Applies function f to the keys of the map m.

Applies function f to the values of the map m.

Completes the main path by padding a mpd- in case it is missing.

(u/compl-main-path "aaa")
;; "mpd-aaa"
(u/compl-main-path "mpd-aaa")
;; "mpd-aaa"

Replaces all of the @-signs (if followed by letters 1) by a %-sign because :%kw is a valid keyword but :@kw not (or at least problematic).

1) There are devices annotating channeles by (@101:105). This should remain as it is.

Ensures i to be integer. Returns 0 as default.

(u/ensure-int 100)
;; 100
(u/ensure-int "w")
;; 0
(u/ensure-int "00")
;; 0
(u/ensure-int "10")
;; 10
(u/ensure-int true)
;; 0

Extracts the main path. Should work on mpd-aaa-bbb as well as on aaa-bbb.

(u/extr-main-path "aa")
;; "aa"
(u/extr-main-path "aa-bbb")
;; "aa-bbb"
(u/extr-main-path "aa-bbb-lll")
;; "aa-bbb-lll"

Transforms a json object to a map.

Left pad the given number if it is not a string. Default is (cfg/key-pad-length (cfg/config)).

Example:

 (u/lp 2)
;; "002"
(u/lp "02")
;; "002"
(u/lp 2)
;; "002"
(u/lp true)
;; "000"
(u/lp "003")
;; "003"
(u/lp "000003")
;; "003"

Transforms a hash-map to a json string

Extracts next command.

#TODO: Enable kind of programming like provided in ssmp:

• load;run;stop –> [load, run, stop]
• load;2:run,stop –> [load, run, stop, run, stop]

Checks if the padding of i is ok. "*" serves pattern matching.

Short a string s to n or 45 chars. Returns nil is s is not a string.
