Re: text processing function
Hey Glen, it appears that zipmap most directly corresponds to your initial
question.
The only complicating aspect is your desire for nils, which (concat result
(repeat nil)) addresses.
(zipmap [:fullname :lastname :firstname :middlename] (concat result
(repeat nil)))
If it weren't for the need for nils,
(zipmap [:fullname :lastname :firstname :middlename] result)
is simple and noise-free. Note that the nils are unnecessary if later
using map destructuring:
(defn use-names [{:keys [fullname lastname firstname middlename]}]
(println fullname lastname firstname middlename))
For example, nils are generated at call time for you by the map
destructuring:
(use-names (zipmap [:fullname :lastname :firstname :middlename] ["John
Lou Doe" "Doe" "John"]))
;=> John Lou Doe Doe John nil

Re: text processing function
Just golfing for fun:
(apply hash-map (interleave [:fullname :lastname :firstname :middlename]
(concat ["John Lou Doe" "Doe" "John"] (repeat nil
;=> {:firstname "John", :lastname "Doe", :middlename nil, :fullname "John
Lou Doe"}

Re: text processing function
These are both very good and usable answers. Thank you both!

Re: text processing function
What about:
{:fullname (get result 0), :lastname (get result 1), :firstname (get result
2), :middlename (get result 3)}
If the "get" function can't find a result, it returns nil.

Re: text processing function
Array destructuring appears to provide what you want with respect to nils
(note the extra set of square braces within the argument list):
(defn make-map
[[fullname lastname firstname middlename]]
{:fullname fullname
:lastname lastname
:firstname firstname
:middlename middlename})
(make-map ["John Lou Doe" "Doe" "John" "Lou"])
;=> {:fullname "John Lou Doe", :lastname "Doe", :firstname "John",
:middlename "Lou"}
(make-map ["John Lou Doe" "Doe" "John"])
;=> {:fullname "John Lou Doe", :lastname "Doe", :firstname "John",
:middlename nil}
(make-map ["John Lou Doe" "Doe"])
;=> {:fullname "John Lou Doe", :lastname "Doe", :firstname nil, :middlename
nil}
(make-map ["John Lou Doe"])
;=> {:fullname "John Lou Doe", :lastname nil, :firstname nil, :middlename
nil}
(make-map [])
;=> {:fullname nil, :lastname nil, :firstname nil, :middlename nil}
(make-map nil)
;=> {:fullname nil, :lastname nil, :firstname nil, :middlename nil}

text processing function
I am doing some text processing using clojure and attempting to extract a
person's name by regex and then assign it to a map. The result I get takes
one of several forms:
nil (if i can't find the name)
[fullname]
[fullname lastname]
[fullname lastname firstname]
[fullname lastname firstname middlename]
now, basically want to assign these entries to a map like so {:fullname
"some name", :lastname "some name", etc...}
if there is no entry than I would like to assign it as nil, e.g. {:fullname
nil, lastname nil, etc...}
I want to code this in the most proper way. I am thinking I need to define
a function that works differently based on how long the vector is? How do
I turn the contents of the vector into function arguments?
Thanks!
