how to paritally flatten a list in clojure? -


let's have data structure so:

[[1 2 3] [4 5 6] [[7 8 9] [10 11 12]]]

and want end is:

[[1 2 3] [4 5 6] [7 8 9] [10 11 12]]

is there function automatically?

basically i'm converting/transforming sql result set csv, , there rows transform 2 rows in csv. map function in normal case returns vector, returns vector of vectors. clojure.data.csv needs list of vectors only, need flatten out rows got pivoted.

mapcat useful mapping each element can expand 0 or more output elements, this:

(mapcat #(if (vector? (first %)) % [%]) data)

though i'm not sure if (vector? (first %)) sufficient test data.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
