test_record: TestRecord) -> TestRecord

build: compile Marine module

Compiles Rust project to a Marine Wasm module. Under the hood, it calls cargo build providing all given arguments, then compiles and embeds interface-types to compiled Wasm binary.

sh
marine help build
USAGE:
    marine build [optional]...
ARGS:
    <optional>...    cargo build arguments

sh
marine help build
USAGE:
    marine build [optional]...
ARGS:
    <optional>...    cargo build arguments

generate: generate Marine project templates

Uses the power cargo-generate to generate a new project from this template. Note that cargo-generate should be installed (by cargo install cargo-generate) to use this subcommand.

sh
marine help generate
USAGE:
    marine generate [FLAGS] [OPTIONS]
FLAGS:
    -i, --init       generate the template into the current dir without creating a new one
OPTIONS:
    -n, --name <generate-project-name>    a project name; if the name isn't in kebab-case, it'll be converted to kebab-
                                          case

sh
marine help generate
USAGE:
    marine generate [FLAGS] [OPTIONS]
FLAGS:
    -i, --init       generate the template into the current dir without creating a new one
OPTIONS:
    -n, --name <generate-project-name>    a project name; if the name isn't in kebab-case, it'll be converted to kebab-
                                          case

info: prints embedded into Wasm file info

The marine_manifest macro embeds some info into compiled Wasm module that could be obtained with this command:

sh
marine info artifacts/greeting.wasm
it version:  0.23.0
sdk version: 0.6.0
authors:     Fluence Labs
version:     0.1.0
description: The greeting module for the Fluence network
repository:  https://github.com/fluencelabs/marine/tree/master/examples/greeting
build time:  2022-04-12 18:16:34.487366668 +00:00 UTC

sh
marine info artifacts/greeting.wasm
it version:  0.23.0
sdk version: 0.6.0
authors:     Fluence Labs
version:     0.1.0
description: The greeting module for the Fluence network

build time:  2022-04-12 18:16:34.487366668 +00:00 UTC

it: shows interface-types of the Wasm binary

Interface-types are embedded into a custom section of a Wasm binary while building with marine build

sh
marine it artifacts/greeting.wasm
(@interface it_version "0.23.0")
;; Types
(@interface type (func
  (param $size: i32)
    (result i32)))   ;; 0
...
;; Exports
(@interface export "allocate" (func 0))
(@interface export "release_objects" (func 1))
...
;; Implementations
(@interface implement (func 12) (func 11))
(@interface implement (func 14) (func 13))

sh
marine it artifacts/greeting.wasm
(@interface it_version "0.23.0")
;; Types
(@interface type (func
  (param $size: i32)
    (result i32)))   ;; 0
...
;; Exports
(@interface export "allocate" (func 0))
(@interface export "release_objects" (func 1))
...
;; Implementations
(@interface implement (func 12) (func 11))
(@interface implement (func 14) (func 13))

repl: run mrepl

Runs the Marine REPL:

sh
marine repl

set: set IT or SDK version

sh
marine help set
USAGE:
    marine set [SUBCOMMAND]
FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
SUBCOMMANDS:
    help       Prints this message or the help of the given subcommand(s)
    it         Sets given interface types to the provided Wasm file
    version    Sets given sdk version to the provided Wasm file

sh
marine help set
USAGE:
    marine set [SUBCOMMAND]
FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
SUBCOMMANDS:
    help       Prints this message or the help of the given subcommand(s)
    it         Sets given interface types to the provided Wasm file
    version    Sets given sdk version to the provided Wasm file

For example:

sh
marine set version -i artifacts/greeting.wasm -v 0.7.0
the version was successfully embedded

sh
marine set version -i artifacts/greeting.wasm -v 0.7.0
the version was successfully embedded

Lets check it worked:

sh
marine info artifacts/greeting.wasm
it version:  0.23.0
sdk version: 0.7.0
authors:     Fluence Labs
version:     0.1.0
