Metrics -extension: Most columns are NULL in database table metrics

[mniemela]

After executing CVSAnalY with Metrics, most of the columns in database table metrics are null. Is this a matter of stuff not being implemented, or is there a bug?

To execute Metrics extension, you have to install first sloccount, cccc and python-metrics packages. All of them are in Debian.
Please check if you have them installed.

Maybe this should be documented in a good way.
We need several tools:

• kdsi
• halstead
• mccabe
• pymetrics
• cccc
• sloccount

For details have a look at https://github.com/MetricsGrimoire/CVSAnalY/blob/master/pycvsanaly2/extensions/Metrics.py and search for "find_program".

Looks like the Mccabe metrics for Java is not implemented. So if you are analyzing Java source files, those columns will be empty

I added a small chapter about this tools into the readme: a6b09b9
Sadly i can`t find (fast) the links of mccabe, halstead and kdsi tool.
Do you know where this is located?

@linzhp: You are right. Metrics for many languages are not implemented. Maybe this kind of implementation needs refactoring as well. But feel free to add new languages :)
I will be happy to review it.

@mniemela: Does this help?

[linzhp]

I am implementing mccabe for Java. Checkout https://github.com/linzhp/CVSAnalY/tree/mccabe_for_java. Will create a pull request once it's done.

Btw, where can you find kdsi and halstead for debian? A quick googling session didn't find those packets.

@mniemela Try with the cmetrics bundle (https://github.com/MetricsGrimoire/CMetrics)

[sduenas]

@linzhp Thanks! Sounds great!

[mniemela]

Also, maybe Metrics should print some error if the additional packages haven't been installed?

[andygrunwald]

Good idea. Can you create a PR for this?

Hmm, it looks like there are printouts for situations when programs are not installed. However, for some reason I didn't get them when running Metrics.

@sduenas does CMetrics provide kdsi, halstead and mccabe executables?
