mmt to csv converter

powered by electron, angular, nodejs, typescript

Introduction

mmt to csv converter desktop application made using electron, Angular, Nodejs

what are moment or .mmt file ?

moments file is a binary file format used for transport/storing radar generated gaussian moments in an electronic form. It is L2 level data with necessary information to derive parameters.

How this app helps you in saving a lot of coding time

moments file or .mmt file are L2 level data products which must undergo further computation processing to derive necessary U, V, W, Direction data products which have great value for scientific research. Previously researcher/scientific groups would invest professional time in uderstanding the format and implement code to read these .mmt files.

This application will help you in transforming .mmt files to standard scientific friendly .csv files, which the reasercher can analyse output using tools and languages of their own interest.

The generated .csv file are called L3 level data products with fields height, U, V, W, Direction, Zenith SNR, Zenith doppler.

The starter electron+angluar bootstrap is taken from here. Thanks to maximegris for his wonderful work in bootstrap.

release info

• can validate and inspect operation to get mmt file info
• can convert mmt file csv file to an output folder
• error handler with with responsive acknowledgement

If you are a python/nodejs developer, you can scroll futher. :)

Getting Started

setting python environment

make sure virtualenv is installed to generate python environment folder venv and install python numpy module.

$ virtualenv ./pyscripts/venv
$ activate
(venv)$ pip install cx-Freeze

building python scripts to exe files

#Navigate to pyscripts folder and activate python environment
$ .\venv\Scripts\activate

#later execute the build command
$ python setup.py build

setting node environment

Clone this repository locally:

git clone https://github.com/jeldikk/mmt-csv-converter.git

Install dependencies with npm (used by Electron renderer process):

npm install

There is an issue with yarn and node_modules when the application is built by the packager. Please use npm as dependencies manager.

If you want to generate Angular components with Angular-cli , you MUST install @angular/cli in npm global context. Please follow Angular-cli documentation if you had installed a previous version of angular-cli.

npm install -g @angular/cli

Install NodeJS dependencies with npm (used by Electron main process):

cd app/
npm install

Why two package.json ? This project follow Electron Builder two package.json structure in order to optimize final bundle and be still able to use Angular ng add feature.

To build for development

• in a terminal window -> npm start

Voila! You can use your Angular + Electron app in a local development environment with hot reload!

The application code is managed by app/main.ts. In this sample, the app runs with a simple Angular App (http://localhost:4200), and an Electron window.
The Angular component contains an example of Electron and NodeJS native lib import.
You can disable "Developer Tools" by commenting win.webContents.openDevTools(); in app/main.ts.

Project structure

Folder	Description
app	Electron main process folder (NodeJS)
src	Electron renderer process folder (Web / Angular)

Add a dependency with ng-add

You may encounter some difficulties with ng-add because this project doesn't use the defaults @angular-builders.
For example you can find here how to install Angular-Material with ng-add.

Browser mode

Maybe you only want to execute the application in the browser with hot reload? Just run npm run ng:serve:web.

Included Commands

Command	Description
npm run ng:serve	Execute the app in the browser
npm run build	Build the app. Your built files are in the /dist folder.
npm run build:prod	Build the app with Angular aot. Your built files are in the /dist folder.
npm run electron:local	Builds your application and start electron
npm run electron:build	Builds your application and creates an app consumable based on your operating system

Your application is optimised. Only /dist folder and NodeJS dependencies are included in the final bundle.

E2E Testing

E2E Test scripts can be found in e2e folder.

Command	Description
npm run e2e	Execute end to end tests

Note: To make it work behind a proxy, you can add this proxy exception in your terminal
export {no_proxy,NO_PROXY}="127.0.0.1,localhost"
