This provides
a [build hook](https://hatch.pypa.io/latest/config/build/#build-hooks) plugin
for [Hatch](https://github.com/pypa/hatch) to automatically generate a
manual page from an `ArgumentParser` object,
using [argparse-manpage](https://github.com/praiskup/argparse-manpage)
by [Pavel Raiskup](https://github.com/praiskup).

## Explanation

This plugin is not an official project of
[argparse-manpage](https://github.com/praiskup/argparse-manpage).
Instead, it acts as a wrapper around it, making it available to Hatch users.
As such, if argparse-manpage changes in ways incompatible with this 
plugin, this plugin may not function as expected.

This plugin has been tested against argparse-manpage version 4.5.

## Configuration

The [build hook plugin](https://hatch.pypa.io/latest/plugins/build-hook/)
name is `argparse-manpage`.

### Calling the plugin

Modify `pyproject.toml` to include the plugin as a build dependency:

```toml
[build-system]
requires = ["hatchling", "hatch-argparse-manpage"]
build-backend = "hatchling.build"
```

### Generating the manual page

This plugin requires the directories storing the generated man pages are 
within the project's base directory, and are not equal to the project's base 
directory.

For example, for a project named `myproject`, and a src layout
`src/myproject`, an acceptable directory in which to store a
man page would be `man`.

Using the configuration option `[tool.hatch.build.hooks.argparse-manpage]`, 
specify the man pages using the format defined by 
[argparse-manpage](https://github.com/praiskup/argparse-manpage).  

For example:
```toml
[tool.hatch.build.hooks.argparse-manpage]
manpages = [
    "man/foo.1:object=parser:pyfile=bin/foo.py",
    "man/bar.1:function=get_parser:pyfile=bin/bar",
    "man/baz.1:function=get_parser:pyfile=bin/bar:prog=baz",
]
```

### Extra options

#### Project URLs
If a URL is not specified in the man page's build configuration, this plugin
extracts it from the `[project.urls]` section of the project's pyproject.toml:

1. If a homepage URL is specified, then it is used.
2. If not, if only one URL is specified, it is used.

Argparse-manpage uses a project URL to 
generate a man section that explains where to download the program the 
page is being built for. 

To suppress this behavior, set `include-url` to false (the default value is 
true):
```toml
[tool.hatch.build.hooks.argparse-manpage]
include-url = false
manpages = [
    "man/foo.1:object=parser:pyfile=bin/foo.py",
    "man/bar.1:function=get_parser:pyfile=bin/bar",
    "man/baz.1:function=get_parser:pyfile=bin/bar:prog=baz",
]
```

#### Argparse-manpage invocation

This plugin defaults to calling argparse-manpage's Python code directly. If 
this generates an exception, this plugin will attempt to call argparse-manpage 
as a command line program. To force the use of argparse-manpage as a 
command line program, set `force-command-line` to true (the default value is 
false):
```toml
[tool.hatch.build.hooks.argparse-manpage]
force-command-line = true
manpages = [
    "man/foo.1:object=parser:pyfile=bin/foo.py",
    "man/bar.1:function=get_parser:pyfile=bin/bar",
    "man/baz.1:function=get_parser:pyfile=bin/bar:prog=baz",
]
```

## Cleaning output files

The plugin includes logic to remove the files it outputs using hatch's
`clean` hook. As well as individual files, any output directories created
will also be removed, as long as these directories do not contain files
created by something other than this plugin.

## History

The code to parse the pyproject.toml config in this plugin overlaps with
the code in [argparse-manpage](https://github.com/praiskup/argparse-manpage),
but differs in that it is rewritten to conform to contemporary Python 
stylistic conventions, as well as the specific needs of this plugin.
