This gives you the ;; effect of a temporary `keep-lines' or `occur'. To get this effect, hit C-' ;; when in Iedit mode - it toggles hiding non-matching lines. ;; ;; Renaming refactoring is convenient in Iedit mode ;; ;; - The symbol under point is selected as occurrence by default and only ;; complete symbols are matched ;; - With digit prefix argument 0, only symbols in current function are matched ;; - Restricting symbols in current region can be done by pressing C-; again ;; - Last renaming refactoring is remembered and can be applied to other buffers ;; later ;; ;; There are also some other facilities you may never think about. Refer to the ;; document of function `iedit-mode' (C-h f iedit-mode RET) for more details. ;; The code was developed and fully tested on Gnu Emacs 24.0.93, partially ;; tested on Gnu Emacs 22.

This command behaves differently, depending on the mark, point, prefix argument and variable `iedit-transient-mark-sensitive'. If Iedit mode is off, turn Iedit mode on. When Iedit mode is turned on, all the occurrences of the current region in the buffer (possibly narrowed) or a region are highlighted. If one occurrence is modified, the change are propagated to all other occurrences simultaneously. If region is not active, `iedit-default-occurrence' is called to get an occurrence candidate, according to the thing at point. It might be url, email address, markup tag or current symbol(or word) . In the above two situations, with digit prefix argument 0, only occurrences in current function are matched. This is good for renaming refactoring in programming. You can also switch to Iedit mode from isearch mode directly. The current search string is used as occurrence. All occurrences of the current search string are highlighted. With an universal prefix argument, the occurrence when Iedit mode is turned off last time in current buffer is used as occurrence. This is intended to recover last Iedit mode which is turned off. If region active, Iedit mode is limited within the current region. With repeated universal prefix argument, the occurrence when Iedit mode is turned off last time (might be in other buffer) is used as occurrence. If region active, Iedit mode is limited within the current region. With digital prefix argument 1, Iedit mode is limited on the current symbol or the active region, which means just one instance is highlighted. This behavior serves as a start point of incremental selection work flow. If Iedit mode is on and region is active, Iedit mode is restricted in the region, e.g. the occurrences outside of the region is excluded. If Iedit mode is on and region is active, with an universal prefix argument, Iedit mode is restricted outside of the region, e.g. the occurrences in the region is excluded.

Normal scenario of Iedit mode is like: - Highlight certain contents - by press C-; (The default key binding) All occurrences of a symbol, string or a region in the buffer may be highlighted corresponding to current mark, point and prefix argument. Refer to the document of `iedit-mode' for details. - Edit one of the occurrences The change is applied to other occurrences simultaneously. - Finish - by pressing C-; again You can also use Iedit mode as a quick way to temporarily show only the buffer lines that match the current text being edited. This gives you the effect of a temporary `keep-lines' or `occur'. To get this effect, hit C-' when in Iedit mode - it toggles hiding non-matching lines. Renaming refactoring is convinient in Iedit mode - The symbol under point is selected as occurrence by default and only complete symbols are matched - With digit prefix argument 0, only occurrences in current function are matched - Restricting symbols in current region can be done by pressing C-; again - Last renaming refactoring is remembered and can be applied to other buffers later - Restricting the search area to just the current line can be done by pressing M-I. - Restricting the search area to the lines near the current line can be done by pressing M-{ and M-}. These will expand the search region one line at a time from the top and bottom. Add a prefix argument to go the opposite direction. Iedit-rectangle-mode provides rectangle support with *visible rectangle* highlighting, which is similar with cua mode rectangle support. But it's lighter weight and uses iedit mechanisms. There are also some other facilities you may never think about.
