|
||
|
||
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?
