Hi,
I authored the days filter operator. Haven’t been here for a while, and came back to find several threads all revolving around more or less the same thing - an inability to produce a range of days that ends yesterday (past days) or starts tomorrow (days in the future). I submitted a patch #2364 <https://github.com/Jermolene/TiddlyWiki5/pull/2364> to address the issue. Following is a description of the days filter operator, most of it is applicable now, but cases involving a start day of tomorrow or an end day of yesterday will only be possible after the patch. Parameter The parameter (let’s call it D) is a number of days from today. It marks a begining or an end of a time interval. 0 is today only. 1 is tomorrow and everything before, -1 is yesterday and everything after, etc. Suffix 3 days in the future may not make sense for a field like “modified”. That’s where the suffix comes in handy. Say you have a field “due” in your tiddlers. days:due[3] will return tiddlers that are due within 3 days from today, and all past due. Negation (logical NOT) This is where the patch will change the behavior a bit. If days:due[3] is everything that is due within the next 3 days, then, strictly speaking, !days:due[3] should mean anything that is NOT due due within the next 3 days, or , in other words, anything that is due in 4 days or more. That’s how the operator works now, and that makes it impossible to specify a period starting tomorrow or ending yesterday, since !days:due[1] means “due in 2 days or more”, and !days:due[-1] means “was due 2 days ago or before”. After the patch, !days:due[1] will mean anything that is due in *1* days or more, !days:due[-1] will mean anything that was due yesterday or before. Specifying a range of days (finite number of days) Everything we’ve looked at so far was open-ended intervals. To get a closed interval, you simply combine two days operator steps in a filter run <http://tiddlywiki.com/#Filter%20Run>, and sometimes add a third one in a filter expression <http://tiddlywiki.com/#Filter%20Expression> Examples (after the patch) today: <<list-links '[days:due[]]'>> 4 days ago: <<list-links '[days:due[-4]!days:due[-4]]'>> <<list-links '[days:due[-4]] -[days:due[-3]]'>> last 5 days: <<list-links '[days:due[-5]!days:due[-1]sort[due]]'>> next 5 days: <<list-links '[!days:due[1]days:due[5]sort[due]]'>> day before yesterday: <<list-links '[days:due[-2]] -[days:due[-1]]'>> yesterday: <<list-links '[days:due[-1]] -[days:due[]] -[!days:due[1]]'>> <<list-links '[days:due[-1]!days:due[-1]]'>> tomorrow: <<list-links '[!days:due[1]days:due[1]]'>> <<list-links '[!days:due[1]] -[!days:due[2]]'>> day after tomorrow: <<list-links '[!days:due[2]] -[!days:due[3]]'>> On Saturday, March 12, 2016 at 7:54:25 AM UTC-8, Julian Kniephoff wrote: Sorry for the late reply, I was trying to figure out the best way to share > this, but I didn't have that much time on my hands, so I'm just going to > attach the js files; you should still be able to just drag and drop them > into your TiddlyWiki. > > To answer your questions: > > - The two filters take the field they are operating on as their > operand.
