[HarfBuzz] Clang warnings while compiling HB trunk
Hello. I'm running Clang 3.2 on Kubuntu Saucy. My HB Git clone is up-to-date as of the present instant. Since I forgot to install build-essential, GCC (4.8.1) is currently NOT installed on my Saucy system. Hence the HB build system detected Clang and compiled using it and I came across some warnings which I don't remember getting when compiling using GCC. I remember reading that Clang is more stringent about language grammar than GCC so I am reproducing the shell transcript so the devels can look into those and possibly fix any hiding bugs. On the terminal I get it in colour so it's too bad I can't copy-paste that into the text file!

Hello people. I just made a quick PyQt4 app to help testing latest HB's rendering of given text. I think it should be straightforward to use.

Re: [HarfBuzz] dotted circle is not appearing for dependant vowel
On Tue, Jul 24, 2012 at 3:26 PM, Pravin Satpute psatp...@redhat.com wrote: I see the dotted circle is still not appearing with dependant vowels (U+093f), Is this intentionally? Might be since you are removing test cases generating dotted circle in Uniscribe before running it with harfbuzz. May I take this opportunity to record what I have long felt on the topic of dotted circles. I feel that dotted circles should not be displayed except when not doing so can cause non-canonically-equivalent encoded sequences to appear the same. That is, they should be displayed only to distinguish between such sequences. (This is to protect against phishing and such.) For example, the long vowel आ does not have a decomposition to अ+ ा whereas it would appear the same as the latter if there is no dotted circle. There are many such do not use recommendations for independent vowels in the Indic Unicode chapters because of the absences of canonical equivalences (unfortunate IMO but well). Reordrant vowels like ि are also likewise, because in the case of a sequence अिक mistakenly typed (or maliciously introduced) for अकि if there is no dotted circle the two sequences would appear the same which is not appropriate from a security viewpoint as they are not canonically equivalent. My point is, there may be many reasons for unexpected combinations of characters in Indic. Vedic texts is one. Minority orthographies is (which may use rare combinations of vowel signs and diacritics) another. Legitimate creative use (like काा) for k (a shout) is yet another. Imposing a limited orthography (i.e. only recognizing a certain set of patterns of sequences and producing dotted circles for sequences that do not fit the pattern) would preclude the usefulness of the rendering system to users of such cases. Of course, this usability can also be achieved by first imposing a generic orthography (i.e. script grammar) and later adding more recognized sequences as per user community request. (This is also much easier to produce and deliver to the community in open source ecosystems than in proprietary ones.) This would be advisable since it may be difficult to predict which sequences in Indic would be confusable, especially with non-spacing marks. For example, तु and तुु would be confusable if there is no dotted circle and the second ु is overlaid upon the first. But these sequences are not self-obvious, so it appears creating regexs for sequences where dotted circles should *not* be produced might be easier than to do so where they *should* be produced and it would be appropriate to err on the side of caution. I had to say this, being a scholar of Sanskrit and Vedic, which really puts scripts (and hence software support for them) to their limit.

Hi -- while I note your words within parans, I wonder why you have chosen Uniscribe as the standard? Is it simply because it is widely deployed? Despite MS's QA, there *might* be problems in Uniscribe's rendering (I don't use Windows 7 so I'm not sure about its rendering) -- in which case would the bug have to be fixed in Uniscribe first before it can be done for HB? (Mind you, I'm just wondering here, since I haven't actually run into such a sequence...) Jonathan, this is what's happening: Both Rachana and Raghu have 'half' lookups that subtitute C,H sequences with glyphs that are essentially ligatures of explicit halant on the consonant (not half forms really, from what I can see). As such, our L-matra repositioning logic positions matras to the left of such glyphs. In other words, since there is no explicit Halant glyph, matra is not repositioned. This is exactly what the spec says, and works for Devanagari. But Uniscribe seems to move it anyway. Is it the case that Malayalam does not have half forms? If that is the case, that would explain, and we can adjust this. What other scripts do not have half forms BTW? FWIW, if by half forms you mean C1-conjoining forms (where in a cluster C1 + Virama + C2, C2 remains as is and only C1 changes), Malayalam does not have those. Previously the chillu-s (see the fag end of the Malayalam code chart) were analysed as such, but no longer since they were separately encoded. The dot reph is also functionally a C1-conjoining form (in that it indicates a cluster-initial consonant) but it is also encoded separately. So basically Malayalam Unicode does not have any sequences C + Virama that map to a conjoining form when followed by a consonant. So it boils down to: if a Malayalam font is still providing mappings for C + Virama (+ ZWJ) to chillu forms then it is not compliant with current Unicode recommendations and should be fixed. Have you tested with Lohit Malayalam? (As for other scripts, Tamil also doesn't have any half-forms, but you know that already.)

So I recommend to stick to syllabic. Or if you want: abugida, which is *the* recognized term for this kind of scripts.

I heard even sometimes Arabic uses diacritics on consonants to indicate vowels a la abugidas. Perhaps southasian might be OK as I think the scripts under question here are the same as those Unicode classifies under South Asian and South East Asian at http://www.unicode.org/charts/. South East Asian could be subsumed under South Asian, I think that should not be a problem. Just asian would include Han etc too which I guess is not right. So asiansyllabic would exclude the ideographic/logographic scripts and restrict to the abugidas. Either asiansyllabic, or syllabic if Arabic is not considered syllabic, would do. BTW where does Hebrew go in?

Cursor movement should work according to the UAX#29. OK fine, but still the Tamil issue applies, as the above standard reads: Indic scripts vary considerably in how they handle the rendering of such aksaras—in some cases stacking them up into combined forms known as consonant conjuncts, and in other cases stringing them out horizontally, with visible renditions of the halant on each consonant in the sequence. There is even greater variability in how the typical liquid consonants (or medials), ya, ra, la, and wa, are handled for display in combinations in aksaras. So tailorings for aksaras may need to be script-, language-, font-, or context-specific to be useful. stringing out horizontally with visible renditions of the halant on each consonant in the sequence applies to Tamil. Hence tailoring is necessary. -- Shriramana Sharma ___ HarfBuzz mailing list HarfBuzz@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/harfbuzz

[HarfBuzz] (noob?) Building HB
Sorry for this query which is probably highly noob-y, but I encountered a problem in building HB (for the first time). Pravin Satpute advised me on the following: 1) git clone http://cgit.freedesktop.org/harfbuzz/ 2) compile it 3) use hb-view for testing but for some reason I had to replace http:// by git:// and anyhow I now have the source tree. I don't know how to compile it in place without messing up the contents of the source tree so I just did a plain vanilla cp -R of the harfbuzz directory to elsewhere and did ./autogen.sh (which is the only executable in the root). It told me to install autoreconf so I did apt-get install autoconf. It then threw an error Can't exec libtoolize so I did apt-get install libtool.

That doesn't sound right. The backspace should erase the last character that was input. Rendering engines should only take care of rendering whatever sequence of characters has been input and not change the sequence of characters right? I believe what Behdad means is: for decomposition: if HB is faced with the task of rendering U+0958 but the font doesn't provide that glyph, then should HB try to decompose it to U+0915 and U+093C and render the sequence? for composition: (I'm not too sure about *this* one but) if HB has to render a decomposed sequence which has an equivalent precomposed character, should HB try to lookup the glyph for that precomposed character (as it may give proper placement of diacritic etc)? I vote YES on both accounts.
