Specify Color by Line

Color

This is one of the core features that will be introduced in v0.3. My current idea for this feature is as follows:

1. User adds a tag on the line that they want colored (for example {COLOR_BLUE})
2. Dss will detect the color code and assign it to a value in the struct. the line will be stored without the tag.
3. when printing lines to the screen, if dss encounters a different color, it'll print that line in that color, then the next line will be in the original color.

This is a very basic overview but hopefully it gets the idea across.

Okay so I've made some changes to how the colors work. Here is a short list of some of the more significant commits/changes:

• commit f26d88e256b14579b39334df43fea847d03e8d55 adds 56 unique color pairs (64 - 8 that are same fg/bg), t cycles the foreground colors and T cycles background colors.
• commits cbe9fd7e81a629e26cdac4158bc5cf274c1d4800 and 176bf5a7b6e34a921f04e0801f31d89e8d141efa parse each line for a color tag, this color tag is set to the colorPair value of that line. When printing that line, dss switches to that color pair, prints, and then switches back

There is still a lot of work to do. Here is a list of changes that still need to be made:

• currently the tag to set a color is COLOR="n" where n is the numerical value to be set. Is there a better tag that we could use here?
• tag removal logic is dependent on tag being at the end of line (solved by commit 9a911431d70edd6da5550506f467c100664e3f57), and < 9 and (solved by commit 2818b6de9980116e0b269a664027992adefd129a)
• coloring works best if the line's background color is the same as the global background color. annoyingly if a user wants to use a different color background than black they'd need to set it manually upon start up every time. can we designate a default global color in the text file? how about a color by slide to allow even more freedom?

commit a51648eedf77a0ad27dd0c8792697c39d3af8cb9 adds some basic error handling for color tags. if a tag is >= 1 or <= 56 then it'll be parsed normally, otherwise an error message will print (with the slide number and line number), and the tag will be left in the line. This is a soft error, so after a key is pressed the slides will be loaded.

Commit 9a911431d70edd6da5550506f467c100664e3f57 is a feature complete implementation of line coloring (select one of 56 color pairs, tag is removed after parsing, error handling implemented), so with this commit added I'm going to close this issue. Other features noted in the comments above that weren't solved by this or previous commits will be have their own separate issue.
