Documentation
Add and remove facts, entities, variables, constraints, scores, solutions, and demo data in generated SolverForge apps.
Generator Commands
Generator commands synchronize Rust domain files, app metadata, and generated
frontend model files. They expect the current project to retain the managed
@solverforge:begin ... / @solverforge:end ... regions emitted by the
current scaffold.
solverforge generate
solverforge generate [OPTIONS] <COMMAND>
Subcommands:
| Subcommand | Purpose |
|---|---|
constraint |
Add a constraint skeleton to src/constraints/ |
entity |
Add a planning entity struct in src/domain/ |
fact |
Add a problem fact struct in src/domain/ |
solution |
Add or replace the neutral planning solution struct |
variable |
Add a scalar or list planning variable to an existing entity |
score |
Change the score type in the existing planning solution |
data |
Regenerate compiler-owned demo data from the project model |
generate fact
solverforge generate fact [OPTIONS] <NAME>
| Option | Meaning |
|---|---|
--field <NAME:TYPE> |
Add a repeatable extra Rust field |
-f, --force |
Overwrite the fact file if it already exists |
--pretend |
Preview changes without writing files |
Creates src/domain/<name>.rs, updates src/domain/mod.rs, wires the
collection into the planning solution, and syncs solverforge.app.toml plus the
generated UI model.
solverforge generate fact employee --field "skill:String"
generate entity
solverforge generate entity [OPTIONS] <NAME>
| Option | Meaning |
|---|---|
--planning-variable <FIELD> |
Add an optional scalar planning-variable placeholder |
--field <NAME:TYPE> |
Add a repeatable extra Rust field |
-f, --force |
Overwrite the entity file if it already exists |
--pretend |
Preview changes without writing files |
--planning-variable emits #[planning_variable(allows_unassigned = true)]
with an Option<usize> field. Use generate variable when you need an explicit
scalar range or list element collection.
solverforge generate entity shift --planning-variable employee_idx
generate variable
solverforge generate variable [OPTIONS] --entity <ENTITY_TYPE> --kind <KIND> <FIELD>
| Option | Meaning |
|---|---|
--entity <ENTITY_TYPE> |
Target entity struct name, such as Shift |
--kind <KIND> |
Variable kind; valid values are scalar and list |
--range <FACT_COLLECTION> |
Required for --kind scalar; source fact collection |
--elements <FACT_COLLECTION> |
Required for --kind list; list element collection |
--allows-unassigned |
Scalar only; generate an optional assignment |
standard is not a variable kind. It is only the default demo data size label
used by solverforge.app.toml.
solverforge generate variable employee_idx --entity Shift --kind scalar --range employees --allows-unassigned
solverforge generate variable stops --entity Route --kind list --elements visits
generate constraint
solverforge generate constraint [OPTIONS] <NAME>
Hardness options:
| Option | Meaning |
|---|---|
--hard |
Hard constraint; this is the default for hard-capable patterns |
--soft |
Soft constraint |
Pattern options:
| Option | Meaning |
|---|---|
--unary |
Penalize matching entities with for_each + filter + penalize |
--pair |
Penalize conflicting pairs with pairwise comparison |
--join |
Penalize entity-fact mismatch with for_each + join |
--balance |
Generate a load-balance style soft constraint |
--reward |
Reward matching entities with for_each + filter + reward |
Write options:
| Option | Meaning |
|---|---|
-f, --force |
Overwrite the constraint file if it already exists |
--pretend |
Preview changes without writing files |
Choose at most one pattern flag. If no pattern flag is supplied, the command
scans the current domain and opens an interactive wizard. --balance and
--reward imply soft scoring in the current generator.
solverforge generate constraint max_hours --unary --hard
solverforge generate constraint no_overlap --pair
solverforge generate constraint required_skill --join --hard
generate solution
solverforge generate solution [OPTIONS] <NAME>
| Option | Meaning |
|---|---|
--score <SCORE_TYPE> |
Score type; default HardSoftScore |
A fresh neutral scaffold can be replaced once by this command. If the project is already shaped, destroy the existing solution first.
solverforge generate solution schedule --score HardSoftScore
generate score
solverforge generate score [OPTIONS] <SCORE_TYPE>
<SCORE_TYPE> can be HardSoftScore, HardSoftDecimalScore,
HardMediumSoftScore, SoftScore, SimpleScore, or a concrete bendable score
such as BendableScore<2, 3>.
solverforge generate score HardSoftDecimalScore
generate data
solverforge generate data [OPTIONS]
| Option | Meaning |
|---|---|
--mode <MODE> |
Data generation mode; valid values are sample and stub; default sample |
--size <SIZE> |
Default demo size; valid values are small, standard, and large |
The command rewrites src/data/data_seed.rs, ensures the stable
src/data/mod.rs wrapper exists, and updates [demo].default_size in
solverforge.app.toml when --size is provided.
solverforge generate data
solverforge generate data --size large
solverforge generate data --mode stub
solverforge destroy
solverforge destroy [OPTIONS] <COMMAND>
Removes generated resources and resyncs the app spec and UI model. The
confirmation flag belongs to the destroy command itself, so place it before
the resource subcommand.
| Option | Meaning |
|---|---|
-y, --yes |
Skip the confirmation prompt |
Subcommands:
| Subcommand | Usage | Purpose |
|---|---|---|
solution |
solverforge destroy [OPTIONS] solution |
Remove the planning solution struct |
entity |
solverforge destroy [OPTIONS] entity <NAME> |
Remove a planning entity and unwire its solution collection |
variable |
solverforge destroy [OPTIONS] variable --entity <ENTITY_TYPE> <FIELD> |
Remove a planning variable field from an entity |
fact |
solverforge destroy [OPTIONS] fact <NAME> |
Remove a problem fact and unwire its solution collection |
constraint |
solverforge destroy [OPTIONS] constraint <NAME> |
Remove a constraint module and registry entry |
solverforge destroy entity shift
solverforge destroy --yes constraint no_overlap
solverforge destroy -y variable --entity Task resource_idx
