(progn (format T "Hey, what's your name?~%") The other is the scratch buffer and should also contain some hints on how to reach a reference guide.Īs a quick test, click inside the Lisp prompt buffer, and type in the following snippet: One of the buffers, the one displaying CL-USER>, is the Lisp prompt. The window should be divided up into two regions, each of which display something called a buffer. Upon launch it might fizzle around for a few seconds and then present you with a window that looks something like this: It has to reside in the portacle directory for it to work. Note that you cannot move or copy sktop elsewhere. The file may also be presented to you as just Portacle. You can then launch it by double-clicking sktop. You can however drag the app into your dock to create a shortcut.ĭownload the latest release and extract it. You must take the whole directory with you. Note that you cannot copy the Portacle.app outside of the portacle directory. You may see several xattr: No such file errors, which can be safely ignored. This will allow you to open the application without security warnings/confirmations. Due to "security" reasons on macOS, you'll then need to run sudo xattr -dr /Applications/portacle (replace /Applications with whatever path you moved your portacle directory to) in order to remove the quarantine attribute from all files in the portacle directory. You can however create a shortcut to the exe to reach it more easily from your desktop.ĭownload the latest release, open the disk image, and move the portacle folder to a dirctory such as /Applications for easy access. Note that portacle.exe is tied to the portacle directory and needs everything within it to function properly. After extraction, you can launch it by double-clicking the portacle.exe. Note that you do not need to append portacle to the end of the path. It will ask you where to install it to, defaulting to your home folder. If you are new to Emacs, Lisp, or both, you should also read the section after this one once you successfully completed the installation.ĭownload the latest release and run it. After that, you can freely move its installation folder around and even take it with you on a memory stick. All you need to do is extract an archive. Portacle is rather straight-forward to setup and use. It allows you to manage changes in code over small and large projects fast and efficiently. Git is perhaps the most widely used version control system today. Quicklisp is the standard Lisp package manager that allows you to retrieve and manage over a thousand libraries with a few keystrokes. SBCL is one of the fastest and most capable Lisp implementations available today. Due to its history and huge community, it is capable of covering pretty much any area of programming and more.īundled with Emacs are some very useful packages, the major ones being Slime, Magit, and Company. The following software packages are included in Portacle:Įmacs is a very flexible and extensible editor that has been around for a long time. It lends itself very well both to absolute beginners of Lisp that just need a good starting point, as well as advanced users that want to minimise the time spent getting everything ready. Since it does not require any complicated installation process, it is set up and running in no time. It is multi-platform and can be run on Windows, OS X, and Linux. Portacle is a complete IDE for Common Lisp that you can take with you on a USB stick. If you’re an Emacs user on macOS, you may want to bookmark Liu’s post in case you run into the problem.For Windows 7+ 圆4 For OS X 10.11+ For Linux 3.13+ 圆4 What This Is I haven’t run into this problem yet and part of the reason for this post is to help me remember what to do in case I do. Then you have to recompile Emacs with defines for FD_SETSIZE and DARWIN_UNLIMITED_SELECT.Īpparently the problem manifests itself when you’re using Emacs with LSP so if you’re an LSP user, you may have go through the-admittedly painful-process. The TL DR is that you have to add a couple of files to your macOS installation and go through a fussy operation to get them installed. Happily Jiacai Liu has a step-by-step procedure for upping the limit. You have to make adjustments to both macOS and Emacs. There is, however, a fix although it’s a bit complicated. Sadly, you can’t fix this by upping the limit with ulimit. This is because Apple has set the default number of open files for a process at 1024. From time to time I see complaints about Emacs having too many open files on macOS.
