# Digital Employee Runbook
This file is the minimal operating contract for calling `docfill` from a digital employee, scheduler, or shell script.
## Inputs
Each run needs:
- A `task.json` config file.
- A data source: `.xlsx` or SQLite `.db`.
- Optional business filters in `filter.equals`.
- A template: `.docx` or `.xlsx`.
- An output path pattern in `task.json`.
Paths inside `task.json` are resolved from the config file directory.
Use one `task.json` per business task. Use `--var` for values that change per run, such as date, ticket number, person, or batch.
## Command
```bash
docfill run -c /path/to/task.json --var date=2026-06-18
```
Use repeated `--var key=value` arguments for runtime values:
```bash
docfill run -c task.json --var date=2026-06-18 --var ticket_no=GD-002
```
Priority:
```text
row data > CLI --var > task.json vars
```
CLI variables override `vars` in `task.json`. The selected row data overrides both when rendering templates and output paths.
If `task.json` has a filter:
```json
"filter": {
"equals": {
"日期": "{{date}}",
"工单编号": "{{ticket_no}}"
},
"expect": "one"
}
```
then the command:
```bash
docfill run -c task.json --var date=2026-06-18 --var ticket_no=GD-002
```
selects the row where `日期 = 2026-06-18` and `工单编号 = GD-002`.
Use `--verbose` only when diagnosing a failed or suspicious run:
```bash
docfill run -c task.json --var date=2026-06-18 --var ticket_no=GD-002 --verbose
```
## Success
Exit code `0`.
Stdout contains generated files:
```text
generated 2 file(s)
- /path/to/out/report_张三.xlsx
- /path/to/out/report_李四.xlsx
```
## Failure
Exit code `1` means the task ran but failed.
Exit code `2` means the command line was invalid.
Errors are written to stderr with the `docfill:` prefix:
```text
docfill: [TEMPLATE_FIELD_MISSING] render row 1: missing template field "done"
hint: Add column "done" to the data source or pass --var done=...
context: field=done template=/path/template.docx
```
Verbose logs are also written to stderr:
```text
log: load config path=/path/task.json
log: read data type=excel path=/path/data.xlsx
log: read data type=excel path=/path/data.xlsx rows=3
log: filter rows=3 matched=1 expect=one
log: render row=1 output=/path/out/work_order_2026-06-18_GD-002.docx
```
## Error Codes
`CLI_USAGE`
The command line is invalid.
`CONFIG_READ`
The config file cannot be read.
`CONFIG_PARSE`
The config file is not valid JSON.
`CONFIG_VALIDATE`
The config is missing required fields or uses unsupported values.
`DATA_EXCEL`
Excel data cannot be opened or read.
`DATA_SQLITE`
SQLite data cannot be opened, queried, or parameterized.
`DATA_EMPTY`
The data source returned no rows.
`DATA_FILTER_FIELD`
The filter references a field that is not in the data.
`DATA_FILTER_VALUE`
The filter references a variable that was not provided.
`DATA_FILTER_NO_MATCH`
The filter matched no rows.
`DATA_FILTER_MULTI_MATCH`
The filter expected one row but matched multiple rows.
`TEMPLATE_OPEN`
The template file cannot be opened or inspected.
`TEMPLATE_FIELD_MISSING`
The template references a field that is not available.
`TEMPLATE_UNRESOLVED`
The rendered file would still contain a `{{field}}` placeholder.
`OUTPUT_EXISTS`
The output file exists and overwrite is not enabled.
`OUTPUT_WRITE`
The output directory or file cannot be written.
`INTERNAL`
An unexpected unclassified error occurred.
## Common Errors
`missing template field`
The template contains a `{{field}}` that is not present in data, `vars`, or CLI `--var`.
`output already exists`
The output file exists and `output.overwrite` is not `true`.
`missing sqlite params field`
A SQLite query parameter such as `{{date}}` was not provided.
`filter matched no rows`
Check `filter.equals`, `--var` values, or the source table contents.
`filter matched N rows but expected one`
Add another filter condition or clean duplicate rows in the source table.
`filter field is not in data`
Check Excel headers or SQLite query column names.
`unresolved placeholder`
The rendered document still contains `{{field}}`. Check the source data value and the template.
## Build
```bash
bash scripts/build.sh
```
The local build output is:
```text
dist/docfill-darwin-arm64
```
## Smoke Test
```bash
bash scripts/smoke.sh
```
Smoke test builds a temporary binary, generates temporary example files, runs example configs including the filter case, and checks generated outputs.
