Another good reason to use "sizeof(var)" instead of sizeof(type)". :)That is indeed a very good reason, in addition to getting the type right automatically (by virtue of letting the compiler pick it). Should we make this an explicit guideline in our documentation?Better yet: can we create a Coccinelle script to fix it automatically? -StoleeHow about 'Both'. We can't assume all contributors have Coccinelle on their OS/system.
Both is best, but I find static checkers to be more reliable than updating documentation. For that reason, I would prioritize the Coccinelle script over adding another bullet point to the style guide. The PR builds for GitGitGadget run ci/run-static-analysis.sh as a check (see the StaticAnalysis job in [1] for an example). That provides a free way to get feedback for users without Coccinelle.
