I don't think the FS was designed for that purpose. But I'm not sure if there is a reason stopping it from working that way. You would need to somehow grab the FS object from one module and make it accessible to the other, so they share one FS (probably need some new Emscripten options for that). If you did that, things might work - at least I can't think of a reason for them not to ;)
Another option is to write glue code, as you said, to manually move around data between two FSes. A third possible route is to use BrowserFS ( https://github.com/jvilk/BrowserFS ). It can plug into Emscripten filesystems, and I'm not sure but I think might be able to handle multiple external sources. - Alon On Thu, Apr 23, 2015 at 1:48 AM, Łukasz Adamczak <[email protected]> wrote: > I'm looking to implement a web application which combines 2 Emscripten > modules. > > Think an IDE with a text editor, an Assembler (module 1) and an Emulator > (module 2). > https://dl.dropboxusercontent.com/u/118061/neside/neside-flow.png > > The general flow I'm hoping to achieve: > > 1.
