When --root points to a directory that is itself a git repo (has a .git subdirectory), treat it as a single repo instead of treating each subdirectory as a separate repo. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

All four columns in the function tables (Repo, File, Class, Function) are now hyperlinked: - Repo links to the repository root - File links to the file at the exact line range - Class links to the file (for context) - Function links to the file at the exact line range Also adds GitHub remote URL support alongside existing ADO support. GitHub URLs use the blob/branch/path#L1-L10 format. The default branch is auto-detected via git symbolic-ref. Repo breakdown table also hyperlinks repo names. Fixes the single-repo case where the repo name column was blank. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Repos with legacy visualstudio.com remotes (e.g., msdata.visualstudio.com/DefaultCollection/Project/_git/Repo) are now correctly parsed and converted to dev.azure.com URLs for hyperlink generation. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Path.GetFileName returns empty string when the path ends with a directory separator (e.g., C:\src\PerfBenchInfra\). This caused the repo column to be blank in the HTML report. Added a regression test that confirms the bug (fails before fix, passes after). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Added per-command option tables, single-repo vs multi-repo examples, two-step workflow (analyze once, adjust thresholds), custom output paths, and hyperlink/remote URL documentation. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Resolves the nearest .csproj/.fsproj/.vbproj for each source file by walking up the directory tree. Results are cached per directory for performance. The column is blank for non-.NET languages (Python, TypeScript, etc.) where project boundaries are less well-defined. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Report order is now: summary cards, per-repo breakdown, language breakdown, distribution charts, then the detail tables (combined risk, long functions, high complexity). Summary data comes first, details as you scroll down. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Each function table (combined risk, long functions, high complexity) now has a repo dropdown alongside the text filter. Both filters work together -- selecting a repo narrows the rows, and typing further filters within that repo. The dropdown only appears when there are multiple repos.

Themes available via --theme CLI option and an in-page dropdown: - dark: original dark GitHub-like theme - light: clean light theme - colorblind: blue/orange/brown palette, no red-green reliance - high-contrast: pure black background, maximum contrast - ink: minimal color, print-friendly All color semantics use CSS variables (--severity-ok, --severity-medium, --severity-high, --severity-critical, --bar-1 through --bar-5) so every theme can define its own accessible palette. The theme switcher in the page header allows instant switching without regeneration. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Lizard CSV output has 11 columns (not 10): the parser was reading the 'long name' field as the start line, which failed int parsing and caused every line to be silently skipped. Fixed by using parts[^2] and parts[^1] for start/end line numbers. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Changed table container from overflow:hidden to overflow-x:auto so wide tables scroll horizontally instead of clipping. Widened max container to 1600px, tightened cell padding and font size slightly to fit more columns, and added white-space:nowrap on td to prevent mid-cell wrapping.

Function tables now group rows by repo with a separator heading row instead of repeating the repo name in every row. This drops a column (9 instead of 10) and makes the tables easier to scan. The repo heading spans all columns, is styled distinctly, includes a count badge, and links to the repo root. The repo dropdown filter works with the data-repo attribute on both separator and data rows. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Each repo gets a concern score based on the number and severity of flagged functions: - Combined risk (both thresholds): 10 points each - Complex only: 3 points each - Long only: 2 points each - Bonus points for extreme values (2x threshold) Report structure is now: 1. Summary cards 2. Repository Ranking table (sorted by concern score, worst first) with clickable links to each repo's detail section 3. Language breakdown and distribution charts 4. Per-repo detail sections (only for repos with issues), each with its own Combined Risk, Long Functions, and High Complexity tables 5. Clean repos listed at the bottom This makes the report much easier to read with 50+ repos since you see the worst offenders first and can drill into each repo independently.

Both options accept a regex pattern (use | for OR) and are applied to file paths (normalized with forward slashes) during scanning. --include keeps only matching paths; --exclude skips matching paths. Filters apply to both Roslyn C# analysis and Lizard results. Examples: --include "src/dev" --exclude "Tests?|Generated|\.Designer\." --include "ProjectA|ProjectB" Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Filters now match against repo/folder names rather than individual file paths. Non-matching repos are skipped entirely (with a 'Skipping ... (filtered)' message) and excluded from all totals. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Deleted LizardRunner.cs and removed all Lizard references from Program.cs, README, and csproj. The --csharp-only flag is no longer needed. Multi-language support may be added later with a different tool. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Bar chart text is now white for readability on all colored bars. Concern score badges use severity colors with bold weight instead of muted text. Combined Risk heading clarified to 'Combined Risk (Long + Complex)'. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Critical/high/medium scores get colored backgrounds (red/orange/ yellow) with white text. Low scores stay subtle with green text. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Swap the tile/card grid for a single-row table showing key stats inline: '57 repos 7,630 files 36,469 functions 89 long 479 complex 24 combined risk'. Flagged counts are color-coded by severity. Compact, readable, no visual clutter. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Each repo with flagged functions now gets its own length and complexity distribution charts. The global distribution section is removed. Also updated complexity buckets to align with the new default threshold of 25. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Projects ending in 'Tests' or 'Test' are excluded from analysis by default. Use --include-tests to include them. File counts in the report reflect only non-test files. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Repository names in the ranking table now anchor-link to the repo's detail section within the report. The per-repo detail heading still links to the actual external repo URL. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
When the root directory contains subdirectories that are not git repos (organizational folders like babylon/ and sentinel_graph/), descend one level to find actual repos. Direct child repos are still handled as before. Repo names now use the relative path from root (e.g., babylon/RepoName) to disambiguate repos with the same name across org folders. Lifecycle metadata lookup falls back to the leaf name for backward compatibility. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Update default threshold-complexity from 15 to 25 to match code. Rewrite HTML Report section to reflect actual structure: summary table, repository ranking, and per-repo details with distribution charts and function tables. Add missing CLI options (--include-tests, --repo-metadata, --theme on report command). Rename AppendSummaryCards to AppendSummaryTable and remove unused .cards CSS class.

ComplexityRipper
Roslyn-based code complexity analyzer for C#. Scans repos for long functions, high cyclomatic complexity, and deep nesting. Generates self-contained HTML reports with hyperlinks to source files in Azure DevOps and GitHub.
Features
Analysis: Uses Roslyn syntax tree parsing for accurate cyclomatic complexity, line count, nesting depth, and parameter count. Finds methods, constructors, property accessors, and local functions. Resolves the nearest .csproj for a Project column.
Report: Self-contained HTML with theme switcher (light, dark, high-contrast, ink). Repos ranked by concern score (worst first), with per-repo detail sections containing Combined Risk, Long Functions, and High Complexity tables. All columns hyperlinked to source in ADO or GitHub. Sortable and filterable tables with distribution charts.
Concern Score: Weighted composite per repo -- 10 pts per combined-risk function, 3 pts per complex-only, 2 pts per long-only, plus bonus for extreme values. Repos with score 0 are listed as clean.
Filtering: \--include\ and \--exclude\ regex options filter by repo name (use \|\ for OR). Non-matching repos are skipped entirely.
CLI: Three commands -- \
un\ (analyze + report), \�nalyze\ (JSON only), \
eport\ (HTML from JSON). Configurable thresholds, themes, and output paths. Packaged as a dotnet global tool.
Project structure (ToListinator conventions)
\Directory.Build.props\ for centralized versioning, \Directory.Packages.props\ for package management, CI + release GitHub Actions workflows, \.editorconfig\, MIT license, modern \.slnx\ solution format. 41 xUnit tests.
