bolivar 1.5.1

Fast PDF content extraction, written in Rust with Python bindings

bolivar

Fast PDF text and table extraction. Written in Rust, drop-in compatible with pdfminer and pdfplumber.

Install

pip install bolivar

implementation("sa.ingenious:bolivar:1.2.0")

[dependencies]
bolivar-core = "1.2"

Extract text

Pull all text from a PDF in one call. The pdfplumber interface opens the file and iterates pages; the pdfminer interface returns the full text directly. Kotlin and Rust follow the same pattern with their respective APIs.

import pdfplumber

with pdfplumber.open("doc.pdf") as pdf:
    for page in pdf.pages:
        print(page.extract_text())

from pdfminer.high_level import extract_text

text = extract_text("doc.pdf")

import sa.ingenious.DocumentOptions
import sa.ingenious.bolivar

val doc = bolivar.open("doc.pdf", DocumentOptions {
    maxPages = 1
    layout {
        lineMargin = 0.5
        wordMargin = 0.1
    }
})
val text = doc.extractText()

use bolivar_core::high_level::extract_text;

fn main() -> bolivar_core::Result<()> {
    let data = std::fs::read("doc.pdf")?;
    let text = extract_text(&data, None)?;
    println!("{text}");
    Ok(())
}

Extract tables

Detect and extract tabular data from each page. Bolivar returns structured tables with row and column counts, bounding boxes, and cell text so you can inspect or export them without manual parsing.

import pdfplumber

with pdfplumber.open("doc.pdf") as pdf:
    for page in pdf.pages:
        for table in page.extract_tables():
            print(table)

import sa.ingenious.DocumentOptions
import sa.ingenious.bolivar

val doc = bolivar.open("doc.pdf", DocumentOptions {
    pages(1, 2)
})
val tables = doc.extractTables()
for (table in tables) {
    println("${table.rowCount}x${table.columnCount}")
}

use bolivar_core::high_level::{extract_tables_with_document, ExtractOptions};
use bolivar_core::pdfdocument::PDFDocument;
use bolivar_core::table::TableSettings;

fn main() -> bolivar_core::Result<()> {
    let data = std::fs::read("doc.pdf")?;
    let doc = PDFDocument::new(&data, "")?;
    let tables = extract_tables_with_document(
        &doc,
        ExtractOptions::default(),
        &TableSettings::default(),
    )?;
    Ok(())
}

Iterate pages

Walk through pages one at a time to read metadata like page number, dimensions, and a text preview. This is useful when you need to locate content across a large document before extracting specific pages.

import pdfplumber

with pdfplumber.open("doc.pdf") as pdf:
    for page in pdf.pages:
        print(page.page_number, page.width, page.height)

from pdfminer.high_level import extract_pages

for page in extract_pages("doc.pdf"):
    print(page.pageid, page.width, page.height)

import sa.ingenious.DocumentOptions
import sa.ingenious.bolivar

val doc = bolivar.open("doc.pdf", DocumentOptions {
    maxPages = 3
})
val pages = doc.extractPageSummaries()
for (page in pages) {
    println("${page.pageNumber}: ${page.text.take(80)}")
}

use bolivar_core::high_level::extract_pages;

fn main() -> bolivar_core::Result<()> {
    let data = std::fs::read("doc.pdf")?;
    for page in extract_pages(&data, None)? {
        let page = page?;
        println!("{}", page.pageid);
    }
    Ok(())
}

Async (Python)

Run extraction off the main thread in Python while keeping the same pdfplumber API.

import pdfplumber

async with pdfplumber.open("doc.pdf") as pdf:
    for page in pdf.pages:
        for table in page.extract_tables():
            print(table)
