92 | .SH DESCRIPTION | |
93 | . | |
94 | The | |
95 | .B runlisp | |
96 | program has two main functions. | |
97 | .hP 1. | |
98 | It can be used in a script's | |
99 | .RB ` #! ' | |
100 | line to run a Common Lisp script. | |
101 | .hP 2. | |
102 | It can be used in build scripts | |
103 | to invoke a Common Lisp system, | |
104 | e.g., to build a standalone program. | |
105 | . | |
e29834b8 MW |
106 | .SS "Options" |
107 | Options are read from the command line, as usual, | |
10427eb2 MW |
108 | but also (by default) from the script's second line, |
109 | following a | |
e29834b8 | 110 | .RB ` @RUNLISP: ' |
10427eb2 | 111 | marker: see |
e29834b8 | 112 | .B Operation |

122 | command-line syntax |
123 | and a description of the command-line options | |
124 | to standard output | |
125 | and immediately exit with status 0. | |

e29834b8 MW |
137 | Don't check for a custom Lisp image. |
138 | Usually, | |
139 | .B runlisp | |
140 | tries to start Lisp systems using a custom image, | |
141 | so that they'll start more quickly; | |
142 | the | |
143 | .RB ` \-D ' | |
144 | option forces the use of the default `vanilla' image | |
145 | provided with the system. | |
146 | There's not usually any good reason to prefer the vanilla image, | |
147 | except for performance comparisons, or debugging | |
148 | .B runlisp | |
149 | itself. | |

e29834b8 MW |
170 | Use one of the named Lisp systems. |
171 | Each | |
172 | .I sys | |
10427eb2 MW |
173 | must name a supported Lisp system; |
174 | the names are separated by a comma | |
175 | .RB ` , ' | |
176 | and/or one or more whitespace characters. | |
e29834b8 MW |
177 | This option may be given more than once: |
178 | the effect is the same as a single option | |
179 | listing all of the systems named, in the same order. | |
180 | If a system is named more than once, | |
181 | a warning is issued (at verbosity level 1 or higher), | |
182 | and all but the first occurrence is ignored. | |
183 | . | |
184 | .TP | |
10427eb2 MW |

186 | Read configuration from | |
187 | .IR conf . | |
188 | If | |
189 | .I conf | |
190 | is a directory, then all of the files within | |
191 | whose names end with | |
192 | .RB ` .conf ', | |
193 | are loaded, in ascending lexicographical order; | |
194 | otherwise, | |
195 | .I conf | |
196 | is opened as a file. | |
af677646 | 197 | All of the files are expected to be as described in |

223 | Don't actually start the Lisp environment. |
224 | This may be helpful for the curious, | |
225 | in conjunction with | |
226 | .RB ` \-v ' | |
227 | to increase the verbosity. | |
10427eb2 MW |

253 | to standard output | |
254 | (as if by | |
255 | .BR prin1 ). | |
256 | If a form produces multiple values, | |
257 | they are printed on a single line, | |
258 | separated by a single space character; | |
259 | if a form produces no values at all, | |
260 | then nothing is printed \(en not even a newline character. | |
261 | This option causes | |
262 | .B runlisp | |
263 | to execute in | |
264 | .I eval | |

295 | .RB ` \-p ' | |
296 | options may only be given on the command-line itself, | |
297 | not following a | |
298 | .RB `@ RUNLISP: ' | |
10427eb2 | 299 | marker in a script. |
e29834b8 MW |
300 | These options may be given multiple times: |
301 | they will be processed in the order given. | |
302 | If any of these options is given, then no | |
303 | .I script | |
304 | name will be parsed; | |
305 | instead, use | |
306 | .RB ` \-l ' | |
307 | to load code from files. | |
308 | The | |
309 | .IR arguments , | |
10427eb2 | 310 | ppif any, |
e29834b8 MW |
311 | are still made available to the evaluated forms and loaded files. |
312 | . | |
313 | .SS "Operation" | |
314 | The | |
315 | .B runlisp | |
316 | program behaves as follows. | |
10427eb2 MW |
317 | . |
318 | .hP 1. | |
e29834b8 MW |
319 | The first thing it does is parse its command line. |
320 | Options must precede positional arguments, | |
321 | though the boundary may be marked explicitly using | |
322 | .RB ` \-\- ' | |
323 | if desired. | |
324 | If the command line contains any of | |
325 | .RB ` \-e ', | |
326 | .RB ` \-l ', | |
327 | or | |
328 | .RB ` \-p ', | |
329 | then | |
330 | .B runlisp | |
331 | treats all of its positional arguments as | |
332 | .I arguments | |
333 | to provide to the given forms and files, | |
334 | and runs in | |
335 | .I eval | |
336 | mode; | |
337 | otherwise, the first positional argument becomes the | |
338 | .I script | |
339 | name, the remaining ones become | |
340 | .IR arguments , | |
341 | and | |
342 | .B runlisp | |
343 | runs in | |
344 | .I script | |
345 | mode. | |
10427eb2 | 346 | .hP 2. |
e29834b8 MW |
347 | In |
348 | .I script | |
349 | mode, | |
350 | .B runlisp | |
351 | reads the second line of the script file, | |
352 | and checks to see if it contains the string | |
353 | .RB ` @RUNLISP: '. | |
354 | If so, then the following text is parsed | |
355 | for | |
356 | .IR "embedded options" , | |
357 | as follows. | |
10427eb2 MW |
358 | .RS |
359 | .PP | |
e29834b8 MW |
360 | The text is split into words |
361 | separated by sequences of whitespace characters. | |
362 | Whitespace, | |
363 | and other special characters, | |
364 | can be included in a word by | |
365 | .I quoting | |
366 | or | |
367 | .IR escaping . | |
368 | Text between single quotes | |
369 | .BR ' ... ' | |
370 | is included literally, without any further interpretation; | |
371 | text between double quotes | |
372 | .BR """" ... """" | |
373 | is treated literally, | |
374 | except that escaping can still be used | |
375 | to escape (e.g.) double quotes and the escape character itself. | |
376 | Outside of single quotes, a backslash | |
377 | .RB ` \e ' | |
378 | causes the following character to be included in a word | |
379 | regardless of its usual meaning. | |
380 | (None of this allows a newline character | |
381 | to be included in a word: | |
382 | this is simply not possible.) | |
383 | A word which is | |
384 | .RB ` \-\- ' | |
385 | before processing quoting and escaping | |
386 | marks the end of embedded options. | |
387 | As a concession to Emacs users, | |
388 | if the sequence | |
389 | .RB ` \-*\- ' | |
390 | appears at the start of a word | |
391 | before processing quoting and escaping, | |
392 | then everything up to and including the next occurrence of | |
393 | .RB ` \-*\- ' | |
394 | is ignored. | |
10427eb2 | 395 | .PP |
e29834b8 MW |
396 | The resulting list of words |
397 | is processed as if it held further command-line options. | |
10427eb2 MW |
398 | Currently, only |
399 | .RB ` \-D ' | |
400 | and | |
401 | .RB ` \-L ' | |
402 | options are permitted in embedded option lists: | |
403 | .RB ` \-h ' | |
404 | and | |
405 | .RB ` \-v ' | |
406 | are clearly only useful in interactive use; | |
407 | setting | |
408 | .RB ` \-q ' | |
409 | or | |
410 | .RB ` \-v ' | |
411 | would just be annoying; | |
412 | setting | |
413 | .RB ` \-c ' | |
414 | or | |
415 | .RB ` \-o ' | |
416 | would override the user's command-line settings; | |
417 | it's clearly too late to set | |
418 | .RB ` \-E '; | |
419 | and | |
e29834b8 MW |
420 | .B runlisp |
421 | is now committed to | |
422 | .I script | |
10427eb2 | 423 | mode, so it's too late for |
e29834b8 MW |
424 | .RB ` \-e ', |
425 | .RB ` \-l ', | |
426 | and | |
427 | .RB ` \-p ' | |
10427eb2 MW |
428 | too. |
429 | .PP | |
e29834b8 MW |
430 | (This feature allows scripts to provide options even if they use |
431 | .BR env (1) | |
432 | to find | |
433 | .B runlisp | |
434 | on the | |
435 | .BR PATH , | |
436 | or to provide more than one option, | |
437 | since many operating systems pass the text following | |
438 | the interpreter name on a | |
439 | .RB ` #! ' | |
440 | line as a single argument, without further splitting it at spaces.) | |

443 | .hP 3. | |
444 | If no | |
445 | .RB ` \-c ' | |
446 | options were given, | |
447 | then the default configuration files are read: | |
448 | the system configuration from | |
449 | .B @etcdir@/runlisp.conf | |
e29834b8 | 450 | and |
10427eb2 MW |

455 | .BR ~/.config/runlisp.conf : | |
456 | see | |

e29834b8 MW |
461 | The list of |
462 | .I "acceptable Lisp implementations" | |
463 | is determined. | |
464 | If any | |
465 | .RB ` \-L ' | |
10427eb2 | 466 | options have been found, |
e29834b8 MW |
467 | then the list of acceptable implementations |
468 | consists of all of the implementations mentioned in | |

e29834b8 MW |
470 | options |
471 | in any of the places | |
472 | .B runlisp | |
473 | looked for options, | |
474 | in the order of their first occurrence. | |
475 | (If an implementation is named more than once, | |
476 | then | |
477 | .B runlisp | |
478 | prints a warning to stderr | |
479 | and ignores all but the first occurrence.) | |
480 | If no | |
481 | .RB ` \-L ' | |
482 | option is given, then | |
483 | .B runlisp | |
484 | uses a default list, | |
10427eb2 MW |
485 | which consists of all of the Lisp implementations |
486 | defined in its configuration, | |
487 | in the order in which they were defined. | |
488 | . | |
489 | .hP 5. | |
e29834b8 MW |
490 | The list of |
491 | .I "preferred Lisp implementations" | |
492 | is determined. | |
10427eb2 MW |
493 | If the environment variable |
494 | .B RUNLISP_PREFER | |
495 | is set, | |
496 | then its value should be a list of names of Lisp implementations | |
497 | separated by a comma and/or one or more whitespace characters. | |
498 | Otherwise, if there is a setting for the variable | |
499 | .B prefer | |
500 | in the | |
501 | .B @CONFIG | |
502 | configuration section, | |
503 | then its (expanded) value should be a list of Lisp implementations, | |

518 | Acceptable Lisp implementations are tried in turn. |
519 | First, the preferred implementations | |
520 | which are also listed as acceptable implementations | |
521 | are tried, in the order in which they appear | |
522 | in the preferred implementations list; | |

524 | in the order in which they appear | |
525 | in the acceptable implementations list. | |

526 | .RS |
527 | .PP | |
528 | A Lisp implementation is defined by a configuration section | |
529 | which defines a variable | |
530 | .BR run-script . | |
531 | The name of the configuration section | |
532 | is the name of the Lisp implementation, | |
533 | as used in the acceptable and preferred lists described above. | |
534 | .hP (a) | |
535 | The variable | |
536 | .B image-file | |
537 | is looked up in the configuration section. | |
538 | If a value is found, then | |
539 | .B runlisp | |
540 | looks up and expands | |
541 | .BR image-path , | |
542 | and checks to see if a file exists with the resulting name. | |
543 | If so, it sets the variable | |
544 | .B @image | |
545 | to | |
546 | .B t | |
547 | in the configuration section. | |
548 | .hP (b) | |
549 | The variable | |
550 | .B run-script | |
551 | is expanded and word-split. | |
552 | The | |
553 | .I script | |
554 | (an internal script, in | |
555 | .I eval | |
556 | mode) | |
557 | and | |
558 | .IR argument s | |
559 | are appended, and | |
560 | the entire list is passed to the | |
e29834b8 MW |
561 | .BR execvp (3) |
562 | function. | |
563 | If that succeeds, the Lisp implementation runs; | |
564 | if it fails with | |
565 | .B ENOENT | |
566 | then other Lisp systems are tried; | |
567 | if it fails with some other error, then | |
568 | .B runlisp | |
569 | reports an error message to stderr | |
570 | and exits unsuccessfully | |
571 | (with code 127). | |
572 | If the | |
573 | .RB ` \-n ' | |
574 | option was given, then | |
575 | .B runlisp | |
576 | just simulates the behaviour of | |
577 | .BR execvp (3), | |
578 | printing messages to stderr | |
579 | if the verbosity level is sufficiently high, | |
580 | and exits. | |

582 | .SS "Script environment" | |
10427eb2 MW |
583 | Many Lisp implementations don't provide a satisfactory environment |
584 | for scripts to run in. | |
585 | The actual task of invoking a Lisp implementation | |
586 | is left to configuration, | |
587 | but the basic configuration supplied with | |
e29834b8 | 588 | .B runlisp |
10427eb2 | 589 | ensures the following facts about their environment. |
e29834b8 MW |
590 | .hP \*o |
591 | The keyword | |
592 | .B :runlisp-script | |
593 | is added to the | |
594 | .B *features* | |
595 | list if | |
596 | .B runlisp | |
597 | is running in | |
598 | .I script | |
599 | mode. | |
600 | .hP \*o | |
601 | Most Lisp systems support a user initialization file | |
602 | which they load before entering the REPL; | |
603 | some also have a system initialization file. | |
604 | The | |
605 | .B runlisp | |
606 | program arranges | |
607 | .I not | |
608 | to read these files, | |
609 | so that the Lisp environment is reasonably predictable, | |
610 | and to avoid slowing down script startup | |
611 | with things which are convenient for use in an interactive session, | |
612 | but can't be relied upon by a script anyway. | |
613 | .hP \*o | |
614 | The Unix standard input, standard output, and standard error files | |
615 | are available through the Lisp | |
616 | .BR *standard-input* , | |
617 | .BR *standard-output* , | |
618 | and | |
619 | .BR *error-output* | |
620 | streams, respectively. | |
621 | .hP \*o | |
622 | Both | |
623 | .B *compile-verbose* | |
624 | and | |
625 | .B *load-verbose* | |
626 | are set to nil. | |
627 | On CMU\ CL, | |
628 | .B ext:*require-verbose* | |
629 | is also nil. | |
630 | Alas, this is insufficient to muffle noise while loading add-on systems | |
631 | on some implementations. | |
632 | .hP \*o | |
633 | If an error is signalled, and not caught by user code, | |
634 | then the process will print a message to stderr | |
635 | and exit with a nonzero status. | |
636 | The reported message may be a long, ugly backtrace, | |
637 | or a terse error report. | |
638 | If no error is signalled but not caught, | |
639 | then the process will exit with status 0. | |
640 | .hP \*o | |
641 | The initial package is | |
642 | .BR COMMON-LISP-USER , | |
643 | which has no symbols `present' (i.e., imported or interned). | |
644 | .hP \*o | |
645 | The | |
646 | .B asdf | |
647 | and | |
648 | .B uiop | |
649 | systems are already loaded. | |
650 | Further systems can be loaded using | |
651 | .B asdf:load-system | |
652 | as usual. | |
653 | The script name | |
654 | (which is only meaningful if | |
655 | .B runlisp | |
656 | is in | |
657 | .I script | |
658 | mode, obviously) | |
659 | and arguments are available through the | |
660 | .B uiop:argv0 | |
661 | function and | |
662 | .B uiop:*command-line-arguments* | |
663 | variable, respectively. | |

668 | .hP \*o |
669 | Loading ASDF systems is irritatingly noisy | |
670 | with some Lisp implementations. | |
671 | Suggestions for how to improve this are welcome. | |
672 | .hP \*o | |
673 | More Lisp implementations should be supported. | |
674 | I've supported the ones I have installed. | |
675 | I'm not willing to put a great deal of effort into supporting | |
676 | non-free Lisp implementations; | |
677 | but help supporting free Lisps is much appreciated. | |
678 | .hP \*o | |
679 | The protocol for passing the script name through to | |
680 | .B uiop | |
681 | (specifically, through the | |
682 | .B __CL_ARGV0 | |
683 | environment variable) | |
684 | is terribly fragile, | |
685 | but supporting | |
686 | .B uiop | |
687 | is obviously a better approach than introducing a | |
688 | .BR runlisp -specific | |
689 | interface to the same information. | |
690 | I don't know how to fix this: | |
691 | suggestions are welcome. | |
