FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package pacc

pacc – PHP yACC

Parser generator (currently generates recursive descent parser and canonical LR(1) parser) for PHP.

Big refactoring from Jakub Kulhan's original pacc.

Get ready

add the axmachado/pacc as a development requirement:

php composer.phar require axmachado/pacc

There is executable bin/pacc, that is installed by Composer as vendor/bin/pacc.

Then, you can run the "pacc" command from your project directory:

./vendor/bin/pacc -h

Write parsers

Files consumed by pacc are structured like this:

    grammar <<parser_name>>;

    option <<option_name>> = <<option_value>>;

    @<<code>> {
        <<php code>>
    }

    <<rules>>

Rules are compiled into PHP parser code, header and footer are left as they are.

pacc uses YACC/Bison syntax for rules. Each rule constist of its name, :, body, and ;. Name has to match regular expression [a-z][a-z_]*. Body consists of expressions separated by vertical bar – |. Each expression can have some attached PHP code. For example: 

    numerical_operation
        : number '+' number { $$ = $1 + $3; /* $1 is first number, $2 is plus sign, and $3 is second number */ }
        | number '-' number { $$ = $1 - $3; }
        ;

In PHP code, you can use special variables like $$, $1, $2, $3, etc. In $$ is saved result of expression. Through numerical variables you get result of subexpressions.

Look for inspiration in examples/ directory.
