I don't know about better ... but you could create a c function that evaluates strings (ala perlembed):
#include <EXTERN.h> #include <perl.h> static PerlInterpreter *my_perl; SV* my_eval_sv(SV *sv, I32 croak_on_error) { dSP; SV* retval; STRLEN n_a; PUSHMARK(SP); eval_sv(sv, G_SCALAR); SPAGAIN; retval = POPs; PUTBACK; if (croak_on_error && SvTRUE(ERRSV)) croak(SvPVx(ERRSV, n_a)); return retval; } main (int argc, char **argv, char **env) { STRLEN n_a; char *embedding[] = { "", "-e", "0" }; SV *var, *cmd; my_perl = perl_alloc(); perl_construct( my_perl ); perl_parse(my_perl, NULL, 3, embedding, NULL); perl_run(my_perl); var = newSVpvf( "%s", "ybred" ); printf( "var is %s\n", SvPV(var,n_a) ); cmd = newSVpvf( "reverse('%s');", SvPV(var,n_a) ); var = my_eval_sv( cmd, TRUE ); printf( "var is %s\n", SvPV(var,n_a) ); perl_destruct(my_perl); perl_free(my_perl); }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
