EXTERNAL INFLUENCES
Support for international codes and environment variables are as follows:
Environment Variables
UNIX95 specifies using the XPG4 behaviour for this command.
COLUMNS overrides the system-selected horizontal screen size.
LINES overrides the system-selected vertical screen size, used as the number of lines in a screenful and
the vertical screen size in visualmode.
SHELL is a variable that shall be interpreted as the preferred command-line interpreter for use in
!,
shell, read, and other commands with an operand of the form
!string. For the shell command
the program shall be invoked with the two arguments
-c and string. If this variable is null or not set,
the
sh utility shall be used.
TERM is a variable that shall be interpreted as the name of the terminal type. If this variable is unset or
null, an unspecified default terminal type shall be used.
PATH determines the search path for the shell command specified in the editor commands, shell
, read,
and
write. EXINIT determines a list of ex commands that will be executed on editor startup, before
reading the rst file. The list can contain multiple commands by separating them using a vertical line (|)
character.
HOME determines a pathname of a directory that will be searched for an editor startup file named
.exrc.
LC_ALL This variable shall determine the locale to be used to override any values for locale categories
specified by the setting of LANG or any environment variables beginning with LC_.
LC_MESSAGES determines the locale that should be used to affect the format and contents of diagnostic
messages written to standard error and informative messages written to standard output.
LC_COLLATE determines the collating sequence used in evaluating regular expressions and in processing
the tags file. LC_CTYPE determines the interpretation of text as single and/or multi-byte characters, the
classification of characters as uppercase or lowercase letters, the shifting of letters between uppercase and
lowercase, and the characters matched by character class expressions in regular expressions.
LANG determines the language in which messages are displayed.
LANGOPTS specifies options determining how text for right-to-left languages is stored in input and output
files. See environ(5).
If LC_COLLATE or LC_CTYPE is not specified in the environment or is set to the empty string, the value
of LANG is used as a default for each unspecified or empty variable. If LANG is not specified or is set to the
empty string, a default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable
contains an invalid setting, the editor behaves as if all internationalization variables are set to "C". See
environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
WARNINGS
See also the WARNINGS section in ex(1).
Program Limits
vi places the following limits on files being edited.
Maximum Line Length
LINE_MAX characters (defined in <limits.h>), including 2-3 bytes for overhead. Thus, if the value
specified for LINE_MAX is 2048, a line length up to 2044 characters should cause no problem.
