Parsing Git Log
Let's parse git log
This git log command is interesting but you can't do a lot with it like this.
git logLet's make it more parsable
git log --pretty="%h|%s|%aN|%aE|%aD" -n 25This will work but I've been burnt by this in the past when a pipe | gets injected in the commits.
So, let's try again with something that most likely won't show up in commits, »¦«. Also, since we're not using a pipe now we don't have to use quotes around the pretty format string. Notice that the output is just a bunch of strings.

First we need to get it in lines or rows. Notice that the output is now in a table format.

───┴─────────────────────────────────────────────────────────────────────────────────────────────────That's more like nushell, but it would be nice to have some columns.
We used the delimiter »¦« specifically so we can create columns so let's use it like this.

───┴──────────┴──────────────────────┴──────────────────┴────────────────────────┴──────────────────Yay, for columns! But wait, it would really be nice if those columns had something other than generically named column names.
Let's try adding the columns names to split column like this.
git log --pretty=%h»¦«%s»¦«%aN»¦«%aE»¦«%aD -n 5 | lines | split column "»¦«" commit subject name email dateAhhh, that looks much better.

───┴──────────┴──────────────────────┴──────────────────┴────────────────────────┴──────────────────Hmmm, that date string is a string. If it were a date vs a string it could be used for sorting by date. The way we do that is we have to convert the datetime to a real datetime and update the column. Try this.
git log --pretty=%h»¦«%s»¦«%aN»¦«%aE»¦«%aD -n 5 | lines | split column "»¦«" commit subject name email date | upsert date {|d| $d.date | into datetime}Now this looks more nu-ish

───┴──────────┴──────────────────────────┴──────────────────┴────────────────────────────┴──────────────If we want to revert back to a date string we can do something like this with the nth command and the get command.

Now that we have a real datetime we can do some interesting things with it like group-by or sort-by or where. Let's try sort-by first
git log --pretty=%h»¦«%s»¦«%aN»¦«%aE»¦«%aD -n 25 | lines | split column "»¦«" commit subject name email date | upsert date {|d| $d.date | into datetime} | sort-by date────┬──────────┬──────────────────────────┬───────────────────┬───────────────────────────┬──────────────

────┴──────────┴──────────────────────────┴───────────────────┴───────────────────────────┴──────────────Now, with the 365 day slice of data, let's group-by name where the commits are less than a year old. This table has a lot of columns so it's unreadable. However, if we group-by name and transpose the table things will look much cleaner. Pivot takes rows and turns them into columns or turns columns into rows.

...Side note: If you happen to get errors, pay attention to the error message. For instance, this error means that the data being returned from git log is somehow incomplete. Specifically, there is a missing date column. I've seen git commands work perfectly on Windows and not work at all on Linux or Mac. I'm not sure why. If you run into this issue, one easy way to temporarily avoid it is to limit git log results to a certain number like git log -n 100.

│ There isn't a column named 'date'
│ Perhaps you meant 'commit'? Columns available: commit, subjectHere's one tip for dealing with this error. We have a do command that has an --ignore_errors parameter. This is how you'd use it in the above example, if it were giving errors.
git log --pretty=%h»¦«%s»¦«%aN»¦«%aE»¦«%aD | lines | do -i { split column "»¦«" commit subject name email date } | upsert date {|d| $d.date | into datetime} | where ($it.date > ((date now) - 365day)) | group-by name | transposeNow, back to parsing. What if we throw in the sort-by and reverse commands for good measure? Also, while we're in there, let's get rid of the [table 21 rows] thing too. We do that by using the length command on each row of column1.
git log --pretty=%h»¦«%s»¦«%aN»¦«%aE»¦«%aD | lines | split column "»¦«" commit subject name email date | upsert date {|d| $d.date | into datetime} | where ($it.date > ((date now) - 365day)) | group-by name | transpose | upsert column1 {|c| $c.column1 | length} | sort-by column1 | reverse─────┬─────────────────────────────────┬─────────

...This is still a lot of data so let's just look at the top 10 and use the rename command to name the columns. We could've also provided the column names with the transpose command.

───┴────────────────────┴─────────And there you have it. The top 10 committers and we learned a little bit of parsing along the way.
Here's one last little known command. Perhaps you don't want your table numbered starting with 0. Here's a way to change that with the table command.
