# Sterling Converts a given D&D 5e currency value to the Silver Standard. Inspired by the Reddit posts titled [The Silver Hack: Making Money Matter](https://www.reddit.com/r/DnDBehindTheScreen/comments/80f6kt/the_silver_hack_making_money_matter/), and [I make Silver Standard for 5th Edition (Spreadsheets.)](https://www.reddit.com/r/dndnext/comments/5tt5g8/i_make_silver_standard_for_5_edition_spreadsheets/). ## Usage ``` USAGE: sterling [FLAGS] [OPTIONS] [VALUE]... [SUBCOMMAND] FLAGS: -o, --optional Include currencies marked as optional when converting -f, --full Print currencies with their full name, rather than with their alias -h, --help Prints help information -V, --version Prints version information OPTIONS: -c, --config Specify location of config file; defaults to './sterling-conf.yml'. ARGS: ... The value to be converted; should be suffixed with the coin's short-hand abbreviation, i.e. p, g, e, s, or c. SUBCOMMANDS: add Add two currency amounts together; uses the currencies defined in your config file copper Calculate the copper value of a custom currency div Divide a currency amount by some scalar divisor; uses the currencies defined in your config file help Prints this message or the help of the given subcommand(s) mul Multiply a scalar multiplicand by a currency amount; uses the currencies defined in your config file sub Subtract two currency amounts from one another; uses the currencies defined in your config file ``` ## Converting Currency Examples ``` // Convert one hundred platinum coins: sterling 100p // 10g // Convert one hundred platinum, fifty gold coins: sterling 100p 50g // 10g, 50s // Convert fifteen thousand copper coins, printing the full names of the coins: sterling -f 15000c // 1 gold, 50 silvers // Convert one platinum, thirty-six gold, twelve electrum, eighty-two silver, and four hundred // sixty-nine copper coins, printing the full names of the coins sterling --full 1p 36g 12e 82s 469c // 64 silvers, 89 coppers // Convert one platinum, thirty-six gold, twelve electrum, eighty-two silver, and four hundred // sixty-nine copper coins, printing the full names of the coins, using the custom config file // detailed below, including optional currencies sterling --full -o -c "~/Documents/D&D/sterling-conf.yml" 1p 36g 12e 82s 469c // 7 guilders, 6 sterling, 25 pence ``` ## Subcommand Examples ``` // Add together ten and twenty pense, using the custom config file detailed below sterling add "10p" "20p" // 30p // Subtract two sterling and ten pence from one eagle sterling --full sub "1e" "2s 10p" // 19 guilders, 25 sterling, 22 pence // Subtract one eagle from two sterling and ten pence. Note that, regardless of order, the smaller // value is ALWAYS subtracted from the larger value. sterling --full sub "2s 10p" "1F" // 19 guilders, 25 sterling, 22 pence // Multiply two sterling and ten pence by thirteen. Note that the currencies always go after the // multiplier. sterling --full mul 13 2s 10p // 1 guilder, 2 sterling, 2 pence // Divide one guilder, 2 sterling, and 2 pence by thirteen. sterling --full div 13 1g 2s 2p // 2 sterling, 10 pence // Convert one note, three eagles, and five guilders into copper sterling copper 1N 3e 5g // 201,600c ``` Note that `sterling` doesn't allow for negative currencies. Therefore, when subtracting currencies, the smaller currency value will always be subtracted from the larger currency value, regardless of the order of the currencies in the `sub` command. ## Custom Currencies `sterling` allows for user-defined currencies, with their own names and conversion rates. By default, `sterling` will look at a file within the current directory called `sterling-conf.yml`, or in whatever location as supplied by the `-c` flag. You can also specify that a currency be optional, which will prevent that currency from being used when converting values, unless the `-o` flag is passed. Below is an example `sterling-conf.yml` file, showing the actual currencies that I use within my own campaign! ``` - name: "note" rate: 143360 alias: "N" optional: true - name: "eagle" rate: 17920 alias: "e" - name: "guilder" rate: 896 alias: "g" - name: "shilling" rate: 32 alias: "s" plural: "sterling" - name: "penny" rate: 1 alias: "p" plural: "pence" ``` Please note that the `rate` value is defined as the number of copper coins that goes into one of that particular currency. In the example above, thirty-two copper coins goes into one "shilling", and eight-hundred ninety-siz copper coins goes into one "guilder". ## Abstract Items and expenses are, by default, assigned arbitrary currency values within the official D&D 5th edition source books. Many of the officially priced items use the "Gold Standard"; that is, items are priced in gold coins by default. While there is nothing wrong with using official currency values within your campaign, it leads to the perceived value of gold to be less in the eyes of your players. Gold has been sought after as both a commodity and a currency for centuries, and your campaign aught to treat gold similarly! ## Explanation The basis of the Silver Standard treats one gold coin from the official D&D 5e source books as one silver coin, and that there are one hundred of a given coin to every one of the next highest valued coin. That's all. Thus, one hundred fifty copper coins equals one silver and fifty copper coins, while a suit of heavy plate armor equals fifteen gold coins, rather than fifteen hundred. ## Installation The easiest way to install `sterling` is to do so with `cargo`, the build tool that's installed along with the `rust` compiler. If you already have `rust` and `cargo` installed onto your computer, simply run the following command from a command prompt: ``` $ cargo install sterling ``` If you do not have the `rust` compiler installed, you can also find pre-built binaries for 64-bit Windows, macOS, and Linux computers in the "Tags" navigation link, which is displayed above this README. Simply download the correct binary for your computer's operating system, extract it somewhere into your file system (such as a "bin" folder within your user directory), and add that location to your system's PATH.
