2021-05-14Improve loplugin:stringviewStephan Bergmann
Issue the "instead of O[U]String, pass [u16]string_view" diagnostic also for operator call arguments. (The "rather than copy, pass subView()" diagnostic is already part of handleSubExprThatCouldBeView, so no need to repeat it explicitly for operator call arguments.) (And many call sites don't even require an explicit [u16]string_view, esp. with the recent ad48b2b02f83eed41fb1eb8d16de7e804156fcf1 "Optimized OString operator += overloads". Just some test code in sal/qa/ that explicitly tests the O[U]String functionality had to be excluded.)

2021-05-14Improve loplugin:stringview diagnostic outputStephan Bergmann
Say what the O[U]String is constructed from (to make it easier to decide on an optimal rephrase of the whole surrounding expression), and find more cases that could use O[U]StringChar.

2020-11-19Simplify loplugin:stringviewStephan Bergmann
(It is conversions from certain string expressions, like empty strings or copy calls, to string view we are interested in, wherever they happen to occur. Though this didn't find any additional occurrences to flag now.)

2020-11-11loplugin:stringviewNoel
Add new methods "subView" to O(U)String to return substring views of the underlying data. Add a clang plugin to warn when replacing existing calls to copy() would be better to use subView().
