使用源代码“美化”投影仪演示文稿的资源？

我正在考虑使用 beamer 进行我即将进行的（幻灯片）演示，其中涉及大量源代码（幻灯片之间需要展开、修改、突出显示源代码片段等）。我之前看过 beamer 教程，但还没有真正用过。

我知道我可以使用 listings 或 minted 在幻灯片上排版代码片段，但坦率地说，结果有点丑陋。我希望包含代码的框看起来更“漂亮”、“更时尚”或“更精致”，如果你愿意的话：

  • 字体、线条和颜色与 beamer 主题相匹配（或许是补充）；
  • 关于矩形边距、圆角、阴影、透明度等设置的令人满意的组合。
  • 行号看起来不再像是事后才想到的；
  • 支持突出显示部分代码
  • 支持代码部分灰显

...或许还有其他养眼的东西。

某些主题或软件包中是否有类似的东西？如果没有，也许某些演示模板中也有？如果甚至都没有 - 也许某些具体的演示文档中也有，我可以对其进行调整？

PS-如果使用除投影仪之外的其他工具更容易实现这一点，请在评论中说明。

答案1

经过几天的研究，我终于找到了解决您大部分问题的可行方案。所以，请做好准备，因为它涉及很多技巧，而且看起来有点（太）长。解决方案涉及以下修改：

  • 重写LatexEmbeddedLexerinpygments以便它支持任何地方的转义（包括字符串和注释）和我们的自定义转义序列。
  • 重写LatexFormatter以便pygments动态生成样式并支持突出显示，灰化。

关于列表的外观

tcolorbox可以使用提供环境的软件包进行大量外观定制tcblisting。如软件包手册中所示，可以自定义列表块边框、背景颜色、边距样式、阴影、透明度等。调整参数以使其符合您喜欢的beamer主题非常容易。它还支持与 的集成minted，使用pygmentsPython 中强大的语法高亮器。总体而言，tcblisting与软件包相比，可以生成更高质量的代码列表listings。

对于一些具体问题，可以参考下面的链接：

添加高亮/灰显支持

在 的当前实现中minted，无法转义注释和字符串中的内容。转义序列也限制为一个字符长，这在实际中很不方便。可以使用以下文件 ( my_pygmentize.py) 修复此问题。它本质上与 相同pygmentize，但用LatexEmbeddedLexer我们自己的版本替换了 。在新实现 ( LatexExtendedEmbeddedLexer) 中，我们可以在函数中指定自己的转义序列__init__。在此示例中，我们使用了%* *)。该_find_safe_escape_tokens函数经过修改，以便我们可以在代码中的任何位置转义内容。

my_pygmentize.py

from pygments.token import Token
from pygments.lexer import Lexer, do_insertions
import pygments.formatters.latex as pygfmtlatex


class LatexExtendedEmbeddedLexer(pygfmtlatex.LatexEmbeddedLexer):
    def __init__(self, left, right, lang, **options):
        super().__init__('', '', lang, **options)
        
        # define left and right delimieters here
        self.left = '%*'
        self.right = '*)'

    # modified so that we can escape stuff in comments and strings
    def _find_safe_escape_tokens(self, text):
        for i, t, v in self._filter_to(
            self.lang.get_tokens_unprocessed(text),
            lambda t: False
        ):
            if t is None:
                for i2, t2, v2 in self._find_escape_tokens(v):
                    yield i + i2, t2, v2
            else:
                yield i, None, v


# replace LatexEmbeddedLexer
pygfmtlatex.LatexEmbeddedLexer = LatexExtendedEmbeddedLexer

# the rest is the same as pygmentize
import re
import sys
from pygments.cmdline import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

下一步是实现我们自己的支持高亮和灰化的格式化程序。与现有的不同LatexFormatter，我选择单独格式化每个字符，因为这样更容易实现背景颜色。但是，作为权衡，不支持边框。为了减少输出材料的空间，我决定根据样式在代码清单中的出现情况动态定义样式。

为了支持高亮/灰显，在格式化程序中添加了一个检查。我们可以使用特殊序列来切换高亮/灰显模式。例如，我曾经!!!切换高亮模式，并---切换灰显模式。可以在函数中更改每种模式的确切行为format_unencoded。

下一步，我们需要进行修改，minted以便它使用我们的词法分析器和格式化程序。这可以通过以下文件实现。我们将可执行文件从 更改为pygmentize；python3 my_pygmentize.py我们使用-x -f myformatter.py:LatexFormatter -P commandprefix=PY以便使用我们自己的格式化程序。此代码相当长，因为我必须复制粘贴 的定义\minted@pygmentize。不知何故\patchcmd无法使用它。
