Re: [Pharo-users] OrderedCollection get all lines

There's also PositionableStream >> #nextLine which lets you write code like [readStream atEnd] whileFalse: [(self regexMatch: readStream nextLine) ifNotNil: [:matchingLine | "Record match somewhere here"]] Cheers, Henry -- View this message in context: http://forum.world.st/OrderedCollection-get-all-lines-tp4894314p4894324.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Thanks you again Sven, it will work with that, but there is nothing on Streams? 2016-05-11 16:19 GMT+02:00 Sven Van Caekenberghe <sven(a)stfx.eu>: > Did you see #lines and #linesDo: ? > > > On 11 May 2016, at 16:15, Valentin Ryckewaert < > valentin.ryckewaert(a)gmail.com> wrote: > > > > Hi, > > > > I would like to reproduce the grep command in Pharo. > > To do it I wanted to get the content of a stream and transform it to an > OrderedCollection (to use matchesRegex: on it). > > > > First of all, is there an easier way to do it? > > In a second time, is there a method to get the content of a Stream as an > OrderedCollection ?

OrderedCollection get all lines

by Valentin Ryckewaert

Hi, I would like to reproduce the grep command in Pharo. To do it I wanted to get the content of a stream and transform it to an OrderedCollection (to use matchesRegex: on it). First of all, is there an easier way to do it? In a second time, is there a method to get the content of a Stream as an OrderedCollection ? (nextLine exists so I could use it to get my OrderedCollection but is there an easier way?)

Hi, For temporary files you can create a new file in memory via `FileSystem memory` so you do not pollute your file system and the file will be deleted later since the memory is volatile. `file := FileSystem memory / 'tmp.txt'. file ensureCreateFile. file writeStreamDo: [ :s | s nextPutAll: 'Hello World' ].` -- Cyril Ferlicot http://www.synectique.eu 165 Avenue Bretagne Lille 59000 France
