Quillo plugins
628 plugins, one Rust file each
What the standard library leaves out, in Rust: CSV, Excel, YAML and XML, tokens and two-factor codes, QR codes and PDFs, Redis, S3 and email. Each one is a .qwer file beside your program: use it, and its functions are yours, checked by quillo check and fast as Rust. Every plugin here is built and its example run before the site is published.

quillo install csv. The.qwerfile is the whole plugin; the command checks its version and its hash against the catalog. useit, as you use a.qwefile. Its functions are then the program's, andquillo checkknows their types.- Run the program. The first run builds the plugin with
cargo, which takes a while the first time; later runs load what was built.
$ quillo install csv # csv.qwer, version and hash checked$ quillo install csv qr jwt # several at once$ quillo install --list # what there ismain.qwe
import csv use csv_write // only what you use; use csv.qwer takes them allroute GET /orders.csv = csv_write(orders(), ["id", "customer", "total"])?The machine that builds a plugin needs Rust. The server it runs on does not: quillo build main.qwe builds every plugin the program uses into .quillo/native/, which you deploy with the program, built on the same system as the server. Plugins run on the server, off the event loop; components call them through a server fn.

A .qwer file is ordinary Rust: its pub fns are Quillo functions, and its //! [dependencies] lines are its crates, from crates.io or git. Values cross as Quillo has them (text, numbers, lists, maps), and a Result is a value or an error value. The Rust page has the rules; any plugin here is a starting point.
