reStructuredText – document title and subtitle
Posted by jpluimers on 2020/04/21
Always watch how you format your reStructuredText sections: [WayBack] Docutils FAQ: 2.6 How can I indicate the document title? Subtitle?
That is why I have these comments at the top of most of my documents:
.. $ %
.. # * = + ^ ~ - : . _ ` ' "
The first two are the document title and subtitle marks, the others the level 1 through 13.

Is there no shortcut in the IDE for Quick Edit?
Posted by jpluimers on 2020/04/21
I hope this feature gets added: [WayBack] Is there no shortcut in the IDE for Quick Edit? – Reinier Sterkenburg – Google+.
The thread evolved into a few posts about failing keyboard handling (including Shift-F10) which has been failing for a long time and known to the development team for almost that time.
Hopefully things like that get fixed one day as well.

Passing parameters to a Bash function – Stack Overflow
Posted by jpluimers on 2020/04/20
Since I tend to forget this:
- you can declare bash functions with parenthesis
- you pass parameters to functions space delimited (often people quote each parameter)
- within functions you can refer to parameters by number just like the parameters passed to a shell script
More info at:
- [WayBack] Passing parameters to a Bash function – Stack Overflow
- [WayBack] Complex Functions and Function Complexities
I think for functions, you can apply what is linked from Some useful links on bash parameters: $1, $*, $@, quotes, etc., so a loop over all parameters in a function is the same as in a script, see [WayBack] shell – how to loop through arguments in a bash script – Unix & Linux Stack Exchange from Gilles:
There’s a special syntax for this:
for i do echo "$i" doneMore generally, the list of parameters of the current script or function is available through the special variable
$@.for i in "$@"; do echo "$i" doneNote that you need the double quotes around
$@, otherwise the parameters undergo wildcard expansion and field splitting."$@"is magic: despite the double quotes, it expands into as many fields as there are parameters.print_arguments () { for i in "$@"; do echo "$i"; done } print_arguments 'hello world' '*' 'special !\characters' # prints 3 lines print_arguments '' # prints one empty line print_arguments # prints nothing

sed double expression: match, replace in one line, overwrite file
Posted by jpluimers on 2020/04/15
A while ago, I needed to conditionally replace in files, so I used sed and a regular expression, though usually I dislike those.
However, since the system had a very basic install, there was not much choice.
Luckily back then, my Google foo returned these:
- [WayBack] sed 102: Replace In-Place Replace files in-place with sed’s
-iflag. - [WayBack] Unix Sed Tutorial: Find and Replace Text Inside a File Using RegEx
This allowed me to do a double expression (the first matches a pattern, the second performs the actual replacement within the matching lines).
In case my Google foo in the future fails:
## https://robots.thoughtbot.com/sed-102-replace-in-place
## -i causes no backup to be saved, but does in-place replacement
## since we run under git, we can always restore
## combined with a double expression (the first matches, the second executes) this is very powerful

Binary search for finding problematic versions: install a specific version in homebrew and git bisect
Posted by jpluimers on 2020/04/14
I’ve used these excellent posts to find out which youtube-dl version started to exhibit troublesome NPO downloads, then later find the actual failing commit:
- [WayBack] Install a specific version of a formula with homebrew – Zoltan Altfatter – Software Engineer
- [WayBack] How to use git bisect? – Stack Overflow
Why the effort? I needed an as recent as possible youtube-dl working on as many sites as possible because of some work preparation.
The first link is very important because brew versions and alternatives have stopped working some 6 years ago, even though they turn up high on Google searches for brew install specific version. Hence the quote from the first link:
Installing software packages on Mac is very easy with homebrew. You typically get the latest version, however often in production you do not have the latest version of a software package. Another use case is when you upgrade to the latest and you find out there is bug which blocks you doing something. In this case you would like to downgrade to the previous version until the bug is fixed.In both cases you need to install a specific version of a software package with homebrew on your Mac, which tends to be not that trivial. There is a lot of discussion about this on stackoverflow but some of them are outdated based on brew versions which is not available anymore.

Bug Finder, A Real Win32 Extensible Passive Debugger – CodeProject
Posted by jpluimers on 2020/04/09
On my research list is [WayBack] GitHub – DareDevil73/bug-finder: Windows passive debugger. with an article at [WayBack] Bug Finder, A Real Win32 Extensible Passive Debugger – CodeProject:
The Bug Finder is a real Win32 debugger, entirely written in Borland Delphi, which analyzes your application execution flow, so you can:
- Catch exceptions on the main executable, external DLLs, primary and working threads.
- Produce a detailed stack trace about each exception.
- Place a symbolic breakpoint to get, in place of a program debug break, a full stack trace log message (dynamic tracing).
- Produce detailed and rotative log files for a batch application behaviour inspection.
- Capture output of
OutputDebugStringAPI to log file (to provide extra debugging information by yourself directly into your code).- Trace Process, Threads and DLLs activities.
I found documentation at [WayBack] DareDevil73 … docs, but the binary dependencies and installer are on SourceForge (where the project was originally located) and CodeProject which cannot be archived so I will look into that when it pops to the top of my research list.

Hashes and their uses – The Isoblog.
Posted by jpluimers on 2020/04/09
A nice introduction to [WayBack] Hashes and their uses – The Isoblog covering:
- Checksums
- Digit sums as simple, weak checmsums
- Better checksums: ISBN-10 as an example
- Proper CRC checksums
- Hashes for storage
- Building dictionaries
- Breaking dictionaries
- Handling collisions
- Cryptographic hashes
