Module: RubyLens::Index::SourcePath

Defined in:
lib/rubylens/index/source_path.rb

Overview

Maps Rubydex document and location URIs back to workspace source paths.

Constant Summary collapse

ENCODED_FILE_URI =

The canonical shape Rubydex emits: an empty authority and a percent-encoded absolute path built from RFC 2396 path characters. Anything else falls back to full URI parsing below.

%r{\Afile://(/(?:[A-Za-z0-9\-_.!~*'()/:@&=+$,;]|%[0-9A-Fa-f]{2})*)\z}

Class Method Details

.from_file_uri(uri_string) ⇒ Object

Rubydex 0.2.9 percent-encodes file URIs and Location#to_file_path returns the path still encoded, so decode the URI ourselves.
