Small bug : Nil is preserved in Pascal->JS |
Thu, Nov 12 2020 12:40 PM | Permanent Link |
erickengelke | I've started trying compiling library code and ran into a small bug.
var x : variant; begin x := .... if x = Nil then exit; generates if (x == Nil) return I believe it should test x == Null A quick look through the compiled JS shows that several library statements in Webcomps.Tlocation.... also evaluate to testing against the undefined Nil Otherwise, I see that enforcement of casting during assignment is done, which is a good thing. I like the typing completion features. Lots to like! Erick EWB Programming Books and Component Library http://www.erickengelke.com |

Also, assigning Nil to a variable is impossible and generates a runtime error, but you can assign NULL_VALUE which works as a workaround.

erickengelke | Also, dataset's GetColumns functions generates an error for me on a well defined TDataSet. In 2.x it created a nice string.

erickengelke | Finally for today, THTMLLabel's no longer have a dblclick handler, that was a handy thing to have. Not sure why its omitted.
