https://srfi.schemers.org/srfi-197/srfi-197.html Add the key files from the upstream implementation. These files are the unmodified versions from the upstream repository https://github.com/scheme-requests-for-implementation/srfi-197.git as of this commit (final-5-g43eae09): commit 43eae0941e4c69b11b5609464b7d8827785c3897 Author: Arthur A. Gleckler <srfi@speechcode.com> Date: Sun Apr 20 20:30:25 2025 -0700 Regenerate landing page and README. except that the upstream LICENSE/MIT.txt referred to by the SPDX headers has been added to the top of srfi-197.scm and srfi-197.text, and srfi-197.scm has been reindented. srfi-197.html already includes its own copyright statement. srfi-197.scm is upstream srfi-197-syntax-case.scm, and was chosen instead of upstream srfi-197.scm because Guile doesn't currently handle syntax-rules with custom elipsis. For now add the html documentation as-is; convert it to texinfo later. * doc/ref/srfi-197.html: Add new file. * module/srfi/srfi-197.scm: Add new file (upstream srfi-197-syntax-case.scm). * test-suite/tests/srfi-197.test: Add new file (upstream test.scm). |

This directory contains some tests for Guile, and some generic test support code. To run these tests, you will need a version of Guile more recent than 15 Feb 1999 --- the tests use the (ice-9 and-let*) and (ice-9 getopt-long) modules, which were added to Guile around then. For information about how to run the test suite, read the usage instructions in the comments at the top of the guile-test script. You can reference the file `lib.scm' from your own code as the module (test-suite lib); it also has comments at the top and before each function explaining what's going on. Please write more Guile tests, and send them to bug-guile@gnu.org. We'll merge them into the distribution. All test suites must be licensed for our use under the GPL, but I don't think I'm going to collect assignment papers for them. Some test suite philosophy: GDB has an extensive test suite --- around 6300 tests. Every time the test suite catches a bug, it's great. GDB is so complicated that folks are often unable to get a solid understanding of the code before making a change --- we just don't have time. You'll see people say things like, "Here's a fix for X; it doesn't cause any regressions." The subtext is, I made a change that looks reasonable, and the test suite didn't complain, so it must be okay. I think this is terrible, because it suggests that the writer is using the test suite as a substitute for having a rock-solid explanation of why their changes are correct. The problem is that any test suite is woefully incomplete. Diligent reasoning about code can catch corner conditions or limitations that no test suite will ever find. Jim's rule for test suites: Every test suite failure should be a complete, mysterious surprise, never a possibility you were prepared for. Any other attitude indicates that you're using the test suite as a crutch, which you need only because your understanding is weak.
