opening brace or paren and key. Simplify regexp.
(bibtex-type-in-head, bibtex-key-in-head): Decrement.
(bibtex-mode): Use new function run-with-idle-timer instead of
auto-save-hook for periodically parsing keys.
(bibtex-mode-syntax-table, bibtex-autokey-name-change-strings,
bibtex-autokey-titleword-change-strings): Support non-escaped
double-quoted characters (as with german styles).
(bibtex-field-string-quoted): Disallow lines like
author = "Stefan Sch"of"
until BibTeX supports them.
functionality of bibtex-pop-previous and bibtex-pop-next. Now,
bibtex-pop moves to the end of field after the pop. Concatenated
strings are now handled correctly. Delimiters are not added to
non-delimited entries. Changed occurences of
bibtex-text-in-cfield to bibtex-text-in-field.
(bibtex-pop-previous, bibtex-pop-next): Call bibtex-pop.
(bibtex-complete-string): Fixed bug that removed delimiters
around the following field if current field is already
undelimited on completion.
(bibtex-complete-string, bibtex-remove-double-quotes-or-braces):
Only remove delimiters if field text is not concatenated.
(bibtex-font-lock-keywords): Use the same regexps used
in all other places of bibtex.el to parse the buffer.
(bibtex-mode): Changed the definition of font-lock-defaults,
so that quote-delimited entries aren't fontified as strings anymore.
(bibtex-parse-keys): Changed the regexp used for finding crossref entries.
(bibtex-field-const, bibtex-reference-key): Fixed the regexp
to match more of the characters allowed here by BibTeX/LaTeX.
(bibtex-field-name): Made it less restrictive.
(bibtex-field-string): Changed so that quote-delimited entries
with quotes inside aren't a problem anymore. Changed nesting
level of braces in entries to support three inner braces.
(bibtex-validate-buffer): By giving an optional argument, the
user can now let it not validate the whole buffer, but only
the portion starting at point. Small modification in strategy
used to find next entry.
(bibtex-print-help-message): Ignore case in field name when
searching for help text.
(bibtex-submit-bug-report): New function.
changed autofill policy of emacs-19.30 (uses now fill-prefix
instead of indent-line-function).
(bibtex-indent-line-function): Removed (not used any more).
(bibtex-make-field): Was broken when called
non-interactively.
(bibtex-make-field): Point is now placed on closing
brace or quote (suggested by Karl Eichwalder <ke@ke.Central.DE>).
(bibtex-clean-entry): Comma after last field isn't
deleted anymore (new standard in BibTeX 0.99 and 1.xx).
(bibtex-enclosing-reference-maybe-empty-head): Works with entries
with comma after last field.
(bibtex-reference): Permits entries with comma after last field.
(bibtex-font-lock-keywords): Enhanced to support new field-name
characters (suggested by Martin Maechler
<maechler@stat.math.ethz.ch>).
(bibtex-field-name): Now numbers (not as the first sign), dashes,
and underscores are allowed (suggested by Martin Maechler
<maechler@stat.math.ethz.ch> and Oren Patashnik
<opbibtex@labrea.Stanford.EDU>).
(bibtex-make-field): Was broken on lines containing
non-parenthesized entries (reported by Karl Eichwalder
<ke@ke.Central.DE>).
(bibtex-validate-buffer): Changed so that preamble
references are ignored (same as string entries) (reported by
Martin Maechler <maechler@stat.math.ethz.ch>).
(bibtex-enclosing-reference-maybe-empty-head):
New function to be used in case reference head may be empty.
(bibtex-clean-entry, bibtex-pop-previous, bibtex-pop-next): Uses
now bibtex-enclosing-reference-maybe-empty-head.
(bibtex-mode): Added support for font-lock mode.
(bibtex-font-lock-keywords): New variable with font-lock keywords
for BibTeX mode.
(bibtex-make-optional-field): Not longer interactive
(suggested by Karl Eichwalder <karl@pertron.central.de>).
(bibtex-maintain-sorted-entries): Set to nil, since it
requires more user attention and more restricted files to have
this set to t.
(bibtex-maintain-sorted-entries,
bibtex-sort-ignore-string-entries): Made buffer local, since it
may depend on the buffer which preferences to use.
(bibtex-validate-buffer): Looking for correct sort order only when
bibtex-maintain-sorted-entries is non-nil.
Put a comment in the `KNOWN BUGS' section about the
quote-inside-quotes problem.
(whole file): Changed string `true' in some documentation strings
to `non-nil' (e.g. `if variable has a true/non-nil value').
(bibtex-mode-map): Changed `move/edit' to `bibtex-edit'.
(bibtex-sort-entries): Now works correctly with
`@String' entries inside BibTeX files (i.e. after the occurence of
other references).
(bibtex-validate-buffer): Inserted code which looks if entries are
balanced (a single non-escaped quote inside braces was not
detected till now, but bibtex-sort-entries stumbles about it).
(bibtex-entry): bibtex-move-outside-of-entry is only
called when bibtex-maintain-sorted-entries is nil (otherwise
bibtex-find-entry-location determines the correct location).
(bibtex-find-entry-location): Now uses binary search. As before,
it assumes that the buffer is sorted without duplicates (but as
before it is only called when bibtex-maintain-sorted-entries is
t). Ignores `@String' entries if told so via variable
bibtex-sort-ignore-string-entries.
(bibtex-clean-entry): Respect
bibtex-maintain-sorted-entries when inserting autokey.
(bibtex-validate-buffer): Searching whole buffer for duplicates
and correct order is now done directly instead of calling
bibtex-find-entry-location (since this is to be reprogrammed to
use a binary search instead a sequential one).
(bibtex-parse-keys): May now be called with an
optional parameter which (if t) tells bibtex-parse-keys that it
should abort if input is pending.
(bibtex-mode): The instance of bibtex-parse-keys called in
auto-save-mode-hook is now called with this new parameter set to
t, so an auto-save caused by exceeding auto-save-interval is now
aborted immediately if user is still typing.
(bibtex-print-help-message, bibtex-clean-entry): Use
now constant strings instead of custom ones.
(bibtex-clean-entry): Changed the call of
bibtex-enclosing-reference to a more specific call so entries
without a key (here allowed) can be handled.
(bibtex-reference-key): Cleared off parentheses (caused string
entries enclosed by parentheses instead of braces to be not added
to bibtex-completion-candidates).
(bibtex-complete-string): Made it use bibtex-string.
(bibtex-keys,
bibtex-buffer-last-parsed-for-keys-tick): New buffer-local
variables to make parsing of BibTeX buffer for reference keys
(needed by TAB completion in minibuffer when entering key) more
occasional.
(bibtex-parse-keys): New function to parse for keys (functionality
was partially included in bibtex-entry).
(bibtex-entry): Changed to use bibtex-parse-keys.
(bibtex-mode): Installs bibtex-parse-keys as an
auto-save-mode-hook, so whole buffer is parsed at most when it is
autosaved.
(bibtex-clean-entry): Calls bibtex-parse-keys on the new entry, so
bibtex-keys remains consistent for new entries that are finished
by calling this function (most should).
(bibtex-inside-field): Be independent on current
setting of bibtex-field-right-delimiter (allows more intermixing
between quotes and braces).
(bibtex-make-field): Last change didn't make it work correctly
when called non-interactively by bibtex-entry (fixed).
Changed almost all occurences of buffer-substring to
buffer-substring-no-properties..
(bibtex-find-entry-location, bibtex-clean-entry):
Added support to handle invalidate buffers in a more friendly manner.
(bibtex-make-field): Changed to be called either interactively with a
string (field name) or from Lisp with a list of two strings (FIELDNAME
COMMENT).
Support both kind of delimiters (braces or quotes) regardless of the
value of bibtex-field-left-delimiter and bibtex-field-right-delimiter.
(bibtex-field-left-delimiter, bibtex-field-right-delimiter):
Made buffer-local.
(bibtex-beginning-of-entry): At the beginning of an
entry, leave point at the beginning of that entry instead of
moving to the beginning of the previous one.
(bibtex-end-of-entry): Outside an entry, now move to the end of
the *previous* entry (i.e. bibtex-beginning-of-entry and
bibtex-end-of-entry are now idempotent).
(bibtex-sort-entries, bibtex-clean-entry): Removed now obsolete
calls of bibtex-beginning-of-entry just before calls to
bibtex-end-of-entry.
(bibtex-clean-entry): Minor change to adapt to new behavior of
bibtex-beginning-of-entry.
(sort-subr): Don't call autload for this--that's done in loaddefs.el.
(bibtex-mode): Add autoload cookie.
Changed keybinding for bibtex-print-help-message
(from \C-ch to \C-c?). Therefore, describe-mode is not longer on
\C-c?. Also, changed prefix \C-cn for bibtex-narrow functions to
\C-c\C-r.
(bibtex-string-files): Changed documentation.
(bibtex-mode-map): Inscriptions of menu bar changed from "Entry
Types" to "Entry-Types" and "Bibtex Edit" to "BibTeX-Edit".
(bibtex-string-files): Changed documentation.
(bibtex-mode): If environment variable BIBINPUTS isn't defined,
string files are searched in the current directory.
(bibtex-completion-candidates): Now buffer-local to allow
evaluation of different bibtex-string-files in different buffers.
(bibtex-autokey-edit-before-use, bibtex-clean-entry): New variable
that determines, if the user is allowed to edit auto-generated
reference keys before they are used.
(bibtex-generate-autokey, bibtex-clean-entry): New function to
generate an autokey if necessary.
(bibtex-autokey-names, bibtex-autokey-name-change-strings,
bibtex-autokey-name-length, bibtex-autokey-name-separator,
bibtex-autokey-year-length, bibtex-autokey-titlewords,
bibtex-autokey-title-terminators,
bibtex-autokey-titlewords-stretch,
bibtex-autokey-titleword-first-ignore,
bibtex-autokey-titleword-abbrevs,
bibtex-autokey-titleword-change-strings,
bibtex-autokey-titleword-length,
bibtex-autokey-titleword-separator,
bibtex-autokey-name-year-separator,
bibtex-autokey-year-title-separator): New variables related to
bibtex-generate-autokey.
(bibtex-find-entry-location): Optional second parameter maybedup
to tell it that entering a duplicate entry isn't to report by an
error but by the return value of the function (necessary for
bibtex-clean-entry to find the correct position of an entry with
an autogenerated key without disturbing the user with unwanted
messages).
(bibtex-help-message): New variable to avoid printing of help
messages in the echo area.
(assoc-of-regexp): New function to match an alist of regexps.
(bibtex-string-files, bibtex-completion-candidates, bibtex-mode):
New variables to allow bibtex-complete-string to work on strings
initialized from a variable and from @String definitions in a list
of files, too.
(bibtex-predefined-strings, bibtex-entry-field-alist): Changed to
user options.
(bibtex-mode): Changed doc string.
(many functions and variables): Changed documentation strings of
variables and functions to hold a complete sentence in the first
line.
(bibtex-print-help-message): Now line dependent and reports if it
is called outside a BibTeX field.
(validate-bibtex-buffer): Completely rewritten to validate, if
buffer is syntactically correct.
(find-bibtex-duplicates): Moved into validate-bibtex-buffer.
(ispell-abstract, bibtex-ispell-abstract, ispell-bibtex-entry,
bibtex-ispell-entry, beginning-of-bibtex-entry,
bibtex-beginning-of-entry, end-of-bibtex-entry,
bibtex-end-of-entry, hide-bibtex-entry-bodies,
bibtex-hide-entry-bodies, narrow-to-bibtex-entry,
bibtex-narrow-to-entry, sort-bibtex-entries, bibtex-sort-entries,
validate-bibtex-buffer, bibtex-validate-buffer,
find-bibtex-entry-location, bibtex-find-entry-location): All
interactive functions are renamed, so that any interface function
begins with "bibtex-". Mapping:
ispell-abstract --> bibtex-ispell-abstract
ispell-bibtex-entry --> bibtex-ispell-entry
beginning-of-bibtex-entry --> bibtex-beginning-of-entry
end-of-bibtex-entry --> bibtex-end-of-entry
hide-bibtex-entry-bodies --> bibtex-hide-entry-bodies
narrow-to-bibtex-entry --> bibtex-narrow-to-entry
sort-bibtex-entries --> bibtex-sort-entries
validate-bibtex-buffer --> bibtex-validate-buffer
find-bibtex-entry-location --> bibtex-find-entry-location
(bibtex-maintain-sorted-entries,
bibtex-sort-ignore-string-entries): Default is now t.
(bibtex-complete-string): String list is built from additional
string list bibtex-predefined-string and current strings in file.
(string-equalp): Deleted and substituted by string-equal.
(assoc-string-equalp): Renamed to assoc-ignore-case.
(bibtex-entry): Reference key can be entered with completion. All
reference keys that are defined in buffer and all labels that
appear in crossreference entries are object to completion.
(Entry types): Changed order of entries in menu "entry types".
(bibtex-entry-field-alist): Changed order of entries slightly to
be more conform with standard BibTeX style layouts.
(bibtex-mode-map): Uniform keybindings for \C-c\C-e prefix (often
used types on control keys, sometimes used types on normal keys,
rarely used types on shift keys, almost never used types on meta
keys).
(bibtex-mode-map): Function narrow-to-bibtex-entry and counterpart
widen and function hide-bibtex-entry-bodies and counterpart
show-all bounded to appropriate local keys.
(bibtex-abbrev-table): Deleted
(bibtex-current-entry-label, put-string-on-kill-ring): Deleted
(AUCTeX provides all the functionality needed for citation
completion).
(bibtex-enclosing-reference, bibtex-pop-previous, bibtex-pop-next,
bibtex-clean-entry): Hacked for speed (bibtex-pop-previous and
bibtex-pop-next were to slow for larger BibTeX files).
(bibtex-pop-previous, bibtex-pop-next): Delimiters from previous
or next entry are changed to actual delimters if necessary.
(bibtex-entry): Fixed bug (False entry wasn't reported in error
message if bibtex-entry was called with undefined reference name).
(bibtex-entry-field-alist, bibtex-entry, bibtex-make-field,
bibtex-next-field, bibtex-clean-entry): Every reference entry now
contains a comment in addition to the name of the reference. This
comment appears in the echo area if you start editing that field
(after calling bibtex-next-field).
(bibtex-include-OPTcrossref, bibtex-entry): Changed
bibtex-include-OPTcrossref from single boolean variable to hold a
list of reference names which should have a crossref field.
(bibtex-complete-word): New function, which completes word
fragment before point to the longest prefix of predefined strings
in the buffer in the same way that ispell-complete-word operates
for words found in the dictionary.
(bibtex-reference-head): Start of bibtex-reference-head changed
from "^[ \t]*\\(" to "^\\( \\|\t\\)*\\(" (bibtex-pop-previous and
bibtex-pop-next didn't work, probably due to a bug in
re-search-forward).
(several functions): Added support for {} as field delimiters
(better than '"' for accented characters.
(bibtex-clean-entry): If optional field crossref is empty or
missing, former optional fields (if bibtex-include-OPTcrossref was
t) are necessary again. bibtex-clean-entry complains if they are
empty but not if they are missing, so you can intenionally omit
them, e. g. for a pseudo @Journal entry (needed for
crossreferences) made out of an @article with missing non-optional
fields.
Menu bar entries aren't centered anymore.
