Nils Reuße f2bfd513b1 keep some glyph modes for the cursor
st currently does not keep any mode for the cursor that was active
in the underlying glyph (e.g. italic text), the mode is always
ATTR_NULL [1].  At [2] you can find a screenshot that shows the
implications.  Other terminals (at least vte-based, such as
XFCE-terminal) keep some modes for the cursor.  I find the current
behaviour very disruptive, so here is a patch that keeps a few
(arbitrarily chosen) modes for the cursor.

Roberto E. Vargas Caballero 20f713548d Change default keybindings
CTRL+SHIFT is an impossible combination in the terminal world
(0x20 | x & 0x1F), so it is perfect to be used for internals
shortcuts of terminals, and being a double combination
reduces the prossibility of having comflicts.

Spencer Phippen fa9a459972 Fixed 'missing glyph doesn't use fontconfig config substitutions' bug
XftFontMatch does display-specific font configuration (commit 528241a).
Nice. Unfortunately, when we switched from FcFontMatch, we also stopped
storing the post-Fc{Config,Default}Substitute FcPattern for future
lookups. The result is that if a glyph isn't found in the primary font,
secondary font lookups use the original FcPattern, not the configured
one. If you have custom fontconfig rules (like me), this can be

I basically just copied the guts out of XftFontMatch[1] and saved
the intermediate configured FcPattern. Could be related to the bug that
inspired commit 4242027.

Manuel Tobias Schiller 740ada1447 make the various combinations of arrow keys and shift/control/meta work
When using st with screen, I've bound next, prev, new screen to
combinations like Ctrl-Alt-Right,Left,Down; xterm and (u)rxvt work fine
when this combination of modifiers is pressed, st does not seem to
transport all of them; a single modifier key is fine (e.g. Ctrl-Up,
Alt-Down etc., but combinations are not). While I'm not terribly
familiar with this, I have tried to hack config.h in a more or less
systematic way to generate the expected sequences.
2016-11-14 19:58:02 +01:00 424202798b Initial font size issue.

When I specify a font by point size (I'm using "Inconsolata:size=12"),
characters that are substituted from another font because they are not in the
main one appear too small.  Doing a zoom reset fixes it.  For example:


I found that adding the pixel size (acquired from the initial font load) to the
pattern then reloading the font fixes the problem.  I'm not sure if this is a
proper fix, though.

The two functions strdump(), csidump() are called to show errors and
their output is introduced by a message printed to stderr. Thus, it it
more consistent to have them print to stderr.

Moreover stderr is unbuffered (at least on Linux), making problems
immediately visible.

Alive 4ever 235b438e68 Consistent Alt+BackSpace behavior
The default config specifies BackSpace as "\177". The default behavior
should persist across modifier keys, commonly Mod1 (Alt or Meta) which
is widely used to delete a word on readline and text editors, notably

This will make Alt+BackSpace behaves as expected, i.e. sends "\033\177"
instead of "\033\010" as previous default behavior.

Christoph Lohmann 528241aa38 Use XftFontMatch in place of FcFontMatch.
git am -s didn't like your patch:

From: Mark Edgar <>

XftFontMatch calls XftDefaultSubstitute which configures various match
properties according to the user's configured Xft defaults (xrdb) as well as
according to the current display and screen. Most importantly, the screen DPI
is computed [1]. Without this, st uses a "default" DPI of 75 [2].

v4hn 60aeb37edb delete clipboard properties after pasting them specifies:
> Once all the data in the selection has been retrieved,
> the requestor should delete the property in the SelectionNotify request

Most Clipboard-Owners ignore whether or not the property is already set,
so this is mostly a cosmetic change to keep the windows property list clean.

However, at least synergy decides to wait for the requestor to delete
the properties if they are already set by a previous paste (from synergy).

Tor Andersson 39964614b7 st: Fix off-by-one error when calculating character width.
LEN(str) is one larger than strlen(str) because it also counts the zero
terminator. The original code would include the .notdef glyph (since it'll
try to encode character 0, which gets encoded to the .notdef glyph) when
measuring the average dimensions of printable ascii characters.

This causes problems with fonts like GNU Unifont where the .notdef glyph is
not the same width as the usual half-width characters.

ttywrite was assuming that if it could not write then it could

where you cannot read or write. The correct behaviour is to detect
if you can read or/and write.
