* doc-lookup: ignore BROWSER when empty.Paul A. Patience2021-07-101-8/+8
| | | | | | | | | * stdlib/doc-lookup.tl (open-url): Treat empty BROWSER variable as if it were unset (i.e., ignore it). Otherwise the doc function silently fails rather than falling back to alternative URL-opening methods. * txr.1: Documented.
* doc-lookup: add support for OpenBSD.Paul A. Patience2021-07-051-2/+3
| | | | | * stdlib/doc-lookup.tl (os-symbol): Add case for OpenBSD. (open-url): Same.
* genman, lib, tests: use defvarl where possible.Paul A. Patience2021-07-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * genman.txr (dupes, tagnum): Replace defvar with defvarl. * stdlib/doc-lookup.tl (os-symbol): Same. * tests/011/macros-3.tl (x): Same. * tests/011/mandel.txr (x-centre, y-centre, width, i-max, j-max, n) (r-max, pixel-size, x-offset, y-offset): Same. (file, colour-max): Delete (unused) variables. * tests/012/circ.tl (x): Replace defvar with defvarl. * tests/012/stack.tl (stack-limited): Same. * tests/012/struct.tl (s): Same. * tests/013/maze.tl (vi, pa, sc): Delete variables. Use function arguments instead. (usage): Fix typo. * tests/014/dgram-stream.tl (family): Rename to... (*family*): ...this. * tests/014/socket-basic.tl (socktype): Rename to... (*socktype*): ...this. (%iters%): Replace defvar with defvarl.
* doc-lookup: use BROWSER variable; provide fallback.Kaz Kylheku2021-06-291-3/+13
| | | | | | | | | * stdlib/doc-lookup.tl (open-url): On non-Windows platforms, search for a program specified by the BROWSER variable, then by the URL-opening utility, and finally thorugh a fallback list of browsers. * txr.1: Documentation updated.
* doc-lookup: handle xdg-open not terminating.Kaz Kylheku2021-06-291-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | It is common for web browsers like firefox not to fork themselves into the background when initially run from the command line. Only when an additional instance is executed does that instance terminate immediately, passing the URL to the existing instance. (Which also does not constitute forking into the background, but does have the effect of an immediate exit.) User Paul A. Patience reports that some installations of xdg-open have the isssue of not handling this situation; these versions of xdg-open wait for the browser to terminate, which causes xdg-open to hang until the browser is closed if it is the initial instance. * stdlib/doc-lookup.tl (detached-run): New function. Like run, but forks into the background, running the process in a detached grandchild whose parent terminates, so that it becomes an orphan parented to the init daemon. We redirect *stdout* to *stdnull* because the first instance of the browser can spit ugly, meaningless diagnostics when it terminates. (open-url): Use detached-run instad of run. Don't check the return value for zero; there is no integer exit status.
* doc-lookup: *doc-url* variable must be dynamic.Kaz Kylheku2021-06-281-1/+1
| | | | | * stdlib/doc-lookup.tl (*doc-url*): Define with defvar, not defvarl. Problem reported by Paul A. Patience.
* file layout: moving share/txr/stdlib to stdlib.Kaz Kylheku2021-06-241-0/+49
This affects run-time also. Txr installations where the executable is not in directory ending in ${bindir} will look for stdlib rather than share/txr/stdlib, relative to the determined installation directory. * txr.c (sysroot_init): If we detect relative to the short name, or fall back on the program directory, use stdlib rather than share/txr/stdlib as the stdlib_path. * INSTALL: Update some installation notes not to refer to share/txr/stdlib but stdlib. * Makefile (STDLIB_SRCS): Refer to stdlib, not share/txr/stdlib. (clean): In unconfigured mode, remove the old share/txr/stdlib entirely. Remove .tlo files from stdlib. (install): Install lib materials from stdlib. * txr.1: Updated documentation under Deployment Directory Structure. * share/txr/stdlib/{asm,awk,build,cadr}.tl: Renamed to stdlib/{asm,awk,build,cadr}.tl. * share/txr/stdlib/{compiler,conv,copy-file,debugger}.tl: Renamed to stdlib/{compiler,conv,copy-file,debugger}.tl. * share/txr/stdlib/{defset,doc-lookup,doc-syms,doloop}.tl: Renamed to stdlib/{defset,doc-lookup,doc-syms,doloop}.tl. * share/txr/stdlib/{each-prod,error,except,ffi}.tl: Renamed to stdlib/{each-prod,error,except,ffi}.tl. * share/txr/stdlib/{getopts,getput,hash,ifa}.tl: Renamed to stdlib/{getopts,getput,hash,ifa}.tl. * share/txr/stdlib/{keyparams,match,op,optimize}.tl: Renamed to stdlib/{keyparams,match,op,optimize}.tl. * share/txr/stdlib/{package,param,path-test,pic}.tl: Renamed to stdlib/{package,param,path-test,pic}.tl. * share/txr/stdlib/{place,pmac,quips,save-exe}.tl: Renamed to stdlib/{place,pmac,quips,save-exe}.tl. * share/txr/stdlib/{socket,stream-wrap,struct,tagbody}.tl: Renamed to stdlib/{socket,stream-wrap,struct,tagbody}.tl. * share/txr/stdlib/{termios,trace,txr-case,type}.tl: Renamed to stdlib/{termios,trace,txr-case,type}.tl. * share/txr/stdlib/{ver,vm-param,with-resources,with-stream}.tl: Renamed to stdlib/{ver,vm-param,with-resources,with-stream}.tl. * share/txr/stdlib/yield.tl: Renamed to stdlib/yield.tl. * share/txr/stdlib/{txr-case,ver}.txr: Renamed to stdlib/{txr-case,ver}.txr. * gencadr.txr: Update to stdlib/place.tl. * genman.txr: Update to stdlib/cadr.tl.
