Legend for the Slurp Benchmark Entries
In all cases below 'FS' or 'F::S' means the current File::Slurp module
is being used in the benchmark. The full name and description will say
which options are being used.
-
+--------------------------------------------------------------------------
These benchmarks write a list of lines to a file. Use the direction option
of 'out' or 'both' and the context option is 'list' or 'both'.
Key Description/Source
- --- ------------------
+ ----- --------------------------
FS::write_file Current F::S write_file
FS::write_file Aref Current F::S write_file on array ref of data
print Open a file and call print() on the list data
- print/join Open a file and call print() on the joined
- list data
+ print/join Open a file and call print() on the joined list
+ data
syswrite/join Open a file, call syswrite on joined list data
- sysopen/syswrite Sysopen a file, call syswrite on joined
- list data
+ sysopen/syswrite Sysopen a file, call syswrite on joined list
+ data
original write_file write_file code from original File::Slurp
(pre-version 9999.*)
+--------------------------------------------------------------------------
+These benchmarks write a scalar to a file. Use the direction option
+of 'out' or 'both' and the context option is 'scalar' or 'both'.
+ Key Description/Source
+ ----- --------------------------
+ FS::write_file Current F::S write_file
+ FS::write_file Sref Current F::S write_file of scalar ref of data

+ data
+ orig_write_file write_file code from original File::Slurp
+ (pre-version 9999.*)
+--------------------------------------------------------------------------
+These benchmarks slurp a file into an array. Use the direction option
+of 'in' or 'both' and the context option is 'list' or 'both'.
+
+ Key Description/Source
+ ----- --------------------------
+ FS::read_file Current F::S read_file - returns array
+ FS::read_file_array_ref Current F::S read_file - returns array
