@mfranzke/replaceinfiles v1.1.7

replace-in-files

Please note that this is a fork of the @songkick/replaceinfiles package, which should mainly fix a problem encountered on pure npm ecosystems (one of its subdependencies referenced a package from github.com directly).

Utility to replace a map of strings in many files

Use cases:

• pipe from hashmark to replace references to hashmarked files - see example
• replace dev environment paths to production
• inject values in a config file

Not actively worked on

We're happy to accept PRs and suggestions, but be aware that this project is no longer used internally and therefore not actively maintained + improved by Songkick.

Usage

Install

npm i replaceinfiles

Create or generate a replace map, save in a file or pipe to stdin

{
  "foo": "bar",
  "hello": "goodbye",
  "world": "earth",
  "%API_URL%": "https://myservice.com/api"
}

Run

Usage: replaceinfiles [options]

Options:

    -h, --help                     output usage information
    -V, --version                  output the version number
    -s, --source <glob>            glob matching files to be updated
    -d, --dest-pattern <path>      pattern to output files
    -o, --output-path <path>       path to output report file default: stdout
    -S, --silent                   do not output report
    -r, --replace-map-path <path>  path to replace map json, default: stdin
    -e, --encoding <string>        used for both read and write, default "utf-8"

Examples

• Streaming replace map from stdin

  cat replace-map.json | replaceinfiles -s src/*.css -d 'dist/{base}'

• Getting replace map from file

  replaceinfiles -r replace-map.json -s src/*.css -d 'dist/{base}'

• Write report to a file

  replaceinfiles -r replace-map.json -s src/*.css -d 'dist/{base}' > report.json
  # or
  replaceinfiles -r replace-map.json -s src/*.css -d 'dist/{base}' -o report.json

Report

replaceinfiles generates a report on stdout or specified path for you to pipe other tools if you need to.

Here is an example:

{
  "options": {
    "source": "test/src/*.txt",
    "destPattern": "test/dist/{base}",
    "outputPath": null,
    "replaceMapPath": null,
    "replaceMap": {
      "hello": "goodbye",
      "world": "earth"
    },
    "encoding": "utf-8"
  },
  "result": [
    {
      "src": "test/src/one.txt",
      "dest": "test/dist/one.txt",
      "changed": true
    },
    {
      "src": "test/src/three.txt",
      "dest": "test/dist/three.txt",
      "changed": false
    },
    {
      "src": "test/src/two.txt",
      "dest": "test/dist/two.txt",
      "changed": true
    }
  ]
}

Options details

-s, --source: A glob matching the files you want to replace from

-d, --dest-pattern: A pattern to define updated files destination. You can use all the path.parse() result values (root, dir, name, base, ext), example: -d './dist/{dir}/{name}.build{ext}'

-r, --replace-map-path: Path to a replace map JSON file ({'stringToReplace': 'replaceWithThat', '..', '...'}). stdin is used as default.

-o, --output-path: A path to write the report, default is stdout

-S, --silent: Do not output report, bypasses -o

-e, --encoding: Used for both read and write, default: utf-8

API

You can also run replaceinfiles from node.

var replaceinfiles = require('replaceinfiles');

var options = {
  source: './test/*.txt',
  destPattern: './test/dist/{base}',
  replaceMap: {
    foo: 'bar'
  }
  // or, specify a path to your replaceMap json file
  // replaceMapPath: './map.json'
};

replaceinfiles(options)
  .then(function(report){
    // ...
  })
  .catch(function(error) {
    // ...
  });

If you do not specify replaceMap or replaceMapPath then stdin will be used.
