Tern

Tern is a modular batch conversion interface

Disclaimer

Tern is now in a usable status (beta), so no guarantees; also, some features are incomplete.

Features

• Recursively scans and converts files from a specified directory
• Incrementally updates converted files
• Converter: Outsources conversion work to an external program (scriptable through Lua)
• Stores and manages options related to the external program
• Converts only modified files and allows to select files through git ignore patterns
• Destination of output files is customizable

Installation

1. Clone the repository and cd into it
2. Run: cargo install --path . --locked

Ensure you have the latest nightly compiler, tested on 1.85.0-nightly

Usage

Converters are manually created by the user and must be placed under converters found in the project's data directory.

tern # Runs configured conversion engines; if there is no such configuration, `tern` is resolved to `tern --profile-manager`
tern -h # Prints help

Demo

-- /home/user/.local/share/tern/converters/pandoc.lua
function concat_with_space(...)
  return table.concat({...}, " ")
end

function convert(input, output, options)
    local command = concat_with_space("pandoc", options[1], input, "-o", output)
    return os.execute(command)
end

return convert
