Isn’t that basically emacs with evil mode?

Yes, the 80% claim comes from comparing 9 tests converted by both the conversion tool and humans and comparing the quality - “80% of the content within these files was accurately converted, while the remaining 20% required manual intervention.” Not sure what to make of it since they claim only 16% of files get fully converted.

Was it the 20% of the code that requires 80% of the time to write?

I guess they believe the files that didn't get fully converted got like 76% converted on average?

The conversion is between two testing libraries for React. Not to be too cynical (this sort of works seems to me like a pretty good niche for llms), but I don’t think I’d be that far off of 80% with just vim macros…

I think you're significantly underestimating the complexity of automatic transforms. It's not like they didn't try writing codemods first, and vim macros aren't more powerful than codemods.

You really think you could achieve 80% success rate with just syntaxic transformations, while the article says they only reached 45% success rate with fine grained ast transformations?

I am no vim hater, but allow me to cast a large, fat doubt on your comment!

Fair enough :) It was very much an exaggeration. But, I do wonder how far would “dumb” text editing go in this scenario. And, more importantly, whether it wouldn’t be faster overall than writing a tool that still requires humans to go through its output and clean/fix it up.

You might be underestimating vim ;)

Key point is that vim macros are interactive. You don’t just write a script that runs autonomously, you say “ok, for the next transformation do this macro. Oh wait, except for that, in the next 500 lines do this other thing.” You write the macro, then the next macro, adjust on the fly.

From the article:

> Our initiative began with a monumental task of converting more than 15,000 Enzyme test cases, which translated to more than 10,000 potential engineering hours

That's a lot of editing.

Out of curiosity, can you drop into edit session during the macro? It is some time since I last used vim, so I do not recall, but in emacs you can record a macro along the lines of "do A, do B, drop to edit session letting user do whatever, do C, do D". Is that possible with vim macros?

I don't think so since you need to leave edit mode to terminate the macro.

That sounds interesting! Would you mind sharing some links to the articles or videos that focus on this possibility?

This Vimcast (http://vimcasts.org/episodes/converting-markdown-to-structur...) recording is an example of a quite complex macro for converting (a specific file's) markdown to HTML. At the beginning of the video you see that they save the macro to the "a" register. You can record macros of similar complexity to each of the other letters of the alphabet, to get some idea of the maximum complexity (though I tend to stick to about 3 or less in a single session).

Not to mention the possible savings if you just don't switch to whatever the latest testing framework is your resume driven developers want. 100% time savings!

Enzyme is abandoned and doesn’t work on newer versions of React. Many teams are doing this conversion for their React apps.

Gee, if "many teams" want to spend their time migrating their unit-test framework and unit tests because their frontend framework hit version 18 I suppose that's their prerogative.

Not me to applaud Teams but it seems Slacks lunch is being eaten by people who are busy building things on the corpse of Skype, not churning through churn incarnate.

If Enzyme was at all popular (which it sounds like it was) I'm surprised no one from the community has taken over maintenance.

I agree, once I had to write a groovy conf out of java library constructors and setters and vim macros were really good for that.

You can file a suit against anybody for anything. If it’s obviously without merit, it’s likely to get dismissed pretty quickly. But there’s nothing stopping you from filing it.

I don’t think the specifics of the placement matter all that much. I’m a happy nvim user with a dvorak layout. Only ‘h’ is on the home row, but it’s not a problem. The issue with normal arrow keys is that you have to lift your whole hand to reach them, which is way less precise and much slower than just moving a finger.

Incredibly enough, you can also talk to people in person. Does wonders.

From my experience, the best performing companies foster a culture of ownership. Owning the features/products you work on, the team you work with, and, to some extent, the company as a whole. The other limit is a completely detached and mercenary workforce. This is also a part of the reasoning behind ESOPs.

The fact that those people didn’t feel like they had any other way of voicing their disagreements with the company’s direction (and having them heard), does not bode well for the long term future of Google. Loosing passionate people that care deeply enough about your company to criticize it is seldom a good thing.

I think it’s pretty clear the comment was referring to the partition of the sudetenland, which Poland was absolutely a (albeit minor) participant in. But thank you for linking the article. I’ve always kinda assumed that Poland was given the territories by the Nazis as a way to spread the blame. Turns out they demanded it themselves outside of the Munich conference.

I don’t know how much this is bias on my part, but sending weapons to Gaza feels more equivalent to arming anti-russian partisans in the alternate reality where the march on Kyiv wasn’t a failure and the Ukrainian government collapsed.

It’s not a disorder if it’s not sufficiently disruptive :-) There are no absolutes in psychology.
