Building a Module

TODO

Development

Prerequisites

Verify you have Go 1.17+ installed

go version

If Go is not installed, download and install Go 1.17+ (brew installation is not recommended because of CGO linker warnings)

Clone the project from github

git clone https://github.com/apexlang/apex.git
cd cli
go install ./cmd/...

Compiling on Windows

In order to build a project using v8go on Windows, Go requires a gcc compiler to be installed.

To set this up:

1. Install MSYS2 (https://www.msys2.org/)
2. Add the Mingw-w64 bin to your PATH environment variable (C:\msys64\mingw64\bin by default)
3. Open MSYS2 MSYS and execute pacman -S mingw-w64-x86_64-toolchain

V8 requires 64-bit on Windows, therefore it will not work on 32-bit systems.

Confirm apex runs (The Go installation should add ~/go/bin in your PATH)

apex --help

Output:

Usage: apex <command>

Flags:
  -h, --help    Show context-sensitive help.

Commands:
  install <location> [<release>]
    Install a module.

  generate [<config>]
    Generate code from a configuration file.

  watch [<configs> ...]
    Watch configuration files for changes and trigger code generation.

  new <template> <dir> [<variables> ...]
    Creates a new project from a template.

  init <template> [<variables> ...]
    Initializes an existing project directory from a template.

  upgrade
    Upgrades to the latest base modules dependencies.

  version

Run "apex <command> --help" for more information on a command.

Built With

• esbuild - An extremely fast JavaScript bundler written in Go that is used to compile the code generation TypeScript modules into JavaScript that can run natively in V8.
• v8go and V8 - Execute JavaScript from Go
• kong - A very simple and easy to use command-line parser for Go
• The Go 1.16 embed package - Finally embedding files is built into the Go toolchain!
