Changelog

All notable changes to this project will be documented in this file.

[0.8.0] - 2026-05-17

Added

  • --theme CLI flag overrides the theme setting from the config file. Pass lazyenv --theme=dracula to apply a theme for one run without editing your .lazyenvrc. Unknown theme names produce a warning on stderr.
  • Config validation now rejects malformed [colors] values. Each color must be a hex literal (#RGB, #RGBA, #RRGGBB, #RRGGBBAA) or an ANSI 256 number (0-255). Previously, typos like primary = "blue" silently shipped to lipgloss and rendered as blank.

Fixed

  • parser.Marshal no longer injects a trailing newline that wasn't there. Files saved by scripts or editors that don't end with \n (e.g. echo "X=1" > .env) now round-trip faithfully, removing the spurious one-byte git diff lazyenv used to produce on first save. Files that did have a trailing newline still keep one.
  • parser.WriteFile now fsyncs the temp file before renaming it over the target. Without the sync, a crash between rename and the filesystem journal flush could leave a zero-byte file on ext4 and similar filesystems.
  • --no-theme-bg=false now correctly restores the theme background when the config file already had no-theme-bg = true. The theme + background precedence is now resolved in a single late step after CLI overrides, so any combination of config and CLI flags lands on the expected color.

Changed

  • Source-default version is now "dev" instead of a stale release number. Local go run . / just build binaries print lazyenv version dev (...) so they can't be mistaken for an official release. GoReleaser overrides this via ldflags for tagged builds.
  • CLI-flag warnings (unknown --theme, out-of-range --file-list-width) now surface in the TUI's config-warning alert at startup instead of being written to stderr, which the TUI screen would obscure until exit.
  • --check-config no longer exits with status 1 when no configuration file is found. Lazyenv works fine on defaults, so the absence of a file is now reported on stdout and the process exits 0. Exit 1 is reserved for configs that are present but invalid, so CI pipelines using lazyenv --check-config && work as expected even on repos without a .lazyenvrc.

[0.7.1] - 2026-05-06

Changed

  • Variable grouping: when sort is alphabetical (o), groups are now ordered alphabetically by prefix instead of by file position. The Ungrouped bucket remains pinned last. Pressing o also keeps the cursor on the same var (or same group header) when groups shift. This also affects startup behavior when both sort = "alphabetical" and group = true are set in the config — groups now appear in alphabetical order from the first render.

[0.7.0] - 2026-05-03

Added

  • Variable grouping by prefix in the var list. Toggle with g: variables sharing a prefix (DB_*, REDIS_*, ...) are grouped under collapsible headers (▾ DB (4) / ▸ DB (4)). Variables with a unique prefix or no _ collect under a trailing UNGROUPED header (shown only when at least one named group exists). Press enter or space on any header to collapse/expand it; click a header with the mouse for the same effect. Groups appear in file order; alphabetical sort applies inside each group. Search disables grouping in rendering and restores it on clear. Set group = true in config or pass -g / --group to start with grouping enabled.

Fixed

  • Help screen: aligned n/N and Space/Enter action rows under the actions column.

[0.6.0] - 2026-04-19

Added

  • Session summary on exit: prints a per-file recap of disk-level changes (added/changed/deleted vars, created/deleted/renamed files, duplicates with post-create diff, templates) to stdout when you quit. Silent if nothing changed. Disable with session-summary = false in config or --no-session-summary CLI flag; --read-only forces it off.

[0.5.4] - 2026-04-11

Added

  • Control characters in values (\n, \t, \r) render as width-1 glyphs (↵, ⇥, ↩) in the variable list and compare view, keeping multiline values on a single row.

Fixed

  • Multiline single-quoted values (KEY='line1\nline2') were truncated at the first line on parse. Compare between two files whose values shared a first line falsely reported equality.
  • Copying a multiline value in compare mode and saving corrupted the target file — the writer emitted raw control bytes for unquoted values, breaking the .env format on re-read.
  • Values containing newlines or tabs broke the variable panel row layout and pushed status indicators off their row.
  • Masked secrets showed replacement character glyphs at narrow column widths because the column truncator sliced mid-UTF-8 sequence.
  • truncate panicked on negative column widths.

[0.5.3] - 2026-04-06

Added

  • Rename variable key inline (E key) with validation and duplicate detection
  • Variable count shown right-aligned in file list panel
  • File and variable counts in panel titles (Files (5), .env (12 vars), filtered 3/12 vars)

Changed

  • Variable panel status bar hints: removed compare/matrix/help (discoverable via ?), added E rename

[0.5.2] - 2026-04-05

Added

Changed

Added
