- Reuse value slices in place instead of clear()+realloc when a map's
key set is static (skipped when scripts may mutate the maps).
- Use SetBodyString to drop the []byte(Body) copy, build the Cookie
header with a strings.Builder, and skip QueryArgs when no params.
- Cache the values map when all values are literal, and share one empty
map when none are configured.
- Reuse a single bytes.Buffer across template renders per worker.
- --log-level (comma-separated string: info, error): pick which logs are emitted;
the level set is resolved once, up front
- Log responses at the info level: full self-contained JSON to a file or stderr,
a compact "status duration | body" summary in the TUI log box
- Route logs independently of the progress display: the TUI log box when it runs,
stderr when piped, or a file via --log-file/-w (parent dir validated up front)
- Replace --quiet with --progress (bar | none, default bar): progress and logs are
now independent — progress=none still shows the log box; quiet == progress=none
with an empty log level
- Rename the internal "message" concept to "log" (runtimeLog, runtimeLogger, ...)
First signal cancels the main context; second releases the terminal
and exits 130, unblocking shutdown when captcha polls or user scripts
ignore context. Also moves the bubbletea models and streamProgress
out of sarin.go into a new tui.go.
- Rename Append to Merge on Cookies, Headers, and Params types and simplify Parse to use direct append
- Replace strings_Join(sep, ...values) with slice_Join(slice, sep) for consistency with slice-based template functions
- Auto-enable quiet mode when stdout is not a terminal
- Remove ErrCLINoArgs check to allow running sarin without arguments
- Add -it flag to Docker examples in docs
Refactor request generators to populate a script.RequestData intermediate struct, then apply it to fasthttp.Request in one step. This eliminates the round-trip conversion (fasthttp → RequestData → fasthttp) when scripts are enabled. Remove the URL field from RequestData and the now-unused fasthttp conversion functions from chain.go.
Replace ad-hoc fmt.Errorf/errors.New calls with typed error structs across config, sarin, and script packages to enable type-based error handling. Add script-specific error handlers in CLI entry point. Fix variable shadowing bug in Worker for scriptTransformer. Bump Go to 1.25.7 and golangci-lint to v2.8.0.
- Add FileCache for caching local files and remote URLs in memory
- Update body_FormData to accept variadic key-value pairs with file support
- Use @ prefix for file paths (local or HTTP/HTTPS URLs)
- Use @@ to escape literal @ values
- Add file_Base64 function for Base64 encoding files
- Update documentation with new syntax and examples
