Simple Golang/Buffalo HTTP-server that returns online programming problems from different platforms in a form of unified JSON.
corgi-api mostly uses its own web scrappers (due to the lack of the official APIs).
Example of a parsed problem:
http://127.0.0.1:3000/problem?source=timus&problem_title=2035
{

"TimeLimitMs": 500,

"SourceSizeLimit": "64 KB",

"OutputFile": "",
"Description": "Now Kirill has to recover the lost tests as soon as possible. He has answers to the tests, and he remembers that the summands A and B were integers such that 0 ≤ A ≤ X and 0 ≤ B ≤ Y. Help Kirill recover the tests!",
"InputDescription": "The only input line contains integers X, Y, and C separated with a space (0 ≤ X, Y, C ≤ 109).",
"OutputDescription": "If Kirill is wrong and there are no such integers, output “Impossible” (without quotation marks). Otherwise, output the integers A and B separated with a space. If there are several pairs satisfying the conditions, output any of them.",
"Examples": [
{
"Input": "2 7 5",

},

"Input": "9 15 100",
"Output": "Impossible"
}

Adding a new platform is extremly easy. You just have to follow these 3 steps:
- Add your new platform in the
ds/sources.go
file - Go to
parsers
package folder, and create here new file called<your platform>.go
. Here, you should write a functionfunc Parse<Your platform>Problem(problemID *ds.ProblemID) (ds.ProblemData, error)
. You can useparser/codeforces.go
as an example. - Go to
parser/parser.go
. Add your new platform function to theproblemFunctions
map.
