v1.1.0 (Nov 2, 2023)

In this release:

• #77: --safety-check flag for checking that the output of smlfmt is correct, i.e., that the result is valid SML that exactly matches the source except for whitespace.
  • Note: originally called --check but renamed to --safety-check in #92.
• #84, #86: allow passing input and output through stdin and stdout.
  • For example: echo "val x = 5 val y = 6" | ./smlfmt or cat test.sml | ./smlfmt > output.sml
• #87: --read-only flag, useful for checking for syntax errors
• #93: make install formula
• #92: --check flag, to check if a file has already been formatted. Useful for CI.
• Some bugfixes and other small improvements, e.g., 656885b 4d1952a

Also note that https://github.com/diku-dk/smlfmt.el offers Emacs integration for smlfmt.
