ragel | Ragel State Machine Compiler | Machine Learning library

I want to speed up my program written in Go and convert regular expressions to finite state machines with ragel. I cannot figure out how to match end of input correctly when converting regular expressions similar to /cat[s]?(\b|$)/ (it matches a word border or end of input), so I made this workaround:

I m trying learn ragel with go, but i am not able to find a proper way to scan a Quoted-string

This is what i have defined

I ran a docker container with binding a host directory to a container directory, but the permissions for the container directory and its files are given differently depending on the hosts.

State machines, the terminology, and the tools are all new to me, though I've been trying to wrap my head around them lately with various online resources. This started when I wanted to build a faster parser than regex in Ragel and Go. I'm stumped on chapter 3 of the Ragel docs which covers actions.

It's not clear to me what the difference is between the actions tied to the state transitions vs the states themselves. The examples only have errors for the state embedded actions, so I'm not sure when you would use the to and from operators. I made a simple example:

I want to look at the results of code coverage in a script that then decides whether it is ok for the user to proceed. Does pants have this functionality? Is there any way to do this other than piping it into an external file and parsing?

Right now it prints everything to stdout, which isn't the best for what I'm trying to do. On top of that, when I do pipe to another file, I don't get the actual code coverage, just the compilation pants does up the it, like so

I'm getting a trouble while build my travis file. pop an error package errorX: unrecognized import path "errorX" (import path does not begin with hostname), and I can't tell which part causes it.

There is an example in Ragel manual 6.5 Semantic conditions, which demonstrates how to write a grammar for variable size structures, using when clause.

I have a very simple Python project and I'm trying to run tests using Travis CI.

Here's my .travis.yml

I'm using Ragel 6.10 with Go. I'm sure it's likely an issue with my code but I'm getting some weird errors when I try to use a stack with a scanner block. I'm trying to setup bracket matching and my code looks roughly like this;
