Edit: /home/techb158/.nvm/versions/node/v16.20.2/lib/node_modules/npm/lib/commands/completion.js (9124B)

// Each command has a completion function that takes an options object and a cb
// The callback gets called with an error and an array of possible completions.
// The options object is built up based on the environment variables set by
// zsh or bash when calling a function for completion, based on the cursor
// position and the command line thus far.  These are:
// COMP_CWORD: the index of the "word" in the command line being completed
// COMP_LINE: the full command line thusfar as a string
// COMP_POINT: the cursor index at the point of triggering completion
//
// We parse the command line with nopt, like npm does, and then create an
// options object containing:
// words: array of words in the command line
// w: the index of the word being completed (ie, COMP_CWORD)
// word: the word being completed
// line: the COMP_LINE
// lineLength
// point: the COMP_POINT, usually equal to line length, but not always, eg if
// the user has pressed the left-arrow to complete an earlier word
// partialLine: the line up to the point
// partialWord: the word being completed (which might be ''), up to the point
// conf: a nopt parse of the command line
//
// When the implementation completion method returns its list of strings,
// and arrays of strings, we filter that by any that start with the
// partialWord, since only those can possibly be valid matches.
//
// Matches are wrapped with ' to escape them, if necessary, and then printed
// one per line for the shell completion method to consume in IFS=$'\n' mode
// as an array.
