BBEdit

Umple for BBEdit

Umple language support for BBEdit 14+, providing syntax highlighting, diagnostics, code completion, go-to-definition, find references, rename, formatting, and document symbols for .ump files.

BBEdit has built-in Language Server Protocol support — no plugins required.

How It Works

Two systems work together:

BBEdit explicitly does NOT use LSP for syntax highlighting — you need both the plist and the server.

Prerequisites

• BBEdit 14+ (built-in LSP support)
• Node.js 18+ (for running the LSP server)
• Java 11+ (optional — only needed for diagnostics from the Umple compiler)

Installation

1. Install the LSP server

npm install -g umple-lsp-server

Download umplesync.jar (needed for diagnostics):

curl -fSL -o "$(npm root -g)/umple-lsp-server/umplesync.jar" \
  https://try.umple.org/scripts/umplesync.jar

2. Install the Codeless Language Module

The Umple.plist file in this directory is a complete Codeless Language Module that provides both syntax coloring and LSP server auto-discovery. Copy it to BBEdit’s Language Modules folder:

mkdir -p ~/Library/Application\ Support/BBEdit/Language\ Modules
cp Umple.plist ~/Library/Application\ Support/BBEdit/Language\ Modules/

Or if you cloned this repo:

mkdir -p ~/Library/Application\ Support/BBEdit/Language\ Modules
cp editors/bbedit/Umple.plist ~/Library/Application\ Support/BBEdit/Language\ Modules/

You may bneed to set the initialization options as specified n Section 5.

3. Restart BBEdit

Quit BBEdit completely and relaunch. Language modules are only loaded at startup.

4. Verify

1. Open any .ump file
2. Check the language selector at the bottom of the editor — it should show Umple
3. Check BBEdit > Settings > Languages > Umple > Server — the status dot should be green (server found)
4. If the dot is red, see Troubleshooting below
5. Create an Umple file (.ump suffix) and type statemachine sm {} and save the file. Verify that the keyword statemachine is coloured. If not see Troubleshooting
6. In the same Umple file, type an error (such as a single line with junk) and save the file. Verify that a pink colour appears on the line number and also in a little triangle at the top; click either of these to see the diagnostic information; then click Show All to see the diagnostics panel. If this does not work follow the directions in the next section to set initialization options.

5. Set initialization options (optional but likely needed)

If diagnostics don’t work, the server may need help finding umplesync.jar.

Find the jar path:

echo "$(npm root -g)/umple-lsp-server/umplesync.jar"

Create a configuration directory:

mkdir -p ~/Library/Application\ Support/BBEdit/Language\ Servers/Configuration

Save the following om Umple.json configuration file in the Configuration directory you just created (i.e. as ~/Library/Application Support/BBEdit/Language Servers/Configuration/Umple.json): (If you have saved umplesync.jar somewhere different from /usr/local/lib/node_modules/umple-lsp-server/ then change the path in the following):

{
  // Path to umplesync.jar for diagnostics
  "initializationOptions": {
    "umpleSyncJarPath": "/usr/local/lib/node_modules/umple-lsp-server/umplesync.jar"
  }
}

Tell BBEdit to use the above configuration file by going to Settings / Languages/ Custom Settings / double-click Umple, then select Server, then in the Configuration field select Umple

BBEdit supports C-style comments (//, /* */) in these JSON config files.

Features

From the Codeless Language Module (plist)

• Syntax highlighting — Keywords, comments (//, /* */), and strings ("...") are colored
• Comment/uncomment — Cmd+/ toggles line comments; Cmd+Shift+/ toggles block comments
• Block folding — { / } blocks can be folded

From the LSP Server

Not supported by BBEdit

• Hover — BBEdit does not support textDocument/hover
• Semantic tokens — Syntax coloring comes from the plist, not the LSP

How the Plist Works

The Umple.plist file does two things:

1. Language definition — Maps .ump files to the “Umple” language, defines comment/string delimiters, and provides a keyword list for syntax coloring.

2. LSP auto-discovery — The BBLMLanguageServerInfo dictionary tells BBEdit to automatically launch umple-lsp-server --stdio when .ump files are opened:

<key>BBLMLanguageServerInfo</key>
<dict>
    <key>ServerCommand</key>
    <string>umple-lsp-server</string>
    <key>ServerArguments</key>
    <array>
        <string>--stdio</string>
    </array>
    <key>ServerLanguageID</key>
    <string>umple</string>
</dict>

This means no manual configuration in Settings > Languages > Server is needed — it’s all automatic from the plist.

Troubleshooting

Server status dot is red

The red dot in Settings > Languages > Umple > Server means BBEdit found the configuration but can’t locate the executable.

Common cause: BBEdit reads $PATH from ~/.zshenv, NOT ~/.zshrc. If you installed Node.js via nvm, fnm, or Homebrew and only added it to PATH in .zshrc, BBEdit won’t find it.

Fix options:

1. Add the PATH export to ~/.zshenv:

   # ~/.zshenv
   export PATH="/opt/homebrew/bin:$PATH"
   # or for nvm:
   export NVM_DIR="$HOME/.nvm"
   [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"

2. Or use the full absolute path: open Settings > Languages > Umple > Server and set Command to the full path:

   which umple-lsp-server
   # e.g., /opt/homebrew/bin/umple-lsp-server

3. Or symlink into BBEdit’s Language Servers directory:

   mkdir -p ~/Library/Application\ Support/BBEdit/Language\ Servers
   ln -s "$(which umple-lsp-server)" ~/Library/Application\ Support/BBEdit/Language\ Servers/

Server status dot is gray

Gray means the server is not configured. Make sure Umple.plist is in ~/Library/Application Support/BBEdit/Language Modules/ and you’ve restarted BBEdit.

No diagnostics

1. Ensure umplesync.jar exists:

   ls "$(npm root -g)/umple-lsp-server/umplesync.jar"

2. Verify Java is installed: java -version

3. If the jar is in a non-standard location, create Umple.json (see step 5 above)

LSP features not working

Check the debug log:

~/Library/Logs/BBEdit/LanguageServerProtocol-Umple.txt

This log shows all JSON-RPC messages between BBEdit and the server.

Server hangs on quit

If BBEdit hangs when closing, the server may not be responding to the exit notification. Fix:

defaults write com.barebones.bbedit ForceQuitLSPServerAfterExit_umple-lsp-server -int 2

This tells BBEdit to force-kill the server after 2 seconds if it doesn’t exit cleanly.

Per-Project Configuration

For project-specific settings, place a .BBEditLSPWorkspaceConfig.json file in the project root:

{
  // Project-specific LSP settings
}

BBEdit passes this to the server as workspace configuration.

Updating

npm update -g umple-lsp-server

Then restart BBEdit. The plist does not need updating unless new keywords are added to the Umple language.

Customizing Keywords

The keyword list in Umple.plist controls which identifiers get syntax coloring. To add or remove keywords, edit the BBLMKeywordList array in the plist and restart BBEdit. The full list of keywords is organized by category:

• Entity declarations: class, interface, trait, enum, association, associationClass, namespace, statemachine
• Class body: isA, singleton, immutable, abstract, lazy, const, autounique, defaulted, depend, use, key
• Visibility: public, private, protected, internal
• Types: Integer, String, Boolean, Double, Float, Date, Time, void
• State machine: queued, pooled, entry, exit, do, final, unspecified, as, afterEvery
• Code injection: before, after, around
• Directives: generate, mixset, require, trace, tracecase
