Firstly, we use the |kpse_web_format| when opening input files, which triggers the inspection of the \.{WEBINPUTS} environment variable. Secondly, we set |kpse_program_name| to `\.{tie}'. This means if the variable \.{WEBINPUTS.tie} is present in \.{texmf.cnf} (or \.{WEBINPUTS\_tie} in the environment) its value will be used as the search path for filenames. This allows different flavors of \.{TIE} (or other \.{WEB} programs) to have different search paths.@.WEBINPUTS@> In all, the directories to be searched for come from at least two sources: \smallskip {\parindent1.5em \item{(a)} a user-set environment variable \.{WEBINPUTS} (overridden by \.{WEBINPUTS\_tie}); \item{(b)} a line in \Kpathsea/ configuration file \.{texmf.cnf},\hfil\break e.g., \.{WEBINPUTS=\$TEXMFDOTDIR:\$TEXMF/texmf/web//}\hfil\break or \.{WEBINPUTS.tie=\$TEXMFDOTDIR:\$TEXMF/texmf/web//}.\par} \smallskip Note that, although \.{WEBINPUTS} might suggest otherwise, \.{TIE} is more or less language-agnostic and that it is perfectly capable of handling \.{CWEB} files as input as well, as long as the ``change files'' adhere to the general \.{@@x}, \.{@@y}, \.{@@z} convention. @z @x l.1236 main(argc,argv) int argc; string *argv; @y int main (int argc, string *argv) @z @x l.1241 print_ln(banner); /* print a ``banner line'' */ print_ln(copyright); /* include the copyright notice */ @y kpse_set_program_name(argv[0], "tie"); print(banner); /* print a ``banner line'' */ print_ln(versionstring); /* Web2C version */ print_ln(copyright); /* include the copyright notice */ @z Section 60 @x l.1256 -- fix typo Additionaly we report the history to the user, although this may not @y Additionally we report the history to the user, although this may not @z @x l.1261 -- rewrite error reporting @= {string msg; switch (history) { case spotless: msg="No errors were found"; break; case troublesome: msg="Pardon me, but I think I spotted something wrong."; break; case fatal: msg="That was a fatal error, my friend"; break; } /* there are no other cases */ print2_nl("(%s.)",msg); term_new_line; exit ( history == spotless ? 0 : 1 ); } @y @= { switch (history) { case spotless: print2_nl("(%s.)", "No errors were found"); term_new_line; break; case troublesome: new_line(stderr); fprintf(stderr, "(Pardon me, but I think I spotted something wrong.)"); new_line(stderr); break; case fatal: default: /* Anything except spotless, troublesome, or fatal is a bug. */ new_line(stderr); fprintf(stderr, "(That was a fatal error, my friend.)"); new_line(stderr); break; } exit ( history == spotless ?
