In Ring 1.27 (GitHub) - Faster WebLib - HTML generation using nested braces (78x faster)

[Mahmoud Fayed]

Hello

Ring 1.27 introduces a major performance improvement to the WebLib library through a new stack-based rendering engine for nested HTML elements. In previous versions, every HTML element created inside a brace block — such as Table, TR, TD, H1, and so on — allocated a separate Ring object in memory. A page with a table of 100 rows and 5 columns would silently create over 500 objects, each carrying hundreds of attributes, output string, and child object list. The overhead of allocating, initializing, and garbage-collecting all these objects was the dominant cost of page generation.

Example:

load "weblib.ring" import system.web func main t1 = clock() cOutput = createReport() t2 = clock() ? "Time: " + (t2-t1) + " ms" write("report.html", cOutput) system("report.html") func createReport nCustCount = 100 oPage = new HtmlPage { h1 { text("Customers Report") } Table { style = styleWidth("100%")+styleGradient(4) TR { TD { WIDTH = "10%" text("Customers Count : ") } TD { text(nCustCount) } } } Table { style = styleWidth("100%")+styleGradient(26) TR { style = styleWidth("100%")+styleGradient(24) TD { text("Name ") } TD { text("Age") } TD { text("Country") } TD { text("Job") } TD { text("Company") } } for t=1 to nCustCount TR { TD { text("Test "+t) } TD { text("30") } TD { text("Egypt") } TD { text("Sales") } TD { text("Future") } } next } } return oPage.output()

Output (Using Ring 1.27):

Time: 9 ms

Output (Using Ring 1.26):

Time: 703 ms

Ring 1.27 completes in 9 ms versus 703 ms in Ring 1.26 — a ~78x faster.

Pages with deeper nesting or more rows benefit proportionally. Existing user code requires no changes; the brace-block syntax, attribute assignment, style functions, and all element names work exactly as before.

Note: If we need better performance, we can generate HTML documents using WebLib functions or HTML Templates.
