Glob * and ? never match across / or \, so any item containing a slash is filtered out #114

What's wrong

ResolveGlob (TextFilter/TextFilter.cs, around lines 406–416) compiles every token with Glob.Parse from DotNet.Glob. DotNet.Glob is a file-path glob library, so * and ? stop at path separators (/ and \). TextFilter filters arbitrary text, and GetHint and the README describe * and ? as plain wildcards with no path semantics. As soon as the text contains a slash or backslash, a wildcard can no longer reach across it.

Failure scenario (reproduced)

A filter box over a list of file paths: the user types *readme* and docs/readme.md disappears, while readme.md stays. The same thing happens with:

It affects every match option and both case settings. Paths, URLs, dates (1/2/2026), fractions and band names are all ordinary things to filter.

Repro (MSTest, all fail today):

[TestMethod] public void StarMatchesAcrossSlash() => Assert.IsTrue(TextFilter.IsMatch("AC/DC", "AC*", TextFilterType.Glob, TextFilterMatchOptions.ByWordAny));
[TestMethod] public void QuestionMarkMatchesSlash() => Assert.IsTrue(TextFilter.IsMatch("1/2", "1?2", TextFilterType.Glob, TextFilterMatchOptions.ByWordAny));
[TestMethod] public void StarMatchesPath() => Assert.IsTrue(TextFilter.IsMatch("src/Foo.cs", "*.cs", TextFilterType.Glob, TextFilterMatchOptions.ByWholeString));
[TestMethod] public void StarMatchesBackslashPath() => Assert.IsTrue(TextFilter.IsMatch(@"C:\temp\a.txt", "*.txt", TextFilterType.Glob, TextFilterMatchOptions.ByWholeString));
[TestMethod] public void FilterKeepsPathItems() { var r = TextFilter.Filter(new[] { "docs/readme.md", "readme.md" }, "*readme*").ToList(); Assert.AreEqual(2, r.Count); }

Suggested fix

Either of these:

• Translate glob tokens to regex yourself (preferred): * → .*, ? → ., keep [...] ranges (handling a half-typed range the way the current code does), and Regex.Escape everything else, anchored with ^…$. This can reuse the existing regex cache, timeout, and CultureInvariant | IgnoreCase handling, and it drops a dependency whose semantics don't fit.
• Or keep DotNet.Glob and map / and \ to a private-use character (e.g. U+E000) in both the text and the pattern before matching.

Acceptance: the five tests above pass, and the existing glob tests still pass.
