grow selection from point of click, not start of selection region.
starting at the beginning of the selection region causes the match
logic to kick in, which is confusing.
the caller of macexpand() needs one more byte in
the buffer to append peekc.
make macexpand() actually check for buffer overflow.
just use strdup() to duplicate include file name
instead of the hunk dance.
move GETC() macro in cc.h
looks like linux changed the device tree names for
the memory node:
4b17654f51 (diff-ac03c9402b807c11d42edc9e8d03dfc7)
this fixes the memory size detection with latest firmware
on raspberry pi4-b (4GB) for kenji.
with scroll-wheel scrolling, this case can happen with the
command window:
umbraticus → cinap: create fullscreen file buffer by right-clicking in cmd window
slookup() copies to symb, so use the symb[NSYMB] buffer directly
to declare type conversion functions and get rid of the arbitrary
sized local buffer. replace sprint() with snprint().
We used to treat all operators as right associative,
which means that we would evaluate them incorrecty.
For example, '2 - 1 + 1' would evaluate as '2 - (1 + 2)',
instead of '(2 - 1) + 1'.
This adds an assoc parameter to struct pri, and then uses
it to decide how to evaluate operators.
when pushing expressions in cpp, particularly complex ones could
overflow the stack and silently corrupt our data structures. add
checks when we push, and bump the stack size up.
for floating point operations, reuse the return register
on the right hand side if it has higher complex number
than the left hand side to conserve registers.
this makes the following code compile, that was previously
run out of floating point register:
float
f(float r[15])
{
return (r[0] + (r[1] * (r[2] + r[3] * (r[4] + r[5] * (r[6] + r[7] * (r[8] + r[9] * (r[10] + r[11] * (r[12] + r[13] * r[14]))))))));
}
the downside is that this produces extra move operations.
BurnZeZ reported this the other day. It seems like if we have
a pipeline that looks like:
fn foo{cat < <{echo hi}}
then the '<' will get merged in /env/'fn#foo'. This change
fixes pcmd to add a space. It looks to me like this is the
only token that can get merged this way by pcmd.
The previous patch to plumb non-whitespace segments was
confusing due to lack of visual feedback. This removes
the empty selecton plumb behavior, and instead makes
triple clicking work to get a plumbable selection.
when running ndb configuration, we might inherit the ipgw=
attribute from the ipnet pointing to our own ip address
(we are the default gateway). ignore such entries.
do not add default routes with gateway equal to our own
local (ip4) or link-local ip address (ipv6).
