Rapidquilt

This is very specialized reimplementation of quilt & patch in one. It supports only the push command. The goal is to be very fast.

Usage

Usage: rapidquilt push [<options>] [num|patch]

Options:
    -a, --all           apply all patches in series

    -d, --directory DIR working directory

    -p, --patch-directory DIR
                        directory with patches (default: "patches")

    -b, --backup always|onfail|never
                        create backup files for `quilt pop`
                        (default: onfail)

        --backup-count all|<n>
                        amount of backup files for `quilt pop` to create
                        (default: 100)

    -F, --fuzz <n>      maximal allowed fuzz (default: 0)

        --color always|auto|never
                        use colors in output (default: auto)

        --dry-run       do not save any changes

    -A, --analyze ANALYSIS
                        run additional analysis while patching. You can use
                        this option multiple times to run multiple analyses at
                        once. Available analyses: multiapply

        --stats         print statistics in the end

    -q, --quiet         only print errors

    -v, --verbose       print extra information. Repeat for more verbosity. It
                        may affect performance.

        --mmap          mmap files instead of reading into buffers. This may
                        reduce memory usage and improve performance in some
                        cases. Warning: You must ensure that no external
                        program will modify the files while rapidquilt is
                        running, otherwise you may get incorrect results or
                        even crash.

    -h, --help          print this help menu

Limitations compared to quilt & patch

• only the push command
• only patches in unified format
• date in patch files is ignored
• endlines must be the same in patch and patched file (e.g. both "\n" or both "\r\n") (always --binary mode)
• ... probably more that I don't know about
