Elixir 1.18 deprecation warnings from transitive dependencies

[nshkrdotcom]

Summary

When compiling with Elixir 1.18, several transitive dependencies emit deprecation warnings.

Environment

• Elixir: 1.18
• OTP: 28

Affected Dependencies

1. toml v0.7.0 (via llm_db → req_llm)

15 warnings about deprecated single-quoted charlist syntax:

warning: using single-quoted strings to represent charlists is deprecated.
Use ~c"" if you indeed want a charlist or use "" instead.

Affected lines in lib/decoder.ex: 264, 371, 419, 474, 514, 518, 522, 538, 542, 682, 796, 916, 954, 969, 983

Upstream: bitwalker/toml-elixir#46

2. abacus v2.1.0 (via jido_action)

9 warnings about undefined/private function:

warning: Abacus.parse/1 is undefined or private
└─ lib/format.ex:36:14: Abacus.Format.format/1

This appears to be a bug in abacus where Abacus.Format calls Abacus.parse/1 which doesn't exist or is private.

Upstream: https://github.com/narrowtux/abacus

3. git_hooks v0.8.1 (direct dependency)

1 warning about deprecated function:

warning: GitHooks.Tasks.MFA.new/3 is deprecated. Use mfa without arity
└─ lib/git_hooks.ex:61:9: GitHooks.new_task/3

Current Status

All packages are at their latest versions on Hex. No fixes available upstream.

Suggested Actions

1. Monitor upstream repos for Elixir 1.18 compatibility updates
2. Consider pinning jido_action to remove abacus if not needed
3. Consider forking toml with mix format --migrate applied if upstream remains inactive
