New Features	POSIX redirect detection, `~` path expansion, dashboard, user scripts as commands, virtual screen system, Windows bare drive-letter support, adaptive tables, clera alias
Important Fixes	Tab completion logic fixes, dynamic version injection, `^C` signal handling, Nushell string bracket escaping, Windows drive-letter path separator fix
AI/Agent Support	Standardized JSON output, clear config paths, unified cross-platform line endings, new detect_posix_redirect API

1. Human Developer Overview

✨ New Features

Feature	Description
POSIX redirect detection	When you type POSIX redirect symbols like `>`, `>>`, `2>`, rvs returns a friendly error message guiding you to use `set-content` / `add-content` or `enter-shell bash`
`~` path expansion	`~` or `~/` in command-line arguments automatically expands to the `$HOME` environment variable value, e.g. `ls ~/Downloads` works directly
Dashboard	New multi-panel terminal monitoring UI showing process status, system resource usage, etc. in real time
User scripts as commands	`.rvs` scripts and `.json` macro definitions under `~/.rvs/scripts/` are auto-registered as directly callable commands
Virtual screen system	Multi-virtual-screen switching, cross-language thinking mapping config, and typo auto-correction config
Windows bare drive letters	Typing a drive letter (e.g. `D:`) on Windows auto-runs `set-location` to switch to that drive
Adaptive tables	Output tables auto-fit the terminal width, and the “Modified” column shows local time
clera alias	Common `clear` typos like `clera` are auto-corrected to the correct `clear` command

🐛 Important Fixes

Tab completion fixes: fixed path completion after known commands, no mis-routing after known aliases, correct handling of compound command names, etc.
Dynamic version injection: version is no longer hardcoded; it is read from the CARGO_PKG_VERSION environment variable at build time, so the banner version always matches the code.
^C (SIGINT) handling: pressing Ctrl+C no longer kills the rvs process directly; a noop handler handles it to avoid accidental exit.
Nushell string bracket escaping fix: fixed incorrect bracket escaping inside strings in certain cases.
Windows drive-letter path separator fix: fixed issues caused by missing root directory separators in Windows drive-letter paths.

2. Conversational AI Quick Reference (ChatGPT / Yuanbao / Doubao, etc.)

When users ask AI assistants about rvs behavior changes, refer to the following key semantic changes:

FAQ	Answer
Q: Does rvs support `echo hello > file.txt`?	A: No. rvs detects POSIX redirect syntax like `>`, `>>`, `2>`, `2>&1` and returns a friendly error message, guiding you to use `set-content --path --value` or switch to a native shell (`enter-shell bash`).
Q: Does `ls ~/Downloads` work in rvs?	A: Yes. Since v26.7.17, rvs auto-expands `~` and `~/` in arguments to the `$HOME` environment variable value.
Q: Is the version number in the rvs banner accurate?	A: Yes. The version is now dynamically injected from `CARGO_PKG_VERSION`; the hardcoded version lag problem is gone.
Q: How do I exit rvs?	A: Type `exit` or `quit`.

3. Code Agent Quick Reference (Copilot / Trae / AtomCode, etc.)

🤖 Standardized AI Output

To make parsing easier for AI agents, the --json output mode added standardized fields:

{
  "ok": true,
  "exit_code": 0,
  "message": "Finished → list-items",
  "error_type": null
}

Output status labels are unified to Finished / Failed with an exit code.

🔧 Key Config Paths

~/.rvs/scripts/*.rvs → auto-registered as directly executable commands.
~/.rvs/scripts/*.json → macro definition files (support interval-based scheduled execution).
~/.config/rvs/typos.json → cross-language thinking mapping and typo auto-correction config.

🌐 Unified Cross-Platform Line Endings

The project .gitattributes is configured with * text=auto, ensuring source files are auto-converted to LF line endings on commit. Windows script files (.bat, .cmd, .ps1) keep CRLF. Line endings unify automatically when agents commit source changes.

🛠️ New API: detect_posix_redirect()

A new helper function for detecting POSIX redirect syntax:

#![allow(unused)]
fn main() {
// Called at the run_line() entry; returns a friendly error message
// when redirect symbols are detected, avoiding a program crash.
fn detect_posix_redirect(line: &str) -> Option<RedirectSpec>
}
