replacer.exe simply replaces a given string for another given string in a given file. The file is overwritten by the new derivate.

replacer.exe is written in C#, namely, this line:

File.WriteAllText (args[0], File.ReadAllText (args[0]).Replace (args[1], args[2]));

(Warning: make sure the program has not been upgraded by the time you are reading this.)

We use replacer.exe for upgrading project files and Web.config after copying new assemblies to our PhoneBook project.

Usage

In the C:\PhoneBook-SVN\tools subdirectory (or wherever), incant this:

replacer\replacer\bin\Debug\replacer.exe C:\PhoneBook-SVN\PhoneBook.Web\Web.config 1.13.6.2 1.13.13.2

This will overwrite the Web.config file with a new derivative, containing no more "1.13.6.2" strings, because they were all replaced by "1.13.13.2".

We have prepared a file in the dummy sub-directory for you to play with:

C:\PhoneBook-SVN\tools>type dummy\replacer-test.txt
On today's menu we have Spam, Spam, Spam, Spam, Spam, baked beans, Spam, Spam, Spam and Spam.

C:\PhoneBook-SVN\tools>replacer\replacer\bin\debug\replacer.exe dummy\replacer-test.txt Spam HAM

C:\PhoneBook-SVN\tools>type dummy\replacer-test.txt
On today's menu we have HAM, HAM, HAM, HAM, HAM, baked beans, HAM, HAM, HAM and HAM.

REM BE A GOOD CITIZEN, RESTORE THE ORIGINAL TEST FILE
C:\PhoneBook-SVN\tools>copy dummy\replacer-test-orig.txt dummy\replacer-test.txt
Overwrite dummy\replacer-test.txt? (Yes/No/All): y
        1 file(s) copied.
Room for improvement

replacer.exe should report an error if no strings can be found for substitution
