LGTM overall. Just some minor changes and more test coverage needed (see codecov)

+    public function format(string $content, string $uri)
+    {
+        // remove 'file://' prefix
+        $uri = substr($uri, 7);


I don't think this is the right way to do it - an input of file:///c:/users/felix/test would result in /c:/users/felix/test which is not a valid path. #31 adds a path2uri function, I would propose to add the reverse uri2path function (with some tests) https://github.com/MadHed/php-language-server/blob/7b0b9b890cabd3f0c2e1d7f10314ed61f53df110/src/utils.php#L23-L33

For now I added new method to Formatter to avoid conflicts with #31. Later I can move it to utils.php

I noticed that a big mess happens when formatting (in VSCode) the SymbolFinder.php file - in this part: https://github.com/felixfbecker/php-language-server/blob/master/src/SymbolFinder.php#L54-L63

mniewrzal · 2016-09-29T21:36:52Z

Code Sniffer is failing to format SymbolFinder.php. I added simple error handling. Tomorrow I will report this problem to PHPCS.

Will merge #31 first, will probably be some refactoring for you to rebase

mniewrzal · 2016-09-30T09:17:52Z

Ok, I'm aware of that ;)

Non-optional parameter cannot follow an optional param. Both should be optional to allow constructing a instance and then setting the properties manually

Not a valid URI, space needs to be %20

+        $uri = "c:\\home\\foo\\bar\\Test.php";


That's not a valid URI so I don't think we need to test against it

+    }
+    $path = substr($uri, $position + 3);
+    return strpos($path, ':') ? str_replace('/', "\\", substr($path, 1)) : $path;


Not that happy with this implementation.

If possible I would like to use parse_url

Needs to handle %-encoding

Needs to replace / with DIRECTORY_SEPERATOR

+        $this->assertEquals([], json_decode(json_encode($result), true));


Imo an invalid URI should throw an error instead

Actual implementation will create PhpDocument for invalid/non-existing uri (Project::getDocument). I can try to reorganize this with this change but I think it should be done as separate issue.

Fair enough.

src/Formatter.php

+        do {
+            $default = $currentDir . DIRECTORY_SEPARATOR . 'phpcs.xml';
+            if (is_file($default) === true) {
+                return array($default);


Use short array syntax

felixfbecker

Tests for uriToPath and pathToUri should be symmetric, could you clean them up a bit?

felixfbecker · 2016-10-04T10:56:34Z

src/utils.php

-    $path = substr($uri, $position + 3);
-    return strpos($path, ':') ? str_replace('/', "\\", substr($path, 1)) : $path;
+    $path = urldecode(parse_url($uri)['path']);
+    return strpos($path, ':') ? str_replace(\DIRECTORY_SEPARATOR, '\\', substr($path, 1)) : $path;


strpos may return 0 or false, should check explicitly for false here

It's str_replace($search, $replace, $subject), we need to search for '/' and replace it with DIRECTORY_SEPERATOR

Should be ok right now.

+        
+        $uri = 'file:///c%3A/foo/bar.baz';


The colon after the drive letter is typically not encoded afaik
https://en.wikipedia.org/wiki/File_URI_scheme#Windows_2

Changed to simple colon.

Eclipse Che requires an accurate calculation of the end position. Although VSCode can handle this well, the editor in Che just breaks if any negative values or big values beyond the document end are provided.

Ok, I will try to calculate end position.

Thanks! This now works very well in Che.

@felixfbecker is there anything else pending (except resolving conflicts) for this PR to be merged?

felixfbecker

There a few minor nitpicks which I will just fix myself if you don't beat me to it. The important stuff really is support for non-file URIs

felixfbecker · 2016-10-10T07:16:12Z

src/Formatter.php

+    {
+        $path = uriToPath($uri);
+        $cs = new \PHP_CodeSniffer();
+        $cs->initStandard($this->findConfiguration($path));


Will this also work in environments where

URIs are not file URIs

there is no config file in the project
?

Will this also work in environments where

URIs are not file URIs

For directory URI it wont work if URI = directory with config file but in this case it will load default configuration. Should we be worried about such cases? Do you notices URIs different than file?

there is no config file in the project ?

If config file is not found PSR2 standard is loaded.

What I meant was that we need to handle URIs that don't use the file:// scheme, but something like vfs://.

Ok, understand now. We can think about it later.

felixfbecker · 2016-10-10T07:20:27Z

src/utils.php

+ */
+function uriToPath(string $uri)
+{
+    $filepath = urldecode(parse_url($uri)['path']);


A URI can have any protocol, but only file URIs can be mapped to a path. We need to throw an InvalidArgumentException if the URI is not a file:// URI and also handle/test that case in the implementation.

felixfbecker · 2016-10-10T07:23:37Z

src/utils.php

+function uriToPath(string $uri)
+{
+    $filepath = urldecode(parse_url($uri)['path']);
+    return strpos($filepath, ':') === false ? $filepath : str_replace('/', '\\', $filepath);


This is a little brittle. There are also implementations that use | instead of the colon on windows. You don't need to test against that, but it would be better to simply do str_replace('/', DIRECTORY_SEPERATOR, $filepath)

https://en.wikipedia.org/wiki/File_URI_scheme#Windows

Forget what I said. the directory separator should of course be determined by the URI, not the runtime OS.

felixfbecker · 2016-10-10T07:26:01Z

src/Formatter.php

+    private function calculateEndPosition(string $content): Position
+    {
+        $lines = explode("\n", $content);
+        return new Position(sizeof($lines) - 1, strlen(end($lines)));


Please use count, sizeof is just an alias and PHP has so many aliases nobody can remember them all 😄

felixfbecker · 2016-10-10T07:26:58Z

src/Formatter.php

+     * @param string $uri            
+     * @return string[]
+     */
+    private function findConfiguration(string $uri)


The parameter is named $uri, but you call it with a path, not a URI. Some description for the function and params would also be nice

tests/FormatterTest.php

+        $this->assertTrue($edits == []);

Missing newline - I don't know which editor you use but I recommend you to look for an EditorConfig extension 😉

src/Formatter.php

+use LanguageServer\Protocol\{TextEdit, Range, Position, ErrorCode};
+use AdvancedJsonRpc\ResponseError;
+
+class Formatter


Initially I was wondering why this needs to be a class that is instantiated when it has no properties, constructor or internal state. Everything could just be pure functions. But it's probably better to encapsulate the private functions. One possibility would be though to make them static and the class abstract. Opinions on this?

I added this class to prevent messing with PhpDocument in future. Abstract class and static methods sounds ok for me.

Fair enough.

+        $this->assertEquals([], json_decode(json_encode($result), true));


Don't need to json_decode(json_encode())

+    public function format(string $content, string $uri)
+    {
+        $path = uriToPath($uri);

Please add a use PHP_CodeSniffer at the top. This declares the dependency on the class and avoids having to use absolute references
