# M-tools

A collection a useful tools for building queries in the Power Query Formula Language ("*M*") used by [Microsoft Power BI](https://powerbi.microsoft.com/).

## Usage

>Power BI does not (appear) to currently support external dependencies so setup is a little rudimentary.

1. Create a new blank query.

2. Copy the content of [M.pq](M.pq) to this query using the advanced editor.

3. Name the query `M`.

Functions may then be access from other queries as records on `M`. For example, `Pipe` may be invoked as:

    M[Pipe]({functionA, functionB, ...})

## Contributing

Do not directly edit [M.pq](M.pq). This is built from the components defined in

[src/](src/). It is provided, preassembled for convenience only.

To add functions, create new `*.pq` files within [src/](src/) containing the

expression body and any relevant documentation (see the other files for

reference). When compiled, the expression will be bound to the name of the file.

### Building

```bash

runhaskell build.hs

```
