preserve-filename-case: preference variable

Default value: 0

Bits in this variable control whether Epsilon displays certain uppercase file names as lowercase, whether uppercase letters in file names are carried over to their corresponding buffer names, and various related settings.

Set the 1 bit to tell Epsilon to use the case of file names exactly as retrieved from the operating system. By default, on case-insensitive file systems like VFAT or NTFS, Epsilon changes all-uppercase file names like WIN.INI to lowercase like win.ini. It never alters the case of a file name that contains any lowercase letters. (Epsilon never changes the case of filenames under Unix regardless of this bit.)

By default, the buffer name Epsilon chooses when you read a file uses only lowercase letters, even if the corresponding file name uses uppercase. Set the 2 bit if you want buffer names to match the case of their file names. (Setting this variable doesn't rename existing buffers.)

Set the 4 bit if you want Epsilon to fold case when comparing buffer names during completion and grep. This and the following flag are most useful when combined with the previous flag.

Set the 8 bit if you want sorting by buffer or file name in a bufed listing to fold case.

Set the 16 bit to make Epsilon for Mac OS treat file names as case-sensitive (instead of the default, case-preserving). Epsilon will consider FILE and File to be two different files.

Set the 32 bit to make Epsilon for Linux or FreeBSD treat file names as case-preserving (instead of the default, case-sensitive). Epsilon will treat FILE and File as two names for the same file.
