## Upgrade from `v2.x` to `v3.x`
|
||||
|
||||
With the release of `v3.0.0` the bot changed a lot introducing a new storage format. As that storage backend is not compatible with the `v2.x` storage you need to migrate it manually before starting a `v3.x` bot version the first time.
|
||||
|
||||
**Before starting the migration make sure to fully stop the bot!**
|
||||
|
||||
This section assumes you were starting your `v2.x` bot the following way:
|
||||
|
||||
```console
|
||||
# twitch-bot \
|
||||
--storage-file storage.json.gz
|
||||
--twitch-client <clientid> \
|
||||
--twitch-client-secret <secret>
|
||||
```
|
||||
|
||||
To execute the migration we need to provide the same `storage-encryption-pass` or `twitch-client` / `twitch-client-secret` combination if no `storage-encryption-pass` was used.
|
||||
|
||||
```console
|
||||
# twitch-bot \
|
||||
--storage-conn-type <database type> \
|
||||
--storage-conn-string <database connection string> \
|
||||
--twitch-client <clientid> \
|
||||
--twitch-client-secret <secret> \
|
||||
migrate-v2 storage.json.gz
|
||||
WARN[0000] No storage encryption passphrase was set, falling back to client-id:client-secret
|
||||
WARN[0000] Module registered unhandled query-param type module=status type=integer
|
||||
WARN[0000] Overlays dir not specified, no dir or non existent dir=

||||

|
||||
INFO[0000] Starting migration... module=timers
|
||||
INFO[0000] v2 storage file was migrated
|
||||
```
|
||||
|
||||
If you see the `v2 storage file was migrated` message the contents of your old storage file were migrated to the new database. The old file is not modified in this step.
|
||||
|
||||
Afterwards your need to adjust the start parameters of the bot:
|
||||
|
||||
```console
|
||||
# twitch-bot \
|
||||
--storage-conn-type <database type> \
|
||||
--storage-conn-string <database connection string> \
|
||||
--twitch-client <clientid> \
|
||||
--twitch-client-secret <secret> \
|
||||
```

## Upgrade from `v2.x` to `v3.x`
|
||||
|
||||
When adding [sprig](https://masterminds.github.io/sprig/) function collection some functions collided and needed replacement. You need to adapt your templates accordingly:
|
||||
|
||||
- Math functions (`add`, `div`, `mod`, `mul`, `multiply`, `sub`) were replaced with their sprig-equivalent and are now working with integers instead of floats. If you need them to continue to work with floats you need to use their [float-variants](https://masterminds.github.io/sprig/mathf.html).
|
||||
- `now` does no longer format the current date as a string but return the current date. You need to replace this: `now "2006-01-02"` becomes `now | date "2006-01-02"`.
|
||||
- `concat` is now used to concat arrays. To join strings you will need to modify your code: `concat ":" "string1" "string2"` becomes `lists "string1" "string2" | join ":"`.
|
||||
- `toLower` / `toUpper` need to be replaced with their sprig equivalent `lower` and `upper`.

## Upgrade from `v2.x` to `v3.x`
|
||||
|
||||
When adding [sprig](https://masterminds.github.io/sprig/) function collection some functions collided and needed replacement. You need to adapt your templates accordingly:
|
||||
|
||||
- Math functions (`add`, `div`, `mod`, `mul`, `multiply`, `sub`) were replaced with their sprig-equivalent and are now working with integers instead of floats. If you need them to continue to work with floats you need to use their [float-variants](https://masterminds.github.io/sprig/mathf.html).
|
||||
- `now` does no longer format the current date as a string but return the current date. You need to replace this: `now "2006-01-02"` becomes `now | date "2006-01-02"`.
|
||||
- `concat` is now used to concat arrays. To join strings you will need to modify your code: `concat ":" "string1" "string2"` becomes `lists "string1" "string2" | join ":"`.
|
||||
- `toLower` / `toUpper` need to be replaced with their sprig equivalent `lower` and `upper`.
