Identifiers
Identifiers in EEL consist of a letter or the underscore character "_", followed by any number of letters, digits, or
underscore characters. Upper case and lower case characters are
distinct to the compiler, so Ab and ab are different
identifiers. When you load an identifier into Epsilon, Epsilon
converts underscores "_" to hyphens "-" and converts
identifiers to lower case. For example, when invoking a command that
has been defined in an EEL source file as this_command(), you type
this-command. All characters are significant, and no
identifier (or any token, for that matter) may be longer than 1999
characters.The following identifiers are keywords, and you cannot use them for any other purpose:
if switch struct static
else case union unsigned
for default keytable enum
do goto typedef color_class
while sizeof buffer save_spot
return char window save_var
break short command spot
continue int on on_exit
user volatile zeroed color_scheme
byte int32
The keywords enum, unsigned, and static have no function
in the current version of EEL, but we reserve them for future use.
