Specifying the search path for "load" operations in ghci

Question

In Loading source files it states that the search path for finding source files is specified with the -i option : ``` ghci -idir1:...:dirn ``` Does this mean that when one performs : ``` :load test.hs ``` then ghci looks in the directories above for test.hs? I saw the response at Problem Specifying Source Directory to GHC but I am still not clear about this. For example in Windows XP I put test.hs in : ``` C:\Documents and Settings\winuser\My Documents ``` and then ran : ``` ghci -iC:\Documents and Settings\winuser\My Documents ``` However upon doing `:load test.hs`, ghci complained about not being able to find the file. [EDIT 1] I want to avoid using `:cd` because it unloads all loaded modules, which prevents me from loading files from multiple locations [EDIT 2 : response to jozefg] ``` --C:\A\A.hs module A where myaddA::Int->Int->Int myaddA x y = x+y --C:\B\B.hs module B where myaddB::Int->Int->Int myaddB x y = x+y ``` Then I can do the following : ``` Prelude> :cd C:\A Prelude> :l…

Accepted Answer

The load path is how GHCi searches for modules. So if you named your module `Test.hs` and added

```
 module Test where
```

Than you can do

```
 > :load Test
```

otherwise you can use

```
 > :cd SomeDirectory
 > :load test.hs
```

Response to edit:

(Warning, I run eshell so the commands/paths look different)

```
~         $ mkdir temp
~         $ mkdir temp/temp temp/temp2
temp      $ find-file temp/A.hs
-- In A.hs
module A where
addA = (+)
--
temp      $ find-file temp2/B.hs
-- In B.hs
module B where
addB = (+)
--
temp      $ cd temp
temp/temp $ ghci -i../temp2
> :load A B
> import B
```

And now I have access to both `A` and `B`.
