File Hierarchy Cannot Handle Nested Directories about exhale

[davidvanwyk]

Based on your comments and where they were leading - I managed to resolve the issue by changing the STRIP_FROM_PATH setting in doxygen to match what was being done by exhale (ie. everything up to and including project directory name). This has resolved the issue.

Hmm. Nested directories are (supposed to be) supported. So what this means is that Doxygen did not create a directory node for this. Or at least os.path.dirname(file) did not result in the same name as any of the directories reported by Doxygen.

Is this code public? It could be a Doxygen config problem, a file documentation comment problem, or a bug in exhale. Doxygen does weird things on Windows where sometimes they report Windows paths and sometimes they report Unix paths. I thought I fixed all of those though.

If the project is not public, can you include the xml for both the file and the directory? I need to see what path names it's using

@svenevs

Unfortunately not a public project.

The relevant file structure is as follows:

    Project/
       docs/
          conf.py
          api/
          doxygen/
             build
             .doxyfile
       test/
          utests/
       include/

If I put the documented .h files from doxygen into utests/; I get the warning and subsequent problem.
If I then go an delete the test/ directory from the doxygen xml folder (both in index and the generated dir xml file), it displays in the html with a folder name of utests

I tried putting in a nested include and had the same issue/"fix"

Here's the xml.zip folder from the doxygen generation.

dir_9350652c807819cafbc8c3aca0b83c13.xml

  <compounddef id="dir_9350652c807819cafbc8c3aca0b83c13" kind="dir">
    <compoundname>C:/...workspace/M..._Test/include/includeAswell</compoundname>
    <innerfile refid="_m_a_x..._8h">MAX....h</innerfile>
    <!-- ... -->
    <location file="C:/...workspace/M..._Test/include/includeAswell/"/>

• directory location is include/includeAswell
• <innerfile> listed is MAX....h (refid in that file tells you what xml to look in for file, refid.xml)

_m_a_x..._8h.xml

    <location file="C:/...workspace/M..._Test/include/MAX....h"/>
  </compounddef>
</doxygen>

• file definition says it's in include/, not include/includeAswell

---

That seems to be the conflict. So exhale gets confused about which directory to put it in. Did you put a comment like /** \file MAX....h */ at the top of the file? If so, try changing it to just /** \file */ without the filename in there?

"Could not find directory parent of file [bar.h] with location [Project\include\nestedInclude\bar.h]."

This seems to be the opposite of the reported message though, where this one the file said it was there in include/includeAswell? Which file was bar.h?

If you share the doxygen configuration you are using / the relevant section of conf.py that sets up exhale I'm happy to take a look and see if anything stands out, but I'm hoping it's a /** \file */ mishap 🙂

[davidvanwyk]

Oops - I introduced that error by not doing a clean build :P Sorry! I removed the "includeAswell" directory and shifted the associated .h to the parent so the problem would just exist with the utests directory so it could be isolated.

Rather look at this.

dir_13e138d54eb8818da29c3992edef070a.xml

Is the one throwing the warning. It has an "Innerdir" of:

dir_347f78c5bf8b9dbad860aafd5b962aba.xml

Which has the 2 "innerfile"s that I get the warnings from. In this particular instance it states (for the .h file):

"Could not find directory parent of file [test_MAX31855K.h] with location [MAX31855K_Test\test\utests\test_MAX31855K.h"]

The \file issue did actually exist - funnily enough. But I adjusted to just have \file without the filename appended and nothing changed.

[svenevs]

Hmmmmm ok this seems good, doxygen is now producing valid stuff. I think the path stripping is the problem.

How are you calling doxygen, specifically what do you set STRIP_FROM_PATH as and what do you put for doxygenStripFromPath in exhale_args?

The path stripping logic is probably the cause here, I'm digging around right now....

Are you able to edit exhale (just find exhale/graph.py) and add this:

--- a/exhale/graph.py

Just shoving an error message in to see what's going on, I think the cause of what we're seeing here is something related to how the doxygenStripFromPath gets taken out. When you make html it'll fail with the error message, paste that back here. This one is kind of hard for me to test blindly :/
