Etip documentation
|
|
===================
|
|
|
|
Etip is 'Tip of the Day' program which will show tips about EDE usage.
|
|
It is also capable to show fortune-like tips, reading fortune files.

Details
|
|
-------
|
|
|
|
Etip will be usually invoked when EDE is started, and if you don't want
|
|
this, you can always uncheck 'Show tips at startup' checkbox.
|
|
|
|
Etip will read tips from fortune-like file, which is based on two parts:
|
|
|
|
* file with tips
|
|
* a companion with *.dat* extension
|
|
|
|
File with tips is plain text file in human readable form and is main source where
|
|
you should add, changed and delete tips. Each tip is separated with *%* character
|
|
at the beginning of the line, and (as advice), those should be nicely formatted
|
|
(proposal is to use around 66 characters per line so they can nicely fit inside
|
|
etip window).
|
|
|
|
*.dat* file is binary file and does not contain any tip strings; it have only
|
|
offsets to those in plain text file to allow fast random access to any of
|
|
specific tip string. *.dat* files are created with 'etip-compiler' command (see bellow
|
|
for the details), and must be updated each time when a source file with tips is updated.
|
|
|
|
[NOTE]
|
|
Both files must exists so etip can read the content.
|
|
|
|
Example
|
|
-------
|
|
|
|
Let we as example create simple tip file, named 'demo' with some content.
|
|
|
|
--------------
|
|
This is tip one.
|
|
%
|
|
This is tip two. Nice.
|
|
%
|
|
This is tip three. Progress, man, progress :)
|
|
%
|
|
--------------
|
|
|
|
[NOTE]
|
|
Please let end line in each tip contains *%* character. With this we retain a small
|
|
compatibility with fortune
|
|
|
|
Now save this file in 'demo' and invoke 'etip-compiler' on it. Doing that is like:
|
|
--------------
|
|
etip-compiler demo
|
|
--------------
|
|
|
|
You will see output like this:
|
|
--------------
|
|
"demo.dat" created
|
|
There were 3 strings
|
|
Longest string: 46 bytes
|
|
Shortest string: 17 bytes
|
|
--------------
|
|
|
|
Output from 'etip-compiler' shows some informations you probably don't need and, most important,
|
|
it shows that he created *demo.dat* file. If you want to suppress these outputs, just
|
|
use '-s' flag, like:
|
|
|
|
--------------
|
|
etip-compiler -s demo
|
|
--------------
|
|
|
|
'etip-compiler' will, by default, use input name and append *.dat* suffix; the best way is to keep
|
|
it like that since etip expects names of tip file and .dat file are the same (or will not be able
|
|
to find .dat file). 'etip-compiler' have some more options, and for the details see below.
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
Etip does not have command options and the only file it reads (beside tip files) is 'etip.conf'.
|
|
This file should contain path to the tip file name. Here is the sample:
|
|
|
|
--------------
|
|
[etip]
|
|
Path = /usr/share/ede/tips/ede
|
|
--------------
|
|
|
|
[NOTE]
|
|
Make sure in the same directory exists *.dat* file.
|
|
|
|
|
|
etip-compiler details
|
|
---------------------
|
|
|
|
As you could see from the previous text, 'etip-compiler' is simple command line tool that will
|
|
create .dat files. It will correctly scan tip file, calculate offsets (and something more) and spit
|
|
that in the file that etip understands.
|
|
|
|
[NOTE]
|
|
You must invoke etip-compiler each time you change file with the tips or .dat companion will contains
|
|
incorrect data.
