Add flag similar to --short but filter the entry body for the search term

[DanaKirsh]

Use Case/Motivation

On days out I often write a long list of things I've done as one entry, somewhere in the middle the entry might include @movie or @show tags with the movie or show I went to see. I often like to filter my journal for all the movies or shows I've seen, but using --short only includes the title of the entry e.g. "day in town" rather than "Beetlejuice @movie"

Example Usage

If my journal is

[24-05-2023 10:00] New York day 12
Got a train to Penn station
Visited central synagogue
Empire state building
Harry potter and the cursed child Broadway @show in the Lyric Theatre (won ticket lottery)

[11-01-2024 09:00] Prague day 4
11:00 tour of the Clementinum 
Visited the Jewish cemetery
Went to see Carmen @opera @show at the Prague State Opera

[06-10-2024 13:13] London day out
Walked around the shops
The Comedy of Errors @show at Shakespeare's Globe
Lunch at Pizza place @eat-out

Running jrnl --contains @show --short currently produces:

[24-05-2023 10:00] New York day 12

[11-01-2024 09:00] Prague day 4

[06-10-2024 13:13] London day out

I'd like a command that produces jrnl --contains @show --relevant-short:

[24-05-2023 10:00] Harry potter and the cursed child Broadway @show in the Lyric Theatre (won ticket lottery)

[11-01-2024 09:00] Went to see Carmen @opera @show at the Prague State Opera

[06-10-2024 13:13] The Comedy of Errors @show at Shakespeare's Globe

It might be worth considering an option that inputs both the title and the relevant line in the entry jrnl --contains @show --compact:

[24-05-2023 10:00] New York day 12
Harry potter and the cursed child Broadway @show in the Lyric Theatre (won ticket lottery)

[11-01-2024 09:00] Prague day 4
Went to see Carmen @opera @show at the Prague State Opera

[06-10-2024 13:13] London day out
The Comedy of Errors @show at Shakespeare's Globe
