    Phan uses the language server protocol, so it should work with language server clients, although I haven't tested the language client for phpstorm

    https://github.com/phan/phan/wiki/Editor-Support has an example of a command you'd use for "Sublime Text 3", and I'd suggest replacing the psalm command and arguments with the phan command and arguments for the instruction in https://psalm.dev/docs/running_psalm/language_server/#phpstorm

    I haven't tried phpstorm, though

    @TysonAndre Thanks, I gave it a try and got the following exception;

    What version of reflection-docblock is this
    What version of php is this, I'd have thought phan required 7.1+ to even run the language server, so I'm not sure how the object exception happened
    oh, you're probably using reflection-docblock 5.0.0 and php 7.1
    Downgrading to phpdocumentor/reflection-docblock=^4.3.4.0 should fix that
    I'm guessing composer install|upgrade ran with php 7.2+ and your language server ran with 7.1 locally
    Tyson Andre
    @TysonAndre
    Or install phan in a different directory, or use the phan.phar releases
    NicklasWallgren
    @NicklasWallgren

    Oh, I might have configured something wrong .

    Right, the path to the php binary was wrong and pointed to php 7.1, sorry. So I got the intellij-lsp plugin working with the language server, the errors are displayed but the plugin seems pretty limited. I'll keep using the cli command instead.

    The errors are for example duplicated
    Tyson Andre
    @TysonAndre
    It could be related to symlinks if you're using those. The language server deliberately limits errors to the open files. I'm not familiar with the phpstorm client.
    Tyson Andre
    @TysonAndre

    It could be issues with case insensitive filesystems or normalizing ./ (e.g. both src and SRC)

    Possibly related to gtache/intellij-lsp#91 after a quick search for "diagnostics", could also be related to the way Phan's diagnostics are spread from column 0 of one line to column 0 of the next line.

    Tyson Andre
    @TysonAndre
    phan/phan#3826 improves the error message for reflection-docblock requiring php 7.2+ when run in php 7.1.

    Greetings, I thought I'd come in here to seek some help. I've been trying to get Phan for VS-Code to work for the past 2 Hours, and for some reason it does not seem to work for me. Current steps I've taken: PHP7.2 is installed, got myself AST, disabled all other plugins for vscode, added the analyzed Path in VS-Code. Verified that vs-code can find php by running "php -v". enabled logs for phan. Those tell me that the lang server has started and is accepting connection on localhost:someport (It does also show in vs-codes process explorer). I do have a .phan/config.php file in my project root. Which phan does seem to be able to find, the didChangeWatchedFiles hook does fire on file changes of the config. I have even tried to generate the config with phan --init, because I thought the config might be off. But I am not getting anything. No Error detection, no problems in the problems tab, nothing. If I run my own copy of phan.phar somewhere, it does work and prints a list of errors. I am at a loss here. If you need further info or this is not the place to ask this, please reach out, because I am at a loss. Versions are: Win10 - VS Code 10.43.2 - Analyzer Plugin v 1.2.3

    You could check the console output in Help > "Toggle Developer Tools" (Ctrl+Shift+I). (if you could post a screenshot, that would help)

    I'm assuming you're seeing the path to php 7.2 in vs code's process explorer, but it's worth checking if it's a different installation (e.g. older php, missing php-ast)

    You could also try installing an older version of Phan (Ctrl+Shift+X), click on the settings(gear) icon for phan, then "Install Another Version", e.g. 1.2.2 (vscode-php-phan 1.2.3 started adding a check that the files were actually within the project root directory, so it may be an issue with that. Let me know if that works or doesn't work.)

    Also, do you see any errors in daemon mode, and do expected diagnostics get emitted (e.g. phan --daemonize-tcp-port default in one window within the analyzed project directory, phan_client -l src/some_analyzed_file.php in another

    If 1.2.2 works, you could try setting phan.useRelativePatterns to false in 1.2.3

    There's a remote possibility it's an issue with case sensitivity (Phan expects the case of folder names to match for events sent by the language client) - probably not symlinks. Enabling phan.enableDebugLog would tell you more in developer tools

    Tyson Andre
    @TysonAndre

    no problems in the problems tab

    Also, the vscode plugin limits the problems to the currently open files so that responses are fast. If you don't see problems as you're editing files, though, that is a bug.

    Kevin Gregull
    @KevinGregull
    1.2.2 does indeed work for me
    as does disabling relative Patterns

    Hi guys. Anyone successfully made phan work with sublime text 3?
    I followed the tutorial here: https://github.com/phan/phan/wiki/Editor-Support
    image.png
    but had an error. here's a screenshot
    Tyson Andre
    @TysonAndre
    That's probably a different error from what the https://github.com/sublimelsp/LSP extension encountered. That's what I'd expect to happen if you ran the same command directly in a terminal and then manually sent the running program invalid input (a single blank line)
    https://lsp.readthedocs.io/en/latest/#server-configuration mentions you can configure LSP to log stderr/payloads - I've never used sublime text, though. The instructions were submitted by a user of Phan.

    what version does phan start supporting php 7.4? we're on 2.7.1 and it's showing us PhanSyntaxError syntax error, unexpected '?', expecting function (T_FUNCTION) or const (T_CONST) for a nullable property declaration.
    upgrading to 3 is next, but I didn't expect 2.7 to fail ...?
    Tyson Andre
    @TysonAndre
    You either need to run phan with --allow-polyfill-parser or run Phan with php 7.4+. Phan uses the php-ast PECL, which uses php's native AST
    The polyfill isn't perfectly compatible with the native AST support, due to limitations of tolerant-php-parser and a slight difference in doc comment parsing

    Hey guys, just thought I'd let you know the wiki page for the "Issue types caught by Phan" is not loading anymore. Not sure if it's transient or not. I can file an issue if you'd like. I know it was loading last week.
    Tyson Andre
    @TysonAndre
    It loaded now - similar issues were reported on other large files on unrelated projects

    @acepace
    is there any way to get from phan the derived type information to a file?
    Tyson Andre
    @TysonAndre
    There's nothing that does exactly that. There's phan's tool/dump_markdown_preview, which isn't the same thing as type information and isn't structured. There's --dump-signature-file <filename>, but that only dumps method signatures
    It's possible to do that through plugins or a script that starts phan's phases manually
    Ace Pace
    @acepace
    yeah, I looked at that and played around.
    Ace Pace
    @acepace
    @TysonAndre the signature file was actually great for me, I can generate a full structure graph of a project in a few lines from that
    next question is if you have an idea how do I dump the callgraph?
    Ace Pace
    @acepace
    image.png
    just to show what i'm pushing towards
    Tyson Andre
    @TysonAndre
    You'd have to write a plugin for it (AnalyzeFunctionCallCapability would help). tool/pdep is somewhat related, but not what you wanted - it dumps a graph of the dependencies of classes on other classes. Dumping method/property relationships might be within the scope of what pdep could eventually do, but I'm not the owner of pdep
    Tyson Andre
    @TysonAndre
    A more efficient approach would be enable the reference tracking setting or dead code detection and to use the references to classes to build the graph. That would get you everything except internal elements such as strlen, etc
        /**
         * @override
         */
        public function addReference(FileRef $file_ref): void
        {
            if (Config::get_track_references()) {
                // Currently, we don't need to track references to PHP-internal methods/functions/constants
                // such as PHP_VERSION, strlen(), Closure::bind(), etc.
                // This may change in the future.
                if ($this->isPHPInternal()) {
                    return;
                }
                if ($file_ref instanceof Context && $file_ref->isInFunctionLikeScope() && $file_ref->getFunctionLikeFQSEN() === $this->fqsen) {
                    // Don't track functions calling themselves
                    return;
                }
                $this->reference_list[$file_ref->__toString()] = $file_ref;
            }
        }
    Tyson Andre
    @TysonAndre

    I asked about pdep, but I doubt it's going to get implemented any time soon.

    Also, it wouldn't track calls to functions from themselves, etc., because this is focused on dead code detection
