I'm happy to announce the release of guile-file-names 0.2.

The (file-names) module provides methods for manipulating file names.
Its design distinguishes between the human-friendly string format of
filenames ("/usr/bin/guile") and a more Scheme-friendly representation
to take out all the little nuisances of working with file names.

This release sees bugs fixed, under-the-hood improvements, and new
features added.  See below for an excerpt from the NEWS file.

If you use the library, please consider reporting any bugs you encounter
or feature requests you might have on the issue tracker on Gitlab:

Direct email to me is also fine, if you don't have a Gitlab account.


** Features

*** Native file-globbing sub-module
A new sub-module (file-names glob) has been added.  This module
provides the <file-name> method glob, which is used to perform
"file-globbing."   File-globbing is the method of finding multiple
files, e.g. at the shell, by matching wildcards
(e.g. "/usr/lib/*.so").

glob supports shell-style wildcards (*, ?, [] and **) as
well as full regular expressions.

*** string->file-name now takes optional keyword arguments
This allows you to override system- or parsed- defaults for the
volume, separator and case-sensitivity.

*** New <file-name> methods remove-prefix and remove-prefix!
These new methods convert an absolute file name to a relative one by
removing a leading directory prefix.

*** Specialized write and display methods for <file-name> objects

Running write or display on a <file-name> object now prints a
recognizable string representation of the file name rather than the
default cryptic GOOPS-object format:

scheme@(guile-user)> (use-modules (file-names))
scheme@(guile-user)> (define f (string->file-name "/usr/bin/guile"))
scheme@(guile-user)> (simple-format #t "~a\n" f)
#<<file-name> /usr/bin/guile>

** Bugs

*** Resolving an absolute file name
It is now an explicit error if there are double-dots at the root of
the file name (e.g. "/../foo/bar").  Also, a bug was fixed where
sequential double-dots ("../../../blah.txt") were not handled correctly.

*** file-name=? now behaves correctly for relative file names.
