  • Read/Write AS3 Shared Objects – Capable of reading/writing Flash 9 and newer .sol files.
  • Read/Write AS2 Shared Objects – Capable of reading/writing Flash 8 and older .sol files.
  • JSON Import/Export

.minerva with an AS2 .sol file open

.minerva with an AS2 .sol file open

.minerva with an AS3 .sol file open

Will it be possible to edit and save sol files with .minerva in the future?

January 11, 2009

If the demand was there for it. I’ll put it on my todo list, right now i’m in the middle of some updates to SideShow and Aroma.

May 4, 2009

Do you plan to release it as opensource. I am interested in to look your AMF parser code. Thanks.

May 8, 2009

To tell you the truth, the first version I made I built the AS2 parser from scratch. With the AS3 updates, I pulled a lot of logic from the AMFPHP project which IS open source. AMFPHP

.minerva is a handy tool, but with testing you go through the process of “open>browse for sol” repeatedly, I think the ability to drag and drop a sol from the OS into .minerva would eliminate this and make it even more useful!!

[…] .minerva For .minerva I upgraded it’s support of AMF0 custom classes and typed objects. It now supports dragging and dropping files into the UI to speed up debugging. […]

[…] all using a ByteArray, so I looked for a tool to do the job. I found a handy AIR application called Minerva, which can open a *.sol file and display its information. As of this writing, the current version […]

September 18, 2009

Very cool.
I’d also be interested in the AMF parsers, releasing them as opensource would be absolutely great! But I’ve done some AIR apps also, and I know it’s not an easy decison…

Please keep me updated!

September 18, 2009

I would probaly consider doing that. I got most of the v2 logic from amfphp which was open source to begin with. Only makes sense to share! I’ll let you know when I get it up, mostly likely on Google Code or something.

September 21, 2009

That would be really useful!
I can help you write the code to handle updating the SOL.

Please ping me as soon as you can (directly if you want, I’m working on a project that would be way better with the help of such a lib)!

October 3, 2009

I found one error while formatting a Javascript file:

var A = 1e-10;

is wrongly formatted as:

var A = 1e – 10;

October 3, 2009

I don’t see whats wrong with that. Looks correct to me.

December 5, 2009

Very nice! I used to use .soleditor but they never updated it for AMF3 so I finally just uninstalled it.

I would add my vote for being able to write to the .sol as well. The data fields are editable so I thought this was feature at first glance.

Thanks for this.
– Aaron

December 5, 2009

Oh and also, “open with” functionality would be great, so I could set up file association with .sol files. In fact I’d be more than happy to contribute that code if you would be interested. – Aaron

January 7, 2010

Henk, I finally realized what you meant, and updated the JS Formatter engine. So your math error should be fixed now

January 8, 2010

good work!

January 20, 2010

Gabriel, I can open and edit .sol files, but cannot get the changes to save. Even the “save as” function doesn’t create a new file. Any help? I have updated Air to the latest version. Thanks!

February 11, 2010

I’ve enjoyed using your tool and though I would comment on an issue I’ve encountred. When I edit the loaded .sol file I’ve only been able to persist the changes using the “save as” option from the menu. Though the changes do appear in the new .sol file, I’ve noticed that all Number type data from the original .sol are converted into Integer types in the new file.

Thanks for sharing your tool.

February 25, 2010

Thanks for the tool. What would make this really useful for me, would be if it read the contents of your shared object directory directly (by adding that path in), and poll the contents frequently to reflect changes in the .sol for viewing/debiggun purposes.

March 13, 2010

“save as” function changes “filename : AMF3” into “filename.sol : AMF3”.

And, cannot “save” function work on Windows7 ?

March 15, 2010

Would it be possible to add a sort option for the shown properties/variables. I have some very complex sol files and it is awkward to look through long lists for the desired item

Otherwise thanks a lot, one of the few editors/viewers that actually works

March 15, 2010

@elvis Maybe i’ll add a refresh button to reload the file

@Jap The first part it always adds an extension when saving. That’s how the program recognizes a SOL file. I don’t understand the second part of what you wrote.

@JJ i’ll look into that

@cmacleod I’ll check on that too

March 15, 2010

Is this App tested on Mac OS? I open it and only see an empty pane.


March 19, 2010

Thanks for the sort option

March 19, 2010

I have had a couple of problems with the new version, both to do with Array() entries
a) minor issue if you expand the array to view it’s entries it always expands the first (0) entry. If I then minimise the element 0 it closes the entire Array. I just wants to hide the element 0 so I can see the others

b) If I expand element 3 or more entries at once (say 0, 1, 3 or whatever) the application hangs and I have to terminate it

If it matters the data structure is a custom class that contains an Array of another class. I can send you the sol file if you desire.

March 19, 2010

(slight typo above)
The hang is if I expand 3 or more Array() entries at once.

March 22, 2010

I’ve been having a problem with the utility where after making any changes to a .sol file and saving it, the .sfw that accesses it no longer recognizes the file. Any help would be appreciated.

March 23, 2010

hi, a little bug ? :
when i save a SO -amf3- (with version, your application add “.sol” to the name of the sharedobject
not the file name, the internal name : SharedObject.getLocal(“mySO”,”/”) , after saving “mySO” become “mySO.sol” …. )
so it is unusable ;)

March 23, 2010

Bah, the devil is in the details. Thanks alan! I’ll have an update hopefully tomorrow if work isn’t too hectic.

March 30, 2010

Ok so I finally took the time to really go over all the details and make sure everything (that I could tell) is up to par and fixed. As you can tell from the change log quite a bit was fixed. Please try out the latest version and let me know if anything is still wrong.

March 30, 2010

Thanks, the array issues are fixed, a couple of thoughts while checking
a) I have a couple of undefined types in my sol file (a bug) but I cannot fix these to Number. Is it possible to change the type of an entry?
b) also would it be possible to add new variables, or too complex to do?

March 30, 2010

No, it’s all quite possible. It’s just a matter of creating an interface that isn’t too complicated. But right now I’m just trying to fix bugs. Flashbug has some problems I need to get fixed. Maybe after everything is said and done I can get back to .minerva and add that capability. Trust me, its on my to-do list, just don’t have much time =p

April 8, 2010

Lollie, I have the exact same problem with the same exact game; I just used cheat engine instead. It would be awesome if there was a help section that can clarify what exactly are the errors and ways to solve them. I looked it up and got this:

ReferenceError: Error #1065: Variable LoadTest is not defined.
at global/flash.utils::getDefinitionByName()
at … (rest of stack trace deleted)

1065 Variable _ is not defined. You are using an undefined lexical reference. For example, in the following statements, the statement trace(x) generates an error because x is undefined. However, the statement trace(y) doesn’t generate an error because y is defined: trace(“hello world”) trace(x) // x is undefined var y trace(y) // No error, y is defined.

In this case I was trying to dynamically instantiate a class by first finding the definition of that class and then newing it. Something like this:

public function createInstance(className:String):Object {
var instance:Class = Class(getDefinitionByName(className));
new instance();
It turns out the reason why the error was being thrown was that in my Flex Application I didn’t have anything which “used” the class. In other words the compiler thought that the class was left over junk and didn’t include it in the compiled swf. By adding in a use of it, everything started working. As example use would be something like:

private static const loadTestRef:LoadTest = null;

Source: “Daniel R.: Flex 2 Runtime Error 1065.” NeoPhi. Web. 08 Apr. 2010. .”

Don’t know what the hell that means.

April 17, 2010

Similarly I have a significant error
a) load my sol file using minerva
b) change a field, click save changes on the field, then save via the File Menu
c) exit minerva. Re-run and open the same sol file and I get the error
AMF0::getObjectReference – Error – Undefined object reference ‘512’

I have seen this error a couple of times, different references (also seen 768). My sol file is quite complex, many objects and arrays and many variables

May 14, 2010

May 31, 2010

Thanks for the bugfix, a small issue with the latest version:
Previously I could right-click on a .sol file anywhere (generally posted with a bug and copied to my hardrive somewhere) and .minerva would open the file just fine.
Not anymore, .minerva opens but the file is not open. A pity this was very useful.
This also happens if the file is in the standard folder, so it is an issue with the rightclick open process. The program works just fine otherwise

July 19, 2010

Is there going to be a fix for the sol errors?
It is very sad indeed that such a brilliant program is ruined by the fact that it destroys perfectly fine sol files :(

July 21, 2010

There’s a pretty glaring error that causes .minerva to incorrectly save(or parse, I’m not sure which step it’s failing at) .sol files. It causes .minerva to save files that if you were to re-open them, you get an Undefined object reference error.

If I’m not mistaken, isn’t that error caused when the AMF0 parser finds a ‘reserved’ variable with a null value?

I’m using flash 10(debug version). AMF0 shouldn’t really be parsing the files, since they should all be AS3 to my knowledge. Perhaps include a method in the future to force-specify which parser to use?

I have a sample .sol that I could upload to you if you wish. It opens fine the first time, but if you save it(even without changing a thing) you are guaranteed to get the Undefined object reference error. After saving the filesize of the .sol is reduced from 6.41k to 2.60k as most values are lost.

July 21, 2010

That would be awesome if you could email that to me. I’m sorry I didn’t catch this error. To be honest I only use minerva to read sol files not really edit them. So I only hear about these issues when somone speaks up. I’ll get to it asap. Or if you want you can post an issue/bug here: http://code.google.com/p/cv-minerva/issues/list

I’m going to start using Google code to keep track of bugs so people can tell when something has been fixed. Thanks!

January 11, 2011

I am wondering if there is going to be a feature to manually add an integer to an array rather than only being able to modify pre-existing arrays

January 11, 2011

eventually, but not right now. pretty busy with life at the moment. When i get some time i’ll add some new features.

January 26, 2011

I have a question – how does AIR read/write to a shared object from another domain? Does it use the Shared Object class to do it, or do you have to load it as a text file?

January 29, 2011

I load it as a binary file and manually edit it. You usually can’t edit it from another domain which is why i don’t use the built in Shared Object class.

February 13, 2011

I get this error:
AMF3::readData – Error: Undefined AMF3 type encountered ’13’.
Could you fix it, please?
Thank you!

February 21, 2011

You’ll need to post a bug on google code with the sample SOL file. Otherwise i’ll have nothing to work with or keep track of. Thanks

Is there any way to get an older version of .minerva? I upgraded from 3.2.6 to 3.3.0, and now I am unable to edit .sol files without the contents of the file getting wiped out.

April 2, 2011

Could you send me the sol you are trying to edit? Post a bug issue here so I can keep track of it: http://code.google.com/p/cv-minerva/issues/list

I’d rather fix the issue than require people to use an older version. And to answer you question all versions are on the server, just change the url to the correct version. (i.e. http://blog.coursevector.com/downloads/Minerva-3-2-6.air)

April 4, 2011

Could you guys please make it harder to save changes?

I’m loving how I have to click in multiple places to save data, and that if I navigate away without clicking save my changes are lost.

Still I fear that some of my work may be inadvertently recorded.

You guys have boldly innovated in the field of unintuitive and unusable software, but I feel you need to go a bit futher to complete your vision. You can do it guys, I have faith in you!

April 5, 2011

Complaining about free software instead of giving constructive criticism. Stay classy ‘Bob’

April 13, 2011

Can you please add the ability to drag data types into custom orders?

It would really help in organizing things.

April 16, 2011

^ Can I please have a reply to the above idea?

April 16, 2011

That would be kinda complicated, since i’m using the Flex tree to display the data. It’s not entirely flexible (excuse the pun) in terms of doing custom things. I’d have to do a lot of work to customize that component to pull that off i think. So for now, it’s not a feature that will happen anytime soon. sorry.

April 16, 2011

Ok then

I appreciate the answer and can’t wait to see what you do with this program next.

April 20, 2011

a function to add and delete data instead of just editing it would be very usefull

April 22, 2011

I’ve been looking into it. But i think again, i’ll have to customize the Flex Tree component to get there. Currently working on an update to flashbug then i’ll refocus on minerva.

April 24, 2011

Hi there! I recently downloaded minerva to edit some .sol files for a flash game I play.
All the files show up, and I am able to edit the things (such as amount of money, levels, etc.)
However, none of my edits are showing up when I play the game. After I edit the things, I click the “Save Changes Button”. After that, I click the “Save” button on top, and I exit Minerva. None of my edits showed up, so I look at the file on Minerva again, and everything is back to how it originally was. Am I doing something wrong when saving my edits?

April 25, 2011

Could you upload the sol you are trying to edit to the bugtracker? Post a bug issue here so I can keep track of it: http://code.google.com/p/cv-minerva/issues/list

April 26, 2011

Fantastic app, thanks so much! Makes those quick sol edits nice and hassle free.

I was curious if it’s possible to import from json? It’d make my life so much easier when moving nested arrays around.

May 11, 2011

Thanks a lot of making this tool. It’s extremely useful and way better than any of the other editors I have used earlier.

Minerva fail to load *.sol files from tankionline.com site with message «AMF3::readData – Error : Undefined AMF3 type encountered ’17’, at position ‘336’»

June 5, 2011

@Max please post bugs to my bugtracker, i just mentioned it two posts above. I’m not going to fix that issue, i don’t even have a file to work from.

June 29, 2011

Hey man, one question : can we add new values to sol’s? And how?
If no, will it be available in the future?
I know other programs that can do that, but they won’t open 90% of the sol files…

July 4, 2011

I plan on it, but i’m too busy to get to that at this point so please be patient. Thanks!

July 25, 2011

You have the ability to export to JSON, could you support IMPORTING JSON? This would be very helpful as it is much easyer (for me at least) to edit the data from JSON then using the flash GUI.

November 14, 2011

@gabriel: Thanks for giving to the community. Great help.

December 1, 2011

Do you have an ETA on th feature to add and delete data from anywhere in the sol including arrays?

December 2, 2011

Not really, I made some progress on it a long while ago but ran into a road block. The Flex tree component doesn’t easily allow you to add or remove items anywhere inside. I didn’t really want to rebuild a good tree component nor do i really have the time so i kinda put it on the back burner for now.

June 8, 2012

Hi, I am having a quick question (probably a novice one)

I have a AS3 app saving in sharedObjects.
I would like an AIR app (independent) reading the flash app’s shared object files (which is not currently), since they don’t share the same location.

Can you please advise? For you that should be the easiest thing…
By the way I love your app, it locates the flash shared objects and reads them all!

Thanks so much
I would appreciate any help!

June 11, 2012

This site summarizes what you can do to specify where the shared object can live (to share between multiple SWFs): http://jaycsantos.com/flash/the-trick-to-using-sharedobject/#tip2

But the problem lies in sharing a shared object between a web page and an AIR app. If you look at that site it’ll show you that AIR apps and webpages are more or less sandboxed into a folder that they can search for shared objects from. So unless you copy the shared object into yuor AIR folder somehow and it allows you to read it you might be stuck manually reading the shared object (bit for bit).

June 18, 2012

June 18, 2012

You can’t. I haven’t updated it to support that yet, I work on it in my free time which I have little of lately. Sorry! =/

July 31, 2012

Are there plans to be able to add/delete items? At least adding more items to the same array shouldn’t be a problem.

July 31, 2012

I did have plans but honestly minerva is on the back burner in terms of priorities in my life. i think if I ever do get some time to chip away at it I might totally redo minerva and update it to a more modern platform. But the current issue with minerva, the reason I haven’t added those ‘easy’ features is that the tree component that displays the structure of the file doesn’t easily allow you to add or remove items. That component itself is incredibly complicated and not something I wanted to rebuild so I kinda left it. But if/when I do re-do minerva and it’s interface I’ll totally add those features in…..someday.

Any suggestions?

Try following what they did on this post: http://forums.adobe.com/thread/772195

September 1, 2012

Hey Gabriel. None of that stuff worked but I realized it wasn’t anything to do with the app, most likely it was just Air and my Win7 64 bit comp not playing nicely together.

I actually found a great workaround on the stack overflow forums though.
So here’s the reply I left on the question I made in the Adobe forums:

“Oh hey I found an AWESOME workaround on Stack Overflow.

Turns out if you can find another computer to install the app on, you can take the folder it makes (in my case the course vector folder) in Program files (windows 7 64 bit is the x86 program files) and copy it.

Then assuming you have Adobe Air installed on the computer you wanted the app on (which if you spent a few hours trying to install an adobe air app without the program then I can’t help you…) you can simply paste the folder into the same location and it’ll work perfectly! X3”

This is a general Adobe AIR issue. Try googling the solution for that. From what I could find, you may need to uninstall and reinstall both the application and Adobe AIR to resolve this.

January 30, 2013

Could you post an older version that will run on Linux with the 2.6 Air runtime? Adobe’s not supporting Air on Linux after 2.6.


January 30, 2013

v3.3.4 and below supported AIR 1.5, so you can just download that version. Be warned, the auto-update will nag you every time you open it up.

I’m trying to attempt the “cheat” for a flash game I read into in the “website” field. Upon attempting to open the save files of the game, I get this message;
“Data Length Mismatch
File Length:64382 Data Length:64290”
and if I save the files, even without making any changes, it automatically causes the game to not recognize them, so they’re corrupted or something like that. I don’t understand, and I have searched a lot into the Internet without finding anything. I’d really appreciate it if anyone could me, as I don’t know how to work with this kind of thing but have attempted to do so without avail for about five days straight.

May 10, 2013

If you could email me the SOL file you’re trying to edit I can take a look at it. Otherwise I really can’t help you much until I see the file.

Wow! A really fast response! I’ll email it to you shortly. Many thanks!

Great Editor, you need more praise, It’s wicked awesome that it is free too, you should get some cash for this. You should do a pro version that costs like 5 bucks but adds features like Adding bools and values and it can potentially turn into a new IDE to blow Stencyl out of the water. This application already owns existing .sol editors. I’m sure have been getting some guff from greedy game developers getting their games exploited, but as a game dev myself I have to say “Good work!”
If there is an exploit, let it be known and used!

Thanks for the compliment. I can’t say I have as much time as I’d like to work on this. But I’m glad people still appreciate it and use it. Maybe if i ever get some free time I might work on a pro version like you suggest. Thanks again!

Hello,Your sol editor is awesome,can you please add a “delete object” and “add object”? this would be useful in some games (Like the arena mode of Madness: Project Nexus),
Also,this is another useful tool than cheat engine.

August 20, 2013

Hi again,sorry for the double post,but I have another suggestion :
Instead of making a paying pro version you could make it free and add a donate button,your fans will donate if possible but they’ll still be able to enjoy your stuff (this helps to restore the progress in flash games)
Great work,please make more versions and add more features.
Other possible features: Maybe an undo button.

August 21, 2013

There is a donate button… =(

In the about window if you click on the ?

We can export sol files as json. Could you add the option to import json files and export them as sol?

Is this still being developed? I love this program. I got the latest version running under Linux by installing the windows version of adobe AIR in WINE and then running the AIR Application Installer with the minerva 3.5 package as an argument. It is a great utility, and I really hope you haven’t given up on it. If you have, would you consider releasing the source code?

April 12, 2014

Would you consider releasing the source code if you have abandoned this project?

I got the latest version working in linux with WINE and the latest windows AIR. I ran the AIR app installer with the .air package as a parameter. You have to give the full path to the program, which is the only annoying part.

April 14, 2014

I haven’t given up on it but it’s more of a pet project than anything. I am planning to update it but blocking out a big enough block of time to do it is difficult. I’m sorry about the Linux deal, but that was Adobe shifting away from Linux towards mobile. I don’t personally use Linux. As for updates to the program, what are you looking for? While minerva handles sol files FAIRLY well, it doesn’t do it 100% correct. Adobe hasn’t released any updated documentation in a long time. So I end up spending a lot of time doing trial and error, which I don’t have right now.

April 14, 2014

I’ve looked into it, whenever I get time to update minerva I can try to add that in. Although it’s not as simple as that. Converting complex objects to a string is simple. Converting a string and guessing what complex objects they are supposed to be is a pain.

April 25, 2014

Good to know! And it’s nice you respond to comments :D

Anyway, I mentioned source release because I’m learning C and would like to analyze the logic and make a (probably CLI based) version that will run natively in Linux. Still, thanks for the tool. It’s really useful ^_^

April 25, 2014

The one thing I would like that doesn’t seem implemented is adding my own variables/arrays to an SOL. I think you mentioned it would just be a matter of adding in the UI code.

And where is this Adobe documentation of which you speak? I haven’t been finding it. Maybe I just haven’t looked hard enough, though.

April 25, 2014

Also, I have OS X and windows, as well as AIR SDK, so even if I don’t make a C port, I could possibly dedicate some time to this program as well and send you patches with my changes. Might speed up development if you want to let it. Or you could just let people fork your code and go their own ways with it. Anyway, main thing is, I want to know how SOL’s work and be able to manipulate them.

April 26, 2014

Seem to be having the same issue as “Code-illiterate” with the Data Length being mismatched upon opening the .sol file to be played with:

Data Length Mismatch
File Length:882489 Data Length:882375

I can then play with the fields and mod what ever, but when i attempt to save it Minerva goes into “Not Responding” mode. Utilizing the latest version 3.5.0 with the latest version of AIR installed. I read in the comments that you’ve put Minerva on the back burner of projects, but haven’t able to pull up any hits when searching the past few days. Thanks again for all the effort you’ve put into this program, as it is a wonderful piece.

Okay, i’m a bit stuck, every time i try to download, the installer fails, stating theirs an error in the installer.

Now, I had this installed for ages, until my god damn fool of a brother decided to reformat the laptop…..is their any other way to get Minerva?

May 31, 2014

Sent you an email michael

June 3, 2014

I think I have the same problem as Michael. Whenever I try installing, I get the message “The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author.” Is this a problem on my end?

June 4, 2014

I spoke with Michael, it ended up being an issue on his end. Adobe AIR can be a pain on installers. Keep futzing with it, and if you have trouble just shoot me an email (or comment here again)

June 15, 2014

Just a tip for any other Linux users – if you want to run this without Wine using Adobe’s last native AIR release, version 3.3.4 does work. This is available at http://blog.coursevector.com/downloads/Minerva-3-3-4.air , thanks to Gabriel’s usage of versions in filenames. I’ve legitimately seen somebody use MD5s as download identifiers, so this is a welcome change from *that*.

June 21, 2014

I’ve been messing with the installer like you suggested, but I get the same error with the installer package…

June 22, 2014

You should add a Link to an older version ( http://blog.coursevector.com/downloads/Minerva-3-2-6.air seems to work) to the description. Reason: Adobe Air Version 2.6 (32 bit) is the last one Linux users can install, see http://helpx.adobe.com/air/kb/install-air-2-64-bit.html
The current minerva requires Air 3.1, so it won’t work, but older versions (like 3.2.6 above) still work. While not as good as the current gen, it’s the only one Linux users can use, so it might be good to link it somewhere

June 25, 2014

I tried reinstalling Adobe AIR several times and the installer package gives the same error. Can I know what fix Michael used to get his working?

July 5, 2014

Dude, we asked you for an add variable feature for FOUR YEARS, and you gave us nothing.

July 5, 2014

Mostly because minerva pays me nothing and I have an actual job(s) besides work on minerva. Also the Tree component used in Flex is pretty crappy and adding in things at random points in the tree and specifying the data type and having it all coalesce into a coherent object was a bit of a pain. But all is not lost, and I still keep track of the issues. I’m currently working on a online/web version since Adobe AIR is becoming more work to maintain than it’s worth. I’m going to AIM to have the ability to add in objects/variables from the beginning in this new version though.

July 21, 2014

Glad to hear that – a web version would be nice, I think. Definitely more portable.

July 26, 2014

I hope we get it soon then; trying to run adobe air on ubuntu even eith executable permissions has not been fruitful; tried installing air then minerva so I could extract the files from it and copy/paste to my own comp

August 12, 2014

I have the same problem as Rock, I can’t install the program (I’m running into the same ‘The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author.’ error). I”m running Windows 8, any way to get it to install/run? I have the .exe file from a previous installation on an older laptop, but it keeps saying ‘This app won’t run on this computer’, any ideas?

September 17, 2014

The new online version seems to have problems with saving larger saves like around 50+ kb, and can there be a downloadable version of the newer one?

September 17, 2014

I didn’t have any trouble with ones that large, I actually tested it with larger ones. If you have a specific SOL file that is giving you issues please put in a bug in the bug tracker. Just go to the online version of minerva and click on the support button at the top and it will take you to the bug tracker. Enter a new issue there and upload the file in question and I’ll take a look at it.

And to answer you about a downloadable version I’m going to say no. The issue is that it was more hassle to maintain compatibility with where it installs than the program itself. Adobe AIR requires a digital signature for each install, but they are only good for 2 years. I didn’t update some of my apps for years at a time and then was locked out from updating them because of the digital signature expiring. Then there were issues with Linux/Mac compatibility, etc. Having a browser version makes it extremely portable and easy to support. I don’t get paid for minerva, i have a banner ad now, but that’s not much. So having something low maintenance is my goal while still providing a great program.

September 29, 2014

I have the original offline version, 3.5.0 as installed from here a while ago, not since 4.0 was released.

Each time I run it it prompts me to download and install 3.5.1 but if you say yes it gets an error downloading every time.

Before you say to use the online 4.0 I do not intend to, I often use .minerva on a system not internet connected as well and prefer to use the one program.

This is annoying but that is all. If possible can you prevent the update notification?

September 29, 2014

I did that to notify people who do NOT visit the blog that a new version was released. Yes, it’s a bit broken that way, but it did get your attention. I did turn it off though. Also yes, I do suggest using the online version instead. Barring the initial loading of the site, it doesn’t use the internet for any of it’s functionality. I’ll be working on adding an offline mode to it so you would only have to load it once and be good to go.

September 30, 2014

Could we have a downloadable version of this, so I can run this off of a local server?

I really like this online editor, but I’d like to be able to use it when I’m somewhere where I can’t load the site.

October 16, 2014

I would like to echo the call for a downloadable version.

October 16, 2014

Noted, but I’m done with making Adobe Air apps. I spend more time fighting issues with it not installing or updating or the certificate expiring than updating my apps. Not worth it for a free application. So until there is a framework I can drag and drop html/js straight into an application (like adobe air should have been) then it’s just going to be a web version. Sorry!

October 26, 2014

I’ve updated minerva, the saving is fixed, i’ve added an offline mode (for browsers that support it) and you can now create new files directly from within minerva.

October 27, 2014

How the hey hey can I download Version 4 so I can get it on my PC instead of using this super awesome online version?

October 28, 2014

I’m glad you enjoy the online version so much! Unfortunately downloadable versions (Adobe AIR) is a huge hassle to maintain and because I update it so infrequently I got locked out of doing updates through AIR. So I said, this is stupid, I’m making an online version so it works anywhere. And you know what? It works pretty well. I’d say a more constructive criticism would be to say WHY you need a downloadable version, to highlight a deficiency in the online version. Because right now, the only downside is you can’t run a command line on it. It can go offline, writes better than the old one, works on Linux, you can pin it to your task bar to run it like an app in IE9+ and can import JSON. Besides, I’m a web developer, not a C++/Cocoa/Android/iOS developer. Why learn 34123412341234123 languages when HTML is taking over them all?

November 17, 2014

there seems to be a problem on the recent version when creating a boolean object.
here’s the error message:
Error: Undefined AMF3 type encountered ‘Boolean’

December 3, 2014

Hello! First off, great tool. Looks very clean and neat, pretty intuitive and relatively fast.
One problem though, I have trouble writing SOL files. I can load and edit them fine, but when I save the downloaded file is empty, so the content is not saved. Is this a known bug, and can it be fixed? Or any idea on how to solve this?

December 3, 2014

If you could, please post a bug report here: https://code.google.com/p/cv-minerva/issues/list
Note your specific browser version also please, thanks!

December 3, 2014

Did that. After some testing, I think it has to do with the large size (~1.3 MB) of the SOL file.

December 26, 2014

Hi. Whenever I open a SOL file, I get this error:
Error: Script file not found: js/parsers/SOLReaderWorker.js

I’m using Firefox on Windows XP.
I wonder if this has something to do with java.
Under the Add-ons Manager in my Firefox, I notice that Java Deployment Toolkit has a warning which read “Java Deployment Toolkit 7.0.710.14 is known to be vulnerable. Use with caution.”
When I click for ‘More Information’, a new tab open and it says “Java Deployment Toolkit (click-to-play) has been blocked for your protection… .”

My Firefox browser and all other add-ons [including Java Deployment Toolkit and Java(TM) platform SE] are up to date.
I don’t know what else to do. Can you help?

December 26, 2014

If you have an issue please put in a bug report at https://code.google.com/p/cv-minerva/issues/list . With that said Java has nothing to do with it. Java is not the same as JavaScript.It’s most likely a caching issue.

January 4, 2015

You keep saying that you would rather code html than any other language so therefore you will not make an offline version, but that is completely missing the point. People don’t care if this program is in Air or html, but what we need is a program that works offline period. Give people a zip folder / directory of html files they can download and run offline, even if it is in a browser. Browsers work offline, webpages do not. Give us the local html files we can run offline in a browser.

January 5, 2015

I believe you may have misread what I wrote. I don’t mind coding in other languages, I just don’t have time to support unreliable technologies such as AIR. Another misnomer is the fact you can’t use minerva offline. You can safely use it offline if you have a modern browser now thanks to app-caching. So yes, webpages do work offline.

January 6, 2015

It seems Unicode/UTF-8 is not supported. Or, if it’s supposed to, it’s not working.

When I use the Euro symbol ‘€’ in a string, save and try to open a file, I get an error message:
RangeError: argument 1 accesses an index that is out of range

Note: The program doesn’t display an error message when I save the file, but it produces an invalid file instead.

January 6, 2015

… save and try to open the file …

January 6, 2015

To all who are looking for the source code: It’s available here.

You can also post issues overe there, I missed that just now. Sorry about that!

January 11, 2015

I, like ‘offline’ and others, have been unable to get Minerva 4 to run in an offline environment. As in a standalone computer system. As in computers with no internet connection, ever. As in computers that can only play flash games or applications brought to them on usb drives. The browser will open .swf, .htm, .mht, etc.., but only if another computer downloads them first. The air installer and minerva air files work in this situation, but the new online only version of minerva cannot. If I have missed something and there are instructions to use the new minerva in this situation, please let me know. Otherwise, ‘offline’ was correct that webpages that cannot be saved to files cannot work in an offline environment. Could you maybe turn minerva into a browser extention .xpi or something similar?

Saving causes this error:
Error: Undefined AMF3 type encountered ’57’

May 8, 2015

Can’t seem to download the download version- say’s the installers broken?

May 18, 2015

Not sure what you’re talking about. The main link goes to an online version of minerva while the archived links still work.

June 23, 2015

So, there is no way to get a downloadable version of the latest Minerva to use in an offline environment? It’s all online and nothing else?

July 22, 2015

cant change values in this program

July 22, 2015

Ok. How do you honestly expect me to fix anything without details? There is a support button in the top right of the web app to submit issues. Please use it, thanks.

July 22, 2015

There are download links at the bottom before the comments to all the previous AIR versions.

August 22, 2015

how do you install the old versions, i only got a .rar files with a .swf files and some other things but i cant figure out
how to install it

August 25, 2015

Is there any way to rearrange the objects that appear in an alphabetical order? The .sol file I edit used to list them down alphabetically, but now it rearranges them in a seemingly-random order that makes it hard to look up objects short of manually searching them one by one invididually.
