Find and replace multi-lines using a match-case

Usage: matchpick [OPTIONS] [FILE]

Arguments:
  [FILE]  Read from file (otherwise from stdin)

Options:
  -m, --match <MATCH_AGAINST>            Match against (can be used multiple times)
  -s, --start-pattern <START_PATTERN>    Pattern to start matching and switch cases [default: ~>>>]
  -e, --end-pattern <END_PATTERN>        Pattern to end matching [default: ~<<<]
      --ignore-pattern <IGNORE_PATTERN>  Pattern to ignore other patterns
  -o, --output <OUTPUT>                  Output to file (otherwise to stdout)
      --print-start                      Print default starting pattern
      --print-end                        Print default ending pattern
  -h, --help                             Print help
  -V, --version                          Print version

As an example, the input:

start
~>>>
default output
~>>> eggs
foo, foo
~>>> spam
foo? bar!
foo... baz.
~<<<
end

Produces with default arguments:

start
default output
end

Produces with --match eggs:

start
foo, foo
end

Produces with --match spam:

start
foo? bar!
foo... baz.
end

Produces with --match something_else:

start
default output
end

You may specify multiple words to match with or against. This will result in the first full-word match will. For example:

~>>>
This will match against "gamma"
~>>> one alpha betagamma
This will match against "one", "alpha", "one two", "two one", "two beta alpha", "betagamma"
~>>> two beta
This will match against "two", "beta", "two beta", "beta two"
~<<<
