;;; Commentary:
;; Define filesets, which can be opened or saved with the power of one or
;; two mouse clicks only. A fileset is either a list of files, a file
;; pattern, a base directory and a search pattern (for files), or an
;; inclusion group (i.e. a base file including other files).
;; Usage:
;; 1. Put (require 'filesets) and (filesets-init) in your init file.
;; 2. Type ;; M-x filesets-edit or choose "Edit Filesets" from the menu.
;; 3. Save your customizations.
;; Caveat: Fileset names have to be unique.
;; Filesets.el adds a nifty filesets menu to your menubar. If you change
;; your filesets on the fly, don't forget to select "Save Filesets" from
;; the menu.
;; Pressing on the first item in the submenu will open all files at once.
;; Define your own function, e.g. browse-url, for opening a fileset's
;; files. Or define external viewers for opening files with other
;; programs. See `filesets-external-viewers'.
;; BTW, if you close a fileset, files, which have been changed, will
;; be silently saved. Change this behavior by setting
;; `filesets-save-buffer-fn'.
;;; Supported modes for inclusion groups (`filesets-ingroup-patterns'):
;; - Elisp
;; - Emacs-Wiki (simple names only)
;; - LaTeX
;;; Known bugs:
;;; To do:
;;- better handling of different customization scenarios
;; Data gathering should be better separated from building the menu
;; so that one could (1) use filesets without installing the menu
;; and (2) create new "frontends" to speedbar and others.
;; The functionality to call external viewers should be isolated in
;; an extra package and possibly integrated with the MIME
;; handling.

to ensure the use of the cache file, set this variable to t -- which is
the default for XEmacs prior to 21.5. If you want to change this value
put \"(setq filesets-menu-ensure-use-cached VALUE)\" into your startup

"Inclusion group definitions.
Define how to find included file according to a file's mode (being

CMD-DEF1 ...), CMD-DEF1 being a plist containing the fields :pattern
\(mandatory), :name, :get-file-name, :match-number, :scan-depth,
:preprocess, :case-sensitive.
File Pattern ... A regexp matching the file's name for which the
following rules should be applied.
Remove Duplicates ... If t, only the first occurrence of an included
file is retained. (See below for a full explanation.)
:name STRING ... This pattern's name.
:pattern REGEXP ... A regexp matching the command. This regexp has to
include a group that holds the name of the included file.
:get-file-name FUNCTION (default: `filesets-which-file') ... A function
that takes two arguments (the path of the master file and the name
of the included file) and returns a valid path or nil -- if the
subfile can't be found.
:match-number INTEGER (default: 1) ... The number of the match/group
in the pattern holding the subfile's name. 0 refers the whole
match, 1 to the first group.
:stubp FUNCTION ... If (FUNCTION MASTER INCLUDED-FILE) returns non-nil,
INCLUDED-FILE is a stub -- see below.
:stub-flag ... Files of this type are stubs -- see below.
:scan-depth INTEGER (default: 0) ... Whether included files should be
rescanned. Set this to 0 to disable re-scanning of included file.
:preprocess FUNCTION ... A function modifying a buffer holding the
master file so that pattern matching becomes easier. This is usually
used to narrow a buffer to the relevant region. This function could also
be destructive and simply delete non-relevant text.
:case-sensitive BOOLEAN (default: nil) ... Whether a pattern is
case-sensitive or not.
First, a stub is a file that shows up in the menu but will not be
included in an ingroup's file listing -- i.e. filesets will never
operate on this file automatically. Secondly, in opposition to normal
files stubs are not scanned for new inclusion groups. This is useful if
you want to have quick access to library headers.
In the menu, an asterisk is appended to the stub's name.
Remove Duplicates:
E.g. File A and file B refer to file X; X refers to A. If
you choose not to remove duplicates the tree would look like:
M + A - X - A ...
B - X - A ...
As you can see, there is some chance that you run in circles.
Nevertheless, up to some degree this could still be what you want.
With duplicates removed, it would be:
M + A - X

"Fileset definitions.
A fileset is either a list of files, a file pattern, a base directory
and a search pattern (for files), or a base file. Changes to this
variable will take effect after rebuilding the menu.
Caveat: Fileset names have to be unique.
Example definition:
'\(\(\"My Wiki\"
\(:ingroup \"~/Etc/My-Wiki/WikiContents\"))
\(\"My Homepage\"
\(:pattern \"~/public_html/\" \"^.+\\\\.html$\")
\(:open filesets-find-file))

`filesets-data' is a list of (NAME-AS-STRING . DEFINITION), DEFINITION
being an association list with the fields:
:files FILE-1 .. FILE-N ... a list of files belonging to a fileset
:ingroup FILE-NAME ... an inclusion group's base file.
:tree ROOT-DIR PATTERN ... a base directory and a file pattern
:pattern DIR PATTERN ... a base directory and a regexp matching
files in that directory. Usually,
PATTERN has the form '^REGEXP$'. Unlike
:tree, this form does not descend
recursively into subdirectories.
:filter-dirs-flag BOOLEAN ... is only used in conjunction with :tree.
:tree-max-level INTEGER ... recurse into directories this many levels
\(see `filesets-tree-max-level' for a full explanation)
:dormant-flag BOOLEAN ... non-nil means don't show this item in the
menu; dormant filesets can still be manipulated via commands available
from the minibuffer -- e.g. `filesets-open', `filesets-close', or
:dormant-p FUNCTION ... a function returning :dormant-flag
:open FUNCTION ... the function used to open file belonging to this
fileset. The function takes a file name as argument
:save FUNCTION ... the function used to save file belonging to this
fileset; it takes no arguments, but works on the current buffer.
Either :files, :pattern, :tree, or :ingroup must be supplied. :files
overrules :tree, :tree overrules :pattern, :pattern overrules :ingroup,
i.e. these tags are mutually exclusive. The fields :open and :save are
In conjunction with the :tree tag, :save is void. :open refers to the
function used for opening files in a directory, not for opening the
directory. For browsing directories, `filesets-browse-dir-function' is used.
Before using :ingroup, make sure that the file type is already
defined in `filesets-ingroup-patterns'."

Filesets has detected that you were using an older version before,
which requires some manual updating. Type 'y' for editing the startup
file now.
The layout of `filesets-data' has changed. Please delete your cache file
and edit your startup file as shown below:
1. `filesets-data': Edit all :pattern filesets in your startup file and
transform all entries as shown in this example:
\(\"Test\" (:pattern \"~/dir/^pattern$\"))
--> \(\"Test\" (:pattern \"~/dir/\" \"^pattern$\"))
2. `filesets-data': Change all occurrences of \":document\" to \":ingroup\":
\(\(\"Test\" \(:document \"~/dir/file\"))
--> \(\(\"Test\" \(:ingroup \"~/dir/file\"))
3. `filesets-subdocument-patterns': If you already modified the variable
previously called `filesets-subdocument-patterns', change its name to
4. `filesets-menu-cache-contents': If you already modified this
variable, change the entry `filesets-subdocument--cache' to
5. Type M-x filesets-update-cleanup and restart Emacs.
We apologize for the inconvenience."))
