Simple question :
I am using cmder and i would like to be able to define ~(or ~USERID) as my %USERPROFILE% environment variables. I edited %CMDERROOT%\config\aliases to add this line : ~=%USERPROFILE% it does work for ls command but not for cd for instance.
Is there a better way to have this unix-like user profile aliases ?
For those who would like an answer to that question, it have been addressed in the following github issue :
https://github.com/cmderdev/cmder/issues/41
Not a direct answer, but a decent work-around was mentioned in the discussion on that page:
clink, the vendor package that would handle this has a similar issue report marked as "wontfix" So, here's the workaround
I'm using an AutoHotKey script for that:
#IfWinActive ahk_class VirtualConsoleClass
::~::D:/nicolas
#IfWinActive
It replaces automatically ~ with D:/nicolas in ConEmu console (and only ConEmu console)
I have not tried it in a script executed from the command line, but it works from the command line directly, as nicolas suggests.
I don´t remember where I got it but add these lines to your profile:
function cuserprofile { Set-Location ~ }
Set-Alias ~ cuserprofile -Option AllScope
you just hit ~ (enter) and you'll send to your home directory.
PS. I'm using PowerShell in cmder, regards.

I have the following code that should open the Recode.xlsx inside the subf folder but doesn't
write_xlsx(mtcars, "subf/Recode.xlsx")
shell("subf/Recode.xlsx", wait=FALSE)
The following code works, so if anyone has an idea on why it doesn't work it would help me
write_xlsx(mtcars, "Recode.xlsx")
shell("Recode.xlsx", wait=FALSE)
Here’s what the documentation of the shell function says (emphasis mine):
shell is a more user-friendly wrapper for system. To make use of Windows file associations, use shell.exec.
And here is another bit of relevant information from the shell.exec documentation:
To be interpreted as relative, the path also needs to use backslashes as separators (at least in Windows 10).
So the following is the correct usage:
shell.exec("subf\\Recode.xlsx")
I created a alias to the directory data,
now I want to be able to access subdirectories for a script in the same manner as a normal directory, for example data/sub1.
The alias on its own works in the terminal but I can't access the path it stands for ( /User/usr/Folder/Subfolder/data ) in the command line arguments of the script.
python skript.py -input data/path/ -output data/path.
I tried $data, {data} and different quotation marks around the path but wasn't able to access it.
I saw that at some similar questions link -ln was suggested but it sounds like this is similar to an environment variable, the later didn't work for me reliably therefor I haven't tried the link yet.
Any suggestions, again I would prefer the alias but I'm open for anything else.
Kind regards
Right now I'm trying to create wallet for TON.
I downloaded and built Fift interpreter an was trying to create new wallet with: ./crypto/fift new-walelt.fif
[ 1][t 0][1559491459.312618017][fift-main.cpp:147] Error interpreting standard preamble file `Fift.fif`: cannot locate file `Fift.fif`
Check that correct include path is set by -I or by FIFTPATH environment variable, or disable standard preamble by -n.
Although my path variable is set. Could anyone please help me with this?
First, locate {{lite-client-source-direcotry}}/crypto/fift
This is not the build directory, that's the directory where are the source files (lite-client that you downloaded). So verify you have that it contains Fift.fif file.
If you installed it in the user working directory, it should be:
~/lite-client/crypto/fift/
Now, you should either set FIFTPATH variable to point to this directory or run fift with -I option:
export FIFTPATH=~/lite-client/crypto/fift/
./crypto/fift new-walelt.fif
Or
./crypto/fift -I~/lite-client/crypto/fift/ new-walelt.fif
Have you tried ./crypto/fift -I<source-directory>/crypto/fift new-wallet.fif instead of setting environment variable? Are Fift.fif and Asm.fif library files inside FIFTPATH?
Make sure you have followed all the instruction written here:
https://test.ton.org/HOWTO.txt
It should work if you do all the above instruction correctly. If not, it might be a bug. Remember that TON is in a very early beta strage. You can submit the issue here:
https://github.com/copperbits/TON/issues
You also can use this:
cd ~/liteclient-build
crypto/fift -I/root/lite-client/crypto/fift/lib -s /root/lite-client/crypto/smartcont/new-wallet.fif -1 wallet_name
Try this (worked for me)
export FIFTPATH=~/lite-client/crypto/fift/lib
./crypto/fift new-wallet.fif
I want to run simple go code directly from terminal/command line. For example:
go run "
package main
func main() {
println("hello")
}
"
hello
However golang allows code execution only from file. So maybe there are some ways how to emulate it? Like this:
go run file.go < echo "...."
But there should be no files after actions above.
In command-line, only a project like go-repl would compile/run a multi-line go source code without leaving any .go file behind.
An alternative: gore:
$ gore
Enter one or more lines and hit ctrl-D
func test() string {return "hello"}
println(test())
^D
---------------------------------
hello
(Other repl-like solution are listed in "Does Go provide REPL?")
Or you would need to develop a go wrapper which would internally create a source code and go run it, before deleting it.
Ubuntu has a gorun tool which works well for small scripts. It compiles scripts on the fly, caching the binaries in /tmp.
https://wiki.ubuntu.com/gorun
Although it's intended for scripting and not as a REPL, you could use it in various ways.
Although gorun has come from the Ubuntu community, it should work on any Linux distro because it uses vanilla Go source code via
$ go get launchpad.net/gorun
Currently an example line of my terminal will start with -> ~ git:(master)
But I'd like to update it to use the current user too: -> [tom] ~ git:(master)
Right now I'm using oh-my-zsh and I thought to override it, I'd add something to my .zshrc file, but I can't seem to find out where/what to add
You can use a zsh prompt expansion sequence, found in the manual page for zshmisc.
If you're using oh-my-zsh it's a bit tricky: you need to figure out what theme you're using, then modify it to include the right prompt sequence. The themes are kept in $HOME/.oh-my-zsh/themes. If you're really stuck, you could include the theme you're using in your question :)
The prompt expansion you're probably looking for is %n, which expands to $USERNAME.
