pi-hashline-edit

Hashline edit extension for pi.

Install

pi install npm:@ravshansbox/pi-hashline-edit

Add -l to install it in project settings.

Usage

It replaces the built-in read and edit tools with hashline versions, modelled on oh-my-pi's hashline edit mode.

read works as before, but text output starts with a [PATH#TAG] header and each line has an N: prefix. TAG is a 4-hex hash of the whole file:

[src/app.py#1A2B]
1:def greet():
2:    print("hi")

edit takes one input string that edits one file:

[src/app.py#1A2B]
PUT 2:
+    print("hello")
PUT >$:
+greet()

Ops:

• PUT N.=M: replaces lines N to M with the + body; no body deletes them. PUT N: replaces one line.
• PUT <N: inserts before line N, PUT >N: after it, PUT >$: at the end.

Line numbers always refer to the file as it was read. edit rejects the patch when its tag no longer matches the file, so the model has to read again instead of editing stale lines. The response gives only the new header, so the model reads again before the next edit.

All ops are checked before the file is written. Line endings and a missing final newline are kept.

edit is shown like the built-in edit tool: the path from the header, then a diff once the edit is done. Unlike the built-in tool, it shows no diff preview before the edit runs.

Differences from oh-my-pi

• No CUT; use PUT with no body.
• No byte order mark handling: it shows as part of line 1.
• No syntax-block ops (PUT N*:).
• No registers (PUT … @name).
• No file ops (REM, MV).
• One file per call.
• No recovery from stale tags using earlier snapshots.
• No check that edited lines were shown by read.
• Tags use a different hash, so they do not match oh-my-pi's.
