Re: [Pharo-users] Seaside : including a static stylesheet.
by Dominique Dartois March 1, 2017

March 1, 2017

Thank you Sven. I have tried successfully the FileLibrary but I want to be able to modify the stylesheet without using Pharo which will be running on a remote server. Using static documents seemed the solution to me. > On 28 Feb 2017, at 18:53, Dominique Dartois <dom(a)dartois.org> wrote: > > In the Seaside book, chapter 17.2 I read I can include a stylesheet this way : > > updateRoot: anHtmlRoot > super updateRoot: anHtmlRoot. > anHtmlRoot stylesheet url: 'http://seaside.st/styles/main.css' > > On my development machine (macOS) I use http://localhost:8080/myApp as the server address and I don?t know the root directory of the Seaside integrated web server. > > Can anyone help me to find this directory? The easiest way is to use a Seaside FileLibrary subclass to serve your static CSS file. This is described in that same chapter 17. > Thanks. --- Dominique Dartois

Voyage and Association
by Hilaire March 1, 2017

March 1, 2017

Hi, I am having trouble to persist in a Voyage repository Association formed with a key being a non string object (let's say a Month) and value a non basic object, instance of a model object. So far, I have an error bsonTypeCode not understood on my value object. I could implement bsonTypeCode, but I suspect I will have trouble too with the key, as I see from Voyage code it is persisted as a String. An idea how to overcome this (without modifying my model)? Fuel was persisting it fine. Thanks Hilaire -- Dr. Geo http://drgeo.eu

spotting methods with TODO, FIXME, etc. comments?
by Raffaello Giulietti March 1, 2017

March 1, 2017

Hi community, many IDEs for other language usually offer a way to annotate methods with special comments like "TODO ...", "FIXME ...". Such methods can then be later retrieved easily in task lists and selected by simple clicks. Is there something similar in Pharo? Thanks

Re: [Pharo-users] Problems with PipeableOSProcess

Hi Dave Okay, great, thanks for your pointers. I found the error stream. The error says /bin/sh: /Users/silas/Documents/ExtendedEggShell/Moose6.0/ExtendedEggShell/tools/mac/parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/ExtendedEggShell/Moose6.0/ExtendedEggShell/examplePDFsFromList/Ardi97aSchemeTeaching.pdf.txt: No such file or directory Iâll have to investigate on why this happens for one .txt file, but not for the other one (Ache00aScriptingCoordStyles.pdf.txt) in the same folder, even though I canât see any notable differences (like spaces, quotes, â¦) between the two filenamesâ¦ Thanks again for your help! Silas Hi Silas, I am travelling and cannot help much right now, but to answer one of your questions - yes, you can inspect errors in a PipeableOSProcess. It has an "error pipeline stream" that will contain any output from the stderr stream of the process. It also has a process proxy for the actual external OS process, which will show exit status for the process. In your case that probably will not help much, because you will just see exit status for the /bin/shell that you ran, not for the process that ran your perl script. Nevertheless it may be interesting to check it. One possible source of problems in a case like this is command line parsing. The command line that you pass from Pharo may get parsed differently than a normal bash terminal shell, especially with respect to quoting strings. Also, you refer to an empty string, which certainly sounds like it is related to the problem, although I cannot say why.

Problems with PipeableOSProcess
by Silas Berger March 1, 2017

March 1, 2017

Hi everyone, I'm currently experiencing problems with PipeableOSProcess. I'm using a command to run a third party tool, which reads a txt file and returns an XML string. In my collection, this works fine for about 75 out of 100 txt files, but fails on the remaining 25 ones. However, the tool itself doesn't fail. It works fine, if I issue the commands directly from a Terminal. Here's an example of a command string that works: /Users/silas/Documents/ExtendedEggShell/Moose6.0/ExtendedEggShell/tools/mac/ parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/ExtendedEggShell/Moose6.0/ExtendedEggShell/examplePDF sFromList/Ache00aScriptingCoordStyles.pdf.txt And here's an example of one that doesn't work. /Users/silas/Documents/ExtendedEggShell/Moose6.0/ExtendedEggShell/tools/mac/ parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/ExtendedEggShell/Moose6.0/ExtendedEggShell/examplePDF sFromList/Ardi97aSchemeTeaching.pdf.txt This is how I apply these commands through PipeableOSProcess: xml := (PipeableOSProcess command: cmdString) output. For the first command, xml is a large XML string, for the second command, it's just an empty string. As I've mentioned above, both commands work just fine in a Terminal. They both produce a correct XML string. Does anyone have an idea why this could be the case? Is there a way to access errors in the PipeableOSProcess, if there are any? Is there a better way to issue terminal commands from Pharo? Thanks for your help! Cheers, Silas

Voyage and Scaled decimal
by Hilaire March 1, 2017

March 1, 2017

Hi, It looks like Voyage, or Mongo, had a hard time with scaled decimal. I have an "Integer too large" error. Error: Integer too large: 1463035760746279168444519882918332074180871992424069768653697095674502345263300751487851490491702061753873077385550224188721036945253521387 May be at some time I will use float for efficiency, but in the mean time I would like to postpone optimisation and persist exact numeric value when possible.

Proof of Concept: FileTree and Fossil
by Pierce Ng March 1, 2017

March 1, 2017

Hi all, I have written a simple integration of FileTree with Fossil to avoid the 2-step Pharo- and shell-level work to add/delete/commit files. At the operating system command prompt, init a new Fossil project: os% mkdir ~/repo os% cd ~/repo os% fossil init myproject.fossil project-id: 3c05c3016eeabf8e87816ee218c6a86d3c87b950 server-id: ff42bc86dba1a26b1d94b64685f7c09d02581617 admin-user: laptop-user (initial password is "1fe2ff") Open the repository: os% mkdir ~/myproject os% cd ~/myproject os% fossil open ~/repo/myproject.fossil In a fresh Pharo 6 image - I used v60411 - install FossilFileTree: Metacello new baseline: 'FossilFileTree'; repository: 'github://PierceNg/FossilFileTree'; load. Write code in Pharo. Open Monticello Browser. Add a "fossilfiletree" repository, using ~/myproject as the directory. Save to said repository from within Monticello Browser. Done.

How to capture the execution of a playground?
by Offray Vladimir Luna CÃ¡rdenas March 1, 2017

March 1, 2017

Hi, I would like to store the object resulting from executing a playground. This would imply two steps: - Knowing that the playground content was executed (via the play button or its shortcuts Ctrl + Shift + g or Ctrl + g). - Getting the results of that execution. For example if the result at the end is a string or a dictionary, I would like to get that string or dictionary. Any pointers on how to make that will be welcomed. Cheers, Offray Ps: I still get lost when I search by myself trying to answer questions like the ones above. I imagine that in some way is related with evaluationAction and presentations, by looking for the source code of "do it and go", but still I can't get a functional code snippet to start prototyping.
