secsie-conf 2.1.0

A small library for parsing configuration files

secsie-conf

pip3 install secsie-conf

Secsie is a configuration language parser for Python, made for speed and beauty. Instead of writing config files in JSON (don't get me wrong, JSON is FAR better than a lot of other things you could use (cough cough XML)), you can save time writing your config files in secsie.
The secsie language format is very similar to ini, except just a little better. You can use secsie-conf to read .ini files into Python dicts. secsie-conf will NOT write .ini files however, at least at this stage.

Advantages over JSON:

• easier to read
• faster to write
• no special syntax required for strings vs ints, floats, bools, etc.

Secsie Language Contructs

These are the rules of the secsie config language:

1. Comment lines begin with # or ;, but inline comments can only begin with the octothorpe (#).
2. Whitespace is ignored everywhere except in key names and section tag names.
3. A config file consists of sections and attributes(keys and values).
4. A section ends where the next section begins. Attributes declared before sections are valid.
5. To begin a section use the following syntax:

[section1]
# attribute lines in this section follow

6. The syntax for an attribute line is:

key = value

7. Spaces are not allowed in key names or section tags. Only a-z(case insensitive), 0-9, _, and - are allowed in section tag names, while other special characters are allowed in key names.
8. Values can consist of any character except #. Leading and trailing whitespace is removed.

INI

secsie-conf can be used to read .ini files, as long as the mode ini is specifed to the parser. The rules of interpretation for .ini files vary slightly.

Differences:

• Section names are allowed to contain spaces and dashes
• quoted strings are valid, but the quotes are removed (there is no need to quote string in secsie ;)
  secsie-conf can NOT be used to write .ini files. You can read an .ini file and output it in valid secsie, but you cannot expect valid .ini output.

Valid values

Secsie supports strings, ints, floats, null types, and booleans. All of these types can be written out by themselves and will automatically be converted to the appropriate native type.

Strings:

# Spaces are allowed in string value
string_key = whatever value you want

Ints:

numb = 42  # Automatically converted to int when parsed

Floats:

pi = 3.14159265  # Automatically converted to float when parsed

Booleans:

# True and yes are truthy values (case insensitive)
truth = true
truth2 = True
truth3 = yes
# False and no are falsy values (case insensitive)
untruth = falsE
untruth2 = False
untruth3 = no

Null type (None):

# 'null' is used as the NoneType (case insensitive)
nothing = null

Examples

examples/valid.secsie.conf:

; This is an example of a valid secsie file

before_section = totally okay

# Whitespace don't matter

; Here are examples of how types are interpreted(no keywords are off limits!)
[special_values]
    int = 42
    float = 269.887
    truth = yes
    falsehood = no
    true = true
    ; I don't encourage this but it's valid ;)
    false = FaLSe

    # Null value
    nah = Null

[anotherSection]
    # The indent here is optional, included for readability
    sections = are amazing

Parse result:

{'before_section': 'totally okay', 'special_values': {'int': 42, 'float': 269.887, 'truth': True, 'falsehood': False, 'true': True, 'false': False, 'nah': None}, 'anotherSection': {'sections': 'are amazing'}}

Module Usage

Read a secsie config file as a dict:

import json
import secsie

# To get a dict from a config file
config = secsie.parse_config_file('examples/valid.secsie.conf')
print(json.dumps(config, indent=2))  # For prettyness

Result:

{
  "before_section": "totally okay",
  "special_values": {
    "int": 42,
    "float": 269.887,
    "truth": true,
    "falsehood": false,
    "true": true,
    "false": false,
    "nah": null
  },
  "anotherSection": {
    "sections": "are amazing"
  }
}

Read an .ini file:

import json
import secsie

# This might not work...
config = secsie.parse_config_file('examples/php.ini')

Result:

...Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/nbroyles/PycharmProjects/secsie-conf/secsie/__init__.py", line 109, in parse_config_file
    conf = _write_to_conf_(conf, line, line_number=lineno, section=c_section, mode=mode)
  File "/home/nbroyles/PycharmProjects/secsie-conf/secsie/__init__.py", line 63, in _write_to_conf_
    raise InvalidSyntax(f'Syntax Error on line {line_number}: "{line}" bad section descriptor or value assignment')
secsie.InvalidSyntax: Syntax Error on line 955: "[CLI Server]" bad section descriptor or value assignment

We can see that this up and broke. Dub tee eff?! Actually, its okay. Spaces aren't allowed in secsie section names, remember? When reading an .ini file, we need to pass the argument mode='ini' to the parse_config_file function, like this:

config = secsie.parse_config_file('examples/php.ini', mode='ini')
print(json.dumps(config, indent=2))

That ^'s a whole PHP configuration file converted to some sexy secsie JSON!

Write a secsie file:

Now that we have the php.ini contents stored in config, let's output it in secsie!

secsie.generate_config_file(config, output_file='examples/php_ini.secsie.conf')

Output (examples/php_ini.secsie.conf):

You should notice 2 things:

1. Keys and value assignments are separated by an equals sign with a space ON BOTH SIDES! key = value, NOT key=value. That is ugly and lazy. This ain't minified JS, son. They make things for that...
2. Blank values were commented out. If you disagree with that, MAKE 'EM NULL! key = doesn't say anything.
