Logic for parsing the Miller command line.
src/cliis the flag-parsing logic for supporting Miller's command-line interface. When you type something likemlr --icsv --ojson put '$sum = $a + $b' then filter '$sum > 1000' myfile.csv, it's the CLI parser which makes it possible for Miller to construct a CSV record-reader, a transformer chain ofputthenfilter, and a JSON record-writer.src/cliutilcontains datatypes for the CLI-parser, which was split out to avoid a Go package-import cycle.- I don't use the Go
flagpackage. Theflagpackage is quite fine; Miller's command-line processing is multi-purpose between serving CLI needs per se as well as for manpage/docfile generation, and I found it simplest to roll my own command-line handling here. More importantly, some Miller verbs such assorttake flags more than once --mlr sort -f field1 -n field2 -f field3-- which is not supported by theflagpackage.
