New in Version 21.7
May 11, 2022
New General Features
- The new version displays file comparison results in one vertically split window by default when you select the Compare or Compare with Options command. The previously used tiled window display is still possible by setting options.
- The new version will keep the scroll position bottom when the file is reloaded if the scroll position was bottom before reloaded.
- When the Detect All option is set in the File page of configuration properties, the detected encoding was unsupported on Windows (such as VISCII), the new version will continue to open the file as the system default encoding and show a notification.
- Improved URI highlighting.
- Improved line selections in CSV selection mode.
- Changed the default style of Horizontal Grid from Dotted Lines to Normal, and optimized the drawing speed for Vertical Separators.
- Changed the default value for the End Indent in a regular expression in some configurations including C++.
- Supported Bulk Replace All in the Batch Replace dialog box. Bulk Replace All searches the document simultaneously for all search strings while Batch Replace All searches the document for one search string at a time and repeats the search for each search term. Bulk Replace All works much faster than Batch Replace All. See Difference between Batch Replace All and Bulk Replace All for more information.

Difference between Batch Replace All and Bulk Replace All
Batch Replace All searches a whole document for one string at a time, and repeats this procedure for the number of search strings. Bulk Replace All searches for all search strings simultaneously. The difference may lead to different results if search/replace string pairs contain, for instance:
1 → 5
2 → 4
4 → 2
5 → 1
and if the source document is:
[1,2,3,4,5]
In this case, if Batch Replace All is used, EmEditor will replace 1 with 5 for the whole document first, and then will replace 2 with 4. At this point, the source document becomes:
[5,4,3,4,5]
Next, when it replaces 4 with 2, note that it will replace two 4’s (the second and fourth numbers). Lastly, when it replaces 5 with 1, it will replace two 5’s (the first and last numbers). Thus, the result will be:
[1,2,3,2,1]
If the new Bulk Replace All is used, EmEditor will replace all strings simultaneously. Therefore, the result will be:
[5,4,3,2,1]
as you expect.
Bulk Replace All will replace much faster than Batch Replace All. In our test, Bulk Replace All completed 6310 times faster than Batch Replace All when one million search/replace pairs existed (See test results).
Bulk Replace All does not support regular expressions, number ranges, or strings including newlines.
