+
+Rich 是一款提供終端機介面中 _豐富的_ 文字效果及精美的格式設定的 Python 函式庫。
+
+[Rich API](https://rich.readthedocs.io/en/latest/) 讓終端機介面加上色彩及樣式變得易如反掌。Rich 也可以繪製漂亮的表格、進度條、Markdown、語法醒目標示的程式碼、Traceback（追溯）……。
+
+
+
+關於 Rich 的介紹，請參見 [@fishnets88](https://twitter.com/fishnets88) 在 [calmcode.io](https://calmcode.io/rich/introduction.html) 錄製的影片。
+
+[看看其他人對於 Rich 的討論](https://www.willmcgugan.com/blog/pages/post/rich-tweets/)。
+
+## 相容性
+
+Rich 可在 Linux、macOS、Windows 上運作。在新的 Windows Terminal 中可支援顯示全彩及 Emoji，但傳統的終端機中僅支援 16 色。Rich 最低需要的 Python 版本為 3.6.1。
+
+Rich 可在 [Jupyter notebooks](https://jupyter.org/) 上使用，無須額外設定。
+
+## 安裝
+
+以 `pip` 或 PyPI 套件管理器安裝。
+
+```sh
+python -m pip install rich
+```
+
+以此命令測試 Rich 在終端機的輸出效果：
+
+```sh
+python -m rich
+```
+
+## Rich Print
+
+匯入 [rich print](https://rich.readthedocs.io/en/latest/introduction.html#quick-start) 方法就可以輕鬆地讓程式進行 rich 輸出，rich print 與 Python 內建的函式用法相似。試試：
+
+```python
+from rich import print
+
+print("Hello, [bold magenta]World[/bold magenta]!", ":vampire:", locals())
+```
+
+
+
+## Rich REPL
+
+Rich 可以安裝在 Python REPL 中，如此一來就可以漂亮的輸出與突顯標示任何資料結構。
+
+```python
+>>> from rich import pretty
+>>> pretty.install()
+```
+
+
+
+## 使用 Console
+
+匯入並建構 [Console](https://rich.readthedocs.io/en/latest/reference/console.html#rich.console.Console) 物件，以更全面地控制 rich 終端機內容。
+
+```python
+from rich.console import Console
+
+console = Console()
+```
+
+Console 物件有個 `print` 方法，且刻意設計的與內建 `print` 函式相似。參考此範例：
+
+```python
+console.print("Hello", "World!")
+```
+
+如同預期的，這會將 `"Hello World!"` 印在終端機。須注意不同於內建的 `print` 函式，Rich 會自動將過長的文字換行，以符合終端機的寬度。
+
+有幾種加上顏色及樣式的方式。您可以用 `style` 引數設定輸出內容的樣式，參考此範例：
+
+```python
+console.print("Hello", "World!", style="bold red")
+```
+
+輸出結果如下圖：
+
+
+
+介紹完了如何對整行文字設定樣式，接著來看看更細部的使用。Rich 可以接受類似 [bbcode](https://en.wikipedia.org/wiki/BBCode) 的語法，對個別文字設定樣式。參考此範例：
+
+```python
+console.print("Where there is a [bold cyan]Will[/bold cyan] there [u]is[/u] a [i]way[/i].")
+```
+
+
+
+您可以用 Console 物件不費吹灰之力地達成細膩的輸出效果。參閱 [Console API](https://rich.readthedocs.io/en/latest/console.html) 說明文件以了解細節。
+
+## Rich Inspect
+
+Rich 提供了 [inspect](https://rich.readthedocs.io/en/latest/reference/init.html?highlight=inspect#rich.inspect) 函式，可以對任何 Python 物件，如 class、instance 或 builtin ，為其產生一份報告。
+
+```python
+>>> my_list = ["foo", "bar"]
+>>> from rich import inspect
+>>> inspect(my_list, methods=True)
+```
+
+
+
+參閱 [inspect 說明文件](https://rich.readthedocs.io/en/latest/reference/init.html#rich.inspect) 以了解細節。
+
+# Rich 函式庫
+
+Rich 包含了一系列可繪製的物件，您可以使用它們來印出精美的畫面，或者協助偵錯程式碼。
+
+按一下子標題以了解細節：
+
+
+Log
+
+Console 物件提供了 `log()` 方法，使用方式與 `print()` 類似，但還多了一欄來顯示目前時間、進行呼叫的檔案及行號。預設情況下 Rich 會語法醒目標示 Python 的結構及 repr 字串。若使用於字典或串列這類集合性物件，Rich 會將其漂亮地印出來，以符合可用空間。此範例示範了這些功能。
+
+```python
+from rich.console import Console
+console = Console()
+
+test_data = [
+ {"jsonrpc": "2.0", "method": "sum", "params": [None, 1, 2, 4, False, True], "id": "1",},
+ {"jsonrpc": "2.0", "method": "notify_hello", "params": [7]},
+ {"jsonrpc": "2.0", "method": "subtract", "params": [42, 23], "id": "2"},
+]
+
+def test_log():
+ enabled = False
+ context = {
+ "foo": "bar",
+ }
+ movies = ["Deadpool", "Rise of the Skywalker"]
+ console.log("Hello from", console, "!")
+ console.log(test_data, log_locals=True)
+
+
+test_log()
+```
+
+上面的程式碼會產生下圖結果：
+
+
+
+注意到 `log_locals` 引數，可用來輸出一張表格，用來顯示 log 方法被呼叫時，區域變數的內容。
+
+log 方法可用於伺服器上長時間運作的程式，也很適合一般程式偵錯用途。
+
+
+
+Logging Handler
+
+您也可以使用內建的 [Handler 類別](https://rich.readthedocs.io/en/latest/logging.html) 來將 Python logging 模組的輸出內容格式化並賦予色彩：
+
+
+
+
+
+
+Emoji
+
+以一對冒號包住表情符號的名稱，來透過 console 插入 Emoji。參考範例：
+
+```python
+>>> console.print(":smiley: :vampire: :pile_of_poo: :thumbs_up: :raccoon:")
+😃 🧛 💩 👍 🦝
+```
+
+請謹慎使用此功能。
+
+
+
+
+表格
+
+Rich 可以用 unicode box 字元繪製彈性的 [表格](https://rich.readthedocs.io/en/latest/tables.html)。格式設定十分多元，包含框線、樣式、儲存格對齊……。
+
+
+
+上圖的動畫效果是以 [table_movie.py](https://github.com/willmcgugan/rich/blob/master/examples/table_movie.py) 產生的，該檔案位於 examples 資料夾。
+
+參考這個簡單的表格範例：
+
+```python
+from rich.console import Console
+from rich.table import Table
+
+console = Console()
+
+table = Table(show_header=True, header_style="bold magenta")
+table.add_column("Date", style="dim", width=12)
+table.add_column("Title")
+table.add_column("Production Budget", justify="right")
+table.add_column("Box Office", justify="right")
+table.add_row(
+ "Dec 20, 2019", "Star Wars: The Rise of Skywalker", "$275,000,000", "$375,126,118"
+)
+table.add_row(
+ "May 25, 2018",
+ "[red]Solo[/red]: A Star Wars Story",
+ "$275,000,000",
+ "$393,151,347",
+)
+table.add_row(
+ "Dec 15, 2017",
+ "Star Wars Ep. VIII: The Last Jedi",
+ "$262,000,000",
+ "[bold]$1,332,539,889[/bold]",
+)
+
+console.print(table)
+```
+
+執行結果如圖：
+
+
+
+請留意，主控台標記的呈現方式與 `print()`、`log()` 相同。事實上，由 Rich 繪製的任何東西都可以被放在任何標題、列，甚至其他表格裡。
+
+`Table` 類別很聰明，能夠自動調整欄寬來配合終端機的大小，也會在需要時自動將文字換行。此範例的程式碼與上一個相同，然而終端機變小了一點：
+
+
+
+
+
+
+進度條
+
+Rich 可繪製多個不閃爍的 [進度條](https://rich.readthedocs.io/en/latest/progress.html)，以追蹤需時較久的工作。
+
+基本的使用方式，是將序列放在 `track` 函式中，再對其結果疊代。參考此範例：
+
+```python
+from rich.progress import track
+
+for step in track(range(100)):
+ do_step(step)
+```
+
+新增多個進度條也不是難事，來看看說明文件中的範例：
+
+
+
+您可以調整要顯示的狀態欄位。內建的欄位包含完成百分比、檔案大小、讀寫速度及剩餘時間。來看看另一個用來顯示下載進度的範例：
+
+
+
+想嘗試看看嗎？您可以在 [examples/downloader.py](https://github.com/willmcgugan/rich/blob/master/examples/downloader.py) 取得此範例程式。此程式可以在下載多個檔案時顯示各自的進度。
+
+
+
+
+狀態
+
+有些狀況下很難估計進度，就可以使用 [status](https://rich.readthedocs.io/en/latest/reference/console.html#rich.console.Console.status) 方法，此方法會顯示「spinner」動畫及訊息。該動畫播放時，仍可正常操作主控台。參考此範例：
+
+```python
+from time import sleep
+from rich.console import Console
+
+console = Console()
+tasks = [f"task {n}" for n in range(1, 11)]
+
+with console.status("[bold green]Working on tasks...") as status:
+ while tasks:
+ task = tasks.pop(0)
+ sleep(1)
+ console.log(f"{task} complete")
+```
+
+終端機的顯示效果如下：
+
+
+
+該 spinner 動畫乃借用自 [cli-spinners](https://www.npmjs.com/package/cli-spinners)。可以用 `spinner` 參數指定 spinner 樣式。執行此命令以顯示可用的值：
+
+```
+python -m rich.spinner
+```
+
+此命令在終端機的輸出結果如下圖：
+
+
+
+
+
+
+樹
+
+Rich 可以用導引線繪製一棵 [樹](https://rich.readthedocs.io/en/latest/tree.html)。樹很適合用來顯示檔案結構，或其他繼承性的資料。
+
+可以用文字或其他 Rich 能繪製的元素作為樹的標籤。執行下列程式碼來看看效果：
+
+```
+python -m rich.tree
+```
+
+這會產生下圖的結果：
+
+
+
+您可以參考 [tree.py](https://github.com/willmcgugan/rich/blob/master/examples/tree.py) 範例程式，此程式可以樹狀圖展示目錄結構，如同 Linux 的 `tree` 命令。
+
+
+
+
+資料欄
+
+Rich 可以將內容呈現於整齊的 [資料欄](https://rich.readthedocs.io/en/latest/columns.html) 中，其欄寬可為等寬或最適寬度。此範例仿作了 macOS / Linux 系統中 `ls` 命令的基本功能，可以用資料欄列出目錄：
+
+```python
+import os
+import sys
+
+from rich import print
+from rich.columns import Columns
+
+directory = os.listdir(sys.argv[1])
+print(Columns(directory))
+```
+
+此螢幕截圖為 [資料欄範例](https://github.com/willmcgugan/rich/blob/master/examples/columns.py) 的輸出結果。此程式從某 API 取得資料，並以資料欄呈現：
+
+
+
+
+
+
+Markdown
+
+Rich 可以繪製 [Markdown](https://rich.readthedocs.io/en/latest/markdown.html) 並處理了將其轉換為終端機格式的大量工作。
+
+先匯入 `Markdown` 類別，再以內容為 Markdown 語言的字串建構一個物件，接著將其印到 console。參考此範例：
+
+```python
+from rich.console import Console
+from rich.markdown import Markdown
+
+console = Console()
+with open("README.md") as readme:
+ markdown = Markdown(readme.read())
+console.print(markdown)
+```
+
+執行結果如下圖：
+
+
+
+
+
+
+語法醒目標示
+
+Rich 使用了 [pygments](https://pygments.org/) 函式庫來實作 [語法醒目標示](https://rich.readthedocs.io/en/latest/syntax.html) 功能。使用方式與繪製 Markdown 相似，先建構 `Syntax` 物件並將其印到 console。參考此範例：
+
+```python
+from rich.console import Console
+from rich.syntax import Syntax
+
+my_code = '''
+def iter_first_last(values: Iterable[T]) -> Iterable[Tuple[bool, bool, T]]:
+ """Iterate and generate a tuple with a flag for first and last value."""
+ iter_values = iter(values)
+ try:
+ previous_value = next(iter_values)
+ except StopIteration:
+ return
+ first = True
+ for value in iter_values:
+ yield first, False, previous_value
+ first = False
+ previous_value = value
+ yield first, True, previous_value
+'''
+syntax = Syntax(my_code, "python", theme="monokai", line_numbers=True)
+console = Console()
+console.print(syntax)
+```
+
+執行結果如下圖：
+
+
+
+
+
+
+Tracebacks（追溯）
+
+Rich 可以繪製 [漂亮的 tracebacks](https://rich.readthedocs.io/en/latest/traceback.html)，相較標準的 Python traceback 顯示了更多程式碼且更好懂。您可以將 Rich 設為預設的 traceback handler（處理常式），如此一來所有未接住的例外都由 Rich 呈現。
+
+它在 macOS 上執行的效果如圖（Linux 上差異不大）：
+
+
+
+
+
+所有可由 Rich 繪製的物件都用到了 [Console 協定](https://rich.readthedocs.io/en/latest/protocol.html)，您也可以依此實作自訂的 Rich 內容。
