# trailer

The `trailer` example as shipped in [`examples/trailer/`](https://github.com/loftlang/loft/tree/main/examples/trailer) — 7 files, one project. Every file compiles in CI; a folder here navigates, never scopes.

## `datums/grids.loft`

```loft theme={"theme":{"light":"github-light","dark":"github-dark"},"languages":{"custom":["/languages/loft.json","/languages/loft-fragment.json"]}}
units imperial

level L1 elev 0' height 10'-0"

grid A vertical at 0'
grid B vertical at grid.A + 12'-0"
grid C vertical at grid.B + 12'-0"
grid 1 horizontal at 0'
grid 2 horizontal at grid.1 + 12'-0"
grid 3 horizontal at grid.2 + 10'-0"
```

## `openings.loft`

```loft theme={"theme":{"light":"github-light","dark":"github-dark"},"languages":{"custom":["/languages/loft.json","/languages/loft-fragment.json"]}}

## `views/L1-plan.loft`

```loft theme={"theme":{"light":"github-light","dark":"github-dark"},"languages":{"custom":["/languages/loft.json","/languages/loft-fragment.json"]}}
# A view owns its file — and a viewtype is an ordinary type declaration,
# so the template may sit right beside the one view that applies it.

view A-PLAN L1-plan of level.L1 name "Level 1 Floor Plan"
```
