There's probably value to inlining a simple equation like that. You could make it an inline function though, and get the benefits of inlining while still encapsulating it. Sort of like a macro, but with the same side-effects as a normal function call.
Probably a simple one.
Basically I am retrieving a number from a file - setting a variable against it and then incrementing this by 1 and using this as an entry number in a log file for messages. I need the variable to re-evalute itself each time I call it so I get the latest number in the file -... (1 Reply)

MANCONV(1) Manual pager utils MANCONV(1)NAME
manconv - convert manual page from one encoding to another
SYNOPSIS
manconv -f from-code[:from-code...] -t to-code [-dqhV] [filename]
DESCRIPTION
manconv converts a manual page from one encoding to another, like iconv. Unlike iconv, it can try multiple possible input encodings in
sequence. This is useful for manual pages installed in directories without an explicit encoding declaration, since they may be in UTF-8 or
in a legacy character set.
If an encoding declaration is found on the first line of the manual page, that declaration overrides any input encodings specified on man-
conv's command line. Encoding declarations have the following form:
'" -*- coding: UTF-8 -*-
or (if manual page preprocessors are also to be declared):
'" t -*- coding: ISO-8859-1 -*-
OPTIONS -f encodings, --from-code encodings
Try each of encodings (a colon-separated list) in sequence as the input encoding.
-t encoding, --to-code encoding
Convert the manual page to encoding.
-q, --quiet
Do not issue error messages when the page cannot be converted.
-d, --debug
Print debugging information.
-h, --help
Print a help message and exit.
-V, --version
Display version information.
