Installation

Install and switch DCR versions (stable / dev / night, pin 0.8.2, optional build from source).

Linux / macOS / BSD / Windows (bash)​

curl -fsSL https://sh.dcr-tool.ru | sh -s -- self-install
export PATH="$HOME/.dcr/bin:$PATH"
dcrup install stable

Non-interactive install of DCR in one shot:

curl -fsSL https://sh.dcr-tool.ru | sh -s -- install stable
export PATH="$HOME/.dcr/bin:$PATH"

Windows (PowerShell)​

irm https://ps1.dcr-tool.ru | iex
# or download then run:
# irm https://ps1.dcr-tool.ru -OutFile dcrup.ps1
# powershell -File .\dcrup.ps1 self-install
# $env:Path += ";$env:USERPROFILE\.dcr\bin"
dcrup install stable

Optional cmd bootstrap (if you prefer curl of the cmd shim):

curl -fsSL -o dcrup.cmd https://cmd.dcr-tool.ru

After self-install, the command is dcrup (no .sh / .ps1): shims live in ~/.dcr/bin (Unix) or %USERPROFILE%\.dcr\bin (Windows dcrup.cmd).
