Single file templater

Project Description

sftmpl takes a single file as input and uses the built-in string format method to replace the occurences of brace-enclosed variables by values given on the command-line.

The aim of sftmpl is to simplify the generation of configuration file in computing protocols by providing a command-line enabled customization of these configuration files.


Obtain the distribution file and use

python install

The source repository is and the code may be obtained via the command

git clone


sftmpl uses the curly brace named fields defined in PEP 3101.

For the following input file myconfig.txt, you must provide the command-line options -N, –parameter and –N_steps:

# Config for "myprog"
N = {N}
parameter = {parameter}

run {N_steps} steps

The invocation is as follows when sftmpl is installed

sftmpl myconfig.txt -N 10 –parameter 0.1 –N_steps 500

and the following result is output to the standard output:

# Config for "myprog"
N = 10
parameter = 0.1

run 500 steps
