ConTeXt：在 t-vim 代码块后分段落

Question

我将在这里编辑这个问题：

我希望能够\startc像那样工作$$math$$。

\starttext
In C, the program to print hello, world is
\startc
My C code here.
\stopc

Just how to run this program depends on the system you are using.

$$

\stoptext

我希望能够\inlinec像那样工作$math$。

\starttext
This means that every program must have a \inlinec{main} somewhere.

\inlinec{main} will usually call other

编辑前的问题：

想要在 t-vim 代码块后面添加一个新段落。我通过{\ \vskip -1\baselineskip}在代码块后面添加来实现这一点。但是它很脏。

在 ConTeXt 中执行此操作的正确方法是什么？

\parindent=20mm
\usemodule[vim]
\definevimtyping[c][margin=20mm]
\definevimtyping[sh][margin=20mm]
\starttext
In C, the program to print \quotation{\inlinesh{hello, world}} is
\startc
#include <stdio.h>

main()
{
    printf("hello, world\n");
}
\stopc%{\ \vskip -1\baselineskip}%the paragraph should break here, but..

Just how to run this program depends on the system you are using.
\stoptext

Answer 1

实现所需行为的正确方法是indentnext=auto。但是，模块中有一个错误，t-filter导致indentnext=auto无法正常工作。我上传了新版本t-filter（版本：2018.08.10），并修复了错误。

对于内联代码，您看到的是因为\inlinec发生在行首（如果{\bold Hello}发生在行首，您将看到相同的行为）。可以通过使用\dontleavehmode（或将left=\dontleavehmode）作为选项来修复此问题definevimtyping。我上传了新版本t-vim（ver：2018.08.10），并修复了此错误。

为了完整起见，我在下面保留了我的旧答案。

旧答案 正确答案是indentnext=auto，但由于回归错误，它不起作用。以下是适用于最小示例的快速修复。我将对其进行更多测试，然后发布t-filter包含修复的新版本：

\usemodule[vim]

% THIS IS THE BUGFIX:
\unprotect
\starttexdefinition externalfilter@process_filter
     % By defualt, buffers are in memory in MkIV. So, we save them to disk
     %
     %      \savebuffer[\externalfilter@buffer_name][\externalfilter@input_file]
     %
     % We can also save a list of buffers to a file. The empty
     % elements of the list are ignored. So, instead we use the following
     %
     %    \savebuffer[\externalfilterparameter{\c!buffer\c!before},
     %                \externalfilter@buffer_name,
     %                \externalfilterparameter{\c!buffer\c!after}]
     %               [\externalfilter@input_file]}
     %
     % but using this method we cannot save the file in another directory. 
     % So, we use the key-value interface for \savebuffer.
         \externalfilter@check_writable \externalfilter@input_file
         \savebuffer
           [
              \c!list={\externalfilterparameter{\c!buffer\c!before},
                       \externalfilter@buffer_name,
                       \externalfilterparameter{\c!buffer\c!after}},
              \c!file={\externalfilter@input_file},
              \c!prefix=\v!no,
            ]
     \externalfilter@execute_filter
     \externalfilter@read_processed_file
     \iftraceexternalfilters \else 
        \doif{\externalfilterparameter\c!purge}\v!yes
             {\ctxlua{os.remove(\!!bs\externalfilter@input_file\!!es)}}
     \fi
    \endgroup % Moved before \dorechecknextindentation

     % Finalization
     \doifinset{\externalfilterparameter\c!cache}{\v!yes,\v!force}
         {\doglobal\incrementvalue\externalfilter@count}

    \doif{\externalfilterparameter\c!location}\v!paragraph
        {\useindentnextparameter\externalfilterparameter
          \dorechecknextindentation}
\stoptexdefinition

\definevimtyping[c][syntax=c,margin=20mm, indentnext=auto]
\setupindenting[20mm,yes]
\setupformula[indentnext=auto]

\starttext

This means that every program must have a \inlinec{main} somewhere.

\dontleavehmode\inlinec{main} will usually call other

\stoptext

上述示例还展示了如何使用内联代码修复此问题。基本上，当您以 开始新段落时，\inlinec您需要在其前面加上\dontleavehmode。您可以通过添加 来自动执行此left=\dontleavehmode操作\definevimtyping。

还有另外一个错误： 之前有一个多余的空格\inlinec，上面的代码也修复了这个问题。

Answer 2

可以使用选项解决环境对缩进的抑制indentnext=yes。以下内容似乎可以满足您的要求：

\setupindenting[20mm,yes]

\usemodule[vim]

\definevimtyping[c][margin=20mm,indentnext=yes]
\usemodule[vim]

\definevimtyping[c][margin=20mm]
\definevimtyping[sh][margin=20mm]
\starttext

In C, the program to print \quotation{\inlinesh{hello, world}} is

\startc
#include <stdio.h>

main()
{
    printf("hello, world\n");
}
\stopc

Just how to run this program depends on the system you are using.
\stoptext

以供参考，这个问题似乎与缩进抑制有关。

更新：

评论中提到的$$...$$公式块让我认为问题不仅仅在于缩进，还在于块上方和下方的间距。可以使用spacebefore和spaceafter选项修改此间距：

\setupindenting[20mm,yes]

\usemodule[vim]

\definevimtyping[c]
  [margin=20mm,
   indentnext=yes,
   spacebefore=line,
   spaceafter=line]
\usemodule[vim]

\definevimtyping[c][margin=20mm]
\definevimtyping[sh][margin=20mm]
\starttext

In C, the program to print \quotation{\inlinesh{hello, world}} is

\startc
#include <stdio.h>

main()
{
    printf("hello, world\n");
}
\stopc

Just how to run this program depends on the system you are using.
