Bug: lint:scripts exits with code 8 instead of 0 due to missing_count.size typo

[nickpellant]

Description

The i18n lint:scripts command always exits with code 8 on 64-bit systems when there are 0 missing translations, instead of exiting with code 0.

The bug is in lib/i18n-js/cli/lint_scripts_command.rb at line 140:

exit(missing_count.size)

This calls Integer#size on missing_count, which returns the number of bytes needed to store the integer value (8 on 64-bit systems), rather than the integer itself.

How to reproduce

1. Set up a project with i18n-js configured with lint_scripts patterns
2. Ensure all translations are present (0 missing)
3. Run bundle exec i18n lint:scripts
4. Observe the exit code: echo $? returns 8

$ bundle exec i18n lint:scripts
=> Config file: "./config/i18n.yml"
=> Require file: "./config/environment.rb"
=> Node: "/usr/local/bin/node"
=> Available locales: [:en]
=> Patterns: ["app/frontend/**/*.ts", "app/frontend/**/*.tsx"]
=> 172 translations, 0 missing, 0 ignored

$ echo $?
8

What do you expect

When there are 0 missing translations, the command should exit with code 0 (success).

What happened instead

The command exits with code 8 because 0.size returns 8 on 64-bit systems (the number of bytes needed to store an Integer).

Suggested fix

Change line 140 from:

exit(missing_count.size)

To:

exit(missing_count)

Software:

• Gem version: 4.2.4
• Ruby version: 3.4.7 (also reproducible on other versions)

Full backtrace

N/A - no exception is raised, the bug is in the exit code logic
