Workspace Log Parser

This tool is used to inspect and parse the Bazel workspace logs. To generate the workspace log, run e.g.,:

    bazel build \
        --experimental_workspace_rules_log_file=/tmp/workspace.log :hello_world

Then build the parser and run it.

    bazel build src/tools/workspacelog:all
    bazel-bin/src/tools/workspacelog/parser --log_path=/tmp/workspace.log

This will simply print the log contents to stdout in text form.

To output results to a file, use --output_path:

    bazel-bin/src/tools/workspacelog/parser --log_path=/tmp/workspace.log \
        --output_path=/tmp/workspace.log.txt

To exclude all events produced by a certain rule, use --exclude_rule:

    bazel build src/tools/workspacelog:all
    bazel-bin/src/tools/workspacelog/parser --log_path=/tmp/workspace.log \
        --exclude_rule "//external:local_config_cc"

Note that --exclude_rule may be specified multiple times.

    bazel build src/tools/workspacelog:all
    bazel-bin/src/tools/workspacelog/parser --log_path=/tmp/workspace.log \
        --exclude_rule "//external:local_config_cc" \
        --exclude_rule "//external:dep"

For example, the above will filter out any events produced by rules //external:local_config_cc or //external:dep
