2015-12-17Minor improvement in wordsplit.Sergey Poznyakoff2
* src/wordsplit.h (WRDSX_WORD, WRDSX_QUOTE): New defines. * src/wordsplit.c: Use them when initializing ws_escape.
2015-12-17Update copyright yearsSergey Poznyakoff124
2015-12-17wordsplit: fix ws trimming and return_delim optionSergey Poznyakoff2
* src/wordsplit.c (_WSNF_DELIM): New node flag (wsnode_flagstr): Print 'd' for that flag. (expvar): Don't set WRDSF_WS when expanding variable value. This fixes, e.g., expansion of a$x if x begins with a whitespace. (wsnode_nullelim): A _WSNF_DELIM node breaks join chain. (wordsplit_trimws): Don't affect nodes within join chains. (scan_word): Set _WSNF_DELIM for returned delimiters. * tests/wordsplit.at (TESTWSP): 8th argument - prologue shell code. Use it to unset environment variables in env/getenv tests. Test ws elimination with return_delims set.
