Write once, run against any conforming dataset.\n\n## File Types\n\n\u003e **_NOTE:_** Only `.csv` files are supported for now.\n\n| Extension | Purpose                                  |\n| --------- | ---------------------------------------- |\n| `.eli`    | Source code                              |\n| `.elt`    | Schema / type definitions for input data |\n| `.csv`    | Input data file                          |\n| `.elc`    | Generated file with compiled bytecode    |\n\n## Execution Modes\n\n### 1. Safe Direct Execution\n\n```bash\nelise --mode=run --source-code=sample.eli --data=data.csv --data-schema=data.elt\n```\n\n- Compiles in-memory (no `.elc` output)\n\n- Performs full runtime validation of input data against schema\n\n- Executes immediately\n\n**Safety**: High\n\n### 2. Unsafe Execution (Maximum Performance)\n\nStep 1 — Build an executable\n\n```bash\nelise --mode=build --source-code=sample.eli --data-schema=data.elt --output=program.elc\n```\n\nStep 2 — Execute\n\n```bash\nelise --mode=exec --executable=program.elc --data=data.csv\n```\n\n- Requires precompiled .elc\n\n- Skips runtime validation\n\n- Executes fastest possible path\n\n**Use case**: trusted, prevalidated data\n\n**Safety**: None ⚠️\n\n### 3. Validation-Only Step\n\n```bash\nelise --mode=validate --data=data.csv --data-schema=data.elt\n```\n\n- Full scan of data to ensure strict schema compliance\n\n- Can be used before unsafe execution\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzavvdev%2Felise-lang","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fzavvdev%2Felise-lang","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzavvdev%2Felise-lang/lists"}
