Slate v0.6.0

[0.6.0] - 2026-05-13

Added

Template Mode — custom output filename format

• New "Template mode" toggle in the toolbar activates the TemplateEditor panel, letting you define exactly how renamed files are formatted.
• Type a format string using any combination of the available tokens; the result is previewed live against the first parsed file as you type.
• Click-to-insert token chips make it easy to build a template without typing tokens by hand. Available tokens:
  • {Show} — detected or overridden show name
  • {Season} — season number (no padding, e.g. 1)
  • {SeasonZ} — season number, 2-digit padded (e.g. 01)
  • {Episode} — episode number (no padding)
  • {EpisodeZ} — episode number, padded to 2 or 3 digits; expands to a range for double episodes (e.g. E01-E02)
  • {EpisodeTitle} — episode title when provided
  • {OriginalName} — original filename without extension
• A ✕ reset button appears when the template has been changed, reverting to the default ({Show} - S{SeasonZ}E{EpisodeZ}).
• Template applies in both auto mode and manual mode, so manual-mode rows can also use custom formats.
• The default template produces the same output as previous releases — no behaviour change unless Template mode is enabled.

Parser additions

• New low-confidence patterns for anime file naming conventions:
  • Anime specials: OVA 01, ONA 03, SP 2, Special 4 (season defaults to 1).
  • Japanese episode markers: 第07話 / 第07话 (season defaults to 1).
• trailing-episode-marker warning: when a high-confidence pattern matches but additional episode-like tokens are detected in the remainder of the filename, a structured warning is surfaced in the UI tooltip so the result can be reviewed before renaming.

Scanner

• Hidden files (filenames starting with .) are now excluded from scan results.

Changed

• build-name.ts: applyTemplate() replaces all tokens in a single regex pass, preventing a show name that happens to contain a token literal (e.g. {Show}) from being re-expanded after substitution. buildName() is now a thin wrapper around applyTemplate() using the default template.
• usePreviews: accepts a new template: string argument. All preview rows — in auto mode and manual mode — are computed via applyTemplate rather than the old buildName call, so the live preview always reflects the active template.
• Parser: NNN compact format now requires an explicit word boundary or separator (^, space, ., _, -) on both sides of the three-digit token. This eliminates false positives from codec tags (e.g. h264, x265) and four-digit year values that previously matched in some filenames.
• Undo execution: undo log entry updates now use an indexed map (undoIndexes) for O(1) in-place patching of individual entries before writing, replacing the previous linear scan on each update step.
• Undo semantics: isPendingUndoEntry now treats any entry with a currentPath set (staging temp path written) as a pending undo candidate, even when applied is still false. This covers crash-recovery for cycle/swap operations where the staging rename completed but the final rename did not.

Fixed

• Rename safety: validateOperation now explicitly checks that path.dirname(source) === path.dirname(destination). Any operation that would move a file out of its containing directory is blocked at preflight and surfaced as a blocked issue.
• Rename safety: source files are now inspected via lstatSync instead of statSync, and symbolic link sources are explicitly rejected. This prevents symlink traversal during rename operations.

Tests

• Added parser tests for anime-special markers (OVA, ONA, SP, Special), Japanese episode markers, NNN compact boundary guards, and trailing-episode-marker warnings.
• Added rename preflight test for cross-directory destination blocking.
• Updated scanner test to assert that hidden files (.dot-files) are absent from scan output.
