How to safe delete the usages of struct field on all files from Intellij?
问题
尽管我们有重构工具可以重命名结构字段，但我们没有用于删除结构字段及其使用的重构工具。
如何安全地从任何支持golang的IDE中删除结构字段及其使用（包括读写访问）？
据我所见，目前没有任何IDE（如vim-go、intellij）支持此功能。
我曾考虑过删除结构字段并运行go vet命令，在每个文件上返回所有错误（包括行号），然后编写一个脚本来删除这些行，但不幸的是，vet在遇到第一个错误后就停止报告错误了。
英文:
Though we have refactoring tool to rename the struct field we do not have refactoring tool for deleting the struct field & its usages.
How to safely delete the struct field and its usages[Write & read access] across the files from any IDE that supports golang?
As far as I have seen none of the IDE(vim-go, intellij) supports this.
I had thought of deleting the struct field & run
go vet
which will return all error(along with line number) on every file & write a script to delete those lines but unfortunately vet stops reporting errors after very first error encountered in a file.

这不是可以完全自动化的事情。假设你从类型Point struct {X, Y int}中删除字段X，当它被如下方式使用时，IDE应该怎么做呢：
p := Point{X: 1, Y: 2}
r := p.X / p.Y
或者像这样：
func f(x, y int) {}
f(p.X, p.Y)
很明显，所需的操作不是IDE可以“猜测”的。
要删除一个结构体字段，你需要从类型定义中删除它，并手动修复编译器错误。
英文:
This is not something that could be fully automated. Let's say you remove the field X from the type Point struct {X, Y int}. What should the IDE do when it's used like this:
p := Point{X: 1, Y: 2}
r := p.X / p.Y
Or like this:
func f(x, y int) {}
f(p.X, p.Y)
What's needed is obviously not something the IDE could "guess".
To delete a struct field, delete it from the type definition and proceed to fix the compiler errors manually.
