Barry Warsaw | ab0e86c | 1998-05-19 15:31:46 +0000 | [diff] [blame] | 2474 | hallucinogenic resemblance to `\\[py-end-of-def-or-class]' and |

| 2477 | And in earlier versions of Python mode, all 3 were tightly connected. |
Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2478 | Turned out that was more confusing than useful: the `goto start' and |
| 2479 | `goto end' commands are usually used to search through a file, and |
| 2480 | people expect them to act a lot like `search backward' and `search |
| 2481 | forward' string-search commands. But because Python `def' and `class' |
| 2482 | can nest to arbitrary levels, finding the smallest def containing |
| 2483 | point cannot be done via a simple backward search: the def containing |
| 2484 | point may not be the closest preceding def, or even the closest |
| 2485 | preceding def that's indented less. The fancy algorithm required is |
| 2486 | appropriate for the usual uses of this `mark' command, but not for the |
| 2487 | `goto' variations. |

Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2489 | So the def marked by this command may not be the one either of the |
| 2490 | `goto' commands find: If point is on a blank or non-indenting comment |
| 2491 | line, moves back to start of the closest preceding code statement or |
| 2492 | indenting comment line. If this is a `def' statement, that's the def |
| 2493 | we use. Else searches for the smallest enclosing `def' block and uses |
| 2494 | that. Else signals an error. |

| 2690 | the paren/bracket/brace nesting level at the start of the line is |

Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2692 | |
| 2693 | An initial line is in turn a `blank line' (contains nothing except |
Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2694 | possibly blanks or tabs), a `comment line' (leftmost non-blank |
| 2695 | character is `#'), or a `code line' (everything else). |
Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2696 | |
| 2697 | Comment Lines |
| 2698 | |
| 2699 | Although all comment lines are treated alike by Python, Python mode |
| 2700 | recognizes two kinds that act differently with respect to indentation. |
| 2701 | |
| 2702 | An `indenting comment line' is a comment line with a blank, tab or |
| 2703 | nothing after the initial `#'. The indentation commands (see below) |
Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2704 | treat these exactly as if they were code lines: a line following an |
Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2705 | indenting comment line will be indented like the comment line. All |
| 2706 | other comment lines (those with a non-whitespace character immediately |
Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2707 | following the initial `#') are `non-indenting comment lines', and |
| 2708 | their indentation is ignored by the indentation commands. |
Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2709 | |
| 2710 | Indenting comment lines are by far the usual case, and should be used |
Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2711 | whenever possible. Non-indenting comment lines are useful in cases |
| 2712 | like these: |
Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2713 | |
| 2714 | \ta = b # a very wordy single-line comment that ends up being |
| 2715 | \t #... continued onto another line |
| 2716 | |

Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2721 | Since the `#...' and `##' comment lines have a non-whitespace |
| 2722 | character following the initial `#', Python mode ignores them when |
| 2723 | computing the proper indentation for the next line. |

| 2725 | Continuation Lines and Statements |
| 2726 | |
| 2727 | The Python-mode commands generally work on statements instead of on |
| 2728 | individual lines, where a `statement' is a comment or blank line, or a |
| 2729 | code line and all of its following continuation lines (if any) |
| 2730 | considered as a single logical unit. The commands in this mode |
| 2731 | generally (when it makes sense) automatically move to the start of the |
Barry Warsaw | 7b0f568 | 1995-03-08 21:33:04 +0000 | [diff] [blame] | 2732 | statement containing point, even if point happens to be in the middle |
| 2733 | of some continuation line. |

| 2736 | @INDENTATION |
| 2737 | |
| 2738 | Primarily for entering new code: |
| 2739 | \t\\[indent-for-tab-command]\t indent line appropriately |
| 2740 | \t\\[py-newline-and-indent]\t insert newline, then indent |
Barry Warsaw | 27ee115 | 1997-12-03 05:03:44 +0000 | [diff] [blame] | 2741 | \t\\[py-electric-backspace]\t reduce indentation, or delete single character |
Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2742 | |
| 2743 | Primarily for reindenting existing code: |
| 2744 | \t\\[py-guess-indent-offset]\t guess py-indent-offset from file content; change locally |
| 2745 | \t\\[universal-argument] \\[py-guess-indent-offset]\t ditto, but change globally |
| 2746 | |
| 2747 | \t\\[py-indent-region]\t reindent region to match its context |
| 2748 | \t\\[py-shift-region-left]\t shift region left by py-indent-offset |
| 2749 | \t\\[py-shift-region-right]\t shift region right by py-indent-offset |
| 2750 | |
| 2751 | Unlike most programming languages, Python uses indentation, and only |
| 2752 | indentation, to specify block structure. Hence the indentation supplied |
| 2753 | automatically by Python-mode is just an educated guess: only you know |
| 2754 | the block structure you intend, so only you can supply correct |
| 2755 | indentation. |
| 2756 | |
| 2757 | The \\[indent-for-tab-command] and \\[py-newline-and-indent] keys try to suggest plausible indentation, based on |
| 2758 | the indentation of preceding statements. E.g., assuming |
| 2759 | py-indent-offset is 4, after you enter |
| 2760 | \tif a > 0: \\[py-newline-and-indent] |
| 2761 | the cursor will be moved to the position of the `_' (_ is not a |
| 2762 | character in the file, it's just used here to indicate the location of |
| 2763 | the cursor): |
| 2764 | \tif a > 0: |
| 2765 | \t _ |
| 2766 | If you then enter `c = d' \\[py-newline-and-indent], the cursor will move |
| 2767 | to |
| 2768 | \tif a > 0: |
| 2769 | \t c = d |
| 2770 | \t _ |
| 2771 | Python-mode cannot know whether that's what you intended, or whether |
| 2772 | \tif a > 0: |
| 2773 | \t c = d |
| 2774 | \t_ |
| 2775 | was your intent. In general, Python-mode either reproduces the |
| 2776 | indentation of the (closest code or indenting-comment) preceding |
| 2777 | statement, or adds an extra py-indent-offset blanks if the preceding |
| 2778 | statement has `:' as its last significant (non-whitespace and non- |
| 2779 | comment) character. If the suggested indentation is too much, use |
Barry Warsaw | 27ee115 | 1997-12-03 05:03:44 +0000 | [diff] [blame] | 2780 | \\[py-electric-backspace] to reduce it. |
Barry Warsaw | 7ae7768 | 1994-12-12 20:38:05 +0000 | [diff] [blame] | 2781 | |
| 2782 | Continuation lines are given extra indentation. If you don't like the |
| 2783 | suggested indentation, change it to something you do like, and Python- |
| 2784 | mode will strive to indent later lines of the statement in the same way. |
| 2785 | |
| 2786 | If a line is a continuation line by virtue of being in an unclosed |
| 2787 | paren/bracket/brace structure (`list', for short), the suggested |
| 2788 | indentation depends on whether the current line contains the first item |
| 2789 | in the list. If it does, it's indented py-indent-offset columns beyond |
| 2790 | the indentation of the line containing the open bracket. If you don't |
| 2791 | like that, change it by hand. The remaining items in the list will mimic |
| 2792 | whatever indentation you give to the first item. |
| 2793 | |
| 2794 | If a line is a continuation line because the line preceding it ends with |
| 2795 | a backslash, the third and following lines of the statement inherit their |
| 2796 | indentation from the line preceding them. The indentation of the second |
| 2797 | line in the statement depends on the form of the first (base) line: if |
| 2798 | the base line is an assignment statement with anything more interesting |
| 2799 | than the backslash following the leftmost assigning `=', the second line |
| 2800 | is indented two columns beyond that `='. Else it's indented to two |
| 2801 | columns beyond the leftmost solid chunk of non-whitespace characters on |
| 2802 | the base line. |
| 2803 | |
| 2804 | Warning: indent-region should not normally be used! It calls \\[indent-for-tab-command] |
| 2805 | repeatedly, and as explained above, \\[indent-for-tab-command] can't guess the block |
| 2806 | structure you intend. |

| 2813 | %c:py-guess-indent-offset |
| 2814 | |
| 2815 | |
| 2816 | The remaining `indent' functions apply to a region of Python code. They |
| 2817 | assume the block structure (equals indentation, in Python) of the region |
| 2818 | is correct, and alter the indentation in various ways while preserving |
| 2819 | the block structure: |

| 2835 | @MOVING POINT |
| 2836 | |
| 2837 | \\[py-previous-statement]\t move to statement preceding point |
| 2838 | \\[py-next-statement]\t move to statement following point |
| 2839 | \\[py-goto-block-up]\t move up to start of current block |

| 2845 | The first two move to one statement beyond the statement that contains |
| 2846 | point. A numeric prefix argument tells them to move that many |
| 2847 | statements instead. Blank lines, comment lines, and continuation lines |
| 2848 | do not count as `statements' for these commands. So, e.g., you can go |
| 2849 | to the first code statement in a file by entering |
| 2850 | \t\\[beginning-of-buffer]\t to move to the top of the file |
| 2851 | \t\\[py-next-statement]\t to skip over initial comments and blank lines |
| 2852 | Or do `\\[py-previous-statement]' with a huge prefix argument. |

| 2859 | @LITTLE-KNOWN EMACS COMMANDS PARTICULARLY USEFUL IN PYTHON MODE |
| 2860 | |
| 2861 | `\\[indent-new-comment-line]' is handy for entering a multi-line comment. |
| 2862 | |
| 2863 | `\\[set-selective-display]' with a `small' prefix arg is ideally suited for viewing the |
| 2864 | overall class and def structure of a module. |
| 2865 | |
| 2866 | `\\[back-to-indentation]' moves point to a line's first non-blank character. |
| 2867 | |
| 2868 | `\\[indent-relative]' is handy for creating odd indentation. |
| 2869 | |
| 2870 | @OTHER EMACS HINTS |
| 2871 | |
| 2872 | If you don't like the default value of a variable, change its value to |
| 2873 | whatever you do like by putting a `setq' line in your .emacs file. |
| 2874 | E.g., to set the indentation increment to 4, put this line in your |
| 2875 | .emacs: |
| 2876 | \t(setq py-indent-offset 4) |
| 2877 | To see the value of a variable, do `\\[describe-variable]' and enter the variable |
| 2878 | name at the prompt. |
| 2879 | |
| 2880 | When entering a key sequence like `C-c C-n', it is not necessary to |
| 2881 | release the CONTROL key after doing the `C-c' part -- it suffices to |
| 2882 | press the CONTROL key, press and release `c' (while still holding down |
| 2883 | CONTROL), press and release `n' (while still holding down CONTROL), & |
| 2884 | then release CONTROL. |
| 2885 | |
| 2886 | Entering Python mode calls with no arguments the value of the variable |
| 2887 | `python-mode-hook', if that value exists and is not nil; for backward |
| 2888 | compatibility it also tries `py-mode-hook'; see the `Hooks' section of |
| 2889 | the Elisp manual for details. |
| 2890 | |
| 2891 | Obscure: When python-mode is first loaded, it looks for all bindings |
| 2892 | to newline-and-indent in the global keymap, and shadows them with |
| 2893 | local bindings to py-newline-and-indent.")) |
