Optimizations ============= - User Option: reftex-keep-temporary-buffers Non-`nil' means, keep buffers created for parsing and lookup. RefTeX sometimes needs to visit files related to the current document. We distinguish files visited for PARSING Parts of a multifile document loaded when (re)-parsing the document. LOOKUP BibTeX database files and TeX files loaded to find a reference, to display label context, etc. The created buffers can be kept for later use, or be thrown away immediately after use, depending on the value of this variable: `nil' Throw away as much as possible. `t' Keep everything. `1' Throw away buffers created for parsing, but keep the ones created for lookup. If a buffer is to be kept, the file is visited normally (which is potentially slow but will happen only once). If a buffer is to be thrown away, the initialization of the buffer depends upon the variable `reftex-initialize-temporary-buffers'. - User Option: reftex-initialize-temporary-buffers Non-`nil' means do initializations even when visiting file temporarily. When `nil', RefTeX may turn off find-file hooks and other stuff to briefly visit a file. When `t', the full default initializations are done (`find-file-hook' etc.). Instead of `t' or `nil', this variable may also be a list of hook functions to do a minimal initialization. - User Option: reftex-no-include-regexps List of regular expressions to exclude certain input files from parsing. If the name of a file included via `\include' or `\input' is matched by any of the regular expressions in this list, that file is not parsed by RefTeX. - User Option: reftex-enable-partial-scans Non-`nil' means, re-parse only 1 file when asked to re-parse. Re-parsing is normally requested with a `C-u' prefix to many RefTeX commands, or with the `r' key in menus. When this option is `t' in a multifile document, we will only parse the current buffer, or the file associated with the label or section heading near point in a menu. Requesting re-parsing of an entire multifile document then requires a `C-u C-u' prefix or the capital `R' key in menus. - User Option: reftex-save-parse-info Non-`nil' means, save information gathered with parsing in files. The file `MASTER.rel' in the same directory as `MASTER.tex' is used to save the information. When this variable is `t', - accessing the parsing information for the first time in an editing session will read that file (if available) instead of parsing the document. - exiting Emacs or killing a buffer in reftex-mode will cause a new version of the file to be written. - User Option: reftex-parse-file-extension File extension for the file in which parser information is stored. This extension is added to the base name of the master file. - User Option: reftex-allow-automatic-rescan Non-`nil' means, RefTeX may rescan the document when this seems necessary. Applies (currently) only in rare cases, when a new label cannot be placed with certainty into the internal label list. - User Option: reftex-use-multiple-selection-buffers Non-`nil' means use a separate selection buffer for each label type. These buffers are kept from one selection to the next and need not to be created for each use - so the menu generally comes up faster. The selection buffers will be erased (and therefore updated) automatically when new labels in its category are added. See the variable `reftex-auto-update-selection-buffers'. - User Option: reftex-auto-update-selection-buffers Non-`nil' means, selection buffers will be updated automatically. When a new label is defined with `reftex-label', all selection buffers associated with that label category are emptied, in order to force an update upon next use. When `nil', the buffers are left alone and have to be updated by hand, with the `g' key from the label selection process. The value of this variable will only have any effect when `reftex-use-multiple-selection-buffers' is non-`nil'.
