# Developing
Notes for managing and internal development
## Transforms
Transforms are data structures within rules which will be integrated into other fields at build
time for rules, meaning they are not directly converted.
### CLI
There are some helper commands to assist with converting transforms into the excpected rule TOML format
- create transform in Kibana
- export it (or copy it)
- run the following commmand and paste them (multiple)
- copy and paste into rule, with minor format changes if needed
```console
(detection_dev) ➜ detection-rules git:(initial_inv_queries) python -m detection_rules dev transforms guide-plugin-convert

[transform]
[[transform.investigate]]
label = "Alerts associated with the host in the last 48h"
providers = [[{field = "event.kind", excluded = false, queryType = "phrase", value = "signal", valueType = "string"}, {field = "host.name", excluded = false, queryType = "phrase", value = "{{host.name}}", valueType = "string"}]]
relativeFrom = "now-48h/h"
relativeTo = "now"
```
Other transform suppoprt can be found under
`python -m detection-rules dev transforms -h`
## Using the `RuleResource` methods built on detections `_bulk_action` APIs
The following is meant to serve as a simple example of to use the methods
```python
import kibana
from kibana import definitions
rids = ['40e1f208-aaaa-bbbb-98ea-378ccf504ad3', '5e9bc07c-cccc-dddd-a6c0-1cae4a0d256e']
# with TypedDict, either is valid, both with static type checking
set_tags = definitions.RuleBulkSetTags(type='set_tags', value=['tag1', 'tag2'])
delete_tags: definitions.RuleBulkDeleteTags = {'type': 'delete_tags', 'value': ['tag1', 'tag2']}
with kibana:
r1 = RuleResource.bulk_enable(rids, dry_run=True)
r2 = RuleResource.bulk_disable(rids, dry_run=True)
r3 = RuleResource.bulk_duplicate(rids, dry_run=True)
r4 = RuleResource.bulk_export(rids)
r5 = RuleResource.bulk_edit(edit_object=[set_tags, delete_tags], rule_ids=rids, dry_run=True)
r6 = RuleResource.bulk_delete(rids, dry_run=True)
```
