Hi,
I am relatively new to clojure and while using the contrib.command-
line, I found there is a place for a small improvement, at least for
my usecase :-)
I use the with-command-line macro and then check eg. that the
remaining parameters, that are not caught amount to the right number
(eg. I want to have a commandline, where there are options and at most
two additional arguments). In case the check fails, it would be
beautiful to print the help message that gets printed, when -h or --
help is provided. Currently I cannot call the "print-help" function
because I do not have access to the necessary parameters.
If the with-command-line macro would be slightly changed to add a
binding to a "print-usage" function:
like
(let [~(symbol "print-usage") #(print-help ~desc cmdmap#) ]
then it be possible to do something like this:
(with-command-line ["-s" "1" "2"] "Usage: testfile [Options]
<configuration file> <outputfile>"
[[synonyms? s? "Use Synonyms"][normalizer? n? "Use Normalizer"]
files]
(if (= 2 (count files))
(println (files 0))
;;else
(print-usage)))
Is that a good idea?
