# readseek
`readseek` is a structural source reader for scripts, editors, and coding agents.
It emits pretty-printed JSON with stable `LINE:HASH` anchors, structural symbol
maps, parse diagnostics, AST search matches, references, and rename plans.
Current documented CLI API: **0.4.x**.
## Install
```sh
npm install -g @jarkkojs/readseek
```
Or build the native binary from source:
```sh
cargo build --release
```
## Common commands
```sh
readseek detect src/main.rs
readseek read src/main.rs --start 10 --end 20
readseek map src/main.rs
readseek check src/main.rs
readseek symbol src/main.rs --name run
readseek identify src/main.rs:42 --column 8
readseek def src run --language rust --format plain
readseek refs src main --language rust --format plain
readseek search src 'fn $NAME() { $$$BODY }' --language rust
readseek rename src/main.rs --line 42 --column 8 --to renamed
```
Use `--stdin <path>` with `detect`, `read`, `map`, `check`, `symbol`, and
`identify` to analyze unsaved editor buffers while still providing a path for
language detection:
```sh
printf '%s\n' 'fn main() {}' | readseek identify --stdin scratch.rs --line 1 --column 4
```
Use `def --from-identify` to pipe `identify` JSON into definition lookup:
```sh
## Images
`detect` reports format, dimensions, and animation status for images. Add a vision
flag to analyze image contents with the embedded Florence-2 model:
```sh
readseek detect screenshot.png --transcribe # text + per-region bounding quads
readseek detect photo.jpg --caption # detailed natural-language caption
readseek detect photo.jpg --objects # object labels + bounding boxes
```
The flags can be combined; the model loads once per invocation. The model is
embedded in the binary, so no download or network access is required at runtime.
Inference is CPU-only and takes a few seconds per image.
## Cache
`readseek init [path]` creates a `.readseek/` directory containing map cache files
under `maps/` and definition-index shards under `def-index/`. Commands discover
that directory by walking up from the target path, or use the directory passed by
`--readseek-dir`.
## Documentation
The manual page is the authoritative CLI reference:
```sh
man man/man1/readseek.1
```
Pass `--help` to any command for command-specific usage.
