Expected Behavior

No error or if PHP files with a .html extension isn't supported, maybe a notification/error/warning in the outline view that mentions this?

Actual Behavior

You get the error mentioned above and the outline view is blank.

Possible Fix

Not sure! 🤔

Steps to Reproduce

Save a file called test.html with this content:

<?php
function foo() {
  echo "<p>Hello World!</p>";
}
?>

<html>
 <head>
  <title>Hello World</title>
 </head>
 <body>a
<?
  foo();
?>
 </body>
</html>

Toggle the outline view with Outline View: Toggle

Context

The person that reported the error to ide-php thought the error was coming from ide-php but it was coming from ide-html - it was confusing for us because we assumed the error was with ide-php as well but we couldn't reproduce.

trying to find the root cause of this...

NOTE: whenever we have question mark ? in the tag it generates error

the following file has no error until adding a ? in some tag

<html>
 <head>
  <title>Hello World</title>
 </head>
 <body>a
- <
+ <?
  foo();
 >
 </body>
</html>

@liuderchi Looking at the payload that comes back it seems to be because the language server is returning an object for the final part (the <? inside the body) that does not have a name.

According to the language server protocol at https://microsoft.github.io/language-server-protocol/specification the name is not optional and should always be returned.

We could put code in to try and deal with this inside atom-languageclient although the best solution is having the language server itself fixed.

Damien Guard · Answer 3 · Tue Feb 27 2018 05:28:54 GMT+0800 (China Standard Time)

Next version of atom-languageclient will filter out any document symbols that have a name missing atom/atom-languageclient@aac3505

... try and deal with this inside atom-languageclient although the best solution is having language server itself fixed.

@damieng huge thanks for this workaround! 💯
Will upgrade atom-languageclient when this feature is released (probably v0.9.0)

Damien Guard · Answer 5 · Wed Feb 28 2018 07:20:53 GMT+0800 (China Standard Time)

v0.9.0 is now out with much better autocomplete too

Damien Guard · Answer 6 · Wed Feb 28 2018 08:08:22 GMT+0800 (China Standard Time)

Actually use v0.9.1 - 0.9.0 has a weird autocomplete bug.

@damieng @rsese ide-html has just released v0.4.2 (along with latest atom-languageclient).

Please upgrade ide-html to confirm that it solves this issue.
