Flaggy is here to help with flags
Flaggy is a CLI tool used for generation of settings and feature flags for applications that use environment variables to operate - for example with 12 factor app principles.
Usage
$ cargo build --release
./target/release/flaggy --flags-file flags/lucy.yml
Will take the given YAML file (that can also be found here):
flags:
ENV:
- staging
- production
- development
FLAG_A: "a"
FLAG_B: [ b,c ]
FLAG_C: "https://epic.blog"
FLAG_D: [ true, false ]And will generate the following output (permutation of all flags):
ENV=staging;FLAG_A=a;FLAG_B=b;FLAG_C=https://epic.blog;FLAG_D=true
ENV=staging;FLAG_A=a;FLAG_B=b;FLAG_C=https://epic.blog;FLAG_D=false
ENV=staging;FLAG_A=a;FLAG_B=c;FLAG_C=https://epic.blog;FLAG_D=true
ENV=staging;FLAG_A=a;FLAG_B=c;FLAG_C=https://epic.blog;FLAG_D=false
ENV=production;FLAG_A=a;FLAG_B=b;FLAG_C=https://epic.blog;FLAG_D=true
