Use react + typescript #69

Closed ericvergnaud closed 1 year ago

ericvergnaud commented 1 year ago

Hey Ter,

I thought I'd step-in before maintaining 'old-style' html/css/js becomes discouraging...

This is a react + typescript version of antlr-lab. I hope you'll find it easier to fix bugs and introduce new features. Typescript is obviously much nicer to use than js.

React is quite straightforward once you grasp the concept:

On the backend I made a small change to fix a CORS issue, and also renamed 'static' to 'web' because the react-built web site contains a 'static' folder, which was confusing.

On the front-end, I've tried to reuse your CSS as much as possible. A few exceptions when using bootstrap components. I made the left-hand presentation a splash screen that can be dismissed, saves screen estate.

I've updated the instructions to make it easy to start.

This runs beautifully here: mvn install, create docker image, run docker image, pretty smooth

I hope you like it.

Let me know if you need help

(I hope you're not affected by the google layoffs...)

Cherry on the cake, you can now manually set the divide between left and right panes ;-)

Can't get it to work.

The current instructions and code work for me. This doesn't. Are there new instructions?

ericvergnaud commented 1 year ago

@kaby76 You need to build the UI first, check the top-level readme

ericvergnaud commented 1 year ago

btw there's a maven plugin for running node/yarn, but let's first check if Ter wants to adopt this

kaby76 commented 1 year ago

After installing yarn the correct way (not the one that Ubuntu recommends; fixed via sudo apt-get purge cmdtest; sudo apt-get purge yarn; npm install --global yarn), and building, it works. The UI is wonderful. Much better to move the instructions, copyright to a splash window.

Wow, thanks Eric! This is incredibly generous. Let me evaluate it. I really have tried to avoid learning these web tool kits though, and I worry about complexity, but let me take a look.

ericvergnaud commented 1 year ago

I'll happily walk you through the code if it helps.

parrt commented 1 year ago

@kaby76 can you send a few screenshots?

BTW, if I resize the LHS pane with the grammars to a narrow column, the vertical separator becomes a jagged line (third picture, the vertical separator normally is in the middle of the window), and I can no longer grab it to resize the LHS pane to make it larger. The code looks nice, though. :) Nice Typescript.

ericvergnaud commented 1 year ago

I can fix that by setting a minimal width to the left pane

kaby76 commented 1 year ago

What is the status of this PR? Is it going to be merged, please? There are bugs in the client code that need to be fixed. https://github.com/antlr/antlr4-lab/issues/74

parrt commented 1 year ago

In the end guys I don't have time nor interest to learn react. I'm having fun with antlr lab as it is and I am completely overwhelmed with open source work, so I'm going to close. Sorry but thanks again for the huge contribution @ericvergnaud !

On the other hand, you guys could always create your own version at a different URL. I would be only too happy to drop an open source project from my list of work. (Note that I would be keeping lab.antlr.org up as my own software for my entertainment when the mood strikes me.)
