Build a complete chat system

ChatRev is a server/client chat system, similar to IRC (but much simpler), developed in LiveCode. It was made almost ten years ago by Björnke von Gierke as a proof of concept. Since then he updated it regularly and it is still used daily by him and a few other people to chat about LiveCode and the world.

You can join the discussion or just look at the code by downloading it.

Create QR Codes

John Craig uses LiveCode to directly generate QR codes.

Build a tiny web server

Andre Garcia used LiveCode to build a tiny web server. It serves both static files and LiveCode CGIs. It isn't meant to replace a full-blown web server but has proved useful for many specific tasks like issuing serial numbers via email and monitoring the status of remote computers.

Build a mobile trivia game

Alistair Campbell organised a trivia party with some friends. He wanted a different way to organise the questions so decided to write his own app in LiveCode. I'll let him tell the story:

"The most interesting thing for me was that in that day of LiveCoding I decided that this really needed to be delivered as a mobile app. I had not used LiveCode for mobile development before so I thought this might be a really big ask. In fact, it was incredibly easy. So, right now, I have a working Android app that sits on my phone."

Build an assembly language interpreter

When Andre Garzia was taking the “Computer Architecture 101” class of his Computer Science degree, he had to submit assignments in assembly language. The university used a tweaked assembly language interpreter that was x86 like. It was an educational interpreter made for D.O.S. It wouldn't run on his Macbook Pro.

So he decided to build his own assembly language interpreter with LiveCode. It needed to mimic the one used by the university and he decided to only implement the minimum code needed to run the examples from the course text book. In less than a day, Andre had the app running. It could execute assembly programs line by line which is a boon for learning.

Help navigate a boat

Paul Hibbert recently attended a boating course, I'll let him tell the story.

"During the boating course they taught how to do chart plotting calculations manually using a regular calculator. The potential for a LiveCode app to make life easier soon became obvious, so after an evening of playing around with some code I came up with a nautical calculator app on my PC.

The next stage was getting the app onto my iPhone. The LiveCode Mobile Development Beginners Guide by Colin Holgate was an invaluable resource, it just took away all the uncertainty and answered all of the questions I came up against.

After a few more evenings reading Colin's book, the app was on my iPhone ready for the next boating lesson, my homework was a breeze after that and I passed the course with ease."

Generate tiled images

Jacqueline Landman Gay's business is programming with LiveCode and usually she's working on client projects. She also uses LiveCode to produce small utilities that are quick to make and solve some little personal need.

For instance, she uses a lot of tiled images in different projects. She wrote this quick utility in LiveCode to select an image and see how it looks when it's tiled. The whole working part of the app is only 8 lines of code.

Get the exact details of a colour from your screen

Andy Piddock wanted a better colour picker to use when he was developing web pages. He wrote one in LiveCode for his own use. His colleagues and friends kept asking him where they could get a copy, so he made available, free of charge at Point and See.

Mirror or Reverse text

René Micout built this simple application in LiveCode for a friend who needed to regularly mirror text.

Jacqueline Landman Gay also wanted to reverse some text. She put together this 5 line script in under a minute to do so.

Help you decide where to hang your paintings

Devin Asay's house had an oddly-shaped wall in the living room. His wife wanted to hang some art on it. She was having a hard time visualising how it would look, so he spent an evening measuring the wall and creating this LiveCode stack that let her try out different prints at various sizes and arrangements. (She eventually settled on the Monet garden print shown in the center.)

I asked Devin which took longer, measuring the wall or writing the LiveCode App? He replied "About the same I think. The wall was over a stairway and about 15 feet high at the peak. Durn near kilt myself!"

Keep up-to-date with the weather

Jacqueline Landman Gay wanted to know get continuous updates on the weather so she wrote a LiveCode app that she could leave running on her desktop. The app lets her set the maps she wants to see and the time between updates.

Jacqueline continues "I wrote this before you could get internet weather everywhere you went. I remember leaving it running during a terrible thunderstorm one time, updating every five minutes and watching the deluge roll in."

Get your facts in order

Roger Guay used LiveCode to create InfoMatic, a personal "3X5 card index/file". Major categories are created and selected from the file menu, in this example, Amazing Facts. Cards are dragged and stored into baskets. Clicking on a basket will bring up an option menu of the cards stored therein. The Tools palette allows new cards and baskets to be created, as well as an Export Text feature which creates a text file of the whole category.

Integrate a slideshow viewer

When developing applications for her clients in LiveCode, Jacqueline Landman Gay often needs a quick way to see the contents of a folder of images without having to leave LiveCode and launch a big graphics program. She wrote this LiveCode applet that runs directly in the LiveCode development tool to cycle through all the images.

Jacqueline adds "While it's running the translucent panel disappears so you can see the whole image. The applet is resizable so I can see how the images would look at different dimensions."

Plan your journeys

John Dixon uses LiveCode to drive Google maps to get directions and calculate distances from A to B.

Keep a track of your music

René Micout keeps a track of his vinyl, CDs and digital music with LiveCode.

Teach your child games programming

Andreas Klostermaier is using LiveCode to teach his young son programming. 

He says "His title artwork might be more promising than the gameplay can hold up to, but I like his absolutely fantasy-full, playful and funny approach to game design. I will never forget his eyes, when his hand painted graphics showed up on the iPad screen for the first time!"

Help your children learn maths

Andy Piddock want to help his 4 and 7 year old boys learn maths. So he built a small and basic maths helper in about 40 minutes with LiveCode.

This version is for addition and subtraction but Andy says multiplication and division could be easily added.

Write asteroids

Mike used LiveCode to write his own version of asteroids.

Work out how to build a pyramid

Andreas Klosermaier was doing a Minecraft project with his son. They wanted to build a pyramid as the ancient Egyptians did (no cheating, real crafting!). They used LiveCode to calculate the resources required for different sizes of pyramid. The point was to find out if they could actually accomplish such a venture in any reasonable timeframe.

I'll let Andreas continue "As you can see from our background image, we were developing some doubts about it when we reached the third level. Meanwhile we have reached level 34."

Remember where you parked your car

Simon Asato has to use on street parking. Because the streets are crowded, he might need to park his car some distance away. He built a small app in LiveCode that lets him drop a pin onto a map so that he can always easily find his car.
