Hi all

What does everyone use when writing their code. I have the xHarbour Language Reference Guide version 1.1 (I had an enterprise subscription) that I assume is copyright. The information is pretty good (although it pretty much ignores any Linux consideration) and some of the navigation is either awkward or not working correctly. Its a pdf and I think subject to commercial copyright?

I also have a pdf Harbour Guide which I assume is copyright also but free to use and distribute? Navigation doesn't work correctly in my copy of that either - I think pagination was changed after the links were established.

Antonio has produced some nice documentation on FiveWin (I probably don't have the latest) and more basic but quite good on Five Linux but not really designed for quick on-line use.

I would like to be able to quickly call up documentation on a particular function or class or command etc in a little on line application. Does one exist? Should one exist?

I did just have a quick look at the Harbour Guide and copied the text to a text file and then wrote a quick and dirty xBase program to split up each topic and put it into a memo field and extract the topic (title) and copy it to another field. So that might be a rather crude beginning for a partial system if indeed none really exists.

I have found that even with the rather classy xHarbour reference I have had to use the Harbour guide for functions such as __ObjSetValueList().

Any suggestions / comments ?

Happy coding

Doug,

For standard Clipper docs, you can use:
http://www.ousob.com/ng/53guide/
http://www.ousob.com/ng/cltech/

For specific Harbour info, you can review its source code. It helps many times.

Hi Antonio

Thanks for the information.

Since I am still frustrated by the awkwardness of finding information in the available documentation I thought that a useful first step might be to convert the Harbour Guide to a series of html pages, a process which I have commenced. About 80 to 90% of the conversion I have been able to do with a little xHarbour program I wrote for the purpose but then comes the tedious task of doing the remaining changes and putting togther "index pages". To date I have converted topics that begin with A through C and T through Z plus made a start on D, S and I. To give you an idea of the output here's the html for a sample page:

Code: Select all Expand view: <html><head><title> ACOPY() </title></head><body><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <a href="h_functions.html">Functions</a> <a href="hf_array.html">Array-Functions</a><hr> <h1>ACOPY()</h1><p> Copy elements from one array to another </p><h3>Syntax</h3><p> ACOPY( <var><aSource></var>, <var><aTarget></var>, [<var><nStart></var>], [<var><nCount></var>], [<var><nTargetPos></var>] ) --> aTarget </p><h3>Arguments</h3><p> <var><aSource></var> is the array to copy elements from.<br/><br/> <var><aTarget></var> is the array to copy elements to.<br/><br/> <var><nStart></var> is the beginning subscript position to copy from <var><aSource></var><br/><br/> <var><nCount></var> the number of subscript elements to copy from <var><aSource></var>.<br/><br/> <var><nTargetPos></var> the starting subscript position in <var><aTarget></var> to copy elements to. </p><h3>Returns</h3><p> <var><aTarget></var> an array pointer reference </p><h3>Description</h3><p> This function copies array elements from <var><aSource></var> to <var><aTarget></var>. <var><nStart></var> is the beginning element to be copied from <var><aSource></var>; the default is 1.</p><p> <var><nCount></var> is the number of elements to be copied from <var><aSource></var>; the default is the entire array.</p><p> <var><nTargetPos></var> is the subscript number in the target array,<var><aTarget></var>, to which array elements are to be copied; the default is 1<p></p> This function will copy all data types in <var><aSource></var> to <var><aTarget></var>. If an array element in <var><aSource></var> is a pointer reference to another array, that array pointer will be copied to <var><aTarget></var>; not all subdimensions will be copied from one array to the next. This must be accomplished via the ACLONE() function.<p></p> Note If array <var><aSource></var> is larger then <var><aTarget></var>, array elements will start copying at <var><nTargetPos></var> and continue copying until the end of array <var><aTarget></var> is reached. The ACOPY() function doesn't append subscript positions to the target array, the size of the target array <var><aTarget></var> remains constant. </p><h3>Examples</h3><pre> LOCAL nCount := 2, nStart := 1, aOne, aTwo aOne := {"HABOUR"," is ","POWER"} aTwo := {"CLIPPER"," was ","POWER"} ACOPY(aOne, aTwo, nStart, nCount) </pre><h3>Status</h3><p> Ready </p><h3>Compliance</h3><p> This function is CA Clipper compliant </p><h3>Files</h3><p> Library is vm </p><h3>See Also</h3><p> <a href="h_ACLONE.html">ACLONE()</a> <a href="h_ADEL.html">ADEL()</a> <a href="h_AEVAL.html">AEVAL()</a> <a href="h_AFILL.html">AFILL()</a> <a href="h_AINS.html">AINS()</a> <a href="h_ASORT.html">ASORT()</a> <br/><hr><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <a href="h_functions.html">Functions</a> <a href="hf_array.html">Array-Functions</a></body></html>

I will have an alphabetical index but also you will see from the header and the footer that I am producing functional indexes too such as this one for array functions:

Code: Select all Expand view: <html><head><title>(Harbour) ARRAY FUNCTIONS</title></head><body><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <a href="h_functions.html">Functions</a> <hr> <h1>(Harbour) ARRAY FUNCTIONS</h1><p> <br/> <a href="h_AADD.html">AADD()</a><br/> <a href="h_ACHOICE.html">ACHOICE()</a><br/> <a href="h_ACLONE.html">ACLONE()</a><br/> <a href="h_ACOPY.html">ACOPY()</a><br/> <a href="h_ADEL.html">ADEL()</a><br/> <a href="h_ADIR.html">ADIR()</a><br/> <a href="h_AEVAL.html">AEVAL()</a><br/> <a href="h_AFIELDS.html">AFIELDS()</a><br/> <a href="h_AFILL.html">AFILL()</a><br/> <a href="h_AINS.html">AINS()</a><br/> <a href="h_ARRAY.html">ARRAY()</a><br/> <a href="h_ASCAN.html">ASCAN()</a><br/> <a href="h_ASIZE.html">ASIZE()</a><br/> <a href="h_ASORT.html">ASORT()</a><br/> <a href="h_ATAIL.html">ATAIL()</a><br/> <a href="h_LEN.html">LEN()</a><br/> <br/><hr><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <a href="h_functions.html">Functions</a> </body></html>

Currently I have entries in the following groupings (more will no doubt come as I convert more pages)

Code: Select all Expand view: <html><head><title>Harbour Functions</title></head><body><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <hr> <h1>HARBOUR FUNCTIONS</h1><p> <a href="hf_array.html">Array-Functions</a><br/> <a href="hf_control.html">Control-Functions</a><br/> <a href="hf_convert.html">Conversion-Functions</a><br/> <a href="hf_datafile.html">Data-File-Functions</a><br/> <a href="hf_date.html">Date-Functions</a><br/> <a href="hf_filesystem.html">File-System-Functions</a><br/> <a href="hf_internal.html">Internal-Functions</a><br/> <a href="hf_keyboard.html">Keyboard-Functions</a><br/> <a href="hf_maths.html">Mathematical-Functions</a><br/> <a href="hf_screen.html">Screen-Functions</a><br/> <a href="hf_string.html">String-Functions</a><br/> <a href="hf_test.html">Test-Functions</a><br/> <a href="hf_time.html">Time-Functions</a><br/> <a href="hf_UI.html">UI-Functions</a> <br/><hr><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> </body></html>

I'm not just converting pages related to functions as you can see from this higher level page

Code: Select all Expand view: <html><head><title>HARBOUR DOCUMENTATION</title></head><body><a href="xbase.html">xBase</a> <hr> <h1>HARBOUR DOCUMENTATION</h1><p> <br/> <a href="h_commands.html">Harbour-Commands</a><br/> <a href="h_functions.html">Harbour-Functions</a><br/> <a href="h_information.html">Harbour-Information</a><br/> <a href="h_objects.html">Harbour-Objects</a><br/> <a href="h_setcommands.html">Harbour-Set-Commands</a><br/> <br/><hr><a href="xbase.html">xBase</a> </body></html>

Eventually I would like to have Five Linux, xHarbour as entries form the top level screen

Code: Select all Expand view: <html><head><title>xBase DOCUMENTATION</title></head><body> <hr> <h1>xBase DOCUMENTATION</h1><p> <br/> <a href="harbour.html">Harbour-Documentation</a> <br/><hr> </body></html>

There are lots of maybes if other people are interested in this type of project. Perhaps someone might like to work on documenting FiveWin in the same or a similar format? I want to look in greater depth at the best format for documenting classes/objects but have converted the page for Harbour's TBROWSENew. I will include it in my next post.

I am learning as I go because I didn't have this information when I started and tend only to look at the documentation (such as it is) when I need to know how to do something or to check syntax. But the result of this is that it is easy to overlook helpful features / opportunities.

I also note the number of times people have asked questions in these forums about doing something in FiveWin only to find out that there is a method available in the appropriate class that does exactly what they want but it wasn't in the documentation and they didn't look at the source code.

Hi Antonio

I am also converting "information pages", for example:

Code: Select all Expand view: <html><head><title>Strong Typing</title></head><body><a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <a href="h_information.html">Information</a> <hr> <h1>Strong Typing</h1><p> Compile-Time type checking </p><h3>Description</h3><p> Strong Type Checking, could also be described as "Compile-Time Type Checking". As you might know Clipper, generates a Run-Time Error, ("Type Mismatch") when we attempt to perform some operations with the wrong type of Variable. </p><h3>Examples</h3><pre>: LOCAL Var1 := "A" ? Var1 * 3 // Error here. @ Var1, 7 SAY 'Hello' // Error here. ? SubStr( "Hello", Var1 ) // Error here. </pre><p> The above 3 lines would all result in Run-Time Error, because Var1 is of type CHARACTER but the above lines used it as if it was of type NUMERIC.</p><p> Using Strong Type Checking, or Compile-Time Type Checking, the above problem would have been discovered and reported in COMPILE-TIME, rather than waiting for the inevitable problem to be discovered when we finally execute the program. Strong Typed Languages allow the programmer to "tell" the compiler (declare) what is the type of a each Variable, so that the Compiler in return can warn the programmer, when ever such Declared (Strong Typed) Variable, is used in a context which is incompatible with its declared type.</p><p> For instance, if we "told" the compiler that Var1 above is of type CHARACTER</p><pre> LOCAL Var1 AS CHARACTER </pre><p>the Harbour Compiler could, in return, warn us if we attempted to perform the calculation:</p><pre> Var1 * 3</pre><p> because the Compiler knows we can't perform a multiplication of a Character. (we might allow it in some context, but this is beyond the scope of this discussion). Similarly we would have been warned when attempting to use Var1 as a Row Number </p><pre> @ Var1 </pre><p> or as the 2nd operand of the SubStr() function </p> <pre>SubStr("Hello", Var1) </pre><p> because the Compiler knows that these operations require a NUMERIC rather than CHARACTER type.</p><p> The above may save us lots of time, by pointing a problem, we can not escape, since such code will never perform correctly once executed. So rather than wait to the testing cycle, for such problems to be discovered, (and some times even later, after we may have distributed our applications) instead we may know of such problems as soon as we type </p><pre>HARBOUR ProgName -w3</pre><p> Harbour also offers a hybrid mode, where it can report such type mismatch problems, even without requiring the programmer to declare the type of variables. This feature, is referred to as Adaptive Type Checking. The programmer, is not required to make any changes in his code, to take advantage of this feature. All of the above 3 errors would have been reported just as effectively as if the programmer Strong Typed (declared) Var1. Harbour would have been able to report such problems at compile time,because the assignment</p><pre> Var1 := "A" </pre><p>implied that Var1 is of type CHARACTER,until it will be assigned another value. Therefore Harbour will "remember" that Var1 "adapted" type CHARACTER, and thus the subsequent multiplication</p><pre>Var1 * 3</pre><p> will be reported as an error, as soon as you attempt to compile such code.</p><p> The nice aspect of this hybrid mode, is that unlike Strong Typed Variables,you don't have to declare the type, so no code changes are need, the Type instead is assumed by implication (type of the assigned value). The other benefit, is that it is completely ok to assign a new value of different type, any time, to such undeclared (variant) variable. As soon as we assign a new type, the Compiler will than protect us from using the Variable in an incompatible context, since the variable "adapted" this type as soon as we assigned a value which implies a type.</p><p> While Adapted Type Checking may be fairly effective in reporting many common mistakes, to take full benefits of such Compile-Time checking, it is recommended to do declare the Type of Variables, when ever possible.</p><p> The Harbour Strong Type features, also allows the declaration of the expected parameters (including optionals) of User Defined Functions, as well as their return Type. Similarly, you may declare the Type of any Class Variables, Methods, and Methods Parameters.</p><hr> <a href="xbase.html">xBase</a> <a href="harbour.html">Harbour</a> <a href="h_information.html">Information</a>

I realise that the documentation has its limitations - it isn't at all comprehensive, its not consistent, some of the examples aren't that illustrative etc. But it seems like a great starting point if I can get a number of people using it and improving it. I would like to convert the xHarbour documentation and cross reference the two but as it is / was a product you had to pay for that may not be legally possible.

Would you mind me putting FiveLinux documentation in such a form?

Doug,

We can give you write access to our Wiki where you could upload all the FiveLinux docs and modify them, enhance them, etc. so other users may cooperate too:

www.fivetechsoft.com/wiki

Edited: I just reviewed it now, and I saw that we already gave you write access to it, but you have not used it yet :-)

Hello,

I always use our online xHDN (xHarbour Developers Network) pages to lok up anything regarding xHarbour. http://www.xHarbour.com/xHDN

Its always up to date.

Hi all

I've done a page for the FiveLinux TWindow Class. I'm trying to make the layout / contents easy to use / follow. I would be interested in comments / suggestions. I have started with TWindow because this information should probably be included on pages relating to its many subclasses. Its easy to overlook capabilities of parent classes when using their child classes.

Doug,

Why don't you include it in the wiki so its easier to be read and to cooperate to modify it, etc. ? :-)

Hi Antonio

I logged on to the wiki and uploaded my html code. It seems that the wiki is configured not to support embedded html code. I ratgher gather that you are the person that would need to change that configuration option. I gather from the wiki documentation that this does represent a bit of a security risk if you had a malicious person with edit access. I did put up a page bwith the html code and a test page where I started converting to the straight wiki code. The table capabilities with the straight wiki code don't include rowspan unfortunately which is a problem with my current layout design. Please advise if you are happy to enable html support.

Regards

Doug,

Better, easier and safer not to use HTML code.

You can copy and paste your text and format it using the wiki formatting tools. There are great wikis built using DokuWiki:

Hi Antonio

I have reformatted the TWindow documentation into a form suitable for the wiki and put it there. The thing I am not so keen about is that it presumably isn't in a form that can be easily downloaded onto a machine locally and run locally. So maybe I need to look into a way of producing both forms in one basic go - perhaps with some reformatting program.

Doug,

It looks excellent now! :-)

Many thanks!

A sugestion: we should use a namespace for each FiveTech product. i.e.: flh_twindow, fwh_twindow, etc.

Also, I remember there was another way. I need to review it...
