Question

Based on this thread. I’ve tried to replace the set the current version of my project in my NAnt script.

Here’s my Replace snippet

<target name="Replace">
    <loadfile file="${SetVersionCpp.File}" property="h.file.content" />
    <regex
      input="${h.file.content}"
      pattern="(?'BEFORE'[.\s]*)${LineBegining}\s*[\s\d,]*\r\n(?'AFTER'[.\s]*)" />
    <echo
      file="${SetVersionCpp.File}"
      message="${BEFORE}${LineBegining} ${ReplaceWith}
      ${AFTER}"
      append="false"
      verbose="true" />
</target>

Which I call on this file

#define FILEVER 0, 2, 0, 3
#define PRODUCTVER 0, 2, 0, 3
#define STRFILEVER     "00.02.00.03\0"
#define STRPRODUCTVER  "00.02.00.03\0"

with the following parameters

<property name="SetVersionCpp.File" value="${baseline.dir}\VersionNo.h" />
<property name="LineBegining" value="#define FILEVER" />
<property name="ReplaceWith" value="${FileVersion}" />

Based on the output, the AFTER variable is not capturing the rest of the file for some reason. This is what I get:

[#define FILEVER 0, 2, 0, 30

]

*I put it in brackets so that the whitespace got correctly formatted

Any ideas what I’m doing wrong?

I’ve fixed it by setting the options to Singleline so that . would match line breaks and by removing the classes from the groups:

<regex
  input="${h.file.content}"
  options="Singleline"
  pattern="(?'BEFORE'.*)${LineBegining}\s*[\s\d,]*\r\n(?'AFTER'.*)" />
