doxygen 正在生成空文档

Question

我在 C++（和一些 CUDA）中有一个 source repository，我想对它进行 doxygenate。我已将 doxygen cmets 添加到一些（但不是全部）代码中；生成了一个 Doxygen 配置文件，并使用它运行 doxygen 以查看部分输出。

我得到的是：什么都没有。空的。

生成了一个主页，但它没有显示任何内容 - 即使我专门设置了EXTRACT_ALL = YES（在使用EXTRACT_ALL = NO 得到空结果之后。

为什么什么都没有生成，我该如何解决？

注意事项：

• 所有头文件都有@file cmets。
• 我已将与 CUDA 相关的扩展添加到允许的模式中
• 我有这个问题的早期版本，没有答案，之后情况发生了一些变化（所以我删除了那个）。
• 即使从doxygen.cfg 中删除大部分行（见下文），问题仍然存在。

doxygen.cfg（更短的版本，过滤掉了 cmets）：

Answer 1

TL;DR：删除 FILE_PATTERNS 变量中的逗号并使其以空格分隔。

代替：

FILE_PATTERNS          = *.c, *.cc, *.cxx, *.etc

你应该使用：

FILE_PATTERNS          = *.c *.cc *.cxx *.etc

说明

@albert 是破解这个难题的人...

Doxygen 生成的配置文件说：

# If the value of the INPUT tag contains directories, you can use the
# FILE_PATTERNS tag to specify one or more wildcard patterns (like *.cpp and
# *.h) to filter out the source-files in the directories.
#
# Note that for custom extensions or not directly supported extensions you also
# need to set EXTENSION_MAPPING for the extension otherwise the files are not
# read by doxygen.
#
# If left blank the following patterns are tested:*.c, *.cc, *.cxx, *.cpp,
# *.c++, *.java, *.ii, *.ixx, *.ipp, *.i++, *.inl, *.idl, *.ddl, *.odl, *.h,
# *.hh, *.hxx, *.hpp, *.h++, *.cs, *.d, *.php, *.php4, *.php5, *.phtml, *.inc,
# *.m, *.markdown, *.md, *.mm, *.dox, *.py, *.pyw, *.f90, *.f, *.for, *.tcl,
# *.vhd, *.vhdl, *.ucf, *.qsf, *.as and *.js.

FILE_PATTERNS          = 

此注释具有误导性，因为它为您提供了一个以逗号分隔的列表，而实际上逗号不被视为分隔符。如果您使用该列表（并且可能添加/更改它），就像在 OP 的示例中一样，Doxygen 会看到一个模式列表，其扩展名具有尾随 , 字符。而且 - 它不会抱怨。它也不会抱怨忽略存储库中的所有文件 - 它只是以空结果结束。

删除, 字符会生成非空文档。

注意：从 Doxygen 版本 1.8.15 开始，这应该不再是问题，并且应该接受逗号作为字段的分隔符。
