Kotlin Native library for create sub-process and redirect their I/O.

Rust is an excellent language that takes into account both performance and engineering.

In version 1.x, we use the following API to provide the function of creating child processes

• fork of [POSIX api]
• CreateChildProcess of [win32 api]
• java.lang.ProcessBuilder of JVM

In version 2.x, we use the Rust standard library to provide the function of creating child processes.

• std::process::Command of Rust
• java.lang.ProcessBuilder of JVM

It will bring

• More unified API
• Easier to use API
• Performance is still excellent
• Easier to maintain
• Code structure is clearer

• x86_64-apple-darwin
• aarch64-apple-darwin
• x86_64-unknown-linux-gnu
• aarch64-unknown-linux-gnu
• x86_64-pc-windows-gnu (mingw-w64)
• jvm

• Rust Standard Library 1.83.0
• Kotlin Multiplatform 2.1.0

Dependency:

• required kotlinx-coroutines

• rust toolchain - 1.83.0 (https://rustup.rs)
  • just (install with cargo install just)
• cross-compile toolchain
  • x86_64-apple-darwin
  • aarch64-apple-darwin
  • x86_64-unknown-linux-gnu
  • aarch64-unknown-linux-gnu
  • x86_64-pc-windows-gnu (mingw-w64)
• docker (optional)

Recommend build all platforms in macOS.

Kotlin Multiplatform gets the most complete support on macOS.

If you are using macOS, you can install the cross-compile toolchain with

just prepare

Otherwise, you need to install the cross-compile toolchain yourself.

git clone https://github.com/kgit2/kommand.git

cd kommand-core
just all

./gradlew build

Only linux support cross-platform test.

• install docker

Install Docker Engine

• test it

# for x86_64
just linuxX64Test
# for aarch64
just linuxArm64Test
