View Source Earmark.Options (Earmark v1.4.39)
This is a superset of the options that need to be passed into EarmarkParser.as_ast/2
The following options are proper to Earmark only and therefore explained in detail
compact_output: boolean indicating to avoid indentation and minimize whitespaceeex: Allows usage of anEExtemplate to be expanded to markdown before conversionfile: Name of file passed in from the CLIline: 1 but might be set to an offset for better error messages in some integration casessmartypants: boolean use Smarty Pants in the outputignore_strings,postprocessorandregistered_processors: processors that modify the AST returned fromEarmarkParser.as_ast/
2before rendering (postbecause preprocessing is done on the markdown, e.g.eex) Refer to the moduledoc of Earmark.Transformfor details
All other options are passed onto EarmarkParser.as_ast/2
Summary
Functions
Make a legal and normalized Option struct from, maps or keyword lists
Allows to compute the path of a relative file name (starting with "./") from the file in options
and return an updated options struct
A convenience constructor
Functions
Make a legal and normalized Option struct from, maps or keyword lists
Without a param or an empty input we just get a new Option struct
iex(1)> { make_options(), make_options(%{}) } { {:ok, %Earmark.Options{}}, {:ok, %Earmark.Options{}} }
The same holds for the bang version of course
iex(2)> { make_options!(), make_options!(%{}) } { %Earmark.Options{}, %Earmark.Options{} }
We check for unallowed keys
iex(3)> make_options(no_such_option: true) {:error, [{:warning, 0, "Unrecognized option no_such_option: true"}]}
Of course we do not let our users discover one error after another
iex(4)> make_options(no_such_option: true, gfm: false, still_not_an_option: 42) {:error, [{:warning, 0, "Unrecognized option no_such_option: true"}, {:warning, 0, "Unrecognized option still_not_an_option: 42"}]}
And the bang version will raise an Earmark.Error as excepted (sic)
iex(5)> make_options!(no_such_option: true, gfm: false, still_not_an_option: 42) ** (Earmark.Error) [{:warning, 0, "Unrecognized option no_such_option: true"}, {:warning, 0, "Unrecognized option still_not_an_option: 42"}]
Some values need to be numeric
iex(6)> make_options(line: "42") {:error, [{:error, 0, "line option must be numeric"}]}
iex(7)> make_options(%Earmark.Options{footnote_offset: "42"}) {:error, [{:error, 0, "footnote_offset option must be numeric"}]}
iex(8)> make_options(%{line: "42", footnote_offset: nil}) {:error, [{:error, 0, "footnote_offset option must be numeric"}, {:error, 0, "line option must be numeric"}]}
Allows to compute the path of a relative file name (starting with "./") from the file in options
and return an updated options struct
iex(9)> options = %Earmark.Options{file: "some/path/xxx.md"} ...(9)> options = relative_filename(options, "./local.md") ...(9)> options.file "some/path/local.md"
For your convenience you can just use a keyword list
iex(10)> options = relativefilename([file: "some/path/.md", breaks: true], "./local.md") ...(10)> {options.file, options.breaks} {"some/path/local.md", true}
If the filename is not absolute it just replaces the file in options
iex(11)> options = %Earmark.Options{file: "some/path/xxx.md"} ...(11)> options = relative_filename(options, "local.md") ...(11)> options.file "local.md"
And there is a special case when processing stdin, meaning that file: nil we replace file
verbatim in that case
iex(12)> options = %Earmark.Options{} ...(12)> options = relative_filename(options, "./local.md") ...(12)> options.file "./local.md"
