Authors/Port authors:

Agena is an easy-to-learn procedural programming language suited for everyday usage. It has been implemented as an interpreter and can be used in scientific, educational, linguistic, and many other applications. Its syntax looks like very simplified Algol 68 with elements taken from Lua and SQL.

This software is distributed as compressed package. You have to download and manually install it; if prerequisites are required, you will have to manually install them too.

Manual installation

Available both as 7 ZIP and WarpIN package:

  • download the 7 ZIP package to temporary directory and unpack it to destination folder;
  • the WarpIN package is self-installing.

See below for download link(s).

You can install the prerequisites with rpm running the following string in a command line:

yum install libc libcx libgcc1 libssp libstdc++6 libstdc++ libsupc++6 libsupc++ libgcc-fwd readline ncurses

Following ones are the download links for manual installation:

Agena v. 3.14.0 (23/4/2024, Alexander Walz) Readme/What's new
3.14.0 Scottsboro, April 23, 2024 - The assignment feature in `if` and `while` clauses has been extended: You can now use the percentage sign as a placeholder for the variable name in the actual condition, for example: > i := 0.1; > while logn := ln(i), % < -0.9 do > print(i, logn); > i +:= 0.1 > od; 0.1 -2.302585092994 0.2 -1.6094379124341 0.3 -1.2039728043259 0.4 -0.91629073187416 When using the `percentage notation` with `while` loops, the variable name is always reassigned when control flow is returning to the start of the `while` loop, before checking whether to execute the loop body once again. This is contrary to the existing logic where the assignment is done only once, so the following will loop forever since `logn` is not updated in the loop body: > i := 0.1; > while logn := ln(i), logn < -0.9 do > print(i, logn); > i +:= 0.1 > od; The percentage sign cannot be used in the body or succeeding statements as it usually represents the modulus operator. - This release has been named after the city of Scottsboro, Jackson County, Alabama. It has been Valgrind-checked on x86 and AMD64 Linux to ensure there are no internal errors or memory leaks.
Agena v. 3.11.5 (24/3/2024, Alexander Walz) Readme/What's new
3.11.5 Converse, March 24, 2024 Tuned, extended and fixed calculus functions that compute integrals: - `calc.intdei` and `calc.intdeo` now remember the last epsilon setting given by the user and run 40 % faster with succeeding calls done with the same epsilon value. This also benefits the wrapper function `calc.integ` (see below). - `calc.gauleg`, `calc.intde`, calc.intdei`, `calc.intdeo` and `calc.intcc` now accept multivariate functions. See the Primer and Reference on how to pass the second, third, etc. arguments in the respective calls. With univariate functions, as before, you do not have to change the code. - `calc.integ` has been rewritten to support multivariate functions. Optional epsilon, omega and sample values must now be given as explicit options, so you may have to adapt your code. Example: > calc.integ(<< x, a -> x + a >>, 1, 2, 0, eps=hEps, omega=1, samples=100): 1.5 2.999999997239e-015 - If the third argument to `calc.intdeo` was zero, the interpreter could crash on some platforms. This has been fixed. - If the number of sample points is zero, `calc.gauleg` now automatically sets it to 20 points internally. This prevents segmentation faults on some platforms and also false results of exactly zero. - If you pass zero as an epsilon value to `calc.intde`, calc.intdei`, `calc.intdeo` and `calc.intcc`, then it is automatically reset to the default setting 1e-15 to avert any infinite loops. - This release has been Valgrind-checked on x86 and AMD64 Linux to ensure there are no internal errors or memory leaks.
