打印在Windows批处理一个段落 [英] printing a paragraph in windows batch

问题描述

以下code工作pretty以及打印段落

The following code works pretty well printing the paragraph

@echo off
setlocal disableDelayedExpansion
set "skip="
for /f "delims=:" %%N in (
  'findstr /x /n ":::BeginText" "%~f0"'
) do if not defined skip set skip=%%N
>test.txt (
  for /f "skip=%skip% tokens=*" %%A in (
   'findstr /n "^" "%~f0"'
  ) do (
    set "line=%%A"
    setlocal enableDelayedExpansion
    echo(!line:*:=!
    endlocal
  )
)
type test.txt
exit /b

:::BeginText
This text will be exactly preserved with the following limitations:

  1) Each line will be terminated by CR LF even if original has only LF.

  2) Lines are limited in length to approximately 8191 bytes.

Special characters like ^ & < > | etc. do not cause a problem.
Empty lines are preserved!
;Lines beginning with ; are preserved.
:::Leading : are preserved

有没有一种方法来添加一个文本标记像 ::: ENDTEXT ，以便仅之间的段落
   ::: BeginText 和 ::: ENDTEXT 打印。

Is there a way to add a text marker like :::Endtext so that only the paragraph between :::BeginText and :::Endtext is printed.

推荐答案

当然： - ）

和您可以在脚本中嵌入多个命名的段落，有选择地采用了独特的标签，为他们每个人写的。

And you can embed multiple named paragraphs within your script and selectively write them by using a unique label for each.

命名的文本可以在任何地方的脚本中，只要被执行出现GOTO和/或EXIT / B prevent的文本。

The named text can appear anywhere within the script as long as GOTO and/or EXIT /B prevent the text from being executed.

下面的脚本封装在逻辑：printParagraph 常规方便

The script below encapsulates the logic in a :printParagraph routine for convenience.

@echo off
setlocal disableDelayedExpansion
goto :start

:::BeginText1
Paragraph 1
  is preserved

Bye!
:::EndText

:start
echo Print paragraph 1 directly to screen
echo ------------------------------------------
call :printParagraph 1
echo ------------------------------------------
echo(
echo(

call :printParagraph 2 >test.txt
echo Write paragraph 2 to a file and type file
echo ------------------------------------------
type test.txt
echo ------------------------------------------
echo(
echo(

echo Print paragraph 3 directly to screen
echo ------------------------------------------
call :printParagraph 3
echo ------------------------------------------
echo(
echo(

exit /b

:::BeginText2
This is paragraph 2

Pure poetry
:::EndText

:printParagraph
set "skip="
for /f "delims=:" %%N in (
  'findstr /x /n ":::BeginText%~1" "%~f0"'
) do if not defined skip set skip=%%N
set "end="
for /f "delims=:" %%N in (
  'findstr /x /n ":::EndText" "%~f0"'
) do if %%N gtr %skip% if not defined end set end=%%N
for /f "skip=%skip% tokens=*" %%A in (
 'findstr /n "^" "%~f0"'
) do (
  for /f "delims=:" %%N in ("%%A") do if %%N geq %end% exit /b
  set "line=%%A"
  setlocal enableDelayedExpansion
  echo(!line:*:=!
  endlocal
)
exit /b

:::BeginText3
One more...

  ...for good measure
:::EndText
