Check File Status

Check if a particular file has had local changes that have not been commited yet.

Use the git status command, with short -s option:

• modified: the grepl(’ M ’) check will be true
• new: the grepl(‘??’) check will be true
• existing no change: the (st_git_status == ““) check will be true

spg_modified <-
  paste0('git status -s',
         'C:/Users/fan/R4Econ/amto/array/fs_ary_mesh.Rmd')
spg_anewfile <-
  paste0('git status -s',
         'C:/Users/fan/R4Econ/math/differentiation/fs_differentiate_lhopital.Rmd')
spg_nochange <-
  paste0('git status -s',
         'C:/Users/fan/R4Econ/math/func_ineq/fs_atkinson_ces.Rmd')

st_git_status <- toString(system(spg_modified, intern=TRUE))
