tdl-extension

This is an experimental VSCode extension of Type Definition Language (TDL) files used in DELPH-IN for computational linguistic processing with HPSG and MRS analysis. The syntax of TDL files can be viewed here. It is still under development -- usable, but expect a lot of bugs, and the speed is not satisfactory for large grammars such as ERG (mainly due to the large lexicon.tdl), but should be sufficient for grammars generated from the Grammar Matrix.

The extension currently supports (assuming type and feature names are of ascii characters only):

• Syntactic Highlights: comments, strings, type docstrings, brackets, definition operator (DEFOP, :=), multiple inheritance operator (AND, &), tag variables;
• Semantic Highlights of defined types (except for *top*);
• Go-to definitions of defined types with docstring display on hovering;
• Autocompletion of types and features based on attribute paths (buggy);
• Automatic indentation upon newline (buggy).

Setup

Locally

• Install nvm and install/update node.js (if needed). This website serves as a good tutorial. Alternatively, the docker file (see below) should contain similar information.
• Install node modules and compile typescript files:

$ cd /path/to/tdl/extension/directory
$ npm install
$ npm run compile

• Press F5 (maybe you need to select extension.ts in the primary side bar before doing so) to start the Extension Development Host in VSCode.
• Select the local grammar folder and start programming.

Inside Docker Container

• The docker file in the repo should provide a good start. Make sure to modify the following code to specify your own local directory of the extension:

# NOTE: type your own directory here
# WORKDIR /path/to/your/extension/directory

• Build the docker image and container. Note that we need to specifiy the grammar folder (or any folder that contains it) as the workspace:

$ cd /path/to/tdl/extension/directory
$ docker build -t your-image-name .
$ docker run -it --name your-container-name -v /your/grammar/folder:/home/dockeruser/workspace your-image-name

• Inside VSCode, press F1 and select Dev Containers: Attach to Running Container ...
• Select "Open Folder..." and select or type the folder you typed as WORKDIR above.
• Press F5 (maybe you need to select extension.ts in the primary side bar before doing so) to start the Extension Development Host in VSCode. to start the Extension Development Host.
• Select /home/dockeruser/workspace as the workspace inside the development host.
• You can start programming now.
