Discount

Downloads

To build discount, untar your selected tarball, cd into the directory it creates, then do configure.sh to generate your Makefiles. After doing this, a make should give you a functional stack of programs and libraries.

Discount builds, for me, on MacOS 10.14, MacOS 13.7, FreeBSD 4.8, NetBSD 8, NetBSD 11 Minix 3, Debian Linux 2.2, and a pile of more-modern Linuxes on ia64 & arm processors It may build on SLS Linux and Windows with mingw, but I’m not sure about that.

• Version 3.0.1.2

  There was a decade-old bug in my paranoid malloc where I was using acalloc to grab the raw data buffer for amalloc, thus initializing it to null and hiding a bunch of places where I wasn’t null-terminating a string.

  3.0.1.2 corrects that, and adds a new #define – COMPLETE(x), which adds a null terminator to a Cstring – that I’m using to explicitly null terminate strings instead of EXPAND(s) = 0; S(s)--;, which is enough extra code so I might forget it.

• Version 3.0.1.1

  And of course there were a bunch of new strings that I forgot to terminate in version 3.0.1 …

  3.0.1.1 corrects that defect. Sigh.

• Version 3.0.1

  Whew, where do I begin?

  • I ran out of slots in the original bitmap flags structure, so I dumped it and replaced it with a new flag blob accessed through a flag pointer. This broke the entire published interface and required the update to version 3 (this is why it took me over 3 years to implement it; I needed to test the code to within an inch of it’s life and between that and transitioning it just ate up time like you wouldn’t believe!)
  • Because I changed the mkd_flag_t structure and replaced it with a blob, the old flags are now a pointer and using the mkd_flag_isset(), mkd_set_flag(), and mkd_clr_flag() functions I introduced during the end of the run for version 2.x.x is now mandatory unless you’re fond of core dumps.
  • The way I’d originally implemented HTML5 (if that’s even a thing anymore?) support was to have a global structure that I allocated once and then you were stuck with it forever (and had to deallocate the structure whenever you stopped using the library otherwise it would leak memory), so I fixed that for v3.0.0 by moving the html5 details inside the MMIOT (activated by setting the flag MKD_HTML5) so it will automatically be deallocated when you are done with a document without affecting other MMIOTs.
  • Github user mwfont-csl suggested (and provided a patch – which, alas, I couldn’t use because github doesn’t seem to have a way to export patches by themselves?) adding support for fractional sizes on images as well as pixels sizes (so, 40%×40% instead of 40x40 pixesl), which I worked into the code using mwfong-csl’s original code as a reference.
  • mwfong-csl also provided a patch to do extended attributes on links and image links, via putting those attributes into a {...} bracketed block immediately after the link. As before, I couldn’t figure out a way to export just a patch from github, so I worked it into the code using their original code as a reference.
  • Annoyingly, netbsd11, broke the implementation of isspace() by putting in a version that dumped core if the input character was outside the ranges of EOF or 0x00..0xff (I deliberately use the word broken because it broke the principle of least surprise, which either nobody cares about or is trying maliciously to stop people from using C anymore.) Fortunately could patch around this misbehavior by detecting it in configure.sh and telling the compiler (clang and gcc; dunno about other compilers) to make the default character unsigned.
  • There are also a few of memory leaks remaining, and I fixed a couple of them before this release..

Version 2,x.x releases are still available and can be found in the archives.
