Know of an Ocaml Ide

Know of an OCaml IDE?

Emacs in Caml mode, or Tuareg mode, or TypeRex mode. TypeRex adds auto-completion to Taureg in emacs - a really nice feature for people who prefer the more graphical IDE's.

Looking for OCaml IDE

There is TypeRex, a new development environment for OCaml. Here is a summary of TypeRex features:

  • Improved syntax coloring
  • Auto-completion of identifiers (experimental)
  • Browsing of identifiers: show type and comment, go to definition, cycle between alternate definitions, and semantic grep;
  • Strictly semantic-preserving, local and whole-program refactoring:

    • renaming identifiers and compilation units
    • open elimination and reference simplification
  • Robust w.r.t. not-recompiled, possibly unsaved buffers
  • Scalable (used regularly on a few hundreds of source files)

There are some screenshots available on the website. The first release candidate is out since yesterday.

EDIT: The first release (v1.0) is out now :-)

IDE for OCaml language

Editors

• Emacs

◦ ocaml-mode from the standard distribution

◦ alternative tuareg-mode https://forge.ocamlcore.org/projects/tuareg/

− cheat-sheet: http://www.ocamlpro.com/files/tuareg-mode.pdf

◦ camldebug intergration with debugger

◦ type feedback with C-c C-t key shortcut, needs .annot files

• Vim

◦ OMLet plugin
http://www.lix.polytechnique.fr/~dbaelde/productions/omlet.html

◦ For type lookup: either https://github.com/avsm/ocaml-annot

− or http://www.vim.org/scripts/script.php?script_id=2025

− also? http://www.vim.org/scripts/script.php?script_id=1197

• Eclipse

◦ OCaml Development Tools http://ocamldt.free.fr/

◦ an old plugin OcaIDE http://www.algo-prog.info/ocaide/

• TypeRex http://www.typerex.org/

◦ currently mostly as typerex-mode for Emacs but integration with
other editors will become better

◦ Auto-completion of identifiers (experimental)

◦ Browsing of identifiers: show type and comment, go to definition

◦ local and whole-program refactoring: renaming identifiers and compilation units, open elimination

• Some dedicated editors

◦ OCamlEditor http://ocamleditor.forge.ocamlcore.org/

◦ ocamlbrowser inspects libraries and programs

− browsing contents of modules

− search by name and by type

− basic editing, with syntax highlighting

◦ Cameleon http://home.gna.org/cameleon/ (older)

◦ Camelia http://camelia.sourceforge.net/ (even older)

NEW: editor OCaml-top, with syntax highlighting, indentation, type display, work well on all systems.

NEW: Merlin, similar to TypeRex but works better with work-in-progress files, has front-ends to Vim and Emacs currently.

how to search for OCaml functions by name and type

awesome-ocaml has a section on dev tools that should be helpful.

  • ocamloscope (github) is sort of an Hoogle for OCaml. Search by name works well. Search by type is less good.
  • For local search by name, ocp-browser provides a convenient TUI.
  • In your editor, merlin and ocp-index can do lookup-to-definition and lookup-documentation.
  • There is a WIP public instance of odig here with a lot (but not all) packages. You can use odig locally too, as stated in another answer.

P.S. The function you are looking for is @@, and it's in the standard library.

What do I need to know to create a source code editor?

You need to know:

  • OCAML Syntax, Features, Keywords, Functions etc...
  • C# as this is your native language I guess
  • You need to know what features you wanna implement
  • ...if it's using a GUI or just from a terminal like nano/vim
  • how syntax highlighting works
  • how to open and save files
  • how autocompletion works
  • etc..

You might want to take look at some open source editors like dev-c++ or gedit

Also, as you in person are more web-devvy, you might want to start creating one which runs in a web browser. This is often easier and helps you understand the basics of creating a code editor. Later you can always write one for desktops.

Is there a single working OCaml IDE?

I would like to thank everybody for their help. I finally found some installation instructions for the tuareg mode in EMACS. In case anybody else is having the same problem that I was there are VERY clear instructions here

How to install tuareg

Hopefully I can now translate some stuff into OCaml that I have been working on in other languages and post some of my projects. Thanks again for all of the help.

Converting OCaml to F#: Is there an OCaml IDE with GUI debugging like Visual Studio

I was unable to find an OCaml GUI debugger with the same ability as Visual Studio using F# that meet my requirements.

If someone does find one or creates one and post that as an answer I will gladly give them them accept vote.

Call graph generator for OCaml or Reason

I actually never used it but only thing I can remember for OCaml is pfff. Readme says that it supports codemaps and codegraphs.
