This results in very simple -and concise specification of your application options. For example: - - type Options struct { - Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"` - } - -This specifies one option with a short name -v and a long name --verbose. -When either -v or --verbose is found on the command line, a 'true' value -will be appended to the Verbose field. e.g. when specifying -vvv, the -resulting value of Verbose will be {[true, true, true]}. - -Slice options work exactly the same as primitive type options, except that -whenever the option is encountered, a value is appended to the slice. - -Map options from string to primitive type are also supported. On the command -line, you specify the value for such an option as key:value. For example - - type Options struct { - AuthorInfo string[string] `short:"a"` - } - -Then, the AuthorInfo map can be filled with something like --a name:Jesse -a "surname:van den Kieboom". - -Finally, for full control over the conversion between command line argument -values and options, user defined types can choose to implement the Marshaler -and Unmarshaler interfaces. - - -Available field tags - -The following is a list of tags for struct fields supported by go-flags: - - short: the short name of the option (single character) - long: the long name of the option - required: whether an option is required to appear on the command - line. If a required option is not present, the parser will - return ErrRequired (optional) - description: the description of the option (optional) - long-description: the long description of the option. Currently only - displayed in generated man pages (optional) - no-flag: if non-empty this field is ignored as an option (optional) - - optional: whether an argument of the option is optional. When an - argument is optional it can only be specified using - --option=argument (optional) - optional-value: the value of an optional option when the option occurs - without an argument. This tag can be specified multiple - times in the case of maps or slices (optional) - default: the default value of an option. This tag can be specified - multiple times in the case of slices or maps (optional) - default-mask: when specified, this value will be displayed in the help - instead of the actual default value. This is useful - mostly for hiding otherwise sensitive information from - showing up in the help. If default-mask takes the special - value "-", then no default value will be shown at all - (optional) - env: the default value of the option is overridden from the - specified environment variable, if one has been defined. - (optional) - env-delim: the 'env' default value from environment is split into - multiple values with the given delimiter string, use with - slices and maps (optional) - value-name: the name of the argument value (to be shown in the help) - (optional) - choice: limits the values for an option to a set of values. - This tag can be specified mltiple times (optional) - hidden: the option is not visible in the help or man page. - - base: a base (radix) used to convert strings to integer values, the - default base is 10 (i.e. decimal) (optional) - - ini-name: the explicit ini option name (optional) - no-ini: if non-empty this field is ignored as an ini option - (optional) - - group: when specified on a struct field, makes the struct - field a separate group with the given name (optional) - namespace: when specified on a group struct field, the namespace - gets prepended to every option's long name and - subgroup's namespace of this group, separated by - the parser's namespace delimiter (optional) - command: when specified on a struct field, makes the struct - field a (sub)command with the given name (optional) - subcommands-optional: when specified on a command struct field, makes - any subcommands of that command optional (optional) - alias: when specified on a command struct field, adds the - specified name as an alias for the command. Can be - be specified multiple times to add more than one - alias (optional) - positional-args: when specified on a field with a struct type, - uses the fields of that struct to parse remaining - positional command line arguments into (in order - of the fields). If a field has a slice type, - then all remaining arguments will be added to it. - Positional arguments are optional by default, - unless the "required" tag is specified together - with the "positional-args" tag. The "required" tag - can also be set on the individual rest argument - fields, to require only the first N positional - arguments. If the "required" tag is set on the - rest arguments slice, then its value determines - the minimum amount of rest arguments that needs to - be provided (e.g. `required:"2"`) (optional) - positional-arg-name: used on a field in a positional argument struct; name - of the positional argument placeholder to be shown in - the help (optional) - -Either the `short:` tag or the `long:` must be specified to make the field eligible as an -option. - - -Option groups - -Option groups are a simple way to semantically separate your options. All -options in a particular group are shown together in the help under the name -of the group. Namespaces can be used to specify option long names more -precisely and emphasize the options affiliation to their group. - -There are currently three ways to specify option groups. - - 1. Use NewNamedParser specifying the various option groups. - 2. Use AddGroup to add a group to an existing parser. - 3. Add a struct field to the top-level options annotated with the - group:"group-name" tag. - - - -Commands - -The flags package also has basic support for commands. Commands are often -used in monolithic applications that support various commands or actions. -Take git for example, all of the add, commit, checkout, etc. are called -commands. Using commands you can easily separate multiple functions of your -application. - -There are currently two ways to specify a command. - - 1. Use AddCommand on an existing parser. - 2. Add a struct field to your options struct annotated with the - command:"command-name" tag. - -The most common, idiomatic way to implement commands is to define a global -parser instance and implement each command in a separate file. These -command files should define a go init function which calls AddCommand on -the global parser. - -When parsing ends and there is an active command and that command implements -the Commander interface, then its Execute method will be run with the -remaining command line arguments. - -Command structs can have options which become valid to parse after the -command has been specified on the command line, in addition to the options -of all the parent commands. I.e. considering a -v flag on the parser and an -add command, the following are equivalent: - - ./app -v add - ./app add -v - -However, if the -v flag is defined on the add command, then the first of -the two examples above would fail since the -v flag is not defined before -the add command. - - -Completion - -go-flags has builtin support to provide bash completion of flags, commands -and argument values. To use completion, the binary which uses go-flags -can be invoked in a special environment to list completion of the current -command line argument. It should be noted that this `executes` your application, -and it is up to the user to make sure there are no negative side effects (for -example from init functions). - -Setting the environment variable `GO_FLAGS_COMPLETION=1` enables completion -by replacing the argument parsing routine with the completion routine which -outputs completions for the passed arguments. The basic invocation to -complete a set of arguments is therefore: - - GO_FLAGS_COMPLETION=1 ./completion-example arg1 arg2 arg3 - -where `completion-example` is the binary, `arg1` and `arg2` are -the current arguments, and `arg3` (the last argument) is the argument -to be completed. If the GO_FLAGS_COMPLETION is set to "verbose", then -descriptions of possible completion items will also be shown, if there -are more than 1 completion items. - -To use this with bash completion, a simple file can be written which -calls the binary which supports go-flags completion: - - _completion_example() { - # All arguments except the first one - args=("${COMP_WORDS[@]:1:$COMP_CWORD}") - - # Only split on newlines - local IFS=$'\n' - - # Call completion (note that the first element of COMP_WORDS is - # the executable itself) - COMPREPLY=($(GO_FLAGS_COMPLETION=1 ${COMP_WORDS[0]} "${args[@]}")) - return 0 - } - - complete -F _completion_example completion-example - -Completion requires the parser option PassDoubleDash and is therefore enforced if the environment variable GO_FLAGS_COMPLETION is set. - -Customized completion for argument values is supported by implementing -the flags.Completer interface for the argument value type. An example -of a type which does so is the flags.Filename type, an alias of string -allowing simple filename completion. A slice or array argument value -whose element type implements flags.Completer will also be completed. -*/ -package flags diff --git a/vendor/src/github.com/jessevdk/go-flags/group.go b/vendor/src/github.com/jessevdk/go-flags/group.go deleted file mode 100644 index b1ef6ed62..000000000 --- a/vendor/src/github.com/jessevdk/go-flags/group.go +++ /dev/null @@ -1,385 +0,0 @@ -// Copyright 2012 Jesse van den Kieboom.
