node-orn's Introduction

orn

If you know JavaScript RegExp, you know orn, a file renamer just like String.prototype.replace(<pattern>, <replacement>) in cli.

Usage

Usage: orn <pattern> <replacement> [-d]

Arguments:

  <pattern>          The pattern to be replaced, could be a String or RegExp.
  <replacement>      The String to be replace with, Arrow Function is supported.

Options:

  -h, --help         Output usage information
  -v, --version      Output the version number
  -d, --dry-run      Show how the files will be renamed, but actually do nothing

Examples:

  orn 720p 1080P                        # Replace "720p" with "1080P".
  orn /720p/i 1080P                     # Replace "720p" or "720P" with "1080P".
  orn '/(\.js)$/i' '.min$1' -d          # Add ".min" to js files, in dry-run.
  orn '/\S+mp3$/' 'x=>x.toLowerCase()'  # Change mp3 filename to lowercase.

Switches

-d, --dry-run
Show how the files will be renamed, but actually do nothing.

Feature Enhancement - iteration and padding

I love orn, however it doesn't do everything I'd like it to do. I'd like to be able to generate number sequences and I'd like to be able to pad outputs. One use case for this sort of functionality is when you have a large number of shows you'd like to provide season / episode naming for.

Let's say you have a naming convention like:

001 - Episode name
...
101 - Episode name

and these episode are kept in folders like

Season1
Season2
...

Where season1 has 001 - 024, season2 has 025 - 048, etc.

One might want to change the naming to be formatted as follows:

S01E01 - Episode name
...
S01E024 - Episode name

S02E01 - Episode name
...
S02E24 - Episode name

Now I have modified my orm to allow me to do this. To accomplish this I changed the

return isArrowFn ? vm.runInNewContext(string) : string

line to

return isArrowFn ? vm.runInThisContext(string) : string

I added a global pad function (so you can access it from the new vm):

pad = function (n, width, z) {
z = z || '0';
n = n + '';
return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
}

I also added the global:

line = 0;

This allows me to use orm as follows:

orn '/\d\d\d/' 'x=>S01E${pad(++line, 2, 0)}'

Which changes

001 - Episode name ---> S01E01 - Episode name

I'm not altogether happy with my solution, but this was just me hacking things together for my personal needs. There's probably a better more general approach to adding iteration and padding. I think these two features would be a HUGE win for the tool. :)
