Count single, double and tripple bonds in a molecule?

Is there a way using cxcalc or evaluate (or something else) to separately count the number of single, double, and triple bonds in a molecule?

i was trying to use evaluate's count(filter(...))   but could not figure out how to just filter by one kind of bond. 

I am aware of the stereoDoubleBondCount, but that does not count all double bonds so not quite what i am looking for.

Any help would be much appreciated

The matchCount() Chemical Terms function can be used to count single, double, and triple bonds.

Example:

$ evaluate -e "matchCount('*-*')" "CC\C=C\C=C\C#CCC"

6



$ evaluate -e "matchCount('*=*')" "CC\C=C\C=C\C#CCC"

2



$ evaluate -e "matchCount('*#*')" "CC\C=C\C=C\C#CCC"

Thanks for the reply, however this does not seem to take into account aromatic rings

ie:

evaluate -e "matchCount('*-*')" "CC1N(CC2N(CCC3=CC=CC=C23)C1=O)C(=O)CC#C"
14

evaluate -e "matchCount('*=*')" "CC1N(CC2N(CCC3=CC=CC=C23)C1=O)C(=O)CC#C"
2

evaluate -e "matchCount('*#*')" "CC1N(CC2N(CCC3=CC=CC=C23)C1=O)C(=O)CC#C"
1

is not taking into account the 3 single/3 double bonds from the aromatic ring

Any way to include those?

The 3 single and 3 double bonds in the aromatic ring are considered as aromatic bonds. We think this is the correct approach.

Aromatic bonds can be counted as well:

$ evaluate -e "matchCount('[*,#1]:[*,#1]')" "CC1N(CC2N(CCC3=CC=CC=C23)C1=O)C(=O)CC#C"
