We don't + want to use the assuan library because we don't want to hide errors + in that library. + + The script language is line based. Empty lines or lines containing + only white spaces are ignored, line with a hash sign as first non + white space character are treated as comments. + + A simple macro mechanism is implemnted. Macros are expanded before + a line is processed but after comment processing. Macros are only + expanded once and non existing macros expand to the empty string. + A macro is dereferenced by prefixing its name with a dollar sign; + the end of the name is currently indicated by a white space, a + dollar sign or a slash. To use a dollor sign verbatim, double it. + + A macro is assigned by prefixing a statement with the macro name + and an equal sign. The value is assigned verbatim if it does not + resemble a command, otherwise the return value of the command will + get assigned. The command "let" may be used to assign values + unambigiously and it should be used if the value starts with a + letter. + + Conditions are not yes implemented except for a simple evaluation + which yields false for an empty string or the string "0". The + result may be negated by prefixing with a '!'. + + The general syntax of a command is: + + [ =] [] + + If NAME is not specifed but the statement returns a value it is + assigned to the name "?" so that it can be referenced using "$?". + The following commands are implemented: + + let + Return VALUE. + + echo + Print VALUE. + + openfile + Open file FILENAME for read access and return the file descriptor. + + createfile + Create file FILENAME, open for write access and return the file + descriptor. + + pipeserver + Connect to the Assuan server PROGRAM. + + send + Send LINE to the server. + + expect-ok + Expect an OK response from the server. Status and data out put + is ignored. + + expect-err + Expect an ERR response from the server. Status and data out put + is ignored. + + count-status + Initialize the assigned variable to 0 and assign it as an counter for + status code CODE. This command must be called with an assignment. + + quit + Terminate the process. + + quit-if + Terminate the process if CONDITION evaluates to true. + + fail-if + Terminate the process with an exit code of 1 if CONDITION + evaluates to true. + + cmpfiles + Returns true when the content of the files FIRST and SECOND match. + + getenv + Return the value of the environment variable NAME. + +*/ + +#include +#include +#include +#include +#include +#include +#include +#include + +#if __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 5 ) +# define ATTR_PRINTF(f,a) __attribute__ ((format (printf,f,a))) +#else +# define ATTR_PRINTF(f,a) +#endif + +#if __STDC_VERSION__ < 199901L +# if __GNUC__ >= 2 && !defined (__func__) +# define __func__ __FUNCTION__ +# else +/* Let's try our luck here.
