How do you change your nim package's tags or description after you've published
it?
Thank you, that worked. I created a config.nims file in my main folder and
added one line: switch("define", "ssl")
Where do I put the line: switch("define", "ssl")?
I tried a few more things without luck:
* I tried adding a "before build" task:
before build:
switch("define", "ssl")
Run
* I tried adding it by itself in the my project nimble file.
* I tried adding it t
My nim package needs the -d:ssl compile switch. How do I add the switch to the
nimble build task used by nimble install? I tried a number of things but none
of them worked for me.
* I tried making a cfg file with the line "-d:ssl" in it.
* I tried adding a switch("d", "ssl") in a nimble buil
I’ve been thinking about this problem for a while too.
I copied Jonesmartinze three options here and numbered them for easier
reference.
1\. create a source distribution of .py and .c files. The end user builds this
so it matches their system architecture/OS.
2\. and/or create platform specifi
I've been looking for another approach. From what I've read, the python wheel
package can do what I want, but it is still a mystery to me how.
Has anyone done this and know of a project I can learn from? I haven't been
able to find an example in the python or nim public package lists.
The nimformat project on github uses nim with nimpy to build a python module
that can be packaged and installed with python's package manager (pip). The
package includes the c source files and pip compiles them to build the python
module on the target machine.

Is it possible to pass arguments to nimble tasks? I want to pass the filename
to run one test like this:

thank you, that did the trick
I'm getting warnings about modules imported but not used and I want to fix my
code. The second time I compile the warnings to do show up. How do I get the
warnings to appear again? The second compile is much faster, so I'm thinking I
might have to delete the cache. Is this correct? Where is it?
Here is the code if you want to try it out:
x.nim file:
var x = 0
if x > 1:
echo "foo"
echo "bar"
Run
ct.sh file:
#!/bin/sh
# Remove old coverage information.
rm -rf *.info html ~/.cache/nim
# Compile t.nim modul
I'm trying to get nim code coverage working again in the new nim 1.0 version.
It was working several months ago. Now it's reporting coverage on the c code
instead of the nim lines. The html output shows 100% coverage on the x.nim.c
file when it shouldn't and the standard lib files are not stripp
How do you use the memTracker compiler option to track memory usage?
What I tried was:
* added --memTracker:on to the compile line
* added line to my main module to import nimtracker
When I run my program, the memtracker.db file gets created and sqlite3 can view
it. However the tracker ta
How do you customize the html css output created by the nim rst2html command?
I was able to edit the compiler's config file
(~/.choosenim/toolchains/nim-0.19.0/config/nimdoc.cfg) to customize the css and
I saw the changes in the css output.
However, now I'm trying to do it with my own config fi
My nim program crashes in release but not in debug mode. Some system code is
overwriting my json structures causing the crash. The problem is hard to narrow
down, it moves around as I add debugging code. I haven't been able to simplify
the error case to something that is easy to share.

think it is a great idea and it might be implemented in nim with a macro. If
you know the entries at compile time, why not make the map as fast and small as
possible. In the compi
There's not an exportcpp pragma in nim that I know about. But have you tried
wrapping the nim c code with, extern "C"? Cpp code can compile wrapped c code.
Instead of typing r the second time, type "continue" instead. Then your program
will run and stop at breakpoints.
The answer to my question in another thread lead to the answer to this one.
Replace the "compile error" line with:
static:
doAssert(false, "T is not a string")
Run
The the doAssert will run at compile time.
How do you gracefully stop the compiler? You can specify garbage to stop it,
but is there a better way?
static:
echo "compiling..."
proc display[T](message: T) =
when not (T is string):
compile error: "T is not a string"
echo message

So this is expected nimvm behavior? I thought it would operate like static.
This works as I expect:
static:
echo "compiling"
echo "running"
Run
The "compiling..." string does not appear when compiling this program:
when nimvm:
echo "compiling..."
else:
echo "running..."
Run
I am trying to debug a python module I wrote in nim using lldb on a Macintosh.
Anyone know how to debug a python module?

I upgraded from nim version 0.17 to 0.18 and I'm in the process of updating my
code to remove the deprecated warnings.
What is the replacement for parseopt2?
Thanks. My problem was using the wrong escape code.
Here are some examples of showing [Suite] in bold blue.

Bash: printf "e[1;34m[Suite]e[00mn"
Is there an easy way to output color text to the terminal in the nimble file?
I tried using standard terminal codes but that didn't work.
I then found and used the Terminal module. That works in a nim file, see the

Is it possible to pass 3 or more parameters to a pragma or block type macro?
For example, say I want to pass an int and string to a pragma macro. The

Thank you for the responses and code, I'm learning a lot about the macro
system. Nice idea to use a pragma.
Testing the macro I was getting the compiler error:

I used treeRepr in the macro to debug the problem. It turned out I was putti
Using include is an interesting idea, it adds another dimension to consider.
Including allows you to group all module tests together which I want, however
it requires you run in the main module. I want to run in an external module to
more closely match how a user would use the code.
I didn't an
I'm testing my module's procedures in an external test module. This works great

Thank you very much.
