Docutils-develop mailing list
<https://docutils.sourceforge.io/docs/user/mailing-lists.html#docutils-develop>.
Parameters:
* `source_class` **required**: The class for dynamically created source
objects. Typically `io.FileInput` or `io.StringInput`.
* `source`: Type depends on `source_class`:
- If `source_class` is `io.FileInput`: Either a file-like object
(must have 'read' and 'close' methods), or ``None``
(`source_path` is opened). If neither `source` nor
`source_path` are supplied, `sys.stdin` is used.
- If `source_class` is `io.StringInput` **required**:
The input as either a `bytes` object (ensure the 'input_encoding'
setting matches its encoding) or a `str` object.
* `source_path`: Type depends on `source_class`:
- `io.FileInput`: Path to the input file, opened if no `source`
supplied.
- `io.StringInput`: Optional. Path to the file or name of the
object that produced `source`. Only used for diagnostic output.
* `destination_class` **required**: The class for dynamically created
destination objects. Typically `io.FileOutput` or `io.StringOutput`.
* `destination`: Type depends on `destination_class`:
- `io.FileOutput`: Either a file-like object (must have 'write' and
'close' methods), or ``None`` (`destination_path` is opened). If
neither `destination` nor `destination_path` are supplied,
`sys.stdout` is used.
- `io.StringOutput`: Not used; pass ``None``.
* `destination_path`: Type depends on `destination_class`:
- `io.FileOutput`: Path to the output file. Opened if no `destination`
supplied.
- `io.StringOutput`: Path to the file or object which will receive the
output; optional. Used for determining relative paths (stylesheets,
source links, etc.).
* `reader`: A `docutils.readers.Reader` object.
* `reader_name`: Name or alias of the Reader class to be instantiated if
no `reader` supplied.
* `parser`: A `docutils.parsers.Parser` object.
* `parser_name`: Name or alias of the Parser class to be instantiated if
no `parser` supplied.
* `writer`: A `docutils.writers.Writer` object.
* `writer_name`: Name or alias of the Writer class to be instantiated if
no `writer` supplied.
* `settings`: A runtime settings (`docutils.frontend.Values`) object, for
dotted-attribute access to runtime settings. It's the end result of the
`SettingsSpec`, config file, and option processing. If `settings` is
passed, it's assumed to be complete and no further setting/config/option
processing is done.
* `settings_spec`: A `docutils.SettingsSpec` subclass or object. Provides
extra application-specific settings definitions independently of
components. In other words, the application becomes a component, and
its settings data is processed along with that of the other components.
Used only if no `settings` specified.
* `settings_overrides`: A dictionary containing application-specific
settings defaults that override the defaults of other components.
Used only if no `settings` specified.
* `config_section`: A string, the name of the configuration file section
for this application. Overrides the ``config_section`` attribute
defined by `settings_spec`. Used only if no `settings` specified.
* `enable_exit_status`: Boolean; enable exit status at end of processing?
