question about basic Filesystem usage for the Solid hex for Liquid templating. Cross-posting from Github [basic Filesystem usage syntax · Issue #96 · edgurgel/solid · GitHub](https://github.com/edgurgel/solid/issues/96)

what am I missing for filesystem usage in a simple Phoenix index action below?

```elixir
def index(conn, _params) do
    template_path = "/lib/app_web/templates/liquid/"
    file_system = Solid.LocalFileSystem.new(template_path)
    text = Solid.LocalFileSystem.full_path(file_system, "hello")
    render(conn, text)
end

```

```elixir
/lib/app_web/templates/liquid/_hello.liquid
hello

```

gives

```elixir
    ** (FunctionClauseError) no function clause matching in String.match?/2
        (elixir 1.12.2) lib/string.ex:2259: String.match?(%Solid.LocalFileSystem{pattern: "_%s.liquid", root: "/lib/app_web/templates/liquid/"}, ~r/^[^.\/][a-zA-Z0-9_\/]+$/)
        (solid 0.10.0) lib/solid/file_system.ex:84: Solid.LocalFileSystem.full_path/2

```

no doubt missing some basic config or awareness around the correct syntax

maybe you need a `Path.absname("foo")` eg

template\_path = `Path.absname("/lib/app_web/templates/liquid/")`

also the docs for solid are not coherent on `Solid.LocalFileSystem.full_path` according to code the argument order is `Solid.LocalFileSystem.full_path( "hello", file_system)` (yours is opposite) - maybe PR a doc fix..
