The biggest problem of this extension is after the trial period. After I uninstall this extension, ALL editors stopped working. When I tried to open a javascript, css or even plain text file I got an error message from the editor.

codemix3 cant use with spring tool suite4 together, i use eclipse 2020.03 and spring tool suite4 4.7.0 codemix3 2020.03 ,after i install both of them , eclipse cant open anymore

I am looking for a way to decorate my console output to get clickable links back into my source files, or my data files, by making the text displays active.  I would like to color-code the text with red for errors, black for normal, and blue and green for other purposes.  This only needs to be active in the console window.  Could I use your product for this purpose?

Too bad the "CodeMix Engine Helper" consumes all the CPU of my Mac after a few minutes of use. It is therefore necessary to restart eclipse several times a day.
I am in a trial period of CodeMix, and today I am uninstalling it permanently, because it is wasting my time.
On paper it looks good, in reality it is full of bugs! I will not pay for this!

In reply to by Pierre Roger

Apologies for the delayed response - even though you posted nearly two weeks ago, the moderation here let your post through only a day ago :( There aren't any outstanding performance issues with CodeMix right now. Having said that, there are many reasons why this could happen, ranging from a misbehaving extension or a problematic project setup, to an actual bug in CodeMix. We're sorry to see you go, but if you do use CodeMix again and run into performance issues, please hit us up on Live Chat from within the product so we can diagnose the problem live, and figure out where things are going south.

Won't review the function of this as I installed it and didn't actually use it. 

The reason I'm reviewing is that after my trial (that I didn't know I had) expired, every editor window I had open was replaces with a dialog box asking for me to buy a subscription and closing the dialog delete the unsaved work I had in each editor window. 

Hijacking an editor window to get you to buy your plugin and deleting their work in the process isn't going to get anyone to buy your plugin. 

In reply to by Alex B

Alexander, first, let me apologize for experience you had, and the lost work - it is certainly not our intention to hold your code to ransom, even if you don't want to sign up. However, I'd like to clarify that CodeMix does not hijack all editors, we display the license dialog you encountered in CodeMix editors only. You said you didn't use CodeMix, but you were using CodeMix editors, apparently unaware of this fact.

When CodeMix is installed, we change the defaults editor for several file types (like HTML, JS, TS, etc.) to CodeMix, because that is the functionality this plugin provides. You seem to have run into an edge case where the license expired as you were using CodeMix, and the dialog appeared in several dirty editors, preventing you from saving them. This is a bug, one which we can track down and fix. Apologies once again, and thank you for the report.

This plugin has the gall to ask for money after closing the files I've been working on for the past couple hours without giving me a chance to save them. The service it provided was ok at best, but you couldn't pay me to use it again.

In reply to by D V

Sorry to hear you had that experience with CodeMix - definitely not our intention for you to lose work, under any circumstances. This appears to have been an edge case around license expiration that we have yet to reproduce, but our engineering and QA teams are on it. If you'd like to continue with your CodeMix trial, please write to - thank you for reporting the problem.    

I needed a jsx editor and gave it a try for several days.


  1. There are some really nice features.
  2. Many formatting, content assist, indent etc features cannot be properly configured and need intervention by support and editing of a settings.json file
  3. Support is friendly, quick and helpful.
  4. There are some very clear show stoppers. "save as" is broken and the interaction of the editor with eclipse project explorer is broken to an extent that you might unexpectedly lose large code fragments when saving. Not what you expect from a commercial code editor.

While the idea is cool (mixed language editing) this thins seems far from being a mature product. Grab your files and run.

You might want to check their forums to see that the "product" still is struggling with some rather elementary issues.

In reply to by Clemens Cap

Clemens – first, thank you for your candid feedback - we’re glad you like our feature set, and support. Our next release will expose the trigger completion setting (unfortunately missed in the UI), and we’re also looking at creating a single, “turn off all auto suggestions” switch, based on your experience.

Code OSS and extensions tend to make a very large number of settings available, while we strive to expose just the right level of settings so that we don’t overwhelm users. Users can go directly to the JSON file for more advanced settings.

 As we explained on the forum post, the Save As break was a recent regression that came in with other optimizations, and was somehow missed in our regression tests. We’re also adding move protection – and agree that both these areas should be rock solid. 

I’ll add a note here when the next release is available with the fix. Again, thank you for your feedback.

I downloaded Codemix3 plugin on eclipse Jee. When I make new HTML file the template is defferent from the one I have set on Eclipse. How can I make it match to the original set one or how can I edit the template that shows on Codemix3? Thanks!

I installed codemix pack but one message, again and again, show some notifications. that message is " please install codemix node pack". but I don't know how to install that package. anyone help me.

Really liked the features, but ultimately had to uninstall from Eclipse 2018-12.  There were 2 major problems:

  • Startup time dramatically increased and overall performance was very sluggish.
  • I was no longer able to do my current project build within Eclipse. Something was locking a project folder and causing a Node permissions failure.  This would also occur from a system terminal whenever Eclipse was running.  With Eclipse closed or CodeMix uninstalled the problem was resolved.

May give this another try sometime in the future.

In reply to by VML Johnson

Thanks for the comments. With an update release imminent, we hope you'll give CodeMix another try soon. There are many fixes and performance improvements in the release which could go a long way to addressing your concerns. If you try again and encounter issues, please raise them on our support forums at or, better still, use the built-in live chat facility, where our developers can give you real time assistance. Select Help>CodeMix>Live Chat to start a dialog.

After it expires if you don't want it, you have to uninstall. I uninstalled and Eclipse crashes on start,.. java.lang.IllegalStateException: Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini).

Very annoying!.. When it expires you can't open your files any more. No button to re-set the file associations back and uninstall breaks everything.

In reply to by Cristian Chiritoiu

Cristian, we're sorry your Eclipse installation was corrupted after uninstalling CodeMix, and can understand how frustrating that must have been. In rare cases, uninstalls (which are handled by core Eclipse) do not run through to completion due to a variety of reasons, and if bits of CodeMix are left behind, it would result in a broken state, as you have experienced. I will add that uninstallation of our software is part of our test matrix - it is regularly and rigorously tested, and we do not have a general failure in this area.

I realize this note comes too late for you, but when your license expires, while we disable the CodeMix editors, instead of uninstalling CodeMix, you can simply disable it instead, on the Preferences > CodeMix page. On restart, the IDE will go back to using your non-CodeMix editors.

I am in an environment where I need to use eclipse instead of intelliJ and I want to use codeMix to reduce the difference, but codeMix does not support egoveFramework I wonder if there is a way to force it

In reply to by 태민 김

I'm not familiar with the eGov Framework. Perhaps you could try searching for Visual Studio Code extensions that might support it. If you could provide more information about the framework, to our support site, we might be able to give you more assistance. Our forums are at

Thanks for using CodeMix. We're keen to look at any improvements that users would like.

Just installed, disabled for too much CPU overload, prompted to restart Eclipse: BOOM! Eclipse broken, empty window, no menus, no tabs, no way to solve from within the application!! If you have a solution please answer!

In reply to by Alessandro Domanico

I'm sorry you're seeing this problem Alessandro.

First off, this isn't the best place to raise problems, as it can sometimes take a few days for comments to appear. It's best to use the support page at the link above.

Please try starting with a new workspace and see if that fixes the immediate problem. If you can try the plug-in again, we can handle the issue on our support forums. If you go that route, please supply as much information as possible and attach the workspace error log.

Thanks for trying CodeMix and I hope you give it another shot. Updates are quite frequent.

In reply to by Jim Reynolds


That would certainly be a serious limitation with your workspace. Unfortunately, you didn't give a lot of information for us to investigate this (it's not a problem other users have reported and we use the plug-in ourselves but haven't seen the problem). If you'd like to give the plug-in another go, please raise any issues on our support forums where you will get a speedier response and we should be able to resolve the issue. Please include as much information as possible when raising issues and attach the workspace log, which is often helpful.

It would be nice if the JS formatting supported alignment  like PHP does.

and the PHP alignment could use some improvements for more complex scenarios. like double columns per line. Support more assignments like ".="

alignment across minimal switch cases..

and it would be nice if whitespace removing can happen on save instead of only on format. Cuz I don't want to format always, but I do want to remove whitespace always


In reply to by Gareth Pursehouse

Thanks for the great comments on CodeMix. Regarding formatting, whilst we may be able to do more on this in future, the formatting is really down to the Visual Studio Code extensions that are installed as these provide the editor functionality. CodeMix provides a way to use that functionality in the eclipse platform. For JavaScript, we install the Beautify extension by default but, for example, you could remove that and install the Prettier extension instead, which may have better functionality for some developers.

So please do browse for other extensions that may suit, and do let us know of the good ones that we could consider to include as standard. I'm sure extension developers would also love to hear ideas from users of their code.

Thanks again.

I'm using CodeMix with Webclipse plugin on Eclipse Oxygen. 

It works great except one important feature. I can't Ctrl + click on elements anymore. 

On HTML files and TS files (opened with CodeMix editors), clicking + hover will display a popup with the element definition but if I click on the element, nothing happens. I am not redirected to the element definition. Sometimes my cursor just moves to the element declaration if it's in the same file but if it's not, nothing happens at all. 

This functionnality works with the Webclipse editors.

This actually only happens on a big project. I have another small Angular project for which Ctrl + Click works perfectly with CodeMix Editors. 

In reply to by Thibaut accav

I ended up reinstalling Eclipse on my computer (delete all eclipse related folder, download and install Eclipse Oxygen 3, install WebClipse then CodeMix). I imported my Angular project and it seems to work now. I can Ctrl + click on elements and it takes me to the definition in both HTML and TS files opened with CodeMix.

For +15 years I have been developing with Java and using Eclipse, although in the last 18 months I have been moving into modern development using Angular, PHP along with a bit of Python and React. At the beginning with this transition, I experienced frustration in trying to properly run supersets in Eclipse - such as Typescript - as well as for debugging PHP and Python code; mostly because tools and dependencies setup took too many hours for my projects to work, and there was - usually - at least a couple for issues to research in how to fix them. It was a hideous nightmare for me! But then I started to hear – from a fellow developer – about CodeMix as it has a lot of out-of-the-box support for the coding I was developing. So, my first try with CodeMix was with Python as I was running out of time to fix a Python script that was pulling and processing data from a Web service. I got amazed as it is easier to get CodeMix set up into Eclipse and - even better - a lot faster to run and develop with - I got my Python script fixed in less than an hour thanks to the CodeMix debugging configuration! I got so impressed that now I am using CodeMix for my PHP, Angular and React projects as well. To set break-points and walk through variables and values is one of the best great things for me as CodeMix makes my developer life a lot easier. Most likely if you try it out, you will love it too! ^_^

Time-based licensing simply means that when i open an old project, I spend the next week trying to get the environment working - and then forced to reinvest / re-register / re-located keys & logins - only to use the tool for a couple of days for deployment or quick update.

Additionally, its often enountered where the publisher forces an update during the re-reg process & may or MAY NOT be backwards compatible with resusitated projects....

= ClusterF for smaller ops.

Version-based licensing is the way to go... working for atlassian.. once I lock in my environment, I'm not screwed with I move it to another VM 2 years later. I purchase a license that lasts FOREVER with the benefit of 1yr of updates. Those who stay on the cutting edge ( AND use the tool the most ) will contribute more funds out of necessity [&  rightly so due to usage] - those who infrequently use the tool aren't enslaved to the same burden.

This is tantamount to ransomware IMHO.. this said, GREAT tool.

In reply to by SiloSix SiloSix

First off, it’s great that you like the product!

Completely understand that different people prefer different models.  By providing a subscription model, we can allow many people to have access at a low price point instead of a higher cost for just a few.  The ability for getting just 1 month for $5 means you can also just get a license for that limited time you need to come back to the project instead of purchasing another year.  I realize perhaps not in exact alignment with your perspective, but we did try to make it accessible!

We also like that subscriptions give everyone access to the latest features they need, unlike version-locked licenses where companies can force a pay-event for users simply by restricting support for Feature X to an upgrade, such as "upgrade for Angular 6 support."
