📝 Walkthrough

Walkthrough

CommandManager 0.3 adds named configuration settings that functions can declare for step-argument substitution. Configuration validation checks setting definitions and declarations. The README and example configuration document and demonstrate settings, including an icons-sync entry point.

Changes

Function Settings

Layer / File(s)	Summary
Define and validate settings cm.swift, Tests/CommandManagerTests/ConfigurationTests.swift, Tests/CommandManagerTests/Support.swift	Configuration decodes settings and function declarations. Validation checks setting names, values, references, and conflicts with parameters. Tests cover invalid settings and declarations.
Substitute settings at runtime cm.swift, Tests/CommandManagerTests/CommandExecutionTests.swift	Runner includes each function’s declared settings when rendering step arguments. Tests cover substitution in entry and called functions.
Document and configure the settings example README.md, examples/cm.json, cm.swift, Tests/CommandManagerTests/CommandExecutionTests.swift, Tests/CommandManagerTests/VersionTests.swift	README and the example configuration describe and demonstrate settings, including the icons-sync entry point. CommandManager and its version tests now use version 0.3.

Merge Risk: 🟡 Moderate · up to 5b22a

Settings are intended to hold secrets such as a Figma token, but CommandManager prints each command with the substituted value before running it. The token therefore appears in terminal output and in any captured logs. The documented example also embeds the token in shell code, so tokens containing shell-special characters can export incorrectly or break the command. Address both before merging.

Inline comments:
In `@cm.swift`:
- Line 362: Update the command assembly using settingValues(for: function) so
secret settings are not included in echoed rendered arguments or process
arguments; pass those credentials to the child through a non-echoed environment
channel instead.

In `@examples/cm.json`:
- Line 30: Update the `zsh -c` invocation in `examples/cm.json` at lines 30-30
to use a fixed shell program that assigns `FIGMA_TOKEN` from `$1`, passing
`${FIGMA_TOKEN}` as a separate positional argument; make the same change to the
documented example in `README.md` at lines 141-142.
