format -package:fmt

This returns whether the data was returned in a binary or textual format. Analogous to libpq's PQfformat.

Creates a string from a matrix given a separator and a function to show each entry. Using this function the user can easily define any desired display function:

import Text.Printf(printf)

disp = putStr . format "  " (printf "%.2f")

Run the formatter and return a lazy Text value.

Format a variable number of arguments with Python-style format string

>>> format "{:s}, {:d}, {:.4f}" "hello" 123 pi
"hello, 123, 3.1416"

>>> format "{1:s}, {0:d}, {2:.4f}" 123 "hello" pi
"hello, 123, 3.1416"

>>> format "{:s} {:d} {pi:.4f}" "hello" 123 ("pi" := pi)
"hello, 123, 3.1416"
