For me, a good tabletop role-playing game (RPG), sometimes called a pen-and-paper RPG, is the perfect hobby for getting away from my computer. The classic editions of Dungeons & Dragons (D&D), for example, were released well before PDFs and eBooks existed, so I bring hardcover books and paper character sheets to my gaming table.
In recent years, however, I've also started gaming online using Mumble voice chat. At first, I treated these games the same as my in-person games, but as more games started integrating online maps like Mythic Table, I found switching back and forth between keyboard-and-screen and pen-and-paper became a little frantic. When I'm running a player character (PC), most of what I need to refer to is on a character sheet, a document that lists my special abilities and powers. To get to that information quickly while managing a bunch of other applications, I use the
pc command parses RPG character sheets written in the INI format. It works with any RPG game system, as long as that system's character sheet data can be expressed as basic INI (most of them can be).
Install the pc command
$ chmod +x src/pc.pl $ sudo mv src/pc.pl /usr/local/bin/pc
You can alternately use
$ mkdir build $ cd build $ cmake .. $ cmake --install .
Build characters in INI
pc to be able to parse your character's stats, you must build or document your PC in the INI format. INI is a simple text format that consists of a heading in brackets and a group of key and value pairs. For example, here's a portion of a D&D character sheet:
[Character] Name=Tristan Ancestry=Human Background=Urchin Class=Paladin Level=8 [Health] HP=35 Max.HP=68 AC=19 [Stat] STR=+2 DEX=0 CON=+2 INT=-1 WIS=+3 CHA=+4
All of this is for your own reference, so you don't have to adhere to anything but the general INI format. You can include stats that aren't on the paper version of your character sheet or even just write personal reminders to yourself as comments. Make your INI character sheet work for you, and let
pc do the rest.
Once you've got your character sheet, save it, with the
.ini extension, to

List your character sheets
pc, you can get a list of all the character sheets you have saved:
$ pc --list Abbadon.ini Dreadmax.ini NPC_1076.ini NPC_1077.ini Tristan.ini Zoe.ini
Get a stat
When you roll dice in an RPG, you often have to adjust your roll according to your character sheet. For instance, if you're attacking an evil orc, you might roll 10 on your 20-sided die and then add a number to represent your physical strength. To get your Strength value (often abbreviated as STR), provide the character name and the stat you want to see. Character names are case-sensitive, so if your character is saved as
Tristan.ini, the character name is Tristan and not tristan or TRISTAN.
$ pc Tristan STR STR=2
You now know that you must add two to your roll.
Unique and non-unique stats
As long as a stat is unique, you don't have to type out the whole string. For instance, if the only stat in your character sheet starting with Max is
Max.HP, then you can just type
Max or possibly even
pc can usually figure out what you want.
$ pc Tristan Ma Max.HP=68
However, many game systems use the same stat for different attributes. For instance, in D&D, your Wisdom (WIS) may be significant for both Wisdom-based skills and Wisdom-based saving throws. In other systems, both armor and weapons could have a level assigned to them. Non-unique stats return ambiguous results:
$ pc Tristan WIS WIS=3 WIS=5
[ Free eBook: Manage your Linux environment for success. ]
If a stat you need is non-unique, you can specify the category you want first to narrow down the result:
$ pc Tristan Save WIS WIS=5 $ pc Tristan Stat WIS WIS=3
View a whole category
If you want to see several related stats, you can view an entire category at once by just specifying it. As long as it's sufficiently unique, you don't have to type the whole word:
$ pc Tristan Hea [Health] HP=42 Max.HP=68 AC=19
To see a list of categories in your character sheet, use the
-c for short) option:
[Character] [Health] [Stat] [Save] [Skills] [Proficiencies] [Immune] [Lang]
You can omit all arguments to see the whole character sheet:
$ pc Tristan [Character] Name=Tristan Ancestry=Human Background=Urchin Class=Paladin Level=8 [Health] HP=42 Max.HP=68 AC=19 [...]
Update a stat
Most role-playing games require that you track certain statistics as you play. For instance, when battling a group of baddies, your health or hit points (HP) probably go down as you take hits. In other systems, you might earn points in a skill as you utilize and gain experience with it.
pc is by no means intended to be an editor, it can perform minor changes for you. To update a stat, use the
-s for short):
$ pc Tristan HP HP=68 $ pc Tristan HP --set 60 HP=68 HP updated to 60 $ pc Tristan HP HP=60
Easy character management
There are many ways to manage a character for an RPG, including the open source character generator PCGen, the traditional pen and paper method, and specialized websites. The
pc command is another way for you to keep track of data, and for me, it feels like a natural and convenient method that fits into how I manage most of the data in my real life. Give
pc a try the next time you sign up for an online game, and if you're a Perl programmer, see what new features you might be able to add to it.
