I am reading a file which is either separated by a "tab space" or "semicolon(;)" or "comma(,)" below code separates only tab space but i want all 3 to be checked. like if a file is comma separated it should work for that also . Please help!
#!/usr/bin/ruby
require 'csv'
test = CSV.read('test.csv', headers:true, :col_sep => "\t")
x = test.headers
puts x
It looks like :col_sep
cannot be a Regexp, which could have solved your problem.
One possible solution would be to analyze the head of your CSV file and count the occurences of possible separators :
require 'csv'
possible_separators = ["\t", ';', ',']
lines_to_analyze = 1
File.open('test.csv') do |csv|
head = csv.first(lines_to_analyze).join
@col_sep = possible_separators.max_by { |sep| head.count(sep) }
end
@col_sep
#=> ";"
You can then use :
test = CSV.read('test.csv', headers:true, :col_sep => @col_sep)
x = test.headers
puts x
# a
# b
# c
The values in x
won't contain any separator.
