想要一个AWK实现“@include” [英] Want an AWK that implements '@include'

问题描述

在gawk的手册我把它描述了一个 @include 运营商。这可让您.awk模块和共享脚本等包含文件。

In the gawk manual I have it describes an @include operator. This lets you make .awk modules and share scripts, etc. Include files.

到目前为止最新的cgywin，MinGW和GNU AWK-S（AWK，GAWK，mawk，NAWK，...）我已经找到了失败的Windows上的第一个： @include 语句。

So far the latest cgywin, mingw and gnu awk-s (awk, gawk, mawk, nawk, ...) I've found for Windows fail on the first: @include statement.

有人点我到实现的Windows全NAWK和awk实现一个版本？我是pretty确保有至少有一个NAWK，早在一天，我们已经下载到运行Windows NT的。

Can someone point me to a version that implements the whole nawk or awk implementation for Windows? I am pretty sure there was at least one nawk, back in the day, that we had downloaded to run Windows NT.

另外一种解决方法是在此期间有帮助的。 （说一个pre-测试AWK includer程序？）

Alternately a work around would be helpful in the meantime. (Say a pre-tested awk includer program??)

的 TIA 的，
     请问

推荐答案

据我所知， @include 文件本身不支持GAWK直到4.x版。然而，至少在Linux上，它附带一个名为shell脚本 igawk ，您可以使用替代;它preprocesses awk脚本，并替换 @include s的包含文件（通过 $ AWKPATH 中的内容）。也许Cygwin的也有这个脚本？

As far as I can tell, @include files are not supported natively by gawk until 4.x. However, at least on Linux, it ships with a shell script called igawk that you can use instead; it preprocesses awk scripts and replaces @includes with the contents of the included file (found via $AWKPATH). Perhaps Cygwin also has this script?

$ cat foo.awk
@include bar.awk
$ cat bar.awk
BEGIN {print "Hello, world!" }
$ awk -f foo.awk
awk: foo.awk:1: @include bar.awk
awk: foo.awk:1: ^ invalid char '@' in expression
$ gawk -f foo.awk
gawk: foo.awk:1: @include bar.awk
gawk: foo.awk:1: ^ invalid char '@' in expression
$ igawk -f foo.awk
Hello, world!

请注意，但是， igawk 和呆子4的 @include 语法不兼容。在GAWK 4本机 @include 要求对文件名包含带引号的字符串; igawk 的需要裸词，并会尝试找到其名称中引号的文件，如果你引用它。

Note, however, that igawk and gawk 4's @include syntaxes are not compatible. The native @include in gawk 4 requires a quoted string for the included filename; igawk's takes a bareword, and will try to find a file with quotation marks in its name if you quote it.
