How it works

For every file the following steps are performed:

1. Read file

The file is read from the filesystem and stored in memory.

> cat foobar.txt

The answer is ${{´40+2´}}
$[ifeq foo bar]$
Hello ${{foo}}$
$[else]$
Bye
$[end]$

2. Apply template

The commands will be evaluated and applied to the file.

> utpp --no-vars foobar.txt foo=bar

The answer is ${{´40+2´}}
Hello ${{foo}}$

3. Apply variables

The variables are applied to the template. The variables are a key-value pair that contains the values to replace in the template.

> utpp foobar.txt foo=bar

The answer is 42
Hello bar

4. Write file

The file is written to the filesystem or to the standard output depending on the cli arguments.
