Question

好的，我有一个变量，用于设置语句%nl%以创建多行声明，在多行语句中是变量%resultA% 我希望整个语句（包含其中的变量）在另一个变量中。

例如〜我想要

set nl=^& echo.

echo ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ»%nl%º  Player (Caesar)      º%nl%º         ^|              º%nl%º  Health ^| ÉÍÍÍÍÍÍÍ»   º%nl%º         ^| º%resultA%º   º%nl%º         ^| ÈÍÍÍÍÍÍÍ¼   º%nl%ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ¼%nl%

看起来像

set nl=^& echo.

set MyVar="echo ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ»%nl%º  Player (Caesar)      º%nl%º         ^|             º%nl%º  Health ^| ÉÍÍÍÍÍÍÍ»   º%nl%º         ^| º%resultA%º   º%nl%º         ^| ÈÍÍÍÍÍÍÍ¼   º%nl%ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ¼%nl%"

每当我在批处理文件中回调变量时，我都会收到错误说明ECHO IS OFF，当然我已经知道了这一点，但我试图将多行替换为一个变量（其中包含另一个变量），而echo则关闭...

尝试到处寻找无济于事。有线索吗？

// Template file #include <dir/Test1.h> #include <dir/Test2.h> #include <dir/Test3.h> void function(); library(data.table) date <- as.POSIXct('2015-01-01 14:30:00') # appointments data table app <- data.table(med.id = 1:10, filial.id = rep(c(100,200), each = 5), start.time = rep(seq(date, length.out = 5, by = "hours"),2), end.time = rep(seq(date+3599, length.out = 5, by = "hours"),2), A = rnorm(10)) # receptions data table re <- data.table(med.id = c(1,11,3,4,15,6,7), filial.id = c(rep(100, 5), 200,200), start.time = as.POSIXct(paste(rep('2015-01-01 ',7), c('14:25:00', '14:25:00','16:32:00', '17:25:00', '16:10:00', '15:35:00','15:50:00'))), end.time = as.POSIXct(paste(rep('2015-01-01 ',7), c('15:25:00', '15:20:00','17:36:00', '18:40:00', '16:10:00', '15:49:00','16:12:00'))), B = rnorm(7)) app$count <- 0 for (i in 1:dim(app)[1]){ for (j in 1:dim(re)[1]){ if ((app$med.id[i] == re$med.id[j]) & # med.id is equal and app$filial.id[i] == re$filial.id[j]) { # filial.id is equal if ((re$start.time[j] < app$start.time[i]) & (re$end.time[j] > app$start.time[i])) { # reception starts before appointment start time and ends after appointment start time OR app$count[i] <- app$count[i] + 1 } else if ((re$start.time[j] < app$end.time[i]) & (re$start.time[j] > app$start.time[i])) { # reception starts before appointment end time and after app. start time app$count[i] <- app$count[i] + 1 } } } }后的所有内容都会立即进入包含=的变量。

而是在变量之前移动开头引号：

set var=

问题在于set nl=^&echo.没有创建新的线条字符，而是将回声分成多个部分并独立回显每个部分，但它根本不是很稳定。

最好使用一个真正的新行字符

setlocal EnableDelayedExpansion
(set nl=^
%=DONT_CHANGE_THIS_LINE=%
)
echo ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ»!NL!º  Player (Caesar)      º!nl!º         ^|             º!nl!º  Health ^| ÉÍÍÍÍÍÍÍ»   º!nl!º         ^| º%resultA%º   º!nl!º         ^| ÈÍÍÍÍÍÍÍ¼   º!nl!ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ¼!nl!

此换行符只能用于延迟扩展！

包含多个ECHO语句的变量（通过％nl％变量）无法正确扩展
