Package epydoc.markup
Markup language support for docstrings. Each submodule defines a
parser for a single markup language. These parsers convert an object's
docstring to a ParsedDocstring, a standard intermediate
representation that can be used to generate output.
ParsedDocstrings support the following operations:
The parse() function provides a single
interface to the epydoc.markup package: it takes a docstring
and the name of a markup language; delegates to the appropriate parser;
and returns the parsed docstring (along with any errors or warnings that
were generated).
The ParsedDocstring output generation methods
(to_format()) use a DocstringLinker to link the docstring
output with the rest of the documentation that epydoc generates.
DocstringLinkers are currently responsible for translating
two kinds of crossreference:
A parsed docstring's fields can be extracted using the ParsedDocstring.split_fields() method. This
method divides a docstring into its main body and a list of Fields, each of which encodes a single
field. The field's bodies are encoded as
ParsedDocstrings.
Markup errors are represented using ParseErrors. These exception classes record
information about the cause, location, and severity of each error.
The epydoc.markup module also defines several utility
functions, such as wordwrap, plaintext_to_latex, and plaintext_to_html, which are used by
several different markup language parsers.
| Classes |
ParsedDocstring |
A standard intermediate representation for parsed docstrings that can
be used to generate output. |

The contents of a docstring's field. |
DocstringLinker |
A translator for crossreference links into and out of a
ParsedDocstring. |
| Exceptions |
| Errors and Warnings |
ParseError |
The base class for errors generated while parsing docstrings. |
| Function Summary |
ParsedDocstring
|
parse(docstring,
markup,
errors,
**options)
Parse the given docstring, and use it to construct a
ParsedDocstring. |
string
|
plaintext_to_html(str)
Return an HTML string that encodes the given plaintext string. |
| |
_parse_warn(estr)
Print a warning message. |
| Utility Functions |
string
|
wordwrap(str,
indent,
right,
startindex)
Word-wrap the given string. |
string
|
plaintext_to_latex(str,
nbsp,
breakany)
Return a LaTeX string that encodes the given plaintext string. |
ParsedDocstring
|
parse_type_of(obj)
Return a ParsedDocstring that encodes the type of the given
object. |
parse(docstring,
markup='plaintext',
errors=None,
**options)
Parse the given docstring, and use it to construct a
ParsedDocstring. If any fatal ParseErrors are
encountered while parsing the docstring, then the docstring will be
rendered as plaintext, instead.
-
- Parameters:
docstring -
The docstring to encode.
(type=string)
markup -
The name of the markup language that is used by the docstring.
If the markup language is not supported, then the docstring will
be treated as plaintext. The markup name is case-insensitive.
(type=string)
errors -
A list where any errors generated during parsing will be
stored. If no list is specified, then fatal errors will generate
exceptions, and non-fatal errors will be ignored.
(type=list of ParseError)
- Returns:
-
A
ParsedDocstring that encodes the
contents of docstring.
(type=ParsedDocstring)
- Raises:
ParseError -
If errors is None and an error is
encountered while parsing.
|
wordwrap(str,
indent=0,
right=73,
startindex=0)
Word-wrap the given string. All sequences of whitespace are
converted into spaces, and the string is broken up into lines, where
each line begins with indent spaces, followed by one or
more (space-deliniated) words whose length is less than
right-indent. If a word is longer than
right-indent characters, then it is put on its own
line.
-
- Parameters:
str -
The string that should be word-wrapped.
(type=int)
indent -
The left margin of the string. indent spaces will
be inserted at the beginning of every line.
(type=int)
right -
The right margin of the string.
(type=int)
startindex -
The index at which the first line starts. This is useful if
you want to include other contents on the first line.
(type=int)
- Returns:
-
A word-wrapped version of
str.
(type=string)
|
plaintext_to_latex(str,
nbsp=0,
breakany=0)
-
- Parameters:
nbsp -
Replace every space with a non-breaking space
('~').
breakany -
Insert hyphenation marks, so that LaTeX can break the
resulting string at any point. This is useful for small boxes
(e.g., the type box in the variable list table).
- Returns:
-
A LaTeX string that encodes the given plaintext string. In
particular, special characters (such as
'$' and
'_') are escaped, and tabs are expanded.
(type=string)
|
parse_type_of(obj)
-
- Parameters:
obj -
The object whose type should be returned as DOM document.
(type=any)
- Returns:
-
A
ParsedDocstring that encodes the type of the
given object.
(type=ParsedDocstring)
|
plaintext_to_html(str)
-
- Returns:
-
An HTML string that encodes the given plaintext string. In
particular, special characters (such as
'<' and
'&') are escaped.
(type=string)
|
_parse_warn(estr)
Print a warning message. If the given error has already been
printed, then do nothing.
-
|
SCRWIDTH
The default width with which text will be wrapped when formatting the
output of the parser.
-
- Type:
-
int
- Value:
|
