# Cấu hình nâng cao
Trong khi Starship là một shell linh hoạt, đôi khi bạn vẫn cần làm nhiều hơn là chỉnh sửa `starship.toml` để có thể là được những việc nhất định. Tài liệu này sẽ mô tả chi tiết các tùy chỉnh nâng cao trong starship.
::: cảnh báo
Các tùy chỉnh được mô tả trong phần này có thể sẽ thay đổi trong các phiên bản tương lai của Starship.
:::
## Tùy chỉnh các hàm được thực thi trước prompt và các lệnh Linux mặc định của bash shell
Bash không có một preexec/precmd framework chính thống giống như các shells khác. Do đó rất khó để cung cấp các hook với khả năng tuỳ biến hoàn toàn cho `bash` shell. Tuy nhiên, Starship cho phép bạn viết các hàm riêng của bạn để tùy biến việc render prompt:
- Để thực thi một hàm custom trước khi prompt được render, ta cần định nghĩa một hàm mới và gán `starship_precmd_user_func` cho tên của hàm này. Ví dụ, để vẽ một tên lửa trước prompt
```bash
function blastoff(){
echo "🚀"
}
starship_precmd_user_func="blastoff"
```
- Để thực thi một hàm custom trước khi một câu lệnh Linux chạy, ta có thể sử dụng cơ chế bẫy tín hiệu [`DEBUG`](https://jichu4n.com/posts/debug-trap-and-prompt_command-in-bash/). Tuy nhiên, bạn **phải** đặt bẫy tín hiệu DEBUG *trước* khởi tạo Starship! Starship có thể giữ giá trị của DEBUG trap, nhưng nếu trap bị ghi đè sau khi starship khởi động, một vài chức năng sẽ không hoạt động.
```bash
function blastoff(){
echo "🚀"
}
trap blastoff DEBUG # Bẫy DEBUG *trước khi* starship chạy
eval $(starship init bash)
```
## Thay đổi tên gọi trên cửa sổ của chương trình terminal
Một vài shell có khả năng tự động thay đổi tên hiển thị (chẳng hạn như tên của thư mục hiện thời) trên cửa số của trình mô phỏng terminal. Fish shell mặc định thực hiện thay đổi này. Tuy không được set mặc định trên Starship, chức năng này có thể được tích hợp dễ dàng trên `bash` shell và `zsh` shell.
Đầu tiên, ta cần định nghĩa một hàm thay đổi tiêu đề cửa sổ (dùng chung cho cả bash và zsh):
```bash
function set_win_title(){
echo -ne "\033]0; YOUR_WINDOW_TITLE_HERE \007"
}
```
Ta có thể sử dụng biến số để tuỳ chỉnh tên hiển thị này (`$USER`, `$HOSTNAME`, và `$PWD` là những biến số thường được dùng).
Với `bash` shell, set precmd của starship bằng tên của hàm này:
```bash
starship_precmd_user_func="set_win_title"
```
Với `zsh` shell, thêm hàm này vào mảng `precmd_functions`:
```bash
precmd_functions+=(set_win_title)
```
Nếu ta hài lòng với các tùy biến đã được thiết lập, thêm những dòng sau vào cấu hình shell (`~/.bashrc` hoặc `~/.zshrc`) để thực thi chúng mỗi khi ta khởi tạo một shell mới.
Ví dụ, nếu ta muốn hiển thị đường dẫn thư mục hiện tại trong tiêu đề của một terminal tab, thêm đoạn code sau vào `~/.bashrc` hoặc `~/.zshrc`:
```bash
function set_win_title(){

## Các chuỗi kiểu
Chuỗi kiểu là một danh sách các từ, được phân cách bởi khoảng trắng. Các từ là không phân biệt hoa thường (ví dụ. `bold``Bold` là hai chuỗi tương đương). Mỗi từ có thể là một trong các từ sau:
- `bold`
- `nghiêng`
- `gạch dưới`
- `làm tối đi`
- `đảo ngược`
- `bg:<color>`
- `fg:<color>`
- `<color>`
- `none`
`<color>` là một nơi quy định màu (được bàn luận ở phía dưới). `fg:<color>` and `<color>` currently do the same thing, though this may change in the future. `inverted` swaps the background and foreground colors. Thứ tự các từ trong chuỗi là không quan trọng.

Từ mã `none` ghi đè tất cả các từ mã khác trong chuỗi nếu nó không là một phần của `bg:` specifier, vậy nên `fg:red none fg:blue` sẽ vẫn tạo một chuỗi mà không có kiểu. `bg:none` sets the background to the default color so `fg:red bg:none` is equivalent to `red` or `fg:red` and `bg:green fg:red bg:none` is also equivalent to `fg:red` or `red`. Nó có thể trở thành một lỗi để sử dụng `none` trong việc kết hợp với các từ mã khác trong tương lai.
Một quy định màu có thể là một trong các thứ sau:
- Một tròn các màu chuẩn của terminal: `black`, `red`, `green`, `blue`, `yellow`, `purple`, `cyan`, `white`. Bạn có thể tuỳ chọn những tiền tố này với `bright` để có được phiên bản sáng hơn (ví dụ: `bright-white`).
- Một `#` được theo sau bởi một số thập lục phân gồm sáu chữ số. Cái này quy định một [mã thập lục phân cho màu RGB](https://www.w3schools.com/colors/colors_hexadecimal.asp).
- Một số nằm giữa 0-255. Cái này quy định một [mã màu ANSI 8-bit](https://i.stack.imgur.com/KTSQa.png).
Nếu nhiều màu được quy định cho màu chữ/màu nền, cái cuối cùng trong chuỗi sẽ được ưu tiên.
