Bug Description

Thebin/dev --verbose option is documented in the help text but is not actually implemented in the OptionParser, causing an error when users try to use it.

Steps to Reproduce

cd spec/dummy./bin/dev --verbose

Expected Behavior

The command should run with verbose output for pack generation, showing the fullbundle exec rake react_on_rails:generate_packs output.

Actual Behavior

/lib/react_on_rails/dev/server_manager.rb:162:in `run_from_command_line': invalid option: --verbose (OptionParser::InvalidOption)

Root Cause Analysis

The issue was introduced when therun_from_command_line method was refactored in commitce30d89 (#1790). The verbose parameter support was added earlier in commit3878825, but when the OptionParser was created in the later commit, the--verbose/-v flag parsing was not included.

Current State

1. ✅ Help text documents--verbose, -v option (line 218 inlib/react_on_rails/dev/server_manager.rb)
2. ✅start() method acceptsverbose: parameter (line 11)
3. ✅ Verbose parameter is threaded through toPackGenerator.generate() (lines 419, 426)
4. ✅PackGenerator correctly implements verbose output behavior
5. ❌ OptionParser inrun_from_command_line() does NOT parse--verbose or-v (lines 147-162)
6. ❌ All calls tostart() hardcodeverbose: false (lines 170, 172, 178)

Fix Required

Inlib/react_on_rails/dev/server_manager.rb, add to the OptionParser (around line 157):

opts.on("-v","--verbose","Enable verbose output for pack generation")dooptions[:verbose]=trueend

Then update thestart() calls to use the option:

# Line 170start(:production_like,nil,verbose:options[:verbose],route:options[:route],rails_env:options[:rails_env])# Line 172start(:static,"Procfile.dev-static-assets",verbose:options[:verbose],route:options[:route])# Line 178start(:development,"Procfile.dev",verbose:options[:verbose],route:options[:route])

And initialize the options hash with the verbose key (line 145):

options={route:nil,rails_env:nil,verbose:false}

Impact

• Users cannot enable verbose pack generation output
• Documentation misleads users about available options
• Debugging pack generation issues is harder than intended
