CEL Policy Compiler
Policies which use CEL often evolve to express complex logic using multiple statements
and decision criteria. The CEL Policy Compiler provides an extensible format for parsing,
compiling, and composing expression graphs. Below is a simple example which can easily
be compiled to a single CEL expression.
name: "my-policy"
rule:
variables:
- name: greeting
expression: "'%s, %s!'"
- name: people
expression: >
['Tristan', 'Calla', 'Antoine', 'Jonathan', 'Sokwhan', 'Rebecca']
match:
- condition: "request.user in variables.people"
output: "variables.greeting.format(['hello', request.user])"
- output: "variables.greeting.format(['goodbye', 'stranger'])"- Simple Policy Compiler [#924]
- Introduce protobuf message testing to policies [#961]
- Generate policy explanations during compilation [#977]
- Variable and nested rule limits [#989]
- Improved support for nested rules #991]
Fixes

exists_onemacro [#935] - Avoid iterating over the source multiple times during parse [#936]
- Fix for working with byte arrays by [#958]
- Stabilize macro id generation during optimization [#962]
- String formatting panic fix for non-literal format strings [#987]
- Add nil checking for wrapperspb's types [#960]
- Prevent self-append for
Issues[#988] - Use bytes interface value for zero native type struct fields instead of dynamic list [#981]
Presence Test Semantics
The following two changes identified an issue where presence test was unexpectedly being performed over a scalar type and evaluating to absent rather than erroring. It is strongly advised to set the flag cel.EnableErrorOnBadPresenceTest(true) to avoid a logical correctness issue.
- Fix presence test to produce an error when it's not a map or a message [#922]
- Update the presence testing fix to be opt-out [#939]
Deprecation Cleanup
- Remove the deprecated protobuf function and type declarations [#921]
