Replacer

The Replacer node type will help you replace the content of a file on disk.

(1) This node has been set to the "Replacer" node type.

These are the parameters you can pass:

(2) file - This is the file's name whose contents need to be replaced. This should not be hard coded, rather, it should be written in a way that will make it to be constructed from Expanders. For example:

A string like this: [%EF_SCAFFOLD_FOLDER%]\[%DB_CONTEXT%].cs

can expand into C:\codestencil\generated\ef-scaffold-folder\MyProjectContext.cs

(3) replacementText - This is the text you will use to replace the targetText. It can also consist of expanders, e.g.

{ [%CARRIAGE_RETURN%]    public [%DB_CONTEXT%]() {} [%CARRIAGE_RETURN%]

Which may expand into something like this: 

(4) targetText - This is the text you want to replace/overwrite. In this case, we want to replace the first "{"

(5) targetTextStringCheck—The replacer algorithm will check if this string exists. If so, it aborts the replace function. This may be needed in cases where the string has already been replaced in a prior cycle, and running the replacer again may mess up the source/target file. Most of the time, this string will be exactly the same string used for the replacement text.

 

When combined, it may look like this:
