常见的Lisp-获取文件的路径 [英] common lisp - get path to file

问题描述

在Common Lisp中，是否有办法获取已编译文件的路径(类似于当前目录)?

In Common Lisp, is there a way to get the path to a compiled file (something like current-directory)?

该文件不在当前目录文件夹中.

The file is not inside the current-directory folder.

推荐答案

这应该是一个注释，但是我将给出一些代码示例，这些示例可能会有助于原始海报.

This ought to be a comment but I'm going to give some code examples that might help the original poster along.

首先，您需要更加清楚自己想做什么.您要解决的问题是什么?

First of all, you need to be a little more clear about what you want to do. What is the problem you're trying to solve?

第二，下面是一些有用的示例:

Secondly, here are a couple of examples which could be useful:

• *default-pathname-defaults* 通常设置为启动CL映像的目录在:

• *default-pathname-defaults* usually set to the directory the CL image was started up in:

* *default-pathname-defaults*
#P"/Users/aerique/"

merge-pathnames 允许您构造新的路径名:

merge-pathnames allows you to construct new pathnames:

* (merge-pathnames "lib/misc" *default-pathname-defaults*)
#P"/Users/aerique/lib/misc"
* (merge-pathnames "lib/misc/" *default-pathname-defaults*)
#P"/Users/aerique/lib/misc/"

asdf:system-source-directory返回加载了 ASDF 的系统的路径:

asdf:system-source-directory returns the path to a system loaded with ASDF:

* (asdf:system-source-directory :linedit)  
#P"/Users/aerique/quicklisp/dists/quicklisp/software/linedit-20111203-git/"
