Saving Tiddlywiki Classic on Chrome (browser) and Chrome OS

[Andrew Ashling]

Okay, if this has been mentioned already, just ignore me or delete this entry.

I just installed Chrome on my fresh install of Mint Petra, Cinnamon Edition (based on Ubuntu 13.10, IIRC)

I work with a cluster of linked TWs, grouped in one folder, together with TddlySaver.jar.

I managed to save changes in TWs by installing a plugin called User-Agent Switcher. Basically it can make Chrome behave as Firefox, Safari, Opera, IE and a few more.

And it works… The post I found this in, was actually about Chrome OS, so, since it works on Chrome browser, it should also work on Chromebooks,

The behavior is slightly different though than what I'm used to. Instead of saving a new copy, it saves the changed file over the old one.

I give this information as is, in hopes it can help someone. I have to stress though that I'm hardly a specialist, so if there's any interest, some people with more knowledge and experience than I have should try to replicate my findings.

Cheers,

Andrew

Thank you for this.
I'd tried using TWC with Chrome and with Chromium both under openSuse Linux and grew increasingly frustrated and eventually have up and went back to Firefox.

The saving a single file does solve the problen of copies being spawned all over the place, but having the ability to backup as a checkpoint would be nice.

Hi Guys.

I managed to save changes in TWs by installing a plugin called User-Agent Switcher. Basically it can make Chrome behave as Firefox, Safari, Opera, IE and a few more.

And it works… The post I found this in, was actually about Chrome OS, so, since it works on Chrome browser, it should also work on Chromebooks,

The current TiddlySaver should work everywhere without any assistance. It was announced in this forum but is not yet included in the TWC download as we were trying to make sure everything works before committing. As far as I know it works everywhere and in all TWC versions using all Java versions except update 45 (which can use the unsigned jar included in the announcement). The single reported problem does not appear to be TiddlySaver related.

If the current TiddlySaver DOESN'T work for your setup but changing the user-agent makes it work then there is a bug in TWC that needs to be fixed, so please do try out the current TiddlySaver and report back.

The announcement contains more information and links to the jar.

It would be very helpful if anyone who has experienced troubles with TiddlySaver in recent years would try out the new version and report back. Then we can get it into the official release. Thanks.

BTW, default behaviour with the lastest TWC (2.8.1) -- at least on my system -- is for a backup with the current date to be saved and the original filename to be overwritten with current content. This behaviour is controlled in 'Options' using the 'SaveBackups' option.

Cheers, Paul.

Hi Paul,

The signed jar indeed does save in Chrome. (on Firefox I use TiddlyFox). So probably it will work on a Chromebook as well, which is great news.

However I don't get the standard backup behavior using TWC 2.8.1. The file is saved, but NO backup of the previous version is made.

Hope this is enough info. If not, ask away.

Cheers,

Andrew

@Andrew.

Thanks for the report. As to backups: did you check your option setting?

[Andrew Ashling]

The same TWs save & backup with TiddlyFox.

Which options, by the way?

[Paul Levey]

The 'SaveBackups' option in the sidebar 'options »' slider. (Apparently these options are saved on a per browser basis, so they could be different for different browsers.)

[Andrew Ashling]

I checked, and in my TW's both SaveBackups and Autosave are checked.

(Also when starting up I get an "error when including" message about the linked TW's. They link fine however.

[Paul Levey]

Thanks Andrew.

I am unable to recreate your problem in my own setup (Chrome 33.x portable on Windows 7). It saves both files automatically and manually, though I notice it doesn't save the 'Autosave' option and I have to reset it ... this is not a TIddlySaver issue though.

I am focused on trying to make sure that TIddlySaver works so the new version can be released and am not too competent on other areas of TW operation.

Your observations are important though as it looks like TWC in Chrome has some bugs that are obviated by changing the user agent string (therefore probably browser sniffing errors).

Perhaps Eric will look into it.

Cheers, Paul.

[Andrew Ashling]

Glad to have been of help.

Let me add that it was the same behavior whether I was using "Chrome as Firefox" with the User-Agent Switcher or Chrome with the new TiddlySaver.jar

No thanks necessary, by the way. I've been using TWC at least for six years (more like eight, I think). I'm not all that technical, but I'm glad I can contribute something at least.

[Andrew Ashling]

Paul,

I'm sorry, but it seems I sent you on somewhat of a wild goose chase.
I took some more tests and the new TiddlySaver.jar makes backups just fine.
Embarrassingly enough, I must have looked in a wrong directory. But this time I'm positive: all works fine.
Sorry again.

[Paul Levey]

:0) No worries.

Hello Andrew

I am following your post from half a year ago. 

I mainly use a chromebook. Most of my docs are on the cloud and I like to access tiddlys from different browsers/computers too. I am using TW5, but it's more important for me to be able to edit and save easily on any computer, and I will switch to TW Classic if I can save tiddly files onto a cloud directory without manual intervention. ie I am waiting for TiddlyChrome that replicates TiddlyFox functionality. But I can't wait.

But I can't follow the conversation about  / understand  the plugin  User-Agent Switcher,  Will the plugin allow me to do simple saves - akin to tiddlyfox - with TWC  in ChromeOS (chromebook : where not .jar files can run) ?

Thanks

​Hi Daniel,

I'll try to answer what I've found out​ meanwhile, but please remember I'm just a user (over seven years now), and by no means a programmer.

 

I mainly use a chromebook. Most of my docs are on the cloud and I like to access tiddlys from different browsers/computers too. I am using TW5, but it's more important for me to be able to edit and save easily on any computer, and I will switch to TW Classic if I can save tiddly files onto a cloud directory without manual intervention. ie I am waiting for TiddlyChrome that replicates TiddlyFox functionality. But I can't wait.

​The only way I found up until now is a hosted solution​ like TiddlySpace and the likes, but personally I'm not partial to those. IMHO there is a need for a very simple module you can deploy on your own domain to host TWs. I know there exist (or existed) some solutions but they were not what I would call simple.

If you only need to consult your TWs you can simply put them in the Public folder of DropBox. They're read only but otherwise fully functional. I tested this the other day with my cluster of 13 linked TWs. And of course they're up-to-date up until your last edit from another device.

My problem with a chromebook is that (whenever I get one) I will be using it where there is no wireless connection. I'm almost certain you can access TW in read only mode from the SSD. What I don't know is whether you can synchronize the chromebook SSD with DropBox.

I realize none of this meets your requirement to be able to modify your TWs with a chromebook and keep them synchronized over multiple devices.

But I can't follow the conversation about  / understand  the plugin  User-Agent Switcher,  Will the plugin allow me to do simple saves - akin to tiddlyfox - with TWC  in ChromeOS (chromebook : where not .jar files can run) ?

Not to my knowledge. As far as my limited understanding goes the User-Agent Switcher only shows you the pages "as if" rendered by another browser. Useful for testing css and html, but I don't think the full functionality is replicated.

Myself, I need a cheap, light laptop with a half decent screen, a decent keyboard and about 8 hours autonomy on a full battery. To counter chromebooks, Microsoft is encouraging manufacturers to produce low-spec, low-cost notebooks, similar to chromebooks but running Windows 8.1.

I'm looking into those, and I expect a few will turn up around the Holidays. (I would put a light Linux distribution like Lubuntu or Peppermint on it.) This would allow me to use Firefox for TW and Chrome for a few apps I like.

Sorry, but I can't provide a better answer.
