2015-11-17ui: improve fallback code in case of unknown termMarc André Tanner2-2/+2
If the current $TERM value indicates 256 color support fall back to xterm-256color otherwise try xterm. Improves upon 43605fded457cec954600b688d54242341eedc7c Closes #105
2015-11-14view: increase range to consider for syntax highlightingDavid B. Lamkins1-1/+1
Increase the number of bytes to consider for syntax highligthing before the visisble area. This should improve the handling of long block comments. Closes #110

Closes #109
2015-11-11ui: fall back to xterm-256color if term initialization failsMarc André Tanner1-2/+5
This improves behaviour for unknwown/unrecognized terminals as is the case for self contained binaries built with "make standalone" which only includes a fixed set of terminal descriptions. Of course the terminal capabilities won't match, which will likely cause some display issues.

When a file was being displayed in multiple windows changes in one could confuse the other.

For musl this is a nop, it contains the relevant code in libc and provides and empty libdl archive for compatibility. However certain glibc based system need it.

2015-11-08vis: factor out syntax highlighting codeMarc André Tanner3-47/+62
The view_draw function renders the text into the cells array and resyncs the cursor position. The syntax highlighting is applied in view_update, which also instructs the ui to update.

2015-11-08vis: experimental support for lua/lpeg based syntax highlightingMarc André Tanner11-48/+499
The lua based lexers are searched in the following order: $VIS_PATH/lexers $HOME/.vis/lexers /usr/share/vis/lexers followed by the standard lua package.path
2015-11-08Overhaul build systemMarc André Tanner2-6/+122
Add separate per library {C,LD}FLAGS and use default values from pkg-config to allow for finer control. Disable pkg-config by setting PKG_CONFIG_PATH= PKG_CONFIG_LIBDIR= Override flags completely by specifying them as arguments to make: $ make CFLAGS_CURSES="your custom flags for curses" Also introduce a new, experimental Makefile target standalone. It tries to build a self contained statically linked vis binary. All dependencies (musl, ncurses, termkey, lua, lpeg) are build from source. Lua is patched to include lpeg as a statically built module.
