+# Streamer mode's words
+
+The words streamer mode hides (Settings > Network Setup > Streamer Mode; the
+`streamer.*` settings in `port/linux/README.md`). The game builds them in
+from `port/linux/game/text_filter_terms.inc`, which
+`tools/text_filter_terms.py` writes from Surge AI's list and these files:
+
+| File | Contents |
+| --- | --- |
+| `review.txt` | The review of every base word of Surge AI's list: kept (its group, severity and where it may be found) or dropped, and the spellings dropped. The words are ROT13'd. |
+| `allow.txt` | Words never hidden, however a hidden word sits inside them (Scunthorpe), in plain text |
+| `english.txt` | The words of the English word list (`port/third_party/english-words`) that the list hides, ROT13'd, which `tools/test_text_filter_terms.py` checks |
+
+`python3 tools/text_filter_terms.py --list` shows the table decoded, and
+`--check "some text"` shows what the game would hide in a text.
+
+## Surge AI's list
+
+The words, their categories and their severities come from Surge AI's
+profanity list, "The Obscenity List": 1,598 English profanities and their
+spellings, each with up to three base words, up to three categories and a
+severity that five raters gave it (Mild, Strong or Severe).
+
+Upstream: https://github.com/surge-ai/profanity (gone since; the Internet
+Archive's copy of its page of 1 March 2025 shows an MIT `LICENSE`, whose text
+it did not keep), copied at https://huggingface.co/datasets/mmathys/profanity
+(MIT), revision `c2a17bf3ec64d9b6418ead1cb5f7ef26dbdffccb`: `profanity_en.csv`,
+SHA-256 ca4ff7d713a8e6f6ec2616f489cd09f6fb96b8b3af404a207783be58a91f3ede.
+
+The CSV is not in the repository: give `tools/text_filter_terms.py --surge`
+its path to write the table again (and `HALO_SURGE_CSV` its path for the
+test that checks it).
+
+The groups are made from its categories (`tools/text_filter_terms.py`'s
+`GROUPS`), each base word in one, then reviewed (`review.txt`):
+
+| Group | Surge AI's categories |
+| --- | --- |
+| SLURS | racial / ethnic slurs, sexual orientation / gender, mental disability, physical disability, political |
+| SWEARING | sexual anatomy / sexual acts, bodily fluids / excrement, religious offense |
+| INSULTS | other / general insult, animal references, physical attributes |
+
+The review adds words of the project's own that their list has not (`term`
+lines at its end): sexual words (porn, hentai and the like), words for
+sexualised minors, hate phrases and harassment ("kill yourself"), each with a
+severity the default levels hide (slurs from mild, swearing from strong).
+
+The table is made from their list, so it carries their notice:

 votes drop both kinds as unknown, so the network version is unchanged.

+The text chat (`network_chat.c`): a client sends its player's line to the
+host (`_distributed_message_chat_up`, reliably), which takes it only from
+the client's own stream and from one of that machine's players, at most 5
+lines at once and one each 1.5 seconds after (more are dropped; a machine
+gone from the game has its count let go, so one new to its slot starts
+afresh), its text cut to 63 characters of printable ASCII but `|` (which
+the game's text drawing takes for the start of a code; it becomes `?`, on
+the host and again on each client). The host alone sends the line on
+(`_distributed_message_chat_down`, reliably, with the sender's absolute
+index and its channel, the line's flags): to every client, a team's line
+only to the machines with a player of the sender's team (to every one in a
+game without teams), and a vehicle's line only to those with a player
+riding in the sender's vehicle (the outermost object each unit is a child
+of, so any map's vehicles), as the host has them; the sender's machine gets
+its own line whatever it is. The host shows it itself if one of its own
+players hears it or said it. A client shows only
+the host's lines, its own too, so every machine shows them in one order,
+and takes them (and the chat settings below) only over the host's
+connection's stream: a datagram from the host's address could be anyone's.
+Each local player's view shows the lines that player hears.
+The host's own `/mute <player> [minutes]` and `/unmute <player>` are
+commands, not lines: it keeps a mute by the player's name (in ASCII,
+matched in either case, as the host keeps names apart) and its minutes by
+its own clock, drops the lines of a muted player's machine
+when they come up, and sends that machine alone a notice of the minutes
+left; it tells every machine of each mute and unmute. A notice is a down
+line with `_chat_line_notice_bit` set, its text alone (no sender). A
+client's `/mute` is never sent, and the host takes the text of a line that
+came up as a line, never a command. The host's scoreboard Mute for everyone
+is the same mute (20 minutes), and the host relays none of a muted player's
+machine's voice either (`network_voice.c`'s `voice_host_relay`, by the
+names of the network game's players, which the lobby has too). A
+machine's own scoreboard mute stays its own: it plays none of that
+machine's voice and shows none of its players' lines, and tells no one.
+The host's chat settings (`network.text_chat`: on, links allowed, or off;
+always off while its game is listed in the server browser,
+`p2p_hosting_listed`) go to every client in
+`_distributed_message_chat_config` (one byte of flags), reliably, as they
+change and every 3 seconds. A client without them (from a host without the
+chat, or before they come) has the chat off, and so does a client in a
+public game it joined from the server browser, whatever its host sends (a
+changed host could turn the chat on): while the tunnel reaches the host of
+the listing it joined (`p2p_join_listing`, `p2p_joined_listed_host`; any
+other invite joined since forgets it), it takes no chat line or notice and
+sends none. A client refuses a line the
+settings refuse before sending it, and the host refuses it again whatever
+the client knew, telling its machine why: a changed build gets no further.
+Links are found in the line's text (`chat_text_has_link`): a scheme, `www.`,
+an address of four numbers, or a name and a common top-level domain, its
+dots also written `(dot)`, `[dot]`, `{dot}`, `(.)`, `[.]` or ` dot `, with
+spaces about them or not, or a dot with spaces both sides; a domain that is
+a word as well (`me`, `to`, `is`) counts only with a path, a port or another
+domain after it (`chat_link_domain`).
+Builds without the chat drop the three kinds as unknown, so the network
+version is unchanged.

+### Text chat
+
+Network games have a text chat, as the PC version had. Press T
+(`controls.chat`) to type a line to all the players, or Y
+(`controls.team_chat`) to type one to your team (in a game without teams,
+to all the players). While you type, Tab changes who the line is to, in
+turn: all the players, your team, or your vehicle (the players riding in
+the vehicle you ride in, whatever the map's vehicles are, Custom Edition
+maps' too; on foot, only you see it). Enter sends the line, Escape cancels
+it. While you type, your player does not move.
+
+With a controller, D-pad Up opens an on-screen keyboard at the bottom right
+(on Android, at the bottom in the middle) for a line to all the players:
+the left stick (or D-pad Left and Right) moves between the keys, A types
+the key, X deletes, Y switches capitals, D-pad Up and Down change who the
+line is to (all the players, your team, your vehicle), Start sends the
+line, and B closes the keyboard (the button that closed it does nothing in
+the game until you let it go). Its last row has Aa (capitals), #+= (the
+symbols), space, DEL and SEND. On a touchscreen (Android, and a browser on
+a phone or tablet), the touch controls' D-pad Up opens it, a tap on a key
+types it, and a tap anywhere else closes it: the touch controls hide while
+it is up. While the keyboard is up the controller and the touch controls
+move nothing in the game. The face buttons are the same places on
+other controllers (on a PlayStation controller: Cross types, Square
+deletes, Triangle switches capitals, Circle closes).
+
+The lines show above the motion sensor, in a column a little over half the
+screen wide: a long line wraps onto the next rows, and the line you type
+shows its end when it is wider. The player's name is in the colour of
+their team (blue in a game without teams), the text in a pale blue, and the
+host's notices in a pale gold; WHITE in CHAT TEXT in Settings > Network
+Setup > Multiplayer HUD (`display.chat_style`) draws them all white, as
+Custom Edition does. A line to the
+team says "(team)" after the name, one to the vehicle "(vehicle)". The
+lines go after ten seconds; while you type, the last six rows show. Where
+the touch controls are (Android, and a browser whose touch controls you
+use), the lines go at the top left, the newest highest. In split screen,
+each player's view shows the lines that player hears, and the first player
+types. No line shows, and none can be typed, in a menu, in a cinematic or
+while the HUD is hidden; opening a menu ends the line being typed. A new
+game starts with no lines. A line has 63 characters at most, letters,
+numbers and punctuation but `|` only (ASCII; `|` becomes `?`). `debug.txt`
+gets every line.
+
+Streamer mode (refer to "Streamer mode") hides offensive words in the
+chat's lines and players' names as it does in all the text the game draws:
+only on your screen, never in what is sent, and never in the line you are
+typing.
+
+The host sends each line on: a player of an older build does not see the
+lines and cannot send them. The host takes 5 lines at once from a machine,
+then one each 1.5 seconds; a machine that joins starts afresh.
+
+TEXT CHAT in Settings > Network Setup > Multiplayer HUD (`display.text_chat`)
+can HIDE the chat entirely, for purists and streamers: no lines show, and
+its keys open nothing.

+Setup > Teamplay Options (in co-op, Voice and Voting; `network.text_chat`):
+ON (the default: a line with a link, such as `discord.gg/...`,
+`example.com`, `www.`, an address, or `example [dot] com`, is refused),
+WITH LINKS, or OFF. A domain that is a word as well (`.me`, `.to`, `.is`)
+counts only with a path after it (`youtu.be/...`), so that `go.to` and
+`he.is` are not refused. A game listed in
+the server browser (a public internet game) never has the text chat,
+whatever it says (TEXT CHAT shows OFF there, and cannot be changed, while
+LISTING is PUBLIC); a private game, joined by its invite, and a LAN game have
+it as chosen. A player who joins a game from the server browser has no text
+chat in it even if its host turns it on: their game takes no line from that
+host and sends none. Pressing T where the chat is off says so, and a refused line
+tells its sender why.
+
+On the scoreboard (right-click, then click the player), Mute voice and chat
+mutes a player for you alone: you no longer see their lines or hear their
+voice, and nobody else is told. The host's scoreboard also has Mute for
+everyone: no machine sees the player's lines or hears their voice for 20
+minutes, or until the host picks Unmute for everyone, and all the players
+see "Milenko muted for 20 minutes". The mute holds in the lobby too. A
+machine's voice is one: muting one of two players in split screen mutes
+the other's voice too.
+
+The host can also mute a player from the chat: type `/mute <player>
+<minutes>`, as `/mute Milenko 5` (20 minutes when you give none, 1440 at
+most), which mutes their voice too. The player is found as the console's `kick` finds one: the whole
+name in either case, else the one player whose name begins with what you
+typed. All the players see "Milenko muted for 5 minutes". The muted
+player's lines go to no one, and they see how many minutes are left. The
+mute ends when its minutes are up, or with `/unmute <player>`. A player
+who leaves and joins again under the same name, in either case, is still
+muted. Only the

+changes only what this machine shows: the names others see, and what the
+machines send each other, stay as they are.
+
+The words come from Surge AI's rated list of English profanities, reviewed
+for the game (`port/assets/text_filter`), in three groups, each with a level
+that hides that severity and worse:
+
+| Group | Setting | Default | What it has |
+| --- | --- | --- | --- |
+| SLURS | `streamer.slurs` | `"mild"` (all) | Slurs about race, ethnicity, nationality, religion, sexuality, gender and disability |
+| SWEARING | `streamer.swearing` | `"strong"` | Swearing and sexual words; the mildest (damn, hell) show at `"strong"` |
+| INSULTS | `streamer.insults` | `"off"` | Name-calling that is not a slur |
+
+A word is found however it is dressed: in capitals or with accents, in
+look-alike letters (Cyrillic, Greek, full-width, small capitals), in leet
+(`0` for o, `@` for a, `ph` for f), with its letters stretched ("fuuuck"),
+with punctuation between them (`f.u.c.k`), spaced out (`f u c k`, `fu ck`),
+and with characters the game does not draw (zero-width spaces, the menus'
+`|` codes) between them. Each word may be found inside a name, at a word's
+start, or only as a whole word, as fits it, and some words are never
+hidden though a hidden one is inside them (Scunthorpe). `python3
+tools/text_filter_terms.py --check "some text"` shows what would be hidden.
+
+What it cannot catch: letters added into a word or its letters scrambled, new
+spellings, a word split between two names or two lines, voice chat (mute a
+player from the scoreboard, or set `audio.voice_volume` to 0), and pictures.

+drawn each frame is looked at once.

+TEXT_FILTER_MATCH.C
+
+Streamer mode's matcher: which code units of a string spell a hidden word,
+however it is dressed (README.md, "Streamer mode"). A string is read as the
+game draws it (draw_string.c's parsers: a wide string's "|n" breaks a line
+and any other "|" hides the character after it; a narrow string's style
+codes are not drawn), and each character it shows becomes an element:
+
+- a letter, of a-z: the case folded, accents and look-alikes (Cyrillic,
+  Greek, full-width, small capitals: text_filter_fold.inc) made plain;
+- a digit or symbol read as letters (leet: 0 o, 1 i or l, 3 e, @ a, $ s...),
+  or as any letter (* # % ?, the last of which is what the server browser's
+  listings show for a character they cannot), which may also be
+  punctuation;
+- a space or punctuation, which a word may be spelled across;
+- anything else, which no word crosses.
+
+Two elements together may read as one letter (ph f, vv w, \/ v, |< k).
+Then each term (text_filter_terms.inc, made by tools/text_filter_terms.py
+from Surge AI's list; and the player's own) is looked for from each element:
+a run of one letter reads as one ("fuuuck"); punctuation may come between
+letters ("f.u.c.k"); spaces too where the pieces are a letter or two
+("f u c k", "fu ck") or the match is whole words ("f uck"). A term's rule
+says where it may be (inside a word, at a word's start, or as the whole
+word), and the allowed words (Scunthorpe) are never hidden. Nothing here
+knows the game: the harness builds it alone (tools/harness).

+The game's wasm, most of a build, does not come from GitHub Pages, which

+checks that jsDelivr serves that commit's file

+fetches the wasm from there as it caches the build, checks its SHA-256, and
+takes the site's copy only when that fails; the page loads `halo.wasm` from
+the site as before, from the worker's cache. jsDelivr serves files of at most
+20 MB from GitHub: a larger wasm comes from the site, and the step says so.

+
+The list (port/assets/text_filter/README.md): Surge AI's profanity_en.csv
+(MIT), each row a spelling with up to three base words, three categories
+and a severity (Mild, Strong, Severe). A base word's group is its own row's
+first category's (failing that, the first category most of its spellings
+give): SLURS, SWEARING or INSULTS (GROUPS). Its severity is the worst of the
+rows that name it alone (failing that, of all its rows). Its spellings are
+the rows that name it alone, kept to their letters; those with digits or
+symbols are left to the matcher's leet, and those another term already
+finds are left out.
+
+port/assets/text_filter/review.txt is the review of every base word, the
+words ROT13'd (nothing in the repository spells them out):
+
+    keep <group|-> <severity|-> <rule|-> <word> a base word kept: its group
+                                                (- Surge's first category's),
+                                                its severity (- Surge's),
+                                                its rule (- worked out)
+    drop <word>                                 a base word or spelling left out
+    term <group> <severity> <rule|-> <word>     a word of the project's, or
+                                                a spelling's own settings
+
+A rule (where a term may be found: text_filter.h) worked out is "anywhere"
+when no English word (tools/../port/third_party/english-words) has it but
+its own forms (s, es, ed, er, ing, y), "start" when none starts with it but
+those, and "whole" otherwise. port/assets/text_filter/allow.txt is the words
+never hidden (Scunthorpe), in plain text.
+
+A base word of the CSV that the review does not name stops the generator,
+which then prints a line to review for each (--template prints them all).
+The CSV is not in the repository: the .inc records its checksum, and
+tools/test_text_filter_terms.py checks the .inc against the review without
+it. --fold writes text_filter_fold.inc, the characters above ASCII that read
+as letters, from Python's Unicode names (its version is recorded).
