Zig runs ROM FS Filesystem in the Web Browser (thanks to Apache NuttX RTOS)
ROM FS works like a regular Filesystem (think FAT and EXT4). Just that it’s tiny, runs in memory. And bundles easily with WebAssembly.
ROM FS is a lot simpler than Read-Write Filesystems (like FAT and EXT4). That’s why we run it inside TCC WebAssembly to host our C Header Files.
It’s simpler than FAT and easier to embed in WebAssembly. Probably wiser to split the Immutable Filesystem (ROM FS) and Writeable Filesystem (Tmp FS).

Many Thanks to my GitHub Sponsors (and the awesome NuttX and Zig Communities) for supporting my work! This article wouldn’t have been possible without your support.
Now with Logging Enabled in NuttX ROM FS, we need to handle Complex Format Strings. Thus we extend our formatting to handle Multiple Format Patterns per Format String.
In our NuttX Emulator JavaScript: We read elf_data from the JavaScript Local Storage and pass it to TinyEMU WebAssembly: jslinux.js
