Usage: pcre2test [options] [<input file> [<output file>]]
Input and output default to stdin and stdout.
If input is a terminal, readline() is used to read from it.
Options:
-8 use the 8-bit library
-16 use the 16-bit library
-32 use the 32-bit library
-ac set default pattern modifier PCRE2_AUTO_CALLOUT
-AC as -ac, but also set subject 'callout_extra' modifier
-b set default pattern modifier 'fullbincode'
-C show PCRE2 compile-time options and exit
-C arg show a specific compile-time option and exit with its
value if numeric (else 0). The arg can be:
backslash-C use of \C is enabled [0, 1]
bsr \R type [ANYCRLF, ANY]
ebcdic compiled for EBCDIC character code [0, 1]
ebcdic-io if compiled for EBCDIC, whether pcre2test's input
and output is EBCDIC or ASCII [0, 1]
ebcdic-nl25 if compiled for EBCDIC, whether NL is 0x25 [0, 1]
jit just-in-time compiler supported [0, 1]
jitusable test JIT usability [0, 1, 2, 3]
linksize internal link size [2, 3, 4]
newline newline type [CR, LF, CRLF, ANYCRLF, ANY, NUL]
pcre2-8 8 bit library support enabled [0, 1]
pcre2-16 16 bit library support enabled [0, 1]
pcre2-32 32 bit library support enabled [0, 1]
unicode Unicode and UTF support enabled [0, 1]
--colo[u]r[=<always,auto,never>]
show output in colour
-d set default pattern modifier 'debug'
-dfa set default subject modifier 'dfa'
-E preprocess input only (#if ... #endif)
-error <n,m,..> show messages for error numbers, then exit
-help show usage information
-i set default pattern modifier 'info'
-jit set default pattern modifier 'jit'
-jitfast set default pattern modifier 'jitfast'
-jitverify set default pattern modifier 'jitverify'
-LM list pattern and subject modifiers, then exit
-LP list non-script properties, then exit
-LS list supported scripts, then exit
-malloc exercise malloc() failures
-q quiet: do not output PCRE2 version number at start
-pattern <s> set default pattern modifier fields
-subject <s> set default subject modifier fields
-S <n> set stack size to <n> mebibytes
-t [<n>] time compilation and execution, repeating <n> times
-tm [<n>] time execution (matching) only, repeating <n> times
-T same as -t, but show total times at the end
-TM same as -tm, but show total time at the end
-unittest run unit tests, then exit
-v|--version show PCRE2 version and exit
Options (31)
| Option | Description | Source |
|---|
-8 | If the 8-bit library has been built, this option causes it to be used (this is the default). | help + man |
-16 | If the 16-bit library has been built, this option causes it to be used. | help + man |
-32 | If the 32-bit library has been built, this option causes it to be used. | help + man |
-ac | Behave as if each pattern has the auto_callout modifier, that is, insert automatic callouts into every pattern that is compiled. | help + man |
-AC | As for -ac, but in addition behave as if each subject line has the callout_extra modifier, that is, show additional information from callouts. | help + man |
-b | Behave as if each pattern has the fullbincode modifier; | help + man |
-C | Output the version number of the PCRE2 library, and all available information about the optional features that are included, and then exit with zero exit code. | help + man |
--colo u]r[=<always | show output in colour | help |
-d | Behave as if each pattern has the debug modifier; | help + man |
-dfa | Behave as if each subject line has the dfa modifier; | help + man |
-E | Run in "preprocess only" mode (similar to "gcc -E"). | help + man |
-error n | show messages for error numbers, then exit | help |
-help | Output a brief summary these options and then exit. | help + man |
-i | Behave as if each pattern has the info modifier; | help + man |
-jit | Behave as if each pattern line has the jit modifier; | help + man |
-jitfast | Behave as if each pattern line has the jitfast modifier; | help + man |
-jitverify | Behave as if each pattern line has the jitverify modifier; | help + man |
-LM | List modifiers: write a list of available pattern and subject modifiers to the standard output, then exit with zero exit code. | help + man |
-LP | List properties: write a list of recognized Unicode properties to the standard output, then exit with zero exit code. | help + man |
-LS | List scripts: write a list of recognized Unicode script names to the standard output, then exit with zero exit code. | help + man |
-malloc | Exercise malloc() failures, by first counting the number of calls made to malloc during pattern compilation and matching, then re-running the compilation and matching that many times, exercising a… | help + man |
-q | Do not output the version number of pcre2test at the start of execution. | help + man |
-pattern s | Behave as if each pattern line contains the given modifiers. | help + man |
-subject s | Behave as if each subject line contains the given modifiers. | help + man |
-S n | On Unix-like systems, set the size of the run-time stack to size mebibytes (units of 10241024 bytes). | help + man |
-t n | Run each compile and match many times with a timer, and output the resulting times per compile or match. | help + man |
-tm n | This is like -t except that it times only the matching phase, not the compile phase. | help + man |
-T -TM | These behave like -t and -tm, but in addition, at the end of a run, the total times for all compiles and matches are output. | help + man |
-TM | same as -tm, but show total time at the end | help |
-unittest | Run a fixed set of additional tests of the PCRE2 API which are not driven by the test input files, and then exit. | help + man |
-version | Output the PCRE2 version number and then exit. (in the manual page but not in --help) | man |
