About

pip install toml-union

This PyPI package is indeed located in one script and combines several *.toml files (usially pyproject.toml) into one. If it finds some conflicts between items, they will be kept for manual review.

It has a docker image (docker pull pasaopasen/toml-union) and an example of its usage.

Python usage example

from pathlib import Path

from toml_union import toml_union_process

# run union
toml_union_process(
    files=Path('input').glob('*.toml'),   # get all *.toml files from examples dir
    outfile='output.toml',  # set output file path
    report='report.json',   # path for conflicts report on conflict case
)

It combines next files:

[tool.poetry]
name = "project 1"
version = "1.6.0"
description = "Some words"
authors = ["Me"]

[tool.poetry.dependencies]
"pdfminer.six" = "^20220524"

[build-system]
requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"

to this one:

[build-system]
build-backend = [ "poetry.core.masonry.api", "poetry.masonry.api",]
requires = [ "poetry-core>=1.0.0", "poetry>=0.12",]

[tool.poetry]

version = "1.10.1+cu113"

pytest-django = "^4.5.2"

As u see, some packages have confict versions. In this case the report file is created and contains the sources of this conflicts:

"pdfminer.six": {
    "^20220524": [
    "input/file1.toml",
    "input/file3.toml"
    ],
    "^2022333333334": [
    "input/file2.toml"
    ]
},
"cmake": {
    "^3.21.1": [
    "input/file1.toml"
    ],
    "~3.21.1": [
    "input/file3.toml"
    ]
},
"other_package": {
    "1": [
    "input/file1.toml"
    ],
    "2": [
    "input/file2.toml"
    ]
}

Overrides

There is the ability to override some items in target *.toml file. Use syntax:

toml_union_process(
    files=Path('input').glob('*.toml'),
    outfile='output.toml',
    report='report.json',

    overrides={
        'tool.poetry.name': 'union',
        'tool.poetry.version': '12'
    }
)

In the result u will have:

[tool.poetry]
name = "union"
version = "12"

CLI

Equivalent CLI command:

toml-union examples/input/file1.toml examples/input/file2.toml examples/input/file3.toml -o output.toml -r report.json -k tool.poetry.name=union -k tool.poetry.version=12

Help message:

toml-union -h

usage: toml_union.py [-h] [--output OUTFILE] [--unicode-escape] [--report REPORT] [--remove-field [REMOVE_FIELDS [REMOVE_FIELDS ...]]] [--key-value KEY=VALUE] [--ckey-value KEY=VALUE] INPUT [INPUT ...]

Combines several toml files to one with conflicts showing

positional arguments:
  INPUT                 input toml files paths

optional arguments:
  -h, --help            show this help message and exit
  --output OUTFILE, -o OUTFILE
                        output toml file path, empty value means to print to console (default: None)
  --unicode-escape, -u  whether to try to escape unicode sequences in the outfile, useful when outfile has many slashes and codes (default: False)
  --report REPORT, -r REPORT
                        path to report json on failure (default: None)
  --remove-field [REMOVE_FIELDS [REMOVE_FIELDS ...]], -e [REMOVE_FIELDS [REMOVE_FIELDS ...]]
                        Fields to remove. May appear multiple times (default: None)
  --key-value KEY=VALUE, -k KEY=VALUE
                        Add key/value params. May appear multiple times (default: {})
  --ckey-value KEY=VALUE, -c KEY=VALUE
                        Same as --key-value but will be performed only on conflict cases (default: {})
