I'm going to revise this SRFI as follows, unless someone thinks something should be discussed further. Remove all design related to versioning. Add a comment about why versions are not in file names: it's too controversial.
Good.
Require encoding the set of characters: #\%, #\., #\x0 to #\x1F, #\<, #\>, #\:, #\", #\/, #\\, #\|, #\?, and #\*. Require not encoding all other characters.
I think this is fine though the list looks pretty arbitrary.
(for example, why are #\{, #\}, #\[, #\], #\(, and #\) not
encoded?) I think it's fine that if a library name does not
map to a file name accepted by some who-knows-what file system
or operating system, too bad, pick a different name or curse
the system. If you have reasons for picking these chars for
encoding and not others, you probably need to say why, in a
footnote or endnote perhaps.
Implicit file name prefix is "main". Avoid conflicts by mapping (--- main) to "---/_main.sls", (--- _main) to "---/__main.sls", and so on.
Fine.
Ordering of an implicit file name match relative to a non-implicit filename match is not specified.
Fine.
Rephrase to state that files conforming to this SRFI must have only onelibrary per file. (Thus allowing implementations which support this SRFI to also support files which do not conform to this SRFI.)
Fine.
Rephrase to state that cross-implementation files, i.e. those without an implementation-specific file name extension, must contain the library as a standard library form as the first syntactic datum which the standardread procedure would return.
This sounds fine by me. I'd like to know Will's opinion.
State that implementations must support implementation-specific fileswith the same format as cross-implementation files, but implementationsmay also support other formats.
The "must" should be "may". I can imagine an implementation that does not wanting to provide implementation-specific files.
(Because of other parts of this SRFI, there are implied restrictions that implementation-specific files conforming to this SRFI must have only one library per file and that such files' path name must represent the name of the contained library (excluding the version).)
I don't know what you're referring to exactly but I don't think you should say much (or anything) about what goes in implementation-specific files.
Rename SCHEME_LIBRARY_SEARCH_PATHS to SCHEME_LIBRARY_PATHS.
SCHEME_LIBRARY_PATH, yes. :-)
Remove the restriction that search paths must be independent. (Wehaven't discussed this. Thinking about it more, I don't think there isenough justification for this restriction.)
Yes. I believe these changes will make a much better SRFI. Thanks for all the effort. Aziz,,,
