gopkg | example for the go pkg 's function

go.mod and vendor/modules.txt (if present) must be in sync.

Whenever go.mod changes and there is a vendor directory, go mod vendor needs to be run to update the contents of the vendor directory.

All direct dependencies (not marked // implicit in go.mod) are "explicit" and marked accordingly in vendor/modules.txt starting from Go 1.14.

After running go mod vendor notice the new line ## explicit added after the package reference:

As mkopriva, said in the comments, you should change to []string, so the struct would be

A couple of options, use a https://github.com/getkin/kin-openapi to parse your YAML. The example below will require you to convert your YAML to JSON.

It seems the fields on your Server struct need to be public in order for the yaml module to read them.

From the Marshal documentation:

Struct fields are only marshalled if they are exported (have an upper case first letter)

You can fix this by changing the type definition for Server so that the fields are exported (have capitalized names), like so:

You're almost there.

To "promote" yaml struct tag(s) to the "parent" field, add:

Let's clear the concept of "contact forms".

Web sites usually provide a "Contact us" functionality. The website presents a contact form which the user fills. The user usually provides his/her email address, and the message (and preferably the subjuct / topic).

On submit, the backend saves this message in the webapps own database.

When an admin (or an appropriate person) reads the message (in a restricted page), the admin may decide to reply to this message. Since the user provided his/her email address when submitting the contact form, the reply may happen via email. The admin may fill a form which includes the reply message (preferably quoting the original message too), and when the admin submits this form, the backend can send an email to the address provided by the user (when submitting the contact form).

This email will contain the message entered by the admin as the body. The subject should contain the subject from the contact form as the Subject header. This email will be sent to the address provided by the user. The email will be sent from the address of the admin (or any email address set in the backend, but certainly not from the email provided by the user).

Example of sending a reply email by the admin (from the backend):

Open VSC from $WORKSPACE/go. Follow the instruction of https://github.com/golang/tools/blob/master/gopls/doc/advanced.md#working-on-the-go-source-distribution as @hana mentioned:

1. Compile the Go binary. Change working directory to $WORKSPACE/go/src and run ./make.bash (or ./make.bat for Windows cmd). It will generate the $WORKSPACE/go/bin directory.

2. Set "go.goroot" to "${workspaceFolder}" and install all Go tools required.

That error is a package level var - essentially, a singleton - so comparison is appropriate:

The conda run function provides a clean way to run code within an environment context without having to manually activate. Try something like
