src/lint/world.bend checks

src/lint/world: everything bolt reads, as one value. The planner (src/lint/plan.bend) is a pure function of a World; the interpreter (src/lint.bend) gathers one, answering each question the planner asks by IO, and prints the plan the planner returns. The design is docs/rfc/bolt-lint-planner.md.

The World holds only what the lint reads: the paths named on the command line, the working directory they are named from, and every answer the interpreter gave. A question with no answer yet reads as a directory with no entries or a file that cannot be read.

Types

type Ask source · line 16 · raw

Data

a question the planner asks. Each is answered by one IO action: a directory listed (src/walk/), or a file read (src/lsp/files/).

Entries
```
@dir:String -> Ask
```
Text
```
@path:String -> Ask
```

type Answer source · line 23 · raw

Data

the answer to one question. A directory that cannot be opened lists as empty, as src/walk/dir.c answers. A text asked of a path that is a directory is Directory, not a read: it has no text.

Listed
```
@names:List<&2, String> -> Answer
```
Read
```
@text:String -> Answer
```
Unread
```
Answer
```
Directory
```
Answer
```

type Reply source · line 30 · raw

Data

one question, answered

Reply
```
@ask:Ask -> @answer:Answer -> Reply
```

type World source · line 36 · raw

Data

everything bolt reads: the paths named on the command line, the working directory (absolute) that relative paths are named from, and every answer the interpreter gave, in the order it gave them
