# ciclostile
Fill .docx templates: replace text, insert images and tables, and keep everything else untouched.
Open a Word document, replace placeholders such as `{{name}}` with
text, an image or a table, and write the result. ciclostile doesn't model
the document: it finds the placeholders in the XML and edits it in
place, so whatever else the template holds - styles, numbering, fields,
comments, tracked changes, embedded objects - comes out as it went in.
That is meant literally: parts that no replacement touches are copied
without being re-serialized, and in a part that is edited, every byte
of XML the edit doesn't need to change stays as it was.
*Ciclostile* (/tʃikloˈstiːle/) is Italian for *mimeograph*.
## Quick start
Open the template, fill in its placeholders and write the result. The
[`fill_template`](examples/fill_template.rs) example does the same from
the command line.
```rust
use ciclostile::{Docx, Image, Length, Table};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut docx = Docx::from_bytes(std::fs::read("template.docx")?)?;
docx.replace_text([
("{{customer}}", "Ada Lovelace"),
("{{date}}", "3 November 2026"),
("{{address}}", "12 St James's Square\nLondon"),
]);
let logo = Image::from_bytes(std::fs::read("logo.png")?)?.width(Length::from_cm(4.0));
docx.replace_with_image("{{logo}}", &logo);
let items = Table::new([
["Item", "Quantity"],
["Analytical engine", "1"],
["Punched cards", "500"],
])
.header(true);
docx.replace_with_table("{{items}}", &items)?;
std::fs::write("output.docx", docx.to_bytes())?;
Ok(())
}
```
