Samlingen Docs

Docs: Docs är Overleafs interna term för en redigerbar fil, till exempel en ren tex-fil eller en .bib-fil. Den lagrar filens innehåll, revisionsinformation och raderingsstatus.

​

Grundläggande identifiering

• _id: Unikt MongoDB-ObjectId som identifierar denna dokumentpost.
• project_id: Referens till projektet (Project._id) som filen tillhör.
• name: Filnamnet som det visas i projektets filträd (t.ex. main.tex, sample.bib).

​

Revision och versionshantering

• rev: Revisionsnummer för detta dokument i projekthistoriken.
• version: Intern schema- eller formatversion som används av editorns backend.

Dessa fält används av Overleafs egna versionshanteringssystem för att spåra stegvisa ändringar och stödja historik och återställning.

​

Filinnehåll

• lines:
  En array av strängar som representerar filens innehåll rad för rad.
  Varje element motsvarar en logisk rad i källfilen.

  I det här exemplet lagras en BibTeX-post:

  • @article{greenwade93, ... }

• ranges: Datastruktur reserverad för editorannoteringar eller spårade intervall
  (t.ex. markeringar, kommentarer eller ändringsspårning). Tom när inga aktiva intervall finns. op är ett operationsobjekt som knyter kommentaren till en specifik position i dokumentet.

  • op.c — Den kommenterade markerade texten (teckeninnehåll)
  • op.p — Ankarposition (teckenförskjutning)
  • id Unikt ObjectId för denna kommentarspost.
  • metadata Information om författare och tidsstämpel.

​

Raderingsstatus

• deleted:
  Anger om dokumentet har raderats från projektet.
• deletedAt:
  Tidsstämpel som registrerar när dokumentet raderades.

Raderade dokument behålls vanligtvis för återställning av historik och bläddring bland versioner i stället för att omedelbart tas bort från databasen.

Här är ett verkligt exempel på ett Overleaf-docs.
