Переменные окружения (Environment variables)
The following environment variables shall affect the execution of
yacc:
LANG Provide a default value for the internationalization
variables that are unset or null. (See the Base
Definitions volume of POSIX.1‐2017, Section 8.2,
Internationalization Variables for the precedence of
internationalization variables used to determine the
values of locale categories.)
LC_ALL If set to a non-empty string value, override the values
of all the other internationalization variables.
LC_CTYPE Determine the locale for the interpretation of
sequences of bytes of text data as characters (for
example, single-byte as opposed to multi-byte
characters in arguments and input files).
LC_MESSAGES
Determine the locale that should be used to affect the
format and contents of diagnostic messages written to
standard error.
NLSPATH Determine the location of message catalogs for the
processing of LC_MESSAGES.
The LANG and LC_* variables affect the execution of the yacc
utility as stated. The main() function defined in Yacc Library
shall call:
setlocale(LC_ALL, "")
and thus the program generated by yacc shall also be affected by
the contents of these variables at runtime.
