Shell, editor and terminal configuration, and the tools that go with them https://git.soarez.net/sz/dot.git/atom?h=master 2026-09-25T10:49:05+00:00 2026-09-25T10:49:05+00:00 Igor Soarez igor@soarez.org 2026-09-25T10:49:05+00:00 urn:sha1:b0714511e8557686cda9e0551324fd273a97e9b1 `exit` was a function that ran `tmux detach` instead of exiting, whenever a shell was interactive and inside tmux. What it bought was a keystroke: tmux already binds detach to prefix-d, which this config does not touch. What it cost was an afternoon. Claude Code captures shell functions into a snapshot and sources it in every tool call, so agent shells inheriting $TMUX ran the function too: terminal windows closed on their own for weeks before anyone connected it to `exit`, and a poll loop that called `exit 0` detached a client every minute instead of stopping, because the function detached and then returned. The call-time guard added on 2026-07-16 fixed that case; it did not make shadowing a POSIX builtin a good idea. Nothing in either repo calls it and nothing documents the behaviour. 2026-09-17T18:45:23+00:00 Igor Soarez igor@soarez.org 2026-09-17T18:45:23+00:00 urn:sha1:13cc065ec014b86369dfe4ad60d1a43fa06fd251 Shell, editor and terminal configuration, the tools that go with them, and szecret, an age-based secret manager whose store lives elsewhere. History restarts here. What came before was not written to be read by anyone else, and carried machine names, addresses and an encrypted secret store; it is kept privately instead. What is left is meant to be safe on any machine, including one whose owner is not me: see CLAUDE.md for the rule it is written to.
