Self Update

dcr --update

Automatic update to the latest version. Downloads a binary (not an archive) from GitHub Releases and replaces the current executable.

dcr --update

How it works

1. DCR detects the current platform and architecture
2. Fetches the latest release from api.github.com/repos/dexoron/dcr/releases/latest
3. Compares versions
4. Downloads the matching asset (direct binary URL, not archive)
5. Replaces the current executable via self_replace

Asset naming

Pattern: dcr-<triple> or dcr-<triple>.exe

Platform	Asset name
Linux x86_64	dcr-x86_64-unknown-linux-gnu
macOS x86_64	dcr-x86_64-apple-darwin
macOS ARM64	dcr-aarch64-apple-darwin
Windows x86_64	dcr-x86_64-pc-windows-msvc.exe

AUR

If DCR was installed via AUR, --update shows a warning:

Update via package manager: yay/paru -Syu {package_name} or sudo pacman -Syu {package_name}

Errors

• Cannot detect platform — error
• Cannot fetch release — error with URL
• No write permission — error (use sudo or manual install)
