@jens1o change the supported extensions file addition to:

{ icon: 'travis', extensions: ['travis.yml'], special: 'yml' },

[jens1o]

done, thanks for the heads up

What does the "special" do?

[robertohuertasm]

Let's say you have a file with a .js extension but you want it to have the flash icon (weird but you never know...) then using a special attribute you're saying: this is a js file but if it has the following structure (extension attribute) then assign the "icon attribute"

[robertohuertasm]

In the current case, we're saying, ok this is a yml file (special) but if it has the following form (travis.yml) don't assign .yml icon to it but instead use the travis icon.

[jens1o]

Ahhh, now it's clear. Could you add it to the CONTRIBUTION.md file?

I'll create a link to these thread in the Readme. ref #201

My plugin has updated (to version 1.8.3), but the icon does not apear for my file.

I think that, maybe, this line:
{ icon: 'travis', extensions: ['travis.yml'], special: 'yml' },
should be:
{ icon: 'travis', extensions: ['.travis.yml'], special: 'yml' },

Add a .travis.yml file to your repository to tell Travis CI what to build:

I have tried to create a 'travis.yml' file, to see if the icon apears correctly, but no success..

@jens1o I am doing something wrong ?

I have tried to create a 'travis.yml' file

Travis files start with a dot .travis.yml. For me it works:

Have you started VSCode with admin rights so vscode-icons can install itself?

[robertohuertasm]

@AlexandreSNeto It should be working even without the dot so definitely you're missing something.

Update:
special has been replaced with contribType.

_Example:_
{ icon: 'travis', extensions: ['.travis.yml'], special: 'yml' }
becomes
{ icon: 'travis', extensions: ['.travis.yml'], contribType: ctype.filename }

Advise:
When you make any change to the supportedExtensions.js or supportedFolders.js, after you run the build command, if you are overwriting the existing installation of this extension in vscode, make sure to copy also the icons.json file.
