Iedit - Edit multiple regions simultaneously
This package is an Emacs minor mode and allows you to edit one occurrence of some text in a buffer or region, and simultaneously have other occurrences edited in the same way, with visual feedback as you type.
Normal scenario of Iedit mode is like:
- Highlight certain contents - by press C-; All occurrences of a symbol, string or a rectangle in the buffer or a region 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
This package also provides rectangle support with visible rectangle highlighting, which is similar with cua mode rectangle support, but still quite different.
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 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.
