Agenda built-in or customized commands are statically defined. Agenda
|
||||
filters and limits provide two ways of dynamically narrowing down the
|
||||
list of agenda entries: /filters/ and /limits/. Filters only act on
|
||||
the display of the items, while limits take effect before the list of
|
||||
agenda entries is built. Filters are more often used interactively,
|
||||
while limits are mostly useful when defined as local variables within
|
||||
custom agenda commands.
|
||||
filters and limits provide two ways of narrowing down the list of
|
||||
agenda entries.
|
||||
|
||||
Filters only change the visibility of items, are very fast and are
|
||||
mostly used interactively[fn:96]. You can switch quickly between
|
||||
different filters without having to recreate the agenda. If creating
|
||||
the agenda seems slow, one solution would be to create a view that
|
||||
contains everything you might want to work on for a while, and then
|
||||
use filtering to drill down.
|
||||
|
||||
Limits on the other hand take effect before the agenda buffer is
|
||||
populated, so they are mostly useful when defined as local variables
|
||||
within custom agenda commands.

The general filtering command that gives access to the full

Filter the agenda view with respect to a tag and/or effort
|
||||
estimates. The difference between this and a custom agenda command
|
||||
is that filtering is very fast, so that you can switch quickly
|
||||
between different filters without having to recreate the
|
||||
agenda.[fn:96]
|
||||
Filter the agenda view with respect to a tag. You are prompted for
|
||||
a tag selection letter; {{{kbd(SPC)}}} means any tag at all.
|
||||
Pressing {{{kbd(TAB)}}} at that prompt offers completion to select a
|
||||
tag, including any tags that do not have a selection character. The
|
||||
command then hides all entries that do not contain or inherit this
|
||||
tag. Call the command repeatedly to add several tags to the
|
||||
filter. When called with prefix argument, remove the entries that
|
||||
/do/ have the tag. Pressing {{{kbd(+)}}} or {{{kbd(-)}}} at the
|
||||
prompt also switches between filtering for and against the next tag.
|
||||
{{{kbd(\)}}} at the prompt turns off the filter and shows any hidden
|
||||
entries.

#+vindex: org-agenda-auto-exclude-function
|
||||
Org also supports automatic, context-aware tag filtering. If the
|
||||
variable ~org-agenda-auto-exclude-function~ is set to a user-defined
|
||||
function, that function can decide which tags should be excluded
|
||||
from the agenda automatically. Once this is set, the {{{kbd(/)}}}
|
||||
command then accepts {{{kbd(RET)}}} as a sub-option key and runs the
|
||||
auto exclusion logic. For example, let's say you use a =Net= tag to
|
||||
identify tasks which need network access, an =Errand= tag for
|
||||
errands in town, and a =Call= tag for making phone calls. You could
|
||||
auto-exclude these tags based on the availability of the Internet,
|
||||
and outside of business hours, with something like this:
|
||||
|
||||
