Just plain snippets are often difficult to understand without examples or some explanation
That's were a good "snippet manager" makes all the difference.
Borland (when they actually produced developer tools) had a very nice snippet manager. Each snippet could have...
- Text description
- Hierarchical category
- Email address
The tool allowed browsing and searching. I think it even had support for keyboard-shortcuts and a "put the cursor here" marker. You could then have short snippets like this to save typing (the vertical bar was automatically removed and the cursor put in its place)...
if ( | )
I suggest the first candidate snippet should be Blink without Delay!
That's why I like the playground
I think there is a gap between the included examples and the Playground. It is difficult for the community to contribute to the included examples (is it even possible?) and the playground is just too "heavy" for some things.
