QUESTION
I am looking for unmarshaling simple yaml but something is not right. Have spent enough time already. Any help please?
...ANSWER
Answered 2021-Jun-04 at 22:08You have to export the fields in your struct. As stated in the api-documentation:
Struct fields are only unmarshalled if they are exported (have an upper case first letter), and are unmarshalled using the field name lowercased as the default key.

I see a problem in your code the link you have shared is https://github.com/go-playground/validator
but in the code, import is gopkg.in/validator.v2
If you are using the go-playground validator
Use below code to validate
QUESTION
I have a problem unmarshaling a simple slice of YAML data:
...ANSWER
Answered 2021-May-14 at 10:29If you don't specify the mapping between labels used in the YAML source and Go struct fields, by default they will only be matched if only changing the first letter to lower matches.
E.g. the struct field Name
will match name
, but not NAME
.
Specify the mapping for the HTTP
field:

ANSWER
Answered 2021-Mar-12 at 04:23According to the documentation you should make the struct fields public in order for unmarshal to correctly populate the data.:
Struct fields are only unmarshalled if they are exported (have an upper case first letter)
Your code works as expected after changing the type definitions as follows:

How to read YAML properties with leading zeros as string without any conversion?
YAML example file:
...ANSWER
Answered 2021-Mar-10 at 11:15Now that we found the error, let's have a post mortem about what happened:
The library you used, github.com/ghodss/yaml, says that
this library first converts YAML to JSON using go-yaml and then uses json.Marshal and json.Unmarshal to convert to or from the struct.
It doesn't particularly help that the linked blog post about why this would be a good idea vanished. Anyway, let's see what the code there actually does:
QUESTION
Because the default azure-pipelines.yml template for building go code does not support go modules it is not obvious how it would look like to support it.
This is the default template which is not working for go.modules:
...ANSWER
Answered 2021-Feb-26 at 09:50I like to share also the answer here for a template that builds a go modules package correctly. Maybe this is just for your inspiration what needs to be considered. It took me some time to get there.
The main pain point is that the the default template sets the GOPATH to the pipeline workingdirectory which is just wrong if you will download modules via go mod download
into it. This would lead to inaccesible files in the next pipeline run, making the pipeline failing during repository checkout.
The following approach just sets GOPATH to the Agent.HomeDirectory which also makes downloaded modules available for subsequent pipeline runs.
Maybe it helps someone
QUESTION
I'm used to search and install packages with apt, under Debian-based distributions, and one useful feature of it is that you can search in the description of packages as well, so you don't need to know the exact name of a package to find it. It can be used in a exploratory way. For example, say I'm searching for packages related to functional programming, but haven't a specific one in mind. I could do just this:
...ANSWER
Answered 2021-Jan-15 at 23:53No, it is not possible to search package descriptions with conda search
. The query results of conda search
, including those with the --info|-i
flag, do not include package description info.
There is limited functionality for retrieving package summaries from Anaconda Cloud. This is provided by the anaconda show
command in the package anaconda-client
and only provides exact matching (channel and package). For example,
QUESTION
This is a my Go project.
...ANSWER
Answered 2021-Jan-03 at 04:59The issue is that different tools you use produce binary in (or run binary from) different place. Path to config.ini
in your code is specified as relative to process' current working directory. If you want non-invasive solution you'd need to change your workflow (where you build and run the main binary, debugger or go test) or you can implement some fallback mechanism or environment variable that will override default path to config file.
In VSCode there should be cwd
variable in launch.json
configuration that allows you to set working directory. You should be able to set cwd: "${workspaceFolder}"
and that should work as if you run commands from the root of repository.
See https://code.visualstudio.com/docs/editor/variables-reference for variables reference.
QUESTION
Inside docker, it seems that I cannot compile my gRPC micro-service due to this error:
...ANSWER
Answered 2020-Sep-07 at 00:39The gist of this error is that the version of binary used to generate the code isn't compatible with the current version of code. A quick and easy solution would be to try updating the protoc-gen-go
compiler and the gRPC library to the latest version.
go get -u github.com/golang/protobuf/protoc-gen-go
