;;; Commentary:
|
||
|
||
;; IDLWAVE enables feature-rich development and interaction 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.

|
||
;; 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
|
||
;; a pre-selected region.
|
||
;;
|
||
;; When forcing completion of method keywords, the initial
|
||
;; query for a method has multiple entries for some methods. Would
|
||
;; be too difficult to fix this hardly used case.

|

|
||
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').

|
||
"Major mode for editing IDL source files (version 5.7_22).
|
||
|
||
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 routine at point. A single
|
||
key stroke gets you directly to the right place in the docs. The
|
||
HTML help files package must be installed for this to work -- check
|
||
the IDLWAVE webpage for the correct package for your version. 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 `http://idlwave.org'.
|
||
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.

This function is smart and figures out what can be completed

- 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."
