Usage

``` ojcmp 0.2.2

USAGE: ojcmp [FLAGS] [OPTIONS] --std

FLAGS: -a, --all Reads all bytes of user file even if it's already WA -b, --backtrace Prints stack backtrace when fatal error occurs -h, --help Prints help information -V, --version Prints version information

OPTIONS: --eps Eps for float comparing -m, --mode CompareMode ("normal"|"strict"|"spj_float") [default: normal] -s, --std Std file path -u, --user User file path. Reads from stdin if it's not given ```

Return Value

| type | value | | ------ | ------------------------------------------ | | code | errno | | stdout | "AC" / "WA" / "PE" | | stderr | error message and optional stack backtrace |

Current Implementation

Mode: Normal

trim_end(file)

rust judge!(AC, b"1\r\n\r\n\r\n", b"1 ");

for each line, trim_end(line)

rust judge!(AC, b"1 \n", b"1");

for each line, check spaces between non-space chars

rust judge!(PE, b"1 3\n", b"1 3\n");

Mode: Strict

User file must have the same bytes with std file.

The two byte streams must be exactly the same.

There is no "PE" in this mode.

Mode: SpjFloat

Compare two streams of float numbers which are splitted by ascii whitespaces.

Parse any float number as f64 (aka double in C language).

Ascii whitespaces between two float numbers are considered as a single separator symbol.

Use CLI option --eps to specify eps value, for example --eps 1e-3.

There is no "PE" in this mode.
