Just a tiny post to share a command I use since a quite of time now to grep time ranges, notably the things to do over 7 days.
:grep %sh(p today .. 7 days | cr 'todo.+%F' -j '|')
p is an alias to echo and cr to chronic.
The search output will look something like:
todo.+2020-11-20|todo.+2020-11-21|todo.+2020-11-22|todo.+2020-11-23|todo.+2020-11-24|todo.+2020-11-25|todo.+2020-11-26|todo.+2020-11-27
With the following document, it will match the “today” and “in 7 days” occurrences, but not “yesterday” and “in 14 days”.
TODO 2020-11-19 Something (Yesterday)
...
TODO 2020-11-20 Something (Today)
...
TODO 2020-11-27 Something (in 7 days)
...
TODO 2020-12-04 Something (in 14 days)
If you want something else than days you can configure the range step in days (-d), hours (-h), minutes (-m) and seconds (-s).
You can also do some maths, such as:
p today + 14 days | cr
# 2020-11-27 17:03:05
Which is quite useful if you want to search dates from the prompt.
/%sh(cr -i 'next monday' '%F')<a-!><ret>
Note: <a-!> is to expand typed expansions (here a shell block).
With 2020-12-04 selected:
TODO [2020-12-04] Something (in 14 days)
Searching
/%sh(cr -i "$kak_selection + 7 days" '%F')<a-!><ret>
will jump to 2020-12-11.
In the -i option, you have %s available if you need to map stdin.
Example
p 2020-12-25 | cr -i '%s + tomorrow' '%F'
# 2020-12-26
In Kakoune, you can select dates and map them to other formats.
For example, select:
Oct 8, 2020
Executing
|cr '%F'
will result 2020-10-08.
