使用VSCode对Golang程序进行调试时会遇到数据截断问题，string只显示前64个字符，array只显示前64个数据。经查dlv是支持以参数方式来控制的。

发现VSCode的Golang插件里面有个叫做go.delveConfig的配置，是可以设置dlv参数的。分享一下我的整个Golang配置：

    "go.buildOnSave": "off",
    "go.formatTool": "goimports",
    "go.lintTool": "golangci-lint", //go get -u github.com/golangci/golangci-lint/cmd/golangci-lint
    "go.autocompleteUnimportedPackages": true,
    "go.gotoSymbol.includeImports": true,
    "go.useLanguageServer": true,
    "go.delveConfig": {
        "dlvLoadConfig": {
            "followPointers": true,
            "maxVariableRecurse": 3,
            "maxStringLen": 1024,
            "maxArrayValues": 1024,
            "maxStructFields": -1
        },
    },
    "[go]": {
        "editor.formatOnSave": true,
        "editor.codeActionsOnSave": {
            "source.organizeImports": true
        }
    },

需要改的主要是maxStringLen、maxArrayValues、maxVariableRecurse这三个字段。
