This is the step I don't understand.
How do I use the normal diff format for my patch?
I am still waiting for an answer for how the diff command works.
have you never heard of a man page?? at your *nix command line, issue
"man diff" without the quotes... learn man, use man, love man ;)
Steady on chaps. Let's just assume that what he's asking is how to use
diff when fixing a bug or making some other change in the context of
this group of projects, i.e. FPC and Lazarus.
When I specifically asked this question just a couple of days ago I was
told that the expected format was unified, not normal. Hence with the
original file in a directory ./old:
diff -u old/testSinPi.pas testSinPi.pas >testSinPi.diff
where the diff file allows the changes to be incorporated by the developers.
Now I do agree that usage of man is a very basic skill if one hopes to
do anything with unix (including Linux et al.). However anybody who
wants to teach this point to a beginner really should be pointing out a
few additional facts:
* The output of man goes through a pager program. For a shell session
(i.e. not using xman etc.) you exit from this using q
* At the bottom of the manpage there is a SEE ALSO section which
frequently cites other commands, each with their own manpage.
* When a manpage is cited like readline(3), you access it using man 3
readline
* You can get a list of related commands etc. using the apropos
command, i.e. like apropos diff or apropos diff |less
* And finally, there are some commands, such as svn, which don't have
good manpages. In that context the correct question is "how do I use svn
to do X in the context of project Y", not "how does svn work".
Or at least that's how I'd have put it when I was being paid to teach or
support.
