A console line utility to rename all files in current directory according to a supplied format string.

Format string syntax consists of any characters excluding '{' and '}', and special identifiers. For now, the supported identifiers include:

• {name} - old name
• {number} - sequence number
• {date} - today's date

File extensions are preserved.

The program will halt if changing a name would overwrite another file.

• Clone this repository

• Install Stack if you haven't yet done so

• Run stack install in the repo's folder

rename -vhe --dry-run [-p pattern] [format string]

Say we start with a folder contatining these files:

• abc.jpg
• def.pdf
• ghi.xml

We would get these results:

• rename {name} -> [abc.jpg, def.pdf, ghi.xml] (no change)
• rename file_{number} -> [file_1.jpg, file_2.pdf, file_3.xml]
• rename -e {name}_{number} -> [abc_1, def_2, ghi_3]
• rename "{name} ({date})" -> "abc (2019-10-16).jpg" and so on
