EmEditor 26.4.0

What's new in 26.4.0

Today, we released EmEditor v26.4.
1. Edit Huge Files in Fast View Mode
In v26.3, we introduced Fast View mode, which opens a huge file almost instantly without loading the whole file into memory. Fast View mode was read-only, so to edit a huge file, you still had to switch to the normal mode and wait for the whole file to load.
In this version, Fast View mode supports editing. You can edit a huge file without loading it into memory: you can type, paste, Undo and Redo, Replace All, use multiple selections, and run most commands on the Insert, Convert, and Sort menus. The original file does not change until you save it.
1-1. Merge the Edits, or Save Only the Changes
When you save a huge file in Fast View mode, you can choose how to save it:
- Save and merge writes the edits into the file.
- Save only the changes to a diff file leaves the original file untouched and saves your edits in a separate diff file. The next time you open the file, EmEditor loads the diff file and restores your edits.
The diff file also keeps the positions of the lines, so the file opens instantly the next time. You can save, load, and discard diff files with the new Save Diff, Load Diff, and Discard Diff commands (File > Diff submenu of the All Commands menu).
1-2. CSV Editing, Workspaces, and the FAST Indicator
- Fast View mode now supports the CSV commands that change the document, including cell editing, Split Column, Combine Columns, Combine Lines, Hide Quotes Temporarily, Hide/Unhide Columns, Reset Column Width, and Align Left/Center/Right (Pro version only).
- Fast View documents are now included in workspaces, including their unsaved edits.
- The new FAST indicator on the status bar and a lightning bolt icon on the document tab show that a document is in Fast View mode. Double-click the indicator to switch between the normal mode and Fast View mode.
We also added the Fast View page to the Customize dialog box. The Minimum file size to enable Fast View mode setting has moved to this page from the Advanced page, and you can choose whether to prompt when saving a huge file, whether to save only the changes to a diff file, and whether to save the line positions of huge files. The page also lists the diff files so you can delete them.
1-3. Macros and Plug-ins
Most properties and methods of the Document and Selection objects that change the document can now be used in Fast View mode, and we added the GetFastViewDiffPath method to the Editor object. …
