## Installation
```bash
pip install changelog2version
```
## Usage
This example shows you how to parse the [repo's changelog](changelog.md) and
update the [package version file][ref-package-version-file] with that
version.
```bash
changelog2version \
--changelog_file changelog.md \
--version_file examples/version.py \
--debug
```
### Available default template files
By default a Python version file is generated. Check the table below and the
example usage for further details and supported template files
| Type | Parameter | Description |
| ------ | --------- | ----------- |
| Python | `py` | See [example package version][ref-package-version-file] |
| C/CPP | `c` | Header file with available version info |
#### C header file
```bash
changelog2version \
--changelog_file changelog.md \
--version_file examples/version_info.h \
--version_file_type c \
--debug
```
```
//
// version_info.h
//
// Created automatically by script
//
#ifndef version_info_h
#define version_info_h
#define MAJOR_VERSION 0 //< major software version
#define MINOR_VERSION 4 //< minor software version
#define PATCH_VERSION 0 //< patch software version
#endif
```
#### Python package file
```bash
changelog2version \
--changelog_file changelog.md \
--version_file examples/version.py \
--version_file_type py \
--debug
```
```
#!/usr/bin/env python3
# -*- coding: UTF-8 -*-
__version_info__ = ("0", "4", "0")
__version__ = '.'.join(__version_info__)
```
#### JSON output
The additional, optional argument `--pretty` will output the JSON data with an
indentation of 4 in order to provide the data in an easy to read format.
##### Console
```bash
changelog2version \
--changelog_file changelog.md \
--print \
--debug
```
```json
{"info": {"version": "0.7.0", "description": "### Added\n- Changelog parsed as JSON contains a new key `description` like the PyPi package JSON info, compare to `https://pypi.org/pypi/changelog2version/json`, with the description/content of the latest change, see #19, relates to #18\n- Increase unittest coverage above 95%\n\n### Changed\n- Line breaks are no longer used in this changelog for enumerations\n- Issues are referenced as `#123` instead of `[#123][ref-issue-123]` to avoid explicit references at the bottom or some other location in the file\n- Output of `changelog2version` call with `--print` but without `--debug` option is JSON compatible\n"}, "releases": {"0.7.0": [{"upload_time": "2022-11-11"}], "0.6.0": [{"upload_time": "2022-10-26"}], "0.5.0": [{"upload_time": "2022-10-20"}], "0.4.0": [{"upload_time": "2022-08-07"}], "0.3.0": [{"upload_time": "2022-08-05"}], "0.2.0": [{"upload_time": "2022-08-03"}], "0.1.1": [{"upload_time": "2022-07-31"}], "0.1.0": [{"upload_time": "2022-07-31"}]}}
```
To get the latest version and description in the console as environment
variables use the following call
```bash
LATEST_VERSION=$(changelog2version --changelog_file changelog.md --print | python -c "import sys, json; print(json.load(sys.stdin)['info']['version'])")
LATEST_CHANGE=$(changelog2version --changelog_file changelog.md --print | python -c "import sys, json; print(json.load(sys.stdin)['info']['description'])")
echo "The latest version extracted from the changelog is ${LATEST_VERSION}"
# The latest version extracted from the changelog is 0.7.0
echo "Description of the latest change"
echo "${LATEST_CHANGE}"
# ### Added
# - Changelog parsed as JSON contains a new key `description` like the PyPi package JSON info, compare to `https://pyp
# i.org/pypi/changelog2version/json`, with the description/content of the latest change, see #19, relates to #18
# - Increase unittest coverage above 95%
# ### Changed
# - Line breaks are no longer used in this changelog for enumerations
# - Issues are referenced as `#123` instead of `[#123][ref-issue-123]` to avoid explicit references at the bottom or s
# ome other location in the file
# - Output of `changelog2version` call with `--print` but without `--debug` option is JSON compatible
```
##### File
```bash
changelog2version \
--changelog_file changelog.md \
--output changelog.json \
--pretty \
--debug
```
See [example JSON file][ref-example-json-file]
## Advanced
### Custom regular expressions
To extract a version line from a given changelog file with an alternative
regex, the `version_line_regex` argument can be used as shown below. The
expression is validated during the CLI argument parsing
```bash
changelog2version \
--changelog_file changelog.md \
--version_file src/changelog2version/version.py \
--version_line_regex "^\#\# \[\d{1,}[.]\d{1,}[.]\d{1,}\]" \
--debug
```
Same applies for a custom semver line regex in order to extract the semantic
version part from a full version line, use the `semver_line_regex` argument to
adjust the regular expression to your needs.
### Custom template file
Beside the default supported [template files][ref-templates-folder] users can
also provide custom template files.
This is the list of currently available variables
| Name | Description |
| ----------------------------- | --------------------------------------------------------- |
| `major_version` | Major version, incompatible API changes |
| `minor_version` | Minor version, add functionality (backwards-compatible) |
| `patch_version` | Patch version, bug fixes (backwards-compatible) |
| `prerelease_data` | pre-release data, if available |
| `build_data` | Build metadata, if available |
| `file_name` | User specified name of rendered file |
| `file_name_without_suffix` | User specified name of rendered file without suffix |
| `template_name` | Name of rendered template file |
| `template_name_without_suffix`| Name of rendered template file without suffix |
| Custom keyword | Provided by the user via `--additional_template_data` |
```bash
additional_data="{\"creation_datetime\": \"$(date +"%Y-%m-%dT%H:%M:%S")\", \"machine_name\": \"$(whoami)\"}"
changelog2version \
--changelog_file changelog.md \
--version_file examples/version_info.c \
--template_file examples/version_info.c.template \
--additional_template_data "${additional_data}" \
--debug
# or less fancy
changelog2version \
--changelog_file changelog.md \
--version_file examples/version_info.c \
--template_file examples/version_info.c.template \
--additional_template_data '{"creation_datetime": "2022-08-05T21:11:12", "machine_name": "Death Star"}' \
--debug
```
Executing the created example file `examples/version_info.c` will print the
following content (datetime and creator might be different)
```
Script version is (major.minor.patch): 0.4.0
Prerelease data: None
Prerelease data: None
Creation datetime: 2022-08-05T21:11:12
Created by Death Star
```
### Additional version info content
To create custom release candidate packages the python version file variable
`__version__` can be exended with a custom string.
Choose the additional version info content carefully as not everything is
supported by PyPi, see the
[Python Core metadata specifications][ref-py-core-metadata-spec] and
[PEP440][ref-pep440]
```bash
changelog2version \
--changelog_file changelog.md \
--version_file examples/version.py \
--version_file_type py \
--additional_version_info="rc1234" \
--debug
```
```
#!/usr/bin/env python3
# -*- coding: UTF-8 -*-
__version_info__ = ("0", "5", "0")
__version__ = '.'.join(__version_info__) + '-rc1234'
```
## Contributing
### Unittests
Run the unittests locally with the following command after installing this
package in a virtual environment or by using `tox` to create one on each run.
```bash
# install the package with all its development dependencies
pip install .[dev]
# run all tests
nose2 --config tests/unittest.cfg
# run only one specific tests
nose2 tests.test_extract_version.TestExtractVersion.test_version_line_regex
```
Generate the coverage files with
```bash
python create_report_dirs.py
coverage html
```
The coverage report is placed at `reports/coverage/html/index.html`
