A HOL ITP (https://hol-theorem-prover.org/) development environment. Some parts taken from SML-syntax (https://github.com/Takaia/SML-syntax).

• HOL Theorem Prover (https://hol-theorem-prover.org/)
• Sublime Text plugin Terminus (https://github.com/randy3k/Terminus)
• An installed C Compiler

1. You must have HOL installed (https://hol-theorem-prover.org/)
2. You must have Terminus installed (https://github.com/randy3k/Terminus)
3. Clone this repository into your Packages folder and rename it to HOL
4. Inside the newly renamed HOL repo you cloned, build filter.c with your favourite C compiler to an executable called filter in the same folder. For example:

gcc filter.c -o filter

5. In the Sublime Text menu select Preferences -> Package Settings -> HOL -> Settings-User
6. In opened settings file enter:

   {
       "holpath":"/your/path/to/binary/here/hol"
   }
   

1. In the plugin folder (should be called HOL) in the Sublime Text packages folder run git pull
2. Recompile filter.c using you favourite C compiler to an executable called filter. For example:

   gcc filter.c -o filter

• Full colour REPL (Uses HOL's vt100_terminal backend)
• Send selection, lines, and entire files straight to REPL in Sublime
• Automatically format selection/lines into:
  • Goals
  • Subgoals
    • Basic subgoals
    • Sufficient Condition
  • Tactics
  • Quiet mode
• Changes Flags from menus or key bindings
  • Show Types
  • Show Assums
  • Print Goal at Top
  • Print Free Variables
• You cannot directly type in the REPL but instead work from a HOL file

• HOL submenu under Tools in Sublime for all the operations and their keybindings
• Note you must work from a file, you cannot directly type in the REPL
• For more details and more control please see the key bindings and preference files available under the preferences menu
• To change the colour scheme of the REPL use the "Terminus Utilities: Select Theme" command in Sublime Text
• Note: The terminal is speedy enough for interactive use but large imports should be done in quiet mode as they can take some time to colourise!
