Is there an easy way to diff between two Mathematica code extracts that ignores indentation and spacing?

(and line breaks most importantly)

@KraZug in mma?

Maybe.

Can someone please tell me how to make this list {{a1, a2}, {b1, b2}, {c1, c2}, {d1, d2}, {e1, e2}} from this list {{a1, a2}, {{b1, b2}, {c1, c2}, {d1, d2}}, {e1, e2}}. I think that Flatten with second argument might do the trick, but I am not sure how to do that.

@Moonwalk Flatten it down completely and use Partition to rebuild the tuples.

@halirutan Thanks! I will do that.

@Kuba, in anything.

In particular, I was trying to compare between a piece of code copied from Mathematica and a piece that I had edited in IDEA, which I'd changed the spacing and line breaks etc on.

@KraZug Maybe turning both pieces into their FullForm string and look at this difference?

@KraZug Or you could ReadList[file, Hold[Expression] and compare using linked solution.

I was hoping for something like a full diff tool, where I can see both side by side and differences highlighted. I did use an online one which would ignore whitespace but not line breaks

@KraZug Have you tried IDEA's diff?

@halirutan, no, didn't realise there was one.

@KraZug Use Ctrl+Shift+Alt+Insert to create a new scratch file

Copy your first code there, then create another scratch file for the second code.

If you select the portion of code an press Ctrl+Shift+Alt+Insert, IDEA will create a scratch file from this portion automatically.

Then you see on the left in the project view (Alt + 1, if it is not open) the two files

Select both and press Ctrl+D or right-click with the mouse and "Compare Files"

@halirutan, thank you, that is exactly what I was after

@KraZug I hope you are using the beta-release of the Wolfram IntelliJ plugin?

@KraZug How to install the new beta release

@halirutan, I'm using a version of the plugin, it might be an older version

@KraZug OK. The versions < 3 are breaking down in newer IDEA versions. So it's worth using the new beta.

Ok, I'll make sure I update. My IDEA has been bugging me to update

@KraZug Just download the latest Community edition and replace your old one.

Ok, I will do

Any other really useful features I should know about as well as the diff tool?

Well, is there any information about that new functions about 11.2?

@yode 11.2?

Do you mean 12?

@xzczd, I have found my code for the case where I needed to include ghost points in my method of lines, can we create a chatroom to discuss?

@KraZug ghost points? sounds spooky

@KraZug Let's disscuss in this room: chat.stackexchange.com/rooms/88018/…

👻

@kuba You think it's possible to find all the MMA functions that haven't had any questions asked about them? The inverse of duplicate searching ;)

@ChrisK lol I was thinking something along the same lines...

I bet @Szabolcs could have his very own episode

@CarlLange admittedly has had good luck getting interesting questions answered on the streams

I mean better than talking to Stephen would be talking to actual developers

I just tried to fast-forward through the stream that is playing in real time -___-

Clearly I don't watch many of these

@ChrisK, shall someone suggest it in the chat then?

@KraZug we'd need to suggest it in a way that they'd be more amenable...

Maybe something like a Q/A session for some long-standing issues the general community is concerned about?

@KraZug IDK, maybe we could compile a list of desired features / areas for improvement and go from there

well if we had a designated session in mind, then we could organise a list.

Yeah, he tends to be quite good at responding to the chat.

I suspect they might be amenable to a Q&A livestream if you framed it the right way

@CarlLange That would imply knowing what is the answer to all unanswered questions, wouldn't it? :)
