Check the modification time of an input file continously in an infinite loop. Whenever the time indicates the file has been modified, call a function to recompile the input file.
knit_watch(input, compile = knit, interval = 1, ...)an input file path (or a character vector of mutiple paths of input files)
a time interval to pause in each cycle of the infinite loop
other arguments to be passed to the compile function
This is actually a general function not necessarily restricted to
applications in knitr. You may specify any compile function to
process the input file. To stop the infinite loop, press the
Escape key or Ctrl + C (depending on your editing environment
and operating system).
# NOT RUN {
# knit_watch('foo.Rnw', knit2pdf)
# knit_watch('foo.Rmd', rmarkdown::render)
# }
