jsp-taglib-intellisense is a VS Code extension for JSP projects that reads taglib declarations and provides prefix-aware tag completion and hover documentation.

It currently ships built-in metadata for JSTL core tags and Spring form tags, including localized hover content in English and Korean.

Features

Normalizes jakarta.tags.core and legacy JSTL core URIs into the same built-in tag set.
Supports all built-in JSTL core tags: catch, choose, if, import, forEach, forTokens, out, otherwise, param, redirect, remove, set, url, when
Supports all built-in Spring form tags: button, checkbox, checkboxes, errors, form, hidden, input, label, option, options, password, radiobutton, radiobuttons, select, textarea
Completes taglib directives in both classic JSP syntax (<%@ taglib ... %>) and XML syntax (<jsp:directive.taglib ... />).
Completes uri and prefix values while authoring taglib directives.
Follows static includes such as <%@ include file="..." %> and <jsp:directive.include ... /> to collect declared taglibs across related files.
Restricts completions to real tag-opening contexts such as <c: to avoid noisy suggestions in plain text.
Registers .jsp, .jspf, .jspx, .tag, and .tagx as JSP-related files for activation.
Shows hover documentation on supported tag names with: Y / N required flags, default values, attribute descriptions, and per-tag notes when available
Adapts hover documentation to the VS Code UI language: Korean UI shows Korean content, English UI shows English content
