- BrowserII. Tutorial ( cont'd ).
-
- We assume that you have sent your contribution to the authors, and
- that consequently you are running version 2.02 or higher.
-
- This second part of the tutorial will be less "step-by-step", you
- should have gone through the first part and at least have glanced
- through the doc.
-
-
- 2. Advanced functions.
-
- Through three exercises, we are going to look into some interesting
- capabilities of BrowserII.
-
- In what follows, we will use the following semantics:
-
-
- ACT BrowserII->Options->Windows AutoZoom
- means: activate a menu item, or verify that an option in
- a menu is checked
-
- CMD dir opt a
- means: bring up the Command requester through
- BrowserII->Command or Right Amiga - C
- then type the commant text in it and click OK or press CR
-
- There is still a copy of your Workbench disk in df0:
- We call it "MyWorkbench".
-
- In the BrowserII->Options submenu, the following items are checked:
-
- Keep Selected
- Toggle Selections
- Move Files into Subdirectories
- Ask before moving Files into Subdirectories
- Asynchronous Action
- Windows AutoZoom
-
- In the Browser->Cmd Mode menu, Shell is checked.
-
-
- 2.1. Asynchronous mode.
-
- Please perform:
-
- CMD dir > ram:tutu df0: opt a
- CMD list > ram:toto df0:c
-
- You don't need to wait for the first command to finish before to
- launch the second one. The proof of their simultaneous operation
- is in the bad grinding noise coming out of your df0: drive.
-
- This is a rather dumb action, but it shows the point.
-
- Let's do something more sensible.
-
- CMD dir > ram:tutu df0: opt a
-
- While this command executes, go look in the Ram Disk for the contents
- of the Ram:tutu file, by selecting the appropriate line and
- launching the editor through the menus, like we did in the first
- part of the tutorial.
-
- You see here a big difference between BrowserII and most Directory
- Utilities, which can generally perform only one task at the time.
-
- You will be able to do simultaneously such things as copying
- from one drive to another, format diskettes, move files etc., the
- number of simultaneous actions is not limited to two.
-
-
-
- 2.2. The gauges on the left boarder of the windows.
-
- A little bit of preparation.
-
- Let's create in the Ram Disk a directory calles ApplePie, which
- will contain 4 files named q1 to q4.
-
- Open the Ram Disk window.
-
- ACT Actions->Makedir ApplePie
-
- In ApplePie, create with Ed or any editor a file saved as q1
- which contains any short length of text.
-
- Open the ApplePie window, a file q1 sits there.
-
- ACT Actions->Duplicate
-
- in the requester, change q1 to q2 and click OK.
-
- The same way, create the q3 and q4 files.
-
- Put in df0: a freshly formatted disketted, named e.g. MyDisk.
- Open its window.
-
- We are ready to look at the gauges.
-
-
- 2.2.1. Left gauge.
-
- Look at the leftmost gauge in the various windows.
-
- In the Ram Disk window, it shows "full" ( I won't talk about
- colors, because of the color mixup between 1.3 and 2.0 ).
-
- That's OK, the Ram Disk is always full, as it adjusts its size
- to its actual content.
-
- In the MyDisk window, the left gauge shows "empty", but if you
- make the window as tall as possible, you will see something,
- in case you have formatted the diskette with a Trashcan.
-
- Now take look at the left gauge of the main window. It always
- repeats the info given by the gauge of the active window.
-
- Go through the various windows and verify this.
-
-
- 2.2.2. Right gauge.
-
- This one is likely to give two different types of information,
- according to the item checked in the BrowserII->Options submenu.
-
- 2.2.2.1. First mode.
-
- ACT BrowserII->Options->Display Directory Disk Usage
-
- The gauge says how much space is occupied on a disk unit respectively
- by the subdirectories and the files of the root directory.
-
- In fact it works differently than the name suggests.
-
- Look at the MyWorkbench window. Most of the content of the
- diskette is in subdirectories, the gauge shows close to "empty".
-
- In the Ram Disk window, delete the files "toto" and "tutu"; there
- are now only directories in Ram: the gauge is fully down.
-
- Let's copy to the Ram Disk Window all the xxx.info files of the
- MyWorkbench window; the gauge goes up.
-
-
- 2.2.2.2. Second mode.
-
-
- ACT BrowserII->Options->Proportion of Visible Data
-
- Copy the xxx.info files of the MyWorkbench window into the ApplePie
- window.
-
- This window contains only visible files, the right gauge shows
- "full".
-
- Activate this window.
-
- ACT Actions->Filters->No .info
-
- The xxx.info files disappear. The right gauge now shows very close
- to "empty", because the q1....q4 files are very small.
-
- Now copy the file Ed from the C directory of the MyWorkbench
- diskette in the ApplePie window, the gauge goes up, but not the
- full way up, which tells us that there are in this drawer some
- files which are not displayed.
-
- Close the ApplePie window, and open it again. This time all files
- show up and the gauge says "full".
-
-
- 3. The Filters.
-
- The submenus and items of the Window menu are rather easy to
- understand, we will concentrate on the Filters submenu. The generic
- action of the filters is to control which files will be displayed
- in a window, by defining criteria for appearing
-
- Close all windows, except the MyWorkbench one.
-
- ACT Window->Filters->Set...
-
-
- Here comes a new requester.
-
- In the upper part, ther are two boxes where you see the words
- Files and Dirs, followed with an Y. If you click on a Y, you see
- that there are three possible choices: Y, N and ?
-
-
- Y for: always displayed
- N for: never displayed
- ? for: displayed if criteria are met
-
- So, if you select two Y's or two N's, the filters will be
- inoperative, in the former case all files will be displayed, in the
- latter, the window will be empty.
-
- Thus, select ? in both boxes.
-
- in the Pattern box, type *l* or #?l#?
-
- The window lists all files or directories whose names contain
- at least one time the letter "l".
-
- ACT Window->Filters->Invert
-
- Now you see only the names of files and directories which contain
- no "l".
-
- ACT Window->Filters->Clear
-
- All files and directories are back.
-
- Now that you got the mechanics of it, refer to the doc and make
- exercises.
-
-
- 4. The Custom Screen.
-
- If you are the lucky owner of a multisync monitor, or if you have
- any other solution to reduce the effect of flicker, why don't you
- try:
-
- ACT Workbench->Screen->Custom Interlace.
-
- BrowserII opens its own screen in hires interlace mode. The quantity
- of displayable information becomes very interesting.
-
- [ However, there is one side effect:
-
- if you launch a program, or try and look at a text with your
- editor,
-
- either the program or utility opens its own screen which pops up in
- front of Browser, that's OK
-
- or it opens a window in the workbench screen, which is then hidden
- by Browser's screen, and you could derive the impression that
- nothing happened. In this case you will have to send Browser's
- screen to the background via your preferred method. It will be
- the case in particular for AmigaDos commands.
-
- Consequently, if you use the custom screen, give preference to
- utilities like MuchMore or Mostra which open their own screen.]
-
-
- 5. Your comments, please.
-
- We thought that a program with very wide capabilities like
- BrowserII might be more easily approached through a tutorial.
-
- It is difficult for such a tutorial to be a real help for both
- the beginner and the seasoned Amigaman.
-
- So, why don't you drop us a line to tell us wether we achieved
- an acceptable balance.
-
- Your feedback will be greatly appreciated.
-
- Now, enjoy BrowserII !
