z3c.recipe.filetemplate 1.0

With the z3c.recipe.filetemplate buildout recipe you can automate the generation of text files from templates. Upon execution, the recipe will read a number of template files, perform a simple variable substitution and write the result to the corresponding output files.

For example, consider this simple template for a text file:

>>> write(sample_buildout, 'helloworld.txt.in',
... """
... Hello ${world}!
... """)

Now let’s create a buildout configuration so that we can substitute the values in this file. All we have to do is define a part that uses the z3c.recipe.filetemplate recipe. With the files parameter we specify one or more files that need substitution (separated by whitespace). Then we can add arbitrary parameters to the section. Those will be used to fill the variables in the template:

>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... parts = file
...
... [file]
... recipe = z3c.recipe.filetemplate
... files = helloworld.txt
... world = Philipp
... """)

After executing buildout, we can see that $world has indeed been replaced by Philipp:

>>> print system(buildout)
Installing file.

>>> cat(sample_buildout, 'helloworld.txt')
Hello Philipp!
