Mercurial:无需克隆即可获取有关存储库的信息 [英] Mercurial: get information about repositories without cloning them

问题描述

几天前，我开始尝试使用Mercurial，直到一切顺利，直到我决定尝试编写一个小程序，该程序可以从远程服务器获取存储库列表和每个存储库的变更集ID列表，从而使用户能够选择存储库和变更集，将其克隆并更新到所选修订版.这导致了两个问题:

Few days ago I started experimenting with Mercurial, and everything went great, until I decided to try writting a small program, that gets the list of repositories and lists of changeset IDs for each repository from a remote server, allows the user to pick repository and changeset, clones it and updates to the chosen revision. This led to two questions:

1. 是否有一种方法可以从服务器获取存储库列表(除了解析HTML外)?
2. 有没有一种方法可以获取有关其中一个存储库的信息，例如标签，分支等，而无需先将其克隆?

推荐答案

否，Mercurial的设计目的是使您几乎所有命令都需要一个 local 存储库.唯一可以为您提供有关远程存储库信息的内置命令是hg id:

No, Mercurial is designed so that you need a local repository for almost all commands. The only built-in command that will give you information about a remote repository is hg id:

$ hg id https://bitbucket.org/aragost/javahg/
3b2711b26dbd

要获取更多信息，有时可以利用raw模板作为hgweb:

To get hold of more information you can sometimes exploit the raw template for hgweb:

$ wget -q -O - 'https://www.mercurial-scm.org/repo/hg/tags?style=raw' | head

这要求主机正在运行Mercurial随附的hgweb CGI脚本.对于类似Bitbucket的网站，您需要使用其API .

That requires that the host is running the hgweb CGI script that comes with Mercurial. For a site like Bitbucket you would need to use their API.

最后，如果您可以在远程存储库上启用扩展，则可以编写一个扩展，以可解析的格式公开所需的信息.我曾经写过这样的扩展名作为演示.

Finally, if you can enable extensions on the remote repository, then it's possible to write an extension that exposes the information you want in a parsable format. I once wrote such an extension as a demo.
