[Pharo-users] Scaled decimals comparisons

Hi, I was doing some basic calculations based on a formula, and I wanted to convert the result to a scaled decimal in order to avoid having these "loose" decimals in 10th position or something similar. So I did the following: 82 - (2 * 35.9) - (0 / 2) * (113/121) asScaledDecimal: 1 -> 9.5s1 But

[Pharo-users] CV/OCR Library

Hi, Does anybody know if there is an OCR or some CV library available for Pharo? I would like to make an experiment with recognizing the content of some fixed size form, and of course I prefer to do it with Smalltalk whenever possible. Regards! Esteban A. Maringolo

Re: [Pharo-users] PostgresV2 Driver available?

Hi, My question was done in a quest to crack an issue with Postgres which was already solved, and it involved the connection, but it wasn't the driver nor the server, but a firewall in between. So I don't see the need, nor I think it would be advisable, to use the v2 driver when the P3 is

[Pharo-users] Getting rid of .sources file for deployment

Hi, Is there a way to get rid the .sources file in a deployment scenario? I followed this guide [1], but I cannot get rid of the .sources files, because I'm using PharoADO (which uses PharoCOM) and it uses some reflection for FFI and for some reason that implies using the .sources file. I

[Pharo-users] Pharo.exe and PharoConsole.exe VM Difference

Hi, What is the difference between the Pharo.exe and PharoConsole.exe? They have the same size, but are binary different. I'd expect the PharoConsole to run headless by default, but it is not the case. So... is this documented anywhere? Thanks! Esteban A. Maringolo

[Pharo-users] Checking baseline before publishing

Hi, How can I check that my baseline works without having to publish everything, check that it fails and then going to the origin, fixing, etc? I might be particularly idiot to always miss something, I usually have to try at least four times (in a blank image) that my Baseline, dependencies,

Thanks Sean, I switched to use that, I didn't know about the "DO NOT CHECK OUT..." option. This sequence is so convenient it might be worth having as a single click option (repair > discard > do not checkout). Regards! Esteban A. Maringolo On Sat, Aug 22, 2020 at 8:24 AM Sean P. DeNigris

[Pharo-users] Iceberg "adopt commit" behavior

Hi, What does the "Adopt commit" mean? It seems like a rebase, but I'm not sure. I often have ongoing changes in my image, and also changes in the filesystem (css, js, Dockerfile, etc.). So what I do is to commit on the filesystem, and then "adopt" the recently created commit, and then commit
