geany: cannot open display

[shreyasjoshi15@…]

I have installed the geany using macport

#sudo port install geany

Now, when I try to launch geany from spot light. I get the following errors.

A terminal opens -

Usually one launches command-line applications like geany from a terminal window, not from Spotlight or the Finder. Running geany from a terminal window works for me. If that doesn't work for you either, what is the value of your DISPLAY environment variable? (You can run the env command to find out.)

[shreyasjoshi15@…]

This is the env

Even geany is not getting opened from terminal -

SHREYASs-MacBook-Pro:~ shreyasjoshi$ geany

Ok, so the DISPLAY environment variable is not set. Do you have an X server installed? Such as the xorg-server port, or the Xquartz package? If not, you should install it. Then close the terminal window, open a new one, and try again.

[ryandesign (Ryan Carsten Schmidt)]

Please reply in the ticket, not by email.

what will you recommend to install?

They're the same software, so the choice is just whether you would like to update it via MacPorts or a standalone installer.

[shreyasjoshi15@…]

should I use

#sudo port install xorg-server

or

#sudo port install Xquartz

Which one will you recommend?

[ryandesign (Ryan Carsten Schmidt)]

Xquartz is not a port; it's a standalone package you can download from ​http://xquartz.macosforge.org . Or if you prefer to install the same software with MacPorts, you can use "sudo port install xorg-server". I prefer installing and updating software with MacPorts so I would recommend using xorg-server.

[shreyasjoshi15@…]

I installed xorg-server. It works, but it throws error on the console. Also, I don't see the style good as compare to what I see in Linux.

SHREYASs-MacBook-Pro:~ shreyasjoshi$ /opt/local/bin/geany ; exit;

[shreyasjoshi15@…]

After installing Xorg-server. I restarted my macbook.

[ryandesign (Ryan Carsten Schmidt)]

The warnings you see in the terminal are because your LC_CTYPE environment variable is set to the invalid value UTF-8. Valid values would be any of the locales listed in the directory /usr/share/locale. Are you deliberately setting LC_CTYPE in one of your shell startup files? If so, try not doing that, and letting the terminal set things automatically. (The terminal will set the LANG environment variable to a value that corresponds to your selections in the Language & Region pane of System Preferences, and LC_CTYPE will take on the value of LANG if LC_CTYPE is not set.)

As for the "style", what do you mean exactly? Certainly X11 applications won't look as nice as native OS X applications, but the way they look should be comparable to the way they look on other operating systems that use X11.

[shreyasjoshi15@…]

No, I am not aware of any LC_Type environment. I have not done anything deliberately. Can you please suggest me the way to set the LC_CTYPE environment correctly on my macbook? The valid one.

[shreyasjoshi15@…]

I want to setup for Standard English.

[shreyasjoshi15@…]

SHREYASs-MacBook-Pro:~ shreyasjoshi$ locale
LANG=
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

[ryandesign (Ryan Carsten Schmidt)]

In System Preferences > Language & Region, have you selected English as the language and United States as the region?

In Terminal > Preferences > Profiles > Advanced, have you enabled the "Set locale and environment variables on startup" checkbox and set the "Text encoding" popup menu to "Unicode (UTF-8)"?

[shreyasjoshi15@…]

English as the language and India as the region. have you enabled the "Set locale and environment variables on startup" -> Yes. Yes, the character encoding is UTF-8 unicode.

[ryandesign (Ryan Carsten Schmidt)]

Ah, ok. Yes, OS X does not have an "en_IN.UTF-8" locale in the /usr/share/locale directory, so the automatic locale selection won't work for this combination of language and region. You could manually set the LANG environment variable to one of the locales in /usr/share/locale, for example:

export LANG=en_US.UTF-8

Do this in your shell startup file, such as ~/.profile, ~/.bash_profile, ~/.bashrc, etc.

[shreyasjoshi15@…]

I only have a ~/.profile file on my mac. I don't have bashrc and bash_profile. Is it sufficient to set only on ~./profile?

[ryandesign (Ryan Carsten Schmidt)]

Sure, set it in whichever shell startup file you use.

[shreyasjoshi15@…]

Isnt' a bug from Mac OS that they don't have bothered to have support for India and English.

[larryv (Lawrence Velázquez)]

Apple cannot provide a locale file for every possible combination of country, language, and encoding. You’re free to ​file a bug with them if you wish.

[shreyasjoshi15@…]

I guess, you can close this. It is good to support locale for India, I will say. India is the large market for computers. Also, there is a significant contribution by India in the technology. I am moved that Apple don't even bother for India, but I am sure that there are many Indians, who works for great companies like Apple, Google, and Facebook.

[larryv (Lawrence Velázquez)]

Replying to shreyasjoshi15@…:

I am moved that Apple don't even bother for India

As I already said, locales aren’t about “supporting” every combination of country, language, and encoding, as that would be an infeasible task. If you look inside /usr/share/locale, the only English locales are for Australia, Canada, Ireland, New Zealand, the United Kingdom, and the United States — probably because those are the primary countries in which English is a dominant language.

The ​comprehensive list at the Unicode Common Locale Data Repository doesn’t suggest any India/English locales either. I’m almost sure that China has more English speakers than Ireland, but there are no en_CN.* locales. And the population of Spanish speakers in the United States is almost as great as the entire population of Spain, but there are no es_US.* locales.

Did you actually get the locale to work? I’d expect that en_GB.UTF-8 would be closest to what you want.

[mf2k (Frank Schima)]

See #57151.

[mf2k (Frank Schima)]

Based on the latest reply from the reporter and the fact that I don't see what needs to change in the port, I'm closing this.

[jmroot (Joshua Root)]

There's really nothing that needs to be fixed at this point. The reporter just didn't like the warning being printed. That's just another instance of the common issues relating to LC_CTYPE=UTF-8, it being technically valid according to the standards but not really used outside of Apple systems, so a lot of software doesn't like it.
