A Visual Studio Code extension that monitors build log files for errors and displays them in VS Code's Problems panel.

• Auto monitoring: Watches build log files for changes and automatically parses new content
• Custom wildcard log paths: Configurable paths to log files including wildcard patterns.
• Custom problem patterns: Configurable problem matcher patterns to identify different types of build errors with file locations, line numbers, and severity
• VS Code integration: Displays errors in the Problems panel with clickable links to source files. Also supports related information for errors.

The extension provides the following commands accessible via the Command Palette (Ctrl+Shift+P):

• WatchBuildLog: Start Watching Build Log - Begin monitoring the configured log file
• WatchBuildLog: Stop Watching Build Log - Stop monitoring and clear error diagnostics

Configure the extension through VS Code settings:

• Type: array
• Default: ["out/*/siso_output"]
• Description: Glob-style wildcard patterns for build log files. Patterns can be absolute paths or relative to the project root. Use '*' to match any text in a folder segment.
• Scope: Resource (can be set per workspace)
• Examples:
  • "out/*_x64/siso.log" - Matches siso.log in any subfolder of out/ that ends with _x64
  • "build/*/errors.log" - Matches errors.log in any direct subfolder of build/
  • "C:/logs/*.log" - Absolute path matching any .log file in C:/logs/

• Type: boolean
• Default: true
• Description: Automatically start watching when VS Code opens

• Type: array
• Description: Problem matcher patterns similar to VS Code's task system. Each pattern defines a regex and capture group indices for extracting error information from build logs.

1. Configure log file patterns:

   • Open VS Code Settings (Ctrl+,)
   • Search for "watchbuildlog"
   • Add wildcard patterns to "Log File Path Wildcards" (default includes "out/*/siso_output")
   • Or add to your settings.json: "watchbuildlog.logFilePathWildcards": ["out/*_x64/siso.log", "build/*/errors.log"]

2. Start watching: The extension auto-starts by default, or run "Start Watching Build Log" command manually

3. View errors: Build errors will appear in the Problems panel (Ctrl+Shift+M)

4. Navigate to errors: Click on errors in the Problems panel to jump to the source location

1. Via Settings UI:

   • Open Settings (Ctrl+,)
   • Search for "Watch Build Log" or "watchbuildlog"
   • Configure all extension settings through the UI

2. Via JSON Settings:

   {
     "watchbuildlog.logFilePathWildcards": [
       "out/*_x64/siso.log",
       "build/*/errors.log",
       "C:/absolute/path/to/build.log"
     ],
     "watchbuildlog.autoStart": true,
     "watchbuildlog.problemMatcherPatterns": [
       {
         "regexp": "^(.*)\\((\\d+),(\\d+)\\)\\s*:\\s*([^: ]+)[^:]*:\\s*(.*)$",
         "file": 1,
         "line": 2,
         "column": 3,
         "severity": 4,
         "message": 5
       }
     ]
   }

• "out/*_x64/siso.log" - Matches out/Debug_x64/siso.log, out/Release_x64/siso.log, etc.
• "build/*/logs/*.log" - Matches any .log file in any subfolder of build/*/logs/
• "**/build.log" - Matches build.log in any subdirectory at any depth
• "logs/*" - Matches any file directly in the logs folder
