[Pharo-project] News about bundling VM (Mac users mostly)
by Igor Stasenko June 21, 2012

June 21, 2012

Hi, there i spent whole day with Esteban, testing & fixing new CMake configuration on Jenkins, to integrate the changes i made for bundling VM with 3-rd party libraries ( see [1] ). We finally made it working, as you can see in hot-backed build here: https://ci.lille.inria.fr/pharo/job/Cog-Mac-Cocoa-Esteban/72/ So, in a few days we will update the blessed branch to also use new cmake configuration(s). (right now the jobs at [2],[3] still using old configs) Some details about changes: - changed the FT2Plugin to link dynamically with freetype library on Mac, instead of statically - changed the VM bundle directory layout: now all external plugins and dlls are stored in Contents/Plugins subdir, instead of Contents/Resources as before (see screenshot attached) - changed the external plugin search logic to search this Plugins dir instead of Resources - by default, all Mac VM's will be bundled with own version of Freetype dynamic library, - also , i will bundle NBCog VMs with cairo library by default (so, no extra installation is required) If you want to reproduce build by own, note that on OSX 10.6. tar does not supports 7z compression, you should install it: port install gnutar port install xz ln -s /opt/local/bin/gnutar /opt/local/bin/tar (and make sure that /opt/local/bin is first in your PATH variable) On Lion (10.7) no extra effort is required.

Re: [Pharo-project] Worskpace question

I don't think its related to the processes priority. Can you provide more code of the DrGeoCanvas>>#initialize ? Because, the following works just fine, by evaluating the first two lines, or the complete script. m := Morph new. m openInWorld. m color: Color red. m extent: 300@300. m delete Fernando On Wed, Jun 20, 2012 at 12:16 PM, Hilaire Fer nandes <hilaire.fernandes(a)edu.ge.ch> wrote: > DHello, > > I have a question regarding the Workspace when you execute code from there. > > Let me show with an example: > > I want to execute code instantiating an empty DrGeo sketch (a morph) > then create programmatically content: > > > |canvas| > canvas := DrGeoCanvas new. > canvas segment: 5@4 to: 10@20. > canvas vector: 0@0 to: 2@2. > ... > > The line with DrGeoCanavas creates and opens a new morph of a DrGeo sketch. > > My problem is: the morph only shows up on screen when the whole > Workspace code is executed.

[Pharo-project] Fastest utf-8 encoder contest
by Igor Stasenko June 21, 2012

June 21, 2012

Hi, hardcore hackers. please take a look at the code and tell if it can be improved. The AsmJit snippet below transforms an unicode integer value to 1..4-byte sequence of utf-8 then the outer piece of code (which is not yet written) will accumulate the results of this snippet to do a memory-aligned (4byte) writes.. like that, if 4 unicode characters can be encoded into 4 utf-8 bytes (which mostly the case for latin-1 char range), then there will be 4 memory reads (to read four 32-bit unicode values) but only single memory write (to write four 8-bit utf-8 encoded values). The idea is to make utf-8 encoding speed close to memory copying speed :) convertUnicode: asm " input: - EAX 32-bit unicode value to convert output: - EAX - utf-8 encoded character (in little-endian byte order) max 4 bytes - EDX - number of encoded bytes " | moreThanOne moreThanTwo moreThanThree end | moreThanOne := asm uniqueLabelName: 'moreThanOne'. moreThanTwo := asm uniqueLabelName: 'moreThanTwo'. moreThanThree := asm uniqueLabelName: 'moreThanThree'. end := asm uniqueLabelName: 'end'. asm cmp: asm EAX with: 16r7F; jg: moreThanOne; "one byte" mov: 1 to: asm EDX; jmp: end; label: moreThanOne; cmp: asm EAX with: 16r7FF; jg: moreThanTwo; "two bytes 80 .. 7FF" " AH AL " "00000aaa aabbbbbb" "110aaaaa 10bbbbbb AL AH (little endian order) " shr: asm EAX with: 2; shl: asm AL with: 2; or: asm AX with: 2r1100000010000000; xchg: asm AL with: asm AH; mov: 2 to: asm EDX; jmp: end; label: moreThanTwo; cmp: asm EAX with: 16rFFFF; jg: moreThanThree; "three bytes 800 ...
