@brief Creates a dataset with the output from `GIT_STATUS()`
|
|
@details Uses `git_status()` to fetch the number of changed files, then
|
|
iterates through with `git_status_get()` and `git_index_add()` for each
|
|
change - which is created in an output dataset.
|
|
|
|
Usage:
|
|
|
|
%let dir=%sysfunc(pathname(work))/core;
|
|
%let repo=https://github.com/sasjs/core;
|
|
%put source clone rc=%sysfunc(GITFN_CLONE(&repo,&dir));
|
|
%mf_writefile(&dir/somefile.txt,l1=some content)
|
|
%mf_deletefile(&dir/package.json)
|
|
|
|
%mp_gitstatus(&dir,outds=work.gitstatus)
|
|
|
|
