access taxonomy fields programatically in drupal 8

Access one term:    

    $term = \Drupal::entityTypeManager()->getStorage('taxonomy_term')->load(TID);
    $value = $term->FIELD_MACHINENAME->value;

Example : load title and language of term id =2

    $term = \Drupal::entityTypeManager()->getStorage('taxonomy_term')->load(2);
    $title = $term->name->value;
    langcode = $term->langcode->value;

And for load Multiple

  $terms = $entityManager->getStorage('taxonomy_term')->loadMultiple($t‌​erms);
  foreach ($terms as $term) {
      var_dump($term->tid->value); //return tid of term
   var_dump($term->name->value); //return title of term
  }

Migration path info for drupal 8

if the path of your csv file is in the root of your project then:

source:

  plugin: CSV

  path: your_file.csv

the best practice is to put the csv file into your migrate module in a directory "artifacts" for example the structure should be as below:

-- custom_migrate_module

   +-- artifacts

         +-- your_file.csv

   +-- config

   +-- src

   +-- custom_migrate_module.info.yml

in this case your migration confg file should be:

source:

  plugin: CSV

  path: modules/custom/custom_migrate_module/artifacts/your_file.csv

Useful Drupal 8 modules

1. Conditional Fields - Allows for easy creation of conditional fields for content types.

find unprintable characters in vim

Using range in a [] character class in your search, you ought to be able to exclude the ASCII hexadecimal character range, therefore highlighting (assuming you have hlsearch enabled) all other characters lying outside the ASCII range:

/[^\x00-\x7F]
This will do a negative match (via [^]) for characters between ASCII 0x00 and ASCII 0x7F (0-127), and appears to work in my simple test. For extended ASCII, of course, extend the range up to \xFF instead of \x7F using /[^\x00-\xFF].

You may also express it in decimal via \d:

/[^\d0-\d127]
If you need something more specific, like exclusion of non-printable characters, you will need to add those ranges into the character class [].

Search through Git logs!

Taken from: https://www.gun.io/blog/git-search-log

So, you want to search your git commit logs. Good news! It's really easy, and I'm going to show you how to do it.

If you use git, you're probably already familiar with the classic UNIX string searching tool, 'grep.' (If you already know about grep but want something better, you should try out Ack, but that's an unrelated issue.)

Lucky for you, git has a 'grep' mode!

Suppose I wanted to search for the string "facebook" in all of the commit messages of my project. All it takes is this one command:

git log --grep="facebook"

and you'll see all of the log messages which contain the our search term!

Okay, now suppose that you want to search more than just the commit messages, but the commits themselves. Simple! Drop the 'log' argument.

git grep "facebook" $(git rev-list --all)

This will show the commit ID and line number of all instances of your string. (The string can also be a regular expression, which is handy if you know regex, too.)

This can be made slightly more human-friendly by using the 'pickaxe' feature of git log grep, like this:

git log -S"facebook"

which will show all the commit messages of commits which include your string.

Hope this helped!

Repair GIT Permissions

Repair Permissions

After you have identified and fixed the underlying cause (see below), you'll want to repair the permissions:

cd /path/to/repo.git
sudo chgrp -R groupname .
sudo chmod -R g+rwX .
find . -type d -exec chmod g+s '{}' +

Note if you want everyone to be able to modify the repository, you don't need the chgrp and you will want to change the chmod to sudo chmod -R a+rwX .

Good way to do git revert

UPDATE: This probably isn't as good:

I have found that doing

git revert --no-commit HEAD~(number of commits back)..

for example:

git revert --no-commit HEAD~3..

and then committing the changes is a great way to revert back to a previous commit without messing up git structure.

UPDATE: This is better:

git reset --hard (hash number) deletes all changes and goes straight to that commit.

git revert (hash number) allows you to merge changes made in that revision with the HEAD

Drupal 8 - Make sure to use if statements in hooks

When using a hook in drupal, be sure to use an if statement to assure that what you want to work with is present. The hook applies to everything on the site, and may cause issues if you are not thinking about that.
