OpenSIPS Routing Script

Language support for the OpenSIPS routing script (opensips.cfg) — the real OpenSIPS parser checks your config as you work, and completion, hover documentation, and navigation come from the actual documentation of your OpenSIPS version. Platform builds bundle the language server: install the extension and it just works.

Features

• Diagnostics you can trust — every save runs opensips -C, so the squiggles are the real parser's verdict, at the exact line and column, for exactly your OpenSIPS version: Parameter <fr_timeot> not found in module <tm> - can't set.
• Completion that knows context
  • loadmodule " → every module in your source tree
  • modparam("tm", " → tm's parameters, with their documentation
  • inside a route → exported functions of the modules you loaded, plus core functions, parameters, route names, and keywords
  • $ → pseudo-variables ($ru, $si, …) with descriptions
  • functions insert as snippets — the cursor lands between the parentheses
• Hover documentation for functions, parameters, modules, and pseudo-variables, harvested from OpenSIPS's own docs.
• Navigation — Ctrl+Click route(name) to jump to its definition (even into an include_file); Ctrl+Shift+O lists every route block with its full extent; route blocks fold.
• Signature help — type ( or , in a call and the signature pops up with the active parameter highlighted.
• References & rename — Shift+F12 lists every call site of a route; F2 renames it everywhere, quoted call sites included.
• Instant warnings — undefined route() targets, duplicate route definitions, and modparams your OpenSIPS version doesn't document are flagged as you type, no save needed.
• Quick fixes — the lightbulb loads the module that exports an unknown function, or creates a missing route stub.
• Workspace symbols & code lenses — Ctrl+T finds any route; reference counts appear above route definitions.
• Semantic highlighting — route names and pseudo-variables are colored by real analysis, even inside strings.
• Snippets — route, failure_route, ifmethod, modparam, switch, xlog, and more.
• Safe by default — in untrusted workspaces diagnostics stay off (checking a config loads its modules); everything else keeps working.

Quick start

1. Install this extension (the platform packages bundle the server — Linux, macOS, and Windows, x64 and arm64).
2. Open a folder containing an opensips.cfg — syntax colors, completion, and navigation work immediately.
3. For live error checking, point Settings → Opensips Lsp: Opensips Path at your opensips binary and save the file.
4. For the richest completion docs, set Opensips Src to an OpenSIPS source tree matching your version.

Requirements

None to start — the server is bundled. Optional, for the full experience: an opensips binary (diagnostics) and an OpenSIPS source tree (documentation). Supports OpenSIPS 4.x and 3.6.x.
