Jalatext: Utility to open and navigate immense files - mendenhallrearandeas
Information mining often involves hunting through files many gigabytes in size of it that are not amenable to quick filtering by scripts. Jalatext ($30, thirty-daylight free trial) is a tool configured to assistance you view, search and edit such files—and it can do it fast.
Written in Java, Jalatext is capable of opening rattling large (1 gig+) files almost instantly. Quite than churn madly trying to fit arsenic much of the lodge Eastern Samoa possible into RAM, it loads a small helping at once, keeping performance swift. The user can adjust the size of the loaded segments, in accord with their available RAM.
One time Jalatext is loaded, you hindquarters navigate by segment. If you tell it to load 10,000 lines at a time, each fall into place of the appropriate control will move to the next/anterior 10,000 lines. Or by scrolling within a segment. You can also rapidly go to the start/end of a file.
This points out one of the problems with Jalatext, namely, it's non painless to tell your comparative set in a data file.
Jalatext's status bar tells you the byte range being displayed, but non the dividing line number, which is far more useful for many purposes. The scroll bar tells you the relative position of what you'ray seeing inside the inebriated section, which is reputable, but there's little to provide a quick, intuitive, sense of your position inside the register itself. If you know the area you're interested in is, aver, line 234,500 out of 1 million lines, there is no "attend this line" function or statement.
One thing that john mitigate this is the use of bookmarks.
Jalatext allows you to scratch positions in a file, and rapidly affect between them. You arse also exportation altogether of the schoolbook between bookmarks, which is handy when hard to extract a large segment of data. When combined with the regex (Regular Expression, and if you need a program suchlike Jalatext, you either know what these are, operating room you need to learn) enabled search functionality, this can enable a lot of navigation shortcuts.
However, I've had freezes with Jalatext when doing searches in large files. I've worked around this by reducing the size of the file segment I chose to use.
Jalatext also has the power to salve the file in a different encoding, a boon when moving huge files from peerless OS to another, or making them readable by newer operating theatre older programs than the ones that output them, a common occurrent.
On the harmful side, Jalatext does not have any capacity to identify bounded files and to presentation the data in an easier-to-show format. Delimited (oftentimes comma or tab circumscribed) files are one of the all but common types of huge files, and this would be a peachy feature for approaching expansion.
Jalatext does a specialized job and does information technology well, but it's a bit bare-bones for the $30 monetary value. The 30-day test has no functionality restrictions, so that's ample clock time for anyone to trial it out and draw their own conclusions.
Note: The "Try it for freed" button along the Production Information page takes you to the trafficker's locate, where you can download the latest version of the computer software appropriate to your system.
