How Can I Recover Access to the Removed `exp/html` Package in Go1?

Recovering exp/html in Go1: An In-Depth Guide

Go1 introduced significant changes, including the removal of the exp/ codebase. This has left developers who rely on libraries such as exp/html in a quandary. However, there are several viable methods to restore access to these functionalities.

One suggested approach involves creating a symbolic link from the installed Go source code in $HOME/go/src/pkg/exp to the GOPATH. This method can be implemented by following these steps:

• Clone the go repository to $HOME/repo:

cd $HOME/repo
hg clone https://go.googlecode.com/hg/go

• Create a symbolic link in the GOPATH:

cd $HOME/go/src
ln -s $HOME/repo/go/src/pkg/exp .

However, it's important to note that the exp/html library has been removed for a reason. It was incomplete and lacked the necessary functionality to justify its inclusion in the standard Go library.

If you still desire to utilize exp/html, you can attempt to retrieve it using the command:

go get code.google.com/p/go/src/pkg/exp/html

Alternatively, you may prefer a more comprehensive HTML parser such as go-html-transform, which provides HTML5 parsing and CSS selector-based scraping capabilities.

go get code.google.com/p/go-html-transform/

If neither of these solutions satisfy your needs, the final option is to install the Go source code and build it locally, ensuring access to exp/html. This process is relatively straightforward and can be accomplished by following these steps:

• Clone the Go source code:

  hg clone https://go.googlecode.com/hg go

• Install the Go source code:

  cd go/src
  ./all.bash

These methods will restore access to exp/html, allowing you to continue utilizing its functionalities in your Go code. However, it's crucial to keep in mind that exp/html is no longer part of the standard Go library, and its long-term support cannot be guaranteed.
