+# match any negative filters. The full glob syntax is described in the `glob`
+# crate documentation <https://docs.rs/glob/latest/glob/struct.Pattern.html>,

+# If the "PATH" variable is passed to the server then it'll be also used for

+# Example: pass_environment = ["PATH", "LD_LIBRARY_PATH"]
+#
+# Another option is to allow everything and then use negative filters to exclude
+# variables which cause problems - variables like WINDOWID set by the terminal
+# emulator which would cause `lspmux` to spawn a new language server for every
+# connected client, defeating its purpose.
