The main problem here is that the command mkdir is being called at a specific location, and it's just not there:

make: /usr/bin/mkdir: Command not found

To fix this, you need to add a symbolic link to that location:

$ sudo ln -s /bin/mkdir /usr/bin/mkdir

Run gem install again on rails and all should be good!

Thanks to user dem1tris from brining up a related topic, and providing the answer: make: /usr/bin/mkdir: Command not found during `gem install nokogiri` in Ubuntu 20.04

QUESTION

Parsing strings of user input using the cparse library from git

Asked 2019-Dec-17 at 13:37

I am new to c++ programming and wish to use the cparse library found here https://github.com/cparse/cparse in my project. I want to interpret strings of user input like "a*(b+3)" (for variables a and b) and use it as a function repeatedly on different sets of input.

For example, taking a text file as input with 2 double numbers per line my code will write a new file with the result of "a*(b+3)" on each line (assuming a is the first number and b is the second).

My problem arises when I try and include the cparse library from git. I followed the setup instructions naively (being new to git):

Failing that, is there another way to parse strings of user input and use them as functions?

I would like to answer this part of your question because I have the feeling that a full-featured C parser might be a little bit too heavy for what might be your intention. (Btw. once you got the C parser running – how to process its output? Dynamic linking?)

Instead, I want to show you how to build a simple calculator (with recursive descent parser) on your own. For the documentation of the techniques I will use, I warmly recommend Compilers (Principles, Techniques & Tools) by Aho, Lam, Sethi, Ullman (better known as "Dragon books") and especially Chapter 4.

The Tiny Calculator Project

In the following I describe my sample solution part by part.

Language Design

Before starting to write a compiler or interpreter, it's reasonable to define a language which shall be accepted. I want to use a very limited sub-set of C: expressions consisting of

C like floating point numbers (constants)
C like identifiers (variables)
unary operators + and -
binary operators +, -, *, and /
parentheses ()
semicolons ; (to mark the end of an expression, mandatory).

Whitespaces (including line-breaks) will be simply ignored but may be used to separate things as well as to improve human readability. C or C++ like comments (and a lot of other sugar) I didn't consider to keep the source code as minimal as possible. (For all that, I got nearly 500 lines.)

The specific example of the OP will fit into this language with an added semicolon:

When running Visual Studio Code for my Ruby on Rails development project, there is a 'ruby' process constantly running at almost 100% CPU making my fans spin like crazy. Looking at the Open Files and Ports of that process in the Activity Monitor, it looks like this is being caused by some process (node_modules.asar?) scanning through data directories (my_project/public/system/**):

This turned out to be caused by the Solargraph gem. According to this explanation of the author, the exclude settings of this gem in the .solargraph.yml file don't work very well. Instead one should use more specific include settings. In my case I was using - **/*.rb as a single include setting. I've now changed this to:

Looks like a bug in the source code. parse_numeric_port() is only defined if GETADDRINFO_EMU isn't defined, but the code uses parse_numeric_port() if GETADDRINFO_EMU is defined or not (note my comments added to the code):

QUESTION

Is it Pythonic to depend on ValueError when parsing a parameter string?

Asked 2017-Oct-21 at 01:26

My specific concerns are

When parsing a parameter, is it intuitive for a future maintainer to understand code that depends on throwing an error?
Is it expensive to be throwing exceptions as a matter of course for the default case? (seems like it might be according to https://stackoverflow.com/a/9859202/776940 )

Context

I have a parameter counter that determines the name of a counter to increment, and optionally can increment by a positive or negative integer separated from the counter name by an =. If no increment value is provided, the default magnitude of the increment is 1. The function is fed by breaking up a comma delimited list of counters and increments, so a valid input to the whole process can look like:
