Static check of identifier length [message #760065]

Hi there,

Could not find anything that comes near to what I need.

We're using eclipse/cdt for embedded SW development with C.

We have some coding rules that limit the length allowed to be used for any identifier (variable, function, macros). Is there a way to add a style check for this rule to be checked while entering code. Just like the static code analysis.

If not I would create something like that. I'm really starting with creating stuff for eclipse. Until now everything was about configuration.
Whats best approach in terms of effort and user experience:
-> Extend the static code analysis functionality
-> Create a plugin that does the check

Thank you for your help,
Hanno.

There is CODAN (integrated static code analyser) rule to check function names
Preferences->C/C++->Code analysis->Coding style: Name convention for functions

You can replace the default regexp with
^.{1,15}$

This would limit the function name length to 15 characters.
If you need code style checkers for variables, macros etc. you must create your own CODAN checker.

Thank you Axel.

Next week I start adding the code checkers for our identifier naming rules.

Additionally there is the persistent request for a display of the text selection length. Embedded inside the bottom bar, right beside the current cursor position.
I don't think there is something like that in eclipse, am I wrong?

Once again thanks.

I don't think this feature is implemented. But it sounds cool. When you open a bugzilla request I would add my vote.
