'go'工具安装可执行文件后如何访问资源文件？ [英] How to access resource files after the 'go' tool installed the executable?

问题描述

假设运行 go install -v importpath 生成一个可执行文件并将其安装到 $ GOPATH / bin / program 。 go 工具无法安装资源文件。当我运行程序时，我希望它能够访问 $ GOPATH / src / importpath 下的一些资源文件， 。

从安装的可执行文件访问这些资源文件的最佳方式是什么？

解决方案

此问题已被要求多个 <一个href =https://groups.google.com/d/topic/golang-nuts/XksK4klJ0Dg/discussion =nofollow>次在go-nuts邮件列表中。 go 工具目前不提供直接分发更多资源的方式。但是，有两种解决方法可用：

• 编写一个简单的脚本（awk应该足以）将任何文件转换为 .go 文件，它只包含一个字符串常量，并将文件直接嵌入到二进制文件中。例如， Camlistore 项目使用此方法（ camlistored / ui / fileembed.go ）。 go-bindata 做类似的事情。




• go-tour和许多其他项目目前正在使用导入 go / build 包的功能，用于搜索 $ GOPATH中列出的所有 src / 文件夹和 $ GOROOT 来查找包源的正确路径。示例： http：//代码.google.com / p / go-tour / source / browse / gotour / local.go？r = 996704f8ef9e63949b3bc4d94b613ec4a7b5d99a＃53

Lets assume that running go install -v importpath builds an executable and installs it into $GOPATH/bin/program. The go tool is unable to install resource files. When I run the program, I would like it to access some resource files that are under $GOPATH/src/importpath.

What is the best way of accessing such resource files from the installed executable?

解决方案

This question has been asked multiple times on the go-nuts mailing list. The go tool doesn't offer a direct way to distribute additional resources at the moment. However, there are two workarounds available:

• write a simple script (awk should be sufficient) to convert any file into a .go file which just contains a single string constant and embed the file directly into the binary. This approach is used by the Camlistore project for example (camlistored/ui/fileembed.go). go-bindata does similar things.

• go-tour and many other projects are currently using the Import function of the go/build package to search through all src/ folders listed in $GOPATH and $GOROOT to find the correct path of the package sources. Example: http://code.google.com/p/go-tour/source/browse/gotour/local.go?r=996704f8ef9e63949b3bc4d94b613ec4a7b5d99a#53
