# minimax-docx

Create, edit, and format DOCX documents via CLI tools or direct C# scripts built on OpenXML SDK (.NET).

## Setup

**First time:** `bash scripts/setup.sh` (or `powershell scripts/setup.ps1` on Windows, `--minimal` to skip optional deps).

**First operation in session:** `scripts/env_check.sh` — do not proceed if `NOT READY`. (Skip on subsequent operations within the same session.)

## Quick Start: Direct C# Path

When the task requires structural document manipulation (custom styles, complex tables, multi-section layouts, headers/footers, TOC, images), write C# directly instead of wrestling with CLI limitations. Use this scaffold:

```csharp
// File: scripts/dotnet/task.csx  (or a new .cs in a Console project)
// dotnet run --project scripts/dotnet/MiniMaxAIDocx.Cli -- run-script task.csx
#r "nuget: DocumentFormat.OpenXml, 3.2.0"

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;

using var doc = WordprocessingDocument.Create("output.docx", WordprocessingDocumentType.Document);
var mainPart = doc.AddMainDocumentPart();
mainPart.Document = new Document(new Body());

// --- Your logic here ---
// Read the relevant Samples/*.cs file FIRST for tested patterns.
// See Samples/ table in References section below.
```

**Before writing any C#, read the relevant `Samples/*.cs` file** — they contain compilable, SDK-version-verified patterns. The Samples table in the References section below maps topics to files.

## CLI shorthand

All CLI commands below use `$CLI` as shorthand for:
```bash
dotnet run --project scripts/dotnet/MiniMaxAIDocx.Cli --
```

## Pipeline routing

Route by checking: does the user have an input .docx file?

```
User task
├─ No input file → Pipeline A: CREATE
│   signals: "write", "create", "draft", "generate", "new", "make a report/proposal/memo"
│   → Read references/scenario_a_create.md
│
└─ Has input .docx
    ├─ Replace/fill/modify content → Pipeline B: FILL-EDIT
    │   signals: "fill in", "replace", "update", "change text", "add section", "edit"
    │   → Read references/scenario_b_edit_content.md
    │
    └─ Reformat/apply style/template → Pipeline C: FORMAT-APPLY
        signals: "reformat", "apply template", "restyle", "match this format", "套模板", "排版"
        ├─ Template is pure style (no content) → C-1: OVERLAY (apply styles to source)
        └─ Template has structure (cover/TOC/example sections) → C-2: BASE-REPLACE
            (use template as base, replace example content with user content)
        → Read references/scenario_c_apply_template.md
```

If the request spans multiple pipelines, run them sequentially (e.g., Create then Format-Apply).

## Pre-processing

Convert `.doc` → `.docx` if needed: `scripts/doc_to_docx.sh input.doc output_dir/`

Preview before editing (avoids reading raw XML): `scripts/docx_preview.sh document.docx`

Analyze structure for editing scenarios: `$CLI analyze --input document.docx`

## Scenario A: Create

Read `references/scenario_a_create.md`, `references/typography_guide.md`, and `references/design_principles.md` first. Pick an aesthetic recipe from `Samples/AestheticRecipeSamples.cs` that matches the document type — do not invent formatting values. For CJK, also read `references/cjk_typography.md`.

**Choose your path:**
- **Simple** (plain text, minimal formatting): use CLI — `$CLI create --type report --output out.docx --config content.json`
- **Structural** (custom styles, multi-section, TOC, images, complex tables): write C# directly. Read the relevant `Samples/*.cs` first.

Then run the **validation pipeline** (below).

## Scenario B: Edit / Fill

Read `references/scenario_b_edit_content.md` first. Preview → analyze → edit → validate.

**Choose your path:**
- **Simple** (text replacement, placeholder fill): use CLI subcommands.
- **Structural** (add/reorganize sections, modify styles, manipulate tables, insert images): write C# directly. Read `references/openxml_element_order.md` and the relevant `Samples/*.cs`.

Available CLI edit subcommands:
- `replace-text --find "X" --replace "Y"`
- `fill-placeholders --data '{"key":"value"}'`
- `fill-table --data table.json`
- `insert-section`, `remove-section`, `update-header-footer`

```bash
$CLI edit replace-text --input in.docx --output out.docx --find "OLD" --replace "NEW"
$CLI edit fill-placeholders --input in.docx --output out.docx --data '{"name":"John"}'
```

Then run the **validation pipeline**. Also run diff to verify minimal changes:
```bash
$CLI diff --before in.docx --after out.docx
```

## Scenario C: Apply Template

Read `references/scenario_c_apply_template.md` first. Preview and analyze both source and template.

```bash
$CLI apply-template --input source.docx --template template.docx --output out.docx
```

For complex template operations (multi-template merge, per-section headers/footers, style merging), write C# directly — see Critical Rules below for required patterns.

Run the **validation pipeline**, then the **hard gate-check**:
```bash
$CLI validate --input out.docx --gate-check assets/xsd/business-rules.xsd
```
Gate-check is a **hard requirement**. Do NOT deliver until it passes. If it fails: diagnose, fix, re-run.

Also diff to verify content preservation: `$CLI diff --before source.docx --after out.docx`

## Validation pipeline

Run after every write operation. For Scenario C the full pipeline is **mandatory**; for A/B it is **recommended** (skip only if the operation was trivially simple).

```bash
$CLI merge-runs --input doc.docx                                    # 1. consolidate runs
$CLI validate --input doc.docx --xsd assets/xsd/wml-subset.xsd     # 2. XSD structure
$CLI validate --input doc.docx --business                           # 3. business rules
```

If XSD fails, auto-repair and retry:
```bash
$CLI fix-order --input doc.docx
$CLI validate --input doc.docx --xsd assets/xsd/wml-subset.xsd
```

If XSD still fails, fall back to business rules + preview:
```bash
$CLI validate --input doc.docx --business
scripts/docx_preview.sh doc.docx
# Verify: font contamination=0, table count correct, drawing count correct, sectPr count correct
```

Final preview: `scripts/docx_preview.sh doc.docx`

## Critical rules

These prevent file corruption — OpenXML is strict about element ordering.

**Element order** (properties always first):

| Parent | Order |
|--------|-------|
| `w:p`  | `pPr` → runs |
| `w:r`  | `rPr` → `t`/`br`/`tab` |
| `w:tbl`| `tblPr` → `tblGrid` → `tr` |
| `w:tr` | `trPr` → `tc` |
| `w:tc` | `tcPr` → `p` (min 1 `<w:p/>`) |
| `w:body` | block content → `sectPr` (LAST child) |

**Direct format contamination:** When copying content from a source document, inline `rPr` (fonts, color) and `pPr` (borders, shading, spacing) override template styles. Always strip direct formatting — keep only `pStyle` reference and `t` text. Clean tables too (including `pPr/rPr` inside cells).

**Track changes:** `<w:del>` uses `<w:delText>`, never `<w:t>`. `<w:ins>` uses `<w:t>`, never `<w:delText>`.

**Font size:** `w:sz` = points × 2 (12pt → `sz="24"`). Margins/spacing in DXA (1 inch = 1440, 1cm ≈ 567).

**Heading styles MUST have OutlineLevel:** When defining heading styles (Heading1, ThesisH1, etc.), always include `new OutlineLevel { Val = N }` in `StyleParagraphProperties` (H1→0, H2→1, H3→2). Without this, Word sees them as plain styled text — TOC and navigation pane won't work.

**Multi-template merge:** When given multiple template files (font, heading, breaks), read `references/scenario_c_apply_template.md` section "Multi-Template Merge" FIRST. Key rules:
- Merge styles from all templates into one styles.xml. Structure (sections/breaks) comes from the breaks template.
- Each content paragraph must appear exactly ONCE — never duplicate when inserting section breaks.
- NEVER insert empty/blank paragraphs as padding or section separators. Output paragraph count must equal input. Use section break properties (`w:sectPr` inside `w:pPr`) and style spacing (`w:spacing` before/after) for visual separation.
- Insert oddPage section breaks before EVERY chapter heading, not just the first. Even if a chapter has dual-column content, it MUST start with oddPage; use a second continuous break after the heading for column switching.
- Dual-column chapters need THREE section breaks: (1) oddPage in preceding para's pPr, (2) continuous+cols=2 in the chapter HEADING's pPr, (3) continuous+cols=1 in the last body para's pPr to revert.
- Copy `titlePg` settings from the breaks template for EACH section. Abstract and TOC sections typically need `titlePg=true`.

**Multi-section headers/footers:** Templates with 10+ sections (e.g., Chinese thesis) have DIFFERENT headers/footers per section (Roman vs Arabic page numbers, different header text per zone). Rules:
- Use C-2 Base-Replace: copy the TEMPLATE as output base, then replace body content. This preserves all sections, headers, footers, and titlePg settings automatically.
- NEVER recreate headers/footers from scratch — copy template header/footer XML byte-for-byte.
- NEVER add formatting (borders, alignment, font size) not present in the template header XML.
- Non-cover sections MUST have header/footer XML files (at least empty header + page number footer).
- See `references/scenario_c_apply_template.md` section "Multi-Section Header/Footer Transfer".

## References

Load as needed — don't load all at once. Pick the most relevant files for the task.

**The C# samples and design references below are the project's knowledge base ("encyclopedia").** When writing OpenXML code, ALWAYS read the relevant sample file first — it contains compilable, SDK-version-verified patterns that prevent common errors. When making aesthetic decisions, read the design principles and recipe files — they encode tested, harmonious parameter sets from authoritative sources (IEEE, ACM, APA, Nature, etc.), not guesses.
