import paths with spaces

[Derick Eddington]

Say I have a directory filename with spaces in it and I want to import libraries from that directory, I should be able to do:

(import (|Some Dir| my-lib))
    or
(import (Some\x20;Dir my-lib))

but this currently does not work. With the \xXX; it borks on the symbol bug I just reported, and with the |X X| it does:

Unhandled exception
 Condition components:
   1. &error
   2. &message: "cannot find library"
   3. &irritants: ((Ikarus\x20;Misc continuable-interrupts))

The library name should ideally describe the functionality of the library, not the location in which it is stored on the file system. The file name is secondary and, eventually, there will be a way to specify your own library->file-name mapping. For now, please use (ikarus-misc continuable-interrupts), without spaces.

There is a usability issue here of course in that ikarus did not tell you *why* it failed and where it looked. I'll fix that. Thanks.

As of revision 1087:

If you have a script like:

#!/usr/bin/env scheme-script
(import (|some dir| my-lib))

and Ikarus cannot find the library, it will say:

Unhandled exception:
 Condition components:
   1. &error
   2. &who: expander
   3. &message: "cannot locate library in library-path"
   4. &library-resolution:
       library: (some\x20;dir my-lib)
       files: ("./some%20dir/my-lib.ss" "/Users/ikarus/.opt/lib/ikarus/some%20dir/my-lib.ss")

which should be a good clue about how to go about fixing the problem.

After all, spaces do work, just not how you'd expected them to. :-)

Why, in the current default library->file-name mapper, does the symbol's \x20; get turned into "%20" instead of a space? Just wondering.

(Also JTMI, I agree with the reasoning about libraries' names corresponding to their functionality; I was goofing around with an editor and its projects folders...)

I don't have a good reason really. You have to escape some
characters and
space ended up in that set. The current mapper is incomplete anyways
and
there are cases where it does not produce proper file names. But
it's kind
of good enough for now, so it won't be generalized anytime soon.
