Fix minikin_unittests This CL fixes following test cases in minikin_tests - FontFamilyTest.hasVariationSelectorTest - HbFontCacheTest.getHbFontLockedTest - HbFontCacheTest.purgeCacheTest For the fix of FontFamilyTest.hasVariationSelectorTest, removing virtual from GetUniqueId() in MinikinFont. After [1], MinikinFont's destructor started calling purgeHbCache() which calls virtual method, MinikinFont::GetUniqueId(). Fortunately, the SkTypeface::uniqueID() returns just internal value, so we can store it at the construction time and use it instead of calling SkTypeface::uniqueID() every time. This patch also changes purgeHbFont to purgeHbFontLocked, as all uses of it were already under global mutex. This change avoids deadlock on explicit unref, as when invoked by a Java finalizer from the Java object that holds a reference to the font. Some of the tests needed to change to using the ref counting protocol rather than explicitly destructing font objects, as well.

Avoid copying of font table data The hb_font_t object holds on to tables of font data, acquired through the MinikinFont::GetTable interface, which is based on copying data into caller-owned buffers. Now that we're caching lots of hb_font_t's, the cost of these buffers is significant. This patch moves to a different interface, inspired by HarfBuzz's hb_reference_table API, where the font can provide a pointer to the actual font data (which will often be mmap'ed, so it doesn't even consume physical RAM).

Support multiple locales for font language settings. Some fonts support multiple scripts, for example, some fonts for Korean supports not only "Kore" but also "Jamo". To select fonts based on their multiple languages, this CL introduces the following changes: - Compares all languages of the font family and use the maximum score for font selection. - Even if each language of the font family doesn't support the requested language, the font get score of 2 if the requested font is covered by all of the languages of the font family. For example, the font for "ko-Hang,ko-Hani" gets score of 2 for the requested language "ko-Kore". Bug: 26687969 Change-Id: I7f13b51464c9b01982bb573251d77052b9ddbd70

Try putting combining marks in the same font run Indic combining marks, when combined with a common character such as a hyphen or a dotted circle, used to get rendered in a different font due to the greedy algorithm used in determining runs, which resulted in the base character and the combining mark getting rendered in separate font runs, resulting in a dotted circle appearing in phrases such as "100-ാം" (0031 0030 0030 002D 0D3E 0D02). This change makes combining marks change the font run of the base character if the base character is supported in the same font as the combining mark, similar to the support for emoji modifiers and the combining keycap.

Suppress line breaks in emoji + modifier An emoji base with an emoji modifier renders as a single glyph and thus should not be a line break. Current (Unicode 8) logic does indicate a line break, so we override the results of the ICU line break iterator.

Add penalty for breaks in URLs and email addresses Recent changes have added special cases for line breaks within URLs and email addresses. Such breaks are undesirable when they can be avoided, but at other times are needed to avoid huge gaps, or indeed to make the line fit at all. This patch assigns a penalty for such breaks, equal to the hyphenation penalty. The mechanism is currently very simple, but would be easy to fine-tune based on more detailed information about break quality.

Improve Paint.measureText and Paint.hasGlyph for variation sequences. Before this patch, the font fallback chain iterated all installed font families if a variation selector was specified. This CL narrows down the range of iteration. To decide the font family for the variation sequence, we need to search for both the variation sequence and its base code point. The new range of the iteration is a union of them. With this change, the running time of Paint.hasGlyph for the variation sequence improves 50% and the running time of Paint.measureText for the variation sequence improves 40% for the large text case on Nexus 6 userdebug.

Refine hyphenation around punctuation Implement a WordBreaker that defines our concept of valid word boundaries, customizing the ICU behavior. Currently, we suppress line breaks at soft hyphens (these are handled specially). Also, the new WordBreaker class has methods that determine the start and end of the word (punctuation stripped) for the purpose of hyphenation. This patch, in its current form, doesn't handle email addresses and URLs specially, but the WordBreaker class is the correct place to do so. Also, special case handling of hyphens and dashes is still done in LineBreaker, but all of that should be moved to WordBreaker.

Improve Paint.hasGlyph performance by caching hb_font_t It turned out that hb_font_t creation is not a lightweight operation. Especially, Paint.hasGlyph creates hb_font_t for all existing fonts every time. To improve the performance, cache hb_font_t instead of hb_face_t. Note that to calculate horizontal advance, MinikinPaint needs to be associated with hb_font_t by calling hb_font_set_funcs. With this patch, hb_font_set_funcs may be called multiple times for the same hb_font_t object. However this is not an issue since MinikinPaint is unique during layout.

Introduce multiple language based font fallback. The motivation of this CL is enhance the font fallback score design to support multiple language font fallback. This CL contains following changes: - Break language based font score into two: script-based score and primary-language-based score. - The primary-language-based score is 0 if the script-based score is 0. If the script-based score is not 0 and the primary language is the as same as the requested one, the font gets an extra score of 1. - The language score gets a higher multiplier for languages higher in the locale list.

Fix race condition in Paint.hasGlyph() The caller of FontFamily::hasVariationSelector needs to acquire the lock before calling it, but FontCollection::hasVariationSelector didn't acquire the lock. This caused a race condition. This CL fixes this race condition. Also, it turned out that assertMinikinLocked didn't assert even on eng or userdebug device. This CL enables assertion on eng and userdebug device since this assertion must be treated as bug. BUG: 26323806 Change-Id: I9c4b1e1f09c6793e387fbdb8bb654cc0a13c65d5

Save all kind of script tags into FontLanguage. This is 2nd attempt of I8df992a6851021903478972601a9a5c9424b100c. The main purpose of this CL is expanding FontLanguage to be able to save full script tag. Previously, FontLangauge kept only limited script tags. With this CL, FontLanguage keeps all script tags. This CL contains the following changes: - FontLanguage changes: -- Moved to private directory not to be instantiated outside of Minikin. -- Removed bool(), bits(), FontLanguage(uint32_t) methods which are no longer used. -- Change the FontLanguage internal data structure. -- Introduces script match logic. - FontLanguages changes: -- Moved to private directory not to be instantiated outside of Minikin. -- This is now std::vector<FontLanguage> - FontLanguageListCache changes: -- Now FontLanguageListCache::getId through FontStyle::registerLanguageList is the only way to instantiate the FontLanguage. -- Normalize input to be BCP47 compliant identifier by ICU.

Search all families instead of using mRanges for variation sequence. To optimize the font family search, mRanges is used for narrowing down the search range. However, mRanges is constructed from format 4 or format 12 entries. So, if the font supports a variation sequence but doesn't support the base character of the sequence, the font may not be listed in mRanges. The proper way to fix this issue is using format 14 subtable information for mRanges construction. However, this is not a trivial work since currently we rely on HarfBuzz for variation sequence lookup and it doesn't provide any API for retrieving coverage information. Thus, as the quick fix, iterate all font families in font fallback chain if the variation sequence is specified. Change-Id: I278da84be8fb8f553590e2e42ed450b7e4a34eca

Resolve glyph ID by HarfBuzz function. Currently codepoint to glyph ID resolution is done through MinikinFont interface. To support variation selector, use HarfBuzz API instead of calling this interface since one of its implementation Skia doesn't support variation selector. On the other hand, we don't want to get glyph horizontal advance values by HarfBuzz since HarfBuzz doesn't return correct values when the hinting is active. Thus, use ot_font as a parent font and override glyph_h_advance/glyph_h_origin functions as is. With this change, MinikinFont::GetGlyph is no longer necessary but not removing in this CL for easy reverting since removing interface requires multi-repository commit. This is a base work of b/11256006 and this patch doesn't provide any user visible changes. Bug: 11256006 Change-Id: I061172c0b674bb649ce8bc013ffecf38708bdc41

Improve fallback where explicit variant is not given In computing scores for which fallback font to choose, a match of a variant given explicitly in the xml config file scores higher than a family with no explicit variant. One consequence is that U+2010 HYPHEN is chosen from the Naskh Arabic font in the fallback case. This patch scores families with no variants as a match (effectively the same as if the xml file specified both variants). Thus, it will choose the first matching font (Roboto), which is a better choice. This patch also revises the list of "sticky" characters to include various hyphens, so Arabic (and potentially other scripts) text that includes hyphens can access the script-specific variants matched to the underlying text.

Consistently apply break opportunities in text spans It's essential not to apply a break opportunity within a replacement span, otherwise things can happen such as displaying the span twice. The old code tested this case based on zero-width characters. However, this test was both imprecise, and also in some cases read uninitialized values from the mCharWidths array, which in turn led to inconsistent line breaking of the same text. This patch applies all line break opportunities (as identified by ICU) within text (as opposed to replacement spans), and also applies break opportunities at the beginning and end of replacement spans, but avoids breaks within a replacement span.

Allow clusters to start with zero-width characters The logic in getRunAdvance() assumed that any zero-width character was part of the preceding cluster, which is valid most of the time.

Separate additional penalty for last line with hyphen A recent change added a penalty for a hyphen at the last line break, which is visually undesirable.

Use ASCII HYPHEN-MINUS when there's no HYPHEN in the font. Previously, we just assumed the font in use had a U+2010 HYPHEN character, resulting in a tofu (or an empty space) being shown when U+2010 was not supported in the font used to render the hyphenated word. Now we try to fallback to U+002D HYPHEN-MINUS, which has a very good chance of being available in at least any Latin font. We still show a tofu when neither character is supported, to intentionally alert that something is missing.

As a result, wrong index could be used in getRunAdvance. Bug: 21744454 Change-Id: Ibe83cc50ed6f0da2a1532318bc224502be350699

Increase hyphenation penalty for short last line Tuning for hyphenation parameters. We discourage hyphenation on the last line, but offset this penalty by also applying a penalty for each line, which optimizes for minimizing the number of lines. Thus, when hyphenation can reduce the number of lines, it increases the chance they're used. There's probably more tuning and refinement that can be done, but testing suggests that the tunable parameters are appropriate. Bug: 20883322 Change-Id: Ida7eaf8aced109e426694f5a386924a842d29c4b

Don't include trailing newline in width for line breaking In a paragraph with a trailing newline, the width of the newline character was included in the line width for breaking purposes, basically as if it were a non-breaking space. This caused a discrepancy, where Layout.getDesiredWidth() suggested that the text would fit in a single line, but StaticLayout would break it because of the added width of the newline character. The proposed fix is simply to consider newline to be a space that disappears at the end of a line. Bug: 20152308 Change-Id: I539574c5b8ea892c8ed6aca6c59e90ccdf74a680

Add hyphenation to line breaking This patch adds hyphenation using the Liang hyphenation algorithm, similar to TeX. It also improves the optimized line breaker so that it works correctly and efficiently even when the line width is not constant (there is a specialization for constant width, which is probably worthwhile, but performance TODOs remain). Still to be done: * hyphenator has many shortcuts, only tested with English * interaction between punctuation and hyphenation is problematic Change-Id: I2d94a1668ebc536398b7c43fcf486333eeb7c6aa

Add LineBreaker to Minikin This patch adds a LineBreaker class to Minikin, which will be used for computing line breaks in StaticLayout. The version in this patch contains basically the same functionality that existed before, but hopefully better performance and an interface that's suitable for more sophisticated paragraph layout. Note that this version contains a high quality strategy, which mostly works but doesn't respect varying line width. Change-Id: I02485d58b1e52856296a72cdd4efd963bc572933

Fix Layout initialization in the skipCache path C++ local var initialization always tricks me. Previously, Layout didn't have a constructor, which meant that defining it on the stack left mAdvance uninitialized. This was not an issue when we were doing "new Layout()", since that invokes zero-initialization, but was an issue for the skipCache path that was allocating layout on stack by just "Layout l" instead of "Layout l = Layout()". To avoid surprises, add a constructors that clears everything. Also adds reset() method to reset the layout for reuse. Change-Id: I3e02f00da9dd7d360abe13f63c310f6882292d0a

Choose same font for Emoji keycap and its base character The U+20E3 COMBINING KEYCAP is used in our fonts to generate an emoji rendering of ASCII numbers and letters through GSUB. For that to work we need to choose the same (Emoji) font for the character coming *before* the COMBINING KEYCAP character. This is a special-case of a broader need to choose fonts per grapheme cluster as opposed to per character, but for now, special-case U+20E3.

Assign non-coverage font runs to base font When a run has no cmap coverage in any font, use the base font. Most of the time, this will cause rendering of the .notdef glyph, which is preferable to displaying nothing. In some cases, Harfbuzz may be able to decompose the characters (not in the cmap) to ones that are, in which case we'll render those, as long as they're in the base font.

Make font runs less sticky Fixes b/15734816 In the text "Wi-Fi", "-Fi" appears bolder than "Wi" The problem was caused by "stickiness" in choosing fonts, where layout would prefer using a font used for preceding characters as long as it mapped the following characters in a run, in favor of the "best match" rules. This patch adds a whitelist for making the stickiness more conservative, only applying it for characters necessary for correct shaping (ZWJ and ZWNJ in particular) and basic punctuation, where it is desirable to match the style of the preceding text.

Caching for layouts and harfbuzz faces This patch adds caching for both layouts and for HarfBuzz face objects. The granularity of the cache for layouts is words, so it splits the input string at word boundaries (using a heuristic). There are is also some refactoring to reduce the amount of allocation and copying, and movement towards properly supporting contexts. The size of the caches is a fixed number of entries; thus, it is possible to consume a large amount of memory by filling the cache with lots of large strings. This should be refined towards a scheme that bounds the total memory used by the cache. This patch fixes bug 15237293 "Regression: Measure performance is significantly slower with minikin".

Do BiDi algorithm for text layout This is a fix for bug 15130102 "Language name for Hebrew displayed the wrong way around on keyboard". This patch extends the previous BiDi support (when the direction for the entire string was given by the caller) to run the BiDi algorithm (provided by ICU) over the string to break it into BiDi runs. Thus, it handles mixed LTR and RTL strings in a single layout, and also respects heuristics for inferring the paragraph direction from the string.

Initial BiDi support This patch contains a very basic implementation of BiDi. It respects the BiDi flags passed in as an explicit parameter (through the "-minikin-bidi" pseudo-CSS property), but doesn't yet do its own BiDi run detection. It also takes some shortcuts (marked as TODO) that are based on reasonable assumptions of the current font stack, but not universally valid. Even with these shortcomings, it seems to display RTL text from TextView correctly. Change-Id: I223433923c4eb06f90c0327e86bfbe0aff71d4f5

A basket of features: itemization, bounds, refcount This patch improves script run itemization and also exposes metrics and bounds for layouts. In addition, there is a fair amount of internal cleanup, including ref counting, and making the MinikinFont abstraction strong enough to support both FreeType and Skia implementations. There is also a sample implementation using Skia, in the sample directory. As part of its functionality, his patch measures the bounds of the layout and gives access through Layout::GetBounds(). The corresponding method is not implemented in the FreeType-only implementation of MinikinFont, so that will probably have to be fixed. Change-Id: Ib1a3fe9d7c90519ac651fb4aa957848e4bb758ec

Initial commit of Minikin library This is the initial draft of Minikin, a library intended to perform text layout functions. This version does basic weight selection and font runs for scripts, and also has a simple renderer for drawing into bitmaps, but is lacking measurement, line breaking, and a number of other important features. It also lacks caching and other performance refinements. Change-Id: I789a2e47d11d71202dc84b4751b51a5e2cd9c451
