📖 csv read

CVSS v3.0CVSS v3.1text output

Synopsis

cvss csv read reads CVSS vectors from a CSV file (or stdin) and prints each parsed vector string on its own line. The CSV format puts the vector string in the first column. By default the command fails on the first invalid row; pass --lax to skip invalid rows and report them as warnings instead.

csv is the parent command for CSV I/O; read is its reader subcommand (the sibling is csv write).

How It Works

The CSV is read row by row; strict mode fails on the first invalid row, while --lax skips bad rows and reports them as warnings, returning the valid vectors and an error list.

Usage

cvss csv read [file] [flags]

Flags

Flag	Default	Description
--lax	false	tolerant mode: skip invalid rows instead of failing
-h, --help	—	help for read

Examples

Read a CSV file

cvss csv read input.csv

From stdin

cat vectors.csv | cvss csv read -

Tolerant mode

cvss csv read --lax messy.csv

Default vs --lax

In strict (default) mode, the first malformed row aborts the read with an error. In --lax mode, malformed rows are skipped and reported on stderr as Warning: ...; all valid rows are still parsed and printed.

Underlying API

import "github.com/scagogogo/cvss-skills/pkg/cvss"

// Strict mode — fails on the first invalid row.
vectors, err := cvss.ReadCSV(os.Stdin) // ([]*Cvss3x, error)
if err != nil {
    log.Fatal(err)
}
for _, cv := range vectors {
    fmt.Println(cv.String())
}

// Tolerant mode — skips invalid rows, collects warnings.
vectors, readErrors, err := cvss.ReadCSVLax(os.Stdin) // ([]*Cvss3x, []CSVReadError, error)
if err != nil {
    log.Fatal(err)
}
for _, cv := range vectors {
    fmt.Println(cv.String())
}
for _, e := range readErrors {
    fmt.Fprintln(os.Stderr, "Warning:", e.String())
}

cvss.ReadCSV(r io.Reader) ([]*Cvss3x, error) is the strict reader. cvss.ReadCSVLax(r io.Reader) ([]*Cvss3x, []CSVReadError, error) is the tolerant reader — it returns parsed vectors alongside a []CSVReadError describing each skipped row, and only returns a non-nil error for I/O or structural CSV failures.
