Add capacity to specify separator for util.format(), instead of space ' '. #27114
Description
Is your feature request related to a problem? Please describe.
Many logger use util.format as the underlying implementation. e.g winston.logger.
So
logger.warn(1, 2, 3);
got result: 1 2 3
This is ok when log is simple, but for real world, space separated log is not easy to analysis.
I have to write like
logger.warn(v0 + '|' + v1 + '|' + v2);
or
logger.warn(``${v0}|${v1}|${v2}``); (how can i put single ` in github's code...)
Describe the solution you'd like
Consider add an env variable like process.env.NODE_FORMAT_SEPARATOR
code node/lib/internal/util/inspect.js line: 1541
while (a < args.length) {
const value = args[a];
str += join;
str += typeof value !== 'string' ? inspect(value, inspectOptions) : value;
join = ' ';
a++;
}
can be
const sepor = process.env.NODE_FORMAT_SEPARATOR || ' ';
while (a < args.length) {
const value = args[a];
str += join;
str += typeof value !== 'string' ? inspect(value, inspectOptions) : value;
join = sepor;
a++;
}
Describe alternatives you've considered
or just add a function to util to specify separator.
