Mercurial中的软链接 [英] Soft link in Mercurial

问题描述

在Mercurial中是否有与目录或文件的NIX软链接或硬链接等效的内容.

Is there some equivalent in Mercurial to NIX soft- or hard- links to directories or files.

基本上，文件(或目录)链接到文件其他位置"并遵循该位置的版本(与我认为的常规分支不同，我认为常规分支必须合并)

Basically that a file (or directory) is linked to a file "somewhere else" and follows the version of that location (Unlike a regular branch I think, where one would have to merge)

推荐答案

存储库内部的Mercurial版本软链接非常好.它会检测它们，记录它们，并为您创建它们.您是否在寻找特定的用例?子库是最接近存储库外部的链接的子存储库，它是指向另一个存储库的特定版本的指针.

Mercurial versions soft links that are internal to the repository just great. It'll detect them, record them, and create them for you. Is there a specific use case you're looking for? The closest thing to an link that reaches outside the repository is a subrepo, which is a pointer to a specific version of another repo.

符号链接有效
