Ideally, I would like to have dartfmt to format my code on every commit, and I think that git hooks are ideal for this. So far, I've tried the code found in this link, but with no success, despite it appearing on multiple other websites — maybe it's outdated.
In the end, I think nothing much more complicated than this should work in most cases (inside the .git/hooks/pre-commit file):
#!/bin/bash
dartfmt -w . # or maybe `flutter format .` for Flutter
The errors I get are:
For dartfmt -w .: dartfmt: command not found
For flutter format .: find: ‘> bin [’: No such file or directory
Both of those commands do work if placed directly in the terminal.
to make dartfmt work, try running which dartfmt manually to get the path to the executable, and then use the absolute path when calling it in the script.
If which isn't able to find it, and assuming you know the complete path to the directory where dartfmt is located, try adding that directory to PATH in the script:
#!/bin/bash
PATH="/path/to/dart-sdk/bin:$PATH"
export PATH
Also, I'd suggest taking a moment double check what git will use for the working directory when it calls those hook scripts. There might be some undesired behavior by using . if the CWD isn't what is expected. See this post.
To format your dart code regularly, you can follow one of the two ways mentioned below:
Preferred way:
In IntelliJ Idea go to Settings -> Language & Frameworks -> Flutter -> Select Format Code on save option.
This will format your code every few seconds. This is preferred because you can customize your personal formatting settings such as max words in a line etc.
Alternatively
From Official website run dartfmt -w bin lib to format your code from the command line.
Add dartfmt reference in PATH, like this:
export PATH="/xxx/flutter/bin/cache/dart-sdk/bin:$PATH"

If I try to run virtualenv, I get this message:
$ virtualenv
-bash: /Users/me/Library/Python/3.6/bin/virtualenv: No such file or directory
It's not surprising that this happens, because I've removed this directories at an earlier point when trying to clean up my computer from different Python versions. However, how does my system know to look in that directory for virtualenv? I've looked in my bash profile, and there is no mention of virtualenv there.
When you type something your command interpreter has to search the command. Of course it cannot try every possible directory on your system. Then it provides to the user a way to control that process. This is the purpose of the PATH environment variable :
$ echo $PATH
will show you the actual value which looks like dir1:dir2:...:dirn, meaning that commands where searched for in dir1, then dir2, etc. You have to remove the value /Users/me/Library/Python/3.6/bin/ from it. The best way is to edit the .bashrc or .bash_profile file to remove the permanent setting of this variable. Then reconnect.
I would like to see what mistakes I made in my golang files. In order to figure it out, I issue a command like this:
gofmt -d myfile.go
According to the gofmt --help manual, it is supposed to list the diff of the current and the desired versions of the file. Instead of this, it produces this error message:
computing diff: exec: "diff": executable file not found in %PATH%
How could this be fixed?
The gofmt tool assumes the system has an installed and available diff. Unfortunately, this tool is not part of a standard Windows installation so you need to add it manually.
For most of us, the easiest way to add the path of the diff tool we already have on our computer. This is the one that has been installed as part of git. (If git hasn't been installed yet then do it at first.)
In order to solve this, you should issue a command from the DOS prompt in which you want to execute gofmt:
set PATH=%PATH%;c:\Program Files\Git\usr\bin
(Maybe you need to change the path according to your git installation.)
For a more permanent solution, you should add the path of diff.exe to the PATH environment variable via the Control Panel.
I'm using #angular/compiler-cli to build my ng2 app in aot mode. When I input 'ngc -p tsconfig-aot.json' in my bash window, I get 'bash: ngc: command not found'. However, when I use 'node_modules/.bin/ngc -p tsconfig-aot.json' instead, it works. I googled for serval times but didn't get any usfull information. Can any give me a hand? Thx!
Seems like you need to put ngc in your path:
echo $PATH
Do you see ngc in binary in your path?
If not:
PATH=$PATH:/path/to/ngc
To make it permanent add to .bash_profile
export PATH=$PATH:/path/to/ngc
I've tried to change the slash to 'backslash' on windows and it worked for me:
node_modules\\.bin\ngc
If you don't want to set it globally, you can specify an absolut path in your angular-project, just make sure that you delete this part of the path when you don't use it anymore.
ngc is in node_modules/.bin, so depending on where you want to use ngc you can export the path like this:
PATH=$PATH:../../../node_modules/.bin
To run commands located into the node_modules folder of your project, without installing them globally (operation that will make the ngc command work in any system folder), you can use this command:
ngx ncc <options>
Basically ngx is a shortcut that executes any command located in node_modules bin folder.
I am attempting to write a build script to be used with Facebook watchman and my ember-cli application.
My build script is:
#!/bin/sh
cd ..
ember build
cd ..
cp ./ember-app/dist/index.html ./slim-app/app/templates/app.php
cp -r ./ember-app/dist/assets/ ./slim-app/public/assets/
And my watchman command is:
watchman -- trigger $PWD/ember-app/app 'ember-build' '**' -- sh $PWD/build.sh
Watchman triggers and finds my script fine but when I look at the log I get an error saying ember cannot be found. I'm not really sure why because when i run sh build.sh everything works fine.
Is there any way I could do something like which ember to determine the path to ember and use it directly? I know I can just do which ember and copy and paste that path into the script but I really don't want to do that because I want the build script to work no matter which version of node/nvm I am using.
I'm also open to suggestions to a better way of doing this.
Sounds like a PATH problem. When watchman is first started it captures your PATH environment variable, except on OS X at the moment, due to a bug in our launchd integration.
https://github.com/facebook/watchman/issues/68 has some suggestions for an awkward workaround.
Another possibility is to simply put a line in your build script to set the PATH:
# Add the path to ember in here somewhere
PATH=/usr/local/bin:$PATH
Looking for a solution to quickly navigate to long paths in a shell (particularly Max OS X Terminal.app).
Say my path is ~/This/Is/A/Really/Long/Path/That/I/Would/Rather/Not/Type/Frequently
Instead of cd ~/This/Is/A/....
I would like to be able to store favorites/bookmark directories so I could do "cd myPath"
Are there any binaries or tools available to do something like this?
I've found the packages 'Apparix' and 'Goto' which together make the stuff dreams are made of for us terminal junkies.
Naturally, I had trouble installing Apparix, but I figured it out in the end.
How To Install Apparix on Mac OS X:
Download the tarball from Apparix's homepage.
Unpack the tarball, cd to the unpacked folder.
Run this command ./configure --prefix=$HOME/local && make && make install.
Run man apparix, scroll down to the heading BASH-style functions, copy everything within that section (delimited with ---) and paste it into ~/.bash_profile.
That's it. You should now have Apparix up and running on OS X (further install info and usage is on Apparix's homepage).
Another solution is to use Bashmarks, which allows you to this
$ cd ~/This/Is/A/Really/Long/Path/That/I/Would/Rather/Not/Type/Frequently
$ s shortname # save current path as `shortname`
$ cd /
$ g shortname # cd to ~/This/Is/A/Really/Long/Path/That/I/Would/Rather/Not/Type/Frequently
You can use aliases (stick them in your ~/.bash_profile if you want them to always load)
alias cd_bmark1='cd ~/This/Is/A/Really/Long/Path/That/I/Would/Rather/Not/Type/Frequently'
Then use by just typing
cd_bmark1
into the console
I know you already found an answer that worked for you, but a couple of more lightweight suggestions that might help others looking for similar things
If your directories are relatively fixed, just long and far away from each other, you can use the CDPATH environment variable to add directories to the search path when typing the "cd" command. If the directory name you try to cd to isn't in the current directory, the other entries in your CD path will also be looked at (and it's also tab complete aware, at least in bash and zsh).
Switching to zsh rather than bash and using the excellent directory stacks abilities. With it, you can maintain a history of directories that you've visited, view the history with the "dh" alias, and easily switch to a directory by using quick shortcuts (ex: cd -3 to switch to the 3rd directory in your history stack).
Why not having a symlink ?
ln -s ~/This/Is/A/Really/Long/Path/That/I/Would/Rather/Not/Type/Frequently bmark
cd bmark
I use to.sh daily to create and navigate bookmarked paths in bash. It supports tag autocompletion and the ability to easily add/remove bookmarks.
