Implement --shortstat option for git_log function

[i2z1]

Implement option to show additions and deletions in commit as we can perform with

git log --shortstat

So with gert it can be done with something like

gert::git_log(repo = ".", shortstat = TRUE)

Maybe you can create something yourself from looking up the diff/patch for each commit

df <- gert::git_log(max=10)
df$shortstat <- lapply(df$commit, function(id){
  patch <- gert::git_diff_patch(id)
  # do something with stats
})

Yes, it is working walkaround for problem, but is there libgit2 limitations? This walkaround recipe needs further parsing for diff output. Or is it package architecture decision?

[jeroen]

We could probably do it using libgit2, but it adds more overhead. What do you need this for?

I have added a new function git_commit_stats for you: https://github.com/r-lib/gert/commit/d4b28083f07eecebda3a395a4c582c93d5caa663. You can install the new version from https://ropensci.r-universe.dev/gert

So you can do e.g.:

library(gert)
logs <- git_log(max=10)
stats <- lapply(logs$commit, git_commit_stats)

Thanks a lot!!! I am trying to analyze commits, who are just fixing typos in comments and who are writing code but maybe without any comments etc...

One more question -- is it possible to get all commits from all branches like git log --all with gert::git_log() function?

No not yet, we just recursively walk to the parent commits right now, without considering branches. It's been on the todo list to implement something better but I haven't gotten to it.
