如何可视化Fortran（90或更高版本）的源代码，例如使用Graphviz？ [英] How can I visualize Fortran (90 or later) source code, e.g. using Graphviz?

问题描述

我需要为这个项目做出贡献，我认为我应该谨慎行事首先了解源代码。

作为第一步，我想要显示各种源文件之间的相互依赖关系，即哪些源文件需要哪些模块。据我所知，自动化方法存在于其他语言，并产生一个图形，可以使用Graphviz构建。

但是有谁知道那里的软件可以为Fortran 90代码做这件事？

解决方案

如果你有钱，那么了解Fortran 值得一看。如果你没有钱，但打算快速工作，那么你可以通过试用软件下载。

对于静态调用图，我从来没有发现一个免费的工具和Understanding一样有用;很难找到任何免费工具，更不用说有用的工具了。我会自己写一个，但市场会很小： - （

）

对于动态调用图调查编译器选项，我使用英特尔Fortran编译器，它可以生成有关正在执行的程序的有用信息。TotalView调试器还可以显示正在执行的程序的调用图。您还应该查看 gprof2dot 这使得一个DOT文件脱离了GPROF调用'graph'。这是免费的，OK。

我应该还补充说，虽然这不是我曾经使用过的，但可以使用 Callgrind 。

I've been thrown into a large Fortran project with a large number of source files.

I need to contribute to this project and it would seem prudent that I first understand the source.

As a first step, I'd like to visualize the interdependences between the various source files, i.e. which source files need which modules. As far as I can tell, automated methods exist for other languages and result in a graph that can be built using Graphviz.

But is anyone aware of software out there that can do this for Fortran 90 code?

解决方案

If you have money then Understand for Fortran is worth looking at. If you don't have money but intend to work quickly then you might get by with a trial download of the software.

For a static call graph, I've never found a free tool as useful as Understand; it's hard to find any free tools let alone a useful one. I'd write one myself but the market would be tiny :-(

For a dynamic call graph investigate your compiler options. I use the Intel Fortran Compiler which can generate a mound of useful information about an executing program. The TotalView debugger can also visualise the call graph of an executing program. You should also look at gprof2dot which makes a DOT file out of a GPROF call 'graph'. This is free and OK.

And I should also add, though it's not something I've ever used, that Callgrind may be of use.
