;;; Commentary:
-;;; Visit a file using a form.
-;;;
-;;; === Naming conventions
-;;;
-;;; The names of all variables and functions start with 'forms-'.
-;;; Names which start with 'forms--' are intended for internal use, and
-;;; should *NOT* be used from the outside.
-;;;
-;;; All variables are buffer-local, to enable multiple forms visits
-;;; simultaneously.
-;;; Variable `forms--mode-setup' is local to *ALL* buffers, for it
-;;; controls if forms-mode has been enabled in a buffer.
-;;;
-;;; === How it works ===
-;;;
-;;; Forms mode means visiting a data file which is supposed to consist
-;;; of records each containing a number of fields. The records are
-;;; separated by a newline, the fields are separated by a user-defined
-;;; field separater (default: TAB).
-;;; When shown, a record is transferred to an Emacs buffer and
-;;; presented using a user-defined form. One record is shown at a
-;;; time.
-;;;
-;;; Forms mode is a composite mode. It involves two files, and two
-;;; buffers.
-;;; The first file, called the control file, defines the name of the
-;;; data file and the forms format. This file buffer will be used to
-;;; present the forms.
-;;; The second file holds the actual data. The buffer of this file
-;;; will be buried, for it is never accessed directly.
-;;;
-;;; Forms mode is invoked using M-x forms-find-file control-file .
-;;; Alternativily `forms-find-file-other-window' can be used.
-;;;
-;;; You may also visit the control file, and switch to forms mode by hand
-;;; with M-x forms-mode .
-;;;
-;;; Automatic mode switching is supported if you specify
-;;; "-*- forms -*-" in the first line of the control file.
-;;;
-;;; The control file is visited, evaluated using `eval-current-buffer',
-;;; and should set at least the following variables:
-;;;
-;;; forms-file [string]
-;;; The name of the data file.
-;;;
-;;; forms-number-of-fields [integer]
-;;; The number of fields in each record.
-;;;
-;;; forms-format-list [list]
-;;; Formatting instructions.
-;;;
-;;; `forms-format-list' should be a list, each element containing
-;;;
-;;; - a string, e.g. "hello". The string is inserted in the forms
-;;; "as is".
-;;;
-;;; - an integer, denoting a field number.
-;;; The contents of this field are inserted at this point.
-;;; Fields are numbered starting with number one.
-;;;
-;;; - a function call, e.g. (insert "text").
-;;; This function call is dynamically evaluated and should return a
-;;; string. It should *NOT* have side-effects on the forms being
-;;; constructed. The current fields are available to the function
-;;; in the variable `forms-fields', they should *NOT* be modified.
-;;;
-;;; - a lisp symbol, that must evaluate to one of the above.
-;;;
-;;; Optional variables which may be set in the control file:
-;;;
-;;; forms-field-sep [string, default TAB]
-;;; The field separator used to separate the
-;;; fields in the data file. It may be a string.
-;;;
-;;; forms-read-only [bool, default nil]
-;;; Non-nil means that the data file is visited
-;;; read-only (view mode) as opposed to edit mode.
-;;; If no write access to the data file is
-;;; possible, view mode is enforced.
-;;;
-;;; forms-multi-line [string, default "^K"]
-;;; If non-null the records of the data file may
-;;; contain fields that can span multiple lines in
-;;; the form.
-;;; This variable denotes the separator character
-;;; to be used for this purpose. Upon display, all
-;;; occurrencies of this character are translated
-;;; to newlines. Upon storage they are translated
-;;; back to the separator character.
-;;;
-;;; forms-forms-scroll [bool, default nil]
-;;; Non-nil means: rebind locally the commands that
-;;; perform `scroll-up' or `scroll-down' to use
-;;; `forms-next-field' resp. `forms-prev-field'.
-;;;
-;;; forms-forms-jump [bool, default nil]
-;;; Non-nil means: rebind locally the commands that
-;;; perform `beginning-of-buffer' or `end-of-buffer'
-;;; to perform `forms-first-field' resp. `forms-last-field'.
-;;;
-;;; forms-read-file-filter [symbol, default nil]
-;;; If not nil: this should be the name of a
-;;; function that is called after the forms data file
-;;; has been read. It can be used to transform
-;;; the contents of the file into a format more suitable
-;;; for forms-mode processing.
-;;;
-;;; forms-write-file-filter [symbol, default nil]
-;;; If not nil: this should be the name of a
-;;; function that is called before the forms data file
-;;; is written (saved) to disk. It can be used to undo
-;;; the effects of `forms-read-file-filter', if any.
-;;;
-;;; forms-new-record-filter [symbol, default nil]
-;;; If not nil: this should be the name of a
-;;; function that is called when a new
-;;; record is created. It can be used to fill in
-;;; the new record with default fields, for example.
-;;;
-;;; forms-modified-record-filter [symbol, default nil]
-;;; If not nil: this should be the name of a
-;;; function that is called when a record has
-;;; been modified. It is called after the fields
-;;; are parsed. It can be used to register
-;;; modification dates, for example.
-;;;
-;;; forms-use-text-properties [bool, see text for default]
-;;; This variable controls if forms mode should use
-;;; text properties to protect the form text from being
-;;; modified (using text-property `read-only').
-;;; Also, the read-write fields are shown using a
-;;; distinct face, if possible.
-;;; This variable defaults to t if running Emacs 19
-;;; with text properties.
-;;; The default face to show read-write fields is
-;;; copied from face `region'.
-;;;
-;;; forms-ro-face [symbol, default 'default]
-;;; This is the face that is used to show
-;;; read-only text on the screen.If used, this
-;;; variable should be set to a symbol that is a
-;;; valid face.
-;;; E.g.
-;;; (make-face 'my-face)
-;;; (setq forms-ro-face 'my-face)
-;;;
-;;; forms-rw-face [symbol, default 'region]
-;;; This is the face that is used to show
-;;; read-write text on the screen.
-;;;
-;;; After evaluating the control file, its buffer is cleared and used
-;;; for further processing.
-;;; The data file (as designated by `forms-file') is visited in a buffer
-;;; `forms--file-buffer' which will not normally be shown.
-;;; Great malfunctioning may be expected if this file/buffer is modified
-;;; outside of this package while it is being visited!
-;;;
-;;; Normal operation is to transfer one line (record) from the data file,
-;;; split it into fields (into `forms--the-record-list'), and display it
-;;; using the specs in `forms-format-list'.
-;;; A format routine `forms--format' is built upon startup to format
-;;; the records according to `forms-format-list'.
-;;;
-;;; When a form is changed the record is updated as soon as this form
-;;; is left. The contents of the form are parsed using information
-;;; obtained from `forms-format-list', and the fields which are
-;;; deduced from the form are modified. Fields not shown on the forms
-;;; retain their origional values. The newly formed record then
-;;; replaces the contents of the old record in `forms--file-buffer'.
-;;; A parse routine `forms--parser' is built upon startup to parse
-;;; the records.
-;;;
-;;; Two exit functions exist: `forms-exit' and `forms-exit-no-save'.
-;;; `forms-exit' saves the data to the file, if modified.
-;;; `forms-exit-no-save` does not. However, if `forms-exit-no-save'
-;;; is executed and the file buffer has been modified, Emacs will ask
-;;; questions anyway.
-;;;
-;;; Other functions provided by forms mode are:
-;;;
-;;; paging (forward, backward) by record
-;;; jumping (first, last, random number)
-;;; searching
-;;; creating and deleting records
-;;; reverting the form (NOT the file buffer)
-;;; switching edit <-> view mode v.v.
-;;; jumping from field to field
-;;;
-;;; As an documented side-effect: jumping to the last record in the
-;;; file (using forms-last-record) will adjust forms--total-records if
-;;; needed.
-;;;
-;;; The forms buffer can be in on eof two modes: edit mode or view
-;;; mode. View mode is a read-only mode, you cannot modify the
-;;; contents of the buffer.
-;;;
-;;; Edit mode commands:
-;;;
-;;; TAB forms-next-field
-;;; \C-c TAB forms-next-field
-;;; \C-c < forms-first-record
-;;; \C-c > forms-last-record
-;;; \C-c ? describe-mode
-;;; \C-c \C-k forms-delete-record
-;;; \C-c \C-q forms-toggle-read-only
-;;; \C-c \C-o forms-insert-record
-;;; \C-c \C-l forms-jump-record
-;;; \C-c \C-n forms-next-record
-;;; \C-c \C-p forms-prev-record
-;;; \C-c \C-r forms-search-backward
-;;; \C-c \C-s forms-search-forward
-;;; \C-c \C-x forms-exit
-;;;
-;;; Read-only mode commands:
-;;;
-;;; SPC forms-next-record
-;;; DEL forms-prev-record
-;;; ? describe-mode
-;;; \C-q forms-toggle-read-only
-;;; l forms-jump-record
-;;; n forms-next-record
-;;; p forms-prev-record
-;;; r forms-search-backward
-;;; s forms-search-forward
-;;; x forms-exit
-;;;
-;;; Of course, it is also possible to use the \C-c prefix to obtain the
-;;; same command keys as in edit mode.
-;;;
-;;; The following bindings are available, independent of the mode:
-;;;
-;;; [next] forms-next-record
-;;; [prior] forms-prev-record
-;;; [begin] forms-first-record
-;;; [end] forms-last-record
-;;; [S-TAB] forms-prev-field
-;;; [backtab] forms-prev-field
-;;;
-;;; For convenience, TAB is always bound to `forms-next-field', so you
-;;; don't need the C-c prefix for this command.
-;;;
-;;; As mentioned above (see `forms-forms-scroll' and `forms-forms-jump')
-;;; the bindings of standard functions `scroll-up', `scroll-down',
-;;; `beginning-of-buffer' and `end-of-buffer' can be locally replaced with
-;;; forms mode functions next/prev record and first/last
-;;; record.
-;;;
-;;; `local-write-file hook' is defined to save the actual data file
-;;; instead of the buffer data, `revert-file-hook' is defined to
-;;; revert a forms to original.
+;; Visit a file using a form.
