ruby - How do I use a regular expression to match a number as an integer? -


when match number using regular expression string:

?> 'testingsubject2981'.match /\d+$/ => #<matchdata "2981">

is somehow possible number integer without to_is?

the issue regular expressions work on strings, not on other data types.

a regex has patterns match numbers, still find characters represent number, not binary values we'd use math. once engine returns matches, they're still characters, have use to_i convert them binary representations.

mmm-kay?

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
