v1.0.0

首个正式版。空格预览 Touchstone S 参数文件（.s1p–.snp、.ts）的频响曲线。

First stable release. Space-to-preview Touchstone S-parameter files (.s1p-.snp, .ts) as frequency-response charts.

内容 Contents

• OxyPlot 参数曲线：Y 轴 dB / 幅值 / 实部 / 虚部 / 相位（°），X 轴线性 / 对数；图例按端口数排成矩阵，可点击显示/隐藏
  OxyPlot traces: Y dB / magnitude / real / imaginary / phase (°), X linear / log; port-count legend matrix, click to toggle
• 跟随 Windows 深浅色 + 系统语言（中文/英文）
  Follows Windows light/dark mode + system language (zh/en)
• Touchstone v1.1 / v2.x 解析：RI / MA / DB，跨行数据归并，[Noise] 块
  Touchstone v1.1 / v2.x parsing incl. wrapped rows and [Noise] blocks
• 大文件保护：绘图抽稀、警告封顶
  Large-file guardrails: plot decimation, warning caps

Full Changelog: v0.2.0...v1.0.0

v0.2.0

What's changed since v0.1.0

UI

• Removed the top filename box (name already in the QuickLook window title); file summary moved to the plot subtitle, parser warnings to a slim amber bar (only when non-empty, capped at 4)
• Added a legend (OxyPlot 2.x needs an explicit legend entry)
• Axis options (Y: dB/magnitude/real/imaginary/phase, X: linear/log) restyled as flat segmented tabs
• Follows Windows app mode: light/dark theme adapts the plot, grid, tabs, legend and tracker tooltip
• Readable hover tooltip (the stock pale-yellow box with inherited near-white text was white-on-yellow in dark mode)

Parser / robustness

• Fixed wrapped multi-line data (4-port+ files spanning several physical lines) — value-only lines were being misread as new points / negative frequencies (regression-tested from a real s4p file)
• Warning cap (100 in parser, 4 shown in UI) so pathological files can't bloat the UI
• Plot decimation to <=4000 points/series so huge files don't freeze OxyPlot

Bug fixes

• Fixed 'Failed to preview': WPF freezes SolidColorBrush once used by the render layer; theme switching now replaces the ResourceDictionary entry instead of mutating the frozen brush (Multi-commit hunt, root cause in the exception log)
• Panel init hardened so theme/BAML failures can't kill the preview

v0.1.0

Initial release.

Press Space on Touchstone S-parameter files (.s1p-.snp, .ts) to preview frequency-response charts (OxyPlot) plus a data table.

Install: quit QuickLook, unzip the .qlplugin into %AppData%\pooi.moe\QuickLook\QuickLook.Plugin\QuickLook.Plugin.SnpViewer, restart QuickLook. (Spacebar-install via the .qlplugin file itself is also supported.)

Requires QuickLook 4.x (Installer build) on Windows.
