;;; Commentary:
;; IDLWAVE enables feature-rich development and interaction with IDL,
;; the Interactive Data Language. It provides a compelling,
;; full-featured alternative to the IDLDE development environment
;; bundled with IDL.
;; In the remotely distant past, based on pascal.el, though bears
;; little resemblance to it now.
;;
;; Incorporates many ideas, such as abbrevs, action routines, and
;; continuation line indenting, from wave.el.
;; wave.el original written by Lubos Pochman, Precision Visuals, Boulder.
;;
;; See the mode description ("C-h m" in idlwave-mode or "C-h f idlwave-mode")
;; for features, key bindings, and info.
;; Also, Info format documentation is available with `M-x idlwave-info'

;;
;; CUSTOMIZATION:
;; =============
;;
;; IDLWAVE has extensive customize support; to learn about the
;; variables which control the mode's behavior, use `M-x
;; idlwave-customize'.
;;
;; You can set your own preferred values with Customize, or with Lisp
;; code in .emacs. For an example of what to put into .emacs, check
;; the TexInfo documentation or see a complete .emacs available at the
;; website.
;;
;; KNOWN PROBLEMS:
;; ==============
;;
;; IDLWAVE support for the IDL-derived PV-WAVE CL language of Visual
;; Numerics, Inc. is growing less and less complete as the two
;; languages grow increasingly apart. The mode probably shouldn't
;; even have "WAVE" in its title, but it's catchy, and was required
;; to avoid conflict with the CORBA idl.el mode. Caveat WAVEor.
;;
;; Moving the point backwards in conjunction with abbrev expansion
;; does not work as I would like it, but this is a problem with
;; emacs abbrev expansion done by the self-insert-command. It ends
;; up inserting the character that expanded the abbrev after moving
;; point backward, e.g., "\cl" expanded with a space becomes
;; "LONG( )" with point before the close paren. This is solved by
;; using a temporary function in `post-command-hook' - not pretty,
;; but it works.
;;
;; Tabs and spaces are treated equally as whitespace when filling a
;; comment paragraph. To accomplish this, tabs are permanently
;; replaced by spaces in the text surrounding the paragraph, which
;; may be an undesirable side-effect. Replacing tabs with spaces is
;; limited to comments only and occurs only when a comment
;; paragraph is filled via `idlwave-fill-paragraph'.
;;
;; Muti-statement lines (using "&") on block begin and end lines can
;; ruin the formatting. For example, multiple end statements on a
;; line: endif & endif. Using "&" outside of block begin/end lines
;; should be okay.
;;
;; Determining the expression at point for printing and other
;; examination commands is somewhat rough: currently only fairly
;; simple entities are found. You can always drag-select or examine

"Association list governing specification of object classes for completion.
When IDLWAVE tries to complete object-oriented methods, it usually
cannot determine the class of a given object from context. In order
to provide the user with a correct list of methods or keywords, it
needs to determine the appropriate class. IDLWAVE has two ways of
doing this (well, three ways if you count the shell... see
`idlwave-shell-query-for-class'):
1. Combine the items of all available classes which contain this
method for the purpose of completion. So when completing a method,
all methods of all known classes are available, and when completing
a keyword, all keywords allowed for this method in any class are
shown. This behavior is very much like normal completion and is
therefore the default. It works much better than one might think -
only for the INIT, GETPROPERTY and SETPROPERTY the keyword lists
become uncomfortably long. See also
`idlwave-completion-show-classes'.
2. The second possibility is to ask the user on each occasion. To
make this less interruptive, IDLWAVE can store the class as a text
property on the object operator `->'. For a given object in the
source code, class selection will then be needed only once
- for example to complete the method. Keywords to the method can
then be completed directly, because the class is already known.
You will have to turn on the storage of the selected class
explicitly with the variable `idlwave-store-inquired-class'.
This variable allows you to configure IDLWAVE's method and
method-keyword completion behavior. Its value is an alist, which
should contain at least two elements: (method-default . VALUE) and
\(keyword-default . VALUE), where VALUE is either t or nil. These
specify if the class should be found during method and keyword
completion, respectively.
The alist may have additional entries specifying exceptions from the
keyword completion rule for specific methods, like INIT or
GETPROPERTY. In order to turn on class specification for the INIT
method, add an entry (\"INIT\" . t). The method name must be ALL-CAPS."

"KEY and CMD are made into a key binding and an indent action.
KEY is a string - same as for the `define-key' function. CMD is a
function of no arguments or a list to be evaluated. CMD is bound to
KEY in `idlwave-mode-map' by defining an anonymous function calling
`self-insert-command' followed by CMD. If KEY contains more than one
character a binding will only be set if SELECT is `both'.
\(KEY . CMD) is also placed in the `idlwave-indent-expand-table',
replacing any previous value for KEY. If a binding is not set then it
will instead be placed in `idlwave-indent-action-table'.
If the optional argument SELECT is nil then an action and binding are
created. If SELECT is `noaction', then a binding is always set and no
action is created. If SELECT is `both' then an action and binding
will both be created even if KEY contains more than one character.
Otherwise, if SELECT is non-nil then only an action is created.
Some examples:
No spaces before and 1 after a comma
(idlwave-action-and-binding \",\" \\='(idlwave-surround 0 1))
A minimum of 1 space before and after `=' (see `idlwave-expand-equal').

(define-derived-mode idlwave-mode prog-mode "IDLWAVE"
"Major mode for editing IDL source files (version 6.1_em22).
The main features of this mode are
1. Indentation and Formatting
--------------------------
Like other Emacs programming modes, C-j inserts a newline and indents.
TAB is used for explicit indentation of the current line.
To start a continuation line, use \\[idlwave-split-line]. This
function can also be used in the middle of a line to split the line
at that point. When used inside a long constant string, the string
is split at that point with the `+' concatenation operator.
Comments are indented as follows:
`;;;' Indentation remains unchanged.
`;;' Indent like the surrounding code
`;' Indent to a minimum column.
The indentation of comments starting in column 0 is never changed.
Use \\[idlwave-fill-paragraph] to refill a paragraph inside a
comment. The indentation of the second line of the paragraph
relative to the first will be retained. Use
\\[idlwave-auto-fill-mode] to toggle auto-fill mode for these
comments. When the variable `idlwave-fill-comment-line-only' is
nil, code can also be auto-filled and auto-indented.
To convert pre-existing IDL code to your formatting style, mark the
entire buffer with \\[mark-whole-buffer] and execute
\\[idlwave-expand-region-abbrevs]. Then mark the entire buffer
again followed by \\[indent-region] (`indent-region').
2. Routine Info
------------
IDLWAVE displays information about the calling sequence and the
accepted keyword parameters of a procedure or function with
\\[idlwave-routine-info]. \\[idlwave-find-module] jumps to the
source file of a module. These commands know about system
routines, all routines in idlwave-mode buffers and (when the
idlwave-shell is active) about all modules currently compiled under
this shell. It also makes use of pre-compiled or custom-scanned
user and library catalogs many popular libraries ship with by
default. Use \\[idlwave-update-routine-info] to update this
information, which is also used for completion (see item 4).
3. Online IDL Help
---------------
\\[idlwave-context-help] displays the IDL documentation relevant
for the system variable, keyword, or routines at point. A single
key stroke gets you directly to the right place in the docs. See
the manual to configure where and how the HTML help is displayed.
4. Completion
----------
\\[idlwave-complete] completes the names of procedures, functions
class names, keyword parameters, system variables and tags, class
tags, structure tags, filenames and much more. It is context
sensitive and figures out what is expected at point. Lower case
strings are completed in lower case, other strings in mixed or
upper case.
5. Code Templates and Abbreviations
--------------------------------
Many Abbreviations are predefined to expand to code fragments and templates.
The abbreviations start generally with a `\\'. Some examples:
\\pr PROCEDURE template
\\fu FUNCTION template
\\c CASE statement template
\\sw SWITCH statement template
\\f FOR loop template
\\r REPEAT Loop template
\\w WHILE loop template
\\i IF statement template
\\elif IF-ELSE statement template
\\b BEGIN
For a full list, use \\[idlwave-list-abbrevs]. Some templates also
have direct keybindings - see the list of keybindings below.
\\[idlwave-doc-header] inserts a documentation header at the
beginning of the current program unit (pro, function or main).
Change log entries can be added to the current program unit with
\\[idlwave-doc-modification].
6. Automatic Case Conversion
-------------------------
The case of reserved words and some abbrevs is controlled by
`idlwave-reserved-word-upcase' and `idlwave-abbrev-change-case'.
7. Automatic END completion
------------------------
If the variable `idlwave-expand-generic-end' is non-nil, each END typed
will be converted to the specific version, like ENDIF, ENDFOR, etc.
8. Hooks
-----
Loading idlwave.el runs `idlwave-load-hook'.
Turning on `idlwave-mode' runs `idlwave-mode-hook'.
9. Documentation and Customization
-------------------------------
Info documentation for this package is available. Use
\\[idlwave-info] to display (complain to your sysadmin if that does
not work). For Postscript, PDF, and HTML versions of the
documentation, check IDLWAVE's homepage at URL
`http://github.com/jdtsmith/idlwave'.
IDLWAVE has customize support - see the group `idlwave'.
10.Keybindings
-----------
Here is a list of all keybindings of this mode.
If some of the key bindings below show with ??, use \\[describe-key]
followed by the key sequence to see what the key sequence does.

"Complete a function, procedure or keyword name at point.
This function is smart and figures out what can be completed
at this point.
- At the beginning of a statement it completes procedure names.
- In the middle of a statement it completes function names.
- After a `(' or `,' in the argument list of a function or procedure,
it completes a keyword of the relevant function or procedure.
- In the first arg of `OBJ_NEW', it completes a class name.
When several completions are possible, a list will be displayed in
the *Completions* buffer. If this list is too long to fit into the
window, scrolling can be achieved by repeatedly pressing
\\[idlwave-complete].
The function also knows about object methods. When it needs a class
name, the action depends upon `idlwave-query-class', which see. You
can force IDLWAVE to ask you for a class name with a
\\[universal-argument] prefix argument to this command.
See also the variables `idlwave-keyword-completion-adds-equal' and
`idlwave-function-completion-adds-paren'.
The optional ARG can be used to specify the completion type in order
to override IDLWAVE's idea of what should be completed at point.
Possible values are:
0 <=> query for the completion type
1 <=> `procedure'
2 <=> `procedure-keyword'
3 <=> `function'
4 <=> `function-keyword'
5 <=> `procedure-method'
6 <=> `procedure-method-keyword'
7 <=> `function-method'
8 <=> `function-method-keyword'
9 <=> `class'
As a special case, the universal argument C-u forces completion of
function names in places where the default would be a keyword.
Two prefix argument, C-u C-u, prompts for a regexp by which to limit
completion.
For Lisp programmers only:
When we force a keyword, optional argument MODULE can contain the module name.
When we force a method or a method keyword, CLASS can specify the class."
