Idiomatic way of naming Getters in Go

The Effective go has following advice on naming of getters:

Go doesn't provide automatic support for getters and setters. There's nothing wrong with providing getters and setters yourself, and it's often appropriate to do so, but it's neither idiomatic nor necessary to put Get into the getter's name. If you have a field called owner (lower case, unexported), the getter method should be called Owner (upper case, exported), not GetOwner. The use of upper-case names for export provides the hook to discriminate the field from the method. A setter function, if needed, will likely be called SetOwner. Both names read well in practice:

Now, this advice doesn't seem to consistent as the stdlib itself violates this multiple times.

As you can see in above screenshot, there are multiple methods which use GetX naming convention which is advised against in the effective go guide.

So the question is is the advice given in guide wrong or these methods are named wrongly & would be fixed in future versions?

[go-nuts] FunctionName caseinconsistencies

A lot of the all lowercase names were chosen before we had really figured out what the naming conventions should be. The rule we adopted, which might be worth revisiting later, was that entry points in package os or syscall, which are named after equivalents in C, just had a single capital at the beginning, to avoid needing to decide where the internal capitalizations are in abbreviations like geteuid or getwd or chdir. Names like Readdirnames, which are actual words, might be worth revisiting at some point.

os: inconsistent casing in names #1187

Is there any sort of rule about the casing of functions used in the "os" package? Looking through, it doesn't sound like it's very easy to recall whether a given function should be called LikeThat or Likethat.

For instance:
Mkdir
MkdirAll
TempDir
Getenv
ForkExec
Readlink
ReadAt
Readdir
It feels very ad-hoc, and hard to recall.

It's a known issue. It's unplanned.
