Add `ampersand replacement` option #50

Open aDotInTheVoid opened 4 years ago

aDotInTheVoid commented 4 years ago

In the beamer class, one needs [ampersand replacement=\&] to make it work. source

It would be nice if there was an option to do this, or if it was the default. I'm not sure if there is a situation in which this behaviour isn't desirable

I'd be willing to implement this if you could point out the relevant parts of the code.

If we use \& as separator as default, how would one specify a literal & in one of the cells?

aDotInTheVoid commented 4 years ago

Hmm, as I see it there are 3 approaches

I'm not sure which is best.

One of the StackExchange solutions proposes to specify [fragile] on the frame environment. That looks like the cleanest solution. Are there any drawbacks to that?

aDotInTheVoid commented 4 years ago

Not that I know of, so I guess I'll just use that.

Sorry for digging this out again.

See https://tex.stackexchange.com/questions/136240/drawbacks-of-using-fragile-frames-in-beamer:

With fragile every contents is written into an external file and read back. Not a big deal but makes compiling slow.

Apparently the fragile option is incompatible with the allowframebreaks option, without some awkward finagling.

Especially the first point about slow compilation is a valid concern that I share, hence, I am always using ampersand replacement. It would be cool if tikzcd-editor supported this as an output and input (for parsing) format.

Hm... in that case we should allow the user to specify their own ampersand replacement inside the code box. Here are some steps that need to be done:
