I'm trying to setup a new project in F#.
I'm using FsLexYacc as a tool, and last time i used it was when the Fsharp powerpack was 'in'. The documentation on the site are not that good. It also seems to me that there is a bug with the generic type annotation 'end since it is a keyword..
but I'm in first place just copy pasting the dummi files from the page to make sure the makefile are up and running. (lexer, parser, and program)
page:
https://fsprojects.github.io/FsLexYacc/index.html
I then get the
../../FSharp/Project/src/Lexer.fsl(21,81): error FS0001: The type 'char' does not match the type 'byte'
Have tried to enforce the type by changing _ to byte that didn't help at all
Makefile:

I tried this, but I was not able to reproduce your error. Here is what I'm doing. Is there something I'm doing differently than you?
I copied the Lexer.fsl file from the repository:
{
// Opens methods related to fslex.exe
open FSharp.Text.Lexing
let newline (lexbuf: LexBuffer<_>) =
lexbuf.StartPos <- lexbuf.StartPos.NextLine
}
// Regular expressions
let whitespace = [' ' '\t' ]
let newline = ('\n' | '\r' '\n')
rule tokenstream = parse
// --------------------------
| "hello" { Parser.HELLO }
// --------------------------
| whitespace { tokenstream lexbuf }
| newline { newline lexbuf; tokenstream lexbuf }
// --------------------------
| _ { failwith ("ParseError" + LexBuffer<_>.LexemeString lexbuf) }
| eof { Parser.EOF }
And the Parser.fsy file:
%{
%}
// The start token becomes a parser function in the compiled code:
%start start
// Regular tokens
%token HELLO
// Misc tokens
%token EOF
// This is the type of the data produced by a successful reduction of the 'start'
// symbol:
%type < int > start
%%
// These are the rules of the grammar along with the F# code of the
// actions executed as rules are reduced.
start: File end { $1 }
| end { $1 }
File:
| HELLO { 1 }
| HELLO HELLO { 2 }
// Using F# keywords for nonterminal names is okay.
end: EOF { 3 }
And run the following command to compile the two:
fsc Parser.fs Lexer.fs -r C:\[my work folder]\FsLexYacc\src\FsLexYacc.Runtime\bin\Debug\netstandard2.0\FsLexYacc.Runtime.dll
The source code in the generated Lexer.fs looks something like this:
module Lexer
# 1 "Lexer.fsl"
// Opens methods related to fslex.exe
open FSharp.Text.Lexing
let newline (lexbuf: LexBuffer<_>) =
lexbuf.StartPos <- lexbuf.StartPos.NextLine
# 12 "Lexer.fs"
let trans : uint16[] array =
[|
(* State 0 *)
[| 5us;5us;5us;5us; (* lots more here... *)|];
(* lots more states here... *)
(* State 11 *)
[| 65535us;65535us;65535us; (* lots more here... *)|];
|]
let actions : uint16[] = [|65535us;3us;1us;2us;3us;3us;4us;2us;65535us;65535us;65535us;0us;|]
let _fslex_tables = FSharp.Text.Lexing.UnicodeTables.Create(trans,actions)
let rec _fslex_dummy () = _fslex_dummy()
// Rule tokenstream
and tokenstream lexbuf =
match _fslex_tables.Interpret(0,lexbuf) with

I want to disable the user password when a VM is creating using this command:
sudo sed -i -E '/^username/s/^([^:]*):([^:]*):([^:]*):([^:]*):([^:]*)(:.*)$/\1:!!:'$(($(date +%s)/86400))':\4:99998\6/' /etc/shadow
in Terraform virtual_machine_extension. I´ve tested the command on a freshly created VM and it works, but when using it with Terraform I get this Error:
Error: Code="VMExtensionProvisioningError" Message="VM has reported a failure when processing extension 'vm-02'. Error message: \"Command returned an error.\n---stdout---\n\n---errout---\nsed: -e expression #1, char 71: unterminated `s' command\n\n\"."
on ../modules/vm.tf line 100, in resource "azurerm_virtual_machine_extension" "disable_pw":
100: resource "azurerm_virtual_machine_extension" "disable_pw" {
I already tried to escape \ with \\. Running this exact vm_extension with other bash commands works fine.
Did someone has experience in it?
resource "azurerm_virtual_machine_extension" "disable_pw" {
name = "${var.vm_hostname}
location = "${module.global_variables.location}"
resource_group_name = "${module.global_variables.resource_group_name}"
virtual_machine_name = "${azurerm_virtual_machine.vm-linux.name}"
publisher = "Microsoft.OSTCExtensions"
type = "CustomScriptForLinux"
type_handler_version = "1.5"
auto_upgrade_minor_version = false
protected_settings = <<SETTINGS
{
"commandToExecute": "sudo sed -i -E '/^username/s/^([^:]*):([^:]*):([^:]*):([^:]*):([^:]*)(:.*)$/\1:!!:'$(($(date +%s)/86400))':\4:99998\6/' /etc/shadow"
}
SETTINGS
settings = <<SETTINGS
{
}
SETTINGS
}
This will work
sed -E '/^username/s/^([^:]*):([^:]*):([^:]*):([^:]*):([^:]*)(:.*)$/1:!!:'$(($(date +%s)/86400))':4:999986/g' /etc/shadow
Explanation:
s/ is used after checking the required username.
use '\' escaping only for special characters like regex.
i have command that outputs a collection strings that look like this:
json.formats[0]].url = "https://example.com/ar.html"
json.formats[1].url = "https://example.com/es.html"
json.formats[2s].url = "https://example.com/ru.html"
json.formats[3].url = "https://example.com/pt.html"
json.formats[73].url = "https://example.com/ko.html"
json.formats[1502].url = "https://example.com/pl.html"
(there are many more instances, however for simpilcity's sake theyve been removed)
i can use the command below
myCmd | grep -e 'json\.formats\[.*\]\.url\ \=\ '
however i only want the wildcard to match integers, and to throw out non-integer matches. it gives me the following:
json.formats[0]].url = "https://example.com/ar.html"
json.formats[1].url = "https://example.com/es.html"
json.formats[2s].url = "https://example.com/ru.html"
json.formats[3].url = "https://example.com/pt.html"
json.formats[73].url = "https://example.com/ko.html"
json.formats[1502].url = "https://example.com/pl.html"
what i really want is this:
json.formats[1].url = "https://example.com/es.html"
json.formats[3].url = "https://example.com/pt.html"
json.formats[73].url = "https://example.com/ko.html"
json.formats[1502].url = "https://example.com/pl.html"
Thanks :-)
You may use:
myCmd | grep -E 'json\.formats\[[[:digit:]]+\]\.url = '
or:
myCmd | grep -E 'json\.formats\[[0-9]+\]\.url = '
[[:digit:]] is equivalent of [0-9] for most of the locales.
Below is my script that acquire the MAC of the machine and store within a config file.
My problem is that within each line have the character " " and it dont print it inside the file, how can I write the file using " "
MAC=$(ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}')
echo "
view.sslVerificationMode = *3*
view.autoConnectDesktop = *TRUE*
view.autoConnectBroker = *TRUE*
view.kioskLogin = *TRUE*
view.nonInteractive = *TRUE*
view.fullScreen = *TRUE*
view.nomenubar = *TRUE*
view.defaultBroker = *viewcs*
view.defaultUser = *CM-${MAC//:/_}*
" > /etc/vmware/view-mandatory-config;
sed -i 's/*/"/g' /etc/vmware/view-mandatory-config
with cat and a here-doc you can use multi-line input without escaping charaters
MAC=$(ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}')
cat << EOT > /etc/vmware/view-mandatory-config
view.sslVerificationMode = "3"
view.autoConnectDesktop = "TRUE"
view.autoConnectBroker = "TRUE"
view.kioskLogin = "TRUE"
view.nonInteractive = "TRUE"
view.fullScreen = "TRUE"
view.nomenubar = "TRUE"
view.defaultBroker = "viewcs"
view.defaultUser = "CM-${MAC//:/_}"
EOT
cat will relay the stdin input generated by the here document to stdout, thus enabling redirection to a file
Simply escape double-quotes within the outer double-quotes by putting a backslash in front of them:
MAC=$(ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}')
echo "
view.sslVerificationMode = \"3\"
view.autoConnectDesktop = \"TRUE\"
view.autoConnectBroker = \"TRUE\"
view.kioskLogin = \"TRUE\"
view.nonInteractive = \"TRUE\"
view.fullScreen = \"TRUE\"
view.nomenubar = \"TRUE\"
view.defaultBroker = \"viewcs\"
view.defaultUser = \"CM-${MAC//:/_}\"

Xcode allows you to create automated scripts for performing repetitive tasks. What scripts have you written to speed up development?
I've created three for my JSON.Framework for Cocoa and the iPhone. These take care of the following:
Creates a release Disk Image with dynamic embedded Framework, custom iPhone SDK, API documentation and some documentation files in.
Run Doxygen over the source to create an Xcode-compatible documentation set and install this. This means when you search for things in Xcode's documentation search your documentation can be found too.
Run Doxygen over the source to update a checked-in version of the API documentation in the source tree itself. This is pretty neat if you use Subversion (which it assumes) as the documentation is always up-to-date for the branch you're in. Great if you're hosting on Google Code, for example.
Beware some hard-coded project-specific values in the below. I didn't want to potentially break the scripts by editing those out. These are launched from a Custom Script Phase in Xcode. You can see how they're integrated in the Xcode project for the project linked above.

This is an improvement of the "Create Property and Synths for instance variables" script that Lawrence Johnston posted above.
Settings:
Input: Entire Document
Directory: Home Directory
Output: Discard Output
Errors: Ignore Errors (or Alert if you want to see them)
Select any number of variables and it'll create properties and syns for all of them. It'll even create/edit your dalloc method as necessary.
Edit up the results if they are not exactly right (copy vs. retain, etc.)
Handles more things like underbar storage name, behavior, dealloc,…

Here's one to log a method and its arguments any time it's executed (Select the method definition up through the lie with the opening brace and execute the script). If FIXME shows up in the output it means it's an unrecognized type. You can either add it to the script or choose the proper format specifier manually.

Here's one to create a -description method for a class. Highlight the instance variables declaration section (#interface ... { ... }) and execute the script. Then paste the result into your implementation. I use this one along with po objectName in GDB. If FIXME shows up in the output it means it's an unrecognized type. You can either add it to the script or choose the proper format specifier manually.

Here's one that I found somewhere else that creates #property (copy) and #synthesize property directives for an instance variable. It could use a bit of improvement (say, to let you synthesize multiple variables at once), but it's better than creating them by hand.
Select the instance variable you want to create a property for and activate the script.
If I want a (retain) instead of (copy) I just activate the script and change it to retain manually (it's smart enough to not include the (copy) on primitive types such as int to begin with).
