Idle documentation -- what to do if you do not see an underscore. #68498
Comments
On some operating systems, for instance a Macbook Pro with Retina, the Can we add this line to 25.5.5.2. and 24.6.5.2. ? It is not obvious, especially to the newbie who is trying to write their first python program that the inability to type underscores is a font problem. |
That may be a problem better fixed in Tk itself. I don't have a Retina display handy. Assuming you have a current ActiveTcl 8.5 (8.5.18) installed, could you try some of the Tk text widget demos in /usr/local/bin/wish8.5 and see if the problem shows up there, too? Not sure what the font sizes there are, though. Thanks! |
I don't have one, alas. It was a question sent to webmaster. I just |
Yes, that's probably a good thing to do in any case. I can add it to the Tcl/Tk info page for OS X as at least an interim measure: |
Thank you. I don't think that this problem is unique to Retina Macbooks -- I had it on an ancient Toshiba laptop I was using about 15 years ago. |
Sorry this issue slipped off my radar. Terry's new PR 12007 provides a more general documentation update such that the I no longer think the tcltk page should be updated. Removing myself. |
I don't think one 4-years-old anonymous report missing essential details, and not verified since, is sufficient to drive a doc change, especially since the Mac installer has switched from recommending ActiveState 8.5.18 to installing our own compilation of 8.6.8. On my MacBook Air with Mohave and 3.7.2, I added 'p__g' to the top of IDLE settings dialog font tab text sample and looked for glitches with various fonts and sizes. The only thing I found was with Optima 13. The 'g' was the double loop ('eyeglasses') form and a bit of the bottom of the lower loop was gone or thin. It was still easily recognized and the 'p__' part was unaffected. I decided to document use of the font sample, including the possibility of changing face and size to avoid glitches. Since the procedure is generic for any platform or character, I did not specify Mac or 'p_g'. |
