From 469e95c2573e938c0963ba52e8d06dd6aa7ba262 Mon Sep 17 00:00:00 2001 From: Tian Yuchen Date: Tue, 14 Jul 2026 11:25:18 +0800 Subject: [PATCH] environment: move editor_program into repo_config_values The global variable 'editor_program' holds the path to the user's preferred editor. Move 'editor_program' into 'struct repo_config_values' to continue the libification effort. There have been discussions on whether external programs like editors truly need to be configured on a per-repository basis within the same process. While a single process might rarely invoke different editors, this migration is necessary for two reasons: 1. Developers frequently use different toolchains for different projects. Per-repo configuration respects this. 2. Moving this string into 'repo_config_values' eliminates mutable global state. As the codebase moves toward becoming a long-running processes, managing multiple repositories concurrently must not overwrite each other's program configurations. No standalone getter function is introduced. Callers directly access the field via 'repo_config_values()'. Heap memory is safely reclaimed in 'repo_config_values_clear()'.
