or _f(x)_.\n\n```sh\nnpm i -g fx\n```\n\nOr use **npx**:\n\n```sh\ncat file.json | npx fx .field\n```\n\nOr use **deno**:\n\n```sh\ncat file.json | deno run -A npm:fx .field\n```\n\n## Usage\n\nFx treats arguments as JavaScript functions. Fx passes the input data to the first\nfunction and then passes the result of the first function to the second function \nand so on.\n\n```sh\necho '{\"name\": \"world\"}' | fx 'x => x.name' 'x => `Hello, ${x}!`'\n```\n\nUse `this` to access the input data. Use `.` at the start of the expression to \naccess the input data without a `x => x` part.\n\n```sh\necho '{\"name\": \"world\"}' | fx '.name' '`Hello, ${this}!`'\n```\n\nUse other JS functions to process the data.\n\n```sh\necho '{\"name\": \"world\"}' | fx 'Object.keys'\n```\n\n### Stream processing\n\nFx can process a stream of json objects. Fx will apply arguments to each object.\n\n```sh\necho '{\"name\": \"hello\"}\\n{\"name\": \"world\"}' | fx '.name'\n```\n\nIf you want to process a stream of json objects as a single array, \nuse the **--slurp** or **-s** flag.\n\n```sh\necho '{\"name\": \"hello\"}\\n{\"name\": \"world\"}' | fx --slurp '.map(x => x.name)' '.join(\", \")'\n```\n\n### Raw input\n\nIf you want to process non-JSON data, use the **--raw** or **-r** flag.\n\n```sh\nls | fx -r '[this, this.includes(\".md\")]'\n```\n\nYou can use **--raw** and **--slurp** (or **-rs**) together to get a single array of strings.\n\n```sh\nls | fx -rs '.filter(x => x.includes(\".md\"))'\n```\n\nFx has a special symbol **skip** for skipping the printing of the result.\n\n```sh\nls | fx -r '.includes(\".md\") ? this : skip'\n```\n\n### Built-in functions\n\nFx comes with a set of useful functions: **uniq**, **sort**, **groupBy**, **chunk**, **zip**.\n\n```sh\ncat file.json | fx 'uniq' 'sort' 'groupBy(x => x.name)'\n```\n\n### Edit-in-place\n\nYou can use special function **save** to edit-in-place the input data.\n\n```sh\nfx file.json 'x.name = x.name.toUpperCase(), x' 'save'\n```\n\nThe edited data will be saved to the same `file.json` file.\n\n### Syntactic Sugar\n\nFx has a shortcut for the map function. Fox example, `this.map(x => x.commit.message)`\ncan be rewritten without leading dot and without `x => x` parts. \n\n```sh\ncurl https://api.github.com/repos/antonmedv/fx/commits | fx 'map(.commit.message)'\n```\n\n```sh\necho '[{\"name\": \"world\"}]' | fx 'map(`Hello, ${x.name}!`)'\n```\n\nFx has a special syntax for the flatMap function. Fox example,\n`.issues.flatMap(x => x.labels.flatMap(x => x))` can be rewritten in the next way.\n\n```sh\ncurl https://fx.wtf/example.json | fx '.issues[].labels[]'\n```\n\n### .fxrc.js\n\nFx supports `.fxrc.js` file in the current directory, or in the home directory, or in XDG config directory.\n\nPut the next code in the `.fxrc.js` file to make `myFunction` available in the fx.\n\n```js\nfunction addOne(x) {\n return x + 1\n}\n```\n\nNow you can use `addOne` in the fx.\n\n```sh\necho '1' | fx addOne\n```\n\nIf you would like to create global variables use `var` instead of `let` or `const`.\n\n## License\n\n[MIT](../LICENSE)\n" }, { "path": "npm/index.js", "content": "#!/usr/bin/env node\n'use strict'\n\nvoid async function main() {\n const os = await import('node:os')\n const fs = await import('node:fs')\n const path = await import('node:path')\n const process = await import('node:process')\n\n let flagHelp = false\n let flagRaw = false\n let flagSlurp = false\n let flagYaml = false\n const args = []\n for (const arg of process.argv.slice(2)) {\n if (arg === '--help' || arg === '-h') flagHelp = true\n else if (arg === '--raw' || arg === '-r') flagRaw = true\n else if (arg === '--slurp' || arg === '-s') flagSlurp = true\n else if (arg === '-rs' || arg === '-sr') flagRaw = flagSlurp = true\n else if (arg === '--yaml') flagYaml = true\n else args.push(arg)\n }\n\n if (flagHelp || (args.length === 0 && process.stdin.isTTY)) {\n return printUsage()\n }\n\n const theme = themes(process.stdout.isTTY ?
