A tiny parser to read content of a own config file using pure c and flex library.

$ flex myscanner.l $ cc myscanner.c lex.yy.c $ ls a.out config.in lex.yy.c myscanner.c myscanner.h myscanner.l

Run parser and get contents from config.in file via linux/unix command:

$ ./a.out < config.in 1 db_type is set to mysql 2 db_name is set to testdata 3 db_table_prefix is set to test_ 4 db_port is set to 1099

You can use %option nounput yylineno in lex file.

• Adding fopen() to read yyinput from file
• Using keyName as value (e.g: db_name : db_name)

Feel free to participate and develop.

I saw an lecture from Prof. Jonathan Engelsma and It's encouraged me to do this project myself.
