Hi,

is there a way to search "everything" which comes with Emacs?

Example: I do not remember Local Variables section syntax and have to
look it up.  I try various things, fail and end up using web browser.
That is far from ideal.

Today I invested a bit more time and found C-h d command so C-h d "local
variables" and then C-s "local variables:" finds something: one hit
only.  Now I discovered add-file-local-variable function.  But still not
the syntax of the Local Variables section.

Searching info is still a mystery to me.  Is there a way to search
across all info files?

Is there a way to search everything which comes with emacs,
e.g. function names, docstrings, info, NEWS etc?

Cheers,

Tomas

If I understand your needs correctly, 'apropos' will give you some of
what you want. However it won't search the info files, news, etc.

But actually for learning how to do something, web search really is
the best option.

There are ways to search everything that comes with Emacs. There is
just no united way for everything.

The menu item HELP - DESCRIBE contains many pointers. Then you have
plethora of M-x apropos* and M-x describe* functions. Then you have
the manual with {C-h r} and {C-h i} for other manuals.

Try here:

(info "(emacs) Specifying File Variables")
(info "(emacs) Safe File Variables")

M-x info-apropos searches through many info files.

> e.g. function names, docstrings, info, NEWS etc?

Obviously yes, there are various methods. But I do not think there is
one unified method to search everything together. I also do not find
it necessary.

I also recommend using {M-x package-install RET hyperbole RET} as it
will help with quicker jumping from function to function. For example
when I am on some definition of a function such as (dolist (a b)) if I
press M-RET on "dolist" then it brings me quickly to function definition in other window where I can see:

(defmacro dolist (spec &rest body)
  "Loop over a list.
Evaluate BODY with VAR bound to each car from LIST, in turn.
...

For specific stuff the web search provides solutions.

For general stuff people shall start with:

1. TUTORIAL under Help - Emacs Tutorial or {C-h t}

2. The Emacs Editor manual: (info "(emacs) Top")

3. An Introduction to Programming in Emacs Lisp: (info "(eintr) Top")

4. Emacs Lisp manual: (info "(elisp) Top")

5. Using the menu item Help.

To search all info files use {M-x info-apropos RET} or click within 

If one wants to index various files on system then person can use
desktop indexing software. That will not nicely help with Emacs
variables and functions. But it could help by at least locating where
some information exists.

First run info emacs, next hit the slash key and key in a search string. 
That's from the command line.

Thanks, that seems useful. Did you try 'C-u C-h d'? Or set the variable
apropos-do-all to non-nil? That should yeild a more extensive search.

Maybe the stuff actually found typically is specific, but the search on
the web is so general it must be hard to compete with.

It has happened to me a number of times I search the web on some Emacs
question, find links to the Emacs manual wich provide the answer and
only by then understand I would have found it by a direct search in the
manual.

But there must be nothing wrong with this combination of searching the
web and searching Emacs. Sometimes even if something is described in
detail in the manual, it is faster or more convenient to see some
user-written example on the web.

I have been using emacs for decades and was unaware of this command.
Perhaps help-for-help-internal could be improved to make it more discoverable.
Today we have:

A possible improvement might be:

Menus are a good way to discover things.

`Help > Search Documentation' has these menu items:

 Emacs Terminology
 Look Up Subject in User Manual
 Look Up Subject in Elisp Manual
 Look Up Key in User Manual...           C-h K
 Look Up Command in User Manual...       C-h F
 _____________________________________________
 Find Commands By Name...                C-h a
 Find Options By Name...
 Find Options By Value...
 Find Any Object By Name...
 Search Documentation Strings...         C-h d

Notice the last one.

IMO it's too bad that many people have come to get
the idea that using menus is for sissies.

I think this is especially true of developers, and
of Emacs users generally.  It's misguided, IMHO.

Using menus is for anyone who wishes and/or likes to do so,
and as mentioned elsewhere, they do have the great advantage
of allowing for learning by discovery (this is especially true
if you use Gnus).

I don't use them myself, not because of a fear of being
labeled, and certainly not because I already know everything
(I prove daily that I'm forever learning). I don't use menus
because for me they get in the way by taking up screen space,
being distracting, and generally requiring reaching for the
mouse. But my use case is not necessarily anyone else's.

Is this not what all the work on completion / narrowing frameworks

I rarely use them as well, but I do find them handy every once in a while.

I use (menu-bar-mode -1) to solve this problem.
It's still available on `C-mouse-3` so nothing's lost.

Since I use them rarely, I usually don't mind using the mouse in those
rare cases.  But there's probably some way to make it pop up in response
to a keyboard event (and you can definitely navigate it with the mouse).

I don't ever use the mouse but other than that I agree 100% :)

But ... this is a mere interface issue/detail and shouldn't be
a dispute, TEHO.

Rather, what _are_ the best ways of "fining stuff", in general
I mean? Is there a unified function to look everywhere and to
give an output with hints/links where to look next, an output
that may point to emacs(1), tutorials, manuals, the Wiki,
maybe even sites like the Emacs SX, furthermore docstrings,
FAQs, all you can think of and all that exists? If so,
I didn't see it! (Well, if it exists, maybe I could use it to
find it, even!)

What I can think of ... what I use ... that doesn't do that
but are still very useful ... are

  `apropos'
  `apropos-command'
  `apropos-value'

I think John Yates makes a good suggestion.

Alternatively, info-apropos could be associated with C-h C-i by
default.  As far as I can tell there is nothing that uses that binding
in vanilla Emacs.

You sound sure of yourself.  Perhaps you thought
I meant the developers _of Emacs_?  I didn't.

I meant that I'm guessing that people who do a
lot of software development are maybe less likely
to use menus (and a mouse) - as opposed to your
average computer user.

This sounds like The Computer Chronicles in 1985...

Maybe back then "real programmers" didn't use menus but then
also came the whole desktop paradigm with Apple (Finder) and
Windows so by now there are many, many skilled programmers
that use menus all the time and they don't even know other
skilled programmers have the habit, and perhaps takes some
small pride in, not using menus!

It is just a matter of style ... doesn't say anything
about skill.

Like they say, you have to be a bit modest, because somewhere
on the planet there is a coder who is more skilled than
you. Ha.

My suggestion to repurpose 'C-h I' was to conform to the pattern
in that table of binding wherein an uppercase letter implements a
deeper, more verbose version of its lowercase counterpart.  Such
patterns facilitate (my) memorization.

One might hope that you are right.  My experience
suggests otherwise.

Anecdotally based on comments in Emacs mailing
lists, the proportion of Emacs users who turn off
the menu-bar seems quite large.  Likewise, those
who eschew use of a mouse (in Emacs at least).

Also based on comments I see in mailing lists, I
think that many/most Emacs users are programmers.
___

To be clear, _I_ do use the menus.  The point of
my post was to _recommend_ them, for discovery.

The Help command that OP found to be so helpful
in this thread, and that was thought to be so
hard to discover, is right there in the `Help'
menu, hiding in plain sight.  But you have to
have a reflex to look under `Help', to find it.

FWIW: Not only do I use menus, but I go to great
lengths to ensure my libraries have good menus.

And I wrote library La Carte, which lets you
navigate Emacs menus using the keyboard.

Especially if combined with powerful incremental
matching, you can easily discover and access
menu stuff at all levels, directly - no need to
drill down layer by layer (though that's possible
too, as well as going back up).

Yup.  I bind it to `lacarte-execute-menu-command'.

It included the qualification "I think".  And "IMO".
And "especially".  And "generally".  And "IMHO".

As usual, you want to quibble.  (Sue me.)

After your first remark I clarified what I meant.

And yes, it's my impression that "many people have
come to get" the idea that many menus aren't worth
bothering with - in particular, I think, many
programmers.  And perhaps many Emacs users.

And one reason for that might be that sometimes
3rd-party Emacs libraries don't put a lot of
emphasis on providing good menu support.  Menus,
like doc, can often take back seat.  Programmers
like to code. ;-)

Have I added enough "perhaps", "might", "maybe",
"I think", "often", "sometimes" etc. for you?
(If not...)

What I say is only what I think.  YMMV.  I don't
preface everything I say with "It's my impression
that...".  (Do you?)
___

Message: Menus have more to offer than (I think)
many people realize.  Good menus, especially.

(OP here.)

Drew, Are you saying that the help menu contains
items that are not listed by C-h C-h?  That, to me,
would be very surprising.

I am not opposed to using the mouse.  I avoid
menus because they present such a jarring UI
discontinuity.  Your LaCarte sounds intriguing.
Does interface with completing-read (i.e. can I
use it in conjunction with Selectrum and friends)?

The thread OP is actually Tomas Hlavaty.  But yes,
you're the one I meant, by OP.  You mentioned that
you've been using Emacs for decades but you were
unaware of that command.  There's so much we aren't
aware of - all of us.  (That particular command is
about as old as Emacs, BTW.)

> Drew, Are you saying that the help menu contains
> items that are not listed by C-h C-h?  That, to me,
> would be very surprising.

No, I didn't say that or mean to suggest it.  Without
checking, I'd assume, like you, that the `Help' menu
covers all of what `C-h C-h' covers.

My point was only about discoverability.  `C-h C-h'
is a fine way to discover help commands.  So is the
`Help' menu'.  My contribution was to second that
last point, which was first stated in the thread by
Jean Louis.

Specifically, I wanted to point out how helpful the
`Help' menu is, and that the command in question is
there, with the name `Search Documentation Strings'.

And yes, it's also listed with `C-h C-h':

  MORE ADVANCED HELP
  ------------------
  d: Shows Emacs functions and variables whose
     doc matches a regexp.

One can argue about the most helpful words used
to describe this, in terms of discoverability.
Menu `Help' talks about "searching" doc strings.
`C-h C-h' talks about "matching" doc.  And the
command name has the components `apropos' and 
`documentation'.  For users who know about
apropos,  "apropos" helps; for others, it might
not help so much.

> I am not opposed to using the mouse.  I avoid

> discontinuity.

Menus are one way to access commands.  Like the
other ways, they have their plusses and minuses.

For help, at least, we have `C-h C-h', which
_groups help commands_.

We don't have much otherwise (e.g. to help
discoverability), when it comes to _grouping_
related commands.  We can have related keys
(e.g. same prefix key or similar key mnemonics).
We have related command names (with some degree
of naming convention).  And we have apropos
(`C-h a' etc.).

Those all help group commands somewhat, and so
help with discoverability.  But each has its
weaknesses in that regard.

If you have a good completion system then you can
also find commands, variables, etc. by their name components etc., or even by doc matches - similar
to `apropos-documentation.  (I do that all the
time, using Icicles progressive completion.)

But menus too can aid discoverability, using
hierarchy and grouping (with named groups).

> Your LaCarte sounds intriguing.
> Does interface with completing-read (i.e. can I
> use it in conjunction with Selectrum and friends)?

Yes, you should be able to use it with any
completion system.  Yes, it uses `completing-read'.

Yeah, in a consumer-oriented, very limited piece of software,
it is always a good habit to first check out the settings
(and/or menus) to see what things are there.

But here - no fishing expeditions, thank you.

Well, except for real ones. Relaxing, fun, and you always
learn something new even from very modest tours.

Maybe in the hard-core Unix and Emacs community there is
a tilt towards that but if you think you are alone think
again, just check out Eclipse, all the Microsoft IDEs ...
there, menus are a/the fundamental building block of
the interface.

And while it is possible to have menus in Emacs, here, the
corresponding building block is not menus but shortcuts.
So obviously people here tend to not use menus, or use them
much less...

I think shortcuts are better, faster, they don't involve
a mouse, they are less disruptive visually and imply less eye
strain as there is no alternative to spot and pick, so all in
all, they are much more ergonomic. (Especially good shortcuts! ;))

But I suppose you are right, for the purpose of, with your
word, discoverability, menus are better.

But can't you do the same discovery travel with shortcuts,
with `C-h m' or `describe-mode'?

If I would really need to search all Emacs files, I would do the
following: Download the source code repository and execute =grep=
there but in all this time I've been using Emacs, I've never felt the
need to do this.

Apparently, what you were trying to find was a section in the Emacs
info manual and you knew some keywords but wasn't able to find the
Info heading. What I would do is the following:

1. Visit the =Emacs= info file. That is, execute =info-emacs-manual=
   (or press =C-h r=)
2. Execute =Info-toc= (or press =T=)
3. Execute =occur= (or press =M-s o=) while being in the =Table of
   Contents=.
4. Search the keywords I want to know about. In this scenario, they
   would be: =local variables=.

If no occurrence were found, I would repeat the same process with the
=Elisp= info manual.

If you want to actually search a given regexp in all info manuals, you
can try the following command. I would call this the brute-force
method. If you haven't set the =$INFOPATH= environmental variable,
then just use =/usr/share/info= as your =$path_info=.

#+begin_src dash
path_info="$(printf "%s" "$INFOPATH" | tr ":" "\n")"

pattern="emacs"
flags="--color"

find $path_info \
  -type f \( \
    ! \( -name '*.png' -o -name '*.gz' \) -exec grep "$flags" -- "$pattern"
{} + \
    -o -name '*.gz' -exec zgrep "$flags" -- "$pattern" {} + \
  \)
#+end_src

Or maybe the people that do so are just very vociferous about it?  

I have kept the menu bar.  Ever since I learned that C-h k followed by selecting a menu item reveals the menu item's underpinnings, the menus became a learning tool and not a WYSIAYG thing.

Yes, the point was about discovery.

It's not about using menus versus using keyboard keys to invoke commands regularly.

Yeah, but still, if it is about discovery there should be
a solution that is focused on that and only that, that has
nothing to do with either menus or shortcuts or anything else
unrelated...

No, you can't.  (Whatever's not the same is
different - has relative (dis)advantages.)

1. `describe-mode' is limited.  It's limited to
whatever someone wrote for it for the given mode.

2. Menu items generally describe/name commands a
bit differently from their command names.  I cited
the example for the case in question (`C-h d').

And menus group related commands, in a hierachy.
The names of the ancestors and siblings in the
hierarchy also help with discovery.

3. Wrt matching against menu names (items and
their ancestor menus): If you use something like
La Carte together with completion that allows
substring or regexp matching, and progressive
completion, then you can directly match component
bits of a menu item looked at as an absolute name,
i.e., including its entire path from the root.

That lets you discover it based on any/all of its
ancestors, as well as the item name, AND go to it
directly, in one go.

4. All of these are helpful, including for
discovery, and each offers a difference access
approach or entry point:

* key sequence (e.g. mnemonic, similar to keys
  for related behavior)
* command name (e.g. name components that say
  different things about what it means/does
* menu item name
* full menu item name, i.e., including its "path"

Maybe so.  But I've followed not only the mailing lists but also various Emacs-help websites (e.g. EmacsWiki, emacs.StackExchange, Reddit), and that's my impression from 35 years of that.  (Well, maybe 30, since menus weren't there at the beginning, IIRC; and maybe 20 or less for the websites).

Definitely.

That, BTW, is also something I wish we had a good/better way of making better known.  It's not necessarily obvious to users that they can use `C-h k' with mouse actions, including use of menus.

Regardless of whatever side-effects menus may have in this or
any other direction, their purpose is for the user to invoke
commands, and this happens in a certain way.

The problem remains that if one doesn't like that certain way,
the discoverability side-effect won't help. One will still not
like it and probably not use it.

Instead, if we were to go discover stuff, we should have
a dedicated `discovery-mode' with that and only that purpose,
so that everyone, menu lovers and haters alike (because that
has nothing to do with it), so that everyone can discover
Emacs and then invoke the newfound commands in... you guessed
it... any way they like!

menus vs shortcuts - fine discussion

menus vs shortcuts with respect to "discoverability" - DNC

Thanks Tomas, this helped!

- There is an example in no-byte-compile directly shown in the results.

- I discovered ps-begin-cut-regexp and ps-end-cut-regexp related to the
  thing I was doing.

People suggested many ways of finding different things.  I can not
remember them all and know in each context which one to choose.

grep through emacs sources seems to give me fastest way of finding
stuff.  It is not perfect but I don't have to remember anything.

   (grep "grep -r -nH --color -i -e 'local variables:' ~/mr/emacs")

or

   (grep "rg -nH --no-heading -i 'local variables:' ~/mr/emacs")

This topic also led me to discover eev, which I find amazing.

Thanks to all for suggestions!

Hey! Thanks for the mention to eev!!! =)

I just realized that there was something missing in eev, and I fixed
that and commited the fix to the git repository... here is a quick
explanation. When eev-mode is active the key sequence `M-h M-h' runs
`find-here-links', that generates a temporary buffer with "links to
here", as explained in:

  http://angg.twu.net/eev-intros/find-here-links-intro.html
  http://angg.twu.net/2020-find-here-links.html

Now, after the fix, typing `M-h M-h' on a grep buffer generates a
temporary buffer whose last lines are something like this:

  (let ((default-directory "~/bigsrc/emacs27/lisp/"))
    (grep "grep --color -niH --null -e 'local variables:' *.el")
    )

this a (3-line) elisp hyperlink that doesn't need eev to run, and that
should make sense to non-eev users... and they should find the
directory part trivial to adapt.

  Cheers, thanks, and apologies for the shameless plug =),

Thank you.

I get this:

# See: 
# (find-eev-quick-intro "4.1. `find-here-links'")
# (find-emacs-keys-intro "1. Basic keys (eev)" "M-h M-h")

(let ((default-directory "~/git/notes/"))
  (grep nil)
  )

Maybe evaluating grep form does not add it to grep-history?

It doesn't! See:

  (find-efunction 'grep)
  (find-efunction 'grep "read-shell-command")
  (find-efunction 'read-shell-command)
  (find-efunction 'read-shell-command "read-from-minibuffer")
  (find-efunctiondescr 'read-from-minibuffer)
  (find-efunctiondescr 'read-from-minibuffer "add-to-history")

To be honest I've never transferred grep arguments from a sexp
hyperlink to the M-x grep prompt, only the reverse... I find much
easier to edit the arguments in a "real"/"normal" Emacs buffer than in
the minibuffer - and, btw, I almost always duplicate the sexp hyperlink
with M-h M-2 before editing it, and this lets me have my recent
grep-history all in sight, in an format like this:

  (find-ghcgrep "grep --color -nRH --null -e  foldr   libraries/base/*")
  (find-ghcgrep "grep --color -nRH --null -e 'foldr ' libraries/base/*")

[[]], E. =)

Interesting, thanks for the pointers.

I found that in addition to grep-history there is also
grep-find-history.

Maybe it should not take the argument from grep-history but from the 4th
line of the grep buffer.

> To be honest I've never transferred grep arguments from a sexp

I did not transfer anything.  I evaluated (grep "...") and then pressed
M-h M-h and then I got (grep nil) in the links buffer.

Interesting, I'll try that.

M-h M-2 is not bound in (eev-beginner) so I might be getting advanced:-)

I think a way of searching all those things would be useful.  As others
have mentioned there are separate ways of searching most of them.  I
think "info-apropos" is the most useful for your wishes.

Another possibility that people haven't mentioned is to build Emacs from
source then to load the tags-table and search that.

However, I still think that info-apropos is best.  Things like grep or
the Emacs source can bring too many hits to be useful.

BR,
Robert Thorpe

info-apropos looks interesting.

I just have to be careful what do I search for.  For example

   (info-apropos "local variables:")
   (info-apropos "Local Variables:")

gives: No matches found.

   (info-apropos "local variables")

Gives good links.

But it is much slower than grep.

That is more complicated than grep.

It would be good to have a cross platform general search engine that
would find any similar terms and also work with various languages.
But we do not have such.

Sometimes avoiding plurals may find more results. Of course removing
any punctuation is advised, but the underlying search engine should
be doing that work.

I just guess that excess spaces should be removed by the underlying
program. But I don't think that 

(info-apropos "local  variables")
works same as 
(info-apropos "local variables")
