## `tppi` stands for Tilde Pipe Plus Interface | ||
|
||
> A simple communication helper and enclosing mechanism called **TPPI protocol**. | ||
There are two parts to this protocol: | ||
|
||
- *Organization* - Build the compatible data representation called **TPPI content**. | ||
- *Encapsulation* - Prepare a compatible packet with necessary safeguards called **TPPI packet**. | ||
|
||
This is **string oriented protocol** with *special safeguards* for **TPPI protocol.** | ||
|
||
The following symbols are considered special to **TPPI protocol**: | ||
|
||
- `~` Tilde Symbol | ||
- `|` Pipe Symbol | ||
- `+` Plus Symbol | ||
|
||
These *symbol are replaced* by the following as *safeguards* for **TPPI packet**: | ||
|
||
- `|` converts to `\\x7C` | ||
- `+` converts to `\\x2B` | ||
|
||
These *symbols are replaced* for *safeguards* in data specified for **TPPI contents** : | ||
|
||
`~` converts to `%7E` | ||
`|` converts to `%7C` | ||
`+` converts to `%2B` | ||
|
||
The **TPPI protocol** contains special annotations: | ||
|
||
- `~|` is used to indicate the **start** of the **TPPI Packet** | ||
- `|~` is used to indicate the **end** of the **TPPI Packet** | ||
- `|` is used to separate the **TPPI contents** in a **TPPI Packet** | ||
- `~` are used to organize the **TPPI contents** with Type, tags, & data. | ||
- `~||~` indicates a **TPPI packet** *without any contents* | ||
- `+` is used to join TPPI packets together. | ||
|
||
Collection rule for TPPI packets: | ||
|
||
- If **TPPI packet** are sent one at a time then no special addition is needed. | ||
- In case *collection* of **TPPI packets** need to be sent then `+` symbol is used. | ||
|
||
Rules for **TPPI content**: | ||
|
||
- The *content mist be filtered* with necessary *safeguards*. | ||
- **Type Signature**: Each **TPPI content** must have a **Type Signature** that tells what type of data it contains and helps in *Discovery process* later. In case no **Type Signature** is provided `UN` would be used to indicate `unknown` Type`. | ||
**Type Signature** can't be left blank and recommended to be added. | ||
- **Tag**: Each **TPPI content** can have a string name or tag that can help better identify the data enclosed. This would later be used for *Discovery process*. This is an *Optional field* and can be omitted in the **TPPI content**. | ||
- **Data**: The **TPPI content** encloses the data provided in *string form*, that can later be retrieved using the *Discovery process*. | ||
- The fields **Type Signature**, *(optional)* **Tag** and **Data** are separated by `~` Symbol in a **TPPI content**. | ||
|
||
**TPPI Content Processes**: | ||
|
||
- **Specify**: In this process the **Type Signature**, *(optional)* **Tag** and **Data** are joined together in **TPPI Content** form. This follows the rules for **TPPI content**. This typically happens before preparing the **TPPI packet**. | ||
- **Discover**: In this process the **Type Signature**, *(optional)* **Tag** and **Data** are recovered from the supplied **TPPI Content**. This follows the same rules for **TPPI content** in order to find the enclosed data. This is typically done after receiving the TPPI packet and getting the **TPPI contents**. | ||
|
||
**TPPI Packet Processes**: | ||
|
||
- **Assemble**: In this process the **TPPI contents** are *filtered* and *joined together* into a **TPPI packet** following respective rules. This however *should not be used* for Joining *multiple TPPI packets*. | ||
- **Disassemble**: In this process the incoming **TPPI packet** is broken into into multiple **TPPI contents** with *filtering/safeguards* removed. This however *should not be used* directly on the *Incoming TPPI packet* as *it would not be able to split apart TPPI packets*. | ||
- **Join**: This is the process of *Joining multiple packets* before sending over the **combined TPPI packets**. | ||
- **Split**: This is process perform as soon as the **TPPI packets** are received. *Only after this the process* of *Disassembly can begin*. | ||
|
||
*Background behind the name:* | ||
|
||
> The name `tppi` has been taken from a story of an imaginative kid | ||
> discovering the mysteries of the Universe and the world all around | ||
> from a remote village in the heart of Karnataka, Bharat(India). | ||
> | ||
