Directory-wide File Variables

You can put file variables in a special file named .epsilon_vars. Such settings apply to all files in its directory. In an .epsilon_vars file, lines starting with # are comments. It contains one or more sections. Within each section, settings in it appear one per line, with a setting name, a colon, and a value. Each section begins with a line that says which files or modes it affects:

# Special settings for this directory.
Extensions: .r*
mode: Perl

Modes: Perl|Python
tab-size: 3

Modes: C
tab-size: 5
indent-tabs-mode: nil

Filenames: buildfile*|build[1-2]*|*build.dat
mode: makefile

The Modes, Extensions, and Filenames lines use a file wildcard pattern. It can use | for alternation, ? to match a single character or * to match any number, or character ranges like [a-z]. Epsilon will apply the settings in the section that follows only if the original file's extension, mode, or basename matches the pattern. This example says that all files with an extension like .r or .rxx or .ram in that directory should use Perl mode, and sets the tab size to 3 for Perl or Python files, and 5 for C files, also turning off using Tab characters to indent. Then it says that files whose names start with buildfile, build1, or build2, or end in build.dat, should use Makefile mode.

Epsilon decides which sections to use before applying the settings, so an .rxx file forced to Perl mode by the above example file won't get a tab size of 3 unless you add a tab-size: 3 line to its Extensions section. Also note that "mode:" sets a file's mode; "Modes:" begins a section for a specific mode. File variables in an individual file take precedence over those in an .epsilon_vars file.
