I need some help parsing a document
I'm planning to create a database (SQL) to hold metadata for video games that I can then export data to/from various formats used by different frontends. Most of the code is rather easy as I know how to use SQL already and XML (used by most frontends) is pretty straight forward. I'm having an issue with one of the Frontend formats though. Pegasus Frontend metafile docs Here. It uses Debian control file format.

For index, line in StrSplit(str, "`n")
RegExMatch(line, "(.+?): *(.*)", part), arr[part1] := part2

Thanks. That would work when there is one value per line. But almost any key can also be plural making it a list which would have its values listed one per line starting on or after the line the key is on. Values like "description" can have multiple lines and also a single "." on a line to mark paragraphs. This seems like it should be really simple... Writing the document is very easy. I wish parsing it was to.

You have described the input but not an example of the intended output.
Re: I need some help parsing a document
SQL database is the final resting place for the data. I got that part covered. I need to turn each "game" entry into an object with keys matching the metafile keys. The rest of the code is already there for the most part. Or turn the whole file into an object. Like JSON.Load(file).

The goal is to shoot down enemy airplanes and collect weapon power-ups (POW). One is only able to perform three loops per level and a bonus is awarded at the end of the level for unused loops. Player 1 uses a P-38 Lightning and Player 2 uses a Mosquito Mk IV. The game shifts from the original Pacific Front setting with that of the Western Front.

The game consists of six levels.

It was the first shoot 'em up to add +1 to the score when a continue is used.[1]

description:
Gran Turismo 2 is fundamentally based on the racing game genre. The player must maneuver an automobile to compete against artificially intelligent drivers on various race tracks. The game uses two different modes: arcade and simulation. In the arcade mode, the player can freely choose the courses and vehicles they wish to use. However, the simulation mode requires the player to earn driver's licenses, pay for vehicles, and earn trophies in order to unlock new courses. Gran Turismo 2 features nearly 650 automobiles and 27 racing tracks.

description:
In Grand Theft Auto, you assume the role of a street thug working for an organized syndicate of criminals that specializes in stealing cars. Every time your pager beeps, the boss needs you to steal something for him -- if you don't get to a payphone and answer the message, you'll be in hot water (or is that cold water at the bottom of the East River).
After receiving your mission, you'll have to navigate city streets that are bustling with pedestrians, cops (your worst enemies), and traffic jams. Because you're pressed for time, you can't just walk to your destination on foot -- that would take too long. Instead, you'll have to go car jacking, the art of physically removing people out of their vehicles and stealing it.
.

.
This is the premise behind Grand Theft Auto, an overhead action game of thievery. There are four large cities in which you'll have to steal cars, shoot rival gang members, and complete missions for the boss. Each mission requires you to get something from point "A" to point "B". For example, the head honcho wants to pull off a bank heist -- instead of using regular cars, they want you to steal a couple taxicabs for them. This way, the cops won't be able to find them as easily in traffic.

Nice, thank you. I'll run that through some full files when I get a chance. I found the code they are using in the frontend to parse the file. Looks like the keys are all hardcoded and regex is used.
