Function for constructing relative paths in R? -

-

is there similar make.path.relative(base.path, target.path)?

i want convert full paths relative paths given base path (like project's directory).

similar, shorter:

make.path.relative = function(base, target) {   common = sub('^([^|]*)[^|]*(?:\\|\\1[^|]*)$', '^\\1/?', paste0(base, '|', target))    paste0(gsub('[^/]+/?', '../', sub(common, '', base)),          sub(common, '', target)) }  make.path.relative('c:/home/adam', 'c:/home/adam/tmp/r') #[1] "tmp/r"  make.path.relative('/home/adam/tmp', '/home/adam/documents/r') #[1] "../documents/r"  make.path.relative('/home/adam/documents/r/project', '/home/adam/minetest') #[1] "../../../minetest"

voodoo regex comes from here.

asp.net mvc - breakpoint on javascript in CSHTML? -

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
