Zip up Rule directories and unzip on demand #252

I can see this is at least partially implemented. Should I be able to set the Language preference from a web assembly and then process MathML? I've made a stab at creating a basic wasm/javascript interface: https://github.com/brichwin/MathCATForWeb/ If I try to set the If I don't set the <!DOCTYPE html>

Ah, okay. I'm a little bit more awake now and realized it doesn't look like my calls to
Since I can compile the MathCATDemo project and that works I'm guessing that my MathCATForWeb isn't configuring the build of MathCAT correctly to trigger all the right conditional compiles. |

Looks like I didn't check in the latest thing I found I could do in Cargo.toml: I think you want to add Because I didn't publish the latest version which has the zip file fixes, you can't use directly refer to 0.6.4 from another project. But this "patch" feature allows you to get around that by telling Rust not to looking in crates.io for a published version. I'm not 100% sure I have the syntax right. I copied and modified it from some Rust documentation. That might help. |
Each language file is about 500k. As the number of languages gets bigger, this is means a substantial size increase for MathCAT.
There is a huge amount of compression that can happen when these are zipped up. Typically, only one or two languages will get used, so zipping up each language directory can save a lot of space.
Implementation ideas:
._Rules.txtfile that has the rules listed, one per line (SimpleSpeech, ClearSpeak).The text was updated successfully, but these errors were encountered:
