Request: Provide a constructor (like Regex( . . . ) vs r". . . ")

[ryofurue]

It would be nice if Glob provides a constructor that takes a regular String and converts it to a Glob.

The motivation is the same as #27 ; that is, it would be nice if standard string manipulations are available, but my request draws an analogy with Regex:

julia> a = "hello"
"hello"

julia> r1 = r".*$(a)\.jpg"
r".*$(a)\.jpg"

julia> r2 = Regex(".*$(a)\\.jpg")
r".*hello\.jpg"

You can make either a FilenameMatch or GlobMatch object directly, since the macro is just a simple wrappers over calling one of those. Like regex (and other templates like printf, etc.), it can be sometime risky to generate them from code though instead of using literals, as you risk introducing meta-characters that causes them match more than you intended

Thanks! I confirm that the following code works.

using Glob
a = "hello"
#g = Glob.FilenameMatch("$(a).jpg")
g = Glob.GlobMatch("$(a).jpg")
@show g
for file in readdir(g)
  println("Found $(file)")
end

I observe that GlobMatch isn't exported from Glob and that FilenameMatch doesn't work with readdir().

Understood, but I don't quite know what your intention is. Is your point that one shouldn't use the Regex constructor?

I don't know that it needs to be exported, though it should at least be marked public now. Calling readdir with an fnmatch requires making an array of them, since each fnmatch can only match one part of the filename
