Then someone is sure that does not use a code, that needs {home} directory, but cannot. Maybe there could be a specialized error class for this. Now it uses Error, if I remember well.

Re: [Pharo-users] UUIDGenerator

by phil＠highoctane.be

Spotting for hex is hardly complex. Shift-Enter hex #im --> implementors of hex, first one I see is in ByteArray. Shit-Enter hex #se --> senders of hex. First one is a test in ByteArray testHex "self debug: #testHex" self assert: #[122 43 213 7] hex = '7a2bd507'. self assert: #[151 193 242 221 249 32 153 72 179 41 49 154 48 193 99 134] hex = '97c1f2ddf9209948b329319a30c16386'. self assert: (ByteArray readHexFrom: '7A2BD507') = #[122 43 213 7]. self assert: (ByteArray readHexFrom: '7a2bd507') = #[122 43 213 7]. >From this test, one can spot readHexFrom: which uses lowercase or uppercase for reading. And asUppercase, Shift-Enter upper, scrolll down as bit, find String>>#asUppercase Spotter is really great at finding stuff, and coupled with tests and examples it helps in building understanding. Agreed, this is not the same as looking for stuff as in, say, Java or Python. I find it better in the long run still.

Re: [Pharo-users] Finding files in Pharo

I know file system commands could be executed using the OS wrappers. But Smalltalk is more elegant than shell command line, and we have Windows still the most used OS. 2017-06-18 3:59 GMT-03:00 john pfersich <jpfersich(a)gmail.com>: > Why not just use OsProcess or OsSubprocess to run the unix commands (works > on Mac OS and Linux)? > > Sent from my iPhone > > > On Jun 17, 2017, at 19:59, HernÃ¡n Morales Durand < > hernan.morales(a)gmail.com> wrote: > > > > I would like to find files in Pharo like the UNIX find command: > > > > find . -iname "*.txt" -type f -print > > > > find . \( -iname "*.txt" -o -iname "*.csv" \) -print > > > > find . -maxdepth 2 -name "example*" -type f -print > > > > find . -type f -atime -7 -size +2M -perm 644 -print > > > > Do we have some package on top of FileSystem to make complex find > searches? > > > > HernÃ¡n > > > >

Why not just use OsProcess or OsSubprocess to run the unix commands (works on Mac OS and Linux)?

Re: [Pharo-users] Finding files in Pharo

by Sven Van Caekenberghe

HernÃ¡n, We obviously don't have as many options as find, but this should get you started: Check the category 'enumerating' in AbstractFileReference, with methods like #childrenMatching: and #allChildrenMatching: Once you have a reference, you can use other meta data, see the 'accessing' protocol to further your query.

Finding files in Pharo

by HernÃ¡n Morales Durand

I would like to find files in Pharo like the UNIX find command: find . -iname "*.txt" -type f -print find . \( -iname "*.txt" -o -iname "*.csv" \) -print find . -maxdepth 2 -name "example*" -type f -print find . -type f -atime -7 -size +2M -perm 644 -print Do we have some package on top of FileSystem to make complex find searches?

Re: [Pharo-users] Prolog in Pharo

by Evan Donahue

Hi, Yes, I am planning to move it to github, which is part of why I didn't get around to keeping the sth version synced. I have just managed to get iceberg working, so hopefully I won't have any trouble uploading it. That said, I am still a little unclear on how to specify dependencies on other repositories when using github (since I have typically been generating them and committing through versionner), so if anyone can point me to any resources about that, I'd appreciate it.
