Catching Errors with TeX Formatting
===================================

  You can also catch mistakes when you format a file with TeX.

  Usually, you will want to do this after you have run
`texinfo-format-buffer' (or, better, `makeinfo-buffer') on the same
file, because `texinfo-format-buffer' sometimes displays error messages
that make more sense than TeX.  (*Note Debugging with Info::, for more
information.)

  For example, TeX was run on a Texinfo file, part of which is shown
here:

     ---------- Buffer: texinfo.texi ----------
     name of the Texinfo file as an extension.  The
     @samp{??} are `wildcards' that cause the shell to
     substitute all the raw index files.  (@xref{sorting
     indices, for more information about sorting
     indices.)@refill
     ---------- Buffer: texinfo.texi ----------

(The cross reference lacks a closing brace.)  TeX produced the
following output, after which it stopped:

     ---------- Buffer: *tex-shell* ----------
     Runaway argument?
     {sorting indices, for more information about sorting
     indices.) @refill @ETC.
     ! Paragraph ended before @xref was complete.
     <to be read again>
                        @par
     l.27
     
     ?
     ---------- Buffer: *tex-shell* ----------

  In this case, TeX produced an accurate and understandable error
message:

     Paragraph ended before @xref was complete.

`@par' is an internal TeX command of no relevance to Texinfo.  `l.27'
means that TeX detected the problem on line 27 of the Texinfo file.
The `?' is the prompt TeX uses in this circumstance.

  Unfortunately, TeX is not always so helpful, and sometimes you must
truly be a Sherlock Holmes to discover what went wrong.

  In any case, if you run into a problem like this, you can do one of
three things.

  1. You can tell TeX to continue running and ignore just this error by
     typing <RET> at the `?' prompt.

  2. You can tell TeX to continue running and to ignore all errors as
     best it can by typing `r <RET>' at the `?' prompt.

     This is often the best thing to do.  However, beware: the one error
     may produce a cascade of additional error messages as its
     consequences are felt through the rest of the file.  To stop TeX
     when it is producing such an avalanche of error messages, type
     `C-c' (or `C-c C-c', if you are running a shell inside Emacs).

  3. You can tell TeX to stop this run by typing `x <RET>' at the `?'
     prompt.

  If you are running TeX inside Emacs, you need to switch to the shell
buffer and line at which TeX offers the `?' prompt.

  Sometimes TeX will format a file without producing error messages even
though there is a problem.  This usually occurs if a command is not
ended but TeX is able to continue processing anyhow.  For example, if
you fail to end an itemized list with the `@end itemize' command, TeX
will write a DVI file that you can print out.  The only error message
that TeX will give you is the somewhat mysterious comment that

     (@end occurred inside a group at level 1)

However, if you print the DVI file, you will find that the text of the
file that follows the itemized list is entirely indented as if it were
part of the last item in the itemized list.  The error message is the
way TeX says that it expected to find an `@end' command somewhere in
the file; but that it could not determine where it was needed.

  Another source of notoriously hard-to-find errors is a missing `@end
group' command.  If you ever are stumped by incomprehensible errors,
look for a missing `@end group' command first.

  If the Texinfo file lacks header lines, TeX may stop in the beginning
of its run and display output that looks like the following.  The `*'
indicates that TeX is waiting for input.

     This is TeX, Version 3.14159 (Web2c 7.0)
     (test.texinfo [1])
     *

In this case, simply type `\end <RET>' after the asterisk.  Then write
the header lines in the Texinfo file and run the TeX command again.
(Note the use of the backslash, `\'.  TeX uses `\' instead of `@'; and
in this circumstance, you are working directly with TeX, not with
Texinfo.)


File: texinfo,  Node: Using texinfo-show-structure,  Next: Using occur,  Prev: Debugging with TeX,  Up: Catching Mistakes

Using `texinfo-show-structure'
==============================

  It is not always easy to keep track of the nodes, chapters, sections,
and subsections of a Texinfo file.  This is especially true if you are
revising or adding to a Texinfo file that someone else has written.

  In GNU Emacs, in Texinfo mode, the `texinfo-show-structure' command
lists all the lines that begin with the @-commands that specify the
structure: `@chapter', `@section', `@appendix', and so on.  With an
argument (`C-u' as prefix argument, if interactive), the command also
shows the `@node' lines.  The `texinfo-show-structure' command is bound
to `C-c C-s' in Texinfo mode, by default.

  The lines are displayed in a buffer called the `*Occur*' buffer,
indented by hierarchical level.  For example, here is a part of what was
produced by running `texinfo-show-structure' on this manual:

      Lines matching "^@\\(chapter \\|sect\\|subs\\|subh\\|
      unnum\\|major\\|chapheading \\|heading \\|appendix\\)"
      in buffer texinfo.texi.
      ...
      4177:@chapter Nodes
      4198:    @heading Two Paths
      4231:    @section Node and Menu Illustration
      4337:    @section The @code{@@node} Command
      4393:        @subheading Choosing Node and Pointer Names
      4417:        @subsection How to Write an @code{@@node} Line
      4469:        @subsection @code{@@node} Line Tips
      ...

  This says that lines 4337, 4393, and 4417 of `texinfo.texi' begin
with the `@section', `@subheading', and `@subsection' commands
respectively.  If you move your cursor into the `*Occur*' window, you
can position the cursor over one of the lines and use the `C-c C-c'
command (`occur-mode-goto-occurrence'), to jump to the corresponding
spot in the Texinfo file.  *Note Using Occur: (emacs)Other Repeating
Search, for more information about `occur-mode-goto-occurrence'.

  The first line in the `*Occur*' window describes the "regular
expression" specified by TEXINFO-HEADING-PATTERN.  This regular
expression is the pattern that `texinfo-show-structure' looks for.
*Note Using Regular Expressions: (emacs)Regexps, for more information.

  When you invoke the `texinfo-show-structure' command, Emacs will
display the structure of the whole buffer.  If you want to see the
structure of just a part of the buffer, of one chapter, for example,
use the `C-x n n' (`narrow-to-region') command to mark the region.
(*Note Narrowing: (emacs)Narrowing.)  This is how the example used
above was generated.  (To see the whole buffer again, use `C-x n w'
(`widen').)

  If you call `texinfo-show-structure' with a prefix argument by typing
`C-u C-c C-s', it will list lines beginning with `@node' as well as the
lines beginning with the @-sign commands for `@chapter', `@section',
and the like.

  You can remind yourself of the structure of a Texinfo file by looking
at the list in the `*Occur*' window; and if you have mis-named a node
or left out a section, you can correct the mistake.


File: texinfo,  Node: Using occur,  Next: Running Info-Validate,  Prev: Using texinfo-show-structure,  Up: Catching Mistakes

Using `occur'
=============

  Sometimes the `texinfo-show-structure' command produces too much
information.  Perhaps you want to remind yourself of the overall
structure of a Texinfo file, and are overwhelmed by the detailed list
produced by `texinfo-show-structure'.  In this case, you can use the
`occur' command directly.  To do this, type

     M-x occur

and then, when prompted, type a "regexp", a regular expression for the
pattern you want to match.  (*Note Regular Expressions:
(emacs)Regexps.)  The `occur' command works from the current location
of the cursor in the buffer to the end of the buffer.  If you want to
run `occur' on the whole buffer, place the cursor at the beginning of
the buffer.

  For example, to see all the lines that contain the word `@chapter' in
them, just type `@chapter'.  This will produce a list of the chapters.
It will also list all the sentences with `@chapter' in the middle of
the line.

  If you want to see only those lines that start with the word
`@chapter', type `^@chapter' when prompted by `occur'.  If you want to
see all the lines that end with a word or phrase, end the last word
with a `$'; for example, `catching mistakes$'.  This can be helpful
when you want to see all the nodes that are part of the same chapter or
section and therefore have the same `Up' pointer.

  *Note Using Occur: (emacs)Other Repeating Search, for more
information.


File: texinfo,  Node: Running Info-Validate,  Prev: Using occur,  Up: Catching Mistakes

Finding Badly Referenced Nodes
==============================

  You can use the `Info-validate' command to check whether any of the
`Next', `Previous', `Up' or other node pointers fail to point to a
node.  This command checks that every node pointer points to an
existing node.  The `Info-validate' command works only on Info files,
not on Texinfo files.

  The `makeinfo' program validates pointers automatically, so you do
not need to use the `Info-validate' command if you are using
`makeinfo'.  You only may need to use `Info-validate' if you are unable
to run `makeinfo' and instead must create an Info file using
`texinfo-format-region' or `texinfo-format-buffer', or if you write an
Info file from scratch.

* Unsplit::                     How to create an unsplit file.
* Tagifying::                   How to tagify a file.
* Splitting::                   How to split a file manually.


File: texinfo,  Node: Using Info-validate,  Next: Unsplit,  Prev: Running Info-Validate,  Up: Running Info-Validate

Running `Info-validate'
-----------------------

  To use `Info-validate', visit the Info file you wish to check and
type:

     M-x Info-validate

Note that the `Info-validate' command requires an upper case `I'.  You
may also need to create a tag table before running `Info-validate'.
*Note Tagifying::.

  If your file is valid, you will receive a message that says "File
appears valid".  However, if you have a pointer that does not point to
a node, error messages will be displayed in a buffer called `*problems
in info file*'.

  For example, `Info-validate' was run on a test file that contained
only the first node of this manual.  One of the messages said:

     In node "Overview", invalid Next: Texinfo Mode

This meant that the node called `Overview' had a `Next' pointer that
did not point to anything (which was true in this case, since the test
file had only one node in it).

  Now suppose we add a node named `Texinfo Mode' to our test case but
we do not specify a `Previous' for this node.  Then we will get the
following error message:

     In node "Texinfo Mode", should have Previous: Overview

This is because every `Next' pointer should be matched by a `Previous'
(in the node where the `Next' points) which points back.

  `Info-validate' also checks that all menu entries and cross references
point to actual nodes.

  `Info-validate' requires a tag table and does not work with files
that have been split.  (The `texinfo-format-buffer' command
automatically splits large files.)  In order to use `Info-validate' on
a large file, you must run `texinfo-format-buffer' with an argument so
that it does not split the Info file; and you must create a tag table
for the unsplit file.


File: texinfo,  Node: Unsplit,  Next: Tagifying,  Prev: Using Info-validate,  Up: Running Info-Validate

Creating an Unsplit File
------------------------

  You can run `Info-validate' only on a single Info file that has a tag
table.  The command will not work on the indirect subfiles that are
generated when a master file is split.  If you have a large file
(longer than 70,000 bytes or so), you need to run the
`texinfo-format-buffer' or `makeinfo-buffer' command in such a way that
it does not create indirect subfiles.  You will also need to create a
tag table for the Info file.  After you have done this, you can run
`Info-validate' and look for badly referenced nodes.

  The first step is to create an unsplit Info file.  To prevent
`texinfo-format-buffer' from splitting a Texinfo file into smaller Info
files, give a prefix to the `M-x texinfo-format-buffer' command:

     C-u M-x texinfo-format-buffer

or else

     C-u C-c C-e C-b

When you do this, Texinfo will not split the file and will not create a
tag table for it.


File: texinfo,  Node: Tagifying,  Next: Splitting,  Prev: Unsplit,  Up: Running Info-Validate

Tagifying a File
----------------

  After creating an unsplit Info file, you must create a tag table for
it.  Visit the Info file you wish to tagify and type:

     M-x Info-tagify

(Note the upper case `I' in `Info-tagify'.)  This creates an Info file
with a tag table that you can validate.

  The third step is to validate the Info file:

     M-x Info-validate

(Note the upper case `I' in `Info-validate'.)  In brief, the steps are:

     C-u M-x texinfo-format-buffer
     M-x Info-tagify
     M-x Info-validate

  After you have validated the node structure, you can rerun
`texinfo-format-buffer' in the normal way so it will construct a tag
table and split the file automatically, or you can make the tag table
and split the file manually.


File: texinfo,  Node: Splitting,  Prev: Tagifying,  Up: Running Info-Validate

Splitting a File Manually
-------------------------

  You should split a large file or else let the `texinfo-format-buffer'
or `makeinfo-buffer' command do it for you automatically.  (Generally
you will let one of the formatting commands do this job for you.  *Note
Creating an Info File::.)

  The split-off files are called the indirect subfiles.

  Info files are split to save memory.  With smaller files, Emacs does
not have make such a large buffer to hold the information.

  If an Info file has more than 30 nodes, you should also make a tag
table for it. *Note Using Info-validate::, for information about
creating a tag table.  (Again, tag tables are usually created
automatically by the formatting command; you only need to create a tag
table yourself if you are doing the job manually.  Most likely, you
will do this for a large, unsplit file on which you have run
`Info-validate'.)

  Visit the Info file you wish to tagify and split and type the two
commands:

     M-x Info-tagify
     M-x Info-split

(Note that the `I' in `Info' is upper case.)

  When you use the `Info-split' command, the buffer is modified into a
(small) Info file which lists the indirect subfiles.  This file should
be saved in place of the original visited file.  The indirect subfiles
are written in the same directory the original file is in, with names
generated by appending `-' and a number to the original file name.

  The primary file still functions as an Info file, but it contains just
the tag table and a directory of subfiles.


File: texinfo,  Node: Refilling Paragraphs,  Next: Command Syntax,  Prev: Catching Mistakes,  Up: Top

Refilling Paragraphs
********************

  The `@refill' command refills and, optionally, indents the first line
of a paragraph.(1) (*note Refilling Paragraphs-Footnote-1::) The
`@refill' command is no longer important, but we describe it here
because you once needed it.  You will see it in many old Texinfo files.

  Without refilling, paragraphs containing long @-constructs may look
bad after formatting because the formatter removes @-commands and
shortens some lines more than others.  In the past, neither the
`texinfo-format-region' command nor the `texinfo-format-buffer' command
refilled paragraphs automatically.  The `@refill' command had to be
written at the end of every paragraph to cause these formatters to fill
them.  (Both TeX and `makeinfo' have always refilled paragraphs
automatically.)  Now, all the Info formatters automatically fill and
indent those paragraphs that need to be filled and indented.

  The `@refill' command causes `texinfo-format-region' and
`texinfo-format-buffer' to refill a paragraph in the Info file _after_
all the other processing has been done.  For this reason, you can not
use `@refill' with a paragraph containing either `@*' or `@w{ ... }'
since the refilling action will override those two commands.

  The `texinfo-format-region' and `texinfo-format-buffer' commands now
automatically append `@refill' to the end of each paragraph that should
be filled.  They do not append `@refill' to the ends of paragraphs that
contain `@*' or `@w{ ...}' and therefore do not refill or indent them.


File: texinfo,  Node: Refilling Paragraphs-Footnotes,  Up: Refilling Paragraphs

  (1) Perhaps the command should have been called the
`@refillandindent' command, but `@refill' is shorter and the name was
chosen before indenting was possible.


File: texinfo,  Node: Command Syntax,  Next: Obtaining TeX,  Prev: Refilling Paragraphs,  Up: Top

@-Command Syntax
****************

  The character `@' is used to start special Texinfo commands.  (It has
the same meaning that `\' has in plain TeX.)  Texinfo has four types of
@-command:

1. Non-alphabetic commands.
     These commands consist of an @ followed by a punctuation mark or
     other character that is not part of the alphabet.  Non-alphabetic
     commands are almost always part of the text within a paragraph,
     and never take any argument.  The two characters (@ and the other
     one) are complete in themselves; none is followed by braces.  The
     non-alphabetic commands are: `@.', `@:', `@*', `@SPACE', `@TAB',
     `@NL', `@@', `@{', and `@}'.

2. Alphabetic commands that do not require arguments.
     These commands start with @ followed by a word followed by left-
     and right-hand braces.  These commands insert special symbols in
     the document; they do not require arguments.  For example,
     `@dots{}' => `...', `@equiv{}' => `==', `@TeX{}' => `TeX', and
     `@bullet{}' => `*'.

3. Alphabetic commands that require arguments within braces.
     These commands start with @ followed by a letter or a word,
     followed by an argument within braces.  For example, the command
     `@dfn' indicates the introductory or defining use of a term; it is
     used as follows: `In Texinfo, @@-commands are @dfn{mark-up}
     commands.'

4. Alphabetic commands that occupy an entire line.
     These commands occupy an entire line.  The line starts with @,
     followed by the name of the command (a word); for example,
     `@center' or `@cindex'.  If no argument is needed, the word is
     followed by the end of the line.  If there is an argument, it is
     separated from the command name by a space.  Braces are not used.

  Thus, the alphabetic commands fall into classes that have different
argument syntaxes.  You cannot tell to which class a command belongs by
the appearance of its name, but you can tell by the command's meaning:
if the command stands for a glyph, it is in class 2 and does not
require an argument; if it makes sense to use the command together with
other text as part of a paragraph, the command is in class 3 and must
be followed by an argument in braces; otherwise, it is in class 4 and
uses the rest of the line as its argument.

  The purpose of having a different syntax for commands of classes 3 and
4 is to make Texinfo files easier to read, and also to help the GNU
Emacs paragraph and filling commands work properly.  There is only one
exception to this rule: the command `@refill', which is always used at
the end of a paragraph immediately following the final period or other
punctuation character.  `@refill' takes no argument and does _not_
require braces.  `@refill' never confuses the Emacs paragraph commands
because it cannot appear at the beginning of a line.
