The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

Stupid GitHub tricks

All that work parsing git repositories was for naught—it seems you can link to individual files on GitHub (go figure!). So now I can create a rockspec per module, like:

package = "org.conman.tcc"
version = "1.0.0-0"

source =
{
  url = "https://raw.github.com/spc476/lua-conmanorg/1.0.0/src/tcc.c"
}

description =
{
  homepage = "http://...",
  maintainer = "Sean Conner <sean@conman.org>",
  license    = "LGPL",
  summary    = "Lua wrapper for TCC",
  detailed   = [[
	Blah blah blah
  ]]
}

dependencies =
{
  "lua ~> 5.1"
}

external_dependencies =
{
  TCC = { header = "libtcc.h" }
}

build =
{
  type = "builtin",
  copy_directories = {},
  modules =
  {
    ['org.conman.tcc'] = 
    {
      sources   = { 'tcc.c' },
      libraries = { "tcc" },
    }
  },

  variables =
  {
    CC = "$(CC) -std=c99",
    CFLAGS = "$(CFLAGS)",
    LFLAGS = "$(LIBFLAG)",
    LUALIB = "$(LIBDIR)"
  }
}

(this particular module embeds a C compiler in Lua, which is something I do need to talk about).

But it isn't like I wasted time on this. No, I don't view it that way at all. In fact, I learned a few things—how to parse git repositories, how to parse a variable amount of data in LPeg and I have code to extract a single file into its own git repository if I ever have that need again.

Obligatory AI Disclaimer

No AI was used in the making of this site, unless otherwise noted.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

https://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
