Finding All Files Whose Name Match a Regular Expression

Problem

You want to find all files whose names match a traditional shell regular expression (for example .). All known as globbing.

Solution

Use the function glob below:

500 Can't connect to 127.0.0.1:8778 (connect: Connection refused)

For example:

500 Can't connect to 127.0.0.1:8778 (connect: Connection refused)

Discussion

It is simple to find files matching a regular expression. You just convert the file name to a string, and use regexp-match to test. However the regular expression syntax is different to the traditional shell regular expression syntax. For example the pattern . will not work. Hence you must convert the traditional syntax to that accepted by regexp-match. That is the function of glob->regexp. From there it is simple to construct a glob matcher from MzScheme's library of regular expression and path manipulation functions.
