/** @page awk AWK
@section awk-content CONTENTS
- @ref awk-intro "INTRODUCTION"
@section awk-intro INTRODUCTION
QSEAWK is an AWK interpreter and is a part of the @ref qse_intro "QSE" library.
Its design focuses on building a flexible and robust embedding API with minimal
platform dependency. An embedding application is capable of:
- adding new global variables and functions.
- getting and set the value of a global variable.
- calling a function with or without parameters and getting its return value.
- customizing I/O handlers for file, pipe, console I/O.
- creating multiple interpreters independent of each other.
- running a single script with different I/O streams independently.
- changing language features by setting options.
- and more
The library implements AWK in multiple levels:
- base interpreter
- standard interpreter
- parallel interpreter
The base interpreter provides most core language features while minimizing
platform dependence. When working with the base interpreter, you're required
to write primtive operation handlers like I/O and pass them in to make it
useful. The standard interpreter is usable immediately since it implements
all the primitive operations required by the base interpreter and adds
standard AWK functions. The parallel interpreter enables parallel processing
by adding various MPI variables and functions to the standard interpreter.
Embedding a standard interpreter typically involves the following steps.
- open a new interpreter
- parse in a source script
- open a new runtime context
- execute pattern-action blocks or call a function
- close the runtime context
- close the interpter
The code example below demonstrates the steps in C. It executes the one liner
<b>BEGIN { print "hello, world" }</b>.
@code
/* cc -o hello hello.c -lqseawk -lqsecmn -lm */
#include <qse/awk/std.h>
#include <qse/cmn/stdio.h>
#define FAIL(msg) do { qse_printf(QSE_T("ERR: %s\n"),msg); goto oops; } while(0)
int main ()
{
qse_awk_t* awk = QSE_NULL;
qse_awk_rtx_t* rtx = QSE_NULL;
qse_awk_val_t* retv;
qse_awk_parsestd_t psin;
int ret = -1;
awk = qse_awk_openstd (0); /* open a new interpreter */
if (!awk) FAIL ("cannot open awk");
/* parse the hello world script from a string */
psin.type = QSE_AWK_PARSESTD_STR;
psin.u.str.ptr = QSE_T("BEGIN { print \"hello, world\" }");
psin.u.str.len = qse_strlen(psin.u.str.ptr);
if (qse_awk_parsestd (awk, &psin, QSE_NULL) <= -1)
FAIL (qse_awk_geterrmsg(awk));
rtx = qse_awk_rtx_openstd ( /* open a runtime context */
awk, 0, /* no extension */
QSE_T("hello"), /* ARGV[0] */
QSE_NULL, /* stdin */
QSE_NULL, /* stdout */
QSE_NULL /* default cmgr */
);
if (!rtx) FAIL (qse_awk_geterrmsg(awk));
/* exeucte pattern-action blocks */
retv = qse_awk_rtx_loop (rtx);
if (!retv) FAIL (qse_awk_rtx_geterrmsg(rtx));
qse_awk_rtx_refdownval (rtx, retv); /* destroy the return value */
ret = 0;
oops:
if (rtx) qse_awk_rtx_close (rtx); /* close the runtime context */
if (awk) qse_awk_close (awk); /* close the interpreter */
return ret;
}
@endcode
Things can get simpler when you use C++ API. Note that the C++ API supports
1 single runtime context for each interpreter.
@code
/* c++ -o hello hello.cpp -lqseawkxx -lqseawk -lqsecmnxx -lqsecmn -lm */
#include <qse/awk/StdAwk.hpp>
#include <iostream>
#ifdef QSE_CHAR_IS_MCHAR
# define xcout std::cout
#else
# define xcout std::wcout
#endif
struct MyAwk: public QSE::StdAwk { ~MyAwk () { QSE::StdAwk::close (); } };
#define FAIL(awk) do { \
xcout << QSE_T("ERR: ") << awk.getErrorMessage() << std::endl; \
return -1; \
} while (0)
int main (int argc, char* argv[])
{
MyAwk awk;
// open a new interpreter
if (awk.open () <= -1) FAIL (awk);
// set ARGV[0]
if (awk.addArgument (QSE_T("hello")) <= -1) FAIL (awk);
// parse the source script string
MyAwk::SourceString in(QSE_T("BEGIN { print \"hello, world\" }"));
if (awk.parse (in, MyAwk::Source::NONE) == QSE_NULL) FAIL (awk);
// execute pattern-action blocks.
MyAwk::Value r;
if (awk.loop (&r) <= -1) FAIL (awk);
return 0;
}
@endcode
This library also provides a stand-alone AWK interpreter that you can use
in a console environment. The source code is located under the
<project-root>/cmd/awk subdirectory. See the usage below.
@code
$ qseawk
USAGE: qseawk [options] -f sourcefile [ -- ] [datafile]*

the pattern-action loop
-f/--file sourcefile set the source script file
-d/--deparsed-file deparsedfile set the deparsing output file
-F/--field-separator string set a field separator(FS)
-v/--assign var=value add a global variable with a value
-m/--memory-limit number limit the memory usage (bytes)
-X number fail the number'th memory allocation
