실행 방법

먼저 Graphiviz를 설치하고 경로를 통과하십시오.
그리고 다음 명령을 실행하면 출력 대상 폴더에 변환된 여러 파일을 만듭니다.

erdm -output_dir 出力先フォルダパス erdmファイルパス

기술을 이용하다

Go 언어로 구현됩니다.PEG를 erdm 파일의 파서로 사용합니다.
ER 그림 제작은 Graphiviz를 사용합니다.

발동기를 켜다

이 소프트웨어를 개발하는 동기는 다음과 같은 몇 가지가 있다.

소스 코드처럼 차분 관리를 하고 싶다

Go 언어로 뭔가 하고 싶어

PEG

쓰고 싶어요.

DSL 정의 연습

TODO

정형열을 그룹으로 나누기(예를 들어created,creator,updated,updatter 등 그룹)

ER 그림을 테이블 이름으로만 설정하는 옵션(대부분의 테이블 수가 증가하여 읽을 수 있음)

ER 그림의 그룹과 분할(특정 그룹 단위로 관계 표시)

잘못된 내용을 더 쉽게 해석하고 싶다

HTML의 디자인은 누가...

최후

방금 만든 따끈따끈한 소프트웨어니까 버그로 등록해 주세요.
홍보도 기대하고 있다.
