Support multiple files from the CLI (support dir globs)

Inizia in lib/dead_end/cli.rb intorno alle righe 43-55, dove la CLI gestisce attualmente i propri input, e segui come viene selezionato il primo percorso. Controlla le specifiche esistenti della CLI e di integrazione relative al comportamento degli argomenti. Il lavoro è completato quando un comando come dead_end **/*.rb elabora ogni file espanso invece di elaborare solo il primo.

Problem

To run this against multiple files developers want to run:

$ dead_end **/*.rb

This doesn't work today due to terminal globbing, which we don't yet support. What's happening when that command is run is that info isn't coming to dead_end. Your shell is expanding the input to be all files:

$ echo **/*.rb
lib/dead_end.rb lib/dead_end/around_block_scan.rb lib/dead_end/auto.rb lib/dead_end/block_expand.rb lib/dead_end/capture_code_context.rb lib/dead_end/clean_document.rb lib/dead_end/cli.rb lib/dead_end/code_block.rb lib/dead_end/code_frontier.rb lib/dead_end/code_line.rb lib/dead_end/code_search.rb lib/dead_end/display_code_with_line_numbers.rb lib/dead_end/display_invalid_blocks.rb lib/dead_end/explain_syntax.rb lib/dead_end/insertion_sort.rb lib/dead_end/left_right_lex_count.rb lib/dead_end/lex_all.rb lib/dead_end/lex_value.rb lib/dead_end/parse_blocks_from_indent_line.rb lib/dead_end/ripper_errors.rb lib/dead_end/version.rb spec/integration/dead_end_spec.rb spec/integration/exe_cli_spec.rb spec/integration/ruby_command_line_spec.rb spec/spec_helper.rb spec/unit/around_block_scan_spec.rb spec/unit/block_expand_spec.rb spec/unit/capture_code_context_spec.rb spec/unit/clean_document_spec.rb spec/unit/cli_spec.rb spec/unit/code_block_spec.rb spec/unit/code_frontier_spec.rb spec/unit/code_line_spec.rb spec/unit/code_search_spec.rb spec/unit/display_invalid_blocks_spec.rb spec/unit/explain_syntax_spec.rb spec/unit/insertion_sort_spec.rb spec/unit/lex_all_spec.rb

So what's really happening when you run that dead_end **/*.rb command (I think) is that we're only looking at the first file in the list. i.e. calling this:

$ dead_end **/*.rb

Is functionally the same as calling:

$ dead_end lib/dead_end.rb # based on the file output from above

That's the problem.

Solution

The fix would be pretty easy, which would be to look at all inputs rather than just the first one. Essentially change this in the CLI to loop over all args, https://github.com/zombocom/dead_end/blob/e8eb54c651bfa196fc933f76def5d811bb5d57dc/lib/dead_end/cli.rb#L43-L55
