Recfiles Extended Example


Requirements


Create

Make a database for your boardgames, specifying only one field and value:

1database=games.rec
2n=Name
3g=Vojvodina
4touch ${database}
5recins -f ${n} --value ${g} ${database}
6recsel ${database}

Insert a few more, with the estimated playtime:

1recins -f Name -v Saboter -f Playtime -v 30 ${database}
2recins -f Name -v Chess -f Playtime -v 30 ${database}

View all games, or select one by number:

1recsel ${database}
2recsel -n 0 ${database}

Each game should note whether or not you have played it yet, so you can add that field and set the default to yes.

1f=played
2v=yes
3recset -f ${f} -a ${v} ${database}

...but the field is wrong, it should have a capital letter:

1new_field=Played
2recset -f ${f} --rename ${new_field}

Read

Check how many records the database has:

1recinf ${database}

Look at just the games you've never played:

1recsel --expression="Played = 'no'" ${database}

Print how many, then just print the names:

1recsel -e "Played = 'no'" --count ${database}
2recsel -e "Played = 'no'" --print=Name ${database}

Update

To change a game's Played field from no to yes, use recset to specify the number, and change that field.

1num=0
2f=Played
3value=yes
4recsel --number=${num} ${database}
5recset --number=${num} -f ${f} --set=${value} ${database}

Find all games with a playtime of 30, and set the field Max_Players to 4.

1recset -e "Playtime = 40" -f Max_Players --set 50 games.rec

This doesn't work, because that field does not exist. You can --set-add the field, to add it wherever it does not exist.

1recset -e "Playtime = 40" -f Max_Players --set-add 50 games.rec

Delete

Remove Played record from first game:

1num=0
2recset --number=${num} -f Played --delete ${database}

You can comment the line instead of deleting it:

1num=1
2recset --number=${num} -f Played --delete ${database}
3recsel ${database}
4cat ${database}

Delete an entire record:

1num=2
2recdel --number=${num} ${database}
