+# 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 table is made from their list, so it carries their notice:

+#
+# Dropped: everyday words the list has because they can be offensive in some
+# uses (the filter has no context), and words for identities or anatomy that
+# are neither slurs nor swearing. Moved: gendered insults filed under
+# "sexual orientation / gender" go to SWEARING, homophobic phrases filed under
+# the sexual categories go to SLURS, and the mild insults filed under "mental
+# disability" or "sexual orientation / gender" go to INSULTS. Severities
+# raised or lowered where one spelling's rating set the word's (damn and butt
+# are mild, as Ofcom rates them; the Australian slur rated mild is strong).

+## Streamer mode

+Streamer mode (Settings > Network Setup > Streamer Mode, `streamer.enabled`)
+hides offensive words as stars wherever the game draws text that other
+people or files wrote: players' names over their heads, in the kill feed, on
+the scoreboards and in the lobbies, the server browser's games, the host's
+notices in the console, map and mod names, and the text of a map's or mod's
+own string lists, as well as the message boxes about mods and maps. It
+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.
+What you type is shown as you type it.
+
+Your own words: `text_filter.txt` in the data root, with lines of `add
+<word>` (hidden whenever streamer mode is on) and `allow <word>` (never
+hidden), read when the game starts and when the settings change. The web
+build's page draws its own list of mods, which is not filtered.

+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).

+A list of 370,105 English words, by dwyl and its contributors, released into
+the public domain (the Unlicense, see `LICENSE.md`).
+
+Upstream: https://github.com/dwyl/english-words, commit
+`20f5cc9b3f0ccc8ce45d814c532b7c2031bba31c`. `words_alpha.txt.gz` is its
+`words_alpha.txt` (SHA-256
+3ed0c94610d8bcf7c11bbb49c56aa49c7234d32b66824df91f554169e572da48), unchanged
+but compressed (`gzip -9 -n`).
+
+Nothing the game builds uses it. Streamer mode's tools do:
+`tools/text_filter_terms.py` works out where each word it hides may be found
+(inside a word, at a word's start, or only as a whole word) from which
+English words contain it, and `tools/test_text_filter_terms.py` checks that
+the words hidden in English are those expected
+(`port/assets/text_filter/english.txt`).

+"""Streamer mode's words (port/linux/game/text_filter_match.c): writes
+port/linux/game/text_filter_terms.inc from Surge AI's rated list of
+profanities and this project's review of it, and lists or tries them.
+
+    python3 tools/text_filter_terms.py --surge .../profanity_en.csv
+    python3 tools/text_filter_terms.py --list [slurs|swearing|insults]
+    python3 tools/text_filter_terms.py --check "some text"
+    python3 tools/text_filter_terms.py --fold
+
+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).
