geomancy 0.6.2b0

Geomancy validates deployment and development environments

geomancy

The geomancy tool makes it easy to check and validate environments, such as development, testing and production.

Currently, geomancy can check that:

• environment variables are properly set
• file and directory paths exist
• executables are available and, optionally, of the correct version
• check grouping and conditional evaluation
• supports setting values with environment variable substitution. ex: checkPath: {HOME}/.geomancy.toml

The following is an example geomancy run with an example checks file.

$ geo examples/geomancy.toml
========================= examples/geomancy.toml =========================
    checks (10 checks)
[✔]   Environment (2 checks)
[✔]     Check environment variable '{PATH}'...passed
[✔]     Check environment variable '{USER}'...passed
      Paths (4 checks)
[✔]     ChecksFile (3 checks)
[✔]       Check path 'examples/geomancy.toml'...passed
[✔]       Check path 'examples/pyproject.toml'...passed
[!]       Check path '.missing__.txt'...missing
[✔]   Executables (1 checks)
[✔]     Check executable 'python3>=3.11'...passed
========================= 11 checks passed in 0.00s ======================

Usage

1. Create a file containing checks. Either

   • .geomancy.toml in the project root. See the examples directory for examples.

   or

   • pyproject.toml with checks and config in the [tool.geomancy] section.

2. Run the geo

   $ geo
   

Format

Check Groups

Check groups are sections which contain one or more sub-checks.

name	description
desc	(Optional) The description for the check section
condition	(Optional) Either 'all' to require that all sub-checks pass or 'any' to require that only one sub-check passes. Default: 'all'

Examples

The following is a check group ChecksFile with 2 checks, Geomancy and Pyproject.

[checks.ChecksFile]
    desc = "Checks that at least one checks file exists"
    condition = "any"

    [checks.ChecksFile.Geomancy]
    desc = "Check for 'geomancy.toml' file"
    checkPath = "examples/geomancy.toml"
    type = "file"

    [checks.ChecksFile.Pyproject]
    desc = "Check for 'pyproject.toml' file"
    checkPath = "examples/pyproject.toml"
    type = "file"

The following is the same check group, but in abbreviated format.

[checks.ChecksFile]
    condition = "any"

    Geomancy = {checkPath = "examples/geomancy.toml", type = "file"}
    Pyproject = {checkPath = "examples/pyproject.toml", type = "file"}

Checks

checkEnv

Check the existence and, optionally, the value of an environment variable.

name	description
checkEnv	Environment variable to check, wrapped in curly braces for substitution. aliases: checkEnv, CheckEnv
desc	(Optional) The description for the check
regex	(Optional) A regular expression to check against the environment variable value

Examples

[checks.Environment.Username]
desc = "The current username"
checkEnv = "{USER}"
regex = "[a-z_][a-z0-9_-]*[$]?"

checkExec

Check the existence and, optionally, the version of available executables or commands.

name	description
checkExec	Executable to check. Additionally, an optional version check can be added with a test operator. aliases: checkExec, CheckExec
desc	(Optional) The description for the check

Examples

[checks.Executables.Ls]
desc = "List files"
checkExec = "ls"

[checks.Executables.Python]
desc = "Python interpreter (version 3.11 or higher)"
checkExec = "python3>=3.11"

checkPath

Check the existence and type of a path.

name	description
checkPath	Path to check, which may include environment variables wrapped in curly braces for substitution. aliases: checkPath, CheckPath
desc	(Optional) The description for the check
type	(Optional) Additionally check whether the path corresponds to a valid 'file' or 'dir'.

Examples

[checks.Environment.Pyproject]
desc = "A project's pyprojectfile"
checkPath = "./pyproject.toml"
path_type = "file"
