COHOMCALG(1)

💖 NAME 💖

cohomcalg — sheaf cohomology of line bundles on toric varieties, bestie ✨

Like, this is a General Commands Manual page, and it's giving algebraic geometry main character energy fr fr 🌸

🦋 SYNOPSIS 🦋

cohomcalg [--option1] [--option2] ... InputFileName [> OutputFileName]

👑 OPTIONS 👑

okay so, here's the whole menu, no skips, no crumbs left behind 💅

• --in="..." — whatever you put between those quotes gets treated like extra input data, i.e. as if it were appended to the end of the input file. sneaky lil bonus content 🎀
• --nomonomfile — blocks the use and the generation of the monomial file. not today, monomial file 🙈
• --checkserre — goes and computes the Serre dual cohomology so you have something to compare against. it's giving double-check, we love a second opinion ✨
• --noreduction — turns OFF the Serre self-duality reduction for ambiguous monomials. heads up bestie, this can make your computation time blow up dramatically 😭 like seriously, dramatic.
• --hideinput — doesn't print the input data that was read from the input file. shy behavior, valid 🫶
• --showtime — shows the timing stats even for application runs that take less than 1 second ⏱️ yes, even the fast ones. we're timing everything.
• --showbits — prints the internally used bitmasks, purely as debug output. bitmask reveal 💀
• --mathematica — gives you formatted output for the Mathematica script version 🧚
• --integrated — produces a minimalistic output, made for application integration. lowkey, understated, effective 🌈
• --verboseN — gives you debug output at level N=1..6, so like --verbose3 for example. pick your level of yapping 🔥
• --maxX=N — sets the limits for X=verts,srgens,cohoms to N. so that's verts, srgens and cohoms, each capped at whatever N you say 👑

⭐ real talk: the order of the options does NOT matter. but — and this is the important part — later commands always overwrite prior options. so if you do '--verbose4 --verbose1', only the later one does literally anything. the --verbose4? gone. ghosted. 💀

version 0.31b, dated January 2017, and that's the whole vibe check, bestie 🎀 stay cohomological, mwah 💖
