Tips and Tricks

Doxygen / clang-format Oddities

Use "@tag" syntax instead of "\tag" : clang-format doesn't handle these two constructions the same way and, sometimes, may break the structure. It seems that using "@tag" gives more predictable results. Still better, remember : be coherent and do the same thing the same way all the time.
for the same reason, always insert a blank comment line between two blocks of doxygen documentation. This will prevent some Doxygen oddities.

clang-format has problems when handling comments in the same line than code. So, avoid things like this :

avoid this

       if (x >= 0 && x < width) {  // Check if inside the image

this is OK

       // Check if inside the image
       if (x >= 0 && x < width) {

this is OK too

       if (x >= 0 && x < width) {
         // Yes, x is inside the image
