[Informational] How to import from jump

[grignaak]

I moved my data from gsamokovarov's jump to zoxide using the following jq command.

The interesting parts are

• It uses a frecency algorithm so the scores can be imported by converting it to the z format first.
• On MacOs/linux the jump database is ~/.jump/scores.json
• Python can output a format that doesn't comply with standard strptime, so the jq script has to fix that by stripping out the microseconds fixing the timezone offset.

This version removes the local timezone offset altogether, using the machine's local offset.

cat >/tmp/jump-import.jq <<'COMMAND'
def pytime:
  sub("\\..*"; "") |
  strptime("%Y-%m-%dT%H:%M:%S")
  ;
map(.Path  + "|"  + (.Score.Weight | tostring)  + "|"  + (.Score.Age | pytime | strftime("%s"))) | .[]
COMMAND
<~/.jump/scores.json | jq -r -f /tmp/jump-import.jq | tee /tmp/jump-db.txt
zoxide import --from z /tmp/jump-db.txt

This definition keeps the local timezone by stripping the colon out of the offset (if you care about exact age AND you move from timezone to timezone):

def pytime:
  sub("(\\.\\d+)?(?<o>[-+](\\d+))(:(?<s>[^:]+))?$"; "\(.o)\(.s)") |
  strptime("%Y-%m-%dT%H:%M:%S%z")
  ;

[Edit] Here is a snippet of my ~/.jump/scores.json to show the structure.

[

      "Weight": 38,

    }
  },
