I'm working on a sniff for PHP_CodeSniffer 3.x. For example, the class declaration class NoInlineFullyQualifiedClassNameUnitTestInc extends \PSR2R\Base\AbstractBase should be split into a uses and class AbstractBase. The sniff detects similar issues for method signatures.
I believe the problem is that I'm generating and inserting multiple use statements at the same line (i.e., same token), but doing so in separate fixer->beginChangeset() ... fixer->endChangeset() sequences. The fixer treats multiple sets of changes to the same token as a conflict, and things get messy (and wrong).
The GitHub issue is here: https://github.com/php-fig-rectified/psr2r-sniffer/issues/9
Has anyone figured out how to do this writing custom sniffs for the latest 3.x CodeSniffer?
You can also use SlevomatCodingStandard\Sniffs\Namespaces\ReferenceUsedNamesOnlySniff
It turns this
Into this
How to use it?
The best is to use it with EasyCodingStandard like this:
# easy-coding-standard.neon
checkers:
- SlevomatCodingStandard\Sniffs\Namespaces\ReferenceUsedNamesOnlySniff
Install it:
composer require --dev symplify\easy-coding-standard
Run it:
vendor/bin/ecs check src
Fix it:
vendor/bin/ecs check src --fix
Enjoy and let me know how it works for you.
If any troubles come up, just create an issue here. I'm happy to improve this tool as much as possible.
The problem is multiple Sniffer (fixer) changesets editing the same token. I was able to get the Sniff to work by collecting a list of USE statements and inserting them at the end of the Sniff's processing.
I identified the end of processing by searching backwards from the last token to find the first token of the list of registered tokens.
Edit: Here is the sniff: https://github.com/php-fig-rectified/psr2r-sniffer/blob/master/PSR2R/Sniffs/Namespaces/NoInlineFullyQualifiedClassNameSniff.php

With symfony console commands you can prefix/group each one by putting in the setName("group:command"), and this is great.
myown
myown:cool
myown:foo
myown:bar
But the problem is that some external dependencies dont use this format. Ex: Phinx Migrations.
Since I'm importing an dependency that has a console command called migrate, I dont want for it to show without prefix/group. Not just because I might have another command called migrate or just for readability. I don't event know if we have 2 with same command name which one will show (need to check).
My question is: Is there any away for me to force a group commands from an external depencency to be inside an prefix/group?
You can achieve that, I wouldn't recommend but that would be the approach:
Create a compiler Pass which removes the definitions of the Commands you don't like
Register again all those commands while setting the names you like
If you need information on compiler passes:
https://symfony.com/doc/current/components/dependency_injection/compilation.html#components-di-compiler-pass
Maybe there's an easier way which I'm not aware, but for now that's my answer to you, I can't post all the code because that would be a lot of code and if you do it maybe you can update with the solution.
Good luck
I am trying to make changes to the behavior of a function and print the results to a file. The ViewCfg plug-in described in the Plug-in Development Guide does something similar, but I am trying to avoid having to use Ast.get, which ViewCfg uses. I am thinking of extending Printer.extensible_printer which, according to the Frama-C API Documentation, is something I can do if I want to obtain a custom pretty-printer.
However, if I extend the pretty-printer as described in the API docs, unless I'm doing something wrong, I notice that the changes I make take place regardless of which project is set as the current project. I'm using File.create_project_from_visitor to create a new project and Project.set_current to set the new project as the current project before I use the custom pretty-printer.
Is it true that any change made by a class that extends Printer.extensible_printer applies to all projects? I happen to be using frama-c-Aluminium-20160502, which I know is not the latest version.
EDIT: Sorry, I should have made this clearer in the beginning, but I'm not actually making changes to the behavior of a function. I'm reading in the behavior of a function, then based on that, I'm trying to generate as output valid C code that's meant to be read as input by another program.
Regarding AST.get, the only reason I was avoiding it was that it sounds like it gets the entire AST, while I'm only interested in part of it, i.e. behaviors. But if I'm just making things harder for myself by avoiding it, then I'll go ahead and use it.
first of all, i will explain what i would like to do here : given a C big programm, i would like to output a list of producers/consumers for a data and a list of calling/called-by functions of the function where this data is.
for doing this, i am thinking about using what computes some modules of frama-c, like dataflow.ml or callgraph.ml in my own plugin.
however, as i read the plugin developper doc, i can't manage to see how we can have access to the data of those modules.
is a "open.cyl_type" sufficient here in my own plugin?
moreover, here are my other questions :
i tried using by the way pdg plugin for my purposes but when i call it and it says "pdg graph computed", how can i access it?
is there any more documented thing about "impact" plugin than the official webpage, in depth, how it works fondamentally? (i have to say that i'm in like a pre-project phase, and that i installed frama-c with the apt-get on ubuntu and that i did not get an impact plugin working (i'll see by compiling the sources))
by the way, do you think i'm using the right method to get to my purposes?
Your question is quite unclear, and this answer is thus very generic. As mentioned in the developer documentation, there are two main classes of plugins: static plugins, compiled with the kernel and whose API is exposed in a module (usually of the same name of the plugin) in Db. Dynamic plugins, such as Semantic_callgraph register dynamically their entry points through the Dynamic module.
If you do make doc in Frama-C sources (I'm not sure that there is a corresponding package in Ubuntu) you can access documentation for the Db module in FRAMAC_SOURCE_DIR/doc/code/html/Db.html and the list of functions registered by dynamic plugins in FRAMAC_SOURCE_DIR/doc/code/dynamic_plugins/Dynamic_plugins.html.
I think that, following Virgile's advice, you should get the source code anyway because you will most of the time need to browse the code to find what you are looking for. Beside, you can have a look at the hello_word plug-in (in src/dummy/hello_world) to have an example of a very simple plug-in. You can also find some examples on my web site at https://anne.pacalet.fr/Notes/doku.php?id=notes:0061_frama_c_scripts to find out how to have access to some information in the AST.
when i create an article useing the story type,could i add some variables into the body's textarea.then can invoke the variable and output it. thank you.
the drupal version is 6.
Inserting textual placeholders to be replaced by actual values on render is the purpose of the filters system in Drupal. Token filter provides, well, token replacement and is an handy tools if your need replacement for tokenized values. But there are plenty of filters for Drupal 6.x and you can even define your own in a custom module. The Custom filter can help for this. You can also use token filter and define your own token in your custom module.
A simple solution is to use the PHP filter but this is a insecure way of doing it. Also, putting PHP code in node (or any content) is a maintenance nightmare and a bad habits. You would be better doing it properly from the start.
Contrib modules would be the way to go, unless you feel comfortable with PHP in which case you can just use the PHP filter. Depending on what variables you need you can try one of:
http://drupal.org/project/InsertNode and http://drupal.org/project/token_filter
There are a couple of others (I like insert view) but they're currently not marked for production use.
I have seen several projects that use the Trace functionality to capture events and stream them out to a log file. I have been unsuccessful in finding a simple to follow guide that will show me how to configure Trace to capture and write said logfile. Does anyone have a link recommendations, or provide some simple steps to follow?
The Trace object writes the statements to any attached TraceListeners. You can build your own, but there are a number already defined in the System.Diagnostics namespace, including:
ConsoleTraceListener (Console)
DefaultTraceListener (Visual Studio / Debugger)
DelimitedListTraceListener (TextWriter, special formatting)
EventLogTraceListener (EventLog - anything that inherits from System.Diagnostics.EventLog)
TextWriterTraceListener (TextWriter - think file)
You can, of course, inherit your own from the TraceListener class that writes to where ever you want. For example, you could log to a database, have it send e-mails or pages in certain situations, or write the statements back to a logging platform like log4net.
The big thing is that you need to create an instance of whatever listeners you want and then add them to the Trace' class Listeners collection. You can add as many as you need and Trace will write to all of them. This way, you can write your logging code once using a well-supported and understood object that's part of the framework, and you can attach anything you need to it.
I stumbled into a MSDN article that really helps. Sorry I didn't find it before posting the question but perhaps others may have the same question and haven't found this link.
Take a look at logging frameworks. We rolled out own, but are now migrating over to log4net available free at http://logging.apache.org/log4net/
Im looking for a way to set the Category of the EventLog, the FormattedEventLogTraceListener writes into (not the category of the message).
But I can't find an appropriate property of this class.
Is it possible to set this?
