Build & Clean Examples

How dtk filters dotnet build and dotnet clean output.

How to read these examples. Every pair below is captured from a real run against the projects in samples/, and ExamplesBindingTests replays each Raw block through the real filter on every build, so a page cannot drift from what the tool actually prints. Absolute paths are rewritten to /repo to keep the captures machine-independent, and a non-zero exit code is noted beside the command that produced it.

Why the raw output may not look like your terminal. When dotnet writes to a terminal it uses the .NET terminal logger, which prints a compact live-updating summary. When its output is redirected — which is exactly what dtk does — MSBuild falls back to the classic console logger shown here, which prints each diagnostic twice: once inline and again in the end-of-build summary. That duplication is a large part of what dtk removes.

Log files: when the output is too large to display, dtk writes the full output to a log file. Pass --show-log to print its path.

Incremental builds skip re-emitting warnings, so dotnet clean must precede this run to capture them. Warnings are grouped by code rather than by file: the frequency counts surface the most common pattern first.
