Script to inject Std.int on Float should be Int

float_fix.rb

#!/usr/bin/ruby
#
# Usage: haxe Test.hx -main Test -cpp test 2>&1 | float_fix.rb
#
# Modifies files which appear on error lines as:
#
#  Test.hx:15: characters 12-18 : Float should be Int
#
# Changes Test.hx line 15 from: needInt( 4.5 - 3 ) ;
#                           to: needInt( Std.int(4.5 - 3) ) ;
#
# (does not work on multi-line errors, e.g. Test.hx:15: lines 15-16 : Float should be Int)
