Updating Thagore

The thagore update command lets you check for new releases, apply them in-place, and roll back if something goes wrong — all without leaving your terminal.

Check Your Current Version

thagore --version
# thagore 0.3.33-foundation (linux/x86_64)

`thagore update check`

Queries GitHub Releases and reports whether a newer version is available. Does not download or install anything.

thagore update check

Example output — up to date:

thagore 0.3.33-foundation is up to date.

Example output — update available:

Update available: 0.3.33-foundation → 0.3.34-foundation
Run `thagore update apply` to install.

`thagore update apply`

Downloads the latest release for your platform and replaces the current binary.

thagore update apply

By default this asks for confirmation before writing to disk:

Update available: 0.3.33-foundation → 0.3.34-foundation
Apply update? [Y/n]:

Skip the prompt

thagore update apply --yes

Dry run (preview only, no changes)

thagore update apply --dry-run

[dry-run] Would download: thagore-linux-x86_64.tar.gz (v0.3.34-foundation)
[dry-run] Would replace: /usr/local/bin/thagore
No files were changed.

`thagore update rollback`

Restores the previous version of the compiler that was saved before the last apply. Thagore keeps one backup automatically.

thagore update rollback

Prompts for confirmation before restoring:

Roll back from 0.3.34-foundation to 0.3.33-foundation? [Y/n]:

Skip the prompt

thagore update rollback --yes

Auto Update Notifications

By default, Thagore silently checks for updates in the background once every 24 hours and prints a one-line notice on your next compiler invocation:

Notice: thagore 0.3.34-foundation is available. Run `thagore update apply` to install.

To disable this behaviour, set the environment variable THAGORE_DISABLE_UPDATE_CHECK=1:

🐧 Linux / 🍎 macOS
🪟 Windows (PowerShell)

# Disable for current session
export THAGORE_DISABLE_UPDATE_CHECK=1

# Disable permanently (add to ~/.bashrc or ~/.zshrc)
echo 'export THAGORE_DISABLE_UPDATE_CHECK=1' >> ~/.bashrc

# Disable for current session
$env:THAGORE_DISABLE_UPDATE_CHECK = "1"

# Disable permanently (user scope)
[Environment]::SetEnvironmentVariable("THAGORE_DISABLE_UPDATE_CHECK", "1", "User")
