allow wildcard match in util.debuglog() #17605
Description
- Version: all
- Platform: all
- Subsystem: util
Refs: #13728
Currently, util.debuglog() doesn't support wildcard. It will be more dev friendly if it could.
Consider the structure below,
├── classifiers
| ├── logical-regression.js
| └── linear-regression.js
| └── decision-tree.js
| └── ..lots of files...
├-index.js
we might have different files in the same module, and we really don't want to output those logs at the same time.
So a possible solution could be, we define a prefix/postfix to the same module, e.g. util.debuglog('classifiers-logical-regressions'), util.debuglog('classifiers-linear-regression')
Then we could define the NODE_DEBUG below to output *-regressions only logs, would be logical-regression and linear-regression in this case.
> SET NODE_DEBUG=classifiers-*-regression
> node index.js
Please feel free to add more comments.

Thanks for opening this issue! This is something I always wanted to have :)
I opened #17607 to propose an implementation.

@targos Oh thx, I just finish my implementation also. Should I propose mine or make some changes on your codebase?

Oh sure, go ahead and open a PR with yours 😉
