Well, it turns out, C++ wants to support architectures, where data and instruction pointers are physically distinct […]
qsslint – A linter for Qt stylesheets
Enter the wonderful world of tools for which the announcement blog takes more time to write than the tool itself. qsslint is a small command-line utility for verifying the syntax of your Qt stylesheet files (*.qss). It’s much like KDAB’s previous linter contribution, qmllint. It simply returns 0 if the stylesheet is valid, and non-zero […]
