Installation

@Juhana’s Borogove lets you edit and run I7 (10.1, 9.3/6M62, or 8.5/6G60) online: experiment without installing anything. Borogove snippets allows sharing code examples.

Official packages mentioned below available at I7 Downloads.

MacOS

Use the package on the I7 site; not the App Store’s.
Known issues:

An unofficial MacOS IDE release addresses these. Testing examples in Extension Projects doesn’t work.

Windows

Use the package on the I7 site (said to work with any version of Windows from XP SP 3 on). Or there’s a current beta release of a new Windows version that allows compiling for 6L02 and 6L38 as well as 6M62. It’s 64-bit-only, and has been tested only on Windows 10, but may work with older versions. Be warned that there have been multiple reports of security/antivirus programs causing problems with it: Avast, AVG, Windows Defender.

Linux

The 6M62 IDE package have uses GTK2; for a long time, GTK3 has been the norm, making the IDE hard to build on a modern Linux.

Unofficial rpm/deb IDE packages

The official download page also offers a CLI-only version for Linux, which comes with “the cheesy Perl interface”. Or consult How to use ni, inform6, and cBlorb by CLI for info on using those commands directly. Some projects to help are Vimform7, the Inform 7 extension for VS code, Spaceformacs, and inf7.

Linux kernels >= 4.11 (c. 2017) are incompatible with ni prior to 6M62.
For 6L38 or older use an old Linux in a VM or Windows Inform in WINE (or use 6G60 online at playfic.com or borogove.app).

The official packages include components that have more recent versions. Some updates:

Versions

Most 6L02 or 6L38 information is relevant for 6M62. 6L02 had many backwards-incompatible changes: code written for 6G60 or earlier is unlikely to compile in 6L02 or later. This post usually notes the version as of which something was current.

Manuals/Books

References

The actual syntax the I7 compiler uses to parse I7 code is in Languages/English/Syntax.preform in your installation’s Internal directory. The Backus-Naur Form syntax provided isn’t accurate. See the Syntax.preform documentation PDF (6L02). Syntax.preform also lets you see what irregular verbs and plurals Inform 7 handles and how.

Extensions

Counterfeit Monkey’s Extensions: beyond the many unique extensions, many other extensions included here are modified from their original versions.

Separate from the Authoring > Inform 7 category here, there is a Technical Development > Inform Extensions category chiefly discussing issues with existing published extensions

Standard Rules

I7 includes the Standard Rules with every game. They’re well-commented and the authority on the world model and defaults (used to be in Appendix A of the documentation). They can be browsed in the IDE. (See “Contents” within any compiled game.)

Warning (Writing in Inform 27.14): things in the SR that look modifiable may not really be; they could be interdependent with something hard-coded in the compiler. And beware that all of the past three versions’ SRs (6L02, 6L38, 6M62) are marked Version 3/120430, but each is different. (Likewise, 6E59 through 6G60’s Standard Rules are all marked Version 2/090402 but each is different.)
