Hi Stepharo, Thanks very much for your feedback.

I've also realised that I built all my changes on an older version of Tabular. :-( So, time to learn more about Monticello... Reading the Updated PbE is helpful, however I did notice one thing which doesn't match my experience. On page 150 it is discussing how you can't lose code... "This is because all of the code that you executed is saved in the .changes file. All of it! This includes one liners that you evaluate in a workspace, as well as code that you add to a class while programming." Should "workspace" be changed to "playground"? My experience has been that code evaluated in the playground is *not* saved to the changes file (Pharo 4.0 and 5.0). Is there a way to tell Pharo to save evaluated code to the changes file? (I admit to being lazy and not trying to figure this one out myself yet). Finally, in Section 8.2 on versions of a method, my impression from reading the section was that it would always display all versions of a method, i.e. I have 24 versions of a package in my package cache, so expected to see each modification to each method in the package. However because I had switched to a new image and loaded the newest package, only the latest version was shown. Re-reading the section, it does say that you can see each version that you save, however it might be worthwhile adding a sentence that explicitly states that only versions loaded into the image are shown (I guess it is actually versions in the changes file?). Thanks again, Alistair # vim: tw=72

yes it is. but you can create an FFI function to http://linux.die.net/man/2/readlink to get that :) Esteban > On 20 Apr 2016, at 18:11, Damien Cassou <Damien.Cassou(a)inria.fr> wrote: > > Esteban Lorenzano <estebanlm(a)gmail.com> writes: > >> it has it. >> this is how is done in mac: >> >> *isSymlink = [[fileAttributes objectForKey: NSFileType] isEqualToString: NSFileTypeSymbolicLink] ? 1 : 0; >> >> and this how is done in linux: >> >> stat(unixPath, &statBuf) && lstat(unixPath, &statBuf) >> ... >> *isSymlink = S_ISLNK(statBuf.st_mode); >> >> â¦ and in windows is always false. > > ok for isSymlink, but how do you get to the file pointed to by the > symlink?

ensureCreateFile

by Valentin Ryckewaert

Hi, I would like to have your opinion about what you want ensureCreateFile to do. According to me ensureCreateFile should do the same thing as ensureCreateDirectory + create the file in the last directory given but in its implementation if the parents of this file doesn't exist we get an Exception. Is it wanted or an error? Valentin.

Re: [Pharo-users] [Pharo-Users] Symbolic links

by Esteban Lorenzano

it has it. this is how is done in mac: *isSymlink = [[fileAttributes objectForKey: NSFileType] isEqualToString: NSFileTypeSymbolicLink] ? 1 : 0; and this how is done in linux: stat(unixPath, &statBuf) && lstat(unixPath, &statBuf) ... *isSymlink = S_ISLNK(statBuf.st_mode); â¦ and in windows is always false.

[Pillar]Â Pillar 3.0.0 release

by Thibault ARLOING

Hi everybody, I'm happy to announce the latest release of Pillar. This release has been possible because of the hard work of Damien Cassou, Cyril Ferlicot, Damien Pollet, Stephan Eggermont, Yann Dubois, Thibault Arloing and Lukas Komarek. What did it bring and what are the largest changes ? * Addition of an AsciiDoc Exporter * LaTeX exporter: * external links now produce footnotes * replace \begin{code}{} with \begin{listing}[language=XXXX] * replace \ct with \code * use \textasciitilde instead of \texttildelow to represent a ~ character in Pillar * SBALaTeX writer for sba book (by Damien Pollet) https://github.com/cdlm/sbabook * HTML exporter: * default template charset is UTF-8 * Features: For more you can see Pillar documentation at https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… * hideable scripts with the option hideable. * e.g., [[[hideable=true with a parameter in pillar.conf "scriptHide"=true this text will be hidden. ]]] * It's, for example useful if you're a teacher and you want to have two versions of your document, one with solutions (for you) and one without (for students) * auto anchor for headers * e.g, in a level configuration "level1":{ "numbering"=true, "autoAnchor"=true } there will be an automatic creation of an anchor for headers of level 1. * It's useful when you want to link a title in the text, for example for a table of contents * header capitalization in a level configuration with options: capitalize, capitalizeEnglish, uppercase, lowercase * ex: "level1":{ "capitalization":"uppercase" } Will render all headers of level 1 to Uppercase. * It's useful if you want all headers of a same level to be capitalize likewise * e.g., if you have "==i am a level 1 header" with "capitalizeEnglish" it will produce "<h2>I Am a Level 1 Header<\h2>" Cheers, Thibault
