annotate lib-src/make-docfile.c @ 5076:d555581e3cba
fix issues with display of argument docstrings
-------------------- ChangeLog entries follow: --------------------
lib-src/ChangeLog addition:
2010-02-25 Ben Wing <ben@xemacs.org>
* make-docfile.c:
* make-docfile.c (write_c_args):
Convert newlines to spaces so that argument lists are always on one
line, because that's what function-documentation-1 expects.
lisp/ChangeLog addition:
c2010-02-25 Ben Wing <ben@xemacs.org>
* autoload.el (make-autoload):
Call cl-function-arglist with one arg.
* cl-macs.el (cl-function-arglist):
* cl-macs.el (cl-transform-lambda):
Make cl-function-arglist take only one arg, the arglist; no
function name passed. Also make sure to print () instead of nil
when empty arglist, or function-documentation-1 won't recognize
the arguments: line.
* help.el (function-arglist): If empty arg, don't display extra
space after function name.

| 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. | |

| 1008 | |
| 930 | 1009 For defvar, defconst, and fset we skip to the docstring with a kludgy |
| 428 | 1010 formatting convention: all docstrings must appear on the same line as the |
| 930 | 1011 initial open-paren (the one in column zero) and must contain a backslash |
| 1012 and a newline immediately after the initial double-quote. No newlines | |
| 428 | 1013 must appear between the beginning of the form and the first double-quote. |
| 930 | 1014 For defun, defmacro, and autoload, we know how to skip over the |
| 1015 arglist, but the doc string must still have a backslash and newline | |
| 1016 immediately after the double quote. | |
| 1017 The only source files that must follow this convention are preloaded | |
| 1018 uncompiled ones like loaddefs.el and bindings.el; aside | |
| 428 | 1019 from that, it is always the .elc file that we look at, and they are no |
| 1020 problem because byte-compiler output follows this convention. | |
| 1021 The NAME and DOCSTRING are output. | |
| 1022 NAME is preceded by `F' for a function or `V' for a variable. | |
| 1023 An entry is output only if DOCSTRING has \ newline just after the opening " | |
| 3368 | 1024 |
| 1025 Adds the filename a symbol or function was found in before its docstring; | |
| 1026 there's no need for this with the load-history available, but we do it for | |
| 1027 consistency with the C parsing code. | |
