chml.c - ChatML Message Wrapper

chml reads text from standard input and wraps it in a single ChatML message. It supports the system, assistant, and user roles, defaulting to user.

CLI

Examples

echo 'Hello' | ./bin/x86_64/linux/chml

echo 'You are a helpful assistant.' | ./bin/x86_64/linux/chml --role system

Output

<|im_start|>user
Hello
<|im_end|>

Parameters

Public API

#include "chml.h"

kc_chml_t *ctx = kc_chml_open();
kc_chml_set_role(ctx, KC_CHML_ROLE_SYSTEM);

char *msg = kc_chml_render(ctx, "You are a bot.");
printf("%s", msg);
free(msg);

kc_chml_close(ctx);

Role Constants

Lifecycle

• kc_chml_open() - Creates a new ChatML context with default role user. Returns NULL on failure.
• kc_chml_set_role() - Sets the message role. Returns KC_CHML_ERROR on invalid role.
• kc_chml_get_role() - Returns the current role constant.
• kc_chml_get_role_name() - Returns the role name string.
• kc_chml_render() - Allocates and returns a ChatML-formatted string. Caller must free().
• kc_chml_close() - Releases the context. Safe to call with NULL.

Beta Notice

This is a beta project tested only on Debian x86_64. It was created out of a personal need for these libraries, but no guarantees are provided regarding its stability or future support. You are free to test it, use it, and modify it as you please.

If you'd like to reach out, you can send an email to [email protected]. Please note that I do not accept pull requests; the goal is to avoid long-term dependency on platforms like GitHub, and I do not maintain fixed infrastructure to guarantee long-term stability for these projects.
