Interpolated Strings

Post by FFF »

Guys, Wolfgang,
just found "the" thing about interpolated strings, and thought maybe i'm not the only one a bit slow ;)

VAR i:= 4 AS INT
VAR c AS STRING
c:= i"Bla {i} blabla"

i.e.: the syntax allows to insert ANY type into a string, handling silently the conversions! That's really cool.

Even something like
c:= i"Bla {oMainWindow} blabla"
works, inserting the classname.

So you might consider adding/adapting the docs, as up2now the samples insert only strings, which is relatively pointless ;)
Karl

Hi Karl,
Currently I am on holiday, will add better samples after my return.

Hi Karl,

I'm eagerly waiting for the next C# feature to become true.

local dw as dword

dw := 12_123_789

instead of the boring

dw := 12123789

;-)

regards

Could it be that you didn't get the drift of my post?
All samples i saw for i"..." used strings as insertion, and that is really old, as i can do the same with simple +...+, so i never understood the usecase :)
But for any other type it comes handy...

? 12.22 + " " + today() + " " + setcentury() + " " + 12123789

Maybe even that will work someday ;-)

? 12.22 + " " + today() + " " + setcentury() + " " + 12_123_789

That all works (but only) for "?"...

Mmm, that (underscore delimiters inside numeric literals) should not be too difficult to implement I think.
I'll see what I can do.

I use this a lot. I have an old C# application built around datasets and i use this when building sql strings.

plInfo.SqlUpdate =
$@"UPDATE {Const.TBL_PRICE_LIST_STRUCT}
SET
{Const.COL_COLUMN_NUM} = {dataReader.SqlValueString(Const.COL_COLUMN_NUM)}
,{Const.COL_START_POSITION} = {dataReader.SqlValueString(Const.COL_START_POSITION)}
,{Const.COL_END_POSITION} = {dataReader.SqlValueString(Const.COL_END_POSITION)}
,{Const.COL_IS_ACTIVE} = {dataReader.SqlValueString(Const.COL_IS_ACTIVE)}
,{Const.COL_IMPORT_FORMAT} = {dataReader.SqlValueString(Const.COL_IMPORT_FORMAT)}
,{Const.COL_EDIT_UID} = {dataReader.SqlValueString(Const.COL_EDIT_UID)}
,{Const.COL_EDIT_DATE} = '{YYYYMMDDHHMMSS}'
,{Const.COL_CREATE_UID} = {dataReader.SqlValueString(Const.COL_CREATE_UID)}
,{Const.COL_CREATE_DATE} = {dataReader.SqlValueString(Const.COL_CREATE_DATE)}
,{Const.COL_PRICE_FORMAT_NUM} = {dataReader.SqlValueString(Const.COL_PRICE_FORMAT_NUM)}
WHERE {Const.COL_PLS_NUM} = {dataReader.SqlValueString(Const.COL_PLS_NUM)}";
