If the size of the terminal emulator changes, the application should update accordingly.
When i run
autoreconf -i
./configure && make && make install
I get this error:
./configure: line 4631: syntax error near unexpected token `dash-version'
./configure: line 4631: `AX_IS_RELEASE(dash-version)'
Right now, source-encoded (i.e. UTF-8) pipe characters are written directly to the terminal without any character encoding. If the user's terminal uses an encoding other than UTF-8, this will fail in more or less interesting ways. A more robust approach would be to use iconv
to correctly generate characters in the users's locale.

The %SED error goes away when I replace the % with a $ in configure, but there's something wrong with the iconv error, as I've got iconv, libiconv, and libiconv-static installed. Build environment is Termux.
This is in a git branch because I extracted the release into my repo, autoconf-archive is unavailable in termux, so I can't generate the config myself anyways.
Right know, if I'm not mistaken, only Ctrl+C can normally exit Snakes.
It would be nice that we can press any key to quit.
@OneLastTry maybe we should split them, create another repository for snakes.pl
?
Remove snakes.pl
from commits and forced update, and extract it and LICENSE
for its own repository. Since currently we have no GitHub forks, it could be a good time to do it if we want to.
Do you think this is a good idea?
If you think so, I'd hope you'd take on this, and take the chance to update README
after the extraction completed.
To ensure any PR can be compiled without issues.
Few notes:
-Werror
, so the build would fail on a single warning.CC=clang
.pkg-config
and I don't know how that will go on Mac.Thoughts and takers, if @StefansM approves this.
Hello, I'm getting a problem while compiling:
gcc (GCC) 8.2.1 20180831
src/cpipes.c:135:5: エラー: ‘strncpy’ specified bound 66 equals destination size [-Werror=stringop-truncation]
strncpy(inbuf, selected_chars, CHAR_BUF_SZ);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~```
I would recommend making inbuf (and utf8buf) larger by 1 so you definitely get the null terminator in there.
At the moment, we use COLORS
(i.e. the max available) colours, but don't actually initialise any to anything beyond the default values. We should take advantage of all available colours (the max. number of colours should be configurable). An HSL to RGB converter will let us pick colours that look good on a dark (or light) background and span the colours nicely.
Following from that, the background colour for the pipes should be configurable and default to the colour used by terminal (i.e. call the ncurses extension use_default_colors
and default passing -1
to init_pair
). If the background is dark, the default pipe colours should be light and vice-versa.
The #3 makes me think about the installed binary, snake
might conflict with others, a search with "snake" on Portage File List (an installed files search engine for Gentoo Portage) showed two potential conflicts:
dev-lang/nwcc
: /usr/nwcc/bin/snake
games-misc/bsd-games
: /usr/games/bin/snake
Never heard of nwcc, but bsd-games is enough. Another quick search for "snakes" returned zero results. It is not a filepath conflict, but PATH
search issue.
And if we are going to submit this to package directory, this would have to be fixed, even this might be allowed as long as no one else is installed at /usr/bin/snake
, although we might need to install under /usr/games
depending on the rules of the directory.
I can see a few solutions:
