When a double is neither greater nor lesser, is it equal ?
This is assumed in some implementations like for RTL’s VarCompareValue and other function that return the result of the comparison.
In those function you can see code like (more…)
Just pushed a few changes to the DWScript repository for compatibility with the just released Delphi 11 Alexandria.
The only change required was related to a fix of the Delphi compiler, which now properly has integer overflow checks controlled by $OVERFLOWCHECKS while they were previously controlled by $RANGECHECKS.
I also added support for the Delphi 11 dialect for binary literals (starting with %). DWScript already supported binary literals with the “0b” prefix since 2012 (as in C), I had been hoping the % symbol would not be sacrificed for this purpose, but oh well. (more…)
Just a word of warning about a recent commit that added support for nested types in DWScript.
This support is at the moment only enabled in class declarations, and very minimally tested, a lot more testing is required – and welcome 🙂 – before it can be considered safe to use, and extended to other type declarations.
The related code should only kickoff if a “type” keyword is encountered in a class declaration (which would previously be reported as an error), so the change should be innocuous to existing code.
SQLite offers through its JSON1 extension a lot of capability. Generating JSON outputs from SQL, even complex structured, multi-level JSON is very straightforward.
But what about the opposite use case ? When you have store data as JSON in an SQLite database, and you want to search or filter it ? This is a short exploration of what to expect.
We all need more battery life, and for quad-core i7 & i5, a simple way to gain more battery is to simply turn off extra cores.
This little setting for Windows 10 made a whole world of difference in my experience, with battery life literally doubled on my core i7, and almost 50% gains on another i5 laptop.
