# node-bulkregex

CLI for easy application of lots of regexes to a text file  

*Like sed/ed for people who can't be bothered to learn sed/ed*

## Usage

node replace.js  [switches]  

    -i/--input: Input file to execute regexps on. Defaults to stdin.  

    -o/--output: File to save result to. Defaults to stdout.

The replacement file is a JSON file that looks something like this:

```

[{

  "from": "new study",

  "to": "tumblr post"

}, {

  "from": "wheee*!?",

  "to": "whee!"

}, {

  "from": "space",

  "to": "SPAAACE",

  "flags": "gi"

}, {

  "from": "smartphone",

  "to": "pokédex"

}]

```

### Example

Included in the repo is an xkcd-themed replacement file and the full text of the Wikipedia article on computer keyboards. Try it out with this:

```

node replace.js xkcd1031.json -i keyboard.txt -o leopard.txt

```

## Performance

Speedy performance is an important part of any bulk replacement program. I test this one using `benchmark.sh`, included in the repo. On my MacBook Air, it executes in around 300 ms (wall clock time.)
