Command line parser rust lib crate
Command line parser is able to parse process arguments. Arguments could be of two types, single character argument (i.g -c) or long text argument (i.g. --config-file)
Process argument could be of the following type:
- Boolean: classic is -h to show process help.
- Integer: an integer value for example verbosity level --verbose 5.
- Floating point: a floating point numer --ratio=123.25 .
- String: a text argument, classic configuration file path --config-file app.properties.
Argument can be passed in two ways: --config-file=config/app.properties or --config-file config/app.propertiesthe same example is valid for single character options -c=config/app.properties or -c config/app.properties.
Single character option can be pass grouped together (i.g -xvz). Be careful if a single character argument needs an argument you have to pass it or adding = and the value (i.g. -xvzf=file_to_compress.tar.gz) or as next process argument (i.g -xvzf file_to_compress.tar.gz). NOTE: No more than a single character option with a mandatory argument can be grouped.
