XSharp Integration in VS 2019

[leon-ts]

Hi devteam!

I found a problem while editing XSharp code in VS 2019. In the attachment is a screenshot with a visual description of the problem. A further attempt to select a method (typing "oColumn:") displays a list of members of the DataColumnCollection class instead of the DataColumn class.

Best regards,

Hi Leonid,

Do you mean you already have a local (var) named oColumn and then in further nested code you declare another variable with the same name? This is not allowed and the compiler would give you an error anyway.

Hi Chris,

Variables are named differently. The first is in the plural (oColumnS), and the second is in the singular (oColumn without S).

Addition: This code compiles and works. The problem is only with the code editor in VS 2019. I have the same problem with any variable names. It's not about the name.

Best regards,
Leonid

Chris,

No it is the

Code: Select all

VAR oColumn := oColumns[i-1]

where our VS intellisense engine thinks that oColumn has the type of the collection and not the type of the element in the collection. I think Fabrice has to look into this.
Can you make a ticket and assign this to Fabrice ?

Done!

Robert, Chris,

A similar problem is also observed in the following construction:

Code: Select all

LOCAL o AS OBJECT // for sample only
IF o IS DataTable VAR oDataTable
	// some actions with oDataTable
ENDIF

Variable oDataTable is out of sight of Intellisence.

Best regards,

Leonid,
That is a new syntax that we have overlooked in the VS integration.

Thanks Leonid, this is now logged as well: https://github.com/X-Sharp/XSharpPublic/issues/368

Robert, this syntax is very convenient and I began to use it often. Thanks!

Chris, thanks!

Best regards,

A few more issues editing XSharp code in VS 2019.

1. In an expression with several nested function calls, Intellisence displays the parameters of the previous function.
Еxample (invalid, for demonstration only):

Code: Select all

LOCAL c AS STRING
c := RTrim(Str(Val("1")))

When I enter the opening bracket after "RTrim(" the parameters of the "RTrim" function are shown to me, everything is correct. Then I continue to type "Str(" and after the opening bracket I see again the parameters of the "RTrim" function, which is already wrong. Next, I continue to type "Val(" and after the opening bracket, the parameters of the "Str" function are shown to me, which is again wrong. That is, each time the next function is entered, the parameters of the function in front of it are displayed. With the same incorrect effect, hovering mouse over any function in the expression - it displays tooltip from the function located in front of it.

2. The setting "XSharpIntellisenceCommit completition list by typing ..." is not saved if you specify an empty line in the input field. After restarting VS 2019, this setting restores the default value:

Code: Select all

{}[]().,:;+-*/%&|^!~=<>?@#'"

I need autocompletition from combobox only by explicitly selecting an item and pressing Enter. To do this, I deleted all the characters in the above setting. But after restarting VS 2019, the setting is restored. At the same time, the completion is still performed on some characters (for example, the closing bracket), even if not a single character is specified. If I specify any useless character in this setting, then input completion works correctly (only by Enter).

Best regards,
Leonid
