Tox Split Message

Library providing split message functionality for sending messages over Tox.

Although it is written for Tox use-case in mind, it's generic enough to be used to split any UTF-8 string in any, i.e. even not Tox-related, project.

It tries to split a UTF-8 encoded message on the nearest space or punctuation character, or if there are none, then on the nearest UTF-8 codepoint.

Example

Usage example with no error handling.

Splits a message in messages of TOX_MAX_MESSAGE_LENGTH size, trying to split on space, dot, comma or dash if present in last 1/4 of the message, instead of splitting in the middle of a word.

#include <tox/tox.h>
#include <tox_split_message.h>

typedef struct Message_info {
    Tox *tox;
    uint32_t friend_number;
} Message_info;

void split_message_handler(const uint8_t *message, size_t length, void *user_data)
{
    Message_info *mi = user_data;
    tox_friend_send_message(mi->tox, mi->friend_number, TOX_MESSAGE_TYPE_NORMAL,
                            message, length, NULL);
}

void my_client_send_message(Tox *tox, uint32_t friend_number, uint8_t *message,
                            size_t length)
{
    Message_info mi = {tox, friend_number};
    tsm_split_message(message, length, TOX_MAX_MESSAGE_LENGTH, (uint8_t*)" .,-",
                      TOX_MAX_FILENAME_LENGTH/4, split_message_handler, &mi);
}

Build

See INSTALL.md.

Alternatively, you could just drop the source code in your project, it's just 2 files of C with no external dependencies.
