View Source Rewrite.DotFormatter behaviour (rewrite v1.0.1)
Provides an alternative API to the Elixir dot formatter.
The DotFormatter
has the same functionality as the code that provides the
mix format
task. But DotFormatter
provides a struct for the evaluated
formatter config to provide a more convenient API.

In case of an conflict, an :error
tuple is returned. A conflicting file is a
file that is referenced by more than one formatter.
The formatter is a two arity function that takes a string as input and
options to format the string. For more information see formatter_for_file/3
.
@spec format( t() | nil, keyword() ) :: :ok | {:error, Rewrite.DotFormatterError.t()}

.
@spec format_quoted( String.t(), keyword() ) :: {:ok, String.t()} | {:error, Rewrite.DotFormatterError.t()}
A convenience function for format_quoted/4
to format a string.
This function reads the %DotFormatter{}
with the given opts

format_quoted/4
. The used file name defaults to nofile.ex
and can be set
in the opts
.
Options

in case of failure.
Returns a formatter function to be used for the given file
.
The returned function takes a string or an Elixir AST and returns the formatted
string. The option :from
takes the value :string

to determine
which input type is used by the formatter, defaulting to :string
.
The function also accepts the same options as Code.format_string!/2
, these
are used when the formatter is called.

.
This functions ignores the sub-formatters of the given dot_formatter

file in the current directory or the given

project.

project is given to the function, the formatter is searched
in the project and the latest version from the source is used. As a fallback,
it will search the file system for the required files.
The function returns a %DotFormatter{}
struct with all sub-formatters.

- a list of{old, new}
tuples to replace plugins in the formatter.ignore_unknown_deps
