Rather than providing the DMG as a download, why not have offer the qlgenerator file as a download or as part of the repository so that we can curl it?

That way this plugin could easily be installed from the command line, using something like:

cd /tmp
curl -O https://raw.github.com/whomwah/qlstephen/master/QLStephen.qlgenerator
mv -r QLStephen.qlgenerator /Library/QuickLook/QLStephen.qlgenerator # possibly needs sudo? untested
qlmanage -r

Hello:

Thanks for sharing your code. Is there any support to disable line wrap?

Can't get it working on the latest Yosemite beta (QL displays standart system preview):

Would it be possible to have this extension support .dotfiles? That would be really useful functionality.

Hi!

as I try to quick look such file

cat > test << EOF
1.1 Видим возрастание (вроде как линейное)
1.2 Чем больше людей, тем более пологий график. Когда людей на рынке под 500, за 200 шагов даже не все успевают разориться
EOF

I get the error

29.05.16 22:24:09,584 QuickLookSatellite[58500]: QLStephen: Could not determine attribtues of file file:///....

if I head -1 test > test2, then can see the preview just fine.
What am I doing wrong here? How can I view the 1st file?

NB: maybe worht updating error message s/attribtues/attributes/ )

How do I get Stephen to QuickLook only file types listed in the whitelist and blacklist everything else?

Right now when I (single) click on a .sh file in the Finder, Finder tries to execute it, then crashes. I've been adding more and more file types to my QLStephenExtensionsBlackList.plist but it's tedious having to add everything.

Also I tried adding sh to the blacklist and Finder still tries to execute it the file.

As far as I can tell, this behavior is not caused by my other QuickLook plugins: BetterZipQL, QLStephen, Suspicious Package, epub, QuickLookCSV, webp,QLPrettyPatch, quicklookjson, and aa_epub.

How do I solve this?

Thank you @whomwah for your work on qlstephen! I'd like to ask you to consider adding a permissive license to the project so that new maintainers can step up and help the project without worries.

when using finder's column view, the rightmost column is usually used for a quicklook/peview for the selected file. qlstephen does not load previews for plaintext files without .txt at the end. qlstephen only adds quicklook functionality for the quicklook popup window, not the finder column view preview

Steps to reproduce:

1. Create a file with UTF-8 content. E.g. echo "füü" > bar. Verify file is encoded with UTF-8, e.g. file bar should return bar: UTF-8 Unicode text.
2. QuickLook the file. Instead of "füü" QL shows "füü".

Doesn't seem to support LESS CSS files :(

After upgrading to Mountain Lion, everytime I click on a large file (like a disk image, DMG, ISO, ZIP) on finder's column view, it starts spinning the icon and quicklookd consumes a lot of memory even causing other apps to swap to disk. After the preview icon is done, the quicklookd memory is dealocated.

This do not happen on Lion.

Removed it from /Library/Quicklook, restarted quicklook (qlmanage -r) and the problem is gone.

this is a great plugin. i hope it continues to be supported in future versions of Mac OS - i just installed it in High Sierra & it appears to be working fine.

any possibility to get it to show html files code instead of previewing it in quicklook? i love that it shows me the code for php, js, json, xml, etc; would be great to see html too.

thanks!

Like the OSX default quicklook plugin for plain text files the font is fixed to monaco 10pt. If people need larger fonts for legibility the plugin is useless. Would it be feasible to add an entry to info.plist to control the fontsize?

I've just randomly checked my activity monitor right now and your plugin seems to be the one triggering quicklookd32, a process which I don't see otherwise when running OS X Lion. Please consider doing a 64bit version.

I'd like to be able to turn off qlstephen for certain types of files, such as .savedsearch files. I don't think this is currently possible, but I'd like to request it as a feature. If it is already available, is there a guide that explains how to make use of this functionality? (I couldn't find one.)

Thanks!

For example, I'll have an SQL dump file, and when arrow-keying through a folder, it will hang-up giving me the beachball until the entire file is able to be quicklooked. It would be great if this extension ignored files over a few kb.

Is it difficult to add an option to change the font? I don't like the current font and would like it better in the Monaco, size 10, font.

Hi,

I've recently starting experiencing an issue whereby all files are previewed as text in QuickLook (even PDFs, JPGs, etc.). If I remove QLStephen from my Library, everything goes back to normal.

I cannot tell when this started, but I don't think it's always been there. Any idea if this is a bug or intended behaviour, and if the former how to debug it? Happy to share more details if needed.

Thanks

MacOSX El Capitan
QLStephen 1.4.2

In Yosemite, (never happened for me in Mavericks and before) Finder hangs when quick look tries to open .DS_Store files. I've tried adding .DS_Store to blacklist but it doesn't work. No matter if I restart computer or whatever it hangs everytime I try to quick look a .DS_Store.

I tried to install it QLStephen.qlgenerator many ways, I also tried to put the file in ~/Library/Quicklook and also in /Library/Quicklook, but does not work for me. Yes, I also tried qlmanage -r, and I tried to use only one of the Quicklook dirs at one time. It just does not work for me: if there is a file anywhere called README (or anything else, without an extension), my preview stays the original. :( I have really no idea.

After a little digging I realised that the comparison with blacklist entries appears to be case-sensitive.

Consequently I've had to add both "iso" and "ISO", "epub" and "ePub" etc. to the blacklist plist.

Right now, am not in a position to fix it myself (or I would do so and send a pull request!) but thought it was worth noting…

I have a Smart folder on the desktop, and after installing this package, the folder icon appears as a txt file (the contents are actually xml) rather than the original violet color.

QLStephen 1.2 tries to preview .dmg files, which are binary. v1.1 didn't have this problem.

Hi

I installed the plugin a while ago and everything was working fine, but now all of a sudden it isn't.
I didn't really change anything, at least not that I know of. And there was no big OS update or anything.
There also isn't any other QL plugin interfering, because if I remove all the other plugins and only keep QLStephen, it's still not working.

Is there anything you can think of, that could cause this issue? Or is there any way I can debug/troubleshoot this kind of issue?

Thanks
Steve

In my case it is not working for files such: README, AUTHORS, LICENSE - text files with no extension.

Thank you.

It would be nice if this QL Plug in was added to brew, a lot of other are added to the cask tap.
Here is a link to these.

The popular ebook formats .epub and .mobi should be added to the blacklist.

Quick Look takes a long time (10+ seconds) while trying to preview a 30 MB text file, even though the max file size parameter is set to 10 kb. Is it possible to have head file.txt behavior, which is much faster?

Not really an issue I guess, but is it possible to add borders around the icon to make it look more pleasing an inline with other QL icons? I've attached an image to illustrate what I mean. You can see that the .log file has borders to its text while the other two do not. This is because log files have native support, while the others do not.

Great plugin, btw.

Thanks for this plugin!

My suggestion is to change the wording in the readme, since it works for all of these text file extensions that don't work with QuickLook out of the box.

hi,

is it possible to preview pde files for example? It's just a text file with a pde extention.
It would be nice if people can set which extentions should be previewed as text.

The plugin seems to crash finder if the focus (selection highlighting) is on an archive type file. I've reliably tested it with ZIP's, and gzipped tarballs (tar.gz). Finder has two behaviours when crashing; one, (the most common) Finder crashes and relaunches; two, finder hangs (beachball of death).

I'm not sure what else I can do to debug. Would a log file excerpt help?

• brew info Caskroom/cask/qlstephen — does not work
• brew install Caskroom/cask/qlstephen — works, installs to /usr/local/Caskroom
• brew uninstall Caskroom/cask/qlstephen — does not work, looks in /usr/local/Cellar

Shouldn't it be brew cask install qlstephen?

macOS seems to already have an association for .ts files which is as video. I wish to have it as text, any way to do that with QLStephen?

QLstephen wasn't working so I checked:

qlmanage -d1 -p /Users/mac/.bash_history

Which returned the following error:

Deleting the Paint 2 app "solved" the issue. Can one prevent random apps interfering with the plugin?

Looks like the brew package needs to be updated:

brew install Caskroom/cask/qlstephen

Would it be possible to include Emacs org-mode files?

iCloud Drive uploads thumbnails (including those generated by QLStephen) to the cloud. That means if you store large Git repos, you end up with iCloud Drive (more precisely, revisiond and bird) constantly trying to upload 15-20 GB worth of thumbnails... My Mac was going crazy for several months and I've finally found the reason. Beware.

Thumbnail sample:

$ pwd
/Users/yegortimoshenko/Library/Application Support/CloudDocs/session/u
$ find -name thumbnail | wc -l
165546

Version 1.2 was the last to include i386 and x86_64 support in the plugin; since then only the latter has been included, preventing the plugin from running on 10.5 or 10.6 Macs with Core Solo or Core Duo processors. Is it possible to add back i386 support?

Is there any way to make this plugin only operate on certain files? I tend to only use this for README and INSTALL files (maybe just anything in all caps w/o an extension), and I'd prefer everything else to just show the default quicklook view. Especially those things that have no extension but this plugin won't view, like binary files.

DraftSight contains a QuickLook plug-in embedded in the application and with a document type "public.data".
As a result any job to be handled by QLStephen is handled by the DraftSight instead and fails, taking a lot of CPU resources. Of course this also happens without the QLStephen plug-in being present.
There seems no ideal solution, except removing the DraftSight plug-in.

Thanks for the nice plug-in, but it tries to render InDesign files which it should, because this

isn’t that helpful … theres no rendering for these files they show as an icon, but I’d prefer the icon against the messy text … is it possible to prevent you plugin from redering .indd files?

This plugin seems to be trying to show me .epub files, which of course does not work well.
