formulae | Parsing and calculating formulae

I am trying to install the hdf5 library from Homebrew. Running brew install hdf5 in the terminal returns the following error message:

==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "hdf5".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

I am running this on a mac with Mojave version 10.14.6. What next steps should I try to download the hdf5 library?

I am trying to generate and draw a sin waves. I am using this formulae that I found online y = Amp * sin(2 * PI * frequency * time + shift)

I'm trying to install an older version of CMake to compile a software that requires it (https://github.com/horosproject/horos)

If you use brew install cmake it will install 3.20 versions, but I need to install 3.19.2 to get the compilation to work.

You would think this would be easy but I have been struggling. Here are some things I have tried:

...

Simply put: I want to list the last N packages I've installed with Homebrew.

What is the best (and possibly fastest) way to accomplish this?

Note that I'm not fluent in Ruby, so any suggestions to 'hack the Homebrew code to do what you want' would get me nervous...

What I tried so far

1. Read man pages, documentation, the Homebrew website, StackOverflow, googled with all sorts of variant questions, etc. No luck so far.
2. brew info [formula|cask] will actually tell the date when a formula/cask has been poured (which I assume means 'installed' outside the Homebrewosphere). So that value must be written somewhere — a database? a log?
3. Maybe there is an option to extract the poured date information via the JSON API? But the truth is that with Homebrew 3.1.9-121-g654c78c, I couldn't get any poured-date or similar element on the JSON output... the only dates that I get are related to git (presumably because they're more useful for Homebrew's internal workings). This would, in theory, be able to tell me what are the 'newest' versions of the formulae I have installed, but not the order I have installed them — in other words, I could have installed a year-old version yesterday, and I don't need to know that it's one year old, I only want to know I've installed it yesterday!

What I learned so far

Although I couldn't figure out how to retrieve that information, I'm sure it is there, since brew info ... will give the correct day a particular formula was poured. Thus, one possible solution would be to capture all the information from brew info and then do a grep on it; thus, something like brew info | grep Poured should give me what I want. Needless to say, this takes eternities to run (in fact, I never managed to complete it — I gave up after several minutes).

Of course, I found out that there is a brew info --installed option — but currently, it only works with JSON output. And since JSON output will not tell the poured date, this isn't useful.

A possibility would be to do it in the following way:

• Extract all installed package names with brew info --installed --json=v1 | jq "map(.name)" > inst.json
• Parse the result so that it becomes a single line, e.g. cat inst.json | tr -d '\n\r\[\]\"\,'
• Now run brew info --formula (treat everything as a formula to avoid warnings) with that single line, pipe the result in another file (e.g. all-installed.txt)
• Go through that file, extract the line with the formula name and the date, and format it using something like cat all-installed.txt | sed -E 's/([[:alnum:]]+):? stable.*\n(.*\n){3,7}^ Poured from bottle on (.*)$/\1 -- \3\\n/g' | sort | tail -40 — the idea is to have lines just with the date and the formula name, so that it can get easily sorted [note: I'm aware that the regex shown doesn't work, it was just part of a failed attempt before I gave up this approach]

Messy. It also takes a lot of time to process everything. You can put it all in a single line and avoid the intermediary files, if you're prepared to stare at a blank screen and wait for several minutes.

The quick and dirty approach

I was trying to look for a) installation logs; b) some sort of database where brew would store the information I was trying to extract (and that brew info has access to). Most of the 'logs' I found were actually related to patching individual packages (so that if something goes wrong, you can presumably email the maintainer). However, by sheer chance, I also noticed that every package has an INSTALL_RECEIPT.json inside /usr/local/Cellar/, which seems to have the output of brew info --json=v1 package-name. Whatever the purpose of this file, it has a precious bit of information: it has been created on the date that this package was installed!

That was quite a bit of luck for me, because now I could simply stat this file and get its creation timestamp. Because the formula directories are quite well-formed and easy to parse, I could do something very simple, just using stat and some formatting things which took me an eternity to figure out (mostly because stat under BSD-inspired Unixes has different options than those popular with the SysV-inspired Linux).

For example, to get the last 40 installed formulae:

...

Here is my sample table (for this report I'm using only one table, so there is no table-relationship-links to contend with):

Cost Centre Project Invoice Approver 123 AB Person One 123 AB Person Two 123 ZZ Person One 456 TB Person Three

I have a measure already written Approver = COUNT('Table'[Invoice Approver]). In the sample above, Approver = 4.

I have created a new table showing only those combinations with 1 approver. The table shows 123|ZZ and 456|TB (NOTE: for this table, the approver(s) do not need to be shown, only the unique cost centre/project combinations).

My next step is to have a Card showing the net quantity of the filters: 2. But I need help in writing the DAX measure.

I have tried the following DAX formulae:

Code Result 1InvApp = COUNTROWS(FILTER('Table',[Approver]="1")) "DAX comparison operations do not support comparing values of type Integer with values of type Text." 1InvApp = COUNTROWS(FILTER('Table',[Approver]=1)) Blank (text) 1InvApp = CALCULATE(COUNTROWS('Table'),[Approver]="1") "A function 'CALCULATE' has been used in a True/False expression that is used as a table filter expression." 1InvApp = CALCULATE(COUNTROWS('Table'),[Approver]=1) "A function 'CALCULATE' has been used in a True/False expression that is used as a table filter expression." 1InvApp = COUNTX('Table',[Approver]="1") "DAX comparison operations do not support comparing values of type Integer with values of type Text." 1InvApp = COUNTX('Table',[Approver]=1) "The function COUNTX cannot work with values of type Boolean." 1InvApp = COUNTAX(FILTER('Table',[Approver]=1),'Table'[Approver]) Blank (text) 1InvApp = COUNTAX(FILTER('Table',[Approver]="1"),'Table'[Approver]) "DAX comparison operations do not support comparing values of type Integer with values of type Text." 1InvApp = COUNTROWS(FILTER(ALL('Table'),[Approver]=1)) (as suggested here) Blank (text)

QUESTION: What is the correct DAX syntax to show the desired total result, 2?

Thanks in advance.

I am trying to get the habit to use Dafny as a friendly SAT-QBF solver for some simple formulae, since doing it in, for instance, Z3 is too uncomfortable.

The context for this is that I have implemented Cooper's algorithm for quantifier elimination and, when all the variables are bounded, it can be used as a decision procedure: therefore, I want to know which is the result that I should get before executing it.

However, I encountered a problem in Dafny.

Let us raise, for instance, this formula (written in Dafny):
