Overview Given a grammar in (limited) EBNF, this online tool automatically calculates the first, follow, and predict sets. It also generates LL(1) parser tables from the predict sets, as done byFischer & LeBlanc. The sets are shown in two formats: human-friendly tables, and machine-friendly...
这意味着我们很可能不能借助parser generator。 至于原因:一般,运算符的复杂优先级关系会需要LR文法,但high level的语法结构往往只需要LL文法,前面提到,LL文法有一些好处,尤其对于错误信息的报告。一门语言的语法设计,会遵循类似歧义的层次,high level很难有歧义。因而开发者可以实现一个层次化的parser。这样,也会有一...

Eventually I was told that you import a pattern file into your application, but until the release ofModel/IO in iOS 9, you had to write your own parser from scratch to import a file from Blender or Maya. So I faced an incredible amount of frustration trying to figure out how you get...
A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. PaloAlto...
