Enter the wonderful world of instruments for which the announcement takes more time than the instrument itself.
qsslint is a small command line utility for checking the syntax of your Qt stylesheet (*.qss). This is very similar to the previous KDAB contribution, qmllint . It simply returns 0 if the stylesheet is valid, and nonzero otherwise.
Don't get me wrong, the author doesn't like CSS and doesn't want to encourage its use. But if you can't get away from it, then at least use a parser to catch errors at compile time, not during production.
The suggested way to use these tools in your daily life is not to use them manually. Instead, include them in your build system or CI and forget about them until the developer makes a typo.
Also, use the same advice for each source file type. Whether it's XML, JSON, or QML, there are many parsers available. And finally, for C++, the compiler already checks the syntax for you, but now you can also check Qt semantics with clazy or get extended C++ diagnostics with clang-tidy .
