coerceclj/s
(coerce s f)Coerce string s using f. Does not coerce when s is not a string.
f may be a keyword (:boolean, :int, :double, :symbol,
:keyword) or a function. When f return nil, this is
interpreted as a parse failure and throws.
Coerce string `s` using `f`. Does not coerce when `s` is not a string. `f` may be a keyword (`:boolean`, `:int`, `:double`, `:symbol`, `:keyword`) or a function. When `f` return `nil`, this is interpreted as a parse failure and throws.
coerce-valsclj/s
(coerce-vals m mapping)Coerce vals of map m using mapping, a map of keys to functions.
Uses coerce to coerce values.
Coerce vals of map `m` using `mapping`, a map of keys to functions. Uses `coerce` to coerce values.
parse-argsclj/s
(parse-args args)(parse-args args opts)Parse the command line arguments args, a seq of strings.
Expected format: ["cmd_1" ... "cmd_n" ":k_1" "v_1" .. ":k_n" "v_n"].
Instead of a leading : either -- or - may be used as well.
Return value: a map of :cmds and :opts
Supported options:
:coerce: a map of keys to coercion functions that will be applied to parsed:opts. Seecoerce-vals.:aliases: a map of short names to long names.
Examples:
(parse-args ["foo" ":bar" "1])
;; => {:cmds ["foo"] :opts {:bar "1"}}
(parse-args [":b" "1] {:aliases {:b :bar} :coerce {:bar parse-long}})
;; => {:cmds [] :opts {:bar 1}}
Parse the command line arguments `args`, a seq of strings.
Expected format: `["cmd_1" ... "cmd_n" ":k_1" "v_1" .. ":k_n" "v_n"]`.
Instead of a leading `:` either `--` or `-` may be used as well.
Return value: a map of `:cmds` and `:opts`
Supported options:
- `:coerce`: a map of keys to coercion functions that will be applied to parsed `:opts`. See `coerce-vals`.
- `:aliases`: a map of short names to long names.
Examples:
``` clojure
(parse-args ["foo" ":bar" "1])
;; => {:cmds ["foo"] :opts {:bar "1"}}
(parse-args [":b" "1] {:aliases {:b :bar} :coerce {:bar parse-long}})
;; => {:cmds [] :opts {:bar 1}}
