#### MAL (Meta Attack Language) to JSON encoding/decoding library and command-line tool.
Convert from MAL to JSON and, as of version 2, from JSON to MAL. Incompatible with the [official tool](https://github.com/mal-lang/mal2json).
## Info
**Author:** Victor Azzam
**License:** MIT
**Latest version:** `2.1.0`
**Requires:** Python 3.8 or later
**Batteries included:** Tests and examples are provided in this repository.
## Usage
### Install
```shell
~ pip install demal
```
### Or install from source
```shell
~ git clone https://github.com/victorazzam/demal
~ cd demal && pip install .
```
### Uninstall
```shell
~ pip uninstall demal
```
### General usage
### Convert `file.mal` to `file.mal.json`
```shell
~ demal file.mal
```
### Convert `file.mal` to `file.json`
```shell
~ demal file.mal file.json
```
### Convert `file.json` to `file.mal` (if JSON abides by [demal's output](#output))
```shell
~ demal file.json file.mal -r
```
### Convert `file.mal` and print it out
```shell
~ demal file.mal -
```
### Read from standard input, convert, and print it out
```shell
~ cat file.mal | demal - -
```
### Read from standard input, convert, and write to `out.json`
```shell
~ cat file.mal | demal - out.json
```
### Convert several files and view them interactively
```shell
~ cat file1.mal file2.mal | demal - - | less
```
### Display debugging information while converting
```shell
~ demal test2.mal debug
parse got: '#id: "tmp"'
parse got: '#version: "0.0.0"'
parse got: 'category C1 {'
parse_category got: '}'
parse got: 'category C2'
parse_header got: 'user info: "info"'
parse_header got: '{'
parse_category got: 'asset A1 {'
parse_asset got: '& At1'
parse_asset got: '| At2'
# output truncated
```
### Use it as a Python module
```py
from demal import MalParser
mal = MalParser('threat-model.mal')
mal.debug = True
mal.parse() # displays debugging messages due to the previous line
# output suppressed
mal.dump(out='parsed.json', pretty=True) # beautify and save to parsed.json
print(mal) # pretty-prints the json object
{
"associations": [
{
"asset_l": "Server",
"asset_l": "Client",
# output truncated
```
#### Merge multiple instances by addition (or multiplication or bitwise-or) akin to using `include`
Check `tests/test-lib.py`:
```py
from demal import MalParser
print('Parse and combine two test files.')
m1, m2 = MalParser('test1.mal'), MalParser('test2.mal')
m1.parse()
m2.parse()
print('First:', m1['version'])
# First: 1.0.0
print('Second:', m2['version'])
# Second: 0.0.0
m = m1 + m2 # combine category/association items, same as "include"
print('Combined:', m['version'])
# Combined: 0.0.0
print('\nModify variable.')
v = {'version': '1.3.3.7'}
m += v
print('New version:', m['version'])
# New version: 1.3.3.7
print('\nChange inner dictionary data.')
print('Before:', m['categories']['System']['assets']['Host']['attributes']['guessedPassword']['probability'])
# Before: Exponential(0.02)
m['categories']['System']['assets']['Host']['attributes']['guessedPassword']['probability'] = 'abc'
print('After:', m['categories']['System']['assets']['Host']['attributes']['guessedPassword']['probability'])
# After: abc
print('\nList assets with dot notation: category.asset')
print('m1:', list(m1))
print('m2:', list(m2))
print('m (m1+m2):', list(m))
# m1: ['System.Host', 'System.Network', 'System.Password', 'System.User']
# m2: ['C2.A1', 'C2.A2', 'C2.A3', 'C2.A4', 'C2.A5', 'C2.A6', 'C3.A1', 'C4.A1', 'C5.distribution']
# m (m1+m2): ['System.Host', 'System.Network', 'System.Password', 'System.User', 'C2.A1', 'C2.A2', 'C2.A3', 'C2.A4', 'C2.A5', 'C2.A6', 'C3.A1', 'C4.A1', 'C5.distribution']
print('\nConvert JSON back to MAL syntax.')
m.dump_mal(out = sys.stdout)
# Output redacted
```
## Output
Expect the following approximate output structure when converting to JSON:
```py
{
"associations": [
{
"asset_l": "left_asset",
"asset_r": "right_asset",
"field_l": "left_field",
"field_r": "right_field",
"meta": {
"key": "value"
# ...
},
"mult_l": "left_multiplier",
"mult_r": "right_multiplier",
"name": "Association"
} # ...
],
"categories": {
"Category1": {
"assets": {
"Asset1": {
"abstract": false,
"attributes": {
"access": {
"cia": ["C", "A"],
"meta": {},
"probability": "Exponential(0.02)", # etc, or simply null
"tags": [],
"type": "and"
},
"authenticate": {
"cia": null,
"leads_to": {
"0": "access",
"a": "b \\/ c " # result of: let a = ...
},
"meta": {},
"probability": null,
"tags": [
"hidden",
"debug",
"trace"
],
"type": "or"
} # ...
},
"extends": null,
"meta": {}
} # ...
},
"meta": {}
}
},
"id": "org.name.project",
"version": "1.0.0"
}
```
When converting to MAL the output should closely resemble the original, albeit more concise.
## Limitations
- [X] ~Multi-line comments should be avoided.~
- [ ] Quotation marks must not be escaped.
