使用 -t 选项后跟格式而不是带有扩展名的文件，例如 pandoc -f json -t markdown 将输出该 markdown，-t html 将输出 html 等以捕获输出使用重定向运算符操作 > file.some_extension 。但你的输出将发送到控制台。所以正确的语法实际上是 pandoc -f json -t markdown。
Also the pandoc documentation http://pandoc.org/README.html.
If you run into problems try to modify your lune from:
pandoc -o temp.html --filter .\tikz.bat -s temp.md ==> pandoc -t json | ./caps.py latex | pandoc -f json -t html.
这就是它的工作原理。
source format = input_file.html
↓
(pandoc) = pandoc -t json input_file.html
↓
JSON-formatted AST
↓
(filter) = python $HOME/Downloads/pandocfilters-1.2.4/examples/caps.py
↓
JSON-formatted AST
↓
(pandoc) = pandoc -f json -t markdown
↓
target format = output_file.md
分隔命令以检查输出并使用管道 |重定向输出：
pandoc -t json ~/testing/testing.html | python examples/caps.py | pandoc -f json -t markdown > output_file.md
无需安装 pandocfilters 下载 tar 文件，运行 tar -xvf file.x.y.z 或使用任何其他选择的应用程序，并参考调用 python dir/to/script.py 的示例，然后再次将输出通过管道传输到 pandoc 并将输出重定向到所需的文件格式。这是逐行的：
$pandoc -t json ~/testing/testing.html
[{"unMeta":{"viewport":{"t":"MetaInlines","c":[{"t":"Str","c":"width=device-width,"},{"t":"Space","c":[]},{"t":"Str","c":"initial-scale=1"}]},"title":{"t":"MetaInlines","c":[]},"description":{"t":"MetaInlines","c":[]}}},[{"t":"Para","c":[{"t":"Str","c":"Hello"},{"t":"Space","c":[]},{"t":"Str","c":"world!"},{"t":"Space","c":[]},{"t":"Str","c":"This"},{"t":"Space","c":[]},{"t":"Str","c":"is"},{"t":"Space","c":[]},{"t":"Str","c":"HTML5"},{"t":"Space","c":[]},{"t":"Str","c":"Boilerplate."}]},{"t":"Para","c":[{"t":"Str","c":"l"}]}]]
then:
$pandoc -t json ~/testing/testing.html | python examples/caps.py
[{"unMeta": {"description": {"c": [], "t": "MetaInlines"}, "viewport": {"c": [{"c": "WIDTH=DEVICE-WIDTH,", "t": "Str"}, {"c": [], "t": "Space"}, {"c": "INITIAL-SCALE=1", "t": "Str"}], "t": "MetaInlines"}, "title": {"c": [], "t": "MetaInlines"}}}, [{"c": [{"c": "HELLO", "t": "Str"}, {"c": [], "t": "Space"}, {"c": "WORLD!", "t": "Str"}, {"c": [], "t": "Space"}, {"c": "THIS", "t": "Str"}, {"c": [], "t": "Space"}, {"c": "IS", "t": "Str"}, {"c": [], "t": "Space"}, {"c": "HTML5", "t": "Str"}, {"c": [], "t": "Space"}, {"c": "BOILERPLATE.", "t": "Str"}], "t": "Para"}, {"c": [{"c": "L", "t": "Str"}], "t": "Para"}]]
finally:
pandoc -t json ~/testing/testing.html | python examples/caps.py | pandoc -f json -t markdown
HELLO WORLD! THIS IS HTML5 BOILERPLATE.
