Rating: 62
Author: OreStudio

When you need to add CLI commands for a new entity in ores.cli. This skill guides you through creating the options structs, entity parser, and application logic following established patterns.

Prerequisites:

•The domain type must already exist
•The repository for CRUD operations must be implemented
•Table I/O and JSON I/O must be available for output formatting

These are all implemented by domain-type-creator skill.

How to use this skill

•Gather entity requirements (name, operations needed, parameters).
•Follow the detailed instructions to create CLI support in phases.
•Each phase ends with a PR checkpoint - raise PR, wait for review, merge.
•Create a fresh branch from main for the next phase (see feature-branch-manager).
•Build and test after each step.

PR Strategy

This skill is structured into three phases, each resulting in a separate PR.

Phase	Steps	PR Title Template
1	Steps 1-4	`[cli] Add <entity> list and export commands`
2	Steps 5-7	`[cli] Add <entity> add and delete commands`
3	Step 8	`[doc] Add <entity> CLI command recipes`

After each PR is merged, use feature-branch-manager to transition to the next phase.

Detailed instructions

The following sections describe the step-by-step process for creating CLI commands for an entity.

Gather Requirements

Before starting, gather the following information:

•
Entity name: The name of the entity (e.g., currency, account, feature_flags).
•
Component location: Which domain the entity belongs to (e.g., ores.refdata, ores.iam).
•
Command name: The CLI command name (typically plural with hyphens, e.g., currencies, accounts, feature-flags).
•
Operations needed:
- • Import from external files (ORE XML, etc.)
- • Export to external formats (XML, CSV)
- • List in internal formats (JSON, table)
- • Delete by key
- • Add new entity from command-line parameters
•
Key field: The primary identifier for filtering (e.g., iso_code for currencies).
•
Required add parameters: What fields are required when adding a new entity.
•
Optional add parameters: What fields have defaults.

Phase 1: List and Export Commands

This phase creates the entity parser with basic list/export operations. After completing Steps 1-4, raise a PR.

Suggested PR title: [cli] Add <entity> list and export commands

Step 1: Add Entity Enum Value

Add the entity to the enumeration of available entities in ~/Development/OreStudio/OreStudio.local1/ as follows:

cpp

enum class entity {
    currencies,
    accounts,
    feature_flags,
    login_info,
    <entity>  // Add new entity here
};

Step 2: Create Entity Parser

Phase 1 Checkpoint: Raise PR

At this point:

•Build and verify: cmake --build --preset linux-clang-debug
•Test manually: ./ores.cli <entities> --help
•Test list: ./ores.cli <entities> list --format table
•Commit all changes.
•Push branch and raise PR.

PR Title: [cli] Add <entity> list and export commands

PR Description:

code

## Summary

- Add <entities> entity enum value
- Create <entities>_parser for command handling
- Implement list and export operations with JSON/table formats
- Register in main parser

## Test Plan

- [ ] Build succeeds
- [ ] `<entities> --help` shows available operations
- [ ] `<entities> list --format json` outputs JSON
- [ ] `<entities> list --format table` outputs table

Wait for review feedback and merge before continuing to Phase 2.

Phase 2: Add and Delete Commands

After Phase 1 PR is merged, use feature-branch-manager to transition to Phase 2.

Suggested PR title: [cli] Add <entity> add and delete commands

Step 5: Create Add Options Struct

Create the options struct for add command parameters.

Step 7: Extend Parser and Application for Add/Delete

Add the add and delete operations to the parser and application.

Parser changes

Update projects/ores.cli/src/config/entity_parsers/<entities>_parser.cpp:

•Add include:

cpp

#include "ores.cli/config/add_<entity>_options.hpp"

•Add command names:

cpp

const std::string delete_command_name("delete");
const std::string add_command_name("add");

const std::vector<std::string> allowed_operations{
    export_command_name, list_command_name,
    delete_command_name, add_command_name
};

•Add options description function:

cpp

/**
 * @brief Creates the options related to adding <entities>.
 */
options_description make_add_<entity>_options_description() {
    options_description r("Add <Entity> Options");
    r.add_options()
        ("<key-field>",
            value<std::string>(),
            "<Key field> (required)")
        ("optional-field1",
            value<std::string>()->default_value(""),
            "Optional field 1")
        ("optional-field2",
            value<int>()->default_value(0),
            "Optional field 2")
        ("modified-by",
            value<std::string>(),
            "Username of modifier (required)");

    return r;
}

•Add read function:

cpp

/**
 * @brief Reads the add configuration from the variables map for <entities>.
 */
ores::cli::config::add_<entity>_options
read_add_<entity>_options(const variables_map& vm) {
    ores::cli::config::add_<entity>_options r;

    if (vm.count("modified-by") == 0) {
        BOOST_THROW_EXCEPTION(
            parser_exception("Must supply --modified-by for add command."));
    }
    r.modified_by = vm["modified-by"].as<std::string>();

    // Required fields
    if (vm.count("<key-field>") == 0) {
        BOOST_THROW_EXCEPTION(
            parser_exception("Must supply --<key-field> for add command."));
    }
    r.<key_field> = vm["<key-field>"].as<std::string>();

    // Optional fields
    if (vm.count("optional-field1") != 0)
        r.optional_field1 = vm["optional-field1"].as<std::string>();
    if (vm.count("optional-field2") != 0)
        r.optional_field2 = vm["optional-field2"].as<int>();

    return r;
}

•Update help operations list:

cpp

const std::vector<std::pair<std::string, std::string>> operations = {
    {"export", "Export <entities> to external formats"},
    {"list", "List <entities> as JSON or table"},
    {"delete", "Delete a <entity> by <key>"},
    {"add", "Add a new <entity>"}
};

•Add operation handlers in handle_<entities>_command():

cpp

} else if (operation == delete_command_name) {
    auto d = add_common_options(make_delete_options_description());
    if (has_help) {
        print_help_command("<entities> delete", d, info);
        return {};
    }
    store(command_line_parser(o).options(d).run(), vm);
    store(parse_environment(d, name_mapper), vm);
    r.deleting = read_delete_options(vm, entity::<entities>);
} else if (operation == add_command_name) {
    auto d = add_common_options(make_add_<entity>_options_description());
    if (has_help) {
        print_help_command("<entities> add", d, info);
        return {};
    }
    store(command_line_parser(o).options(d).run(), vm);
    store(parse_environment(d, name_mapper), vm);
    r.adding = read_add_<entity>_options(vm);
}

Application changes

Update projects/ores.cli/src/app/application.cpp:

•Add include:

cpp

#include "ores.cli/config/add_<entity>_options.hpp"

•Add delete method:

cpp

void application::
delete_<entity>(const config::delete_options& cfg) const {
    BOOST_LOG_SEV(lg(), debug) << "Deleting <entity>: " << cfg.key;
    <component>::repository::<entity>_repository repo(context_);
    repo.remove(cfg.key);
    output_stream_ << "<Entity> deleted successfully: " << cfg.key << std::endl;
    BOOST_LOG_SEV(lg(), info) << "Deleted <entity>: " << cfg.key;
}

•Add to delete_data() switch:

cpp

case config::entity::<entities>:
    delete_<entity>(cfg);
    break;

•Add add method:

cpp

void application::
add_<entity>(const config::add_<entity>_options& cfg) const {
    BOOST_LOG_SEV(lg(), info) << "Adding <entity>: " << cfg.<key_field>;

    // Construct <entity> from command-line arguments
    <component>::domain::<entity> item;
    item.<key_field> = cfg.<key_field>;
    item.optional_field1 = cfg.optional_field1.value_or("");
    item.optional_field2 = cfg.optional_field2.value_or(0);
    item.recorded_by = cfg.modified_by;

    // Write to database
    <component>::repository::<entity>_repository repo(context_);
    repo.write(item);

    output_stream_ << "Successfully added <entity>: " << item.<key_field> << std::endl;
    BOOST_LOG_SEV(lg(), info) << "Added <entity>: " << item.<key_field>;
}

•Add to add_data() visitor:

cpp

} else if constexpr (std::is_same_v<T, config::add_<entity>_options>) {
    add_<entity>(opts);
}

•Update application header with new method declarations.

Update parser command description

In parser.cpp, update the command description:

cpp

const std::string <entities>_command_desc("Manage <entities> (list, export, delete, add).");

Commit message

code

[cli] Add <entity> add and delete operations

Implement add command with entity-specific options and
delete command for removing <entities> by key.

Phase 2 Checkpoint: Raise PR

At this point:

•Build and verify: cmake --build --preset linux-clang-debug
•Test add: ./ores.cli <entities> add --<key-field> test --modified-by admin
•Test delete: ./ores.cli <entities> delete --key test
•Commit all changes.
•Push branch and raise PR.

PR Title: [cli] Add <entity> add and delete commands

PR Description:

code

## Summary

- Add add_<entity>_options struct for add parameters
- Implement add command for creating new <entities>
- Implement delete command for removing <entities> by key
- Update parser to support all four operations

## Test Plan

- [ ] Build succeeds
- [ ] `<entities> add --help` shows required parameters
- [ ] `<entities> add` creates new <entity>
- [ ] `<entities> delete --key <key>` removes <entity>

Wait for review feedback and merge before continuing to Phase 3.

Phase 3: Recipe Documentation

After Phase 2 PR is merged, use feature-branch-manager to transition to Phase 3.

Suggested PR title: [doc] Add <entity> CLI command recipes

Step 8: Add CLI Recipes

Add all new commands to CLI recipes following the ores-cli-recipes skill. This ensures every command is documented with runnable examples.

File to modify

doc/recipes/cli_recipes.org

Recipe requirements

Create recipes that test every command added for the entity:

•Help recipe: Show the entity command help output
•List recipe: Demonstrate listing all entities (JSON and table formats)
•Add recipe: Demonstrate creating a new entity
•Delete recipe: Demonstrate deleting an entity

Recipe section structure

Add a new section for the entity following the existing pattern in cli_recipes.org:

#+begin_src fundamental

<Entities>

<Entity> management operations from the ORE Studio <Component> Component.

Help

Show available operations for <entities>.

./ores.cli <entities> --help

List

List all <entities> in table format.

export ORES_CLI_DB_PASSWORD
./ores.cli <entities> list ${db_args} ${log_args} --format table

List as JSON

List all <entities> in JSON format.

export ORES_CLI_DB_PASSWORD
./ores.cli <entities> list ${db_args} ${log_args} --format json

Add

Create a new <entity>.

export ORES_CLI_DB_PASSWORD
./ores.cli <entities> add ${db_args} ${log_args} \
  --<key-field> test_value \
  --modified-by admin

Delete

Delete a <entity> by key.

export ORES_CLI_DB_PASSWORD
./ores.cli <entities> delete ${db_args} ${log_args} --key test_value

#+end_src

Recipe conventions

•Set :header-args+: :wrap src json at section level for default JSON output
•Use :wrap src text override for help and table output
•Include export ORES_CLI_DB_PASSWORD before commands needing DB access
•Use ${db_args} and ${log_args} variables (defined in file header)
•Add descriptive paragraph before each recipe explaining what it demonstrates
•Link to the component's org-mode documentation using [[id:...][...]]

Updating ores-cli-recipes entity table

After adding recipes, update the entity operations table in the ores-cli-recipes skill (doc/skills/ores-cli-recipes/skill.org) to include the new entity:

fundamental

| <entities>    | list, delete, add                       |

Commit message

code
