- What is PickFile ?:
- ===================
-
-
- Under OS 2.xx it is now possible to use different sets of fonts,
- patters and mouse pointers and to change them in a very easy
- manner.
-
- Since I use this new system, I feel very happy if I use well
- designed wbench pattern or window pattern or different overscan
- sizes or different sets of fonts for my wbenchscreen.
-
- But if I have used e.g. a window pattern for a longer time, I
- usually want to change this pattern.
-
- So first I have to start the WBPattern program which is located
- in the `sys:prefs/` drawer ...
-
- After designing a new pattern, I have to save it as default.
- After some time of using this pattern the whole procedure starts
- again and again and not only for patterns than also for fonts
- colours etc..
-
- PickFile can help you.
- PickFile chose randomly an entry out of a list or optionally
- a file out of a drawer. Then PickFile executes this file or
- an optional commandline which must be supplied.
-
- PickFile has a variety of applications and is useful for
- starting all kinds of files and programs.
- PickFile (PF) is not only able to chose a file, but also
- to execute a whole commandline which has to be supplied.
-
- You can also ask PF to chose more than one entry by one call.
- To write about all possible kinds of aplications you may use
- PF for, I haven`t the time and imagination here.
-
- You can use PF for calling prefs files or to start sampled
- sounds (randomly) or just to create a slideshow with a randomly
- order of your pictures...
-
- I have also include an example in the examples drawer.
- I have also included some examples in this document.
- (See Tutorial).
-
-
-
- System Requirements:
- ====================
-
- PickFile needs kickstart 2.04 version 37L or better to run.
- Under version 36L (1.4) or 1.3 it is not able to run, because
- of the usage of some OS 2.xx only features for pattern matching
- and commandline editing.
- (Sorry).
-
-
- Legal Stuff:
- ============
-
- This program and all files come with it, also the docfiles, are
- released as FREEWARE.
-
- this means:
-
- everybody may use PickFile,
-
- everybody may copy PickFile, if:
-
- 1. You copy all included files, see list at the end of the
- doc file.
- 2. No changes are made, this means the program and all
- included files must stay in the original form.
- Exception: you may archieve it; but in this case you
- must also archieve the whole package.
- 3. If you recompile it, you have to include a notice to
- the original author. If you also want to (re)distribute
- in any new form you have to send me a copy.
- 4. You may not sell PickFile.
- Execption: you`re allowed to take a small copy fee
- which should not extend 5US$.
- 5. If you want to include PickFile
- or one of the included files as a part of a commercial
- package, you must have written permission of the
- author (address see below).
-
-
- I take no warranty or guaranty for the function of this program.
- The whole risk of using PickFile stays only by the user.
-
-
-
-
-
- PickFile Startoptions:
- ======================
-
- If you start PF from WBench, you will get only a short helptext.
- If you instead call PF from CLI, so it uses the following
-
- Syntax: [File=F/K][Dir=D/K][MinVal=M/N][MaxVal=X/N][Test=T/K]
- [Quiet=Q/K][Help=H/S][Cmd=C/F]
-
- File=F/K : If you specify file, than this file is read by PF.
- One line of this file will be randomly chosen. The
- given commandline will be used, if supplied one
- (see later Cmd). The File will be loaded in memory
- and then processed. This saves a lot of time.
- The syntax of this file will be described below.
- See also the examples section.
-
- Dir=D/K, : If you instead specify Dir no file will be processed
- but this dir is examined and a file of this dir
- will be randomly chosen. If given, a commandline
- will be used. (see later under Cmd). If you omit
- this commandline the chosen file will be started
- as an cli program.
-
- Pat=P/K : After Pat you can specify a pattern after AmigaDOS
- conventions. So only matched files will be processed
- and the selection can only be one of the matched
- files. The pat option will only be used if you use
- the dir option, otherwise this option will be ignored.
-
- MaxVal=X/N : Here you can specify the number of entries which
- should be chosen by PickFile. The maximum value depents
- on the number of lines by use the file options or the
- number of files when using the dir option. If you specify
- a larger number the maximum available value will be used.
- Default: 1
-
- Test=T/S : If you use Test, the given commandline or the
- chosen file will not be executed but displayed in
- the cli window. This means you can use this option
- to see which commandline would be executed when run
- PickFile without the Test option.
- (Great for testing and debugging settings).
-
- Quiet=Q/S : If you use instead the Quiet option, PF doesn`t
- tell you which selection is done and which command
- is executed. Usually PF informs the user about the
- commandline which is currently executed. If you want
- to call PF e.g. in your startup-sequence to select
- a set of patterns, then the output of PF would opened
- the shell window. If this option is used the window
- still stays closed.
- (see also AmigaDOS manual Shell-Flag (AUTO)).
- This option is also useful for batch files which
- should not print any output to a shell window.
- Default: OFF.
-
- Help=H/S : If you use Help or the commandline contains any error
- a short helptext will be printed out.
-
- Cmd=C/F : This is the most powerful option. After the Cmd
- keyword you can specify a whole command line with all
- kinds of arguments. This commandline will then be
- called after chosing an entry. This option is
- available under file and dir option.
- The commandline may be embedded in "",s but this is
- optional.
- But if you use another shell than the standard shell
- e.g. CShell, I will recomment, to do this to prevent
- pattern expandings before calling the commandline.
-
- All included []`s will be automatically replaced with
- the chosen entry. If you specify multiples selections
- this commandline will be called again for each entry.
- (see also MaxValue).
- So you can use PickFile also for recursion calls
- (BE VERY CAREFULL)
-
- For all options: you may use all options in any order.
-
- Exception: Cmd must be the last argument.
-
- All options are optional (what a surprise :-). But also here exists
- one exeption:
-
- You must either specify a file or a dir.
- If you specify a file and a dir the file will be processed and the
- dir ignored.
-
- The syntax for the file must follow this conventions:
-
- The file must be 100% ascii code. There must not exists any kind
- of comments, because, to handle this, would slow down the program
- too much.
-
- Each line represents a command line. If you also supply a command
- line (Cmd option), PF thinks it should pickup one or more lines
- of the file and replace the given []`s of the command line.
- So you see there should be no leading spaces in the lines.
-
-
- Examples:
- =========
-
- Now there are some example callings and commandline
- options and their use.
-
-
-
- 1. Example: lottery program
- ---------------------------
-
- This example is included in the examples drawer.
-
- Assuming you have a file calling `Lotto.dat` in the current
- directory which includes all numbers from 1 to 49 one number
- in each line.
- Assuming we want to chose 6 numbers randomly from 49 and we
- want to print out the selections you can use the following
- example commandline
-
-
- PickFile F Lotto.dat X 6 C "echo [] > PRT:"
- | | |
- | | ---> This command line will be executed for
- | | each chosen number.
- | |
- | ------> This tells PF to chose 6 different
- | numbers out of the file
- |
- ------------------> This is the file which cointains
- the used numbers
-
-
- 2. Example: Randomly using of wbpattern set
- -------------------------------------------
-
- Assuming we have several wbprefs patterns located in the
- sys:prefs/presets drawer (these can be designed with the
- WBPattern program and be saved with the menuitem Save As).
- Assuming these wbpattern sets are called `wb.1.pat`,
- `wb.2.pat` ... `wb.n.pat`. If you now insert the following
- line into you startup-sequence:
-
- .....
-
- PickFile D Sys:Prefs/Presets/ P "wb.#?.pat" Q C
- "Copy [] env:sys/wbpat"
- .....
- Endcli >NIL:
-
- ,so PickFile randomly picks up a set of these patterns each time you
- boot up. To process only the wb.##.pat files, we have to specify here
- Pat with the pattern 'wb.#?.pat' (for pattern matching see also
- AmigaDOS manual). With Q (for Quiet) no outputs will be sent to the
- shell window, so the AUTO boot shell window will not be opened.
-
- The commandline `Copy [] env:sys/wb.pat` will be replaced with
- e.g. (Assuming PF had chosen wp.1.pat).
-
- ====> Copy wb.1.pat env:sys/wb.pat
-
- After calling the IPrefs program in your startup-sequence this pattern
- file is used for the wbpattern (really good ?).
-
- You can use this example also to change other environments like i.e.
- screen sizes (NTSC-PAL or InterLaced/NON-Interlaced mode etc...)
- (this functions also later at any time). You must therefor only change
- the Pat and Cmd line patterns.
-
-
- 3. Example: Slideshow with several pictures in a randomly order
- ---------------------------------------------------------------
-
- Assuming we have a disk with the name `PICTURES:` and this disk
- contains 20 different picturs. So we simply can use the following
- example call to PickFile to create a full slideshow and starts it.
- I assume also that you have a picture viewer in the C: directory
- which is called Show.
-
- PickFile D Pictures: X 20 Q C "C:Show []"
-
- All 20 pictures will now be displayed in a randomly generated order.
- No outputs will be sent to the cli window. For each picture the
- commandline `C:Show []` with the chosen picture name instead of the
- []`s will be executed. I assume that C:Show can display the given
- picture when specified at start time.
-
- There is an endless list of other applications which can be used
- with PickFile.
- If you know any other interesting application please let me know.
-
-
- Technical:
- ==========
-
- I spoke in this manual often about randomly selections. The
- random generator routine is created by using the system time
- (micros) to initialize the ran() routine. The selection is
- then performed by calling sran().
-
- If you use multiple selections, I take care that each entry is
- chosen only once. Also if you specify more entries in a list or
- files that exists, only the correct number of entries will be
- used.
-
- To prevent errors in command line execution, the selection of
- drawers is not supported, they will be only ignored (certainly
- except in path specifications).
-
-
- At Last:
- ========
-
- I hope (really) that there are some people out there which
- are interested in this wonderful tool and stays here as your
