列出Gnat中未使用的文件 [英] List unused files in Gnat

问题描述

我在GNAT中有一个项目，我想列出所有从未使用过的文件。我正在考虑使用python脚本执行此操作，但是，使用GNAT可以轻松做到这一点吗？

I have a project in GNAT and I would like to list all the files that are never used. I am thinking about doing it with a python script, but, is it possible to do so easily with GNAT?

我发现了有关gnatelim的信息，但尽管在帮助中它说有-P选项

I found about gnatelim, but although in the help it says to have the -P option

usage: gnatelim [options] -main=main_unit_name {filename} [-cargs gcc_switches]

options:
 --version - Display version and exit
 --help    - Display usage and exit

 -Pproject     - Use project file project. Only one such switch can be used.

似乎不起作用，因为它要求一个主要单元（拥有整个项目！） ：

It seems that it does not work as it asks for a main unit (having the whole project!):

>gnatelim -Prelease.gpr
gnatelim: No main unit specified
try "gnatelim.exe --help" for more information.

我正在使用GNAT 2015

I am using GNAT 2015

推荐答案

gnatelim 的帮助非常有限，但是我做了一些实验，而窍门似乎是通过了 gnatelim 主机的文件名：

The help for gnatelim is rather limited, but I have experimented a bit, and the trick seems to be to pass gnatelim the file name of your main unit:

gnatelim main.adb

如果您的项目比包含所有所需源文件的单个目录更复杂，则可以传递 gnatelim 既是项目文件，也是您主体的文件名：

If your project is more complicated than a single directory containing all needed source files, you pass gnatelim both a project file and the file name of your main unit:

gnatelim -P black_examples.gpr client.adb
