annotate lib-src/make-docfile.c @ 4742:4cf435fcebbc
Make #'letf not error if handed a #'values form.
lisp/ChangeLog addition:
2009-11-14 Aidan Kehoe <kehoea@parhasard.net>
* cl-macs.el (letf):
Check whether arguments to #'values are bound, and make them
unbound after evaluating BODY; document the limitations of this
macro.
tests/ChangeLog addition:
2009-11-14 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Don't call Known-Bug-Expect-Failure now that the particular letf
bug it tickled is fixed.

| 428 | 26 |
| 27 /* The arguments given to this program are all the C and Lisp source files | |
| 930 | 28 of XEmacs. .elc and .el and .c files are allowed. |
| 29 A .o or .obj file can also be specified; the .c file it was made from is used. | |
| 30 This helps the makefile pass the correct list of files. | |
| 31 | |
| 32 The results, which go to standard output or to a file | |
| 33 specified with -a or -o (-a to append, -o to start from nothing), | |
| 34 are entries containing function or variable names and their documentation. | |
| 35 Each entry starts with a ^_ character. | |
| 36 Then comes F for a function or V for a variable. | |
| 37 Then comes the function or variable name, terminated with a newline. | |
| 38 Then comes the documentation for that function or variable. | |
| 39 | |
| 40 Added 19.15/20.1: `-i site-packages' allow installer to dump extra packages | |
| 41 without modifying Makefiles, etc. | |

| 995 We also look for #@LENGTH CONTENTS^_ at the beginning of the line. | |
| 996 When we find that, we save it for the following defining-form, | |
| 997 and we use that instead of reading a doc string within that defining-form. | |
| 998 | |
| 930 | 999 For defvar, defconst, and fset we skip to the docstring with a kludgy |
| 428 | 1000 formatting convention: all docstrings must appear on the same line as the |
| 930 | 1001 initial open-paren (the one in column zero) and must contain a backslash |
| 1002 and a newline immediately after the initial double-quote. No newlines | |
| 428 | 1003 must appear between the beginning of the form and the first double-quote. |
| 930 | 1004 For defun, defmacro, and autoload, we know how to skip over the |
| 1005 arglist, but the doc string must still have a backslash and newline | |
| 1006 immediately after the double quote. | |
| 1007 The only source files that must follow this convention are preloaded | |
| 1008 uncompiled ones like loaddefs.el and bindings.el; aside | |
| 428 | 1009 from that, it is always the .elc file that we look at, and they are no |
| 1010 problem because byte-compiler output follows this convention. | |
| 1011 The NAME and DOCSTRING are output. | |
| 1012 NAME is preceded by `F' for a function or `V' for a variable. | |
| 1013 An entry is output only if DOCSTRING has \ newline just after the opening " | |
| 3368 | 1014 |
| 1015 Adds the filename a symbol or function was found in before its docstring; | |
| 1016 there's no need for this with the load-history available, but we do it for | |
| 1017 consistency with the C parsing code. | |
