OpenFOAM and YouCompleteMe

gaza · September 26, 2018, 04:22

Hi Foamers,
Does anyone use YouCompleteMe vim plugin?

https://github.com/Valloric/YouCompleteMe

Can anyone provide an exemplary .ycm_extra_conf.py file
or tell how to set YCM for OpenFOAM?

Hi
Here you have a plugin that creates .ycm_extra_conf.py

Dear Przemek,

Thanks for posting it. However, I'm not able to make it work.

I went into my OpenFOAM install directory, then ran

PHP Code:


			
$ vim

Inside vim, I ran the following command as suggested here: https://github.com/rdnetto/YCM-Generator#usage

PHP Code:


			
:YcmGenerateConfig

Then it returns the following error:

PHP Code:


			
ERROR: Unknown build system



shell returned 2



Press ENTER or type command to continue

Can you please help regarding what might be the problem?

Hello,

I tried to follow this, but when I run this:

PHP Code:


			
$ ./config_gen.py --verbose -e /opt/OpenFOAM/OpenFOAM-8/applications/solvers/multiphase/interFoam

I am presented with the following error

PHP Code:


			
Found OpenFOAM Make/options

Running wmake...
$ wmake
Build completed in 0.25 sec

Collected 0 relevant entries for C compilation (0 discarded).
Collected 0 relevant entries for C++ compilation (0 discarded).

ERROR: No commands were logged to the build logs (C: /tmp/tmpM5woKM, C++: /tmp/tmpBXTsU7).
Your build system may not be compatible.

It's weird that it still doesn't work for me

, which worked for you & can't find out what might be the error.

I checked my shell environment, according to Wlydckat's blog post that you had mentioned in the GitHub issue :

PHP Code:


			
$ echo $WM_PROJECT_DIR
/opt/OpenFOAM/OpenFOAM-8
$ echo $FOAM_APPBIN
/opt/OpenFOAM/OpenFOAM-8/platforms/linux64GccDPInt32Opt/bin

Please do these steps:
1. load OpenFOAM environment variables
2.

Code:

cd /opt/OpenFOAM/OpenFOAM-8/applications/solvers/multiphase/interFoam

3.

Code:

vim interFoam.C

4. in vim

Code:

:YcmGenerateConfig -e

REMARK: For me it works only in

Code:

$WM_PROJECT_USER_DIR/dirToSolver

In

Code:

$WM_PROJECT_DIR/dirToSolver

I get the same errors as you.

So please try copy interFoam to user directory and than apply the steps 1-4.

Thanks so much! So, this works perfectly now. I wanted this for learning purpose – OOP C++ for OpenFOAM. Imagine how much beneficial it would be to type namespaces like `Foam::` & having these nice autosuggestion (see the attached image). Someone needs vim with these two plugins: youcompleteme & ycm-generator.

I'll be looking forward to get the same with nvim in future.

Only question remains: If all the OpenFoam namespaces are available in this way or only the ones related to interFoam, if someone does copy just one solver (interFoam here) to user directory & generates the required file using ycm-generator.
