Dataview JS

List all system commands

dv.list(Object.keys(app.commands.commands))

Timecode gymnastics

Contents dv.paragraph(${l2.file.link}) dv.paragraph(${l2.file.link.length}) dv.paragraph(${l2.created}) dv.paragraph(${mom}) $= dv.date('today') + dv.duration('1 week') $= dv.date('today') $= dv.duration('1 week') $= moment(Date.now()) $=dv.luxon.DateTime.now().minus(weeks:4)‘‘$= moment().subtract(14, “days”)` https://forum.obsidian.md/t/how-to-use-constants-and-compare-dates-in-dataviewjs/49073 https://biscotty.online/blogs/dataviewjs-interactive-dynamic-tables https://www.reddit.com/r/ObsidianMD/comments/10n08lr/use_dataview_to_calculate_new_date_by_adding_a/ https://forum.obsidian.md/t/dataviewjs-filtering-query-using-dates/72733

Search by tag and relative dates, return property

$= dv.pages("#application").where(t => t.Created && moment(t.Created).format('yyyy-MM-DD HH:mm') > moment(Date.now()).subtract(3, "months").format('yyyy-MM-DD HH:mm')).file.frontmatter["Role Title"]

Return all info on a file

disabled via “ because this page has so much data on it from all the calls $= dv.span(dv.current())

Search by tag, relative date, and group by specific property

let l1 = dv.pages("#Application and #industry").where(t => t.Created && moment(t.Created).format('yyyy-MM-DD HH:mm') > cutoff)
let l2 = l1.groupBy(t => t.tags.filter(x => x.includes("industry")))```

Dataview DQL

Group and count files by time interval, with ctime limit

TABLE length(rows) as Count 
FROM #application 
WHERE (file.ctime >= (date(today) - dur(12 week)))
SORT file.ctime DESC
GROUP BY dateformat(file.ctime, "DD") as day

Return list of tags

make sure you DO NOT include a target variable next to List. Apparently it will get added on its own when you declare as

LIST
FROM #Application 
FLATTEN file.tags as tag
GROUP BY tag
WHERE icontains(tag, "#industry")

Search by certain tag, but omit other tags in results

TABLE WITHOUT ID file.link as Company, filter(file.etags, (x) => contains(x, "industry")) as
Industry, Checked as Last_Checked
FROM #newcompany and #industry/Materials   
SORT Checked ASC

Search by other (text, binary) metadata

The ‘sport_type’ variable is a text field. To search for empy binarys use WHERE !complete

TABLE WITHOUT ID file.link as Link, distance as Dist
FROM Strava WHERE sport_type = “Run” :> ```

Mapview

old embedded map

{“name”:“Default”,“mapZoom”:5,“centerLat”:38.7837304,“centerLng”:-100.445882,“query”:“tag:#Application ”,“chosenMapSource”:0,“autoFit”:false,“lock”:false,“showLinks”:false,“linkColor”:“red”,“markerLabels”:“off”,“embeddedHeight”:650}

Templater

Note that the <% %> delimiters for Templater code break the callout block, so they have been omitted for visual clarity

Add frontmatter

Method 1: Declare together, anywhere in template ⇒ { app.fileManager.processFrontMatter(tp.config.target_file, frontmatter ⇒ { frontmatter['Tags'] = [("company/" + companyname), ('Interviews')] }) }, 200)

companyname = await tp.system.prompt(“Enter the company name”) setTimeout(()

Method 2: Declare individually, in template header

<%* let company_name = await tp.system.prompt("Enter the company name") _%> 
<% "---" %>
Created: <% tp.date.now("YYYY-MM-DD") %>
Tags: <% [("company/" + company_name), 'Interviews'] %>
<% "---" %>

Replace characters general variables

Let title = “{{title | replace(’:’, ”) | replace(’#’, ”) | replace(’^’, ”) | replace(’|’, ”) | replace(’[’, ”) | replace(’]’, ”) | replace(’\’, ”) | replace(’/’, ”)}}“;
