Generate config file from template using Python search and replace.
I need to generate a config file based on an existing "template" file. I need
to replace a set of strings with other strings globally in the generated file.
Here is a snippet of the template file, where CONTENT_PATH and DAMPATH are two
"placeholders" or variables. There are several other such placeholders.
$include "_dispatcher_publish_filters.any"
/1000 { /type "allow" /glob "* /CONTENT_PATH/*.html*" }
/1001 { /type "allow" /glob "POST /DAMPATH/www/*.html *" }
The script's user will be asked to type in unique values when prompted for
DAMPATH or CONTENT_PATH.
Since I know the variables themselves are not going to change (because the
contents of the template file don't spontaneously change) should I be using
regex to search for them or is there a better way? I was planning on using
re.sub but I don't know whether that's the best way. Here's what my script
looks like today.
from sys import argv
import re
from os.path import exists
script, template_file = argv
print "Opening the template file..."
in_file = open(template_file)
lines = in_file.readlines()
print "What is the serial number of the site?",
_NNN = raw_input()
print "What is the brand, or product name?",
_BRAND = raw_input()
print "What is the content path?",
_CONTENT_PATH = raw_input()
out_file = open(_nnn + _brand + "_farm.any", 'w')
for line in lines:
re.sub('NNN', _NNN, line)
re.sub('BRAND, _BRAND', line)
re.sub('CONTENT_PATH', _CONTENT_PATH, line)
out_file.close()

I should mention the template file is small, just 98 lines long and the working config file will be the same size. -- https://mail.python.org/mailman/listinfo/python-list

I can't understand re.sub
I need to use re.sub to replace strings in a text file. I can't seem to understand how to use the re module to this end. result = re.sub(pattern, repl, string, count=0, flags=0); I think I understand that pattern is the regex I'm searching for and repl is the thing I want to substitute for whatever pattern finds but what is string? The items I'm searching for are few and they do not change. They are "CONTENT_PATH", "ENV" and "NNN". These appear on a few lines in a template file. They do not appear together on any line and they only appear once on each line. This should be simple, right? -- https://mail.python.org/mailman/listinfo/python-list

Thanks. That does help quite a lot. -- https://mail.python.org/mailman/listinfo/python-list

I rarely get a chance to do any scripting so yeah, I stink at it. Ideally I would have a script that will spit out a config file such as 087_pre-prod_snakeoil_farm.any and not need to manually rename said output file. -- https://mail.python.org/mailman/listinfo/python-list

I seem to be heading in this direction.
#!/usr/bin/env python
import re
from os.path import exists
script, template_file = argv
print "Opening the template file..."
with open (template_file, "r") as a_string:
data=a_string.read().replace('BRAND', 'Fluxotine')
print(data)
So now the challenge is to use the read().replace magic for multiple values.

Yup, I sure did. So here is my current script. The only remaining task now is
figuring out how to write the contents to a new file.
#!/usr/bin/env python
import os
import sys
script, template_file = sys.argv
print "Opening the template file..."
print "What is the serial number of the site?",
nnn = raw_input()
print "What is the brand, or product name?",
brand = raw_input()
print "What is the (fqdn) ServerName?",
server_name = raw_input()
print "What is the content path?",
content_path = raw_input()
print "What is the DAM path?",
dampath = raw_input()
print "Which environment is this for?",
env = raw_input()
print "What is the cache document root?",
cache_docroot = raw_input()
with open (template_file, "r") as a_string:
data=a_string.read().replace('{SERVER_NAME}',
server_name).replace('{BRAND}', brand).replace('{CONTENT_PATH}',
content_path).replace('{DAMPATH}', dampath).replace('{ENV}',
env).replace('{CACHE_DOCROOT}', cache_docroot)

Oh, that's much easier to read. Thanks! -- https://mail.python.org/mailman/listinfo/python-list
Re: Generate config file from template using Python search and replace.
Actually, I don't understand what you mean by "all other braces." What braces are you talking about? The placeholders in the template file (the file being read in) have braces around them but they are not escaped. Also, do I really need curly braces to tell Python what my placeholders are? -- https://mail.python.org/mailman/listinfo/python-list
Re: Generate config file from template using Python search and replace.
That makes sense. So I still can't see how to write the string object to a file whist naming the file with whatever values I provided for the NNN and BRAND variables. Printing the contents of the string object is working with all the expected substitutions. Do I need to convert the string object into a file before I write it? Or do I need to open a new file and somehow stuff the string object into it? -- https://mail.python.org/mailman/listinfo/python-list
Re: Generate config file from template using Python search and replace.
Ye, this does work. Many thanks!
filename = "{NNN}_{BRAND}_farm.any".format(BRAND=brand, NNN=nnn)
with open(filename, "w") as outstream:
outstream.write(data)
