Add Emscripten filesystem images to an R package repository

Source: R/lib.R
make_vfs_repo.Rd

Creates an Emscripten filesystem image for each R package that exists in the package repository directory repo_dir.

Usage

make_vfs_repo(repo_dir = "./repo", compress = FALSE)

Arguments

repo_dir

The package repository directory. Defaults to "./repo".

compress

When TRUE, add and compress Emscripten virtual filesystem metadata in the resulting R package binary .tgz files. Otherwise, file_packager() is used to create uncompressed virtual filesystem images included in the output binary package repository. Defaults to TRUE.

Details

Each filesystem image is generated using Emscripten's file_packager() tool and the output .data and .js.metadata filesystem image files are written to the repository in the same directory as the package binary .tgz files.

The resulting filesystem images may then be used by webR to download and install R packages by mounting the .data images to the Emscripten virtual filesystem.

When compress is TRUE, an additional file with extension ".data.gz" is also output containing a compressed version of the filesystem data.
