2015-09-10Fix copy of line with len = 0Roberto E. Vargas Caballero
When a line has no any character linelen is 0, so last = &term.line[y][MIN(lastx, linelen-1)] generated a pointer to the end of the previous line. The best thing we can do in this case is to add a newline, because we don't have a glyph to print (and consult its state of wrapping).

Any system having different assignments than the usual 0, 1, 2 for the standard file numbers and 0, 1 for the exit-statuses is broken beyond repair. Let's keep it simple and just use the numbers, no reason to fall out of the window here and bend down for POSIX. In one occasion, the ret-variable was not necessary. The check was rewritten.

2015-05-25Support UTF-8 characters as word delimitersJan Christoph Ebersbach
For a higher usefulness of the utf8strchr function, the index of the UTF-8 character could be returned in addition with a Rune instead of a char*. Since utf8strchr is currently only used by ISDELIM I didn't bother to increase the complexity.

2015-05-12Small bugfix for makeglyphfontspecs call in drawregionsuigin
Here's a patch that fixes a bug when calling `makedrawglyphfontspecs' in `drawregion'. Wasn't offseting the pointer into the input glyphs array by `x1'. The bug isn't causing any problems currently, because `drawregion' is always called with `x1' and `y1' values of 0, but if this ever changes in the future, the bug would certainly cause some problems.

2015-05-07Clean up xdraws and optimize glyph drawing with non-unit kerning valuessuigin
I have another patch here for review that optimizes the performance of glyph drawing, primarily when using non-unit kerning values, and fixes a few other minor issues. It's dependent on the earlier patch from me that stores unicode codepoints in a Rune type, typedef'd to uint_least32_t. This patch is a pretty big change to xdraws so your scrutiny is appreciated. First, some performance numbers. I used Yu-Jie Lin termfps.sh shell script to benchmark before and after, and you can find it in the attachments. On my Kaveri A10 7850k machine, I get the following results: Before Patch ============ 1) Font: "Liberation Mono:pixelsize=12:antialias=false:autohint=false" cwscale: 1.0, chscale: 1.0 For 273x83 100 frames. Elapsed time : 1.553 Frames/second: 64.352 Chars /second: 1,458,159 2) Font: "Inconsolata:pixelsize=14:antialias=true:autohint=true" cwscale: 1.001, chscale: 1.001 For 239x73 100 frames. Elapsed time : 159.286 Frames/second: 0.627 Chars /second: 10,953 After Patch =========== 3) Font: "Liberation Mono:pixelsize=12:antialias=false:autohint=false" cwscale: 1.0, chscale: 1.0 For 273x83 100 frames. Elapsed time : 1.544 Frames/second: 64.728 Chars /second: 1,466,690 4) Font: "Inconsolata:pixelsize=14:antialias=true:autohint=true" cwscale: 1.001, chscale: 1.001 For 239x73 100 frames. Elapsed time : 1.955 Frames/second: 51.146 Chars /second: 892,361 As you can see, while the improvements for fonts with unit-kerning is marginal, there's a huge ~81x performance increase with the patch when using kerning values other than 1.0. So what does the patch do? The `xdraws' function would render each glyph one at a time if non-unit kerning values were configured, and this was the primary cause of the slow down. Xft provides a handful of functions which allow you to render multiple characters or glyphs at time, each with a unique <x,y> position, so it was simply a matter of massaging the data into a format that would allow us to use one of these functions. I've split `xdraws' up into two functions. In the first pass with `xmakeglyphfontspecs' it will iterate over all of the glyphs in a given row and it will build up an array of corresponding XftGlyphFontSpec records. Much of the old logic for resolving fonts for glyphs using Xft and fontconfig went into this function. The second pass is done with `xrenderglyphfontspecs' which contains the old logic for determining colors, clearing the background, and finally rendering the array of XftGlyphFontSpec records. There's a couple of other things that have been improved by this patch. For instance, the UTF-32 codepoints in the Line's were being re-encoded back into UTF-8 strings to be passed to `xdraws' which in turn would then decode back to UTF-32 to verify that the Font contained a matching glyph for the code point. Next, the UTF-8 string was being passed to `XftDrawStringUtf8' which internally mallocs a scratch buffer and decodes back to UTF-32 and does the lookup of the glyphs all over again. This patch gets rid of all of this redundant round-trip encoding and decoding of characters to be rendered and only looks up the glyph index once (per font) during the font resolution phase. So this is probably what's responsible for the marginal improvements seen when kerning values are kept to 1.0. I imagine there are other performance improvements here too, not seen in the above benchmarks, if the user has lots of non-ASCII code plane characters on the screen, or several different fonts are being utilized during screen redraw. Anyway, if you see any problems, please let me know and I can fix them.

2015-05-04Fix empty selection highlighting bug.noname
When user clicks LMB, one character is selected, but will not be copied to selection until the user moves cursor a bit. Therefore, the character should not be highlighted as selected yet. Before the patch, the trick was not to mark line as dirty to avoid highlighting it. However, if user has already selected something and clicks in line that contains selection, selclear sets the line as dirty and one character is highlighted when it should not. This patch replaces dirty trick with explicit check for sel.mode inside selected().
