After work bike tour
I admit it, I should rename the subtitle of my blog from “Thoughts of an IT expert” to “My bike tour log”.

Question to all you Gophers out there: How do you deal with custom errors that include more information and different kinds of matching them?

I started with a simple var ErrPermissionNotAllowed = errors.New("permission not allowed"). In my function I then wrap that using fmt.Errorf("%w: %v", ErrPermissionNotAllowed, failedPermissions). I can match this error using errors.Is(err, ErrPermissionNotAllowed). So far so good.

Now for display purposes I’d also like to access the individual permissions that could not be assigned. Parsing the error message is obviously not an option. So I thought, I create a custom error type, e.g. type PermissionNotAllowedError []Permission and give it some func (e PermissionNotAllowedError) Error() string { return fmt.Sprintf("permission not allowed: %v", e) }. My function would then return this error instead: PermissionNotAllowedError{failedPermissions}

At some layers I don’t care about the exact permissions that failed, but at others I do, at least when accessing them. A custom func (e PermissionNotAllowedError) Is(target err) bool could match both the general ErrPermissionNotAllowed as well as the PermissionNotAllowedError. Same with As(…). For testing purposes the PermissionNotAllowedError would then also try to match the included permissions, so assertions in tests would work nicely. But having two different errors for different matching seems not very elegant at all.

Did you ever encounter this scenario before? How did you address this? Is my thinking flawed?

I played around with parsers. This time I experimented with parser combinators for twt message text tokenization. Basically, extract mentions, subjects, URLs, media and regular text. It’s kinda nice, although my solution is not completely elegant, I have to say. Especially my communication protocol between different steps for intermediate results is really ugly. Not sure about performance, I reckon a hand-written state machine parser would be quite a bit faster. I need to write a second parser and then benchmark them.

lexer.go and newparser.go resemble the parser combinators: https://git.isobeef.org/lyse/tt2/-/commit/4d481acad0213771fe5804917576388f51c340c0 It’s far from finished yet.

The first attempt in parser.go doesn’t work as my backtracking is not accounted for, I noticed only later, that I have to do that. With twt message texts there is no real error in parsing. Just regular text as a “fallback”. So it works a bit differently than parsing a real language. No error reporting required, except maybe for debugging. My goal was to port my Python code as closely as possible. But then the runes in the string gave me a bit of a headache, so I thought I just build myself a nice reader abstraction. When I noticed the missing backtracking, I then decided to give parser combinators a try instead of improving on my look ahead reader. It only later occurred to me, that I could have just used a rune slice instead of a string. With that, porting the Python code should have been straightforward.

Yeah, all this doesn’t probably make sense, unless you look at the code. And even then, you have to learn the ropes a bit. Sorry for the noise. :-)
