indentation, setting variables, commands, and M-x

indentation, setting variables, commands, and M-x

[John M. Gabriele]

Hi, I've just started to learn emacs, and would like to try
using it as my primary editor/IDE, but first need to get a few
things set up. For one thing, the indentation issue.

I'd like to only get spaces in my files, 4 for each level of
indentation, and also have the autoindent work (filling in
spaces as necessary). That is, when I hit the TAB key, I want
to get enough spaces to the next indent-level, filling in
spaces along the way.

I just read here: http://www.emacswiki.org/cgi-bin/wiki/NoTabs
that I can add this

     (setq-default indent-tabs-mode nil)

to my .emacs file (which I haven't yet created). That page says
I can "customize the indent-tabs-mode variable". What does that
mean exactly? How do I go about "customizing" it?

I'm also curious: what's the translation between adding the
above line to my .emacs, and typing something in while editing
(presumably "M-x something")? That is, if someone tells me a
line to add to my .emacs file, how can I figure out how to do
the same thing from within the editor while editing?

Continuing with the indentation issue, I read here:
http://www.emacswiki.org/cgi-bin/wiki/IndentationBasics that
there's a number of "variables" I can set. I see "tab-width"
there. Yay! That looks like what I want. :) But, again, how
do I "set a variable" for emacs (both in my .emacs file,
and live, while editing)?

Regarding the autoindent, Reading here:
http://www.emacswiki.org/cgi-bin/wiki/AutoIndentation it
sounds like autoindent isn't something that comes free, but
instead, to get it, you have to put a one-liner into your
.emacs file. Seems like maybe something that should be
default behaviour, no?

Thanks!

Customizing a variable means do exactly what you are about to do: add
a line to your .emacs that sets the variable to some value.

The line above is actually Lisp code.  If you want to avoid adding
Lisp to your .emacs yourself, or if some variable needs tricky
customization that your Lisp is not good enough to master, try the
"M-x customize" interface, which will present a buffer with clickable
buttons and then write the necessary Lisp for you.  For example, "M-x
customize-variable RET indent-tabs-mode RET" will do that for the
variable you want.

The easiest way to do that is type the necessary stuff into your
.emacs, and then evaluate it.  For a single parenthesized expression,
go to the closing right paren and type "C-x C-e".  For several
expressions, do this for each expression in turn.

It isn't, most probably, not if you wish to code in C/C++.  For those
languages, the indentation system is very elaborate, so the way to
customize it is to use the interactive procedure explained in the CC
Mode manual.  Type "C-h i m CC mode RET", then "g Interactive RET",
and you will be looking at that explanation.  (This invokes the Info
mode that is a mode to read on-line manuals.  If you aren't yet
familiar with Info, take a few minutes to do so, since a complex
system such as Emacs is impossible to use efficiently without knowing
how to take advantage of its elaborate documentation.)

See above.  In addition, for a single variable with a simple value,
typing "M-x set-variable RET indent-tabs-mode RET nil RET" will do
what you want.

This is an absolutely standard setup for Emacs.  You're in good company!
Actually, TAB doesn't indent to the next indent-level, it indents to the
_correct_ level, as determined by the syntax of the source code.[*]  So
if you pressed TAB on the following line:

    if (foo)
    {
        bar () ;
                 baz () ;    <===== press TAB on this line

, you'd get this:

    if (foo)
    {
        bar () ;
        baz () ;


[*] If you really, really, really want TAB to indent to the _next_ level,
you can configure this.

A bit of background: your .emacs, your configuration file, is "just" a
file, and you can edit it like any other file.  The best way to create it
is with C-x C-f <ret> ~/.emacs <ret>.

However, editing .emacs means knowing at least a minimal amount of Lisp.
The "customization" facility is a form-based point-and-click interface
which changes your .emacs without you having to grok Lisp.

To "customize the indent-tabs-mode variable", you'd do this:  M-x
customize-variable <ret> indent-tabs-mode <ret>.  You then change the
fields on the form, finally clicking on <save-for-future-sessions>.  This
writes something like "(setq-default indent-tabs-mode t)" into your
.emacs file, creating the file if necessary.

Note that you might find the customization form not as simple and
straightforward as you might expect.

If you execute some Lisp whilst editing, its effect won't be saved for
future sessions.  The simplest way to execute lisp is with M-: (that's
"meta-colon"; use "<escape> :" if your keyboard can't do M-:).

Whilst editing: either M-x set-variable, or M-: (setq tab-width 4), or
use customize-variable.  That's a matter of personal taste.  For your
.emacs, either customize-variable, or write (setq-default tab-width 4)
directly into the file.

There is an extra complication with tab-width: it is a "buffer-local"
variable, i.e. when you set it, the setting only has effect in the
current buffer.  To change the default, use `setq-default'.  To change
the value in the current buffer, use `setq'.

Autoindentation is enabled by default for programming modes like C Mode
and Emacs Lisp Mode.

GNU Emacs allows you to (almost) simultaneously edit a large number  
of files or files not yet saved as files in modified buffers. That "M- 
x something" means that you invoke a command, a Lisp function for  
interactive use (there are also non-interactive Lisp functions). To  
stop editing one file (buffer) you just change to another buffer  
(whose contents comes or comes not from an existing file) or you  
create a new buffer by opening a file, .emacs for example. You can  
decide to save what was achieved in the original buffer (although GNU  
Emacs automatically saves the work in progress and keeps an almost  
indefinite amount of undo's).

Any change you do to .emacs does *not* change the way the running GNU  
Emacs behaves. It just prepares for the next one. If you want your  
change apply for the running one, too, you would need to evaluate the  
Lisp code.

See also my next answer.

You can look up a 'variable' with the command C-h v. In the mini- 
buffer you'll be prompted for a name, but you can try (command)  
completion, pressing TAB. Then a *Completions* buffer opens showing  
all variables available. You can scroll through these buffer by  
pressing SPACE repeatedly and then 'pick' a name, or at the prompt  
you can start writing the variable name's beginning and expand this  
string with TAB until it starts to become ambiguous, i.e. there is  
more than one choice to complete the name. If you see the variable  
printed somewhere you can position the cursor on it and invoke C-h v.

Once the *Help* buffer is created which explains the variable, you  
often see a hint that you can customise this variable. Follow the  
hyper link and a *Customization* buffer opens. You can just try the  
new setting (it changes Emacs' behaviour at run time), and you can  
save this setting in .emacs, at once or later.

Autoindent works in kind of 'qualified' modes. In text mode you  
indent in such a way that words in the next line start in the same  
column as the words in the line above, columns of words are built.  
The one-liners can modify the way autoindentation works in the many  
modes.

To find the default behaviour of modes just stay without a .emacs  
file or launch GNU Emacs with the option -q, which makes it not to  
read .emacs.

RE: indentation, setting variables, commands, and M-x

[Drew Adams]

    Hi, I've just started to learn emacs, and would like to try
    using it as my primary editor/IDE, but first need to get a few
    things set up. For one thing, the indentation issue.

Emacs Wiki is a great source for information, but another source, which is
generally more complete, more official, and more accessible is the Emacs
manual. Just use `C-h i' (Control-h i) in Emacs, click "Emacs" (for the
Emacs manual), and then search for what you want.

The manual is in Info mode. To get information on the current mode (whatever
it is) at any time in Emacs, use `C-h m' (all Emacs help commands start with
`C-h', and `C-h ?' gives you the list).

In this case, you want to search the manual for "indent" or "indentation".
Looking through the explanation of Info mode (from `C-h m'), you'll see that
`i' looks up a topic in the index, and `s' searches the manual for a term.
Using either `i indentation' or `s indentation' will soon get you to the
part of the manual that answers most of your questions (`i indentation' will
take you there directly, because there is an "indentation" index entry).

Emacs is a self-documenting system - perhaps the first such and still
probably the best. Spend some time learning the help commands first (`C-h
?'), then explore the manual a bit. You'll soon be hooked.

I believe you meant to say "C-x C-f ~/.emacs RET".  You got an extra
return in there (which puts you into dired mode and then you flag all
backup files...).

I few things I didn't understand from your resplies:

Do that right in the text/buffer that I'm editing?

Thanks for the clarification. :)

Ah. The major programming language modes (am I saying that right?)
are more sophisticated than I'd thought.

What's the difference between a "mode" and a "variable"?
indent-tabs-mode looks like it could be both...

Nice. Didn't know about C-h v.

> Autoindent works in kind of 'qualified' modes.

Hm. Well, It doesn't seem to be working for me. I tried
creating a .java file and a .py file, and editing both, neither
one autoindents. It could be that I need to install some
extra Python mode? But that doesn't explain why the java
one wouldn't work...

BTW, here's my first attempt at a ~/.emacs file:

(setq-default indent-tabs-mode nil)
(setq-default tab-width 4)
(setq-default transient-mark-mode 1)
(setq-default font-lock-mode 1)

Does that look right?

The transient-mark-mode works, but the font-lock-mode
doesn't seem to work... Hm. If I open a .java file, syntax
highlighting only works only if I do:
M-x font-lock-mode
M-x font-lock-mode
(disable, then re-enable). Weird... (Actually, please
let me know if that's the topic of a different thread.)

Thanks,
---John

It's a slight pain when Emacs uses vocabulary that is hard to guess,
e.g., fill for line-wrapping, and font-lock for syntax coloring. In
these situations, s and i aren't much good.

Those issues are slowly sorting themselves out for me, though.

I'm finally learning emacs because the functional programming world
seems to rely on it for so many of their IDEs. I'm on a strict regimen
of NO VIM until I'm finally confortable with it. Learning vim first
was just a historical accident, after all.

Ok, I hit C-h m,and it waits for me to give a menu name. How do I get
to a
place where I can hit 'i' to look up a topic in the "index"? I see that
's' asks
me for a regex to search for, and it searches down the page, from the
current cursor location to find it. Is there a separate index page for
each
node? Or maybe only some nodes?

You need to do a bit more. font-lock-mode is a bit shy  
(conservative). I have in my .emacs:

	(cond ((fboundp 'global-font-lock-mode)
	   ;; Turn on font-lock in all modes that support it
	   (setq global-font-lock-mode t)
	;   (setq font-lock-multiline 'undecided')
	   (setq jit-lock-stealth-verbose t)
	   (setq jit-lock-mode t)
	;   (setq jit-lock-stealth-load 80)
	   ;; Maximum colors

That's why there's the Glossary section in the manual.  You should
look there until you are familiar with Emacspeak.

    Ok, I hit C-h m,and it waits for me to give a menu name. How do I get
    to a place where I can hit 'i' to look up a topic in the "index"?
    I see that 's' asks me for a regex to search for, and it searches
    down the page, from the current cursor location to find it.
    Is there a separate index page for each node? Or maybe only some nodes?

I probably wasn't clear enough.

C-h i            -- enters Info
Click Emacs link -- enter Emacs manual
C-h m            -- get help on Info mode

Read the Info mode help; it describes key bindings in Info mode, including
these bindings (you may have to scroll down the *Help* window a bit (use C-x
o to switch windows):

i	Look up a topic in this file's Index and move to that node.
s	Search through this Info file for specified regexp,
	  and select the node in which the next occurrence is found.

In buffer (window) *info*, use `C-x 1' to get rid of the *Help* window.

It is in Info mode (buffer *info*) that you can use the Info-mode key
bindings such as `i' and `s'.

My guess is that you used simply `m' in Info mode, not `C-h m'. `m' asks for
a menu item to visit.

`s' and `i' are totally separate. `s' simply searches; `i' looks up a term
in the manual's index.

`s' searches for a regexp, but that can be as simple as a word. You can use
`s' again, hitting just `RET' (Return key) to reuse the last input (e.g.
word). So, for example, `s indentation RET' finds the first occurrence in
the manual of "indentation". Then, `s RET' finds the next occurrence of
"indentation". Repeat `s RET' as needed. As I mentioned, when appropriate,
`i' is much quicker; in this case it takes you directly to the manual
section on indentation.

HTH.

Ah. I get it now. "Info" mode is just like any other mode. :)

Also: C-h m == M-x describe-mode

Got it. I previously had a problem with that because I wasn't first
at the Emacs node before hitting 'i'. Thanks.

Yes. 'm' gets to to where a menu item leads if I can type it in by name.

It does help. Thanks Drew. It's interesting how similar the info program
works compared to something like lynx (that is, if your docs were just
in html, and you used a text-mode html browser to access them). The main
difference I'm seeing right now is, that info nodes have an order to them
(you can hit 'n' for next, 'p' for previous) as well as having links
("menus" and "cross-references"), whereas html has only links.

The other (more important, IMHO) difference is that Info can search
via the index (the `i' command), which is much more efficient way of
finding things quickly, i.e. using a manual like a reference.

Why would you test global-font-lock-mode's function binding, then set
its variable binding?  Especially since its doc string tells you to call
the function: (global-font-lock-mode 1)

Because I make mistakes and do not read everything ... I'll correct  
my .emacs! Thanks!
