def self.handle_error(e, re_raise: true, io: $stderr)
unless e.is_a?(SyntaxError)
io.puts("SyntaxSuggest: Must pass a SyntaxError, got: #{e.class}")
raise e
end
file = PathnameFromMessage.new(e.message, io: io).call.name
raise e unless file
io.sync = true
call(
io: io,
source: file.read,
filename: file
)
raise e if re_raise
end
Takes a SyntaxError exception, uses the error message to locate the file. Then the file will be analyzed to find the location of the syntax error and emit that location to stderr.
Example:
Example
begin require 'bad_file' rescue => e SyntaxSuggest.handle_error(e) end
By default it will re-raise the exception unless ‘re_raise: false`. The message output location can be configured using the `io: $stderr` input.
If a valid filename cannot be determined, the original exception will be re-raised (even with ‘re_raise: false`).
