Install and check tidas

Use the prebuilt executables from the official v0.2.0 release. The installers download the fixed platform archive and its .sha256, then install only after verification. You may download and inspect the script before running it.

macOS and Linux

curl --proto '=https' --tlsv1.2 -fsSLO https://github.com/tiangong-lca/tidas-tools/releases/download/v0.2.0/install.sh
sh install.sh --version 0.2.0 --prefix "$HOME/.local"
"$HOME/.local/bin/tidas" --version

Add the installation directory to PATH in the current terminal to run tidas directly:

export PATH="$HOME/.local/bin:$PATH"
tidas --version

This export affects only the current terminal. For persistent use, add the same PATH setting to your shell startup configuration. Otherwise, invoke "$HOME/.local/bin/tidas" by its full path.

Windows PowerShell

Invoke-WebRequest https://github.com/tiangong-lca/tidas-tools/releases/download/v0.2.0/install.ps1 -OutFile install.ps1
.\install.ps1 -Version 0.2.0
& "$env:LOCALAPPDATA\Programs\tidas\bin\tidas.exe" --version

After installation, add the command directory in your current PowerShell:

$env:Path = "$env:LOCALAPPDATA\Programs\tidas\bin;$env:Path"
tidas --version

For persistent use, add the same bin directory to your Windows user Path and open a new PowerShell. If organizational policy blocks scripts, follow your organization’s security process rather than disabling that policy to install.

Choose the correct platform

Windows ARM64 has no prebuilt support in this release. Do not mix ARM64 and x86_64 archives. The release also supplies SHA-256 checksums, SPDX SBOMs, a Homebrew formula, and Winget manifests; the last two do not imply availability in external package repositories.

Confirm installation

tidas --version
tidas version --format json
tidas --help

tidas --version should print tidas 0.2.0. tidas version --format json returns machine-readable version details; tidas --help lists commands. If the command is missing, try its full installation path to distinguish a PATH problem.

Next: Validate and convert your first package.
