2022-01-04rc: only have single instance of a symbol, extern in header (thanks mcf)cinap_lenrek
2021-12-31rc: fix everythingcinap_lenrek
Untangle the lexer and interpreter thread state. Fix the file and line number error reporting, getting rid of Xsrcfile instruction, as the whole code block can only come from a single file, stuff the source file in slot[1] of the code block instead. Remove limitations for globber (path element limits) and be more intelligent about handling globbing by inserting Xglob instruction only when needed and not run it over every Xsimple argument list. Remove fragile ndot magic and make it explicit by adding the -q flag to . builtin command. Add -b flag for full compilation. Make exitnext() smart, so we can speculate thru rcmain and avoid the fork(). Get rid of all print(2) format functions and use io instead. Improve the io library, adding rstr() to handle tokenization, which allows us to look ahead in the already read buffer for the terminators, avoiding alot of string copies. Auto indent pcmd(), to make line number reporting more usefull. Implement here documents properly, so they can work everywhere.
2014-07-23rc: fix slow Xqdol(), avoid recursion in conclist(), estrdup(), avoid copyingcinap_lenrek
Xqdol() used to take quadratic time because of strcat(), the code isnt really needed as list2str() aready does the same thing in linear time without the strcat(). add estrdup() which uses emalloc() so allocation error are catched. move strdups() of name from callers into newvar(). avoid recursion of conclist(), and avoid copying of word strings by providing Newword() function which doesnt copy the word string.
