Method: BetterErrors.editor=

Defined in:
lib/better_errors.rb

+ (Object) BetterErrors.editor=(sym) + (Object) BetterErrors.editor=(str) + (Object) BetterErrors.editor=(proc)

Configures how Better Errors generates open-in-editor URLs.

Overloads:

  • + (Object) BetterErrors.editor=(sym)

    Uses one of the preset editor configurations. Valid symbols are:

    • :textmate, :txmt, :tm
    • :sublime, :subl, :st
    • :macvim

    Parameters:

    • sym (Symbol)
  • + (Object) BetterErrors.editor=(str)

    Uses str as the format string for generating open-in-editor URLs.

    Use %{file} and %{line} as placeholders for the actual values.

    Examples:

    BetterErrors.editor = "my-editor://open?url=%{file}&line=%{line}"

    Parameters:

    • str (String)
  • + (Object) BetterErrors.editor=(proc)

    Uses proc to generate open-in-editor URLs. The proc will be called with file and line parameters when a URL needs to be generated.

    Your proc should take care to escape file appropriately with URI.encode_www_form_component (please note that URI.escape is not a suitable substitute.)

    Examples:

    BetterErrors.editor = proc { |file, line|
  "my-editor://open?url=#{URI.encode_www_form_component file}&line=#{line}"
}

    Parameters:

    • proc (Proc)
