watch a directory for changes to .Rmd (knitr+markdown files) and if any change, knit them. Best used with Marked by Brett Terpstra (set it to watch the .md files that knitr will generate).
| # watch all .Rmd files in a directory, if any change, knit them | |
| library(knitr) | |
| # use watch from Hadley's testthat package | |
| library(testthat) | |
| watchr<-function(path){ | |
| # the path supplied here can just be something like "./" | |
| # taken from auto-test.r | |
| knit_it<-function(added, deleted, modified) { | |
| changed <- normalizePath(c(added, modified)) | |
| for(a_file in changed){ | |
| knit(a_file) | |
| } | |
| TRUE | |
| } | |
| watch(path,knit_it,".Rmd") | |
| } |
