v0.5.1

Added

• Flush-left block recovery: a block typed without indentation (e.g. interface X
  followed by spanning-tree bpdufilter at column 0) is now detected by the linter and fixed
  by the formatter — each un-indented child gets a warning and is indented to the file's own
  indent width (falling back to IOS-native 1 space). A line is only treated as a child when
  the command is documented for that block's mode in the loaded command data; unknown or
  global commands end the block and are left alone, so back-to-back blocks without !
  separators are never mis-indented. Covers a broadened opener set: interface, router,
  line, class-map, policy-map, vrf definition, vlan <n>,
  flow record/exporter/monitor, service-template, template, route-map,
  ip/ipv6 access-list, aaa group server, key chain, radius/tacacs server,
  device-tracking policy, crypto map.

• Auto-indent on Enter (experimental, off by default) after any of the block openers
  above, with 1-space indentation contributed as the [cisco] editor default
  (editor.insertSpaces / editor.tabSize). Enable with the
  cisco-ios-lsp.experimental.autoIndent setting; takes effect immediately when toggled.

• Completions: the new block openers are recognised as contexts too (e.g. commands documented
  for VRF or VLAN configuration mode are offered inside vrf definition / vlan blocks); a
  recognised block whose bucket holds no commands falls back to the top-level list.

• Go to definition / find references / rename (F12 / Shift+F12 / F2) for named objects:
  class-maps, policy-maps, named + numbered ACLs, route-maps, prefix-lists, and VRFs, linking
  each definition to the places it is applied (service-policy, access-group,
  access-class, match ..., vrf forwarding, address-family ... vrf, ...).

• Cross-reference diagnostics: referencing an object that is never defined in the file
  warns; defining one that is never referenced shows a hint.

• Folding ranges for every indented config block, spanning ! separators.

• Format on save for the indentation fixes, now driven by VS Code's own
  editor.formatOnSave (contributed as a [cisco] language default).

• Completions now work after a leading no , and accepting a multiword command replaces the
  full typed prefix (no more ip ip address after typing ip addr).

• Unit tests (npm test, node:test) covering the indentation scanner/formatter round-trip,
  block detection, diagnostic positions, data loading, xref index, and document symbols; run
  in CI and on packaging.

• Three new command-reference packs: cat9500-17.18 (1,312 commands, IOS XE 17.18.x),
  cat9500-26.x (1,227 commands, IOS XE 26.x.x), and cat2960x-15.2.6 (435 commands,
  Catalyst 2960-X, classic IOS 15.2(6)E) — extracted from Cisco Command Reference PDFs via
  npm run extract-commands.

Changed

• Faster startup and typing: client and server are bundled with esbuild into single
  dist/ files, the command data ships as one merged JSON parsed lazily right after the LSP
  handshake, per-block completion lists are precomputed once, and the document's split lines
  are cached per version instead of re-split on every keystroke/hover.
• The outline is now served by the language server (textDocument/documentSymbol); symbols
  span their whole block, so breadcrumbs and sticky scroll track the enclosing block.
  Existing cisco-ios-lsp.outline.* settings keep working; same-category blocks now merge
  into one outline group, and class-map labels drop the match-any/match-all prefix.
• Diagnostics precision: every out-of-range VLAN / malformed IPv4 on a line is flagged at its
  own position (previously only the first, sometimes at the wrong column); a corrupt command
  data file is skipped with a logged error instead of crashing the server.
• server.js split into testable server/lib/ modules; ESLint upgraded to v10 flat config.
• _testing/ (real production config backups used as diagnostic ground truth) is no longer
  git-versioned — gitignored and untracked, including its existing history.

Removed

• The cisco-ios-lsp.format.onSave setting — use the standard per-language
  editor.formatOnSave (enabled for cisco files by default) instead.

Fixed

• Banner bodies and certificate payloads are now treated as free text: everything
  between a banner's delimiters (banner login ^C ... ^C, banner motd #...#, including
  one-liners) and the hex dump between certificate ... and quit in a
  crypto pki certificate chain block is skipped by all line scanners — no more
  "Unknown command" / indentation warnings on ASCII-art banner lines, the formatter never
  re-indents that content, it can't create false cross-references, and it no longer
  produces folding ranges.
• Reconciled against a production Catalyst 9500 SD-Access config (_testing/test.cisco):
  • LISP0[.n] and Bluetooth0/4 are recognised interface types.
  • ~140 curated command entries for families the Cat9500 Command Reference PDF doesn't
    cover: call-home, control-plane, netconf-yang, model-driven telemetry
    subscriptions/receivers/transforms, transceiver type, crypto pki
    trustpoints/certificate chains, RADIUS CoA (aaa server radius dynamic-author),
    vrf definition/rd, router lisp (locator-sets, eid-tables, sites, services),
    IS-IS router and interface commands, con/aux line commands, and assorted globals
    (clock, ntp, snmp-server, ip ssh/http/pim/msdp, ...).
  • New block buckets (openers + mode classification + auto-indent + completions):
    call-home, control-plane, crypto pki trustpoint, crypto pki certificate chain, the three telemetry modes, transceiver type, and RADIUS dynamic-author.
  • Cross-reference fixes: a LISP prefix-list NAME block opener counts as the
    prefix-list's definition, and in ntp access-group peer ACL the keyword peer is no
    longer mistaken for the ACL name (the ACL itself is now the reference).
• scripts/extract-commands.js: the TOC running-header noise filter only matched the IOS-XE
  Command Reference, Cisco IOS XE wording. Classic-IOS "Consolidated Platform Command
  Reference" manuals (e.g. the new 2960-X pack) repeat Command Reference, Cisco IOS Release instead, so those header lines leaked through and corrupted 13 TOC entries by
  gluing onto the next command name. Broadened NOISE_RE to match the shared prefix.

Full Changelog: v0.5.0...v0.5.1

v0.5.0

Added

• Bundled TextMate grammar (syntaxes/cisco.tmLanguage.json) and language-configuration.json
  for the cisco language, adapted from Y-Ysss.cisco-config-highlight (MIT licensed; see
  THIRD_PARTY_NOTICES.md). The extension now provides its own syntax highlighting, including
  data-driven command-root highlighting (keyword.control.command.cisco) derived from the
  same generated command list described below.
• Outline panel / breadcrumbs support (client/registerOutlineSymbol.js,
  client/symbolsInfo.js), also adapted from Y-Ysss.cisco-config-highlight. Off by default;
  enable with cisco-ios-lsp.outline.showSymbolsInOutlinePanel, configure categories with
  cisco-ios-lsp.outline.symbolsList.
• README sections on coexisting with Y-Ysss.cisco-config-highlight and on Material Icon
  Theme file-icon associations.
• Command data is now generated from official Cisco Command Reference PDFs instead of
  hand-typed: completions, hover docs, and diagnostics cover 1,315 commands across 16
  chapters of the Catalyst 9500 IOS XE 17.15.x reference (up from ~150 hand-picked entries),
  via a new re-runnable extractor (npm run extract-commands) so future manuals (other
  platforms/releases) can be added the same way.
• New exec completion bucket for show/clear/debug-style EXEC-mode commands (~40% of
  the loaded command set), alongside the existing interface/router/class-map/policy-map/line
  contextual buckets.
• Hover now does a longest-prefix match against the full command set and shows every
  documented variant when a name is ambiguous (e.g. a command meaning different things in
  different modes), instead of a small fixed lookup table.
• COMMAND_COVERAGE.md and cspell.json are now regenerated from the same command data.

Changed

• Completions now resolve their documentation lazily (resolveProvider) instead of
  eagerly, since completion lists can now be much larger.

Removed

• extensionDependencies on Y-Ysss.cisco-config-highlight — no longer required since
  highlighting is bundled. That extension can still be installed alongside this one.

Full Changelog: v0.2.0...v0.5.0

v0.2.0

Added

• Startup update check: notifies when a newer version is published on GitHub Releases, with
  an "Open Releases" action. Inactive while the repo is private; activates automatically once
  it is public. Toggle with the cisco-ios-lsp.checkForUpdates setting.

Full Changelog: v0.1.0...v0.2.0

v0.1.0

Initial release.

Added

• Language server for Cisco IOS/IOS-XE config files (built on the cisco language ID
  from Y-Ysss.cisco-config-highlight):
  • Completions — context-aware by config block (interface, router, class-map,
    policy-map, line, global).
  • Hover — syntax reminders for known keywords.
  • Diagnostics — unknown top-level commands, invalid interface types, out-of-range
    VLAN IDs, malformed IPv4 addresses.
• Packaging as a shareable .vsix (npm run package), with production dependencies
  bundled (no build step).
• Original Golden Gate Bridge icon with a terminal-style wordmark.
• Automated releases: pushing a vX.Y.Z tag builds and publishes the .vsix via GitHub
  Actions.
