Michael GrundbergandClaude Opus 5 f9edb33d15 fix(terminal): trim the padding and shared indent out of a copied selection
xterm hands back whole screen rows and trims only the cells that were
never written to, so the real spaces a full-screen TUI paints across the
unused part of a row count as content and reach the clipboard. Measured
against Claude Code in a 282-column pane, single lines arrived carrying
138 trailing spaces, and every line carried the two-space transcript
indent as well. Windows Terminal, iTerm2 and GNOME Terminal all trim that
for you, decideAutoCopy already calls a wall of spaces "never what the
gesture meant", and _selectTouchSelectionLine already treats those cells
as padding — the mouse and keyboard paths never had the same rule.

CodemanCopySelection.clean lives in constants.js beside decideAutoCopy,
its pure sibling. It drops the trailing run from each line, and removes
the leading run only where every selected row shares one. A selection of
a single row keeps its run, because one row shares nothing with anything
and stripping it would silently reindent one line of `git log` body text
or one line out of `less`. A drag that began inside a row keeps its
partial first line untouched and out of the measurement, which otherwise
pins the shared run to zero and leaves every following row indented.

Every pass over a line is a scan rather than a regex. `/[ \t]+(\r?)$/` is
quadratic on a line whose spaces are followed by a non-space character,
which is what right-aligned or centred TUI content looks like: measured
over 50 000 rows with a 280-column run it took 2.9s, against 1.3ms for
the scan, and a 2 000-column run took 16s. The scan is also the faster of
the two on an ordinary padded row.

cleanedTerminalSelection in terminal-ui.js is the half that needs the
live terminal. It returns a COLUMN selection untouched: Alt+drag makes
one, and a rectangle's rows lining up is the point of the gesture, so
both halves of the clean would destroy it. xterm exposes the mode nowhere
public, so the check reads terminal._core._selectionService, the way this
file already reads terminal._core for cell dimensions, and cleans
normally if a future xterm renames the field. A test pins that assumption
against the library rather than against a stub repeating the literal.

The Ctrl+C chord decides on the cleaned selection, not the raw one. A
drag across the blank part of a row selects real padding spaces, so the
raw text is truthy, and testing it would spend that press on a copy of
nothing and make the user press again to interrupt. A padding-only
selection is now dropped and the press falls through to the PTY, while
Ctrl+Shift+C still never falls through. copyTerminalSelection gates on
trim() for the same reason, since a multi-row drag across padding cleans
to line breaks alone and a bare newline pasted into a chat composer
submits it.

All four of the main terminal's copy paths go through it: the Ctrl+C
chord, right-click, the phone selection button and Auto Copy. The
browser's own Edit menu copy, a disabled copy shortcut and the subagent
windows still copy raw rows, as they did before, and the invariants doc
now says so rather than claiming every copy is cleaned. Auto Copy
resolves its own toggle before it reads the selection, since it is off by
default and a selection can run to the 50 000-row scrollback ceiling.

Changesets

Hello and welcome! This folder has been automatically generated by @changesets/cli, a build tool that works with multi-package repos, or single-package repos to help you version and publish your code. You can find the full documentation for it in the repository.

What is a changeset?

A changeset is a piece of information about changes made in a branch or commit. It holds three bits of information:

  • What packages need to be released
  • What semver bump type each package should receive (major / minor / patch)
  • A summary of the changes

How do I create a changeset?

Run npx changeset or create a .md file in this directory with the following format:

---
"codeman": patch
---

Description of changes

The frontmatter specifies which package(s) to bump and the bump type. The body is the changelog entry.
