org-ql

This package provides a query language for Org files. It offers two syntax styles: Lisp-like sexps and search engine-like keywords.

It includes three libraries: The org-ql library is flexible and may be used as a backend for other tools. The libraries org-ql-search and helm-org-ql provide interactive search commands and saved views.

Installation

The package may be installed directly from MELPA or with other tools like Quelpa.

After installation, you can use the commands without additional configuration. Note: The command =helm-org-ql= only works if the package =helm-org= is installed; Helm is not a dependency of this package, so it’s not automatically installed.

To use the functions and macros in your own Elisp code, use libraries org-ql and org-ql-view.

Quelpa

Installing with Quelpa is easy:

1. Install quelpa-use-package (which can be installed directly from MELPA).
2. Add this form to your init file:

(use-package org-ql
  :quelpa (org-ql :fetcher github :repo "alphapapa/org-ql"))

Usage

• Commands
• Queries
  • Non-sexp query syntax
  • General predicates
  • Ancestor/descendant predicates
  • Date/time predicates
• Functions / Macros

Feedback on these APIs is welcome. Eventually, after being tested and polished, they will be considered stable.

Lisp code examples are in examples.org.

Commands

• Showing an agenda-like view:
  • org-ql-search (command)
  • org-ql-view (command)
  • org-ql-view-sidebar (command)
  • org-ql-view-recent-items (command)
• Showing a tree in a buffer:
  • org-ql-sparse-tree (command)
• Showing results with Helm:
  • helm-org-ql (command)

org-ql-search

Note: This command supports both sexp queries and non-sexp queries.

Read QUERY and search with org-ql. Interactively, prompt for these variables:

BUFFERS-FILES: A list of buffers and/or files to search. Interactively, may also be:

• buffer: search the current buffer
• all: search all Org buffers
• agenda: search buffers returned by the function org-agenda-files
• An expression which evaluates to a list of files/buffers
• A space-separated list of file or buffer names

GROUPS: An org-super-agenda group set. See variable org-super-agenda-groups.

NARROW: When non-nil, don’t widen buffers before searching. Interactively, with prefix, leave narrowed.

SORT: One or a list of org-ql sorting functions, like date or priority.

Bindings: Keys bound in results buffer.

• r: Refresh results. With prefix, prompt to adjust search parameters.
• v: Show transient view dispatcher (like Magit’s popups).
• C-x C-s: Save query to variable org-ql-views (accessible with command org-ql-view).

Note: The view buffer is currently put in org-agenda-mode, which means that some Org Agenda commands work, such as jumping to entries and changing item priorities (without necessarily updating the view). This feature is experimental and not guaranteed to work correctly with all commands. (It works to the extent it does because the appropriate text properties are placed on each item, imitating an Agenda buffer.)

helm-org-ql

Note: This command uses non-sexp queries.

This command displays matches with Helm. Note: Helm is not a package dependency, so this command only works if the package helm-org is installed.

• Press C-x C-s in the Helm session to save the results to an org-ql-search buffer.

org-ql-view

Choose and display a view stored in org-ql-views.

Bindings: Keys bound in view buffer.

• g, r: Refresh results. With prefix, prompt to adjust search parameters.
• v: Show transient view dispatcher (like Magit’s popups).
• C-x C-s: Save query to variable org-ql-views (accessible with command org-ql-view).

org-ql-view-sidebar

Show a sidebar window listing views stored in org-ql-views for easy access. In the sidebar, press RET or mouse-1 to show the view at point, and press c to customize the view at point.

org-ql-view-recent-items

Show items in FILES from last DAYS days with timestamps of TYPE. TYPE may be ts, ts-active, ts-inactive, clocked, closed, deadline, planning, or scheduled. FILES defaults to those returned by the function org-agenda-files.

org-ql-sparse-tree

Arguments: (query &key keep-previous (buffer (current-buffer)))

Show a sparse tree for QUERY in BUFFER and return number of results. The tree will show the lines where the query matches, and any other context defined in org-show-context-detail, which see.

QUERY is an org-ql query sexp (quoted, since this is a function). BUFFER defaults to the current buffer. When KEEP-PREVIOUS is non-nil (interactively, with prefix), the outline is not reset to the overview state before finding matches, which allows stacking calls to this command. Runs org-occur-hook after making the sparse tree.

Queries

• Non-sexp query syntax
• General predicates
• Ancestor/descendant predicates
• Date/time predicates

An org-ql query is a lisp form which may contain arbitrary lisp forms, as well as certain built-in predicates. It is byte-compiled into a predicate function which is tested with point on each heading in an Org buffer; when it returns non-nil, the heading matches the query.

Notes:

• Bare strings like "string" are automatically converted to (regexp "string") predicates.
• Standard numeric comparator function symbols (<, <=, >, >=, = ) need not be quoted when passed as an argument to predicates which accept them. The resemblance to infix notation is coincidental.

Non-sexp query syntax

The command org-ql-search also accepts, and the command helm-org-ql only accepts, an alternative, non-sexp query syntax. The syntax is simple, and a few examples of queries in both syntaxes should suffice. By default, when multiple predicates are used, they are combined with boolean and.

Sexp syntax	Non-sexp syntax
(todo)	todo:
(todo "SOMEDAY")	todo:SOMEDAY
(todo "SOMEDAY" "WAITING")	todo:SOMEDAY,WAITING
(ts :on today)	ts:on=today
(ts-active :from "2017-01-01" :to "2018-01-01")	ts-active:from=2017-01-01,to=2018-01-01
(clocked :on -1)	clocked:on=-1
(heading "quoted phrase" "word")	heading:"quoted phrase",word
(and (tags "book" "books") (priority "A"))	tags:book,books priority:A
(src :lang "elisp" :regexps ("defun"))	src:defun,lang=elisp or src:lang=elisp,defun
(and (tags "space") (not (regexp "moon")))	tags:space !moon
(priority >= B)	priority:A,B

Note that the priority predicate does not support comparators in the non-sexp syntax, so multiple priorities should be passed instead, as seen in the last example.

General predicates

Arguments are listed next to predicate names, where applicable.

category (&optional categories)

Return non-nil if current heading is in one or more of CATEGORIES (a list of strings).

done

Return non-nil if entry’s TODO keyword is in org-done-keywords.

habit

Return non-nil if entry is a habit.

heading (&rest regexps)

Return non-nil if current entry’s heading matches all REGEXPS (regexp strings).

• Aliases: h.

level (level-or-comparator &optional level)

Return non-nil if current heading’s outline level matches arguments. The following forms are accepted: (level NUMBER): Matches if heading level is NUMBER. (level NUMBER NUMBER): Matches if heading level is equal to or between NUMBERs. (level COMPARATOR NUMBER): Matches if heading level compares to NUMBER with COMPARATOR. COMPARATOR may be <, <=, >, or >=.

link (&optional description-or-target &key description target regexp-p)

Return non-nil if current heading contains a link matching arguments. DESCRIPTION-OR-TARGET is matched against the link’s description and target. Alternatively, one or both of DESCRIPTION and TARGET may be matched separately. Without arguments, return non-nil if any link is found.

outline-path (&rest strings)

Return non-nil if current node’s outline path matches all of STRINGS. Each string may appear as a substring in any part of the node’s outline path. For example, the path Food/Fruits/Grapes would match (olp "Fruit" "Grape").

• Aliases: olp.

outline-path-segment (&rest strings)

Return non-nil if current node’s outline path matches STRINGS. Matches STRINGS as a contiguous segment of the outline path. Each string is compared as a substring. For example the path Food/Fruits/Grapes would match (olps "Fruit" "Grape") but not (olps "Food" "Grape").

• Aliases: olps.

path (&rest regexps)

Return non-nil if current heading’s buffer’s filename path matches any of REGEXPS (regexp strings). Without arguments, return non-nil if buffer is file-backed.

priority (&rest args)

Return non-nil if current heading has a certain priority. ARGS may be either a list of one or more priority letters as strings, or a comparator function symbol followed by a priority letter string. For example: (priority "A") (priority "A" "B") (priority '>= "B") Note that items without a priority cookie never match this predicate (while Org itself considers items without a cookie to have the default priority, which, by default, is equal to priority B).

property (property &optional value)

Return non-nil if current entry has PROPERTY (a string), and optionally VALUE (a string). Note that property inheritance is currently not enabled for this predicate. If you need to test with inheritance, you could use a custom predicate form, like (org-entry-get (point) "PROPERTY" 'inherit).

regexp (&rest regexps)

Return non-nil if current entry matches all of REGEXPS (regexp strings). Matches against entire entry, from beginning of its heading to the next heading.

• Aliases: r.

src (&key lang regexps)

Return non-nil if current entry contains an Org Babel source block. If LANG is non-nil, match blocks of that language. If REGEXPS is non-nil, require that block’s contents match all regexps.

tags (&optional tags)

Return non-nil if current heading has one or more of TAGS (a list of strings). Tests both inherited and local tags.

tags-inherited (&optional tags)

Return non-nil if current heading’s inherited tags include one or more of TAGS (a list of strings). If TAGS is nil, return non-nil if heading has any inherited tags.

• Aliases: inherited-tags, tags-i, itags.

tags-local (&optional tags)

Return non-nil if current heading’s local tags include one or more of TAGS (a list of strings). If TAGS is nil, return non-nil if heading has any local tags.

• Aliases: local-tags, tags-l, ltags.

tags-all (tags)

Return non-nil if current heading includes all of TAGS. Tests both inherited and local tags.

• Aliases: tags&.

todo (&optional keywords)

Return non-nil if current heading is a TODO item. With KEYWORDS, return non-nil if its keyword is one of KEYWORDS (a list of strings). When called without arguments, only matches non-done tasks (i.e. does not match keywords in org-done-keywords).

Ancestor/descendant predicates

ancestors (&optional query)

Return non-nil if current heading has ancestor headings. If QUERY, return non-nil if an ancestor heading matches it. This selector may be nested.

children (&optional query)

Return non-nil if current heading has direct child headings. If QUERY, return non-nil if a child heading matches it. This selector may be nested, e.g. to match grandchild headings.

descendants (&optional query)

Return non-nil if current heading has descendant headings. If QUERY, return non-nil if a descendant heading matches it. This selector may be nested (if you can grok the nesting!).

parent (&optional query)

Return non-nil if current heading has a direct parent heading. If QUERY, return non-nil if the parent heading matches it. This selector may be nested, e.g. to match grandparent headings.

Date/time predicates

All of these predicates take optional keyword arguments :from, :to:, and :on:

• If :from, return non-nil if entry has a timestamp on or after :from.
• If :to, return non-nil if entry has a timestamp on or before :to.
• If :on, return non-nil if entry has a timestamp on date :on.

Argument values should be either a number of days (positive to look forward, or negative to look backward), a ts struct, or a string parseable by parse-time-string (the string may omit the time value).

• Predicates

  ts

  Return non-nil if current entry has a timestamp in given period. If no arguments are specified, return non-nil if entry has any timestamp.

  ts-active, ts-a

  Like ts, but only matches active timestamps.

  ts-inactive, ts-i

  Like ts, but only matches inactive timestamps.

The following predicates, in addition to the keyword arguments, can also take a single argument, a number, which looks backward or forward a number of days. The number can be negative to invert the direction.

• Backward-looking

  clocked

  Return non-nil if current entry was clocked in given period. If no arguments are specified, return non-nil if entry was clocked at any time. Note: Clock entries are expected to be clocked out. Currently clocked entries (i.e. with unclosed timestamp ranges) are ignored.

  closed

  Return non-nil if current entry was closed in given period. If no arguments are specified, return non-nil if entry was closed at any time.

• Forward-looking

  deadline

  Return non-nil if current entry has deadline in given period. If argument is auto, return non-nil if entry has deadline within org-deadline-warning-days. If no arguments are specified, return non-nil if entry has any deadline.

  planning

  Return non-nil if current entry has planning timestamp in given period (i.e. its deadline, scheduled, or closed timestamp). If no arguments are specified, return non-nil if entry is scheduled at any time.

  scheduled

  Return non-nil if current entry is scheduled in given period. If no arguments are specified, return non-nil if entry is scheduled at any time.

Functions / Macros

• Agenda-like views
  • Function: org-ql-block
• Listing / acting-on results
  • Function: org-ql-select
  • Function: org-ql-query
  • Macro: org-ql

Agenda-like views

Function: org-ql-block

For use as a custom agenda block type in org-agenda-custom-commands. For example, you could define a custom series command like this, which would list all priority A items tagged Emacs with to-do keyword SOMEDAY, followed by the standard agenda view, in a single buffer:

(setq org-agenda-custom-commands
      '(("ces" "Custom: Agenda and Emacs SOMEDAY [#A] items"
         ((org-ql-block '(and (todo "SOMEDAY")
                              (tags "Emacs")
                              (priority "A"))
                        ((org-ql-block-header "SOMEDAY :Emacs: High-priority")))
          (agenda)))))

Which would be equivalent to a tags-todo search like this:

(setq org-agenda-custom-commands
      '(("ces" "Custom: Agenda and Emacs SOMEDAY [#A] items"
         ((tags-todo "PRIORITY=\"A\"+Emacs/!SOMEDAY")
          (agenda)))))

However, the org-ql-block version runs in about 1/5th the time.

The variable org-ql-block-header may be bound to a string to use as the block header, otherwise the header is formed automatically.

Listing / acting-on results

Function: org-ql-select

Arguments: (buffers-or-files query &key action narrow sort)

Return items matching QUERY in BUFFERS-OR-FILES.

BUFFERS-OR-FILES is a one or a list of files and/or buffers.

QUERY is an org-ql query sexp (quoted, since this is a function).

ACTION is a function which is called on each matching entry with point at the beginning of its heading. It may be:

• element or nil: Equivalent to org-element-headline-parser.
• element-with-markers: Equivalent to calling org-element-headline-parser, with markers added using org-ql--add-markers. Suitable for formatting with org-ql-agenda--format-element, allowing insertion into an Org Agenda-like buffer.
• A sexp, which will be byte-compiled into a lambda function.
• A function symbol.

If NARROW is non-nil, buffers are not widened (the default is to widen and search the entire buffer).

SORT is either nil, in which case items are not sorted; or one or a list of defined org-ql sorting methods (date, deadline, scheduled, todo, priority, or random); or a user-defined comparator function that accepts two items as arguments and returns nil or non-nil.

Examples:

;; Return list of to-do headings in inbox file with tags and to-do keywords:
(org-ql-select "~/org/inbox.org"
  '(todo)
  :action #'org-get-heading)
;; => ("TODO Practice leaping tall buildings in a single bound  :personal:" ...)

;; Without tags and to-do keywords:
(org-ql-select "~/org/inbox.org"
  '(todo)
  :action '(org-get-heading t t))
;; => ("Practice leaping tall buildings in a single bound" ...)

;; Return WAITING heading elements in agenda files:
(org-ql-select (org-agenda-files)
  '(todo "WAITING")
  :action 'element)
;; => ((headline (:raw-value "Visit the moon" ...) ...) ...)

;; Since `element' is the default for ACTION, it may be omitted:
(org-ql-select (org-agenda-files)
  '(todo "WAITING"))
;; => ((headline (:raw-value "Visit the moon" ...) ...) ...)

Function: org-ql-query

Arguments: (&key (select 'element-with-markers) from where order-by narrow)

Like org-ql-select, but arguments are named more like a SQL query.

• SELECT corresponds to the org-ql-select argument ACTION.
• FROM corresponds to the org-ql-select argument BUFFERS-OR-FILES.
• WHERE corresponds to the org-ql-select argument QUERY.
• ORDER-BY corresponds to the org-ql-select argument SORT, which see.
• NARROW corresponds to the org-ql-select argument NARROW.

Examples:

;; Return list of to-do headings in inbox file with tags and to-do keywords:
(org-ql-query
  :select #'org-get-heading
  :from "~/org/inbox.org"
  :where '(todo))
;; => ("TODO Practice leaping tall buildings in a single bound  :personal:" ...)

;; Without tags and to-do keywords:
(org-ql-query
  :select '(org-get-heading t t)
  :from "~/org/inbox.org"
  :where '(todo))
;; => ("Practice leaping tall buildings in a single bound" ...)

;; Return WAITING heading elements in agenda files:
(org-ql-query
  :select 'element
  :from (org-agenda-files)
  :where '(todo "WAITING"))
;; => ((headline (:raw-value "Visit the moon" ...) ...) ...)

;; Since `element' is the default for SELECT, it may be omitted:
(org-ql-query
  :from (org-agenda-files)
  :where '(todo "WAITING"))
;; => ((headline (:raw-value "Visit the moon" ...) ...) ...)

Macro: org-ql

Arguments: (buffers-or-files query &key sort narrow markers action)

Expands into a call to org-ql-select with the same arguments. For convenience, arguments should be unquoted.

Changelog

Note: Breaking changes may be made before version 1.0, but in the event of major changes, attempts at backward compatibility will be made with obsolescence declarations, translation of arguments, etc. Users who need stability guarantees before 1.0 may choose to use tagged stable releases.

0.5-pre

Added

• View dispatcher using transient.el (like Magit), bound to v in search/view buffers.
• Predicate link, which matches descriptions and targets in Org links.
• Mascot.

Changed

• Binding to refresh search/view buffers changed to r.

0.4.6

Fixed

• Compatibility with newer versions of the peg library, which removed a macro used by this package. (Fixes #75. Thanks to Karl Voit and @karlicoss for reporting.)

0.4.5

Fixed

• Non-case-folding predicates like (todo) unnecessarily disabled case-folding for other predicates. (Issue #114. Thanks to @bitclick for reporting.)

Fixed

• level predicate used with arguments in plain queries. (Thanks to Akira Komamura for reporting.)

0.4

Note: The next release, 0.5, may include changes which will require minor updates to written queries (e.g. a few predicates may be renamed). Users who wish to avoid those changes happening unexpectedly in their configs should avoid upgrading org-ql beyond 0.4 automatically, as they will be pushed to the master branch when ready.

Added

• Commands
  • helm-org-ql-views, which shows one of org-ql-views selected with Helm.
  • org-ql-search can search files in org-directory; customization options are available in the org-ql-search group.
  • org-ql-view-refresh can be called with a prefix argument to adjust search parameters.
• Queries
  • Negation of terms in plain queries using !. For example, tags:space !moon to exclude entries which contain moon.
  • Predicates outline-path (alias olp) and outline-path-segment (alias olps).
  • Predicate src, which matches Org Babel source blocks.
  • Predicates parent and ancestors. (Thanks to Josh Moller-Mara.)

• Respect Org Agenda restriction in org-ql-block. (Thanks to Ihor Radchenko for reporting.)
• Option org-ql-view-sidebar-sort-views.
• Mouseover help-echo text for org-ql-views default view names.
• “Dangling tasks” default view in org-ql-views. (Users who have modified org-ql-views from the default will not see the new view unless they copy it into their config.)

Changed

• Some default org-ql-view views (users who have modified org-ql-views from the default will not see the new views unless they copy them into their config):
  • Rename some views.
  • “Stuck projects” view (now uses descendants instead of children, which is more useful.

Fixed

• Inherit file tags when org-tag-inheritance is enabled. (Fixes #55. Thanks to Mikhail Skorzhinskiy.)
• Call helm-make-source directly instead of using helm-build-sync-source macro. (Fixes #60. Thanks to Matt Huszagh for reporting.)
• Search/view buffers now always end with a newline, which prevents side-scrolling of the window when calling end-of-buffer.
• Face for done to-do keywords in org-ql-view buffers. (Thanks to Yiming Chen.)
• Make view buffers read-only. (Fixes #72. Thanks to xeijin.)
• Sorting with single sorter specified as an atom. (Thanks to Jeff Filipovits.)
• Autoload for org-ql-block agenda block. (Fixes #53. Thanks to reports from Gus Cantieni, Karl Voit, rieje, and Jake | Junxuan.)

Internal

• Added generic node data cache to speed up recursive, tree-based queries.

0.3.2

Fixed

• In org-ql-search, accept symbol as :super-groups argument.
• In the This week and Next week default org-ql-views views, set timestamps for beginning-of-week to 00:00:00 and end-of-week to 23:59:59.
• Plain quoted-phrases in non-sexp queries.

0.3.1

Fixed

• Compatibility with Org 9.2. Thanks to Brian Leung.

0.3

Added

• Alternative, non-sexp query syntax for commands org-ql-search and helm-org-ql. See documentation.
• Command helm-org-ql.
• Command org-ql-sparse-tree, like org-sparse-tree for org-ql queries. (Thanks to Akira Komamura.)
• Command org-ql-view-sidebar.
• Per-buffer, per-heading tag caching, which increases the speed of tags-related queries by 6-7x.
• More tags-related predicates and aliases:
  • For inherited tags: tags-inherited, inherited-tags, tags-i, itags.
  • For heading-local tags: tags-local, local-tags, tags-l, ltags.
  • tags-all, tags&: Matches all given tags using boolean AND (rather than boolean OR, which the tags predicate uses).
• Variable org-ql-block-header, which overrides the default header in org-ql-block agenda blocks.
• Predicate (path).
• Option org-ql-views may now be customized in a guided, structured way with the customization UI (e.g. M-x customize-option RET org-ql-views RET, or press c in the org-ql-view-sidebar buffer).
• Enable more Org Agenda commands in org-ql-view buffers (e.g. setting deadlines and scheduling). (Fixes #35. Thanks to Milan Zamazal and Mikhail Skorzhinskii.)
• Function org-ql-select’s buffers-files argument can be a function which returns a list of buffers and/or files.

Changed

• Predicate heading now accepts multiple regexps, which are matched with boolean AND.
• Predicate regexp now matches its regexp arguments with boolean AND.
• Package org-super-agenda is now a dependency. This removes the need for awkward code to handle the case where it’s not installed, and makes grouping features always available. Of course, the global minor mode org-super-agenda-mode is not activated by org-ql, so no behavior is changed in Org Agenda or org-ql; it only means that commands like org-ql-search will always provide grouping when called with the appropriate arguments.

Removed

• Macro org-ql-agenda. Instead, use function org-ql-search. See also command org-ql-view, etc.

Fixed

• Predicate heading now matches only against heading text, i.e. not including tags at the end of the line, to-do keyword, etc.
• Predicate todo now matches case-sensitively, avoiding non-todo-keyword matches (e.g. a heading which begins Waiting on will no longer match for a todo keyword WAITING).
• Interactive completion in org-ql-search.

Internal

• Refactored code from file org-ql-agenda.el into files org-ql-search.el and org-ql-view.el. Function and variable names have been changed accordingly.

0.2.3

Fixed

• Priority queries could fail to match headings whose to-do keywords had non-alphabetic characters, like TO-READ.

0.2.2

Fixed

• (deadline auto) selector matched entries whose deadlines had a warning period that had not yet been entered (org-deadline-warning-days too soon).

0.2.1

Fixed

• (descendants) selector matched against parent heading instead of only descendants.

0.2

Added

• Function org-ql-query, like org-ql-select but with arguments named more like a SQL query.
• Bare strings like "string" can be used in queries, which are converted to (regexp "string") automatically.
• Selector (regexp) accepts multiple regexps to test.
• Macro org-ql and functions org-ql-query and org-ql-select now also accept a comparator function in their :sort argument.
• Function org-ql-block, which works as an Org Agenda series/composite/block command, usable in custom agenda commands defined in variable org-agenda-custom-commands. (Inspired by Benson Chu’s config.)
• Function org-ql-agenda--agenda optionally takes a list of entries as an argument.
• Selectors ts-a and ts-i, aliases for ts-active and ts-inactive.
• Selector ts now accepts a :type argument.
• Face org-ql-agenda-due-date.
• Selectors (children) and (descendants).
• Function org-ql-search and macro org-ql-agenda accept a :title argument, which is displayed in the header.
• Command org-ql-search offers global org-super-agenda-groups in completion.
• Customization group org-ql.
• Command org-ql-view, which displays views saved to variable org-ql-views, which can be saved from org-ql-search buffers with command org-ql-search-save, which is bound to C-x C-s in view buffers.
• Variable org-ql-view-map, active in view buffers displayed by org-ql-search, org-ql-agenda, and org-ql-view.
• random sort method.
• Save position when refreshing search buffers.

Changed

• Function org-ql-query renamed to org-ql-select. org-ql-query now refers to a new function.
• Macro org-ql no longer accepts a :markers argument. Instead, use argument :action element-with-markers. See function org-ql-select, which org-ql calls.
• Selector (todo) no longer matches “done” keywords when used without arguments (i.e. the ones in variable org-done-keywords).
• Overhauled date/time-based predicates. See documentation for new argument signatures.

Removed

• Selector (date), replaced by (ts).

Fixed

• Handle date ranges in date-based selectors. (Thanks to Cody Goodman, Samuel W. Flint, and Vikas Rawal.)
• Don’t overwrite bindings in org-agenda-mode-map.
• Don’t search buffers without headings, and show a message if the user attempts it.
• Don’t search hidden/special buffers.
• Properly accept arbitrary sort functions in org-ql-select, etc. (Fixes #37. Thanks to Milan Zamazal.)
• Planning-line-related predicates searched too far into entries.
• Add autoloads. (Fixes #36. Thanks to Akira Komamura.)

Compatibility

• Fixes for compatibility with Org 9.2. (Thanks to Ataias Pereira Reis and Daniel Kraus.)

Internal

• Optimizations for some query selectors, e.g. regexp and todo. These can provide a significant improvement for some queries. See benchmarks in notes.org.
• Library ts is now used for parsing and comparing timestamps.

0.1

First tagged release.

Notes

Comparison with Org Agenda searches

Of course, queries like these can already be written with Org Agenda searches, but the syntax can be complex. For example, this query would be difficult to write in a standard Org Agenda search, because it matches against a to-do keyword and a plain-text search. As described in the advanced searching tutorial, it would require using org-search-view with a query with specific regular expression syntax, like this:

+lisp +{^\*+\s-+TO-READ\s-}

But with org-ql-search, you would write a query like lisp todo:TO-READ, or in Lisp syntax, (and "lisp" (todo "TO-READ")).

org-sidebar

This package is used by org-sidebar, which presents a customizable agenda-like view in a sidebar window.
