i don't know how set content type can format email html example. though wish able define bold text email client does: bold text. know content-type need specify in order achieve , how implement mail?

just note, code above works fine sending plain text emails.

from documentation

writing , sending multipart/alternative (html , text) email

mail makes basic assumptions , makes doing common thing simple possible.... (asking lot mail library)

mail = mail.deliver        'nicolas@test.lindsaar.net.au'      'mikel lindsaar <mikel@test.lindsaar.net.au>'   subject 'first multipart email sent mail'    text_part     body 'this plain text'   end    html_part     content_type 'text/html; charset=utf-8'     body '<h1>this html</h1>'   end end

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).
