This lesson gets you started with re2c. In the end you will have an easy UPN
calculator for use at command line.

-Then use your compiler to compile that code and run it.
+Then use your compiler to compile that code and run it. If you are using gcc
+you simply do the following:
+
+ gcc -o test.o test.c
+ ./test.o <input_file_name>
+
+If you are using windows you might want to read till the end of this lesson.
When you want to debug the code it helps to make re2c generate working #line
information. To do so you simply specify the output file using the -o switch
switch also contains the -s behavior.
re2c -b -o test.c calc_007.b.re

+
+For windows users Lynn Allen provided some additional stuff to get you started
+in the Microsoft world. This addon resides in the windows subdirectory and
+gives you something to expereiment with. The code in that directory is based
+on the first step and has the following changes:
+
+* vc6 .dsp/.dsw and vc7/vc8 .sln/.vcproj project files that have "Custom Build
+Steps" that can tell when main.re changes, and know how to generate main.c
+from main.re. They assume that you unpacked the zip package and have re2c
+itself build or installed in Release and Release-2005 directory respectively.
+If re2c cannot be found you need to modify the custom build step and correct
+the path to re2c.
+
+* BuildAndRun.bat to do command line rec2 and then cl and then run the
+executable (discontinues with message if errors).
+
+* built-in cppunit-like test to confirm it worked as expected.
+
+* array of test strings "fed" to scan rather than file contents to facilitate
+testing and also reduce the newbie learning curve.
+
+* HiResTimer output for 10,000 loops and 100,000 loops. While this might be
+excessive for this lesson, it illustrates how to do it for subsequent lessons
+and your own stuff using windows. Also it shows that Release build is as fast
+as strncmp for this test and can probably be made significantly faster.
+
+* If you want to build the other steps of this lesson using windows tools
+simply copy the *.re files into the windows directory as main.re and rebuild.

+/*!ignore:re2c
+
+- basic interface for string reading
+
+ . We define the macros YYCTYPE, YYCURSOR, YYLIMIT, YYMARKER, YYFILL
+ . YYCTYPE is the type re2c operates on or in other words the type that
+ it generates code for. While it is not a big difference when we were
+ using 'unsigned char' here we would need to run re2c with option -w
+ to fully support types with sieof() > 1.
+ . YYCURSOR is used internally and holds the current scanner position. In
+ expression handlers, the code blocks after re2c expressions, this can be
+ used to identify the end of the token.
+ . YYMARKER is not always being used so we set an initial value to avoid
+ a compiler warning.
+ . YYLIMIT stores the end of the input. Unfortunatley we have to use strlen()
+ in this lesson. In the next example we see one way to get rid of it.
+ . We use a 'for(;;)'-loop around the scanner block. We could have used a
+ 'while(1)'-loop instead but some compilers generate a warning for it.
+ . To make the output more readable we use 're2c:indent:top' scanenr
+ configuration that configures re2c to prepend a single tab (the default)
+ to the beginning of each output line.
+ . The following lines are expressions and for each expression we output the
+ token name and continue the scanner loop.
+ . The second last token detects the end of our input, the terminating zero in
+ out input string. In other scanners detecting the end of input may vary.
+ For example binary code may contain \0 as valid input.
+ . The last expression accepts any input character. It tells re2c to accept
+ the opposit of the empty range. This includes numbers and our tokens but
+ as re2c goes from top to botton when evaluating the expressions this is no
+ problem.
+ . The first three rules show that re2c actually prioritizes the expressions
+ from top to bottom. Octal number require a starting "0" and the actual
+ number. Normal numbers start with a digit greater 0. And zero is finally a
+ special case. A single "0" is detected by the last rule of this set. And
+ valid ocal number is already being detected by the first rule. This even
+ includes multi "0" sequences that in octal notation also means zero.
+ Another way would be to only use two rules:
+ "0" [0-9]+
+ "0" | ( [1-9] [0-9]* )
+ A full description of re2c rule syntax can be found in the manual.

+001_upn_calculator
+
+ This lesson gets you started with re2c. In the end you will have an easy UPN
+ calculator for use at command line.
+
+ You will learn about the basic interface of re2c when scanning input strings.
+ How to detect the end of the input and use that to stop scanning in order to
+ avoid problems.
+
+ The lesson also contains a windows subdirectory to get you started in the
+ Microsoft world.
+
+002_strip_comments
+
+ In this lesson you will learn how to use multiple scanner blocks and how to
+ read the input from a file instead of a zero terminated string. In the end you
+ will have a scanner that filters comments out of c source files but keeps re2c
+ comments.
