给定缩小文件后，如何查找D3的确切版本? [英] How to find the exact version of D3 given the minified file?

问题描述

我在使用大量D3的旧系统上工作.不幸的是，几年前将我们缩小版的d3.js提交回购交易的人没有记录该文件的哪个版本，所以现在我试图确切地找到该文件的哪个版本，以便可以与webpack一起很好地玩.评估升级D3会发生什么情况.

I work with a legacy system that uses a lot of D3. Unfortunately, the person who committed our minified d3.js to the repo years ago didn't document which version it was, so now I'm trying to find exactly which version it is so I can get it to play nice with webpack and also assess what would need to happen to be able to upgrade D3.

鉴于此信息，找到我们拥有的D3版本的最佳方法是什么?

What is the best way to find the version of D3 we have, given this info?

提交时间为2013-09-05，文件本身具有shasum 8c20d53ba2c073a0b939b06847f12204ba0f81c6.我在此处发布中检查了3.3.[0-3].对我的文件进行比较，但没有找到它.

The commit was on 2013-09-05 and the file itself has shasum 8c20d53ba2c073a0b939b06847f12204ba0f81c6. I checked 3.3.[0-3] in the releases here by doing a diff with my file, but didn't find it.

我也制作了一个bash脚本来找到它，但是找不到它:

I also made a little bash script to find it, but couldn't locate it:

#!/usr/bin/env bash

for tag in $(  git tag -l | grep -e "v2.8.*" -e "v2.9.*" -e "v3.0.*" ); do
    echo -e "\n"
    git checkout $tag > /dev/null;
    for jsfile in *.js; do
      sha=$(shasum $jsfile | awk "{print $1}")
      if [[ "$sha" == "8c20d53ba2c073a0b939b06847f12204ba0f81c6" ]]; then
        echo "Found it! $tag has file $jsfile with the right sha!"
      fi
    done
done

推荐答案

对于任何D3版本，d3.version都会为您提供已加载的版本，无论版本是否已缩小.

For any D3 release, d3.version gives you the version loaded, wether it is minified or not.

例如，使用D3 v3.3.0:

For instance, using D3 v3.3.0:

console.log(d3.version)

<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.3.0/d3.min.js"></script>

即使在非常老的发行版(例如D3 v1.2)中也可以使用:

That works even for very old releases, like D3 v1.2:

console.log(d3.version)

<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/1.29.5/d3.min.js"></script>

这篇关于给定缩小文件后，如何查找D3的确切版本?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
