考慮代碼：
\documentclass[12pt]{book}
\usepackage{microtype}
%\usepackage{ragged2e}
\begin{document}
\thispagestyle{empty}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\textbf{This is a minipage. The above line of commands justifies the text and centers the last line. Notice how "nice" it appears.}
\end{minipage}
\end{LARGE}
\end{center}
\vspace*{25pt}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\spaceskip1em plus 1em \xspaceskip 1em plus 2em\relax
\texttt{I have, with the two above lines of commands, been able to justify the tttext in this minipage, as well as center the last line of output. This is what I want; however, the appearance does not seem as "nice" as the content of the above minipage.}
\end{minipage}
\end{LARGE}
\end{center}
\end{document}
產生
儘管第二個小型頁產生了我正在尋找的東西——tttext左右對齊，最後一行輸出居中——與第一個小型頁的合理輸出相比，外觀似乎顯得蒼白。
我想透過調用ragged2e包；但這樣做後，除了將最後一行texttt文字居中之外，還使事情變得更糟。
問題：我如何（簡單地，如果可能的話）改進texttt文字對齊輸出的外觀（例如，減少行之間的間距，減少單字之間的間距——以減少輸出的行數）？
我用以下程式碼編譯程式碼lualatex
謝謝。

由於字間空間有彈性，因此沒有等寬字元對齊，因此最好使用可變寬度打字機字體，因為調整等寬字體總是看起來很糟糕。
lvmtt 預設允許連字符和可變的字間空間，因此需要的設定較少。
\documentclass[12pt]{book}
\usepackage{microtype}
%\usepackage{ragged2e}
\begin{document}
\thispagestyle{empty}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\textbf{This is a minipage. The above line of commands justifies the
text and centers the last line. Notice how "nice" it appears.}
\end{minipage}
\end{LARGE}
\end{center}
\vspace*{25pt}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\fontfamily{lmvtt}\selectfont
I
have, with the two above lines of commands, been able to justify
the tttext in this minipage, as well as center the last line of
output. This is what I want; however, the appearance does not seem
as "nice" as the content of the above minipage.
\end{minipage}
\end{LARGE}
\end{center}

今天沒有圖像，但是請參閱此處的輸出
答案2
根據上述評論，這是一種類似但不同的方法：
用\DeclareFontFamily{OT1}{cmtt}{\hyphenchar \font=1}在序言中。 （font=1 允許連字時使用破折號；font=-1 允許連字但不使用破折號。）
此外，減小字體大小也可以提高美觀性。
現在，程式碼
\documentclass[12pt]{book}
\usepackage{microtype}
\DeclareFontFamily{OT1}{cmtt}{\hyphenchar \font=1}
\begin{document}
\thispagestyle{empty}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\textbf{This is a minipage. The above line of commands justifies the text and centers the last line. Notice how "nice" it appears.}
\end{minipage}
\end{LARGE}
\end{center}
\vspace*{25pt}
\begin{center}
\begin{large}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\spaceskip1em plus 1em \xspaceskip 1em plus 2em\relax
\texttt{This is a minipage. The above line of commands justifies the text and centers the last line. Notice how "nice" it appears.}
\end{minipage}
\end{large}
\end{center}
\vspace*{25pt}
\begin{center}
\begin{large}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\spaceskip1em plus 1em \xspaceskip 1em plus 2em\relax
\texttt{This is a minipage. Supercalifragilisticexpialidocious Supercalifragilisticexpialidocious Supercalifragilisticexpialidocious Supercalifragilisticexpialidocious Supercalifragilisticexpialidocious}
\end{minipage}
\end{large}
\end{center}
\end{document}
產生輸出：
由於第二段中沒有任何內容可以連字符，因此我添加了第三段來說明代碼做產生連字符。
答案3
很難改進這樣的事情。等寬字體通常沒有字間拉伸性和收縮性，因為它們主要用於再現需要跨行字元對齊的文本，為了實現這一點，字間空間被設定為與字元一樣寬的嚴格長度。
此類字體通常不允許透過停用連字符來實現\hyphenchar。有了pdflatexOT1編碼的預設字體我們就可以閱讀ot1cmtt.fd看到
\ProvidesFile{ot1cmtt.fd}
[2019/12/16 v2.5j Standard LaTeX font definitions]
\DeclareFontFamily{OT1}{cmtt}{\hyphenchar \font\m@ne}
\DeclareFontShape{OT1}{cmtt}{m}{n}
{%
<5><6><7><8>cmtt8<9>cmtt9%
<10><10.95>cmtt10%
<12><14.4><17.28><20.74><24.88>cmtt12%
}{}
[...]
並\m@ne代表-1.大多數字體沒有\hyphenchar聲明，因為在這種情況下，TeX 將使用\defaulthyphenchar, 保存值 45（連字符的字體槽）。相反，字間空格的值儲存在檔案中.tfm，您可以透過操作適當的\fontdimen參數來變更它們。
相反lualatex，tulmtt.fd將使用：
\ProvidesFile{tulmtt.fd}
[2021/07/23 v1.8a Standard LaTeX font definitions for Latin Modern]
\DeclareFontFamily{TU}{lmtt}{%
\hyphenchar \font\m@ne
\fontdimen3\font\z@
\fontdimen4\font\z@
}
[...]
因此詞間空間的伸縮性被強制刪除。
但是，您應該記住，對字體參數的分配本質上是全局的：如果您計劃也將等寬字體用於逐字材料或列表，則需要在minipage.
我認為情況並非如此。
\documentclass[12pt]{book}
\usepackage{microtype}
\newenvironment{monospacedquote}{%
\begin{center}
\begin{minipage}{5.75in}
\LARGE
\ttfamily
\ifnum\hyphenchar\font=-1
\hyphenchar\font=`-
\fontdimen3\font=0.5\fontdimen2\font
\fontdimen4\font=0.3\fontdimen2\font
\fontdimen7\font=0.2\fontdimen2\font
\fi
\selectfont
\leftskip=\fill
\rightskip=-\leftskip
\parfillskip=\stretch{2}%
}{\end{minipage}\end{center}}
\begin{document}
\begin{monospacedquote}
This is a minipage. The above line of commands justifies the text
and centers the last line. Notice how awful it appears.
\end{monospacedquote}
\end{document}
答案4
你的問題是你透過設定在單字之間設定了很大的空格\spaceskip。我嘗試解釋你的問題：“我使用 TeX Primitive 設定了大空格\spaceskip，為什麼我有大空格？”
如果您設定的空格數量較少，\spaceskip那麼您將獲得所需的結果。此外，我為\tt字體設定了連字符，這在其他答案中也提到了。
\documentclass[12pt]{book}
\usepackage{microtype}
\begin{document}
\thispagestyle{empty}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
\textbf{This is a minipage. The above line of commands justifies the text and centers the last line. Notice how "nice" it appears.}
\end{minipage}
\end{LARGE}
\end{center}
\vspace*{25pt}
\begin{center}
\begin{LARGE}
\begin{minipage}{5.75in}\leftskip\fill\rightskip-\leftskip\parfillskip\stretch{2}%
%\spaceskip1em plus 1em \xspaceskip 1em plus 2em\relax %% ??? why this?
\spaceskip.3em plus .2em minus .1em \xspaceskip=\spaceskip {\tt\hyphenchar\font=`-}%
\texttt{I have, with the two above lines of commands, been able to justify the tttext in this minipage, as well as center the last line of output. This is what I want; however, the appearance does not seem as "nice" as the content of the above minipage.}
\end{minipage}
