A Binary Download Manager.

binman

Tools and functions for managing the download of binary files. Binary repositories are defined in YAML format. Defining new pre-download, download and post-download templates allow additional repositories to be added.

Installation

You can install binman from GitHub with:

# install.packages("remotes")
remotes::install_github("ropensci/binman")

Usage Examples

GitHub Assets

The following is an example of using binman to get the GitHub assets from a project. The project is https://github.com/lightbody/browsermob-proxy/releases . When a new version is released a zipped binary is added as an "asset". A JSON representation of the project releases is available at https://api.github.com/repos/lightbody/browsermob-proxy/releases. binman needs a YAML file to specify how to parse this projects assets:

name: binman-bmproxy
predlfunction:
  "binman::predl_github_assets":
    url: https://api.github.com/repos/lightbody/browsermob-proxy/releases
    platform:
    - generic
    history: 3
    appname: "binman_bmproxy"
    platformregex: browsermob-proxy
dlfunction:
  "binman::download_files": []
postdlfunction:
  "binman::unziptar_dlfiles": []

The file can be accessed at:

ymlfile <- system.file("examples", "yaml", "bmproxy.yml", package = "binman")

Downloading the three most recent releases can the be done using:

process_yaml(ymlfile)

with resulting directory structure (We omit files for brevity):
