XML Menu Diff

Install

Install using pip (>= 19.0).

pip install --upgrade pip
pip install git+https://github.com/cms-l1-globaltrigger/[email protected]

Basic usage

Compare the content of two XML trigger menus.

tm-diff [-f|--format <format>] [-s|--skip <mode>] [--sort <key>]
        [-d|--dump] [-o <file>]
        <file1> <file2>

Format

Use flag -f|--format <format> to select diff output format. Options are:

• unified for unified diff format
• context for contextual diff format
• html for a complete diff in as HTML file
• report to be copy-pasted into TWiki reports

Default format is unified.

Example:

tm-diff ... -fhtml -o diff.html  # dumps diff as HTML table to file

Skip

Use flag -s|--skip <mode> to ignore certain attributes. Options are

• module to skip implementation details (attributes uuid_firmware, n_modules, module_id, module_index)
• comment to skip comments (attribute comment)
• labels to skip algorithm labels (attribute labels)

Example:

tm-diff ... -smodule -scomment  # ignores module_is/index and any comments

Sort

Use flag --sort <key> to sort algorithms by attribute. Options are

• index to sort by algorithm index
• name to sort by algorithm name
• expression to sort by algorithm expression

Default sort kay is index.

Dump

Use flag -d|--dump to dump the raw text used to diff the menu contents. This option will create two text files with the menu names at the current working location.

Example:

tm-diff foo.xml bar.xml -d  # dumps raw text to foo.xml.txt bar.xml.txt

Output

Use flag -o <file> to write the output to a file.

Example:

tm-diff foo.xml bar.xml -o diff.txt  # write output to file

This is equivalent to:

tm-diff foo.xml bar.xml > diff.txt  # pipe stdout to file
