class StateMachineWS(StateMachine): (source)
Known subclasses: docutils.parsers.rst.states.NestedStateMachine
, docutils.parsers.rst.states.RSTStateMachine
, docutils.statemachine.SearchStateMachineWS
`StateMachine` subclass specialized for whitespace recognition. There are three methods provided for extracting indented text blocks: - `get_indented()`: use when the indent is unknown. - `get_known_indented()`: use when the indent is known for all lines. - `get_first_known_indented()`: use when only the first line's indent is known.

Inherited from StateMachine
:
Method | __init__ |
Initialize a `StateMachine` object; add state objects. |
Method | abs |
Return line number of current line (counting from 1). |
Method | abs |
Return line offset of current line, from beginning of file. |
Method | add |
Initialize & add a `state_class` (`State` subclass) object. |
Method | add |
Add `state_classes` (a list of `State` subclasses). |
Method | at |
Return 1 if the input is at or before beginning-of-file. |
Method | at |
Return 1 if the input is at or past end-of-file. |
Method | attach |
The `observer` parameter is a function or bound method which takes two arguments, the source and offset of the current line. |
Method | check |
Examine one line of input for a transition match & execute its method. |
Method | detach |
Undocumented |
Method | error |
Report error details. |
Method | get |
Return source of line at absolute line offset `line_offset`. |
Method | get |
Return (source, line) tuple for current or given line number. |
Method | get |
Return current state object; set it first if `next_state` given. |
Method | get |
Return a contiguous block of text. |
Method | goto |
Jump to absolute line offset `line_offset`, load and return it. |
Method | insert |
Undocumented |
Method | is |
Return True if the next line is blank or non-existent. |
Method | next |
Load `self.line` with the `n`'th next line and return it. |
Method | notify |
Undocumented |
Method | previous |
Load `self.line` with the `n`'th previous line and return it. |
Method | run |
Run the state machine on `input_lines`. Return results (a list). |
Method | runtime |
Initialize `self.states`. |
Method | unlink |
Remove circular references to objects no longer required. |
Instance Variable | current |
The name of the current state (key to `self.states`). |
Instance Variable | debug |
Debugging mode on/off. |
Instance Variable | initial |
The name of the initial state (key to `self.states`). |
Instance Variable | input |
`StringList` of input lines (without newlines). Filled by `self.run()`. |
Instance Variable | input |
Offset of `self.input_lines` from the beginning of the file. |
Instance Variable | line |
Current input line. |
Instance Variable | line |
Current input line offset from beginning of `self.input_lines`. |
Instance Variable | observers |
List of bound methods or functions to call whenever the current line changes. Observers are called with one argument, ``self``. Cleared at the end of `run()`. |
Instance Variable | states |
Mapping of {state_name: State_object}. |
Return an indented block and info. Extract an indented block where the indent is known for the first line and unknown for all other lines. :Parameters: - `indent`: The first line's indent (# of columns/characters). - `until_blank`: Stop collecting at the first blank line if true (1). - `strip_indent`: Strip `indent` characters of indentation if true (1, default). - `strip_top`: Strip blank lines from the beginning of the block. :Return: - the indented block, - its indent, - its first line offset from BOF, and - whether or not it finished with a blank line.
Return a block of indented lines of text, and info. Extract an indented block where the indent is unknown for all lines. :Parameters: - `until_blank`: Stop collecting at the first blank line if true. - `strip_indent`: Strip common leading indent if true (default). :Return: - the indented block (a list of lines of text), - its indent, - its first line offset from BOF, and - whether or not it finished with a blank line.
Return an indented block and info. Extract an indented block where the indent is known for all lines. Starting with the current line, extract the entire text block with at least `indent` indentation (which must be whitespace, except for the first line). :Parameters: - `indent`: The number of indent columns/characters. - `until_blank`: Stop collecting at the first blank line if true. - `strip_indent`: Strip `indent` characters of indentation if true (default). :Return: - the indented block, - its first line offset from BOF, and - whether or not it finished with a blank line.
