Re: Monospaced font problem
Tobia, Man, you're a genius! Your script solved the problem. I ran it and now every program (including gvim, of course) recognizes Pragmata as being monospaced.

Pablo Arantes wrote: Tony, I very much suspect you're right about it: Pragmata must be lacking the specification of being a monospaced font. Other editors besides gvim also fail to recognize the font as a valid option. Ironically, I was able to set the font as the default in Emacs accepts, but I'm afraid it's too late for a change in my religious beliefs now :-) I contacted the author of Pragmata to share my concerns but he couldn't help me much in this respect. I explained him the problem but I'm not sure he understood it. I wonder if there is a feasible way to change this specification myself. Thanks for your help, Pablo Well, I suppose there is, either by means of a font editor (I suppose such a program exists but I don't know under what name) or by binary editing (but I don't know what must be changed). Another question is of course the copyright: by editing that font in such a way, you would quite likely be infringeing the terms of the license under which you got it. Not that it would matter much as long as you don't redistribute the modified version. Best regards, Tony. -- Wethern's Law: Assumption is the mother of all screw-ups.

I want to set as the default gui font a TTF monospaced font, called Pragmata TT, but it won't show up in the list of available fonts. I've searched the vim archives and google and cannot figure out why it won't be listed as an option even though it *is* a monospaced font and other TTF monospaced fonts appear in the list. The font author could not help and provided me an OTF version that gvim accepts, although it renders much worse than the TTF in programs where the latter version actually works. Thanks in advance for any tip or suggestion. Well, maybe the code in the font itself doesn't identify it as fixed-width. Except in gvim versions with GTK2 GUI (which are for X11, thus not for native-Windows), gvim will only accept fonts that identify themselves as fixed-width. Apparently your Pragmata TT font doesn't. OTOH, Lucida Console does, although its bold Cyrillic glyphs are very slightly wider than other glyphs, which makes its use problematic when editing Russian. If ":set guifont=Pragmata_TT:h12:cDEFAULT" or ":set guifont=Pragmata:h12:cDEFAULT" don't work, then your only choice is to use another font, unless you want to compile a version of gvim for Cygwin/X11 with GTK2 GUI; but there are other problems to that.
