;; 1. Customization: use-editable variables to customize
|
||
|
;; doctest-mode.
|
||
|
;;
|
||
|
;; 2. Fonts: defines new font-lock faces.
|
||
|
;;
|
||
|
;; 3. Constants: various consts (mainly regexps) used by the rest
|
||
|
;; of the code.
|
||
|
;;
|
||
|
;; 4. Syntax Highlighting: defines variables and functions used by
|
||
|
;; font-lock-mode to perform syntax highlighting.
|
||
|
;;
|
||
|
;; 5. Source code editing & indentation: commands used to
|
||
|
;; automatically indent, dedent, & handle prompts.
|
||
|
;;
|
||
|
;; 6. Code Execution: commands used to start doctest processes,
|
||
|
;; and handle their output.
|
||
|
;;
|
||
|
;; 7. Markers: functions used to insert markers at the start of
|
||
|
;; doctest examples. These are used to keep track of the
|
||
|
;; correspondence between examples in the source buffer and
|
||
|
;; results in the output buffer.
|
||
|
;;
|
||
|
;; 8. Navigation: commands used to navigate between failed examples.
|
||
|
;;
|
||
|
;; 9. Replace Output: command used to replace a doctest example's
|
||
|
;; expected output with its actual output.
|
||
|
;;
|
||
|
;; 10. Helper functions: various helper functions used by the rest
|
||
|
;; of the code.
|
||
|
;;
|
||
|
;; 11. Emacs compatibility functions: defines compatible versions of
|
||
|
;; functions that are defined for some versions of emacs but not
|
||
|
;; others.
|
||
|
;;
|
||
|
;; 12. Doctest Results Mode: defines doctest-results-mode, which is
|
||
|
;; used for the output generated by doctest.
|
||
|
;;
|
||
|
;; 13. Doctest Mode: defines doctest-mode itself.

Two classes are registered:

`doctest-docstring'
|

|
|

|
Used to edit docstrings containing doctest examples in python-

strings (\"\"\"). In order to avoid confusing start-string
|

|
markers and end-string markers, all triple-quote strings in the

|
buffer are treated as submode regions (even if they're not
|
||
|
actually docstrings). Use (C-c % C-d) to insert a new doctest-
|
||
|
docstring region. When `doctest-execute' (C-c C-c) is called
|
||
|
inside a doctest-docstring region, it executes just the current
|
||
|
docstring. The globals for this execution are constructed by
|
||
|
importing the current buffer's contents in Python.
|
||
|
|
||
|
`doctest-example'
|
||
|
|
||
|
Used to edit doctest examples in text-editing modes, such as
|
||
|
`rst-mode' or `text-mode'. Docstring submode regions start with
|
||
|
optionally indented prompts (>>>) and end with blank lines. Use
|
||
|
(C-c % C-e) to insert a new doctest-example region. When
|
||
|
`doctest-execute' (C-c C-c) is called inside a doctest-example
|
||
|
region, it executes all examples in the buffer.

`doctest-mode' defines three kinds of line, each of which is

|
treated differently:
|
||
|
|
||
|
- 'Source lines' are lines consisting of a Python prompt
|
||
|
('>>>' or '...'), followed by source code. Source lines are
|
||
|
colored (similarly to `python-mode') and auto-indented.
|
||
|
|
||
|
- 'Output lines' are non-blank lines immediately following
|
||
|
source lines. They are colored using several doctest-
|
||
|
specific output faces.
|
||
|
|
||
|
- 'Text lines' are any other lines. They are not processed in
|
||
|
any special way.
