I have a Perl module called CGI::Github::Webhook whose test suite works fine on Travis CI so far on the branch master . But since it's a module for writing CGI scripts, I wanted to test it with CGI::Test as this would be closer to real-life scenarios. But every Travis CI run in the branch cgi-test failed so far . Except for the runs with Perl 5.24 and above, every failed run contained these lines, just with different Perl version numbers in the paths: Attempt to reload List/Util.pm aborted. Compilation failed in require at /home/travis/perl5/perlbrew/perls/5.22.0/lib/site_perl/5.22.0/Sub

In perl special tokens like __PACKAGE__ , __SUB__ , __FILE__ , __LINE__ exists and available from script. I may get value of __PACKAGE__ from XS as HvNAME( PL_currstash ) , I suppose. But how to access others? Is there special interface to access all of them from XS ? Like: CTX->package , CTX->sub etc. rurban You can look them up one by one in toke.c for the compile-time values: __PACKAGE__ => HvNAME(PL_curstash) or PL_curstname __FILE__ => CopFILE(PL_curcop) (at compile-time) __LINE__ => CopLINE(PL_curcop) (at compile-time) __SUB__ => PL_compcv If you need them at run-time look at the various

I'm working on some code that needs to serialize Perl regexes, including any regex flags. Only a subset of flags are supported, so I need to detect when unsupported flags like /u are in the regex object. The current version of the code does this: static void serialize_regex_flags(buffer *buf, SV *sv) { char flags[] = {0,0,0,0,0,0}; unsigned int i = 0, f = 0; STRLEN string_length; char *string = SvPV(sv, string_length); Then manually processes string char-by-char to find flags. The problem here is that the stringification of regex flags changed (I think in Perl 5.14) from e.g. (?i-xsm:foo) to (

How can I pass Perl array by reference to C XS module? my @array = ( 1..20 ); XSTEST::test_array_passing(\@array); What do I do in XS so it sees the array? XS can receive a ref to ARRAY as either an AV* or an SV* . The latter would have to be dereferenced to an AV* . use Inline C => DATA; @array = (1 .. 20); $r = sum_of_elements1(\@array); $s = sum_of_elements2(\@array); print "$r $s\n"; # produces output: "210 210\n" __END__ __C__ double sum_of_elements1(AV* array) { int i; double sum = 0.0; for (i=0; i<=av_len(array); i++) { SV** elem = av_fetch(array, i, 0); if (elem != NULL) sum += SvNV(

类型参数 表现形式：在名称后面以方括号表示， Array[T] 何处使用 class 中，用于定义变量、入参、返回值 class Pair[T, S](val first: T, val second: S) // scala 可自动推断具体的类型 val p = new Pair(42, "String") // Pair[Int, String] 函数、方法 def getMiddle[T](a: Array[T]) = a(a.length / 2) 类型边界 上边界 T <: UpperBound // 比较大小 class Pair[T](val first: T, val second: T) { def smaller = if (first.compareTo(second) < 0) first else second } 无法确定 first 是否存在 compareTo 方法，所以必须添加约束，fist 必须是 Comparable 的子类型，即需要添加上边界 class Pair[T <: Comparable[T]](val first: T, val second: T) { def smaller = if (first.compareTo(second) < 0) first else second } 下边界 T >: LowerBound //
