Compact developer tools 0.4.0 release notes​

Today we are releasing the Compact developer tools (devtools) 0.4.0. This release improves the compact fixup command with a simplified interface and a new check mode for CI workflows.

If you have an existing devtools installation, you can update it with the command compact self update.

If you do not have an existing devtools installation, you can install version 0.4.0 using the shell command shown on the release page.

Breaking Changes​

The compact fixup command now operates in-place by default​

Previously, compact fixup would output fixed code to stdout by default, and you needed to pass --in-place or -i to modify files directly. In version 0.4.0, the command modifies files in-place by default, and the --in-place flag has been removed.

If you have scripts that relied on the stdout behavior, you should update them to use the new --check flag, which outputs diffs without modifying files.

New Features​

Check mode for compact fixup​

The new --check (or -c) flag allows you to verify whether files need fixup without actually modifying them. This is useful for CI pipelines or pre-commit hooks where you want to fail the build if contracts are not properly fixed up.

compact fixup --check .

When changes are needed, the command will:

  • Print a diff showing what would be changed
  • Exit with a non-zero status code

When no changes are needed, the command exits successfully with no output.

Simplified directory processing​

You can now run compact fixup on directories without any special flags:

compact fixup .

This will process all .compact files in the directory (excluding those matched by .gitignore), fixing them up in place.

Version information from the underlying tools​

The --version (-V) and new --language-version flags for both compact fixup and compact format now report version information from the underlying toolchain tools (fixup-compact and format-compact) rather than the devtools version.

This makes it easier to verify which language version your tools support:

compact fixup --language-version
compact format --language-version

Bug Fixes​

Improved error message for missing formatter​

When the formatter is not available, the error message now provides clearer guidance:

Error: formatter not available - please install a compiler version that includes format-compact
