oh-my-pi/packages/hashline/src/prompt.md

Line-anchored patch language: name original lines/gaps to replace, insert, cut, or paste; then give new content. : headers take + body rows; colonless paste PUT, CUT, REM, MV take none.

Section: `[PATH#TAG]`; `TAG`: 4-hex snapshot from latest `read`/`search`, REQUIRED each section. New files: `write`; hashline edits existing files only. Only after a seen-line rejection supplies a retry token: verify its revealed lines, then use exactly `RETRY TOKEN` to apply the stored unchanged patch without resending it. A retry is one-shot and revalidates live files. If intent changes, submit a revised full patch instead. NEVER invent or reuse tokens. `PUT N.=M:`: replace original inclusive lines N–M with body. `PUT N*:`: replace syntactic block beginning N; closing line resolved. `PUT N:` insert body rows after line N (`PUT >$:` = file tail). `PUT >N*:`: insert after block N's end, at sibling depth. Append inside block: `PUT >M:`. `PUT N @name` paste register `@name` at the gap before/after line N; omit `@name` for the anonymous register. `PUT N.=M @name` / `PUT N* @name` paste `@name` over the range / resolved block; `@name` required here. `CUT N.=M` / `CUT N*`: delete and capture inclusive lines N–M / block N; anonymous or given `@name`. `REM`: delete section file. `MV DEST`: move/rename (quote paths with spaces); prior edits apply to source, final content to `DEST`. Single line: `PUT N.=N:` / `CUT N.=N`. Ranges name original inclusive touched lines; body length irrelevant. Only below `:` headers. Row: verbatim `+TEXT` (leading whitespace preserved); `+`: blank. NEVER `-old`, bare, or context rows: range deletes; body is final content. Keep line: exclude it from every range. Literal initial `-`/`+`: `- item` → `+- item`; `+ item` → `++ item`. - Numbers and `#TAG`: latest `read`/`search` `LINE:TEXT`; numbers are original, never shifted by hunks. - Each edit renumbers and changes `#TAG` → next numbers from edit response or fresh `read`. - Touch displayed lines only; undisplayed hunks REJECTED. Far from read window: re-`read`; confirm construct. - Elisions UNSEEN: `…`, `..`, collapsed `N-M:` rows. NEVER hunk in/across one; `read` first. - NEVER start/end range mid-expression or mid-block. - Ranges: changed lines only; NEVER widen over keepers. Non-adjacent changes: separate hunks. - Whole construct: `PUT N*:`; internal lines: `PUT N.=M:`. - `PUT N*:` resolves exactly node N. Leading decorators/attributes/doc-comments are separate nodes: point N at first decorator to include both. Standalone line-comments never swept: use `PUT N.=M:`. - Block ops: opening line of multi-line construct, NEVER closer, last line, bare inner statement. One statement: plain `PUT N.=N:` / `CUT N.=N` / `PUT >N:`. At closer: `PUT >M:`. - Markdown headings are block openers. Block op on `##`/`###`: whole section through deeper headings to next same/higher heading. After section `PUT >N*:`: end body with blank line to separate next heading. - Pure addition: `PUT N:`, NEVER widened `PUT N.=M:`. - Move: `CUT`+`PUT`; `CUT 5.=9 @fn` → `@fn`, `PUT >40 @fn` pastes. Single call-local move: unlabeled `CUT` + `PUT >40`. Named registers persist across edit calls. - NEVER format/restyle with this tool; run project formatter. `read` output shape: ``` [greet.py#A1B2] 1:def greet(name): 2: msg = "Hello, " + name 3: print(msg) 4:greet("world") ```

Edit, then move:

[greet.py#A1B2]
PUT 1.=3:
+def greet(name):
+    print(f"Hi, {name}")
MV lib/greet.py

Markdown bullets — file receives - task:

[PLAN.md#A1B2]
PUT >2:
+- task
+  - nested task

Move greet to sibling file via named register; flows across sections:

[greet.py#A1B2]
CUT 1* @fn
[other.py#3C4D]
PUT <1 @fn

PUT 1*: resolves lines 1–3 (def through print(msg)); line 4 separate, remains:

[greet.py#A1B2]
PUT 1*:
+def greet(name):
+    print(f"Hello, {name}")

Decorator/doc-comment separate block: point N at decorator to include both; anchoring def line 2 orphans @cache:

[svc.py#C3D4]
PUT 1*:
+@cache
+def load(key):
+    return store[key]

# WRONG — empty `PUT` to delete. RIGHT: `CUT 4.=4` PUT 4.=4:

WRONG — range sized to the post-edit content. RIGHT: PUT 1.=1: (body length irrelevant)

PUT 1.=2: +def greet(name):

WRONG — - rows / bare context lines do not exist; the range deletes, the body is only new content.

PUT 3.=3: msg = "Hello, " + name

• print(msg)

• return msg

RIGHT

PUT 3.=3:

• return msg

WRONG — pure insertion as a widened PUT: retyped keepers get dropped (here line 4).

PUT 2.=4:

• msg = "Hello, " + name
• extra = compute(name)
• print(msg)

RIGHT — touch nothing you keep.

PUT >2:

• extra = compute(name)

WRONG — PUT >N*: anchored on the closing delimiter / last visible line. RIGHT: plain PUT >M:

PUT >3*: +after()

RIGHT

PUT >3: +after()

WRONG — body rows under register PUT; register pastes take no body. RIGHT: bodyless PUT >20 @fn.

PUT >20 @fn: +function f() {}

1. RE-GROUND AFTER EVERY EDIT: edits renumber and change `#TAG`; take next numbers from edit response or fresh `read`. Stale tag/surprise: STOP; re-`read`. 2. RANGES TIGHT: changed lines only. Whole construct: `PUT N*:`. 3. BODY FINAL CONTENT: every row starts `+`; Markdown bullet: `+- item`, not `- item`.
