kandi X-RAY | afero Summary
Afero is a filesystem framework providing a simple, uniform and universal API interacting with any filesystem, as an abstraction layer providing interfaces, types and methods. Afero has an exceptionally clean interface and simple design without needless constructors or initialization methods. Afero is also a library providing a base set of interoperable backend filesystems that make it easy to work with afero while retaining all the power and benefit of the os and ioutil packages. Afero provides significant improvements over using the os package alone, most notably the ability to create mock and testing filesystems without relying on the disk. It is suitable for use in any situation where you would consider using the OS package as it provides an additional abstraction that makes it easy to use a memory backed file system during testing. It also adds support for the http filesystem for full interoperability.

QUESTION
I have a embed.FS
, like:
ANSWER
Answered 2022-Apr-02 at 13:32embed.FS
is a specific implementation for reading files embedded in the binary - it can't be used for filesystems built at runtime.
There are some fs.FS
implementations in the standard library that may work for your use case. You could process your files into:
- A temporary filesystem directory and pass to
os.DirFS
. - An in-memory ZIP file and use
archive/zip.Reader
as anfs.FS
. testing/fstest.MapFS
. This is really intended for testing, but it is there..
Personally, I'd would either:
- Minify via
go generate
before building the binary and usingembed.FS
. This could provide a smaller binary with less startup time/memory usage. - Write my own
fs.FS
or pull in a dependency if the files need to be modified at runtime. It's not much code.
QUESTION
I understand that it is the expected behavior of go mod tidy
to prune dependencies tree by removing the unnecessary ones, but part of my CI uses go-swagger
to generate swagger JSON
files. So, in the end. go mod tidy
will remove the go-swagger
packages from go.mod
file because they're listed as //indirect
(they're not used directly from the source code). Is there a workaround?
Here's my go.mod
file:
ANSWER
Answered 2021-Feb-21 at 21:04I suspect one workaround would be to:
- import explicitly in one of your project source .go file the package
github.com/go-swagger/go-swagger/scan
- define a dummy variable
QUESTION
When I try to run code snippet on playground (snippet) , I get an error:
...ANSWER
Answered 2020-Oct-29 at 09:25playground - timeout running go build [...] Could I solve it❓
No. Sorry.
The Playground is a playground and not a build server or an application server.
QUESTION
I have to following code:
package analyzer
...ANSWER
Answered 2020-Jun-15 at 15:13So the problem lied with wrong imports.
Basically Deployments
are defined in apps/v1beta2
. What I was doing was importing "k8s.io/api/apps/v1beta1"
. I needed to change it to "k8s.io/api/apps/v1beta2"
Also for fetching that I needed to refer to clientset.AppsV1beta2()
instead of clientset.ExtensionsV1beta1()
