clue / graph-composer Goto Github PK

I am getting an error that says:

In GraphViz.php line 206:

Unable to invoke "dot" to create image file (code 127)

graphp/graph#99

the requirement is one issue .. but the fact it gives no information if the command is not available is the bigger issue.

Add a self-update command to the graph-composer.phar.

Possibly related:

• fabpot/PHP-CS-Fixer
• composer/composer
• herrera-io/php-phar-update

I get this error:

Unable to invoke "dot" to create image file (code 127)

I have installed the graphviz, I have tried to reinstall it again, but I still get the same error.

Using Yii2, controller action:

public function actionGraph()
{
    $dir = Yii::getAlias('@app') . '/vendor';
    $graphComposer = new \Clue\GraphComposer\Graph\GraphComposer($dir);
    $graph = $graphComposer->createGraph();

    $graphviz = new \Graphp\GraphViz\GraphViz();
    $graphviz->setFormat('svg');
    $svg = $graphviz->createImageFile($graph);
    return $this->render('graph', ['svg' => $svg]);
}

and view:

<?php

/**
 * @var $this yii\web\View
 * @var $svg string
 */

var_dump($svg);
use yii\helpers\Html;

$this->title = 'Dependency Graph';
$this->params['breadcrumbs'][] = $this->title;

?>

<div class="site-dependency-graph">
    <h1><?= Html::encode($this->title) ?></h1><br />

    <div id="graph-placeholder">
        <!-- place here the svg file -->
        <?= $svg ?>
    </div>
</div>

Add an option to export the graph with links, similar to http://godoc.org/github.com/docker/docker/api/client?import-graph

Please update symfony console dependency:
"symfony/console": "^2.1|^3.0",

When installed over composer global require clue/graph-composer after trying to to run graph-composer it says:
ERROR: Composer not properly set up! Run "composer install" or see README.md for more details

Ran this to install:

composer require --dev clue/graph-composer

Tried this but there is no vendor/bin folder even:
./vendor/bin/graph-composer show

Tried this but get error message:
./vendor/clue/graph-composer/bin/graph-composer show

sh: dot: command not found

  [Fhaculty\Graph\Exception\UnexpectedValueException]
  Unable to invoke "dot" to create image file (code 127)

Need to update installation directions to require dot even if installing via composer.
Also fix or update installation directions for the vendor/bin problem.

Some projects have many dependencies and the graphs can get too large (#11). One option would be to add a --depth option in order to limit the depth of the resulting graph.

For example, the following could be used to display only direct dependencies (i.e. no sub-dependencies):

$ graph-composer show --depth=1

Special care may have to be taken with regards to loops/circles in the graph.

The current behavior is to also visualize development dependencies. This should be changed to ignore them by default and add a new --dev argument flag which enables showing development dependencies.

Error:
Composer not properly set up! Run "composer install" or see README.md for more details

The default exported image is from up to down. So, when the dependence packages go large, the width of the image goes wide.
I think it would be better to make it left to right (Or you can do an option), at least as a tree, the depth wouldn't go so far. It is more convenience to scroll from up to down than scroll left to right...
( :) a lot of directions may not confuse you )

Actually exporting to GraphML should be implemented in graphp/graph#3.

This ticket serves both as a valid use case for its implementation and as a reminder to add the necessary glue code to take advantage of it within this project.

Currently, generating a graph image just fails if GraphViz (dot executable) is not installed. Instead, we should check for the existence and fail gracefully with a concise, readable error message. On Debian-based systems, we could perhaps also offer to install it via sudo apt-get install graphviz.

Ex.:

graph-composer . --package clue/graph-composer

If current project has several dependencies

The following deprecation notices are generated when I run the latest release on PHP 8.1

Looks like composer build is not compatible with composer v2.

$ composer build

[1/1] Creating phar graph-composer-1.1.0-5-g25ea081.phar
  - Adding main package "clue/graph-composer"
  - Adding composer base files

Catchable fatal error: Argument 1 passed to Clue\PharComposer\Package\Package::__construct() must be of the type array, boolean given, called in /root/graph-composer/vendor/clue/phar-composer/src/Clue/PharComposer/Phar/PharComposer.php on line 136 and defined in /root/graph-composer/vendor/clue/phar-composer/src/Clue/PharComposer/Package/Package.php on line 21
Script @php build.php handling the build event returned with error code 255

Build still works fine however in composer v1 (now deprecated). I noticed this when attempting to containerize this (see https://github.com/patricknelson/graph-composer-docker).
Step to reproduce:

# Get graph-composer-docker repository and work from the 'composer-2' branch
git clone [email protected]:patricknelson/graph-composer-docker.git
cd graph-composer-docker
git checkout composer-2

# Tries to build container, but will fail
docker-compose up -d --build

Basically, what the Dockerfile does:

• Install composer 2
• Clone down https://github.com/clue/graph-composer.git
• Installs dev dependencies
• Runs composer build (and fails)

EDIT: You can see the diff in Dockerfile now in this PR: patricknelson/graph-composer-docker#1

My graph is just to large. I want to use it for documentation purposes and don't want to show up third party graph-nodes.
So a regular expression filter would help me here.

Would you merge this?

Best regards
Philipp

Use http://home.mircad.nl/md/Dot_image_map.html to optionally allow an image map to be exported with the same name as the image file to make the nodes in the image clickable. When clicked, the link should go to packagist.org/packages/org-name/package-name.

I just played around with your phar and created a graph of my project (phundament/app).

How could I stretch or expand the nodes so that the connections become more clearly visible?
Or adjust the layout so that the nodes are distributed more into a vertical direction.

wget https://github.com/clue/graph-composer/releases/download/v1.0.0/graph-composer.phar
php graph-composer.phar --version

Output:

graph-composer version @git_tag@

Expected:

graph-composer version 1.0.0

Hi,

Why I can read just "_root" in export.png ?

Thank you

@wol-soft has implemented an up-to-date check based on #45 in wol-soft#1 which colorizes the graph.

Colorized graphs work like:

• green: latest version
• lemon-green: patch available
• yellow: minor patch available
• orange: new major version available
• red: package is abandoned

Originally posted by @wol-soft in #45 (comment)

There seems to be a issue with packages with non lowercase package names.
Example:
http://hhvm.h4cc.de/graphs/laravel_4_1.png

The package jeremeamia/SuperClosure has two nodes, one in mixed case and the other in lowercase.

I created the following dockerfile to test this project

FROM alpine:3.13

RUN apk add --no-cache curl

WORKDIR /app

RUN curl -o graph-composer -L https://clue.engineering/graph-composer-latest.phar && chmod +x graph-composer

FROM php:8.0-cli-alpine

COPY --from=0 /app/graph-composer /usr/local/bin/graph-composer

RUN sed -i '/edge/s/^#//' /etc/apk/repositories \
    && apk add --no-cache graphviz

WORKDIR /app

ENTRYPOINT ["/usr/local/bin/graph-composer"]

Would you be interested in connecting it to your project in any way ? It can of course be modified.

The current steps to build and deploy a new graph-composer.phar are:

1. Install project and dependencies as per README.md
2. Install box.phar as per its readme
3. Run php box.phar build to generate a new graph-composer-{version}.phar
4. Upload the phar to any hosting service and get its URL
5. Update README.md to reflect new download URL

Obviously, this should be automated. Possible solutions:

• Perhaps using some external cloud service? I suppose we're not the first to run into this?
• Perhaps using something like bintray to host the phar archives (could automatic steps 4 and 5)
• Any suggestions?
