file.lists | yes groupIn:no |
1.To groupBy page.file.link as G1 (G1=group.rows) 2.To flatten page.file.lists 3.To gather a list item(or a task item) under any heading 4.To gather a list item(or a task item) that contains a highlighted text 5.To gather a highlighted text and push it into the aMatch array 6.To display each highlighted text in each single line |
The DVJS10 is based on the DVJS90 in the following topic. - Solutions: by Justdoitcc |
Notes
Summary
Q1: The same codes
Summary_Q1
- To filter the data by page.file.ctime
Original Example10
- To compare the dates
```JS
// M11. define pages: gather all relevant pages
// #####################################################################
let pages = dv
.pages('"100_Project/01_dataviewjs/01_by_example/Q21_Highlight/Q21_test_data"')
.where(
(page) =>
page.file.ctime >= dv.date("1984-03-01T00:00:00") &&
page.file.ctime <= dv.date("1984-05-31T23:59:59")
);
```
Another Example11
- To compare the strings of the dates
```JS
// M11. define pages: gather all relevant pages
// #####################################################################
let pages = dv
.pages('"100_Project/01_dataviewjs/01_by_example/Q21_Highlight/Q21_test_data"')
.where(
(page) =>
page.file.ctime.toFormat("yyyy-MM-dd HH:mm:ss") >=
dv.date("1984-03-01T00:00:00").toFormat("yyyy-MM-dd HH:mm:ss") &&
page.file.ctime.toFormat("yyyy-MM-dd HH:mm:ss") <=
dv.date("1984-05-31T23:59:59").toFormat("yyyy-MM-dd HH:mm:ss")
);
```
Q2: What does the following Regular Expression mean?(M31)
Summary_Q2
```JS
// M31.FR10 define REGEX_HIGHLIGHTED_TEXT:
// The pattern matches highlighted texts like `==text==` instead of `== text==`
// Capturing Group (x) : Matches x and remembers the match.
// Non-Capturing Group (?:x) : Matches "x" but does not remember the match.
// Quantifier *? : Matches the previous token between
// zero and unlimited times, as few times as possible,
// expanding as needed (lazy)
// Modifier g : global. All matches (don't return after first match)
// Modifier u : unicode. Enable all unicode features and
// interpret all unicode escape sequences as such
// #####################################################################
// Capturing Group (x) + non-greedy y*?
// const REGEX_HIGHLIGHTED_TEXT = /(==[^\s].*?==)/gu;
// Non-Capturing Group (?:x) + non-greedy y*? : (For better performance)
const REGEX_HIGHLIGHTED_TEXT = /(?:==[^\s].*?==)/gu;
```
A2:
Non-Capturing Group (?:x) + non-greedy y*?
- Non-Capturing Group
(?:==[^\s].*?==) - Global pattern flags
- g modifier: global. All matches (don’t return after first match)
- u modifier: unicode. Enable all unicode features and interpret all unicode escape sequences as such

Q3: How to get the file.path of the note named dic_19850301?
Summary_Q3
A3:
using Inline DQL
```SQL
full_file_path = `=[[dic_19850301]].file.path`
```
//=>100_Project/01_dataviewjs/01_by_example/Q84_Contains/Q84_test_data/03/dic_19850301.md
From the result, you can copy the path as needs.
using Inline DVJS
```JS
full_file_path = `$=dv.page("dic_19850301").file.path`
```
//=>100_Project/01_dataviewjs/01_by_example/Q84_Contains/Q84_test_data/03/dic_19850301.md
From the result, you can copy the path as needs.
