Given how much I use markdown everyday, I just can't live without it.

As I mention often, markdown is my goto format when I write docs.

This online tool converts from excell/openoffice and such to markdown.
It has some limitations (for example in number of columns or lines)

I restart local database (postgres in a docker container) and then my server bundle exec bin/rails s

After that I go to the console with bundle exec bin/rails c (or bin/rails c or bundle exec rails c),
being in the project root folder.

Sometimes (not sure exactly why yet), environment get messed up.
When trying a request such as : User.count I get a weird error.

could not connect to server: No such file or directory (ActiveRecord::ConnectionNotEstablished)
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

While the server is running locally and could connect to the database.

It happens the console explicitly starts with the following announcement :

Running via Spring preloader in process 1720240

Hey ! That's a good hint.
Of course, I did disregard it completly for a couple hours -- more than once.

The solution is so often related though. You reload the database and the server,
under spring preloader's feet.

spring prelaoder is so lost ! Let's restart it too.

Solution :

spring stop
bin/rails console

and voilà ! It works again.

Edit 2022-01-23 :

Beware, in the new console, if you do User and get this answer :

User (call 'User.connection' to establish a connection)

Solution is very simple : User.last and there you go. Connexion established, problem solved

Notez bien mes mots : TOTAL BULLSHIT.

Simple to use :

• Read csv using headers to name symbols
• Parse table like each row is a hash where each column header is a symbol's name.
• do whatever you want with value.

Example :

require 'smarter_csv'                                                               

# Class CodePostaux                                                                 
class CodePostaux                                                                   
  attr_accessor :csv_file_path, :cp_hash                                            

  def initialize(csv_file_path)                                                     
    @csv_file_path = csv_file_path                                                  
    @cp_hash = Hash.new                                                             
  end                                                                               

  def read_csv                                                                      
    SmarterCSV.process(@csv_file_path, {col_sep: ';'})                              
  end                                                                               
end

output = File.open('./test/minitest/fixtures/code_postaux_provisioning.rb', 'w')    
codes_postaux.each do |value|                                                       
  output.write("PostCode.create(code: '#{value[:code_postal]} #{value[:nom_commune]}')\n")    
end                                                                                 
output.close

hello https://www.bortzmeyer.org/ --

Now I have this one bookmarklet installed.
By the way, that means bookmarklets work again !

Not much to say, is 2.6.x compliant

It took me some time to understand that sugar syntax.
First of : it's & :to_s obviously.
Operator is &.

What does it do ?

it turns

mythings.map(& :upcase)
# is the same as 
mythings.map(&:upcase)

into

mythings.map { |mything| mything.upcase }

Remark : sugar syntax can be a pain in the butt. I hope you do see it.

The map method applies the "block" { |mything| mything.upcase } on each and every elements of mythings and returns an enumerable of class mythings.class containing each result.

The operator is & and the argument in my example is :upcase. :upcase is a Symbol.
Symbols have a smart to_proc method.

Another example :

require 'date'
[1,DateTime.now,3].map(&:to_s)
# => ["1", "2021-09-05T12:06:54+02:00", "3"]

So how does it work ?

• &̀ when a parameter of a method is prepended with & then ruby knows this parameter to be a Proc

• :upcase is a symbol.

So the &:myproc is a smart shortcut implemented to turn the symbol :myproc into a proc.

Let's try it :

def call_my_block ( my_parameter, &myblock)
  myblock.call.myblock
end

The parameter &myblock is known to be a block.

When I use method call_my_block with the argument &:my_symbol :

• The second parameter is known to be a block.
• The argument will be translated into :my_symbol.to_proc
  If the first argument is of class KlassandKlassactually has a my_symbol method, then it will call it.

Example :

call_my_block DateTime.now , &:to_s translates into :

:to_s.to_proc.call DateTime.now 

note that :

a = :to_s.to_proc
#=> #<Proc:0x000055e77c191c98(&:to_s)>
a.call(13)
#=> "13"
a.class
#=> Proc

Hence :

call_my_block DateTime.now , &:to_s
# => "2021-09-05T12:06:00+02:00" 
[1,DateTime.now,3].map { |val| call_my_block(val,&:to_s) }
#=> ["1", "2021-09-05T12:21:54+02:00", "3"]
[1,DateTime.now,3].map(&:to_s)
["1", "2021-09-05T12:23:22+02:00", "3"]

Note ::

• A function/methods has parameters.
• When called the function is given arguments

In other terms, an argument is the value of a parameter.
