Buffer and File Enhancements in Epsilon 13

• Epsilon now supports many more "file variables", special lines in a file that set its mode, tab size, or other settings. You can now create directory-wide settings, setting up a special file that says, for instance, that all C++ files in that directory should be indented using spaces only, not tabs. And Epsilon now recognizes the syntax used by the Vi/Vim family of editors for file variables.

• You can set completion to skip over files whose names match a certain pattern using the new ignore-file-pattern and ignore-file-basename variables. By default, completion ignores files and directories starting with a period character. If these rules eliminate all possible matches, Epsilon suspends them for that completion.

• To autodetect the correct line translation rule (Unix vs. Windows vs. Macintosh line endings), Epsilon now looks at a much larger section of each file, resulting in improved accuracy, and explains why it chose a particular translation rule.

• You can now set line translation rules for new remote files on a per-system basis, using host-specific variables.

• Epsilon now recognizes a new write-line-translate file variable, which may be used to force all files in a certain directory to be saved in Unix, Windows, Binary or Mac format. (13.01)

• You can now easily set Epsilon to prevent saving a file with an unterminated line at the end, either for all files or only for specific modes, using the default-add-final-newline variable.

• When auto-saving is enabled, Epsilon now auto-saves based on idle time as well as character counts, no longer displays a message each time it auto-saves, and cleans up old auto-save files automatically, among other enhancements. The want-auto-save variable has new bits to configure some of the new features, and there are new variables auto-save-biggest-file and auto-save-idle-seconds.

• File pattern matching on ** can now be set to skip directories whose names match a pattern. Under Windows, you can restrict completion and other matching on UNC file names to particular domains.

• Epsilon for Windows can now be set to accept Cygwin-style file names on its command line.

• Many dired subcommands that ask for confirmation now recognize an "All" option that skips the warning for the remaining files in a group. The dired command now displays very large files properly. On long multi-directory listings, it shows its progress earlier. And under Windows, the dired-layout variable can now be set to use an alternative date format; its new default setting makes Epsilon display the read-only flag of each file.

• Bufed has a new m subcommand that toggles whether modified buffers appear first in its listing (13.00), and the bufed-show-absolute-path variable accepts new values to make it always display the directory portion of each file name (13.07).

• The new copy-file-name command on Ctrl-c Alt-n puts the current file name on the clipboard.

• Epsilon's warning that a file has changed on disk now includes an option to display a visual-diff listing of the differences.

• The commands insert-file and compare-to-prior-version now work with URLs as well as local files. (13.03)

• The new switch-buffers-options variable lets you customize the buffer ordering of Ctrl-Tab. (13.04)

• The new yank-options variable changes how yanking an absolute path name at a file name prompt works. (13.04)

• Epsilon for Windows now has much better support for NTFS junctions and symbolic links. Dired will show their destinations, and ** file syntax will follow them while guarding against loops, as under Unix. (13.08)

• Dired now includes a Shift-G subcommand that runs a flavor of grep to select files for an operation based on their content. For instance, it's now easy to move only those files in a directory that don't contain the word "approved" into a separate directory. The new dired keys Alt-[ and Alt-] move by such markings or by subdirectories (in a multi-directory listing). (13.00) The new F subcommand searches with a restriction to only match file names. (13.04) Dired's A subcommand to set attributes now works on scp files. (13.05)
