The work is inspired by the Solc-select tool for managing and switching between versions of the Solidity compiler, which I actively use in my work. However, what has a significant disadvantage for me is the dependence on Python or the need to use Docker as an isolating environment.

Go-solc-select - is a simple program that installs the Solidity compiler and switches between them. This can be a useful tool for managing different versions of the Solidity compiler, checking available versions for a particular operating system. It is designed to be easy to install and use.

The tool is split into two CLI utilities:

• gsolc-select: manages installing and setting different solc compiler versions
• solc: wrapper around solc which picks the right version according to what was set via gsolc-select

The solc binaries are downloaded from https://binaries.soliditylang.org/ which contains official artifacts for many historial and modern solc versions for Linux and macOS.

The downloaded binaries are stored in ~/.gsolc-select/artifacts/.

Go-solc-select is designed for use on Unix/Linux/POSIX systems as a command line tool.

Go-solc-select requires go1.17 to install successfully. Run the command below to install the latest version.

To install gsolc-select:

go install -v github.com/fabelx/go-solc-select/cmd/gsolc-select@latest

To install solc wrapper:

go install -v github.com/fabelx/go-solc-select/cmd/solc@latest

gsolc-select --help

This will display help for the gsolc-select.

gsolc-select

  Allows users to installer and quickly switch between Solidity compiler versions

Usage:
  gsolc-select [command]

Examples:
  gsolc-select versions current - get current solc version
  gsolc-select install 0.8.1 - install a solc compiler
  gsolc-select use 0.8.1 - switch current version to 0.8.1
  gsolc-select uninstall 0.8.1 - remove solc compiler
  gsolc-select uninstall 0.8.1 0.8.17 -v - remove solc compilers verbose
  gsolc-select versions - get installed solc compiler versions
  gsolc-select versions installable - get installable solc compiler versions for current platform (OS)


Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  install     Install available solc versions
  uninstall   Remove installed solc versions
  use         Change the version of global solc compiler
  versions    Installed solc versions

Flags:
  -h, --help      help for gsolc-select
  -j, --json      indicate if you want to use json format for logging details
  -s, --verbose   indicate if you want for log details
  -v, --version   version for gsolc-select
