;;;; Commentary:
;;
;; In some cases you may find that it is quite hard to write one major
;; mode that does everything for the type of file you want to handle.
;; That is the case for example for a PHP file where there comes
;; useful major modes with Emacs for the html parts, and where you can
;; get a major mode for PHP from other sources (see EmacsWiki for
;; Aaron Hawleys php-mode.el, or the very similar version that comes
;; with nXhtml).
;;
;; Using one major mode for the HTML part and another for the PHP part
;; sounds like a good solution. But this means you want to use (at
;; least) two major modes in the same buffer.
;;
;; This file implements just that, support for MUltiple MAjor MOdes
;; (mumamo) in a buffer.
;;
;;
;;;; Usage:
;;
;; The multiple major mode support is turned on by calling special
;; functions which are used nearly the same way as major modes. See
;; `mumamo-defined-multi-major-modes' for more information about those
;; functions.
;;
;; Each such function defines how to take care of a certain mix of
;; major functions in the buffer. We call them "multi major modes".
;;
;; You may call those functions directly (like you can with major mode
;; functions) or you may use them in for example `auto-mode-alist'.
;;
;; You can load mumamo in your .emacs with
;;
;; (require 'mumamo-fun)
;;
;; or you can generate an autoload file from mumamo-fun.el
;;
;; Note that no multi major mode functions are defined in this file.
;; Together with this file comes the file mumamo-fun.el that defines
;; some such functions. All those functions defined in that file are
;; marked for autoload.
;;
;;
;;
;; Thanks to Stefan Monnier for beeing a good and knowledgeable
;; speaking partner for some difficult parts while I was trying to
;; develop this.
;;
;; Thanks to RMS for giving me support and ideas about the programming
;; interface. That simplified the code and usage quite a lot.
;;
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;;; How to add support for a new mix of major modes
;;
;; This is done by creating a new function using
;; `define-mumamo-multi-major-mode'. See that function for more
;; information.
;;
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;;; Information for major mode authors
;;
;; There are a few special requirements on major modes to make them
;; work with mumamo:
;;
;; - fontification-functions should be '(jit-lock-function). However
;; nxml-mode derivates can work too, see the code for more info.
;;
;; - narrowing should be respected during fontification and
;; indentation when font-lock-dont-widen is non-nil.
;;
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;;; Information for minor mode authors
;;
;; Some minor modes are written to be specific for the file edited in
;; the buffer and some are written to be specific for a major
;; modes. Others are emulating another editor. Those are probably
;; global, but might still have buffer local values.
;;
;; Those minor modes that are not meant to be specific for a major
;; mode should probably survive changing major mode in the
;; buffer. That is mostly not the case in Emacs today.
;;
;; There are (at least) two type of values for those minor modes that
;; sometimes should survive changing major mode: buffer local
;; variables and functions added locally to hooks.
;;
;; * Some buffer local variables are really that - buffer local. Other
;; are really meant not for the buffer but for the major mode or
;; some minor mode that is local to the buffer.
;;
;; If the buffer local variable is meant for the buffer then it is
;; easy to make them survive changing major mode: just add
;;
;; (put 'VARIABLE 'permanent-local t)
;;
;; to those variables. That will work regardless of the way major
;; mode is changed.
;;
;; If one only wants the variables to survive the major mode change
;; that is done when moving between chunks with different major
;; modes then something different must be used. To make a variable
;; survive this, but not a major mode change for the whole buffer,
;; call any the function `mumamo-make-variable-buffer-permanent':
;;
;; (mumamo-make-variable-buffer-permanent 'VARIABLE)
;;
;; * For functions entered to local hooks use this
;;
;; (put 'FUNSYM 'permanent-local-hook t)
;; (add-hook 'HOOKSYM 'FUNSYM nil t)
;;
;; where HOOKSYM is the hook and FUNSYM is the function.
;;
;; * Some functions that are run in `change-major-mode' and dito
;; after- must be avoided when mumamo changes major mode. The
;; functions to avoid should be listed in
;;
;; `mumamo-change-major-mode-no-nos'
;; `mumamo-after-change-major-mode-no-nos'
;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;;;; Comments on code etc:
;;
;; This is yet another way to try to get different major modes for
;; different chunks of a buffer to work. (I borrowed the term "chunk"
;; here from multi-mode.el.) I am aware of two main previous elisp
;; packages that tries to do this, multi-mode.el and mmm-mode.el.
;; (See http://www.emacswiki.org/cgi-bin/wiki/MultipleModes where
;; there are also some other packages mentioned.) The solutions in
;; those are a bit different from the approach here.
;;
;; The idea of doing it the way mumamo does it is of course based on a
;; hope that switching major mode when moving between chunks should be
;; quick. I found that it took from 0 - 62 000 ms, typically 0 - 16
;; 000 ms on a 3ghz cpu. However unfortunately this is not the whole
;; truth. It could take longer time, depending on what is run in the
;; hooks: The major mode specific hook, `after-change-major-mode-hook'
;; and `change-major-mode-hook'.
;;
;; Because it currently may take long enough time switching major mode
;; when moving between chunks to disturb smooth moving around in the
;; buffer I have added a way to let the major mode switching be done
;; after moving when Emacs is idle. This is currently the default, but
;; see the custom variable `mumamo-set-major-mode-delay'.
;;
;; Since the intention is to set up the new major mode the same way as
;; it should have been done if this was a major mode for the whole
;; buffer these hooks must be run. However if this idea is developed
;; further some of the things done in these hooks (like switching on
;; minor modes) could perhaps be streamlined so that switching minor
;; modes off and then on again could be avoided. In fact there is
;; already tools for this in mumamo.el, see the section below named
;; "Information for minor mode authors".
;;
;; Another problem is that the major modes must use
;; `font-lock-fontify-region-function'. Currently the only major
;; modes I know that does not do this are `nxml-mode' and its
;; derivatives.
;;
;; The indentation is currently working rather ok, but with the price
;; that buffer modified is sometimes set even though there are no
;; actual changes. That seems a bit unnecessary and it could be
;; avoided if the indentation functions for the the various major
;; modes were rewritten so that you could get the indentation that
;; would be done instead of actually doing the indentation. (Or
;; mumamo could do this better, but I do not know how right now.)

;;
;;;; Known problems and ideas:

"Define a function that turn on support for multiple major modes.
Define a function FUN-SYM that set up to divide the current
buffer into chunks with different major modes.
The documentation string for FUN-SYM should contain the special
documentation in the string SPEC-DOC, general documentation for
functions of this type and information about chunks.
The new function will use the definitions in CHUNKS \(which is
called a \"chunk family\") to make the dividing of the buffer.
The function FUN-SYM can be used to setup a buffer instead of a
major mode function:
- The function FUN-SYM can be called instead of calling a major
mode function when you want to use multiple major modes in a
buffer.
- The defined function can be used instead of a major mode
function in for example `auto-mode-alist'.
- As the very last thing FUN-SYM will run the hook FUN-SYM-hook,
just as major modes do.
- There is also a general hook, `mumamo-turn-on-hook', which is
run when turning on mumamo with any of these functions. This
is run right before the hook specific to any of the functions
above that turns on the multiple major mode support.
- The multi major mode FUN-SYM has a keymap named FUN-SYM-map.
This overrides the major modes' keymaps since it is handled as
a minor mode keymap.
- There is also a special mumamo keymap, `mumamo-map' that is
active in every buffer with a multi major mode. This is also
handled as a minor mode keymap and therefor overrides the major
modes' keymaps.
- However when this support for multiple major mode is on the
buffer is divided into chunks, each with its own major mode.
- The chunks are fontified according the major mode assigned to
them for that.
- Indenting is also done according to the major mode assigned to
them for that.
- The actual major mode used in the buffer is changed to the one
in the chunk when moving point between these chunks.
- When major mode is changed the hooks for the new major mode,
`after-change-major-mode-hook' and `change-major-mode-hook' are
run.
- There will be an alias for FUN-SYM called mumamo-alias-FUN-SYM.
This can be used to check whic multi major modes have been
defined.
** A little bit more technical description:
The dividing of a buffer into chunks is done during fontification
by `mumamo-get-chunk-at'.
The name of the function is saved in in the buffer local variable
`mumamo-multi-major-mode' when the function is called.
All functions defined by this macro is added to the list
`mumamo-defined-multi-major-modes'.
Basically Mumamo handles only major modes that uses jit-lock.
However as a special effort also `nxml-mode' and derivatives
thereof are handled. Since it seems impossible to me to restrict
those major modes fontification to only a chunk without changing
`nxml-mode' the fontification is instead done by
`html-mode'/`sgml-mode' for chunks using `nxml-mode' and its
derivates.
CHUNKS is a list where each entry have the format
\(CHUNK-DEF-NAME MAIN-MAJOR-MODE SUBMODE-CHUNK-FUNCTIONS)
CHUNK-DEF-NAME is the key name by which the entry is recognized.
MAIN-MAJOR-MODE is the major mode used when there is no chunks.
If this is nil then `major-mode' before turning on this mode will
be used.
SUBMODE-CHUNK-FUNCTIONS is a list of the functions that does the
chunk division of the buffer. They are tried in the order they
appear here during the chunk division process.
If you want to write new functions for chunk divisions then
please see `mumamo-find-possible-chunk'. You can perhaps also
use `mumamo-quick-static-chunk' which is more easy-to-use
alternative. See also the file mumamo-fun.el where there are
many routines for chunk division.
When you write those new functions you may want to use some of
the functions for testing chunks:
`mumamo-test-create-chunk-at' `mumamo-test-create-chunks-at-all'
`mumamo-test-easy-make' `mumamo-test-fontify-region'
These are in the file mumamo-test.el."

This function is called a multi major mode. It sets up for
multiple major modes in the buffer in the following way:
"
;; Fix-me: During byte compilation the next line is not
;; expanded as I thought because the functions in CHUNKS
;; are not defined. How do I fix this? Move out the
;; define-mumamo-multi-major-mode calls?
(funcall 'mumamo-describe-chunks chunks2)
"
At the very end this multi major mode function runs first the hook
`mumamo-turn-on-hook' and then `" (symbol-name turn-on-hook) "'.
There is a keymap specific to this multi major mode, but it is
not returned by `current-local-map' which returns the chunk's
major mode's local keymap.
The multi mode keymap is named `" (symbol-name turn-on-map) "'.
The main use for a multi major mode is to use it instead of a
normal major mode in `auto-mode-alist'. \(You can of course call
this function directly yourself too.)
The value of `mumamo-multi-major-mode' tells you which multi
major mode if any has been turned on in a buffer. For more
information about multi major modes please see
`define-mumamo-multi-major-mode'.
Note: When adding new font-lock keywords for major mode chunks
you should use the function `mumamo-refresh-multi-font-lock'
afterwards.

"Alist for conversion of chunk major mode specifier to major mode.
Each entry has the form
\(MAJOR-SPEC MAJORMODE ...)
where the symbol MAJOR-SPEC specifies the code type and should
match the value returned from `mumamo-find-possible-chunk'. The
MAJORMODE symbols are major modes that can be used for editing
that code type. The first available MAJORMODE is the one that is
used.
The MAJOR-SPEC symbols are used by the chunk definitions in
`define-mumamo-multi-major-mode'.
The major modes are not specified directly in the chunk
definitions. Instead a chunk definition contains a symbol that
is looked up in this list to find the chunk's major mode.
The reason for doing it this way is to make it possible to use
new major modes with existing multi major modes. If for example
someone writes a new CSS mode that could easily be used instead
of the current one in `html-mumamo-mode'.
Lookup in this list is done by `mumamo-major-mode-from-modespec'."

If VERBOSE is non-nil then print status messages during

This is called from `mumamo-fontify-region' which is the value of
`font-lock-fontify-region-function' when mumamo is used. \(This
means that it ties into the normal font lock framework in Emacs.)
Note: The purpose of extracting this function from
`mumamo-fontify-region' \(which is the only place where it is
called) is to make debugging easier. Edebug will without this
function just step over the `condition-case' in
`mumamo-fontify-region'.
The fontification is done in steps:
- First a mumamo chunk is found or created at the start of the
region with `mumamo-get-chunk-at'.
- Then this chunk is fontified according to the major mode for
that chunk.
- If the chunk did not encompass the whole region then this
procedure is repeated with the rest of the region.
If some mumamo chunk in the region between START and END has been
marked for removal \(for example by `mumamo-jit-lock-after-change') then
they are removed by this function.
For some main major modes \(see `define-mumamo-multi-major-mode') the
main major modes is first used to fontify the whole region. This
is because otherwise the fontification routines for that mode may
have trouble finding the correct starting state in a chunk.
Special care has been taken for chunks that are strings, ie
surrounded by \"...\" since they are fontified a bit special in
most major modes."

major mode specifier for this chunk. \(Note that this specifier
is translated to a major mode through `mumamo-major-modes'.)
PARSEABLE-BY is a list of parsers that can handle the chunk
beside the one that may be used by the chunks major mode.
Currently only the XML parser in `nxml-mode' is recognized. In
this list it should be the symbol `nxml-mode'.
The functions FW-EXC-START-FUN and FW-EXC-END-FUN should search
for exception start or end, forward resp backward. Those two
takes two parameters, start position POS and max position MAX,
and should return just the start respectively the end of the
chunk.
For all three functions the position returned should be nil if
search fails.
Return as a list with values
\(START END EXCEPTION-MODE BORDERS PARSEABLE-BY FR-EXC-FUN FIND-BORDERS-FUN)
**Fix-me: FIND-BORDERS-FUN must be split for chunks-in-chunks!
The bounds START and END are where the exception starts or stop.
Either of them may be nil, in which case this is equivalent to
`point-min' respectively `point-max'.
If EXCEPTION-MODE is non-nil that is the submode for this
range. Otherwise the main major mode should be used for this
chunk.
BORDERS is the return value of the optional FIND-BORDERS-FUN
which takes three parameters, START, END and EXCEPTION-MODE in
the return values above. BORDERS may be nil and otherwise has
this format:
\(START-BORDER END-BORDER EXCEPTION-MODE FW-EXC-FUN)
START-BORDER and END-BORDER may be nil. Otherwise they should be
the position where the border ends respectively start at the
corresponding end of the chunk.
PARSEABLE-BY is a list of major modes with parsers that can parse
the chunk.
FW-EXC-FUN is the function that finds the end of the chunk. This
is either FW-EXC-START-FUN or FW-EXC-END-FUN.
---- * Note: This routine is used by to create new members for
chunk families. If you want to add a new chunk family you could
most often do that by writing functions for this routine. Please
see the many examples in mumamo-fun.el for how this can be done.

"Indent current line.
When doing that care must be taken if this line's major modes at
the start and end are different from previous line major modes.
The latter may be known through the parameter PREV-LINE-CHUNKS.
Also the indentation of the last previous main major line may be
necessary to know. This may be known through the parameter
LAST-PARENT-MAJOR-INDENT.
If the two parameters above are nil then this function will
search backwards in the buffer to try to determine their values.
The following rules are used when indenting:
- If the major modes are the same in this and the previous line
then indentation is done using that major mode.
- Exception: If the chunks are not the same AND there is
precisely one chunk between them which have the property value
of 'mumamo-next-indent equal to 'mumamo-template-indentor then
a special indent using the content of the middle chunk is
done. An example of this is eRuby where a middle chunk could
look like:
<% 3.times do %>
This example will increase indentation for the next line the
same way as the chunk content would do in single major mode
ruby-mode.
FIXE-ME: IMPLEMENT THE ABOVE!
- Otherwise if going into a submode indentation is increased by
`mumamo-submode-indent-offset' (if this is nil then indentation
will instead be 0).
- However first non-empty line indentation in a chunk when going
in is special if prev-prev chunk is on same mumamo-depth and
have the same major mode. Then indent relative last non-empty
line in prev-prev chunk.
- When going out of a submode indentation is reset to
LAST-PARENT-MAJOR-INDENT.
- At the border the 'dividers' should be indented as the parent
chunk. There are the following typical situations regarding
inner/outer major modes:
1) <style type='text/css'>
Going in next line; first char outer; line end inner;
2) </style>
Going out this line; First char inner or outer; line end outer;
3) <?php
Going in next line; first char outer or inner; line end inner;
4) ?>
Going out this line; first char inner; line end outer;
From this we deduce the following way to compute if we are
going in or out:
- Odd above (going in): Compare prev line end's mumamo-depth
with current line end's dito. Set flag for first line in
chunk.
- Even above (going out): Same test as for going in, but going
out happens on current line.

;; things in `font-lock-apply-syntactic-highlight' seems to show that.
;;
;; (I have put in some dump code in my patched version of
;; Emacs+EmacsW32 there for that. This is commented out by default
;; and it will only work for the file nxhtml-changes.html which is big
;; enough for the problem to occur. It happens at point 1109.)
;;
;; It is this piece of code where the problem arise:
;;
;; (if (prog1
;; (zerop (car (syntax-ppss (match-beginning 0))))
;; (goto-char (match-end 0)))
;; .)
;;
;;
;; It comes from `sgml-font-lock-syntactic-keywords' in sgml-mode.el
;; and is supposed to protect from " that is not inside a tag.
;; However in this case for the second " in syntax="..." `syntax-ppss'
;; returns 0 as the first element in its return value. That happen
;; even though `major-mode' is correctly `html-mode'. It leads to
;; that the property 'syntax with the value (1) is added to the "
;; after the css-mode chunk in syntax="...". The problem persists
;; even if the chunk has `fundamental-mode' instead of `css-mode'.
;;
;; Bypassing the cache for `syntax-pss' by calling
;; `parse-partial-sexp' directly instead of doing ad-do-it (see
;; by-pass-chache in the code below) solves the problem for now. It
;; does not feel like the right solution however.

Compute the beginning parse state for a chunk this way:

doing that jump over chunks that do not belong to the main

FIX-ME: implement above. Solution?:
