STRING-EXT String + extensions
The basic words for handling string buffers. There are
much more buffer words used in most Forth implementations around
but they can usually implemented as colon-word quite effectivly
on the basis of the STRING wordset.
-TRAILING ( str-ptr str-len -- str-ptr str-len' )
- ansi 17.6.1.0170
check the given buffer if it contains whitespace at its end.
If so, shorten str-len to meet the last non-whitespace
character in the buffer.
reference: p4_dash_trailing in ../src/string.c:0038, export CO -TRAILING
-
/STRING
- ansi 17.6.1.0245
no forth documentation available (p4_slash_string)
- see the ANSI Documentation of this word : ansi 17.6.1.0245
reference: p4_slash_string in ../src/string.c:0048, export CO /STRING
BLANK ( str-ptr str-len -- )
- ansi 17.6.1.0780
FILL a given buffer with BL blanks
reference: p4_blank in ../src/string.c:0066, export CO BLANK
CMOVE ( from-ptr to-ptr len -- )
- ansi 17.6.1.0910
memcpy an area from->to for len bytes, starting at
the lower addresses, see CMOVE>
reference: p4_cmove in ../src/string.c:0076, export CO CMOVE
CMOVE> ( from-ptr to-ptr len -- )
- ansi 17.6.1.0920
memcpy an area from->to for len bytes, starting
with the higher addresses, see CMOVE
reference: p4_cmove_up in ../src/string.c:0091, export CO CMOVE>
COMPARE ( str-ptr1 str-len1 str-ptr2 str-len2 -- n )
- ansi 17.6.1.0935
compare both str-buffers, return 0 if they are equal,
-1 if lower or shorter, and 1 if greater or longer
reference: p4_compare in ../src/string.c:0108, export CO COMPARE
SEARCH ( str-ptr1 str-len1 str-ptr2 str-len2 -- str-ptr1' str-len1' flag )
- ansi 17.6.1.2191
search the str-buffer1 for the text of str-buffer2,
if it is contained return TRUE and return buffer-values that
point to the contained string, otherwise return FALSE and
leave the original str-buffer1.
reference: p4_search in ../src/string.c:0133, export CO SEARCH
SLITERAL ( -- string ) (runtime) compile-only
- smart-word ansi 17.6.1.2212
this word does almost the same as LITERAL - it takes
an S" string as specified in the CS-STACK at compile
time and compiles into the current definition where it is
returned as if there were a direct string-literal. This
can be used to compute a string-literal at compile-time
and hardwire it.
example:
: ORIGINAL-HOME [ $HOME COUNT ] SLITERAL ; ( -- str-ptr str-len )
reference: p4_sliteral in ../src/string.c:0158, export CS SLITERAL
