rena

A hopefully-simple bulk-renaming utility.

Its capabilities currently include dry-run, regex and (simply?) tweaked output.

Requirements

• clap
• color-eyre
• paris
• strfmt
• regex

Usage

The most basic usage is simply rena <folder>, which runs against a folder, renaming everything with the pattern of item_{:10>number}, where number is the item's number when being read.
The padding amount can be adjusted with --padding <number>, and the direction with --padding-direction <direction>, and the prefix with --prefix <prefix>.

It can also run in regex mode, by default as a filter if only --match <regex> is used. If --match-rename <pattern> is also used, it renames everything based on a pattern. The exact syntax is described in --help.

See -h or --help for all flags.

Examples

Currently only has the most basic execution mode covered, I hope to add more.

Most Basic

Let's say there's a directory named images with the following structure:

image.jpg
image3.jpg
12746uju21.jpg
17f29a002.jpg

After running rena images/, it will result in:

item_0000000000.jpg
item_0000000001.jpg
item_0000000002.jpg
item_0000000003.jpg
