This is a new fully working parser for the arg options. The parser is written generically so it can be used in all diffutils tools. The first implementation is done with sdiff. I already have a version for cmp as well. I checked and discarded clap as tool, as the requirements are very individual and would require extensive tweaking of the clap functionality. Features: - Allows options to be abbreviated, e.g. --wi instead of --width - Allows input like in GNU utils, e.g. the following are all identical - diff --ignore-case --minimal --width=50 file_a file_b - diff --ignore-case --minimal --width 50 file_a file_b - diff -i -d -w 50 file_a file_b - diff -id -w50 file_a file_b - diff -idw50 file_a file_b - A number parser is available, which parses option arguments with optional byte units, e.g. =1024 or =1024KiB - Default handling for --version and --help - Returns the params or an Error Enum, which makes it library friendly. - Contains error handling for the typical parsing errors: -- missing and extra operands -- invalid, ambiguous or conflicting options -- missing or not allowed option arguments - Provides error text functions, e.g. add executable and 'Try --help' to message.

Can you rebase the relevant commit (bfd8ebc) on top of main, i.e. without all the changes for your sdiff parser? |

Yes, that was indeed accidentally. Will fix it. Closing this PR. |
