`--cat`, `--tag` and `--category_name` are WP_Query arguments that already
worked here and nothing wrote down. Checked with values shaped the way the
command line delivers them, since none of this needs code to work:
cat=2 -> 1 post
cat=2,3 -> 2 posts, comma matches any
cat=-2 -> 2 posts, a negative ID excludes
tag=alpha-tag -> 1 post
tag=alpha-tag,beta-tag -> 2 posts, comma matches any
tag=alpha-tag+beta-tag -> 0 posts, plus requires all
'feed' is left alone deliberately. It is a query var WordPress fills in for
RSS and the like, it filters nothing when passed to WP_Query, and writing it
down would advertise a no-op.
'tag_id' is left alone for a different reason. It filters, but documenting a
name puts it in the candidate set wp-cli/wp-cli#6392 matches typos against,
and 'tag_id' sits within two edits of both 'page_id' and 'tag__in'. It would
trade the two false positives this commit removes for two others.

Sweeping the rest of WP_Query's query vars turned up more that work here and nothing writes down. Each was tried with a value shaped the way the command line delivers it, and only the ones that changed the result are documented: - meta_key and meta_value, which is how you filter on a custom field - hour, minute and second, which finish the date family that already had year, monthnum, day, m and w - has_password and post_password - orderby and order Left alone for cause: 'sentence', 'perm', 'preview', 'error', 'tb', 'paged', 'embed' and 'sticky' change nothing when passed, and 'page_id' filters but sits within two edits of 'paged' and 'tag_id', so documenting it would add two false positives to wp-cli/wp-cli#6392 the way 'tag_id' would. All three of hour, minute and second together is deliberately not asserted. That path compares a DATE_FORMAT() string rather than separate HOUR() and MINUTE() clauses, and the SQLite integration plugin does not emulate it the way MySQL does: the same query matches on MariaDB and matches nothing on SQLite. Two units at a time behaves the same on both and is covered. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014SSZzqMJRDTiLiDxQEPYcL

Guessing at which arguments are worth writing down produced two that should
not have been: 'has_password' and 'post_password' filter, but neither is a
WP_Query argument. They are not in the docblock on WP_Query::parse_query,
which is the list WP_Query actually documents, and they are gone again.
Working from that docblock instead turned up the reverse problem, a lot of
arguments left out for no reason. The list ones - post__in, author__in,
category__in, tag__in and their relatives - were skipped on the belief that
a comma-separated value would reach WP_Query as a string and quietly match
its first entry alone. That was wrong: process_csv_arguments_to_arrays()
already splits every argument whose name contains '__'. They work:
wp post list --post__in=4,5 --format=count -> 2
wp post list --post_name__in=one,two -> 2 posts
date_query, meta_query and tax_query were likewise already handled - list_()
names all three for JSON decoding - and likewise undocumented.
Sixty-three arguments are documented now, every one of them in the
parse_query docblock. What is left out of that docblock is either internal
bookkeeping, where a CLI user has no reason to reach ('cache_results',
'no_found_rows', 'suppress_filters', the cache-priming flags), or means
something other than it appears to for a list ('page' paginates within a
single post, 'comments_per_page' and 'posts_per_archive_page' are not about
this query).
Documenting a family by halves turned out to be worse than documenting all
of it, measured against the near-match check in wp-cli/wp-cli#6392:
documented set false positives
before this commit 2
+ the list arguments only 3 'tag_id' now looks like 'tag__in'
+ those and the id arguments 3 'paged' now looks like 'page_id'
+ those and pagination 2
everything here 2
Each partial step stranded a name whose neighbours had just been documented.
The two that survive are 'feed' and 'tb', which are not filters at all.

The parse_query docblock records when arguments arrived, and four of the ones
documented here arrived after the oldest WordPress this command is tested
against:
title, post_name__in 4.4.0
comment_count 4.9.0
search_columns 6.2.0
Only 'search_columns' lands past the floor, and its scenario was failing on
4.9 for that reason: the argument is not recognised there, so '--s' searches
every column and the narrowing the scenario asserts does not happen. It is
its own scenario now, tagged @require-wp-6.2, rather than sitting inside a
scenario that has to run everywhere.
The two 4.4 arguments get @require-wp-4.4 on the scenarios that exercise
them, which changes nothing on a current install but matches how the rest of
this suite guards itself.

WordPress 4.9 is the floor here, so saying that 'title' and 'post_name__in' need 4.4 tells a reader nothing they can act on, and 'comment_count' arrived in 4.9 itself. Those three notes are gone, along with the @require-wp-4.4 tags that came with them - the one already on the meta keys scenario is older than this branch and stays. 'search_columns' is the only one past the floor, so it keeps its note and its @require-wp-6.2 scenario.

Make the multi-column search assertion discriminating.
This assertion expects the same count as the default search at Lines 858-862. It passes if search_columns=post_title,post_content is ignored or is not converted into separate columns. Add a post with zebra only in post_excerpt. Then assert that the default search returns three posts and the two-column search returns two posts.

Do not require --meta_key for --meta_value.
WP_Query supports a value-only meta clause. WP_Meta_Query::parse_query_vars() creates a clause when meta_value is present without a meta key. Replace “Needs --meta_key” with wording that says --meta_key restricts the value filter to one key. (developer.wordpress.org)

Follows #643. Started from @ekamran's note in wp-cli/wp-cli#6392 that
--catand--tagare undocumented, then took the argument list from the docblock onWP_Query::parse_query()— 75 entries — and documented the ones that make sense here.Documentation only, no code. 63 options are documented now, every one of them in that docblock.
What was missing, and why
The list arguments —
post__in,author__in,category__in,tag__inand relatives — were the largest gap, and I had earlier claimed they needed code before they could be documented, on the belief that a comma-separated value would reachWP_Queryas a string and quietly match its first entry alone. That was wrong.CommandWithDBObject::process_csv_arguments_to_arrays()already splits every argument whose name contains__:date_query,meta_queryandtax_querywere the same story from the other direction:list_()names all three for JSON decoding, and nothing documented them.Everything documented here was run through the command with values shaped the way the shell delivers them, not assumed. Two behaviours worth writing down came out of that:
--offsetdoes nothing until--posts_per_pageis bounded, because the command defaults it to-1.--page_id,--pagenameand--attachment_idneed a matching--post_typeto return anything.What is left out of the 75, and why
Not a
WP_Queryargument at all.has_passwordandpost_passwordwere in an earlier revision of this PR. Both filter, so they looked right, but neither appears in theparse_querydocblock. Removed.Internal bookkeeping, where a CLI user has no reason to reach:
cache_results,no_found_rows,suppress_filters,update_post_meta_cache,update_post_term_cache,update_menu_item_cache,lazy_load_term_meta.Means something other than it appears to for a list:
pagepaginates within a single post, andcomments_per_page/posts_per_archive_pageare not about this query.Not filters at all — passing them changes nothing, so documenting them would advertise a no-op:
feed,tb,preview,error,embed,sticky.--feedcame up directly in #6392; it is the query var WordPress fills in when routing an RSS request.Documenting a family by halves is worse than documenting all of it
Measured against the near-match check in wp-cli/wp-cli#6392, over the whole query-var list:
maintoday--tag→--day,--cat→--day,--feed→--field,--tb→--ptag_idnow looks liketag__inpagednow looks likepage_id--feed→--field,--tb→--pEvery intermediate false positive was an artifact of documenting half a family and stranding a name whose neighbours had just become candidates. The two that survive are the two query vars that are not filters, which is the irreducible floor here.
A backend difference worth knowing
--hour,--minuteand--secondwork individually and in pairs. All three at once does not work under SQLite: for more than two unitsWP_Date_Query::build_time_query()compares aDATE_FORMAT()string instead of separateHOUR()/MINUTE()/SECOND()clauses, and the SQLite integration plugin does not emulate that identically.Not caused by this PR and not fixable here. The scenario asserts two units at a time, which behaves the same on both, with a comment saying why.
