cannot find namespace in d.ts

[kaktus40]

Hello,
in alasql.d.ts you change :

declare var alasql: alaSQLSpace.AlaSQL;

for

export declare var alasql: alaSQLSpace.AlaSQL;

with the export declaration, typescript can't use the definition in the file. I have this error:

error TS2503: Cannot find namespace 'alaSQLSpace'.

Is it possible to revert to the previous version please?

Interesting...

The change came from #752 where the point is to be able to do a

import * as alasql from "alasql"

rather than roling it back I suggest we look into why namespace 'alaSQLSpace' is not found. It might be because the namespace is not also public (exported)

I have made a change to https://github.com/agershun/alasql/blob/develop/dist/alasql.d.ts - but have no way to test it. Could you test the new file and let me know if it made it better?

with the following it's OK:

// Project: https://github.com/agershun/alasql

declare namespace alaSQLSpace {
    interface AlaSQLCallback {
        (data?: any, err?: Error): void;
    }

    interface AlaSQLOptions {
        errorlog: boolean;
        valueof: boolean;
        dropifnotexists: boolean; // drop database in any case
        datetimeformat: string; // how to handle DATE and DATETIME types
        casesensitive: boolean; // table and column names are case sensitive and converted to lower-case
        logtarget: string; // target for log. Values: 'console', 'output', 'id' of html tag
        logprompt: boolean; // print SQL at log
        modifier: any; // values: RECORDSET, VALUE, ROW, COLUMN, MATRIX, TEXTSTRING, INDEX
        columnlookup: number; // how many rows to lookup to define columns
        autovertex: boolean; // create vertex if not found
        usedbo: boolean; // use dbo as current database (for partial T-SQL comaptibility)
        autocommit: boolean; // the AUTOCOMMIT ON | OFF
        cache: boolean; // use cache
        nocount: boolean; // for SET NOCOUNT OFF
        nan: boolean; // check for NaN and convert it to undefined
        angularjs: boolean;
        tsql: boolean;
        mysql: boolean;
        postgres: boolean;
        oracle: boolean;
        sqlite: boolean;
        orientdb: boolean;
    }

    // compiled Statement
    interface AlaSQLStatement {
        (params?: any, cb?: AlaSQLCallback, scope?: any): any;
    }

    // abstract Syntax Tree
    interface AlaSQLAST {
        compile(databaseid: string): AlaSQLStatement;
    }

    // https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/es6-promise/es6-promise.d.ts
    interface Thenable<T> {
        then<U>(onFulfilled?: (value: T) => U | Thenable<U>, onRejected?: (error: any) => U | Thenable<U>): Thenable<U>;
        then<U>(onFulfilled?: (value: T) => U | Thenable<U>, onRejected?: (error: any) => void): Thenable<U>;
        catch<U>(onRejected?: (error: any) => U | Thenable<U>): Thenable<U>;
    }

    // see https://github.com/agershun/alasql/wiki/User%20Defined%20Functions
    interface userDefinedFunction {
        (x: any): any;
    }
    interface userDefinedFunctionLookUp {
        [x: string]: userDefinedFunction;
    }
    // see https://github.com/agershun/alasql/wiki/User%20Defined%20Functions
    interface userAggregator {
        (value: any, accumulator: any, stage: number): any;
    }
    interface userAggregatorLookUp {
        [x: string]: userAggregator;
    }

    interface AlaSQL {
        options: AlaSQLOptions;
        error: Error;
        (sql: any, params?: any, cb?: AlaSQLCallback, scope?: any): any;
        parse(sql): AlaSQLAST;
        promise(sql: any, params?: any): Thenable<any>;
        fn: userDefinedFunctionLookUp;
        aggr: userAggregatorLookUp;
        autoval(tablename: string, colname: string, getNext?:boolean): number;
    }
}

declare var alasql: alaSQLSpace.AlaSQL;
declare module 'alasql' {
    export = alasql;
}

@jnath should test if it's ok for him.

[mathiasrw]

@jnath any chance you can test if this is working for you?

[mathiasrw]

@jnath have you had a change to check the version provided by @kaktus40 ?

[kaktus40]

I don't like to process like this but is it possible to put my proposition into the next release of alasql. 24 days without answer of @jnath....

[mathiasrw]

Good point. Lets role it back.

@jnath I will role your change back - please comment on this issue when you are back so we can work together to find a solution that fits the usage of both of you...
