Add function #'ADD-LOCAL-PROJECTS-TO-MANIFEST

[EuAndreh]

Fixes #83

I tried to copy the same ideas of pathname handling and stream writing from other functions of the quicklisp-client package.

Maybe add to the docstring a tip saying to use (ql:write-asdf-manifest-file) and (ql:register-local-projects) before using (ql:add-local-projects-to-manifest) in order to keep all up-to-date?

Thanks for working on this. I think I'd like slightly different behavior:

• Local project systems should be added to the manifest automatically
• A new keyword argument, :exclude-local-projects, should exclude those projects
• The local projects should take precedence over quicklisp built-in projects

For that final point, I don't know if that means the local-projects must precede or succeed the Quicklisp-provided systems...double check the manifest file code in buildapp to be sure.

Do you feel like revising your code to do that? If not, I can look into doing it myself this weekend.

[quicklisp]

The new keyword argument should be added to write-asdf-manifest-file and default to nil.

[EuAndreh]

Sure, I'll do it.

Thanks for your review.

[EuAndreh]

Still need to check the precedence of local systems. Still working on that.

[EuAndreh]

The function (asdf-directive-files '((:manifest-file "manifest/file/path.txt")), returns the system in the same order as in the manifest file. All functions that call it and beyond don't reverse the result.
Thus, if local-projects systems are first in the manifest file, they get precedence.

Did I implement it properly?
Is that all?

[quicklisp]

One last thing - if exclude-local-projects is nil, call register-local-projects before saving the manifest?

[EuAndreh]

Done

[quicklisp]

Thank you, things look great! There's one last thing that I noticed that might be a potential issue.

Entries in the manifest file should be written in relative form if the manifest file is in a parent directory of the system file. I use enough-namestring for that in write-asdf-manifest-file. Could you please make sure manifest entries are relative if applicable?

[EuAndreh]

Sure, I'm glad I can help.

[EuAndreh]

I used the same variable names as the original code.
I didn't put the verification (and system-file (enough-namestring system-file output-file)) because the generated list is already "valid" (withou nil atoms).
