Saving should trigger a file download about vim.wasm

[rhysd]

I agree. But vim.wasm is not in the phase for now. I'm now trying to fix/improve base implementations to make vim.wasm run faster/more robustly. I want to extend fundamental features like :write you're pointing after current fixes are done.
Anyway, thank you for reporting this. To keep your idea in my mind, I'll label this issue as 'enhancement'.

i was going to ask something like this, so my question is how can i get what i write?, i mean if i want to use what i write for an API, for example

Possible implementation would be:

1. Implement a JavaScript function which is supposed to be called at writing a file. In the function, we can show dialog or do something.
2. In C, :write is implemented in do_write() function of ex_cmds.c. Call above JavaScript function in do_write() with the file name and the buffer content

After some thoughts, I implemented :export special command to download current buffer or specific file at 4c81d4c.

I did not hook :write because browser does not overwrite existing file (e.g. when downloading foo.txt twice, foo (1).txt is downloaded at second time). Each :write generates a new file and it would be annoying.

Cool, good job!
