Setting up an OCaml environment for Programming Posted in and tagged on May 1, 2015 • • • • • • • • • • Introduction Note: OCaml is installed on the Linuxlab cluster. Finding the right mix of tools to edit, compile, and debug programming projects can be a frustrating challenge. I’m going to discuss the setup I use and recommend for developing with OCaml. Within the past few years, OCaml has become an especially appealing language for functional programming because of its growing tooling support. Its predecessor,, was a well designed and useful research language, but developing large projects in it was troublesome because there wasn’t a set of standard tools and libraries within the community (e.g., provided its own build system, and were two separate optimizing compilers).
Additionally, the user community was relatively small and it lacked the support of libraries and packages that have become essential components of other communities. However, with a larger open source community and more commercial backing (e.g., ), OCaml has acquired a mature set of tools to ease development. The foundations of my toolchain are: • The package manager, for managing different versions of OCaml and associated sets of packages. • ( ocamlbuild) for compiling OCaml projects and greatly simplifying Makefiles. • taureg-mode as a mode for emacs, and for vim. • Merlin, which turns emacs and vim into tools closer to IDEs for OCaml.
Quick start Clone and follow along. OPAM OPAM is a package manager for OCaml, similar to. It allows us to maintain multiple versions of OCaml compilers, along with packages that work with them.
It includes a large set of libraries and makes them easy to install. Installation instructions for OPAM can be found. OPAM supports many package management systems, so you should be able to install it via apt-get, brew, or whichever you use. If you’re using a Mac, I recommand using the management system.
Word for mac do not snap to grid. Does anyone know how to turn off snap to grid in Microsoft Word for Mac 2004? I am trying to move text boxes and they just keep jumping around and will not line up the way I want them to because of some stupid snap to grid type thing. It sounds like it would be something people would really like to do doesn't it, moving a text box just a little bit. Snap objects to a grid in Word for Mac - Activate the snap-to options On the Word menu, click Preferences. In Word Preferences, under Authoring and Proofing Tools, click Edit. In Edit, click Grid Options. In Grid Options, select the type of snap-to behavior that you want. Change the spacing. Snap an object to the Grid or to a Shape. Word; 2003 / 2007 / 2010 / 2013. Snap objects to grid when the gridlines are not displayed - Select this check box if you want Word to snap objects to the grid even when you can't see the gridlines. If you want to make these grid settings the default for the current template. To snap shapes or other objects to the closest intersection of the grid when the grid is not visible, under Show grid, check Snap objects to grid when the gridlines are not displayed. To snap shapes or other objects to grid lines of other shapes or objects, under Object Snapping, check Snap objects to other objects.
There are also options for MacPorts as well. If you’re not using either of these systems, I’d recommend installing Homebrew first, but there are other options listed on OPAM’s install page (including installing from source). I agree that it’s a pain to install a package manager to install another package manager, but it gets better once its installed! Once you’re up and running you should be able to use the command opam init, which will initialize your opam installation.
Gives some basic uses for OPAM, but the big ones are: • opam switch for switching between versions. I usually switch into the main version I use and do all of my development with that. The only real reason to switch between versions is if you depend on a feature that exists in a certain version of OCaml. You will rarely run into this unless you use very cutting edge features of the type system. The output of opam switch will list a set of compilers available for you: system I system System compiler (4.00.1) 4.03.0+trunk I 4.03.0+trunk latest trunk snapshot 4.02.1 C 4.02.1 Official 4.02.1 release 4.01.0 I 4.01.0 Official 4.01.0 release -- -- 3.11.2 Official 3.11.2 release -- -- 3.12.1 Official 3.12.1 release -- -- 4.00.0 Official 4.00.0 release -- -- 4.00.1 Official 4.00.1 release -- -- 4.02.0 Official 4.02.0 release With your current one listed.
You can switch to another compiler (and the set of packages you’ve installed for it) by specifying the version after the switch. Note that you’ll have to run eval `opam config env` After switching. This updates your environment variables so that commands such as ocamlc or ocamlopt (the compiler) point at the versions you intend to use. • opam list lists the set of packages you have installed. • opam install allows you to install a package. As an example, if I wanted to use Jane Street’s library (which provides a large set of utilities extending the standard library and useful for day to day programming) I would do Kristophers-MacBook-Pro-2:~ micinski$ opam install core The following actions will be performed: - install comparelib.109.60.00 [required by core].
