- What is whelp?
- --------------
-
- whelp is a small program that provides a command line interface to the
- winhelp help system in Microsoft Windows. The command line syntax is
-
- whelp [/F helpfile] topic
-
- (You can use -f instead of /F if you prefer)
-
- This invokes winhelp with a helpfile and searches for the topic. If no
- topic matches then winhelp lets you search interactively. If no helpfile
- is specified the default is win31wh.hlp (the SDK reference).
-
- That's all. Not very useful in itself, but it can be used in conjunction
- with other tools to build useful systems.
-
-
- How to use whelp
- ----------------
-
- Since whelp is a windows program it must be run from within windows.
- You can either use the "Run" menu item in program manager (or other
- applications) or you can use a utility that allows windows programs to
- be executed from a DOS prompt.
-
- I know of three such utilities (I use run.zip),
-
- run.zip - available from most windows software archives.
- wrun.exe - available with backmenu and backdesk, also in
- most windows archives.
- wx.exe - a utility that comes with Microsoft C/C++ 7.0
-
-
- One way to use whelp
- --------------------
-
- I wrote whelp to use in conjunction with my editor of choice (elvis, a
- vi clone) when I am developing windows applications. The following vi
- macro allows me to place the cursor over a word (eg a function call or
- type) and press ^W to look it up in the SDK reference. It works in a
- similar way to ctags, but for the SDK instead of your own code. You
- could have a similar macro to invoke Microsoft's qh program (for text
- mode help).
-
- " invokes winhelp for the word under the cursor
- map ywop^i:! run whelp ^"add@a
- " invokes qh for the word under the cursor
- map ywop^i:! qh ^"add@a
-
- NOTE:
- To enter this in your vi startup file (using vi) you need to enter
- the control codes explicitly by escaping them with ^V - that is, you
- actually press,
-
- map (ctrl-V)(ctrl-W) ywo(ctrl-V)(ESC)p^i:! run whelp (ctrl-V)(ESC)^"add@a
-
- There is no reason why whelp should not be used in a similar way with
- other editors. I beleive that brief, epsilon and emacs variants will all
- allow similar behaviour.
-
- Using whelp with elvis
- ----------------------
-
- If you are using elvis in particular there is the K command to look up a
- keyword using a program. This is better than the macro above since the
- cursor can be anywhere in the word and there is less rubbish on the
- screen. The equivalent mappings for your elvis startup file would be,
-
- " invokes winhelp for the word under the cursor
- map :set kp="run whelp"
- K
- " invokes qh for the word under the cursor
- map :set kp=qh
- K
-
- Thanks to Uri London for pointing out the K command in elvis.

- For the future
- --------------
-
- whelp is so small there shouldn't be any bugs in it, but if you find any
- you can tell me at the address below. I am interested in any other ideas
- for using whelp and any improvements you might suggest (or implement).
- The distribution contains the C source and a makefile for whelp which
- compiles under Windows 3.1 using Microsoft C/C++ 7.0 and the SDK.
