FDO - Only the Solver
A finite domain constraint solver, forked from finitedomain, which in turn was originally based on FD.js.
This package only contains the solver, which only brute force solves the problem. No attempts at optimization is done here.
Part of the fdq package. See its description for a complete overview of this suite and how to run tests and all that.
Installing
npm install fdo
Usage
Find an A between 10 and 20 that are bigger than 14 and smaller than 17 and not 16. Contrived? Nah.
import FDO from 'fdo';
let solution = FDO.solve(`
: A [10 20]
A > 14
A < 17
A != 16
`);
console.log(solution); // -> {A: 15}
For the DSL syntax see the docs in fdq.
Tasks
There are a few grunt tasks and bash scripts hooked up to npm. This repo also uses git hooks for pre- and post commit hooks.
As a general rule, ./build
is used for any temporary output, including code coverage reports and temporary build files when producing a dist.
Then ./dist
only contains final builds (./dist/fdo.dist.min.js
and for some tasks ./dist/fdo.js
).
Note that both ./build
and ./dist
are cleared at the start of almost every (grunt) task.
(These tasks obviously require an npm install
)
Grunt tasks:
grunt clean
: removes./dist
and./build
grunt build
: a direct alias fordist
grunt dist
: lint, test, build, and minify to produce a real dist buildgrunt distq
: create a dist but skip linting, testing, and code coverage. Also produces a copy in./dist/fdp.js
grunt distbug
: creates a build without removing test artifacts or minification. In case you need proper stack traces in other projects.grunt distheat
: creates a dist but instead of minification as the last step it beautifies. Used for HeatFiler, a count based heatmap profiler. Copies tofdp.js
.grunt coverage
: runs all tests in the code coverage toolgrunt test
: runs linting and all testsgrunt testq
: runs tests without lintinggrunt testtb
: testq but fail fastgrunt watch:q
: runsdistq
whenever a file changesgrunt watch:h
: runsdistheat
whenever a file changesgrunt watch:b
: runsdistbug
whenever a file changesgrunt watch:t
: runstestq
whenever a file changesgrunt watch:tb
: runstesttb
whenever a file changes
Bash / npm scripts:
npm run lint
: run eslint with dist config (slightly stricter than dev). Exits non-zero if it fails.npm run lintdev
: run eslint with dev config (allowsconsole.log
,debugger
, etc). No non-zero exit for failures.npm run lintfix
: runs eslint in the fix mode
