screenify
(size_t nin, const string_arr_t &in_cols, std::vector<std::string> &out_cols, size_t max_size = 80)¶ Reformat the columns for output of width
size
.Given a string array
in_cols
of sizenin
, screenify() reformats the array into columns creating a new string arrayout_cols
.For example, for an array of 10 strings
screenify() will create an array of 3 new strings:test1 test_of_string2 test_of_string3 test_of_string4 test5 test_of_string6 test_of_string77 test_of_string8 test_of_string9 test_of_string10
test1 test_of_string4 test_of_string77 test_of_string10 test_of_string2 test5 test_of_string8 test_of_string3 test_of_string6 test_of_string9
If the value of
max_size
is less than the length of the longest input string (plus one for a space character), then the output strings may have a larger length thanmax_size
.
