问题描述
我有兴趣向我编写的名为Slidify的R包提供命令行界面.它使用Rscript，我认为这将使其跨平台.脚本存储在子目录inst/slidify中.为了从任何目录使用脚本，我将其路径添加到了.bash_profile上，就像在Mac上一样.
I am interested in providing a command line interface to an R package called Slidify that I am authoring. It uses Rscript and I think that would make it cross-platform. The scripts are stored in the subdirectory inst/slidify. In order to use the script from any directory, I added its path to my .bash_profile as I am on a Mac.
我的问题是
- 我应该如何以自动化的跨平台方式处理脚本的安装?
- 如何确保在此过程中保留文件权限?
-
脚本的shebang行应该是什么?我目前正在使用
- How should I handle installation of the script in an automated cross-platform way?
- How can I make sure that the file permissions are retained in this process?
What should the shebang line for the script be? I am currently using
#!/usr/bin/Rscript --vanilla --slave
我将对如何处理此问题的指针以及已经完成的R软件包的任何示例表示赞赏.为了确保这一点，我很清楚，用户只需在命令行中运行slidify generate slides.Rmd，便可以从slides.Rmd生成幻灯片.
I would appreciate pointers on how to handle this and any examples of R packages that already do it. Just to make sure, I am clear on how this would work, a user would be able to generate a slide deck from slides.Rmd by just running slidify generate slides.Rmd from the command line.
更新:
这是我从命令行在Mac上安装它的方式.我通过37个信号使用了出色的 sub 库来创建脚本.
Here is how I install it on a Mac from the command line. I use the excellent sub library by 37 signals to create the scripts.
echo "$(path/to/clidir/slidify init -)" >> ~/.bash_profileexec bash
echo "$(path/to/clidir/slidify init -)" >> ~/.bash_profileexec bash
两个后续问题
- 我可以将这些命令打包到R函数
install_slidify_cli中吗? - 如何为Windows用户镜像这些命令?
- Can I package these commands into an R function
install_slidify_cli? - How can I mirror these commands for Windows users?
推荐答案
爱'slidify，所以很乐意提供帮助.
Lovin' slidify so would be glad to help.
但是总之，你不能.
R软件包根本无法安装在$R_HOME或所选库文件夹之外.将脚本运送到包装中，并告诉用户复制它.如果有更好的方法，请在 littler 包中加上前身/替代Rscript长期使用它，并且roxygen/roxygen2也会发货.
R packages simply cannot install outside of $R_HOME or the chosen library folder. Ship the script in the package, and tell users to copy it. If there was a better way, out littler package with predecessor / alternative to Rscript would long have used it, and roxygen / roxygen2 would also have shipped something.
