MirrorMan aims to provide a seamless solution for mirroring and converting a large hierarchy of files.
You might use this for:
- Converting your lossless audio library to smaller MP3s to be taken on the go (see
example_filter.sh) - Upscaling footage from your super-duper old video camera and converting into a reasonable format
- Turning your SD card full of raw images into the things normal people can view
To make a new mirror: mirrorman init {source} {mirror_path} [filters...]
To sync existing mirrors, from within a directory with .mmdb files: mirrorman sync
Filters are the core of the conversion side of things.
They tell mirrorman if a file should be converted and the new file extension after conversion.
(They also perform the actual important conversion part.)
A filter is just an executable program that has two operation modes:
{filter} ext {input_extension}->output_extension: Prints the desired extension, or returns an error code if the filter doesn't care about the input file.{filter} run {input} {ouput}: Converts the input file to the output file.
It's really that simple!
Refer to the example filter for specifics.
- Use timestamp comparisons before hash comparisons on database
- Better way of a filter ignoring a file, error codes should ideally be used for errors not passing info
