Runtime behavior

Initialization

Applications will bootstrap themselves on the first run. All subsequent invocations will only check if the installation directory exists and nothing else, to maximize CLI responsiveness.

Note

The following diagram shows the possible behavior at runtime. The nodes with rounded edges are conditions and those with jagged edges are actions.

Most nodes are clickable and will take you to the relevant documentation.

Before building your application, you must configure your project at the very least.

After you have done that, your application can be built using a local copy of this repository or via installation with Cargo.

Tip

For a more streamlined workflow, consider using the built-in app build target of Hatch.

"},{"location":"build/#local-repository","title":"Local repository","text":"

The recommended method of downloading the repository is via the source asset archives attached to each release.

The latest release can always be downloaded at the following URLs:

Specific releases may be downloaded at the following URLs, replacing X.Y.Z with the desired version:

After unpacking the repository, enter the directory and run:

cargo build --release\n

The executable will be located at target/release/pyapp.exe if on Windows or target/release/pyapp otherwise. If a particular target has been set (or when cross compiling since one will always be set), then the release directory will be nested one level deeper under target/<TARGET>.

"},{"location":"build/#installation","title":"Installation","text":"

Select the directory in which to build the executable with the --root option and run:

cargo install pyapp --force --root <DIR>\n

The executable will be located at <DIR>/bin/pyapp.exe if on Windows or <DIR>/bin/pyapp otherwise.

Specific versions may be chosen with the --version flag.

Note: If you want to cross compile, this method of building is currently unsupported.

"},{"location":"build/#cross-compilation","title":"Cross compilation","text":"

Configuration for cross is validated by CI to ensure all known environment variable options are passed through to the containers.

When embedding the project or the distribution using a local path, you must use the local repository way of building and ensure that the configured files to embed reside within the repository and the options refer to relative paths.

"},{"location":"build/#caveats","title":"Caveats","text":"

Some targets like powerpc64le-unknown-linux-gnu need extra Cargo configuration to build properly. If there exists a file named .cargo/config_<TARGET>.toml, then you will need to build using the local repository way and rename that file to .cargo/config.toml before builds.

All configuration is done with environment variables.

"},{"location":"config/#project","title":"Project","text":"

There are 3 ways to configure runtime installation, none of which will occur when disabled.

The project name and version must be known in all cases.

"},{"location":"config/#package-index","title":"Package index","text":"

The desired project name and version are configured with the PYAPP_PROJECT_NAME and PYAPP_PROJECT_VERSION options, respectively. The project name must adhere to PEP 508 and will be normalized during builds according to PEP 503.

"},{"location":"config/#dependency-file","title":"Dependency file","text":"

You may install your project using a dependency file with the PYAPP_PROJECT_DEPENDENCY_FILE option which should be a local path to the file. In this mode, the project name and version have nothing to do with installation and are just used as metadata.

The following formats are supported:

Extensions Description .txt.in This is the requirements file format"},{"location":"config/#project-embedding","title":"Embedding","text":"

You may embed the project with the PYAPP_PROJECT_PATH option which should be a path to a wheel ending in .whl or a source distribution ending in .tar.gz.

Note

The project name and version is automatically derived from the metadata files inside.

"},{"location":"config/#execution-mode","title":"Execution mode","text":"

The following options are mutually exclusive:

Option Description PYAPP_EXEC_MODULE This is the name of the module to execute via python -m <MODULE> PYAPP_EXEC_SPEC This is an object reference to execute e.g. pkg.foo:cli PYAPP_EXEC_CODE This is arbitrary code to run via python -c <CODE> (the spec option uses this internally)

If none are set then the PYAPP_EXEC_MODULE option will default to the value of PYAPP_PROJECT_NAME with hyphens replaced by underscores.

"},{"location":"config/#python-distribution","title":"Python distribution","text":""},{"location":"config/#known","title":"Known","text":"

Setting the PYAPP_PYTHON_VERSION option will determine the distribution used at runtime based on the environment at build time. If unset then the default will be the latest stable minor version of CPython.

"},{"location":"config/#cpython","title":"CPython","text":"ID 3.7 3.8 3.9 3.10 3.11

The source of distributions is the python-build-standalone project.

Some distributions have variants that may be configured with the PYAPP_DISTRIBUTION_VARIANT option:

Platform Options Linux Windows "},{"location":"config/#pypy","title":"PyPy","text":"ID pypy2.7 pypy3.9 pypy3.10

The source of distributions is the PyPy project.

"},{"location":"config/#custom","title":"Custom","text":"

You may explicitly set the PYAPP_DISTRIBUTION_SOURCE option which overrides the known distribution settings. The source must be a URL that points to an archived version of the desired Python distribution.

Setting this manually may require you to define extra metadata about the distribution that is required for correct runtime behavior.

"},{"location":"config/#format","title":"Format","text":"

The following formats are supported for the PYAPP_DISTRIBUTION_FORMAT option, with the default chosen based on the ending of the source URL:

Format Extensions Description tar|bzip2 A tar file with bzip2 compression tar|gzip A tar file with gzip compression tar|zstd A tar file with Zstandard compression zip A ZIP file with DEFLATE compression"},{"location":"config/#python-location","title":"Python location","text":"

You may set the relative path to the Python executable after unpacking the archive with the PYAPP_DISTRIBUTION_PYTHON_PATH option. The default is python.exe on Windows and bin/python3 on all other platforms.

"},{"location":"config/#site-packages-location","title":"Site packages location","text":"

You may set the relative path to the site-packages directory after unpacking the archive with the PYAPP_DISTRIBUTION_SITE_PACKAGES_PATH option. The default is Lib\\site-packages on Windows and lib/python<ID>/site-packages on all other platforms where <ID> is the distribution ID is defined.

"},{"location":"config/#pip-availability","title":"pip availability","text":"

You may indicate whether pip is already installed by setting the PYAPP_DISTRIBUTION_PIP_AVAILABLE option to true or 1. This elides the check for installation when upgraded virtual environments are enabled.

"},{"location":"config/#distribution-embedding","title":"Embedding","text":"

You may set the PYAPP_DISTRIBUTION_EMBED option to true or 1 to embed the distribution in the executable at build time to avoid fetching it at runtime. When distribution embedding is enabled, you can set the PYAPP_DISTRIBUTION_PATH option to use a local path rather than fetching the source.

"},{"location":"config/#pip","title":"pip","text":"

These options have no effect when the project installation is disabled.

"},{"location":"config/#externally-managed","title":"Externally managed","text":"

You may set the PYAPP_PIP_EXTERNAL option to true or 1 to use the standalone versions of pip rather than whatever the distribution provides.

By default, the latest version is used. You may use a specific X.Y.Z version by setting the PYAPP_PIP_VERSION option.

Tip

This provides a significant installation speed up when full isolation is not enabled.

"},{"location":"config/#extra-arguments","title":"Extra arguments","text":"

You may set the PYAPP_PIP_EXTRA_ARGS option to provide extra arguments to the pip install command at runtime when installing or updating the project e.g. --index-url URL --only-binary :all:.

"},{"location":"config/#allowing-configuration","title":"Allowing configuration","text":"

You may set the PYAPP_PIP_ALLOW_CONFIG option to true or 1 to allow the use of environment variables and other configuration at runtime.

"},{"location":"config/#full-isolation","title":"Full isolation","text":"

You may set the PYAPP_FULL_ISOLATION option to true or 1 to provide each installation with a full copy of the distribution rather than a virtual environment.

"},{"location":"config/#virtual-environments","title":"Virtual environments","text":"

When full isolation is not enabled, you may set the PYAPP_UPGRADE_VIRTUALENV option to true or 1 to create virtual environments with virtualenv rather than the standard library's venv module.

"},{"location":"config/#skipping-project-installation","title":"Skipping project installation","text":"

You may set the PYAPP_SKIP_INSTALL option to true or 1 to skip installing the project in the distribution. This allows for entirely predefined distributions and thus no network calls at runtime if used in conjunction with distribution embedding.

"},{"location":"config/#installation-indicator","title":"Installation indicator","text":"

The environment variable that is used for detection may be set to the path of the executable at runtime if you set the PYAPP_PASS_LOCATION option to true or 1. This is useful if your application wishes to in some way manage itself.

"},{"location":"config/#management-command","title":"Management command","text":"

You may set the PYAPP_SELF_COMMAND option to override the default name (self) of the management command group. Setting this to none effectively disables the use of management commands.

When enabled, the value will be available at runtime as the PYAPP_COMMAND_NAME environment variable.

"},{"location":"config/#metadata-template","title":"Metadata template","text":"

You may set a custom template used to output metadata with the PYAPP_METADATA_TEMPLATE option which supports the following placeholders:

Placeholder Description {project} The normalized project name {version} The currently installed version of the project

The default template is {project} v{version} if this option is unset.

This is useful for setting custom commands for the Starship prompt. The following example configuration assumes that the built executable has been renamed to foo:

format = \"\"\"\n...\n${custom.foo}\\\n...\n$line_break\\\n...\n$character\"\"\"\n\n# <clipped>\n\n[custom.foo]\ncommand = \"foo self metadata\"\nwhen = true\n## Windows\n# shell = [\"cmd\", \"/C\"]\n## Other\n# shell = [\"sh\", \"--norc\"]\n

Before building your application, you must configure your project at the very least.

After you have done that, your application can be built using a local copy of this repository or via installation with Cargo.

Tip

For a more streamlined workflow, consider using the built-in app build target of Hatch.

"},{"location":"build/#local-repository","title":"Local repository","text":"

The recommended method of downloading the repository is via the source asset archives attached to each release.

The latest release can always be downloaded at the following URLs:

Specific releases may be downloaded at the following URLs, replacing X.Y.Z with the desired version:

After unpacking the repository, enter the directory and run:

cargo build --release\n

The executable will be located at target/release/pyapp.exe if on Windows or target/release/pyapp otherwise. If a particular target has been set (or when cross compiling since one will always be set), then the release directory will be nested one level deeper under target/<TARGET>.

"},{"location":"build/#installation","title":"Installation","text":"

Select the directory in which to build the executable with the --root option and run:

cargo install pyapp --force --root <DIR>\n

The executable will be located at <DIR>/bin/pyapp.exe if on Windows or <DIR>/bin/pyapp otherwise.

Specific versions may be chosen with the --version flag.

Note: If you want to cross compile, this method of building is currently unsupported.

"},{"location":"build/#cross-compilation","title":"Cross compilation","text":"

Configuration for cross is validated by CI to ensure all known environment variable options are passed through to the containers.

When embedding the project or the distribution using a local path, you must use the local repository way of building and ensure that the configured files to embed reside within the repository and the options refer to relative paths.

"},{"location":"build/#caveats","title":"Caveats","text":"

Some targets like powerpc64le-unknown-linux-gnu need extra Cargo configuration to build properly. If there exists a file named .cargo/config_<TARGET>.toml, then you will need to build using the local repository way and rename that file to .cargo/config.toml before builds.

This is the initial public release.

"},{"location":"config/","title":"Configuration","text":"

All configuration is done with environment variables.

"},{"location":"config/#project","title":"Project","text":"

There are 3 ways to configure runtime installation, none of which will occur when disabled.

The project name and version must be known in all cases.

"},{"location":"config/#package-index","title":"Package index","text":"

The desired project name and version are configured with the PYAPP_PROJECT_NAME and PYAPP_PROJECT_VERSION options, respectively. The project name must adhere to PEP 508 and will be normalized during builds according to PEP 503.

"},{"location":"config/#dependency-file","title":"Dependency file","text":"

You may install your project using a dependency file with the PYAPP_PROJECT_DEPENDENCY_FILE option which should be a local path to the file. In this mode, the project name and version have nothing to do with installation and are just used as metadata.

The following formats are supported:

Extensions Description .txt.in This is the requirements file format"},{"location":"config/#project-embedding","title":"Embedding","text":"

You may embed the project with the PYAPP_PROJECT_PATH option which should be a path to a wheel ending in .whl or a source distribution ending in .tar.gz.

Note

The project name and version is automatically derived from the metadata files inside.

"},{"location":"config/#execution-mode","title":"Execution mode","text":"

The following options are mutually exclusive:

Option Description PYAPP_EXEC_MODULE This is the name of the module to execute via python -m <MODULE> PYAPP_EXEC_SPEC This is an object reference to execute e.g. pkg.foo:cli PYAPP_EXEC_CODE This is arbitrary code to run via python -c <CODE> (the spec option uses this internally)

If none are set then the PYAPP_EXEC_MODULE option will default to the value of PYAPP_PROJECT_NAME with hyphens replaced by underscores.

"},{"location":"config/#python-distribution","title":"Python distribution","text":""},{"location":"config/#known","title":"Known","text":"

Setting the PYAPP_PYTHON_VERSION option will determine the distribution used at runtime based on the environment at build time. If unset then the default will be the latest stable minor version of CPython.

"},{"location":"config/#cpython","title":"CPython","text":"ID 3.7 3.8 3.9 3.10 3.11

The source of distributions is the python-build-standalone project.

Some distributions have variants that may be configured with the PYAPP_DISTRIBUTION_VARIANT option:

Platform Options Linux Windows "},{"location":"config/#pypy","title":"PyPy","text":"ID pypy2.7 pypy3.9 pypy3.10

The source of distributions is the PyPy project.

"},{"location":"config/#custom","title":"Custom","text":"

You may explicitly set the PYAPP_DISTRIBUTION_SOURCE option which overrides the known distribution settings. The source must be a URL that points to an archived version of the desired Python distribution.

Setting this manually may require you to define extra metadata about the distribution that is required for correct runtime behavior.

"},{"location":"config/#format","title":"Format","text":"

The following formats are supported for the PYAPP_DISTRIBUTION_FORMAT option, with the default chosen based on the ending of the source URL:

Format Extensions Description tar|bzip2 A tar file with bzip2 compression tar|gzip A tar file with gzip compression tar|zstd A tar file with Zstandard compression zip A ZIP file with DEFLATE compression"},{"location":"config/#python-location","title":"Python location","text":"

You may set the relative path to the Python executable after unpacking the archive with the PYAPP_DISTRIBUTION_PYTHON_PATH option. The default is python.exe on Windows and bin/python3 on all other platforms.

"},{"location":"config/#site-packages-location","title":"Site packages location","text":"

You may set the relative path to the site-packages directory after unpacking the archive with the PYAPP_DISTRIBUTION_SITE_PACKAGES_PATH option. The default is Lib\\site-packages on Windows and lib/python<ID>/site-packages on all other platforms where <ID> is the distribution ID is defined.

"},{"location":"config/#pip-availability","title":"pip availability","text":"

You may indicate whether pip is already installed by setting the PYAPP_DISTRIBUTION_PIP_AVAILABLE option to true or 1. This elides the check for installation when upgraded virtual environments are enabled.

"},{"location":"config/#distribution-embedding","title":"Embedding","text":"

You may set the PYAPP_DISTRIBUTION_EMBED option to true or 1 to embed the distribution in the executable at build time to avoid fetching it at runtime. When distribution embedding is enabled, you can set the PYAPP_DISTRIBUTION_PATH option to use a local path rather than fetching the source.

"},{"location":"config/#pip","title":"pip","text":"

These options have no effect when the project installation is disabled.

"},{"location":"config/#externally-managed","title":"Externally managed","text":"

You may set the PYAPP_PIP_EXTERNAL option to true or 1 to use the standalone versions of pip rather than whatever the distribution provides.

By default, the latest version is used. You may use a specific X.Y.Z version by setting the PYAPP_PIP_VERSION option.

Tip

This provides a significant installation speed up when full isolation is not enabled.

"},{"location":"config/#extra-arguments","title":"Extra arguments","text":"

You may set the PYAPP_PIP_EXTRA_ARGS option to provide extra arguments to the pip install command at runtime when installing or updating the project e.g. --index-url URL --only-binary :all:.

"},{"location":"config/#allowing-configuration","title":"Allowing configuration","text":"

You may set the PYAPP_PIP_ALLOW_CONFIG option to true or 1 to allow the use of environment variables and other configuration at runtime.

"},{"location":"config/#full-isolation","title":"Full isolation","text":"

You may set the PYAPP_FULL_ISOLATION option to true or 1 to provide each installation with a full copy of the distribution rather than a virtual environment.

"},{"location":"config/#virtual-environments","title":"Virtual environments","text":"

When full isolation is not enabled, you may set the PYAPP_UPGRADE_VIRTUALENV option to true or 1 to create virtual environments with virtualenv rather than the standard library's venv module.

"},{"location":"config/#skipping-project-installation","title":"Skipping project installation","text":"

You may set the PYAPP_SKIP_INSTALL option to true or 1 to skip installing the project in the distribution. This allows for entirely predefined distributions and thus no network calls at runtime if used in conjunction with distribution embedding.

"},{"location":"config/#installation-indicator","title":"Installation indicator","text":"

The environment variable that is used for detection may be set to the path of the executable at runtime if you set the PYAPP_PASS_LOCATION option to true or 1. This is useful if your application wishes to in some way manage itself.

"},{"location":"config/#management-command","title":"Management command","text":"

You may set the PYAPP_SELF_COMMAND option to override the default name (self) of the management command group. Setting this to none effectively disables the use of management commands.

When enabled, the value will be available at runtime as the PYAPP_COMMAND_NAME environment variable.

"},{"location":"config/#metadata-template","title":"Metadata template","text":"

You may set a custom template used to output metadata with the PYAPP_METADATA_TEMPLATE option which supports the following placeholders:

Placeholder Description {project} The normalized project name {version} The currently installed version of the project

The default template is {project} v{version} if this option is unset.

This is useful for setting custom commands for the Starship prompt. The following example configuration assumes that the built executable has been renamed to foo:

format = \"\"\"\n...\n${custom.foo}\\\n...\n$line_break\\\n...\n$character\"\"\"\n\n# <clipped>\n\n[custom.foo]\ncommand = \"foo self metadata\"\nwhen = true\n## Windows\n# shell = [\"cmd\", \"/C\"]\n## Other\n# shell = [\"sh\", \"--norc\"]\n
"},{"location":"runtime/","title":"Runtime behavior","text":""},{"location":"runtime/#initialization","title":"Initialization","text":"

Applications will bootstrap themselves on the first run. All subsequent invocations will only check if the installation directory exists and nothing else, to maximize CLI responsiveness.

Note

The following diagram shows the possible behavior at runtime. The nodes with rounded edges are conditions and those with jagged edges are actions.

Most nodes are clickable and will take you to the relevant documentation.

Projects are executed using execvp on non-Windows systems, replacing the process.

To provide consistent behavior on each user's machine:

"},{"location":"runtime/#detection","title":"Detection","text":"

A single environment variable called PYAPP is injected with the value of 1 (by default) when running applications and may be used to detect this mode of installation versus others.

"},{"location":"runtime/#location","title":"Location","text":"

The default location of your application's installation differs based on the operating system and can be overridden at runtime with the PYAPP_INSTALL_DIR_<PROJECT_NAME> environment variable where <PROJECT_NAME> is the uppercased version of the project name.

"},{"location":"runtime/#commands","title":"Commands","text":"

Built applications have a single top-level command group named self (by default) and all other invocations will be forwarded to your actual execution logic.

"},{"location":"runtime/#default","title":"Default","text":"

These commands are always exposed.

"},{"location":"runtime/#restore","title":"Restore","text":"
<EXE> self restore\n

This will wipe the installation and start fresh.

"},{"location":"runtime/#update","title":"Update","text":"
<EXE> self update\n

This will update the project to the latest available version in the currently used distribution.

"},{"location":"runtime/#optional","title":"Optional","text":"

These commands are hidden by default and each can be individually exposed by setting its corresponding PYAPP_EXPOSE_<COMMAND> option (e.g. PYAPP_EXPOSE_METADATA) to true or 1.

"},{"location":"runtime/#metadata","title":"Metadata","text":"
<EXE> self metadata\n

This displays customized output based on a template.

"},{"location":"runtime/#pip","title":"pip","text":"
<EXE> self pip\n

This directly invokes pip with the installed Python.

This directly invokes the installed Python.

"},{"location":"runtime/#python-path","title":"Python path","text":"
