Mat3ra Regex.

regex

Usage

1. Install package adding to package.json:

   "dependencies": {
       "@exabyte-io/regex": "2023.9.1"
   }
   

Or using npm: bash npm i @exabyte-io/regex@2023.9.1

2. Import package:

   import regexSchemas from "@exabyte-io/regex/lib/schemas";
   

3. Use regex schemas:

   const calculationPattern = regexSchemas.espresso["5.2.1"]["pw.x"]["stdin"].calculation;
   const regex = new RegExp(calculationPattern.regex, calculationPattern.flags.join("));
   

Development

To run tests:

npm test

To run lint:

npm run lint

To build regex schemas for development:

npm run build:schemas:dev

Add new regex schemas

1. Add new yamls for stdin and stdout to assets/file/applications/<application_name>/<application_version>/<unit_name>/
2. Run npm run build:schemas:dev to generate new regex schemas for dev
3. Add tests for newly added regex schemas

Usage

1. Install dependency (list in package.json ar with npm install):

npm install @exabyte-io/regex

2. Import schema.json with compiled regexes in your code:

import regexesSchema from "@exabyte-io/regex/data/schemas.json"

3. Use regexesSchema object to found needed regex based on application and version for example (you can use json-pointer to get needed path):

import pointer from "json-pointer";

const espressoNamelistRegex = pointer.get(
    schemas,
    "/applications/espresso/5.2.1/pw.x/stdin/control/_format",
);

// _format contains regex with template string
// available templates for regex should be enumerated in params section
// name of param define template string to replace
// possible values will be enumerated as value of param
// "params":{"BLOCK_NAME":["CONTROL","ELECTRONS","IONS","CELL","SYSTEM"]}

const controlBlockRegex = new RegExp(
    espressoNamelistRegex.regex.replace('{{BLOCK_NAME}}', 'CONTROL'),
    espressoNamelistRegex.flags.join(""),
);

// getting namelist blocks
const controlBlocksMatch = file.match(controlBlockRegex);
const controlBlock = controlBlocksMatch[0];


const regexObject = pointer.get(
    schemas,
    "/applications/espresso/5.2.1/pw.x/stdin/control/calculation",
);
const regexCalculation = new RegExp(
    regexObject.regex,
    regexObject.flags.join(""),
);

// getting calculation param value
const calculation = controlBlock.matchAll(regexCalculation);
const [calcluationLine, calculationValue] = Array.from(calculation)[0];


console.log({ calcluationLine, calculationValue })
