Creating compiled search TRIE file for argument string completion

Posted on 4/20/2016

I'd like to generate a compiled search TRIE file (like those found in $InstallationDirectory\SystemFiles\FrontEnd\SystemResources\FunctionalFrequency\) to help implement the auto-completion feature on user-defined functions.

As described in File-name completion for custom functions, I could directly add a list of strings into the specialArgFunctions.tr file. However, my lists of arguments is long and likely to change during development, so I'd prefer to point to a TRIE file that I can update as needed.

How can I create a compiled TRIE file? Can this be done in Mathematica or Workbench? Is the TRIE file extension structure documented anywhere?

These files are here in v11:

FileNames["*.trie", 
  PacletFind["AutoCompletionData"][[1]]["Location"],
  Infinity
 ]

Similarly in 11 is CACADumpTriePacket` which seems to extract the properties from a trie file, but not the trie format itself.

To create a compiled TRIE file for argument string completion in Mathematica, especially for dynamic user-defined functions, here's a structured approach based on available insights and practical workarounds:

Key Observations:

  1. TRIE File Purpose: TRIE files (e.g., in $InstallationDirectory\SystemFiles\FrontEnd\SystemResources\FunctionalFrequency) are used by Mathematica's front end fo...

Short answer: you can’t (at least not in any supported way).

  • The .trie files used by the front end for autocompletion are an internal, undocumented format. There is no public tool or documented API in the Wolfram Language or Workbench to compile them from your own data.
  • The only front‑end packet people have found that interacts with these files is CA`CADumpTriePacket, which lets you inspect/d...

Mathematica’s “​.trie” files (the ones you find under

$InstallationDirectory/SystemFiles/FrontEnd/SystemResources/FunctionalFrequency

) are an internal, binary format produced by Wolfram’s own build‐system for the front end. There is no public “Export[... , “.trie”]” nor any documented specification of that format, and no supported Mathematica or Workbench function to generate t...

<think> We are going to address the question of creating a compiled TRIE file for argument string completion in Mathematica. The user wants to generate a .trie file that can be used for autocompletion of user-defined function arguments, similar to the ones found in the system directories.

Background

  • The system uses .trie files for efficient autocompletion. These are binary files that store ...

Excellent question. This delves into some of the more advanced, undocumented FrontEnd customization capabilities. The good news is that yes, this is possible to do programmatically from within Mathematica.

The key lies in a set of undocumented functions within the FrontEndCA`` context (CA likely stands for Code Assist).

Here's a complete workflow for creating a custom TRIE file and integrati...

Short answer
The file format that the FrontEnd reads out of “ *.trie ” files is not documented and is not written by any public-facing Wolfram-Language function.
Only the internal “Code Assist” paclet that ships with the product knows how to turn a list of strings (or of rules) into the compact binary form that the FrontEnd loads. Consequently a compiled trie can only be produced with the sam...

This is an interesting question about creating custom TRIE files for Mathematica's auto-completion system. Unfortunately, creating compiled TRIE files (.tr or .trie) directly is not straightforward because:

The Challenge

  1. Undocumented Format: The TRIE file format used by Mathematica is proprietary and undocumented. These are binary files with a specific internal structure that Wolfram h...

Creating Compiled TRIE Files for Argument String Completion in Mathematica

To create a compiled TRIE file for auto-completion of user-defined functions in Mathematica, you'll need to work with Mathematica's internal auto-completion system. Here's how you can approach this:

Short answer
The “*.trie” files that the front end uses for its various auto‐completion tasks are produced by private C/C++ code that belongs to the build system of the Mathematica / Wolfram Language front end.
The file format is not documented, there is no public Wolfram-Language function (in the kernel or in Workbench) that can write such a file, and the only interface that is exposed to the...
