# PreTeXt-CLI

A package for authoring and building [PreTeXt](https://pretextbook.org) documents.

- GitHub: <https://github.com/PreTeXtBook/pretext-cli/>

## Documentation and examples for authors/publishers

Most documentation for PreTeXt authors and publishers is available at:

- <https://pretextbook.org/doc/guide/html/>

Authors and publishers may also find the examples catalog useful as well:

- <https://pretextbook.org/examples.html>

We have a few notes below (TODO: publish these in the Guide).

### Installation

#### Installing Python

PreTeXt-CLI requires the Python version specified in `pyproject.toml`.

To check your version, type this into your terminal or command prompt:

```
python -V
```

If your version is 2.x, try this instead
(and if so, either replace all future references to `python`
in these instructions with `python3`).

```
python3 -V
```

If you don't have a compatible Python available, try one of these:

- https://www.python.org/downloads/
  - Windows warning: Be sure to select the option adding Python to your Path.
- https://github.com/pyenv/pyenv#installation (Mac/Linux)
- https://github.com/pyenv-win/pyenv-win#installation (Windows)

#### Installing PreTeXt-CLI

Once you've confirmed that you're using a valid version of Python, just
run (replacing `python` with `python3` if necessary):

```
python -m pip install --user pretextbook
```

(It's also possible you may get an error like 
`error: invalid command 'bdist_wheel'`
— good news, you can ignore it!)

After installation, try to run:

```
pretext --help
```

If that works, great! Otherwise, it likely means that Python packages
aren't available on your “PATH”. In that case, replace all `pretext`
commands with `python -m pretext` instead:

```
python -m pretext --help
```

Either way, you're now ready to use the CLI, the `--help` option will explain how to use all the different
subcommands like `pretext new` and `pretext build`.

#### Upgrading PreTeXt-CLI
If you have an existing installation and you want to upgrade to a more recent version, you can run:

```
python -m pip install --upgrade pretextbook
```

#### Custom XSL

Custom XSL is not encouraged for most authors, but (for example) developers working
bleeding-edge XSL from core PreTeXt may want to call XSL different from that
which is shipped with a fixed version of the CLI. This may be accomplished by
adding an `<xsl/>` element to your target with a relative (to `project.ptx`) or
absolute path to the desired XSL. *(Note: this XSL must only import
other XSL files in the same directory or within subdirectories.)*

For example:

```
<target name="html">
  <format>html</format>
  <source>source/main.ptx</source>
  <publication>publication/publication.ptx</publication>
  <output-dir>output/html</output-dir>
  <xsl>../pretext/xsl/pretext-html.xsl</xsl>
</target>
```

If your custom XSL file needs to import the XSL
shipped with the CLI (e.g. `pretext-common.xsl`), then use the `@pretext-href`
attribute in your custom XSL's `<xsl:import/>` as follows:

```
<xsl:import pretext-href="pretext-common.xsl"/>
```

The CLI will treat this as follows:

```
<xsl:import href="/path/to/cli/xsl/on/your/disk/pretext-common.xsl"/>
```

## Development
**Note.** The remainder of this documentation is intended only for those interested
in contributing to the developement of this project.  Anyone who simply wishes to
*use* the PreTeXt-CLI can stop reading here. 

From the "Clone or Download" button on GitHub, copy the `REPO_URL` into the below
command to clone the project.

```bash
git clone [REPO_URL]
cd pretext-cli
```

### Using a valid Python installation

Developers and contributors must install a
version of Python that matching the requirements in `pyproject.toml`.

#### Using pyenv and poetry (Mac/Linux)

The `pyenv` tool for Linux automates the process of running the correct
version of Python when working on this project (even if you have
other versions of Python installed on your system).

- https://github.com/pyenv/pyenv#installation

Run the following, replacing `PYTHON_VERSION` with your desired version.

```
pyenv install PYTHON_VERSION
```

Then follow these instructions to install `poetry`.

- https://python-poetry.org/docs/#installation
    - Note 2022/06/21: you may ignore "This installer is deprecated". See
      [python-poetry/poetry/issues/4128](https://github.com/python-poetry/poetry/issues/4128)

Then you should be able to install dependencies into a virtual environment
with this command.

```
poetry install
```

Then to use the in-development package, you can either enter a poetry shell:

```
pretext --version # returns system version
poetry shell
pretext --version # returns version being developed
exit
pretext --version # returns system version
```

Or use the runner (as long as you remain within the package directory):

```
pretext --version             # returns system version
poetry run pretext --version  # returns version being developed
```

If you run `echo 'alias pr="poetry run"' >> ~/.bashrc` then restart your
shell, this becomes less of a mouthful:

```
pretext --version     # returns system version
pr pretext --version  # returns version being developed
```

#### Steps on Windows

In windows, you can either use the bash shell and follow the directions above,
or try [pyenv-win](https://github.com/pyenv-win/pyenv-win#installation).  In
the latter case, make sure to follow all the installation instructions, including
the **Finish the installation**.  Then proceed to follow the directions above to
install a version of python matching `.pyproject.toml`.  Finally, you may then need
to manually add that version of python to your path.

### Updating dependencies

To add dependencies for the package, run

```
poetry add DEPENDENCY-NAME
```

If someone else has added a dependency:

```
poetry install
```

### Syncing untracked updates

Updates to certain files tracked to the repository will
need to be rebuilt by each user when pulled from GitHub.

The file `pretext/__init__.py` tracks the upstream
commit of core PreTeXt XSL/Python code we're developing against
(from `PreTeXtBook/pretext`).
To grab these updates from upstream, run:

```
poetry run python scripts/update_core.py
```

If you instead want to point to a local copy of `PreTeXtBook/pretext`,
try this instead to set up symlinks:

```
poetry run python scripts/symlink_core.py path/to/pretext
```

Updates to `templates/` must be zipped and moved into
`pretext/static/templates`. This is done automatically by
running:

```
poetry run python scripts/zip_templates.py
```

### Packaging

To check if a successful build is possible:

```
poetry run python scripts/build_package.py
```

To publish a new alpha release, first add/commit any changes. Then
the following handles bumping versions, publishing to PyPI,
and associated Git management.

```
poetry run python scripts/release_alpha.py
```

Publishing a stable release is similar:

```
poetry run python scripts/release_stable.py # patch +0.+0.+1
poetry run python scripts/release_stable.py minor # +0.+1.0
poetry run python scripts/release_stable.py major # +1.0.0
```
