Subject: |
25.1; Several documentation problems |
|
Date: |
Sun, 6 Nov 2016 19:14:52 -0200 |
I am sorry for having taken this long to report these problems as I
said I would.
1) outline-hide-sublevels and outline-hide-other\\
The docstrings and the manual should say that each of these commands reveals
everything it does not actively hide. For example, outline-hide-sublevels
reveals the top N levels of headlines and the top headless body, and all else
is hidden. So if N is 2 and some level 1 tree was folded, its children will
be actively revealed.
Also, please document that, for outline-hide-sublevels, N defaults to the
level of the current headline.
Finally, perhaps the manual should mention that hide-sublevels, hide-other
and some other commands are actually deprecated aliases.
2) [[info:emacs#Outline Visibility]] informs that hide-body does not
hide the top
headless body. This information should also be in the docstring. Also,
maybe the manual should inform that "hide-body" is a deprecated alias for
"outline-hide-body".
3) Tutorial
1. In section "* AUTO SAVE", the tutorial mentions "recover-file" where
"recover-this-file" would be better and perhaps recover-session would be
best.
2. Why does section "* MULTIPLE FRAMES" use "M-x make-frame" and
"M-x delete-frame" instead of "C-x 5 2" and "C-x 5 0" respectively?
3. In section "* GETTING MORE HELP":
1)
#+BEGIN_QUOTE
Multi-character commands such as C-x C-s and (if you have no META or
EDIT or ALT key) <ESC>v are also allowed after C-h c.
#+END_QUOTE
The way that is written, some user might think that "C-h c <ESC>v" only
works if the terminal lacks a META or EDIT or Alt key. I suggest
replacing the parenthesized text by "(alternative to M-v)", positioned
just after "<ESC>v".
2)
#+BEGIN_QUOTE
C-h a Command Apropos. Type in a keyword and Emacs will list all the
commands whose names contain that keyword. These commands can all be
invoked with META-x. For some commands, Command Apropos will also list
a one or two character sequence which runs the same command.
#+END_QUOTE
In the last sentence please replace "one or two" → "short", as some
commands (like find-file-other-frame) have character sequences of 3-4
chars.
3)
#+BEGIN_QUOTE
C-h i Read included Manuals (a.k.a. Info). This command puts you into a
special buffer called `*info*' where you can read manuals for the
packages installed on your system. Type m emacs <Return> to read the
Emacs manual. If you have never before used Info, type ? and Emacs
will take you on a guided tour of Info mode facilities.
#+END_QUOTE
The guided tour is provided by "h". "?" is also useful, but provides
Info-summary, not the tutorial. Complete beginners need "h" first,
then "?" for a quick reminder each time they forget a keybinding.
4) [[info:emacs#Exiting]] says C-z is bound to suspend-emacs. It is
actually bound
to suspend-frame. Only several paragraphs below does the manual report the
correct information. Please correct the first mention of "C-z".
5) [[info:emacs#Mode Line]] omits the "@" of emacsclient frames.
6) [[info:emacs#Completion Styles]] on partial-completion
Says that
#+BEGIN_QUOTE
Furthermore, a ‘*’ in the minibuffer text is treated as a “wildcard”—it
matches any character at the corresponding position in the completion
alternative.
#+END_QUOTE
Actually it matches any /string/ at the corresponding position.
7) "list-command-history" docstring is confusing. It says "List history of
commands typed to minibuffer." This does not clearly explain that the
command lists the history of commands that /used/ the minibuffer, including
those that were invoked by keys.
8) [[info:emacs#Yes or No Prompts]]
1. Swaps "M-v" with "C-v".
2. In the last paragraph it says:
#+BEGIN_QUOTE
use the history commands ‘M-p’ and ‘M-f’, etc.
#+END_QUOTE
It probably meant M-n instead of M-f.
9) [[info:emacs#Help Mode]] says:
#+BEGIN_QUOTE
While retracing your steps, you can go forward by using ‘C-c C-b’
(‘help-go-forward’).
#+END_QUOTE
"help-go-forward" is not "C-c C-b".
Also, the section omits the handy single-letter aliases: "l" ("C-c C-b"), "r"
("C-c C-f").
10) [[info:emacs#Misc Help]]: In the paragraph for describe-mode, please mention
that it shows the key bindings, which is very useful.
11) "set-mark-command" docstring omits the behavior of activating the mark.
Also it says:
#+BEGIN_QUOTE
Also push the old mark on global mark ring, if the previous mark was set
in another buffer.
#+END_QUOTE
Actually, AFAICT it pushes to the global mark ring /the mark just set/.
12) "C-[" for "<ESC>" and "C-i" for "<tab>"\\
The manual and probably also the tutorial should mention at the beginning
that C-[ is an alias for <ESC>. It is very useful because C-[ is faster to
type. Sometimes the difference is big, such as in "C-x ESC ESC" → "C-x C-[
C-[". In fact it is sometimes faster to type C-[ * than M-*.
C-i as an alias for TAB is also very useful. For example, to bring an Org
buffer to startup visibility, "C-u C-u C-i" is faster to type than
"C-u C-u <tab>".
13) [[info:elisp#Coding Conventions]]
#+BEGIN_QUOTE
• If loading the file adds functions to hooks, define a function
‘FEATURE-unload-hook’, where FEATURE is the name of the feature the package
provides, and make it undo any such changes. Using ‘unload-feature’ to
unload the file will run this function.
#+END_QUOTE
info:elisp#Unloading, however, mentions /FEATURE-unload-function/ instead of
/FEATURE-unload-hook/.
14) [[info:emacs#Other Repeating Search]]: In my test, "M-s o" does
not "Run ‘occur’
using the search string of the last incremental string search." Instead it
calls "occur" and asks for the pattern. The pattern can then be yanked with
"M-n".
15) [[info:emacs#Dynamic Abbrevs]] imprecision – it says:
#+BEGIN_QUOTE
After scanning the current buffer, ‘M-/’ normally searches other buffers,
unless you have set ‘dabbrev-check-all-buffers’ to ‘nil’.
#+END_QUOTE
Actually, according to the docstrings of "dabbrev-check-all-buffers" and
"dabbrev-check-other-buffers", the "unless…" part is imprecise. I suggest
rewriting to
#+BEGIN_QUOTE
After scanning the current buffer, ‘M-/’ normally searches other buffers.
This can be customized via the options "dabbrev-check-other-buffers" and
"dabbrev-check-all-buffers".
#+END_QUOTE
Also, the docstring of "dabbrev-expand" should mention these two options.
And it should fully describe the behavior when both options are left at
their defaults. Currently it does not say what happens by default if no
suitable preceding word is found in the buffers accepted by the function
pointed out by dabbrev-friend-buffer-function.

Maybe I'm missing something, but what does "Hide everything but the
top LEVELS levels of headers" mean, if not that all the headers of
those levels are revealed?

Once again, I'm at a loss. The doc string says
Hide everything except current body and parent and top-level headings.
IOW, it hides everything, leaving the current body revealed. How else
can this phrase be interpreted?

To have occur use the last search string, you need to type "M-n" at
the prompt. I've now clarified this in the manual.

That is already in the doc string.
Thanks.
