;;; Commentary:

;; Major mode for editing and validating BibTeX files.
;; Usage:
;; See documentation for function bibtex-mode (or type "\M-x describe-mode"
-;; when you are in bibtex-mode).
+;; when you are in BibTeX mode).
;; Todo:
;; Distribute texinfo file.
-;; Known Bugs:
-;; 1. using regular expressions to match the entire BibTeX entry dies
-;; on long entries (e.g. those containing abstracts) since
-;; the length of regular expression matches is fairly limited.
-;; 2. Calling bibtex-find-text in a string entry results in the
-;; error message "Can't find enclosing Bibtex field" instead of
-;; moving to the empty string. [reported by gernot@cs.unsw.oz.au]
-;; 3. Quotes inside quote-parenthesized fields (like
-;; `author = "Stefan Sch{\"o}f"') break bibtex-validate-buffer.
-;; Further, you must use braces here, if you want to set
-;; bibtex-maintain-sorted-entries to a non-nil value.

- use it for the name part of the key.
- 2. Change any substring found in `bibtex-autokey-name-change-strings'
- to the corresponding new one (see documentation of this variable
- for further detail).
- 3. For every of the first `bibtex-autokey-names' names in the
- \"name\" field, determine the last name.
- 4. From every last name, take at least `bibtex-autokey-name-length'
- characters (abort only after a consonant or at a word end).
- 5. Build the name part of the key by concatenating all abbreviated last
- names with the string `bibtex-autokey-name-separator' between
- any two.
- 6. Build the year part of the key by truncating the contents of the
- \"year\" field to the rightmost `bibtex-autokey-year-length'
- digits (useful values are 2 and 4).
- 7. For the title part of the key change the contents of the \"title\"
- field of the reference according to
- `bibtex-autokey-titleword-change-strings' to the corresponding
- new one (see documentation of this variable for further detail).
- 8. Abbreviate the result to the string up to (but not including) the
- first occurrence of a regexp matched by the items of
- `bibtex-autokey-title-terminators' and delete the first
- word if it appears in `bibtex-autokey-titleword-first-ignore'.
- Build the title part of the key by using at least the first
- `bibtex-autokey-titlewords' capitalized words from this
- abbreviated title. If the abbreviated title ends after maximal
- `bibtex-autokey-titlewords' + `bibtex-autokey-titlewords-stretch'
- capitalized words, all capitalized words from the abbreviated title
- are used.
- 9. For every used title word that appears in
- `bibtex-autokey-titleword-abbrevs' use the corresponding abbreviation
- (see documentation of this variable for further detail).
- 10. From every title word not generated by an abbreviation, take at
- least `bibtex-autokey-titleword-length' characters (abort only after
- a consonant or at a word end).
- 11. Build the title part of the key by concatenating all abbreviated
- title words with the string `bibtex-autokey-titleword-separator'
- between any two.
- 12. At least, to get the key, concatenate the name part, the year part
- and the title part with `bibtex-autokey-name-year-separator'
- between the name and the year if both are non-empty and
- `bibtex-autokey-year-title-separator' between the year and
- the title if both are non-empty."
-
+ 1. Use the value of `bibtex-autokey-prefix-string' as a prefix.
+ 2. If there is a non-empty author (preferred) or editor field,
+ use it as the name part of the key.
+ 3. Change any substring found in
+ `bibtex-autokey-name-change-strings' to the corresponding new
+ one (see documentation of this variable for further detail).
+ 4. For every of at least first `bibtex-autokey-names' names in
+ the name field, determine the last name. If there are maximal
+ `bibtex-autokey-names' + `bibtex-autokey-names-stretch'
+ names, all names are used.
+ 5. From every last name, take at least
+ `bibtex-autokey-name-length' characters (abort only after a
+ consonant or at a word end).
+ 6. Convert all last names according to the conversion function
+ `bibtex-autokey-name-case-convert'.
+ 7. Build the name part of the key by concatenating all
+ abbreviated last names with the string
+ `bibtex-autokey-name-separator' between any two. If there are
+ more names than are used in the name part, prepend the string
+ contained in `bibtex-autokey-additional-names'.
+ 8. Build the year part of the key by truncating the contents of
+ the year field to the rightmost `bibtex-autokey-year-length'
+ digits (useful values are 2 and 4). If the year field is
+ absent, but the entry has a valid crossref field and the

+ appear in `bibtex-autokey-titleword-ignore'.
+ Build the title part of the key by using at least the first
+ `bibtex-autokey-titlewords' words from this
+ abbreviated title. If the abbreviated title ends after
+ maximal `bibtex-autokey-titlewords' +
+ `bibtex-autokey-titlewords-stretch' words, all
+ words from the abbreviated title are used.
+11. Convert all used titlewords according to the conversion function
+ `bibtex-autokey-titleword-case-convert'.
+12. For every used title word that appears in
+ `bibtex-autokey-titleword-abbrevs' use the corresponding
+ abbreviation (see documentation of this variable for further
+ detail).
+13. From every title word not generated by an abbreviation, take
+ at least `bibtex-autokey-titleword-length' characters (abort
+ only after a consonant or at a word end).
+14. Build the title part of the key by concatenating all
+ abbreviated title words with the string
+ `bibtex-autokey-titleword-separator' between any two.
+15. At least, to get the key, concatenate
+ `bibtex-autokey-prefix-string', the name part, the year part
+ and the title part with `bibtex-autokey-name-year-separator'
+ between the name part and the year part if both are non-empty
+ and `bibtex-autokey-year-title-separator' between the year
+ part and the title part if both are non-empty. If the year
+ part is empty, but not the other two parts,
+ `bibtex-autokey-year-title-separator' is used as well.
+16. If the value of `bibtex-autokey-before-presentation-function'
+ is non-nil, it must be a function taking one argument. This
+ function is then called with the generated key as the
+ argument. The return value of this function (a string) is
+ used as the key.
+17. If the value of `bibtex-autokey-edit-before-use' is non-nil,
+ the key is then presented in the minibuffer to the user,
+ where it can be edited. The key given by the user is then
+ used."

"Major mode for editing BibTeX files.
-\\{bibtex-mode-map}
+To submit a problem report, enter \\[bibtex-submit-bug-report] from a
+BibTeX mode buffer. This automatically sets up a mail buffer with
+version information already added. You just need to add a description
+of the problem, including a reproducable test case and send the
+message.
+
+
+General information on working with BibTeX mode:
+
+You should use commands as \\[bibtex-Book] to get a template for a
+specific entry. You should then fill in all desired fields using
+\\[bibtex-next-field] to jump from field to field. After having filled
+in all desired fields in the entry, you should clean the new entry
+with command \\[bibtex-clean-entry].
+
+Some features of BibTeX mode are available only by setting variable
+bibtex-maintain-sorted-entries to t. However, then BibTeX mode will
+work with buffer containing only valid (syntactical correct) entries
+and with entries being sorted. This is usually the case, if you have
+created a buffer completely with BibTeX mode and finished every new
+entry with \\[bibtex-clean-entry].
+
+For third party BibTeX buffers, please call the function
+`bibtex-convert-alien' to fully take advantage of all features of
+BibTeX mode.
-A command such as \\[bibtex-Book] will outline the fields for a BibTeX book entry.
-The optional fields start with the string OPT, and thus ignored by BibTeX.
-The OPT string may be removed from a field with \\[bibtex-remove-OPT].
-\\[bibtex-kill-optional-field] kills the current optional field entirely.
-\\[bibtex-remove-double-quotes-or-braces] removes the double-quotes or
-braces around the text of the current field. \\[bibtex-empty-field]
-replaces the text of the current field with the default \"\" or {}.
+Special information:
-The command \\[bibtex-clean-entry] cleans the current entry, i.e. (i) removes
-double-quotes or braces from entirely numerical fields, (ii) removes
-OPT from all non-empty optional fields, (iii) removes all empty
-optional fields, and (iv) checks that no non-optional fields are empty.
+A command such as \\[bibtex-Book] will outline the fields for a BibTeX book entry.
+
+The optional fields start with the string OPT, and are thus ignored by BibTeX.
+Alternatives from which only one is required start with the string ALT.
+The OPT or ALT string may be removed from a field with \\[bibtex-remove-OPT-or-ALT].
+\\[bibtex-make-field] inserts a new field after the current one.
+\\[bibtex-kill-field] kills the current field entirely.
+\\[bibtex-yank] will yank the last recently killed field after the
+current field.
+\\[bibtex-remove-delimiters] removes the double-quotes or braces around the text of the current field.
+ \\[bibtex-empty-field] replaces the text of the current field with the default \"\" or {}.
+
+The command \\[bibtex-clean-entry] cleans the current entry, i.e. it removes OPT/ALT
+from all non-empty optional or alternative fields, checks that no required
+fields are empty, and does some formatting dependent on the value of
+bibtex-entry-format.
+Note: some functions in BibTeX mode depend on entries being in a special
+format (all fields beginning on separate lines), so it is usually a bad
+idea to remove `realign' from bibtex-entry-format.
Use \\[bibtex-find-text] to position the cursor at the end of the current field.
Use \\[bibtex-next-field] to move to end of the next field.
