Ability to use response files and in-built parser (text => args) from spectre.console to provide consistent behavior

[rajasekarshanmugam]

Is your feature request related to a problem? Please describe. For some CLI, no of commands and the commands supported will be many. Using a typical command line is harder and has to be backed by other shell mechanisms. Would be good if a standard response file is supported. Response files typically are simple text files containing the commands, options/arguments. Response files come in different flavors too, single command/option per line or as a single line etc.

Describe the solution you'd like Response files are typically passed via command-line argument @responsefile and this could be the only argument when passed. Console programs tend to read the response file instead of the command line arguments and would parse/split as per needs instead of the default command line arguments (args[] via Main, or Environment.GetCommandLineArgs()).

Describe alternatives you've considered Currently no alternative solution. While it's easy to detect the presence of a response file argument parsing the text file into arguments is needed.

I'd Thumbs up this request, Nate McMasters has this in his CLI, but we have other reasons with continue with this one.

I thought I had read somewhere that Spectre.Console supported response files (to pass/intersperse command line arguments), but it looks from this that I must have misread?

Yeah, this feature request is still open. Happy to take a look at a pull request if someone wants to give it a go.
